The effect of water content upon strength and creep characteristic are studied it shows that instantaneous strength decreases with increasing of water content.

通过测定试样含水率，研究含水率对红层软岩强度和蠕变特性的影响。

It was also found that higher concentration of rosin in flux is beneficial for shear creep resistance of the joints, while its effect on the instantaneous shear strength is less obvious.

焊剂中较高的松香浓度明显有益于焊点的抗剪切蠕变强度，而对瞬时剪切强度影响不大。

It is indicated that the spall strength equations determined by the traditional methodology are valid only for the numerically simulated 'pullback' by a local instantaneous critical stress criterion.

研究指出，传统方法确定的层裂强度测定方程仅仅可能对采用瞬时层裂准则得到的数值模拟的层裂信号有效。
