1·Trial method of shaped steel axial compression members is analyzed in this paper.
分析了型钢轴压构件在试算法中的运用。
2·We use the scientific computational lan guage MATLAB to program and calculate the shaped steel columns via man -machine conversation, and quickly obtain correct results of design.
应用科学计算语言MATLAB编程，在人机交互下计算型钢压杆，迅速得到正确的设计结果。
3·The electrical heating tube is made of U shaped steel tube, sintered magnesia and heating wire. It is immersed directly in the water for preventing heat loss.
电热管用U型钢管，烧结氧化镁和电热丝制成，直接浸在水里热能损耗少。
