The strength and modulus of elasticity of matrix increase from almost zero, then at a certain age up to those of the coarse aggregate, and even exceed for lightweight concrete.
基体的强度和弹性模量从零开始增加，到一定龄期后接近集料分散相，对于轻集料混凝土，基体的强度和刚度在一定龄期还将超过集料分散相。
In the other, we use the particular attributes of zero-crossings as constraint in coarse matching, which can improve the matching speed.
另一方面，使用过零点的特有属性作为粗匹配的匹配约束，可以提高匹配速度。
A new scheme for optimization of coarse wavelength-division-multiplexing (CWDM) system based on directly modulated lasers (DMLs) and non-zero dispersion shifted fibers (NZDSF) is proposed.
利用光通信系统设计平台，研究了一种基于直接调制激光器和非零色散位移光纤(NZDSF)的高速粗波分复用(CWDM)系统的优化方案。
