--单人花样滑冰的基本技术
之基本滑行动作
双足向前滑行 单足向前滑行 双足向前弧线滑行
单足向前弧线滑行 前交叉步滑行 双足向后滑行
单足向后滑行 双足向后弧线滑行 单足向后弧线滑行
后交叉步滑行 单足半圆弧线滑行 急停动作
单人滑包括男子和女子单人滑两个项目,除个别动作外,男女单人滑基本技术动作和要领是相同的。
单人滑基本技术动作包括基本滑行、基本步法、跳跃、旋转、联合跳跃、联合旋转、接续步和自由滑动作等。
为方便学习,先将常用简化的花样滑冰术语介绍如下:
右 内--右脚冰刀内刃
左 外--左脚冰刀外刃
右前内--右脚前进内刃滑行
左后外--左脚后进外刃滑行
初次上冰不应急于滑行,首先应练习在冰上站稳。其要领是:两脚稍分开与肩周宽,双膝部微屈,两臂向两侧前方伸展(协助掌握平衡),目视正前方,然后再试着走几步,一旦跌倒,要靠自己站起来,以锻炼自己使用冰刀和掌握平衡的能力。下一步便可以开始学习基本滑行技术。
一、单足蹬冰,双足向前滑行 TOP
上体直立姿势,目视正前方,手心向下,两臂向侧前方伸展,双足稍分开,与肩同宽,两只冰刀平行站立。在蹬冰时,首先双膝微屈,然后将重心移至右足,用右足刃前半部份向侧方蹬冰。在完成蹬冰动作后,迅速将蹬冰足收回原位置,将重心放在双足之间,形成双足向前滑行动作,然后再换另一足蹬冰,做同样双足滑行动作。如此反复交替,至比较熟练。
二、单足蹬冰,单足向前滑行 TOP
在比较熟练地掌握了上述动作后,就可以进行单足蹬冰、单足滑行的练习。其准备姿势同前,只是在蹬冰时,身体重心要确实移到滑足上,在蹬冰结束后,要保持重心不变和单足向前滑行姿势,此时蹬冰足应尽快放在滑足足跟后,以保持重心平稳。初练时可以一拍蹬冰一拍滑行,双替进行练习。经过一段练习,重心保持较急后,可以做一拍蹬冰、二拍滑行或三拍滑行。最后可以做一次蹬冰,尽量坚持一次滑行的长度,这样做既可以提高身体保持平衡的能力,也可以练习增加蹬冰力量。
在练习中除应注意内刃侧蹬冰外,还应注意,在做单足滑行时,浮足应跟在滑足足跟后方,共同保持一个重心,两臂要放松,过分紧张不利于保持平衡,滑腿在滑行中应尽量伸直,身体保持直立,不要前倾后仰或左右扭动。一旦失去平衡不必强做挣扎,可顺势倒下,避免外伤,在滑行中还要注意双踝关节保持直立,不能过分向内倒(足外翻姿势是初学者常见的毛病)。踝关节立不直,可能是技术问题,也可能是鞋帮太软或鞋带扎得过松,一旦发现是后者,应立即纠正。
三、单足蹬冰,双足向前弧线滑行 TOP
下面以右足蹬冰,双足向左前弧线滑行为例进行说明。双足呈丁字型站立于冰面上,左足在前,右足在后,双膝微屈,用右足冰刀内刃前部做蹬冰动作,此时身体重心稍向前移至左足外刃一侧,蹬冰后右足尽快回到左足内侧,呈双足滑行姿势,用左前外刃和右前内刃双足向左呈弧线滑行。在滑行中身体重心应稍偏于左足,右足前内刃起支撑协助滑行作用。身体纵轴稍向左倾,两臂自然伸向身体两侧,左臂稍向后,右臂稍向前,这样便于向左呈弧线滑行。
用同样的方法,相反的姿势和动作,做左足蹬冰,双足向前右侧弧线滑行。
在练习以上滑行动作时,要注意身体不能转动过急,身体纵轴倾斜角度不能过大,在练习中要充分体会双足内外刃的用力和重心移动,以便为下一个技术动作打下一个基础。初练时,速度不能过快,伴随着技术的熟练,可以适当加速,加大倾斜角度和弧线的曲度。初学者弧线的曲度能圆的直径为5-7米为宜。
四、单足蹬冰,单足向前弧线滑行 TOP
准备姿势和技术动作与(三)相同,不同之处在于:在蹬冰后应立即将重心移至滑行足,蹬冰足应尽快放在滑足足跟后,足尖向下,呈单足向前弧线滑行姿势。由于是单足滑行,身体重心完全落在滑足冰刀上,身体倾斜要比双足弧线滑行行大一些,两臂应发挥调解平衡的作用,切忌转体过急,造成重心不稳,两侧交替进行练习。
在练习单足弧线滑行时,应在逐步熟练的基础上适当加大单足滑行的时间和距离,为单足半圆滑行打好基础。
此外,单足弧线滑行还有右足蹬冰,左前内刃弧线滑行和左足蹬冰右前内刃弧线滑行和左足蹬冰右前内刃弧线滑行等动作,其技术要领基本相同,只是用刃不同而已,故不一一进行说明。
五、前交叉步滑行 TOP
前交叉步分左前外----右前内交叉步和右前外----左前内交叉步。以前者为例,双足平行站在冰上,首先用右足前内刃蹬冰,在前外刃滑行,身体向左倾斜,左臂在后,右臂伸向前,然后将右足经左

--单人花样滑冰的基本技术
之跳跃动作
华尔兹跳 阿克谢尔跳 沙霍夫跳 路卜跳 点冰路卜跳
菲力浦跳 路兹跳 沃里跳 点冰沃里跳 开腿跳
跳跃动作是花样滑冰中很重要的一个组成部分。跳跃动作的种类很多,一般都以其起跳的用刃、滑行方向、空中转体方式、点冰与否及转体周数等因素来命名和分类。还有的跳跃动作是以世界上第一个完成的人的名字来命名。
跳跃动作之间难度差别较大。不同跳跃难度不同,同一跳跃也因在空中转体周数的不同而不同。周数越多、难度也越高。
任何一种跳跃动作都由准备阶段、起跳、空中动作和落冰动作等四个技术环节所组成。
下面只介绍几种常用的简单跳跃动作:
一、华尔兹跳 TOP
华尔兹跳,也称“3”字跳。它可因跳跃时起跳用刃和落冰是否用同足而有多种跳法。例如“前外—后外不同足华尔兹跳,前外--后内同足华尔兹跳和前内--后外同足华尔兹跳等等,下面以前外—后外不同足华尔兹跳为例进行介绍。
准备动作:右后外刃弧线滑行
起跳用刃:左前外刃
空中转体:180°
落冰用刃:左后外刃
技术要领:右后外刃弧线滑行要平稳,转体180°后,用左前外刃起跳。起跳时,左膝深屈,两臂由后方同时均力向上摆动,带动上体向上,同时滑腿迅速伸直,浮腿也由后方向滑行圆切线方向摆动,在起跳瞬间,滑行刀刃迅速过渡到刀齿,达到制动和起跳的作用。身体在空中应保持直立,两腿分开,转体180°,落冰时,首先用右足刀齿触冰,并迅速过渡到右后外刃滑行,膝部屈曲,起缓冲作用。
以上动作应当迅速进行,各阶段动作要有机协调配合才能使动作连贯优美。两臂动作可以自然伸展,与其它动作配合。在逐步熟练的基础上,可加入舞蹈姿势。
二、阿克谢尔跳(Axel Paulsen) TOP
阿克谢尔跳全称应当是阿克谢尔.包尔逊跳,也称一周半跳跃,它也可因起跳用刃和是否同足落冰分为很多种类。但最常用的前外刃起跳,后外刃落冰的不同足阿克谢尔跳。下面以此为例进行介绍。
准备动作:右后外刃弧线滑行
起跳用刃:左前外刃
空中转体:540°
落冰用刃:右后外刃
技术要领:准备动作与华尔兹跳相同,左前外刃起跳后需要在空中转体540°,所以要求将两臂在空中抱紧于胸前,浮腿向上摆动后,也应迅速向起跳腿靠拢,目的都是为了缩小转动半径,加快转体速度。此外还要特别注意身体直立,在空中还要完成重心由左起跳腿向右落冰腿的转移动作。在完成540°转体后,应将两臂向两侧迅速打开,左腿向后方伸出,以抵制身体继续转动,完成落冰动作。
身体在空中保持直立,在空中完成重心转移和及时打开双臂是完成阿克谢尔跳的三个主要技术环节。
三、沙霍夫跳(Salchow) TOP
沙霍夫跳也称后内结环跳或后内一周跳。
准备动作:左前外刃“3”字步
起跳用刃:左后内刃
空中转体:360°
落冰用刃:右后外刃
技术要领:左前外刃“3”字步滑行和转体都要平稳,身体要直立,不能左右倾斜或摆动。左后内刃起跳时,左膝深屈,左肩在前,右肩在后,浮足在后,重心在左滑足上。在起跳瞬间,左膝伸直,右浮腿向上摆动和两臂带动上体向左转动等动作应同时进行。在空中身体应保持直立,两臂均得抱在胸前,浮腿靠紧,伸向身体两侧,左浮腿向后滑行方向伸展。完成有后外刃落冰动作。
在做沙霍夫跳时,最常出现的错误是身体在起跳时过分向圆内和向前倾斜,这样就造成起跳时,重心不在左后内刃上。另一个常见的错误是起跳时过分用刀齿,明显地减弱了水平速度,这不仅不利于起跳,更不利于落冰动作的完成。
四、路卜跳(Loop) TOP
路卜跳,也称后外结环跳或后外跳
准备动作:左前外“3”字步或右前内“3”字步
起跳用刃:右后外刃
空中转体:360°
落冰用刃:右后外刃
技术要领:准备阶段的“3”字步转体要平稳。起跳时,右膝深屈,上体直立,左肩在前,右肩在后,身体重心于右后外刃之上。在起跳的瞬间,右膝迅速伸直,左肩向后,右肩向前带动上体向左迅速转体。同时左浮腿向上,用大腿带动小腿。在空中双臂紧抱于胸前,身体保持直立。浮腿紧靠起跳腿,重心仍保持在右起跳腿一侧。在空中完成360°转体后,迅速将两臂打开。左浮腿向后伸,用右后外刃落冰。
路卜跳最常出现错误是:起跳前身体转动过早,造成身体扭曲,不利于起跳。因此在起跳时,上动作要协调地配合是十分重要的。此外还应注意,起跳时不能过分用刀齿制动,这样不利于起跳和落冰。
五、点冰路卜跳(Toe loop) TOP
点冰路卜跳也称后外点冰跳。它与路卜跳不同在于起跳时有点冰动作。
准备动作:有两种方?/div>
花样滑冰运动的基本技术
--单人花样滑冰的基本技术
之旋转动作
双足旋转 单足旋转 换足旋转 联合旋转 跳接旋转
单人滑的旋转动作也是组成一套表演节目的重要技术内容之一。
旋转动作大体可以分为双足旋转、单足旋转、换足旋转、联合旋转和跳接旋转等五大种类。每一种类的旋转又可因旋转足用刃、旋转方向和姿势的不同,而名称也不同。
任何一种旋转动作都由准备动作、旋转用刃、旋转姿势和结束动作等四个步骤所组成。
旋转动作的动力主要来自于在滑行中突然制动,用两臂及双肩摆动方向的不同,以及浮腿浮足的相应配合,带动身体形成一个转动轴心。在旋转中,还可以用收回两臂及浮腿以缩小旋转半径,达到加速旋转的目的。在旋转结束时,可以打开双臂及浮腿,以增大旋转半径,减慢旋转速度。
旋转动作,不仅可以锻炼人的前庭功能和平衡能力,而且千姿百态的旋转十分优美,给一套表演节目增加不少光彩。
做旋转动作时,可因各自的习惯用不同的旋转方向。一般情况,大多数人习惯于向左的逆时针方向旋转,少数选手可能较好地掌握两个方向的旋转。以下以逆时针方向介绍各类旋转。
一、双足旋转 TOP
双足旋转是由两只脚支撑的旋转动作,所以相对容易一些,最常做的双足旋转有以下两种。
1、双足直立旋转
准备动作:初学者可以用原地双足分开站立做准备,掌握后可用左前外“3”字步准备。
旋转用刃:左后内刃和右前内刃
旋转姿势:直立姿势
结束动作:右后外刃或左前外刃弧线滑出
技术要领:初学者可在原地直立,双足分开与肩同宽,左臂向前,右臂向后,双膝微屈。在开始旋转时,左臂带动左肩用力向左后摆动,右臂带动右肩用力向右前摆动,双膝同时迅速伸直,使整个直立的身体形成一个转动的轴心和两个相反的转动力,此时便形成了左后内刃--右前内刃的双足直立旋转。在旋转的最初几圈,两臂应呈对称侧平举姿势,以协助掌握身体平衡和转动轴心。此后可收回两臂,缩小旋转半径,加快旋转速度。在旋转结束时,可以伸开双臂,减缓旋转速度。用右后外刃或左前外刃弧线滑出,结束旋转动作。
在初练双足直立旋转时,保持身体直立,两臂动作均匀对称,是保持旋转轴心的重要环节。初练时不必过早追求旋转速度和圈数,待熟练后,能够控制旋转轴心时,再适当加速。只有姿势正确,才有可能旋转得快,旋转圈数才可能多。
在熟练的基础上,可试着用左前外“3”字步起转。左前外“3”字步达到顶点时,可用刀齿突然制动,此时应迅速将右足放在冰面上,左肩向左后和右肩向右前用力摆动,形成对称性左后内刃--右前内刃双足直立旋转。其它要求同上所述。
左前外“3”字步起转应用普遍,必须很好地掌握,以下介绍的全部旋转几乎都用此“3”字步开始。
双足直立旋转是最简单的旋转,是练习旋转动作的入门技术。技术动作虽不复杂,但通过练习可以找到旋转中如何掌握技巧,把握身体各部位的平衡和姿势,在出现问题时如何调整自己的动作,以保持正确的旋转姿势和旋转轴心。
2、双足直立交叉旋转
准备动作:左前外刃“3”字步
旋转用刃:左前外刃和右后外刃
旋转姿势:身体直立,双腿及双足在身前呈交叉状,左腿在前,左足在右足前外侧,足尖靠近
结束动作:右后外刃或左前外刃滑出
技术要领:这种旋转虽属双足类旋转,但由于双叉故技术难度较高。初练时应从双足直立转开始,旋转2至3圈后,左足经右足前方,顺应旋转方向滑至右足前外侧,形成双腿及双叉姿势,用右后外刃和左前内刃形成对称的双叉旋转姿势,足尖应靠近,足跟分开。
在练习中,必须注意在形成交叉旋转后,身体重心必须保持在双足中间,即双足着力要均匀对称,身体保持直立,才能旋转顺利流畅。否则,双足用力不均,身体重心也会变化,会出现一只冰刃严重刮冰现象,造成旋转失误,甚至可能跌倒。
在熟练后,也可以用左前外刃“3”字步起转后,将右足经左足后方放到冰面上,形成双足直立交叉旋转姿势。这种方法较难掌握。
二、单足旋转 TOP
从广义上分类,凡用一只冰刀在冰上进行旋转的动作都属于单足旋转类。所以单足旋转可因旋转用刃和姿势的不同分为很多种类。例如,单足直立旋转、弓身旋转、蹲踞旋转和燕式旋转等。
单足旋转支撑点在一只脚上,所以难度也大一些。此外再加上多种姿势变化,旋转的技术难点各不相同。下面分别进行介绍。
1、单足直立旋转
准备动作:左前外--右后内刃“3”字步
旋转用刃:左后内刃
结束动作:右后外刃或左前外刃滑出
技术要领:用左前外刃“3”字步起转,刀齿制动后开始旋转,两臂的动作同双足直立旋转。唯左足呈后?/div>
花样滑冰运动的基本技术
--单人花样滑冰的基本技术
之自由滑动作
燕式平衡动作 大一字滑行 弓箭步滑行 规 尺 阿拉贝斯
所谓自由滑动作是指那些除滑行技术、步法、跳跃和旋转等动作之外的起陪衬和表演作用一系列自由滑行技术动作。单人自由滑动种类很多,这里只介绍一些常用的和比较规范的一些自由滑动作。
一、燕式平衡动作 TOP
燕式平衡动作是一种身体前屈,一条腿抬起,两臂自然伸展和另一条腿在冰上的滑行动作,因形似燕子,故得此名。
燕式平衡动作可因滑行用刃和方向的不同,可大致分为以下数种类型:
1、左前外刃燕式平衡
2、右前外刃燕式平衡
3、左前内刃燕式平衡
4、右前内刃燕式平衡
5、左后外刃燕式平衡
6、右后外刃燕式平衡
7、左后内刃燕式平衡
8、右后内刃燕式平衡
各种燕式平衡动作并不难作,但做好也不容易。主要是动作要自然舒展。两臂和浮腿的位置要正确,上体和浮腿应抬得稍高一些,姿势要优美,两臂可以根据表演的需要做些舞蹈动作,可以仰头,一只手可以扶腿或提刀。
上述各种燕式平衡动作,可以在表演中改变滑行方向和用刃,共同构成一组多变的燕式组合动作,例如左前外燕式平衡,转“3”字后变为左后内燕式平衡,或转“3”后换足为右后外燕式平衡等等。这种变化做得越巧妙,动作就更新颖、优美和富于创造性。
燕式平衡动作实质上是基本滑行技术的延伸,由于增加了姿势变化,其动作难度和美感也大为增加,它已构成女选手艺术表演中不可缺少的技术动作之一。
二、大一字滑行 TOP
大一字滑行是将两腿分开沿一定方向成直线或弧线的双足滑行动作,它也因用刃和滑行方向等不同而分为许多种类。
1、左前外--右后外大一字滑行
2、右前外--左后外大一字滑行
3、左前内--右后内大一字滑行
4、右前内--左后内大一字滑行
做外刃大一字滑行时,身体向后倾,重心在背侧,足尖向外分开,足跟相对,保持适当距离,成弧线滑行。
做内刃大一字滑行时,身体向前倾,重心在腹侧。
大一字滑行是在获得一定速度后进行表演的滑行动作。在滑行中两臂的姿势可以自由,也可以做些舞蹈动作。
三、弓箭步滑行 TOP
弓箭步滑行也称艾娜.包尔滑行(由艾娜.包尔首创)。它是一种一条滑腿屈曲,另一滑腿伸直,成弓箭步姿势的一种双足滑行动作。
弓箭步滑行用刃比较复杂,姿势变化也较多。上体可以前倾或后仰,两臂可以做些舞蹈动作。滑行方向变化较多,它实质上是一种大一字步的发展和延伸,并多被女选手所选用,配以多变的舞蹈姿势,动作十分优美抒情,它也是一种在获得足够滑行速度后才能进行表演的自由滑动作。
四、规尺 TOP
规尺动作是利用一只刀齿或刀跟点冰,另一只冰刀围绕其滑行的类似圆规的动作。它也可以因点冰和滑行足以及用刃的不同而分为许多种类。
1、左前外规尺(右刀齿点冰)
2、右前外规尺(左刀齿点冰)
3、左前内规尺(右刀齿或刀跟点冰)
4、右前内规尺(左刀齿或刀跟点冰)
5、左后外规尺(左刀齿点冰)
6、右后外规尺(左刀齿点冰)
7、左后内规尺(右刀齿或刀跟点冰)
8、右后内规尺(左刀齿或刀跟点冰)
在做规尺动作时,无论是用刀齿还是刀跟点冰,另一只滑行足必须与所滑圆半径相垂直的方向滑行。做规尺滑行时,上体和两臂的位置姿势是自由的,可根据表演需要进行安排。
规尺滑行虽然有一只冰刀在动,但另一只冰刀为固定圆心,所以规尺动作属原地滑行动作,故在一整套表演中不宜出现过多,一般安排在段落或表演结束时。
五、阿拉贝斯 TOP
阿拉贝斯是一种舞蹈动作的名称,用阿接贝斯姿势在冰上滑行是一种很优美的动作,这种滑行也可因滑行用刃和滑行方向的不同而分为许多种类型。
1、左前外刃阿拉贝斯滑行
2、右前外刃阿拉贝斯滑行
3、左前内刃阿拉贝斯滑行
4、右前内刃阿拉贝斯滑行
5、左后外刃阿拉贝斯滑行
6、右后外刃阿拉贝斯滑行
7、左后内刃阿拉贝斯滑行
8、右后内刃阿拉贝斯滑行
阿拉贝斯滑行在一套表演中应用广泛,由于滑行方向多变,两臂和浮腿姿势多样,滑行用刃不同,以及多种阿拉贝斯滑行动作协调组合,不仅动作十分优美,而且千姿百态的表演会增加表演的效果和艺术感染力。

The lighter drive 更轻便的驾驶理念
Electric cars made from carbon fibre will be safer and go farther
电瓶汽车+碳纤维材料=安全,耐用
They look safe in thereMARK WEBBER has a lot to thank tiny strands of carbon for. When his Formula 1 car cartwheeled in a spectacular 306kph (190mph) crash at the recent Valencia Grand Prix, what helped him to escape unscathed was the immensely strong carbon-fibre “tub” that racing drivers now sit in. Carbon fibre is an expensive alternative to making things in steel or aluminium, but besides being extremely strong it is also very light. It is found in high-performance parts, like aircraft wings, bits of supercars and the frames of pricey mountain bikes. But if work by Germany’s BMW proves successful, it could also become the material of choice to mass-produce electric cars.
6月,F1瓦伦西亚大奖赛发生了惊人一幕:以每小时306公里(190英里)行驶在赛道上的马克?6?1韦伯发生了严重的翻车事故。奇迹的是,韦伯本人毫发无 伤。奥妙之处就在于当下流行于F1的——碳纤维底座。虽然与铁,铝相比,它的造价较高,但是抗压及轻便性都远远好于铁和铝。目前,炭纤维材料还大多使用在 高精度领域,如飞机机翼,F1赛车,或是私人山地车等。不过这一传统观念可能会被宝马公司打破,一旦试验成功,那么碳纤维就可以率先广泛应用在电动汽车领 域。
The Barian carmaker plans to launch a new plug-in electric car in 2013. It will be one of the first designed from scratch to use an electric motor rather than being converted from an existing model. Reducing the weight of this four-seater car, known as the Megacity concept, will be crucial to improving its performance and range. So BMW is planning to use no steel at all. The Megacity will be built as two modules: an aluminium chassis will contain the electric drive-system and battery, and a body made almost entirely of carbon fibre will be fitted onto it.
德国汽车制造商正将在2013年推出一款电瓶可拆卸式环保车。这并不是从现有车型改装而来,而是设计师卧薪尝胆的一次全新尝试。更轻便的4人坐驾,完 全符合现代城市环保理念,这款“无铁”车型的设计,彰显出了它的与众不同与理念上的更新换代。但是这样一个设想目前还处在起步阶段,或许成功的那天,汽车 铝制底盘上充电驾驶装置与设备,及全身碳纤维的设计工艺,能够更好的诠释大城市的环保概念。
Carbon fibre is 30% lighter than aluminium and 50% lighter than steel. The fibres are extremely tear-resistant. When woven into a lattice structure and impregnated with resin they can produce a part that is stronger than steel. The trouble is the process is labour-intensive and slow, not least because components may he to be cured for hours under pressure in massive ovens called autocles. For carmakers, used to stamping out steel body-parts in a few seconds, this has ruled out carbon fibre for high-volume production. BMW, however, aims to change that.
碳纤维比铝轻便30%,是铁的50%。同时,由于纤维具有极强的抗断裂性,再融入树脂形成晶体结构后,那么它的强度就要超过铁。但是这道工序属于劳动密集 型,效率相对较低,以前车用铁制品的切割仅需要几秒钟时间就能完成,而现在则需要在高压炉内高温锻造几个小时,因此,大量生产碳纤维的可能性不高。不过, 宝马公司目前也正在试图改变这一情况。
Its production line starts with a so-called precursor: a fibre spun from a polymer. This is carbonised by heating it in multiple stages to lee individual carbon fibres just seven microns (0.007 millimetres) thick. Around 50,000 of these fibres are bundled together into a yarn which is then made into a fabric. This can be cut and handled like a textile. Strips of fabric are then overlaid to align their fibres in such a way to maximise their load-bearing characteristics as required—in effect tailoring components like a bespoke suit.
现在,宝马生产线守开先河,将聚合体加工成纤维状,这个碳化过程需要在高温下进行几道工序,最后产生的碳纤维厚度只有7微米(0.007毫米)。然后,大 概将5000根这样的纤维拧成一股就成了纤维织物,再将这样的纤维根据它的陌生能力将它切割成最合适的尺寸,实际上,这个步骤与量体裁衣有异曲同工之妙。
Along come the robots 自动机将助一臂之力
BMW uses molds, heat and pressure to produce contours in the fabric. Resin is then injected into the molds to bond the fibres together. How the resin flows through the fibres is crucial; it has to be done quickly and lee no area untreated before it starts to cure. A release agent in the resin migrates to the surface to prevent the component sticking in the mold. The whole process, which can be handled by robots, is completed in minutes.
然后,再利用模具与高温将纤维织物打造成型。首先,将树脂注入模具粘合纤维,这里有两个细节非常关键,一是动作要快不能拖泥带水,二是在没有粘合之前确保 模具内的树脂流向均匀。树脂中混有的隔离剂此时发挥功效,避免了纤维与模具发生粘连。整道工序,在自动仪器的协助下,仅需几分钟便可完成。
The resulting carbon-fibre parts are bonded together to construct the body of the car. Besides their lightness, BMW’s experimental vehicles he exceeded expectations in crash tests, says the company. During front- and rear-impact-tests the aluminium chassis crumples to absorb energy, but lees the rigid carbon-fibre passenger compartment intact. Even extreme side-impacts protected the crash dummies and the battery (automatically switched off when the airbags trigger). In many cases crash damage is reparable by cutting out broken sections of carbon fibre and bonding in new ones.
此时的碳纤维就可以应用于汽车制造。宝马公司声称:除了超轻便的特性之外,碳纤维的抗挤压能力也令人惊叹。在对车头车尾抗冲击测试中发现,一方面是铝制底 盘受到挤压而变形,缓冲了部分能量,而坚硬的碳纤维能够保证车身安然无恙。即使是侧面来的强力冲击,也能够有效保护车厢内人模型及电瓶毫发无伤(当然, 气囊装置启动电瓶能够自动断电)。即便是车身有所受损,也不用担心,切割掉受损部分再粘合上新部件,完全可以让车体恢复原状。
At some point, however, carbon-fibre cars will be scred. Steel and aluminium is easy to recycle, but carbon fibre is tricky. Carmakers are working with aerospace firms on ways to do it. BMW has pioneered a process to reuse offcuts by breaking them up with heat to turn them back into raw material. This can be used to make composites with about half the strength of new carbon fibre.
铝的回收再利用技术已经非常成熟,但是从某角度来说,碳纤维这方面的技术还有待研究。目前,制造商正和宇宙空间机构合作,试图填补这一空白。眼下,处理碳 纤维“边脚料”最先进的方法还是来自宝马公司,他们通过高温分解,能够使之退回成未加工状态。通过此种方法生产出的复合材料也具有碳纤维一半的硬度。
Another advantage of a carbon-fibre body is that it will not corrode. So, apart from the battery wearing out in ten years or so, electric cars could last for decades (electric motors need little servicing). This will make it even harder for car designers to persuade those driving electrically to trade in their rustless, tough-as-old-boots vehicles for a new model.
碳纤维的另一优势在于不易腐蚀,如果不考虑电瓶10年左右的使用寿命,这种碳纤维电瓶汽车可以使用长达几十年(当然马达还是需要检修的)。与结实耐穿的靴 子让人不忍丢弃一样,当设计理念再有突飞猛进的发展时,如何让使用者放弃碳纤维电瓶汽车,设计者可要好好动一番脑筋喽。

亚马逊:做 游戏 的“定义者”,而不仅仅是“玩家”
文/王子威@零售威观察
?在商场中,比对手玩得更好确实可以在竞争中占据先机,可是如果你能改变规则,让竞争对手和你在你的世界中玩,那就真的是赢家了。
2005年,亚马逊在投行的一片嘲讽中“大张旗鼓地”改变了 游戏 规则——它推出了Amazon Prime,并提出了“2日免费送达”这个明显不知天高地厚的“提议”。很多年以后,其他零售商才意识到“灾难来临”,开始应对这场来自付费会员体系的浪潮,而亚马逊也在这期间成为北美最大的电商,并跻身全球最大电商市场的行列当中。
?于此同时,两日免费送达,也成了整个零售行业的“新标准”。
在过去的几年中,一些传统零售商也迎头追击,在电商、全渠道等领域投入巨资,希望能挑战Amazon Prime的地位。
我们不妨先来看看亚马逊的两大死敌,沃尔玛(Walmart)和塔吉特超市(Target)。
?
2016年,沃尔玛以33亿美元收购了电商平台Jet,并将其首席执行官Marc Lore收入麾下,在电商和物流领域进行转型,目前也取得了相当不错的进展:
尽管这些投资在短期内可能带来利润的降低,不过长期看是值得的,在今年2季度,沃尔玛美国的同比销售增长2.8%,电商业务的营收增长37%。
通过Cartwheel这个APP,塔吉特早已经开始将消费者的店内体验实现数字化了,后来这个APP也成为了塔吉特的官方APP,为消费者提供无缝的全渠道体验。
2017年12月,塔吉特收购了Shipt,这给塔吉特带来了一场全新的变革,让塔吉特的购物体验再上一层楼。
塔吉特在2019年的一些亮点还包括:
从今年的2季报看,塔吉特的努力得到了回报,同比销售增长3.4%,电商渠道的销售也增加34%。
有趣的是,亚马逊没对此做出任何回应,而是继续加快自己的步伐,因为在亚马逊的眼中,各大竞争对手更像是在应对亚马逊从2005年就开始干的事儿。
近几年来,一直微利的亚马逊终于产生了漂亮的利润数据,这可以说是2005年开启“第二曲线”之后取得成功的标志,于是亚马逊似乎又打算开启新一个“第二曲线”了,因为它又开始把利润丢到各类新项目进行测试、调整和迭代,以撬动下一个飞轮增长周期——换句话说,亚马逊又打算再定义一次 游戏 规则了。
以下这些就是亚马逊开始投资的领域了:
免费一日送达与加速同日送达
亚马逊宣布对超过1000万种商品实现全美免费1日送达,并在部分大都市实现300万种商品的同日送达——这一切,亚马逊已经通过电视广告、网络广告、户外广告等方式“通电全美”了。
亚马逊已经把大部分的利润都再投资到了中程(Middle-Mile)和最后一公里基础设施建造、合作、收购上,以扩大其规模、提升效率并降低成本。
?
附加品和“Prime独享产品”消失
亚马逊曾经搞出很多价格低廉、利润极低的“附加品(Add-On)”,这样,消费者不得不为了这些产品而买一大堆其他的,以凑出25美元的最低消费;同时,亚马逊还有不少仅供Prime会员购买的“Prime独享产品”。这些本身都是为利润服务的套路。
然而,在过去的半年多时间,随着亚马逊重新定义自己的增长模型,以与沃尔玛、塔吉特们PK,此类产品几乎完全消失了。
Prime Pantry成为Prime服务的附加价值
本身,亚马逊在Prime服务之外,还有一个Prime Pantry服务,其本质是扩大低价、小包装食品和快消品的种类,并鼓励消费者大批量购买。对于所有Prime会员来说,每月可以额外支付5美元来获得Prime Pantry的免费配送。
现在,Prime Pantry被免费整合进了Prime服务当中,只要求单笔订单大于35美元就可以免费配送,并且当消费者大批量购买时就给与更大折扣(例如买15件,则额外减15美元等),通过低障碍、少摩擦的方式来提升消费者购物篮中商品数量,进而从消费者的钱包中抢占更多份额。
?
注意力之战
据Reelgood在2019年最新的一项研究,Prime Video在可观看**和节目数量以及高质量的**数量上超过了它的竞争对手Netflix和Hulu——亚马逊目前只是在高质量节目的数量上落后。
?
? 简化退货政策
根据Avionos在2019年的消费者调查,50%的受访者将“简单的退货政策”视为一个积极的体验。于是,亚马逊就改进了自己的退货政策,在亚马逊书店(Amazon Books)、四星店(Amazon 4-Star)、全食超市(Whole Foods)、科尔氏百货(Kohl's)和UPS店中提供“免费的无箱退货”(在其他的地方也可以免费退货,但是需要带着箱子)。
生鲜杂货配送
尽管亚马逊生鲜(Amazon Fresh)的扩张已经落后于Prime Now服务(目前覆盖超过88个城市),但是它的扩张依然在继续。亚马逊正在美国推进一项新的,旨在于开设新的连锁杂货店,目前已经在洛杉矶签署了多份租约,并在中期将业务扩展到其他大都市。
亚马逊的目光已经投向了生鲜杂货领域,未来将基于既有的基础设施来加速扩张。
