Therefore,taking the disjunctive proposition as the prerequisite can attain the new by inferring from the known.

As it is,they have been drilling for sixteen hours and they still have a long way to go.

实际情况是，他们已经钻了16个小时了，并且还要有很长一段时间持续下去。

Different from the case of strict minimal siphons in a net system, the number of elementary ones is bounded by the smaller of place count and transition count. Based on the ideas mentioned above, this thesis proves that the set of elementary siphons is not unique, while different ones may lead to different control results.

本文在此研究的基础上，论证了网系统中的基本信标的不唯一性，控制不同的基本信标可以得到不同的控制效果，进而提出了最优基本信标的概念并给出了相应的计算方法，应用这一计算方法可以在多项式时间内求得一组最优基本信标，也就是说，控制该组基本信标相对于其他的基本信标可以使得系统Petri网模型具有最多的可达状态，这在实际中，意味着系统具有更大的灵活性。

Time series prediction is a very important problem in many applications and the current prediction techniques are nearly all based on the Takens' embedding theorem. Many realistic systems are parameter-varying systems, and the embedding theorems are invalid, predicting the behavior of parameter-varying systems is more difficult.

时间序列预测是一类非常重要的问题，但基本上局限于参数不可变问题的研究，而对实际问题中经常出现的更重要的参数可变系统的预测，由于构成几乎所有已有预测技术基础的Taken嵌入定理不再成立，所以这方面的研究成果极少。

The regulation the author is removed to structuring illegal evidence of our country brings forward a little feasibility's , has the operatability suggestion, believe in by efforts made for a period of time, the regulation illegal evidence of our country is removed is able to establish the form removing the regulation entireness with being put into effect , being reaching illegal actual union our country evidence anticipating really.

笔者对于构建我国非法证据排除规则提出一些可行性的、具有操作性的建议，相信经过一段时间的努力，我国的非法证据排除规则能够真正确立和实施，达到预想的结合我国实际的非法证据排除规则的完整形式。

Most real populations are not at their constant equilibrium density for very long, but are dynamic and changing.

大多数实际种群并不是在平衡密度停留很长时间，而是动态的不断的发生变化。

AND CHAOS Most real populations are not at their constant equilibrium density for very long, but are dynamic and changing.

And then, in the foundation of the overseas scholars'study, I study RP and the CRP methods for visualization the dynamics characteristic of the phase space track as well as the complexity degree algorithm of chaos time series——ApEn algorithm. Applying these two methods based on the VB program we analyze separately the data which is obtained from complex financial system model and Lorenz system, and obtain several new recurrence plots and cross recurrence plots. This provides the graph gist of determination complex intrinsic characteristic. The results establish the foundation for exact and further division of chaos time series.

接下来，在国外学者研究的基础上，基于混沌时序形象化相空间轨迹的动力学特征的分别研究了RP和CRP方法以及判定混沌时间序列的复杂度算法的ApEn算法，基于VB程序应用这两种方法分别对Lorenz系统及实际的一类复杂金融系统模型所得到的数据进行了分析，得到了几个较为新的复原图和相干复原图，这对于判定时序数据的复杂内在特性提供了图形上的比对依据，研究结果为混沌时序的准确和进一步分类奠定了基础。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
