Its test point is used to connect Hot Line Voltage Indicator.

它的测试点,是用来连接热门线路电压指标.

A novel approach to analyze the content of boron trioxide in zinc borate was established using bromocresol green-methyl red mixture as indicator to determine the titration starting point.

建立了一种测定硼酸锌中三氧化二硼（B2O3）含量的新方法，即以溴甲酚绿甲基红混合指示剂来确定硼酸的滴定起点。

By the selection, of the φ value of end-point, modifying the method of end-point detection, or using a correction for indicator error, the titration error can be decreased, so that a more accurate result can be obtained at a less sharp end-point.

对终点φ值进行选择，改进确定终点的手段和对终点误差进行校正，可以降低滴定误差，从而在终点不敏锐的情况下得到较准确的滴定结果。
