近似值

In the paper, the stability of the static states of the system was discussed theoretically and the control parameter was determined nearby the point of Neimark-Sacker bifurcation.

首先利用理论分析了一个二维离散超混沌系统的不动点的稳定性，以此得到系统发生Neimark-Sacker分岔时参数α的近似值。

In Chapter 4, there are two important structures, loops and stacks for an abstract single-strand RNA. Based on the method of combinatorial enumeration, we make a new discussion about the enumeration problem and get its approximation with the limited length of end loop.

第三部分：RNA二级结构是由一些环和茎组成的结构，在此基础上，本节以端环中自由基数为参量，我们又利用组合技巧解决了一类RNA二级结构的计数并给出了它们的近似值。

The trick about floating point numbers is that although they are extremely useful for representing real-life quantities, operations on them do not obey the arithmetic rules we learned in middle school: associativity, transitivity, commutativity; moreover, many very ordinary-seeming numbers can be represented only approximately with floating point numbers.

For example：有关浮点数的诀窍是，尽管他们是用来代表我们生活中的数，但操作却不符合我们从中学学到的运算法则：结合律，交换律等等，另外许多时候浮点数只是近似值。

This approach was to replace the derivative operator in the continuous time model by an approximation and estimation of the physical parameters of structures by the least-squares method.

讨论了导数近似值的选择方法，并分析了算法的收敛性。

Thus, there is no way to demonstrate that sufficient data has been collected to form a mathematically valid approximation (or known degree of approximation) of the complete data set.

因此， 没有方法示范充份的数据已经被收集形成完全数据组的一个算术有效近似值。

But for the middle and large scale problems, the computation cost by symbolic differentiation is very expensive. When the direction derivative is evaluated, the computation cost by divided difference can be reduced, but it is only one kind of approximate computation.

对于大中规模问题来说，使用符号微分，成本昂贵，有时甚至不可行，在计算导数的方向梯度时，利用差分法虽然可以降低计算成本，但得到的是近似值，而且确定恰当的差分区间也很困难。

By agreement, a practical approximation of the elastic limit, called the offset yield strength, is used.

因此我们定义了一个实际存在的，弹性极限的近似值，称为残余变形屈服强度。

Elastic Limit, Apparent—Arbitrary approximation of the elastic limit of materials that do

表观弹性极限—应力-应变曲线中没有明显线性段的材料的弹性极限的近似值，它等

Highly accurate approximations of the elliptic function are obtained in this paper through the use of Gauss transformation, which could not be obtained by the traditiona...

运用高斯变换法求椭圆函数的高精度近似值，解决了过去沿用椭圆积分表达不到精度要求的困难。

It is noteworthy that, the suburbs of the annual supply of the first approximation of the amount of urban development at the same time last year in the property market have emerged in several leading real estate to make the representation of talent.

值得注意的是，郊区的年度供应的第一近似值的数额城市发展的同时，去年房地产市场中出现了几个主要的房地产，使代表的人才。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
