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.
