Many results have been gain about the equation's oscillation, asymptotic behavior and stability, etc.

此外，在讨论方程的振动性的时候，我们分三种情形得到了方程振动的充分性判据。

We show that our estimator achieves the same asymptotic efficiency as Lin and Carroll's estimator, but performs better in finite samples.

估计量达到了与Lin和Carroll的估计量相同的渐近有效性，且在有限样本情形下表现更好。

The result obtained shows that the asymptotic formula of finite-time ruin probability which holds in the case that the claimsize is independent, identically distributed i.i.d.

所得结果显示，在独立同分布索赔额情形，有限时间破产概率的有关渐近等价公式，在负相依场合依然成立。

Both single and double-stable limit cycle flutter states are found in wind-tunnel test. And the conclusion is proofed that the equivalent linearization based on the second order asymptotic solution of KBM method is more accurate than that based on the first order one, which is equivalent to the conventional harmonic balance method.

风洞实验时，吹出了单、双稳定极限环颤振情形，并验证了基于KBM二次渐近解的当量线化分析比KBM法一次渐近解的当量线化分析要精确一些的结论。

By calculating the LST and asymptotic series of the service-time distribution we analyze the steady-state waiting-time probabilities of M/G/1 queue system. We also extend the special caseγ=3/2 to the normal case. The results show that it will be helpful to analyze the heavy-tailed waiting-time distribution of self-similar traffic sources. This chapter also proposes a generalized packets loss method.

本章第一部分通过引入一类混合指数分布并证明此类分布服从Pareto重尾分布，得到相应的LST变换闭合形式及服务时间渐进级数，同时将形状参数γ=3/2时的服务时间及其LST变换推广到更一般的情形，较为有效地解决了重尾分布的信源排队等待时间分析问题。

With the help of comparison theorem, sufficient conditions which guarantee permanence of the system are obtained. For the almost periodic case, by constructing a suitable Liapunov function, we obtained that the system has a unique globally asymptotically stable positive almost periodic solution. Finally, we study a multispecies predator-prey system with stage structure and Holling II type functional response.

第二部分考虑具有阶段结构的非自治扩散捕食系统，利用比较定理得到该系统持久生存的充分条件，其后在概周期情形下通过构造合适的Liapunov函数得到了保证该系统存在唯一一个全局渐近稳定的概周期解的条件。

This is the most serious problem at present.

这是目前的最严重的情形。

The number of transplant plugs which should be placed at one session and the frequency of transplant sessions depend on the characteristics of each individual case; they can be planned out in advance for each patient.

移植会议应该在一会议和频率被放置的移植塞子的数字仰赖每个个别的情形的特性；他们为每位病人能预先被想出。

He says he can't imagine another atomic bomb ever being used again.

他说他无法想象又一颗原子弹爆炸的情形。

It was found that in all situations studied here the effect of depletion is attractive when the two colloid spheres close to each other, the attraction depresses the repulsion of charged colloid spheres and gives a net attraction to hard sphere s.

发现在所有情况下，耗尽作用在胶体球靠近时都是吸引的，这种吸引作用减小带电胶球的排斥作用，而在硬球情形下产生吸引作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
