fragile material

基本解释

In each case the fragile material could be destroyed at every step.
脆弱的样本在每个操作步骤中都有可以被毁坏，因此我们必须非常小心谨慎。
A smart ultrasonic generator was investigated for rotary ultrasonic machining of hard, fragile material.
为进行硬脆材料的旋转超声加工，研制了智能超声波发生器。
Therefore we point out a new method of testing fragile material's strength of extension. That is to say we can measure the disk's strength of extension by pressing in its diametric.
从而对脆性材料抗拉强度的测定提出了一种新的方法，即通过对圆盘沿直径对心受压试验可测出其抗拉强度。

This is a very fragile material so it is important to discuss an integrated approach on how to deal with the conservation because this material continues to be used even today in modern construction.
