轴效应 meaning in English

shaft phenomenon

When the spatial parameter a is small , the non - paraxial effect does n ' t affect the temporal profile of the beam . however , when a becomes relatively larger , it influences the temporal profile greatly
当空间参数较小时超短脉冲贝塞尔光束的时间波形不受非近轴效应影响；然而当空间参数较大时，非近轴效应影响超短脉冲贝塞尔光束的时间波形。
However , the effect of rsf leads to the singularity of beam redius focused to zero with infinity laser intensity when the laser power is lager than a critical value in the absence of other effects . then , we anlyze the effect of higher order relativistic nonlinearity ( hor ) and find that this effect can arrest the singularity due to the effect of rsf
因此，研究了高阶相对论性非线性效应对激光传输的影响，发现高阶相对论性非线性效应能够抑制这种奇异性的出现；并对高阶相对论性非线性效应与非傍轴效应作了比较，发现高阶相对论性非线性效应起主要作用。
