例句与用法

  • If the incident proton collides with a proton bound in a nucleus, the threshold energy is lower because the target proton is bound .
    如果入射质子是与束缚在原子核内的质子相碰撞,那么阈能会低一些,因为作为靶的质子是束缚着的。
  • It was found that the simple triangular shape distribution would cause " two - peaked " energy distribution near the threshold energy , which must affect the group transfer matrix
    阈能处三角形能谱分布的近似描述,导致产生了群散射矩阵的“双峰”现象,而阈能处矩形能谱分布使平均次级中子能量(
  • The relative momentum of two final particles and the cross section are zero at the threshold energy for an endothermic reaction , while the relative momentum of two initial particles is zero and the cross section at the threshold energy for an exothermic reaction is infinite
    在吸热反应的阈能处,出射粒子的相对动量以及截面均为零。在放热反应的阈能处,入射粒子的相对动量为零,截面趋于无穷大。由于强子的动量仅提供如此低的质心系能量,强子物质中x 。
  • We also experimentally observed the effect of sodium atom - molecular collisions and sodium atom - atom collisions on the line - shape and intensity of fluorescence spectra . in addition , the optically pumped infrared stimulated emission and energy transfer up - conversion process are observed in pr3 + : y2sio5 , and with the threshold energy , temperature dependence and divergence angle for the stimulated radiation are measured
    此外还研究了掺杂在固体y _ 2sio _ 5中的pr ~ ( 3 + )的光泵红外受激辐射和能量转移上转换,分别测得了红外受激辐射的阈值能量和发散角,并拟合得出了能量转移速率。
  • Finally , a specific analysis is made for our results . because we have considered the correlation between the confined and non - confined direction of the wire , the binding energy is improved and correspondingly the threshold energy is enhanced , which results in the declinement of the photoionization cross - section
    最后对所得结果进行了详细的讨论,山于我们选取的波函数考虑到限制方向与非限制方向的相关性因素,从而提高了杂质的束缚能(在宽阶时尤为明显x即提高了所谓的阈能( e ,导致了光电离截面值的减小

百科解释

In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide. The threshold energy is always greater than or equal to the rest energy of the desired particle.
