降滴法 的英文怎麼說
中文拼音 [jiàngdīfǎ]
降滴法
英文
falling drop method-
The higher temperature, the more fe ( co ) 5 decomposed in the gaseous phase. when the temperature was raised to 150, the thermolysis entirely happened in gaseous phase and the particles of 2 - 4um formed in long chains. with long chains broken, the plural relative permittivity ( e ", e " ) drop and plural magnetic permeability ( u ", u " ) rise
