一种是类似于弗朗克-卡敏涅茨基对均匀可燃混气自燃所用的稳态分析理论。

Now the thermal comfort indexes commonly used are ASHRAE Standard 55-1992 and ISO7730, which are both based on young people in Europe and unsteady indoor environment. In fact, it is not quite fit for Chinese people in semitropics and in passive non-air-conditioned buildings, as China has different climate and custom from European and the indoor environment in passive non-air-conditoned building is unsteady, which is different from air-conditioned building, either.

现行通用的ASHRAE55-1992标准和ISO7730标准都是针对欧美国家青年人提出的，并多以稳定的空调室内环境作为分析基础，因此对于我国多样气候环境下的亚洲人群而言，该类标准在适用性上将会存在一些偏差，同时也不能对被动式太阳能建筑室内非稳态环境下的人体舒适性做出十分准确的预测。

In Chapter 2, we study exact solutions of the separated parts of Klein-Gordon field equation on some stationary and axisymmetry black hole backgrounds. We demonstrate that the radial and angular parts of a massive scalar field equation in the Kerr-Newman and Kerr-Sen black hole space-times satisfies the generalized spheroidal wave equation which is, in fact, a confluent Heun equation.

The results obtained from simulation with MATLAB tools and tests, show that dynamic and steady performance and the Robustness of the improved servo-system has been increaded.

利用MATLAB工具进行仿真，结合试验结果表明，改造后的系统鲁棒性较好，稳态性能和动念性能提高。

The experiment results show that the steadystate sideslip characteristics of the tire on the icy road are different from those on the ordinary dry road.

试验结果表明：冰面上轮胎的稳态侧偏特性有不同于干燥路面上的特殊规律。

It is found that if the ratio of the number stored in the model P to the size of the network N is less than 0.1, the following results exist. The overlap between the stable state of networks and the pattern is independent of the size of networks. And the relation between the overlap and the ratio of links of new nodes to the number of patterns abides by the sigmoidal curve.

发现在模型的储存模式的数目P与网络尺度N的比值P/N＜1／10的条件下，网络对受污模式做出响应达到稳态后，这个模式与原模式的重叠随网络平均度变化的规律与网络尺度无关，并且模式重叠与每个新增节点的连接度m和储存模式的数目的比值m／P满足S型曲线。
