模拟-数字转换装置

A set of small static electric dehydrator with a computer is established. The current of the dehydrator is monitored in real time through an A/D card installed in computer.

本文在室内建立了一套小型静态模拟电脱水器试验装置，并且通过在计算机上安装A/D转换卡，从而实现了对电脱水器脱水电流的实时监测。

ICL(7106)3_(1/2) bit A/D convertor through the encoder convert the sectional code into BCD code. The BCD output is interfaced with the microcomputer system,when through se- veral aualog channel qnantity is collected we can use the multiplexor. Our experiment has proved that the system has simple circuit with reliabe operation and it is cheap.

本文介绍了 ICL(7107)3_(1/2)位 A/D 转换器段码输出与微机系统的接口电路，ICL(7106)3_(1/2)位 A/D 转换器经编码器，将段码转换为 BCD 码输出与微机系统收接，当对多个模拟量进行检测时可应用多路开关，实验证明联接线路简单，运行可靠，装置便宜。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
