查询词典 small particles

A new particle swarm optimization, PSO with bounded mutation operator, was developed. In contrast to the original PSO, in this algorithm, PSO with bounded mutation operator would make the particles redistributed cquably close to boundary when place of particle exceeds feasible region during iteration.

提出了一种新的粒子群优化算法——带边界变异的PSO，其原理是：在迭代的过程中，当粒子的位置超出可行域时，带边界变异的PSO让粒子的位置重新均匀分布在边界附近；当粒子的速度超出可行域时，则使其均匀分布到整个可行区间，而不是像原始PS0那样在这2种情况下都只是简单地取边界值。

You'll also notice a bounding box around the particles to indicate that the point cloud is selected.

同时有一个边界盒子围绕在粒子群周围标志着粒子当前为选择状态。

A white bounding box around the particles indicates that the point cloud is selected.

环绕粒子的一个白色的方块显示点云为选择状态。

Characterization of complementary DNAs derived from braconid wasp ovaries identified genes encoding subunits of a viral RNA polymerase and structural components of polydnavirus particles related most closely to those of nudiviruses—a sister group of baculoviruses.

基因编码的RNA聚合酶亚组和多去氧核糖核酸病毒粒子的结构组件，与nudiviruses有着密切的联系。而通过来自小茧蜂卵巢互补DNAs的表征可以将两者识别出来。

Rules for fusing, which specify the possible values of the charge that can be obtained when two particles of known charge are combinedbtogether, used for reading out information. In the #nu=5/2# FQH state, it can be realized by measuring whether each pair annihilates fully or not with interference experiment. The representation of the braid group realized by n anyons is cmpletely characterized by the R-matrix and F-matrix which satisfy a pentagon equation and a hexagon equation, coherence conditions for the corresponding anyon model.

满足一定的聚合规则，用于信息读取（在填充因子为5/2的分数量子霍尔效应中，可以通过干涉实验测量每对相邻的粒子相聚合的湮灭情况来实现信息读取）；N个任意子组成的体系的标准基中辫子群表示可以完全由R矩阵和F矩阵决定，不同任意子模型中的R矩阵和F矩阵的具体形式可以通过五边形和六边形方程求出。

The relations of the ratio of density to the ratio of vertical height of the two kinds of particles are calculated, which shows that the main factor of granular oscillation is not the "Brazil nut effect" or "reverse Brazile nut effect".

通过计算在垂直方向上两种颗粒高度之比随颗粒密度的变化关系，说明决定颗粒振荡与否的主要因素并不是"巴西坚果效应"或"反巴西坚果效应"。

织绒面呢只不过是按独特方式重新排列羊毛的粒子

12 According to De Broglie, light possesses wave-particle duality like any material particles.

根据De Brogile，光象其它的物质一样具有物质微粒的二元性

According to De Broglie, light possesses wave-particle duality like any material particles.

依据德布罗意的理论，光和一切物质粒子一样具有波粒二重性。

Between 1930 and 1950, Louis de Broglie's work has been chiefly devoted to the study of the various extensions of wave mechanics: Dirac's electron theory, the new theory of light, the general theory of spin particles, applications of wave mechanics to nuclear physics, etc.

第一次世界大战期间，德布罗意在军队服役，被分配到无线电台工作，中断了他的理论物理研究。1919年，德布罗意重新回到他哥哥的实验室研究 X 射线，在这里，他不仅获得了许多原子结构的知识，而且接触到 X 射线时而象波、时而象粒子的奇特性质。
