Now, if I rotate, the the slope sort of increases, increases, increases, and it becomes the largest when I'm going in the direction of a gradient.

如果旋转的话，那么斜率会变大，变大，变大，当和梯度方向一致时，它达到最大值。

If the length of melted zone is thought invariable for a given kind of alloy, the temperature gradient increases with the rising of the EB power and zone melting rate.

在不考虑熔区长度不变的条件下，固液界面前沿的温度梯度随抽拉速率的增加而增加。
