一、低温处理有两类一般的低温处理意味着在0℃以下的处理,也叫深冷处理。这样的冷处理根据零下温度的高低被分为两类即: (1)一般的低温处理:最低至-100℃的处理。 (2)超低温处理;-130℃以下的处理。一般的低温处理通常使用干冰,而超低温处理通常使用液态氮。在学术上进行判断是没有区别的,可是在实践中把-130℃作为分界,分成一般低温处理和超低温处理。超低温处理也可说成致冷处理(Cryogenictreatment)。
First, the low-temperature treatment There are two types of general low-temperature treatment means below 0 ℃ treatment, also called cryogenic treatment. Such cold treatment is divided into two categories according to the level of the sub-zero temperature: (1) General low-temperature treatment: the treatment up to -100 ° C. (2) ultra-low temperature treatment; -130 ℃ the following treatment. Normal low temperature treatment usually uses dry ice, while ultra-low temperature treatment usually uses liquid nitrogen. In the academic judgments there is no difference, but in practice the -130 ℃ as the boundary, divided into general low temperature treatment and cryogenic treatment. Cryogenic treatment can also be referred to as cryogenic treatment.
