At the same time, a new kind of pushing graphite boat was designed for the sake of meeting the needs of the experiment.

同时，为了满足实验的需要，设计了一种新型推拉式石墨舟。

To solve this problem, we modify the graphite boat, which is from traditional horizontal sliding graphite boat to rotatable graphite boat.

为了解决这个问题，我们对石墨舟做了改进：由传统的水平滑动石墨舟改为可旋转石墨舟。

Such small tolerances require careful design and machining of the graphite boat and slider so that the sliding motion is smooth and without jitter.

这样小的公差要求仔细设计和精心加工石墨舟皿和滑动器，从而使滑动器的滑动平滑而没有跳动。
