参考点

A point considered to be at nominal zero potential and to which all other potentials in the circuit are referred, often, but not always, connect ed to the actual surface of the earth; as a verb to connect to a ground.

电路中的一个参考点，该点电位作为标称的零电位，其它所有电位均相对于该点而定。经常，但并非总是，将该点直接连接到地。

And selecting one point as reference point, vibration test is carried out in the selected point with stretching group by group.

基于以上两点，本文利用有效独立法对一4米长简支钢梁进行了测点优化和选择，并且选择一测点为参考点，用分批测量的方法对所选测点进行了振动测试。

A new method of automatic segmentation is developed based on the extreme point properties of wavelet transform. The method consists of two main steps: 1. Using the multi-resolution properties of wavelet transform, we can get the information of shape variation with space coordination.

该方法包括两个主要步骤，一是利用小波变换的多分辨率特性得到测井曲线的形态特性随空间坐标的变化信息；二是利用小波变换过零点的特征在不同尺度上的反映，提取不同尺度下的奇异点作为分层的待参考点，结合实际情况最终确定分层点。

As we try to keep up with these varying references, inhibitions build upon themselves and multiply.

当我们尝试要跟上这些变异的参考点时，这些禁忌就互相堆叠而加倍产生。

For example, street signs at intersections are excellent reference points.

举例来说，街交叉口的迹象，在良好的参考点。

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。
