Because of the non-linearity, time- variability, multi-parameter, intense coupling of the heating process and especially, the random interfere and anfractuosity of process, precision mathematics model is difficult to be established. The routine PID algorithm can not meet the requirement of control.

With method of radial tracing, path numbe ofmultipath and angle of incidence, times of reflection, attenuation, and delay werededuced based on the theory of stochastic.

根据随机过程的基本理论，采用射线追踪法，从电波散射和绕射原理，推导出高速移动台无线通信多径传播的径数、入射角、散射次数和衰减系数、多径传播路程和时延等的概率分布。

Through simulating the speckle intensity distribution in the far field of a random rough surface,we compute the degree of angular speckle correlation by substituting spatial average in speckle pattern for conventional ensemble average,and determinate the surface roughn.

通过模拟计算随机粗糙表面的远场散斑场，以散斑图面上的空间平均代替常规的集平均来计算角度散斑相关系数，并应用集平均的数学模型反演粗糙度参量。

objective to investigate the clinical therapeutic effect of mucosolvan nebulization in infants with pneumonia.methods 96 infants were randomly divided into and control group.regular treatment were given to control group,meanwhile,based on regular treatment,the infants in observation group were also received mushutan nebulization.the disappearing time of cough、wheezy phlegm、anhelation、wheezy sound in lung and admission duration were evatated.results the disappearing time of wheezy phlegm、wheezy sound in lung and admission duration in observation group were shorten than in control group(p.05).conclusion mucosolvan nebulization can raise clinical therapeutic effect for pneumonia in infants with pneumonia.especially in eliminating phlegm and disappearing of wheezy sound in lung.

摘要］ 目的：为探讨沐舒坦雾化吸入辅助治疗婴幼儿肺炎的效果。方法：将96例婴幼儿肺炎随机分成两组，两组均在常规抗感染，纠正缺氧、酸碱平衡、电解质紊乱，治疗组加用沐舒坦雾化吸入，对照组用α糜蛋白酶、地塞米松雾化吸入。对两组的咳嗽、痰鸣、气促、肺部湿音的消失时间及住院时间进行比较。结果：使用沐舒坦雾化吸入的治疗组在治疗痰鸣、肺部湿音消失时间及住院时间比对照组短（p.05）。结论：沐舒坦雾化吸入可提高婴幼儿肺炎治疗效果，尤其祛痰和减少肺部湿性音的效果较好。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
