退磁装置

Using simple device, the demonstration experiments of demagnetization and self induction are redesigned.

利用简易装置对高中教材中的退磁和自感演示实验进行了再设计，介绍了演示方法，并对实验现象给出了解

MFL signal process systems and online demagnetizable equipments used in foreign testing equipment are developed on the basis of these researches and applied widely.

在上述研究的基础上，研制出适用于国外设备的漏磁信号处理系统及钢管在线退磁装置，取得良好的应用效果。

Secondly, basing on the analysis and research to the original measurement system NIM-10000H, the methods of exerting demagnetizing electric current and measuring flux are found out and the device is designed. Experiments are made to prove the feasibility of the device. Although there is feasibility in theory, it should be further research and perfection on making sure the exact electrical current.

第二部分是在对原有检测系统NIM-10000H进行分析和研究的基础上，逐步摸索出施加退磁电流的方法和实测磁通的快速检测方法，并设计出实验用的装置，加以实验验证是否可行，是否能达到快速检测，最终给出初步的结论，该方法可行，只是速度还不够快，而且电流大小的确定还有待进一步的研究和完善。

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。
