The contact problem between the infinite semicircle cylinder and the plane is a typical example in the field of contact problem research. The solutions obtained through static model are compared with the Hertzian solutions in this paper.

以无限长半圆柱与水平面间的接触问题为算例，本文将静力学计算结果与经典Hertz接触理论解比较，获得了良好的一致；在动力学方面，本文仿真了突然加载下的半圆柱与水平面的接触过程，仿真收敛性良好。

Or heat-pipe evacuated collector tubes with a flat absorber and a semicylindric absorber , relative solar irradiance changing with incident angles on various points of absorber s have been measured respectively by using a solar simulator.

以太阳模拟器为光源，对平面吸热板和半圆柱吸热板热管式真空集热管测定了玻璃罩管内吸热板表面各点随光线入射角变化的相对太阳辐照强度分布，给出了平面与半圆柱吸热板平均相对太阳辐照强度随人射角变化的规律及三维拟合公式，并对两种情况的实验结果进行了初步分析。

A compound structure—Double Half-cylindrical Lens is proposed firstly by the author.

双半圆柱透镜是作者首次提出的一种复合结构柱透镜，它突破了普通圆柱透镜在最佳准直时对透镜材料折射率必须小于2的限制，在透镜材料大于2甚至更高的条件下，其准直能力大大提高，准直效果在理论上可达0.1mrad。
