求值

N algorithm for close approach determination was developed by Alfano and Negron （1993） based on polynomial splining techniques.

lfano—Negron（1993）提出的空间目标接近分析算法将最小相对距离及其对应时刻和进出误差椭球时刻的求解问题均转化为插值多项式求根问题。A—N算法在判断三次多项式根的存在性、筛选合理实根时存在缺陷，可能导致多余计算。

The establishment of this equation will expand the range of application of evaluating using one-point method.

因此，本方程的建立，扩大了用一点法求算聚合物特性粘数方法中K＇值的范围。

By using Hamilton graph ,the problem of wagons placing-in and taking-out on branch-shaped sidings can be turned into searching Hamilton loop of minimum power.

运用图论中的哈密尔顿图，可以将树枝型专用线取送车问题，转化为求哈密尔顿图中权值最小的哈密尔顿回路问题。

The design shoehorned the designers into that kind of monster design. So we focused on a health system that actually forces the player to think tactically to recover health from monsters and to put them in some situations where they are low on health but have to walk into an enemy encounter anyway.

所以我们把注意力放在了改进生命回复系统上，这个系统可以让玩家从战术层面上思考如何打倒怪物来补充生命，同时在生命值较低的情况下不得不冲入敌阵来求一线生机。

Of all possible perimeters of this type of figures.

求这种图形的周界的所有可能值之和。

The inverse problem is solved using conjugate gradient method of minimization based on discrete ordinates method of radiative transfer equation.

该方法是在辐射传递方程离散坐标近似的基础上，用求目标函数极小值的共轭梯度法进行反演计算。

The widely used method are trial solution and the least square method. They need huge calculations and their results are less reliable. A new kind of intelligent genetic algorithm was employed to get the optimal parameter. Using it in the（ model has proved its reliability for production forecast of oilfield.

各种油气田产量预报模型的应用关键在于参数估计，常规参数估计方法为试凑法和最小二乘法，工作量大，可靠性差，所以引入了一种新型遗传算法求取参数最优估计值，并通过遗传算法在Γ模型中的应用实例说明了该方法在油气产量预报中的可行性。

The initial tension in the rod is found out by iteration,so that the prestress of the rod reaches the design value.

通过简单的回代方法求出每根吊杆的初始张拉力，从而使得最终吊杆的预张拉力达到规定的设计值。

In order to adapt to different production speed, you can use a speed control potentiometer on high speed; adjust the speed of the actual value of the gauge by speed.

为了分适不对别的出不销速率给求，可堵住一个调速电位器不对矮速举行调度，速率的本质值可以堵住速率表辅导出来。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.
