1·This paper introduces the automatic range conversion circuit of voltage, current and resistance normalized measure and the working process of software.

介绍将电压、电流、电阻归一化测量的自动量程转换电路及主要软件流程。

2·The results show that the presence of La, Ce and Nd improves the water resistance of glasses and decreases the normalized releases of silicon.

结果表明：镧、铈和钕等轻稀土的掺杂提高了该玻璃的耐水性，降低了硅的浸出量。
