After getting these four line-of-sight vectors, we inverse these data in special observation coordinate based on space analytical geometry, then we can get the vector that has three components on every coordinate, this vector will be treated as the total wind profile in the three-dimensional observation field, the result of this four-point method can basically reflect all the spatial and temporal variation of the atmospheric wind.

在得到视线方向风速矢量后，从选定的三维观测坐标系对这四个矢量进行空间解析几何的运算，可得到观测坐标系的各坐标轴上四个测量矢量的各坐标分量的标量和。从而以这个在三个坐标轴上都有分量的矢量作为在观测视场内的总的风场的风速矢量。

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。
