初始分布 meaning in Chinese
initial distribution
Examples
- Beam halo - chaos for five different initial ion distributions is effectively controlled by a logarithm - function controller based on the variable
结果显示，新的控制方法对强流加速器中5种初始分布的离子束均有较好的控制效果。 - An explicit solution for the probability distribution as a function of the time and position in the master equation is obtained when the substeps between arbitrary adjacent states in a single period are equal for the molecular motor
并取得了如下成果： 1计算了分子马达在等间距跃迁情况下，当给定初始分布时，任意位置任意时刻主方程中几率分布的解析表达式。 - A simple model for primary breakup of energetic liquid jets was established using unstable wave theory . based on the jet - embedding method , the jet - core shape , the distribution of jet velocity and the primary distribution of liquid drops were computed
使用不稳定波理论，建立了射流初始破碎的简化模型，采用射流嵌入法( je )进行了数值计算，得到了hy911射流核形状、速度分布以及液滴尺寸的初始分布。 - The integrands in the dispersion equation are not integrable in general , so we used the asymptotic expansion solution to analyze the behavior of the dispersion relation at the singularity and mapped the dispersion relation curves approximately the system composed of collisionless particles which obey maxwellian distribution or all kinds of degenerate distribution , even in their mixture system , their dispersion relation are analogous
一般来说，色散方程中的被积函数都是难以求积的，本文是用函数逼近法分析色散方程在奇点处的行为，并大致划出色散关系曲线。由无碰撞粒子组成的系统，不管初始分布是maxwell分布还是各种简并分布，甚至是这些分布的混合体，色散关系都是相似的。 - On the basis of this , we selected rms as feedback variable and constructed the controller g : add this controller to the right of ion radial self - edlctric force equation like equation ( 1 ) . we simulated the motion of ion beam by using muti - paticle code ( partice - in - cell ( pic ) code ) . the results demonstrated that the beam halo of five different initial distribution is eliminated well under the same controller . the halo intensity of k - v distribution , water - bag distribution and parabolic distribution and be reduced to zero . in the case of 3 - sigma distribution and full gauss distribution , the result is agree with minimum limitation ( 10 " ) of halo intensity of factual high intensity accelerator
在此基础上，选择a为控制变量，构造延迟反馈控制器g ： g （ s glrrms （ s ）一rms （ s ） （ 2 ）同（ l ）式一致，将此控制器函数加在粒子径向所受束自生场力方程的右边。利用多粒子数值模拟程序（ pic ）进行了控制试验。模拟结果表明，用同一个控制器和同一个控制参数即可实现五种不同初始分布情况下的束运一混饨的有效控制。
