幻像信号

Total circuit scheme and time sequence of tool design and implementation have been designed on the AIL logging characteristic. The design and analysis for circuit unit have been carry out on the several units such as main control circuit, signal phantom circuit, signal control circuit, amplifier circuit, A/D circuit, transmitter drive circuit and power circuit.

按照AIL的结构特点，进行了仪器总体设计，设计了仪器工作电路原理和工作时序，在此基础上，进行了主控制电路、信号幻像转换电路、信号控制电路、放大电路、A/D转换电路、发射驱动电路、电源电路等单元电路的分析和设计，从而完成了仪器单元电路的设计与实现。

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。
