FGMs的音标

Results showed that W/ Cu FGMs sustained the mechanical integrity after 200 to 700 times of cyclic heat loads with 100~ 400 MW/ m 2 power density and 4 ms pulse width.

结果表明：在100～400MW/m2的瞬时（脉冲宽度为4ms）热负荷作用下，经过200～700次热循环，未发现W/Cu复合体的开裂。

When the temperature dependency of the material properties is considered, the maximum compressive and tensile stresses are 39.6% and 48.9% less than those of the FGMs with constant material properties, respectively.

考虑变物性时的最大拉应力比常物性减小48.9%，最大压应力减小39.6%；

The introduction of the equivalent flexural rigidity provides a new approach for the compositional distribution and structure design of FGMs beyond thermal stress relaxing type such as high high load-bearing capacity FGMs.

等效抗弯刚度的提出为高承载FGM等热应力缓和以外的梯度功能材料的组成分布和结构设计提供了一条新途径。
