射线角 meaning in Chinese

ray angle

The lifetime of the first excitation state of 64cu on the same experiment published was i = 22 ? 9ps and t = 29 . 8 ? . 4ps respectively . multipole mixing ratio ( 8 ) of the first excitation state of 64cu , that p . w . green had studied through the angular distributions of de - excitation y rays following the 64ni ( p , ny ) reaction was determined to be s = 0 . 12 ? . 04
至于多极混合比，在1976年pwgreen等人同样利用以nio ， fly ）反应，通过退激y射线角分布测量，给出了时cll第一激发态的多极混合比为： 6二0l士0刀4 。
The results show that the study on transimittivity can be done using the points along the circle arc centered at the roadway or the boring core , the transimittivity at the joints along the right angle ray can be studied using one single point behind the joint , and the studies on transimittivity can be done on any reasonable radius value of the roadway or boring core in a typical rock
分析结果表明：单节理后各节点透射率的研究，可以通过单节理后某一以巷道或钻孔中心为中心的圆弧上各节点的透射率来展开；射线角为90的射线上节理后各节点透射率的研究，可以通过节理后某一节点的透射率来展开；单节理的透射率的研究可以在一个固定半径值的巷道或钻孔的模型上用一种典型的岩石进行。
