查询词典 particles

Using hundreds of computers, Choptuik and Pretorius calculated the gravitational interactions between the colliding particles and found that a black hole does form if the two particles collide with a total energy of about one-third of the Planck energy, slightly lower than the energy predicted by hoop conjecture, as they report in a paper in press at Physical Review Letters .

超普图伊科和佛朗斯使用数百台计算机计算碰撞粒子之间的重力的交互作用，他们发现，一旦碰撞粒子的总能量达到&普朗克能量&的三分之一，黑洞就可以形成，比连环推测预言所需要的能量要稍小一点。他们在《物理评论快报》上发表了这一实验结果。，所以容易被曲解为产生了理想的效果。

含氟牙膏中一般含有氟化钠或单氟磷酸钠，pH值低于7，在摩擦剂的协同作用下是否对口腔中钛制修复体有磨损和腐蚀作用，使其发生失泽和变色，以致影响它的美观和长期使用？

In this thesis, the basic arithmetic of PIV software - cross-correlation arithmetic is introduced in detail, During the data process, through processing the two sequential images by the cross-correlation arithmetic, the vector charts of particles velocity can be obtained, so is the chart of absolute velocity, with velocity decomposed into the radial velocity and axial velocity.

本文对试验所获得的连续图像通过互相关算法，获得颗粒速度矢量图，并将速度分解为径向速度和轴向速度，对每一小区域内的颗粒按速度方向不同进行速度平均，获得颗粒的平均速度分布曲线。

The calculated results show that the enhancement factor increases with the increase of absorbability of particles.

计算结果表明：增强因子随微粒吸附容量的增大显著增加；微粒距离气液界面越远，微粒吸附能力对气液传质的增强越小；在相同粒径与微粒距离气液界面距离的条件下，增强因子随微粒在气液停留时间的增加而增加，但是当停留时间超过一定值后，随着停留时间的增加，增强因子下降；粒径增大，增强因子减小。
