Those spectra nearer the periphery of the objective are dimmer than those to the central spot 靠近边缘的光谱状亮点的亮度要小于靠近中心的亮点。
The light from an elliptical galaxy is brightest in the center and gradually becomes fainter toward its outer regions 从椭圆星系发出的光在中心部分最亮越靠近边缘越暗淡。
When the fill factor is less than 1 , the concentrated tensile stress appeares near edge of disk surface , while the fill factor reaches up to 1 , the surface exhibites compressive stress , and the center is less tensile stress 当抽运光斑未充满激光介质时,介质的表面靠近边缘处会出现大的拉应力集中,并且介质表面的最大轴向位移和最大拉应力随光斑填充因子增大而增大;而当抽运光充满介质时,表面是压应力,较小的拉应力存在于介质内部。
When the pumping area cannot approach the disk had aperture , the concentrated tensile stress appears near the edge of disk hard aperture , while the disk is pumped full aperture the surface exhibits compressive stress , and center is tensile stress which is lesser 当抽运光斑未充满激光介质时,介质的表面靠近边缘处会出现大的拉应力集中,并且介质中最大拉应力和表面的最大轴向位移随抽运光斑尺寸缩小面增大;而当抽运光充满介质时,表面是压应力,较小的拉应力存在于介质内部。
Particle ratios embody the chemical equilibrium driven by inelastic interaction during rapid expansion when the temperature decreases in the colliding system , the measured hadron ratios provide the chemical composition of the fireball at the chemical freeze - out point and access the baryon transporter stopping ) for the initial conditions at early stage of the collisions . in this paper , we study the anti - proton to proton ratio from ig7au + 197 au collisions , analyzing p / p ratio as functions of rapidity , transverse momentum and centrality at ^ / saw = 200gev and the dependence on the center of mass energy of p / p ratio , compared with the experimental results . it shows that the p / p ratio has n ' t obvious dependence on rapidity for mid - rapidity , but shows a slight increase trend with pt increasing in the range of pt < 1gev / c for mini - bias or central collisions , and rqmd shows a more remarkable correlation between p / p ratio and centrality than experiments do at snn = 200gev 研究表明:对厂在中心快度区没有明显的快度依赖性,在越靠近边缘快度区, p p呈下降趋势;在对心碰撞或者最小无偏事件中, p p在低横动量区域随着横动量的升高而增大; p随着碰撞对心度的比实验结果表现出稍强的随对心度增大而减小的趋势,尤其是有再散射ujrqmd模型;在中心快度区, p p随着碰撞的质心能量的提高而快速的增大,与实验结果一致;在低能,有末态粒子再散射的d较好的预言了的:但是在mc能量下,有末态粒子在散射的d所预言的p p值比实验值要小。
