影响激光加热运动圆柱体的加热线型的分析

 采用几何分析的方法研究激光加热运动圆柱体的过程，在说明加热线型的概念和意义后，讨论了在地平面上各点处所具有的加热线型的时间宽度，从而指出，为了激光有效加热运动圆柱体，激光器应当怎样在地平面上放置的原则。即根据激光器有效工作时间与圆柱体抛射时间的比例关系选择一定的相对时间宽度等值线，以此等值线为界在地平面上划出一有效区域，并从中选取距离轨道最近的点作为激光器的放置点。当考虑大气对激光的衰减作用时，激光以小于一定入射角阈值进行动态加热的总能量将出现极大值，在此处放置激光器最有利于动态加热。

Effect of heating configuration on laser heating of flying cylinder

The laser heating process of flying cylinder is discussed by means of geometry analysis.The meaning of heating configuration is defined and explained,the significance of this item in describing effective heating of the flying cylinder is pointed out.The distribution of the time width of heating configuration in the space above the ground is also discussed.The rules of locating the laser setup for effective heating of the flying cylinder are summarized.Selecting certain relative time width isoline according to the ratio between the laser's effective operation time and the flying time of the cylinder,and determining an effective area on the ground using the isoline as the boundary,the laser can be set on the point closest to the trajectory in the area.The dynamic heating has a maximum total energy when the incident angle of the laser is below a threshold considering the decay of the laser in air.
