煞车

The principle of braking is simple: slowing an object by removing kinetic energy from it. Formula One cars have disc brakes (like most road-cars) with rotating discs being squeezed between two brake pads by the action of a hydraulic calliper.

煞车系统的目的很简单，将动能转移来减慢物体的速度。F1赛车使用碟盘刹车(就像大多数的市售车一样)，有转动的碟盘，以液压方式由卡钳推动两片煞车片夹压煞车碟来减速。

I clearly remember one warm 28 degree day in LA when I was driving my Mustang Fastback that didn't have power windows, power steering, power brakes, GPRS satellite navigation, air conditioning, cup holders, xenon lights, or bluetooth in-car telephone systems, etc… Yes, the brakes and steering were hard to operate and my face and back were wet with sweat but the sensation and indescribable high I got from driving the car down the highway was something you'd never experience from driving a modern sedan or sports car.

我清楚记得一个在洛城的日子，户外温度大约摄氏28度，我开著一辆揭背式野马。那辆车没有电动窗，没有动力方向盘，没有动力辅助煞车，没有GPRS卫星导航系统，没有冷气空调，没有杯座，没有氙气车灯，没有内装蓝牙电话系统…等等。煞车跟方向盘都很难控制，我的脸和背布满了汗珠，但是当我开上快速道路时，我内心兴高采烈的程度是你在现代的轿车或跑车身上完全无法体验得到的。

The brake power is above 60﹪ of the weight of car and the hand-brake power is above 20﹪ of the weight of car. So the check effect is also O.K.

煞车力是车辆重的60﹪以上，手煞车力是车辆重的20﹪以上，所以检验结果也是合格的。

So I might be of the brake when I come over the ledge and on the brake on this rock when I get some good traction and then and then off when the traction is a kind of loose, and definitely off the brake when I come down at this corner and I going to make a direction change, so my front wheel can roll fluently with traction.

这里有土会让煞前煞时打滑不过这个石头可提供煞车抓力，所以当我过岩石时我会放掉煞车，然后上这个石头有比较好的抓地力后再刹车，然后当抓地力减弱时再放掉煞车，我下这个转角一定放掉煞车而且我要转弯，所以我前轮可以流畅的滚过且能抓地。

Here is some dirt that is pretty slippery to get on the front brake hard in these places but for instance here is a rock that is going to provide good traction.

Besides, the rear wheel of the walker is equipped with the electro- magnetic brake which can be triggered by the controller and therefore lock the rear wheel when the speed of the walker is too high.

并在助行器的后轮上装有电磁煞车，当助行器的速度过快时，控制器送出讯号启动电磁煞车将后轮锁住，以避免使用者发生危险。

The development intends to apply the light metal aluminum alloy to replace the original ferrous-based braking and crossmember parts via innovative methodologies, such as product lightweight design, structural stress analysis, light metal manufacturing process and prototype fabrication, to reduce the weight of braking and steering parts on the chaises system.

本技术是经由创新设计以轻量化材料-铝合金取代原有之铸铁煞车碟片及钢板冲压焊接之横梁，从产品轻量化设计、结构应力分析、制造工程及雏型件制作，进行工程整合，达到底盘煞车/转向结构系统之轻量化之目的。

For an instant your chest will be so far back that it might hit the seat, immediately start pulling yourself back to more normal stance as you land, another strategy for dropping off the ledge is with speed.As you hip a lip lift the front wheel, you need to be off the brakes as you come off the leap and have enough momentum to land rear wheel first.

另一种下陡降坡的技巧是用速度，当你遇到断层时抬前轮，一过那个断层时放开煞车然后有足够空间让你后轮先著地，找个平滑的著地点很重要而且要有足够空间来煞车避开障碍物。

The method worked quite well, there was not much damage on the plastic, and the acrylic paint and lacquer primer are all gone.

这方法不错，珐琅油层被煞车油浸得剥落了，水性油层则被煞车油溶解了；而塑胶的质地只轻微变弱，没有出现严重爆胶的情况。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
