During the total solar eclipse in 1919 , scientists verified that light from remote stars could be bent by the gravity of the sun - just as einstein predicted . einstein became world famous overnight 1919年，当日食观测队藉日全食时证实来自遥远恒星的光线被太阳的重力所偏折恰如爱因斯坦的预测一样，一夜之间，爱因斯坦成为全世界的知名人物。
The results show that laser beam far field intensity deflect to the wave length increasing direction about 0 . 2m ~ 0 . 3m when beam pass through flow field and propagate 1km in static atmosphere . high - power laser beam will have thermal booming effect when it pass through gas flow field 研究表明由于流场中存在强的激波结构，使得激光束远场强度分布向光程增大的方向发生了强的偏折，在光束通过流场在标准大气中传播1km后，偏折达到0 . 2m 0 . 3m 。
The results show : laser beam far field intensity distribution deflect to the wave length increasing direction , the influence to laser beam far field intensity distribution of different inflow mach number is little than the influence of different inflow pressure ; flow field has more aberration to 1 . 315um laser beam than to 10 . 6um laser beam 研究表明激光束远场强度分布都向流场光程增大的方向偏折，喷流出口马赫数的变化对激光束远场强度分布的影响较小，喷流出口压力的变化对激光束远场强度分布的影响较强；在相同的流场结构下，流场对波长1 . 315 m激光束的干扰要明显强于对波长10 . 6 m激光束的干扰。
Some results of these experiments are shown as follows : in this paper , the orograpic effects of small islands on tc is firstly revealed . comparing results of experiment b to experiment nb ' s , we find that the terrain of zhoushan archipelago can leads the west - moving tc to deflect southward up to 15 km , and weakens it 本文首次研究了小型岛屿地形对热带气旋的影响，试验b和试验bnz的对比研究发现，舟山群岛的存在能使西行的热带气旋向南偏折，最大可达15公里左右；地形作用还能加速热带气旋强度的减弱。
Considering the contribution of other factors , to improve design accuracy , avoid optical path deviation , reduce insert dissipation and increase the manipuility of the device is our purpose . the simplest type of flat - plate achromatic optical phase retarders is made from a single birefringence material 实践证明，理想的消色差波片应当以简便片状双折射型设计为主，在此基础上考虑其他方面因素的影响，提高其设计精度，避免光路系统偏折，降低插入损耗，从而提高器件的可操作性。
