At first, with the low-frequency data measured, three of the LRE fault detection systems for the real-time condition are proposed using the nonlinear identification technology of the BP neural network, the state estimation technology of the dynamic neural network, and the pattern recognition technology of the fuzzy hypersphere neural network. The learning algorithms of the BP and dynamic neural network are researched at the same time. Furthermore, while the engine operation is divided into the start and steady-state processes, the real time ability, the response time, the accuracy, the robustness, the sensitivity and the monitoring parameter optimization are studied. In the test data analyses of the YF-75 engine, the detection system correctly carried out for all normal tests, and in the three abnormal tests the engine faults were accurately forecasted.

As to the dynamic loads, the calculation considers only the inertial loads because of jump-start and brake. However, in the actual turn-over processor of the circumgyrate machinery, especially in the process of braking, the impact to the organization is very obvious. Now in the strength calculation of the circumgyrate machinerys parts, this distinct dynamic effect is replaced by safty coefficient.

然而，在回转机构实际的运转过程中，特别是在制动时，机构中发生的冲击振动现象十分明显，但这种非常显著的动态效应在回转机构的强度计算中仅由安全系数来考虑，也就是把较复杂的动态系统人为地转化为简单的静态系统并没有准确地反映事物的本质。

Urban forest is the lively infrastructure of a city. As citifying process develops, it is impossible to develop large-scale green land in the downtown of a city. What s more, the efficient city ecological green-land system, which doesn't equal to the simple that expansion, requires considerable proportion of suburb green space and city forest resources, in order to deeply control the space-time development of those resources and accurately understand the various influence that natural and unnatural factors bring to those resources.

城市森林是有生命的城市基础设施，随着城市化进程的推进，城市中心区不可能大规模地发展绿地，而且，高效的城市生态绿地系统不是简单的成片扩展，要求含有相当比例的近郊绿色空间和市域林带，因此，为了更好地掌握城市森林资源的时空动态，准确了解自然因素和非自然因素对城市森林资源产生的各种影响，就必须对城市森林资源实施动态监测。
