次极限

Most of them rely on the central limit theorem, that states that the mean of N independent realizations of a random variable with mean u and variance d^2 approaches a normal distribution with mean u and variance d^2/N .

在蒙特卡罗评估框架内大量的各种选择性算法已经被推出，他们中的大部分依赖于中心极限定理，一个均值为U方差为D^2的随机变量的N次独立实现的平均值接近于一个均值为U方差为D^2/N的正态分布。

Uncertain general MDP with compact parameter set is discussed, and a sub-optimal adaptive control method is proposed.

分析和证明了一般MDP的极限分布和目标函数的连续性，并在此基础上将参数集离散化方法推广到一般MDP，获得了能够以任意给定精度实现次优的自适应决策方法。

O1 c compactness of the entropy equation; At last, coupling with Kinetic formulation, we can obtain the existence of a strong convergent sequence, then the limit function is just the entropy weak solution of the original systems.3. Existence of global entropy solutions to an inhomogeneous elastodynamics system.

o1 c紧性，最后结合Kinetic理论得到粘性解存在强收敛的子列，从而可得该极限函数即为原方程组的熵弱解。3、研究了一类非齐次弹性力学方程组整体熵解的存在性。

In truth, many governments may find it impossible to do this again, since they may reach the limits of creditworthiness.

事实上，许多国家的政府可能发现根本不可能"再来一次"，因为他们可能触及信用额度的极限。

In this paper we discuss the limit cycle problem for a non-Liénard type cubic system.

本文讨论了一类非Liénard型三次系统的极限环问题。

Bifurcations of limit cycles of a cubic Kolmogorov s system are investigated at the positive equilibrium point .

研究了一类三次Kolmogorov系统在正平衡点处的极限环分支问题。

Chapter 4 investigates the number and distributions of limit cycles for a class of Kukles system, which also can be regarded as a class of reduced Kukles system under cubic perturbation.

第四章研究了一类Kukles系统的极限环的个数与分布，这里我们把所研究系统看作是三次扰动下的退化的Kukles系统。

A closed calculation form of the curvature is given based on the theory of matrix.(7)A case study of high slope reinforcement is presented. The whole process of the uplift test and the computer simulation of cable are expatiated. The excavation of the slope with or without reinforcement is simulated by numerical method.

利用矩阵理论给出了求解曲率的简化算式，提出了一种相关变量可靠度计算的实用二次二阶矩法；(7)借助某高边坡支护工程，详述了锚索极限抗拔试验和数值模拟。

It only has a few hundred cycles -- from charged to empty -- before it starts to resemble a very expensive doorstop.

电池一般只能反复充电几百次，过了这个极限它就会像旧门簧一样无法工作了。

Since these merits, Dyn's four-point scheme is one of the classical subdivision schemes in CAGD.

本文讨论的是前者。1987年，Dyn提出了四点细分算法，它形式简单，最高具有四次收敛阶，并可以生成一阶连续的极限曲线，由于这些明显的优点，四点法成为CAGD中经典的细分算法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
