贴士：将蛋糕出模后，可以在表面洒上一些糖霜做装饰。

Tip: Turn the cake upside down out of the tin to serve. You could dust it with some icing sugar if you like.

该模具结构不但解决了倒u形弯曲件出模困难问题，而且模具的可靠性、安全性及使用寿命显著提高。

The structure can make the back U-type bent part stripped effectively, and also increase the reliability, safety and service life of the die.

加强水平和垂直度监控，控制筒身倾斜及扭转；加强出模混凝土的收光和养护，保证出模混凝土的质量。

By monitoring the level and vertical degree, and controlling the tube not to slope and rotate, it guarantees the quality of the concrete out of formwork in terms of the maintenance.

If you give me a pair of numbers, Ax and Ay, that's as good as giving me this arrow, because I can find the length of the arrow by Pythagoras' theorem.

如果给我一组数字,Ax 和 Ay,就相当于给了我这个箭头示意图,因为我可以利用毕达哥拉斯定理定理求出模长

We know it's going around in a circle because if I find the length of this vector, which is the x-square part, plus the y-square part, I just get r square at all times, because sine square plus cosine square is one.

我们之所以知道它做圆周运动,是因为我求出了这个矢量的模长,也就是 x 的平方加上 y 的平方,我就得到了它在任意时刻的模长平方,因为正弦平方加余弦平方始终等于1
