查询词典 backward

An elliptic rotating field is produced when an induction motor operates in asymmetry, this paper proposes a model of jointed motion to describe the motion of an elliptic rotating vector and states that the elliptic rotating vector is jointed with two components, the main one rotates forward at a uniform speed while the adjunctive one jointed at the topend of the main one rotates backward around the joint point at a double speed, both make the elliptic rotating vector rotate at swinging amplitude, speed and direction.

感应电机不对称运转时产生椭圆旋转磁场，本文建立了描述椭圆旋转矢量的接合运动模式，说明椭圆旋转矢量是由一个主矢量带动一个付矢量一起旋转构成的接合矢量，主矢量以匀速旋转，付矢量链接在主矢量顶端同时绕着链接点相对主矢量以二倍速反向旋转，两者共同构成的一个单向椭圆旋转矢量。

In this paper,results of Markov chain are used under the circumstances of the automaton model which belongs to logical level of Discrete Event System to analyze the steady states and transient states of the Markov model of DES,respectively based on four conditions of discrete-time parameter and continuous-time parameter.A simpler decision rule of system ergodic property which applies both to the conditions of discrete-time parameter and continuous-time parameter is presented through an example.The transient states of DES which under the condition of continuous-time parameter are analyzed and computed based on Kolmogorov backward equation or forward equation.

利用马尔科夫链的结果，在离散事件系统逻辑层次的自动机模型基础上，对DES的Markov模型的稳态和暂态特性，分别从时间参数连续和离散的情况下，分四个情况进行了分析，通过实例对系统遍历性提出了一条更简单的且在连续和离散时间参数情况下都通用的判定规则，并利用Kolmogorov向后或向前方程，对连续时间参数DES的暂态特性进行了分析和计算。

There was one time when the whole nation has an upsurge of learning computer skills. Our factory also managed to give some lessons. Things like hard drive, RAM, keyboard, none of them I could understand. I didn't really mean to learn. In a small backward city like ours, the factory business is not promising. The salary of my wife and I put together can barely maintain the everyday life. Computer is an extravagancy that was too remote for us. I once believed that's something I could never afford to buy (about 10, 000 RMB for each at that time). Even if I could afford one, I was interested in it.

曾几何时，神州大地掀起了一股学习计算机的热潮，公司也组织过学习班，什么硬盘，内存，键盘我一个词也听不懂，我也没想学，在我们这样落后的小城，工厂也不景气，俩个人的工资只够维持日常生活，计算机是离我们很遥远的东西，我认为这辈子也不可能买的起，就是买的起我也没想过要那玩艺，呵呵。
