Newton's laws, concepts of momentum, energy, angular momentum, rigid body motion, and non-inertial systems.

牛顿定律，动量的概念，能量，角动量，刚体运动，以及非惯性系。

Although the Preissman scheme of KP equation is multisymplectic, it took too efforts to realize, Hence we elimate the auxiliary variable by a trivial computation and obtained the multisymplectic forty-five points scheme of KP equation. And then, we test this forty-five points scheme on soliton and solitary waves over long time intervals, the numerical results shows the propagation and interact of soliton and solitary waves.

但是在实际的数值实验中，由于需要计算共轭动量的值，Preissman格式需要占用的计算内存比较大，计算时间比较长，因此我们在数值格式中消去共轭动量，最后得到与多辛Preissman格式等价的一个多辛45点格式，我们用这个格式进行了数值实验，数值实验结果很好地显示了孤立子和孤立波的传播与碰撞。

According to this equation, one parton will evolute to two smaller x partons continuously, then the parton density at small x becomes very large, and the recombination between partons is inevitable.

根据AP方程，部分子不断地从一个演化为两个较小动量的部分子。

However, the single closed loop controlling only can make the ratio a certain number, the defect is it could not eliminate the spontaneity surge of main momentum, so minor momentum changes when the main momentum fluctuates, the total flux could not remain fixedness.

然而单闭环比值控制系统仅能实现从动量Q2与主动量Q1间的比值为一常量，但这种系统的不足之处是主控量的自发振荡不能消除，从而导致了从动量跟着主动量的波动而变化，使该系统控制后的总流量不是一个定值。

Actually, the amout of maximum stability is also a function of center of gravity travel.

实际上，最大稳定性余量也是重心移动量的函数。

In the specific quantum numbers configuration of holon-isospin excitation where the excited momentum approach to the ground state, the dispersion relations can be expected as a quadratic dispersion, so we can define the effective mass of the spin wave excitation.

在激发能动量接近基态的特殊的isospin 量子数选取下，可以把色散关系看成为二次函数的形式，由此得到了有效质量与能隙、激发态动量的关系。

He needs a neat diet and plenty of hard exercise to toughen him up.

他需肉类饮食和大运动量的艰苦锻炼使自己强健起来。

In order to overcome the difficulty in estimating the ripple component on dc-side capacitor reference voltage, the modified control algorithm is proposed by ignoring the ripple component. Furthermore, the relation between control performance and damping coefficient is researched. In addition, the reasons of voltage source converter inner-loop control overmodulation are also analyzed. Based on the relation between control performance and VSC inner-loop input saturation, damping coefficient is adjusted on-line by fuzzy logic reasoning so that the trade-off between control accuracy and limitation of VSC inner-loop control overmodulation is solved preferably.

由于在线计算直流电容指令电压波动量十分困难，在控制方法的执行中忽略波动量的影响，简化了控制方法的实现；此外，该方法还研究了所注入的阻尼大小对控制效果的影响以及APF内层控制过调制产生的原因，针对无源性控制律跟踪精度的要求与内层控制过调制限幅条件间的矛盾，通过构造模糊逻辑推理环节实现阻尼系数的在线调整，在满足内层控制限幅条件下确保跟踪精度和补偿效果。

It suggests that the horizontal momentum of the meso-cyclone was brought down to the surface by heavy rain. At the right edge of meso-cyclone the momentum and RIF have the same direction, the two airflows overlay together and make the wind increase, so damage wind occurred.

分析认为，弓状回波后部存在较强后部下沉入流，由于强降水的拖曳作用，将中层中气旋的水平动量带到地面，中气旋右侧动量的方向与弓状回波后部的强下沉入流方向一致，两者叠加，使地面风速加大，造成灾害性大风。

Firstly,accordingto information entropy uncertainty relation of position and momentum,the definitionon squeezing in information entropy of position and momentum of the field is given.

首先，根据位置与动量的信息熵测不准关系，给出光场位置与动量的信息熵压缩定义。
