In this method, Poisson's ratio, the compressive strength and a suitablestrength theory are needed to calculate the tensile strength of rock material.
与传统测试方法不同,这种方法需要知道材料的泊松比和抗压强度,以及适合于岩石材料的强度理论。

Shaving board adhesive consists of mixed modified waste liquid and UF resins. Proper process can make the shaving board be of suitablestrength and property density.
Through study on human active material Hydroxyapatite, it is regarded as the ideal human's bone replacement material with good characteristics of lower price, biology and suitablestrength.
