负供电轨

Ideal for 3V or 5V single-supply applications, these devices operate from a single +2.5V to +11V supply (or 1.25V to 5.5V dual supplies), and each comparators input voltage ranges from the negative supply rail to within 1.3V of the positive supply.

为3V或5V单电源应用的理想选择，这些器件工作于+2.5 V至+11单电源电压（1.25V至5.5V的或双电源），并在为1.3V从负供电轨每个比较器输入电压范围的正电源。

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。
