The next major milestone for the ARH program is the Limited User Test or LUT. This milestone will evaluate how well the ARH-70A meets the program requirements.
ARH项目的下一个里程碑是有限用户测试(LUT)，旨在评估arh - 70 A如何满足项目需求。
The ARH change laws of concrete with water to binder ratio lower than 0.4 can be expressed with a non-linear equation.
水胶比小于0.4的混凝土其自身相对湿度变化规律可用非线性方程表征。
The reduction of ARH varies also with the different influences on the ratio and process of hydration of concrete with different mineral blends.
不同矿物掺合料因对混凝土水化进程与速率的影响不同，ARH下降也不同。
