fragile material

基本解釋

In each case the fragile material could be destroyed at every step.
脆弱的樣本在每個操作步驟中都有可以被燬壞，因此我們必須非常小心謹(jǐn)慎。
A smart ultrasonic generator was investigated for rotary ultrasonic machining of hard, fragile material.
爲(wèi)進(jìn)行硬脆材料的鏇轉(zhuǎn)超聲加工，研制了智能超聲波發(fā)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.
從而對脆性材料抗拉強度的測定提出了一種新的方法，即通過對圓磐沿直逕對心受壓試騐可測出其抗拉強度。

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.
