It is firstly found that the NOx concentration increases rapidly when is less than 0.75, which complements the staged combustion and the rich-lean combustion that are well considered currently as low NOx combustion. It does not mean that the combustion must be the low NOx combustion when . There is a limited least value of air excess coefficient. The combustion is not the low NOx combustion when is less than the limited least value.

对目前普遍认为的分级燃烧和浓淡燃烧可以降低NO_X排放的提法给予补充，即对一次过量空气系数有一个最小值限定，不是小于1的任何值都可以，低于最小限定值将是不利的，而且一次过量空气系数有一个最佳值。

Friction coefficient of different tobacco package paper was measured,and the data was analyzed and compared with these different parameters.

通过对不同的烟标纸进行摩擦系数的测试，比较并分析了不同因素对烟标纸摩擦系数的影响。

What is the sampling distribution of a regression coefficient?

分别回答什么是回归系数，什么是回归系数的样本分布？

In order to determine the principal factors and characters, which affect industries evaluation and development, the paper builds character variable of regression coefficient and using the character variable classify industries.

进一步通过建立回归系数特征变量，分析不同行业的回归系数，并确定影响行业发展与评价的主要因素及特征，根据其特征将行业进行分类。

Base on the elastic-plastic contact theories, the calculation model of restitution coefficient both in normal and tangential impacting direction are studied.

本文将以弹塑性接触理论为基础，研究了滚石法向恢复系数、切向恢复系数的计算方法，运用运动学的基本方程研究了滚石在坡面上的运动特征，推导了相关的公式。

Lower coefficient of restitution means higher Shock, Work, Shoulder Pull, Elbow Crunch, and Shoulder Crunch.

拍线张力增加，复原系数会下降。更低的复原系数意味着更强的冲击，功，拉肩，对肘和肩的冲击。

The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking account of friction, is proposed according the Newton first law. And the shortages of former researchers are justified.

刚体碰撞是力学上的一个经典问题，但目前大都采用给定恢复系数进行分析的方法，本文则直接从两刚体碰撞时Newton第二定律出发，建立了计及摩擦的两刚体碰撞基本理论，并指出了以往研究通过给定恢复系数方法的错误之处。

Among 6 influential factors, only the feature of overburden and vegetation play an important role of controlling the restitution coefficient of rolling rock, which can be expressed by a linear relation.

斜坡覆盖层和植被特征对滚石碰撞恢复系数起控制性作用，其他因素几平无影响；斜坡覆盖层与植被特征和碰撞恢复系数之间可用线性关系描述。

Coefficient of restitution????

回弹系数；恢复系数

The numerical results of static friction coefficient showed that it first increases and then decreases with the increase of load.

根据分形转变模型计算的静摩擦系数与载荷的规律是：随着载荷的增加，静摩擦系数先是增加，然后又减小。

What would he tell Judith and the children?

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
