The characteristic equation of orbital angular momentum modes in a ring fiber is derived. By solving the equation with the graphical method, mode distribution in a ring fiber can be precisely determined for arbitrary fiber parameters without relying on simulation of the vector field. This will provide a useful method to determine the separation between quasi-degenerate modes in a ring fiber.

美国国家航空和航天局在阿伯丁试验场的试验中，在核泵浦激光器获得了一千瓦的输出后，已停止了该激光器的工作。据该计划的负责人伦道夫（L. P. Randoeph)说，用脉冲反应堆所做的试验表明,核泵浦有很大的潜力。但下一步的研究计划需有特殊的反应堆，该局目前却无能为力。为了避开预算上的限制，在马歇尔空间飞行中心进行激光推进试验中,该局使用了陆军的一台多余的高能激光器，它是70年代中期装在坦克上的陆军机动试验装置中的试验系统。
在前月的一项联合通告中，美帝国家航空与宇宙航行局和美帝无线电公司描述了该局所作的在地空卫星跟踪和通讯实验中釆用该公司制作的10瓦电离氩激光器的计划。也可能用公司制造的激光器确定用激光束作为ESSA之类的气象卫星等空间飞行器摄取地上夜间照片的定位(或参考)信标的可能性。

通过进行工艺参数(激光功率、扫描速度和送粉速率)可控的单道激光熔覆实验，观察了沉积轨迹横截面形貌的变化；提出了单一参数（δ参数，δ=wtan β/2h）控制的横截面形貌曲线方程。根据横截面几何特征参数：沉积轨迹宽度w、高度h、面积F和沉积角β的测量数据，用回归处理方法，给出了δ参数与横截面名义面积Fm（Fm=wh）之间的函数关系，得到了横截面形貌随Fm的变化规律；同时用F和β的测量数据验证了横截面形貌曲线方程。
