After disinfection and medical activities before, samples were taken from three points in a diagonal of a relatively closed space with area not more than 30 square meters. In general, one point was from diagonal center, and the other two points from the two ends with one meter distance to walls. When the area exceeded 30 square meters, samples were collected from five points, one was from the center, and the other four points from four angles with one meter distance to walls, and the altitude was 80-150 cm from vertical distance to the ground. The total number of microbes not more than 200cfu/m^3 was considered qualified.

消毒后和进行医疗活动之前，相对封闭的空间，面积≤30平方公尺时，在一条对角线上取3点采样，一般是中心和两端距墙壁1米处各取1点；面积＞30平方公尺时，应取中央及四角距墙壁1米处共5点采样，布放高度为垂直地面80cm~150cm，微生物总数≤200cfu/立方公尺为合格。

该方法首先预形成指向4个方向的宽带无失真波束，各自的主瓣区域把整个空间分为4个不同的测量区，然后分别将这4个波束形成器的波束输出作为参考点接收到的声信号，利用基于时延的定向方法定向处于不同测量区的声源。

The measurement equation of four point method and three point method flat form error separation is given.

列出了四点法－三点法平面误差分离的测量方程，导出了这类方法所对应系统的传递函数G的通式，指出G（0，0）＝0是平面形状误差赖以先行分离的先决条件。

In this dissertation, we have arranged the contents as"from overall to partition, and then from partition to overall". First, we systematically study four parts: detection information fusion, state information fusion, attribute information fusion and decision information fusion, then from higher point of view we integrate the four parts. Furthermore, on the basis of the theoretical studies, some effective approaches to the engineering practical problems, which are difficultly solved by the traditional approaches, are provided.

本文针对此问题按着"从整体到局部，由局部再到整体"的研究思想，首先系统地从检测信息融合、状态信息融合、特征信息融合和决策信息融合四个方面进行了研究，然后从更高的角度将上述四个部分进行融合，并为解决某些传统理论难以克服的工程问题提供了新的有效方法。
