已授权的“平衡电压数字接口电路的电气特性”EIA RS - 422 - A标准定义了RS - 422接口电路的特性。
The EIA Standard RS-422-A entitled "Electrical characteristics of Balanced Voltage Digital interface circuits" defines the characteristics of RS-422 interface circuits.
物质的聚集状态不同，因而定义的标准状态不同，故在标准状态时的化学势各异，标准平衡常数与标准态化学势有关，与经验平衡常数有别。
As substances are in different aggregated states, there are different definitions of standard states, and different chemical potentials in standard states.
