freezing medium 中文意思是什麼
freezing medium
解釋
製冷劑-
Isolation : when the measured medium is the matter that is easy to freeze, pour the isolation liquid such as glycerine, antifreezer into the connecting tube to insolate the measured medium and pressure gauge from freezing. at this time, the pressure gauge damp, isolation connecting pipe tube as an isolation vat, but it has low price and excellent function
2隔離：被測介質為易凍易凝物質時，在接管內注入隔離液如甘油防凍液等可起到將被測介質與壓力表相隔離並防止凍凝的作用此時，壓力表減震隔離接管相當於一個隔離缸，但其價格之低功能之優是隔離缸無法比擬的。 -
Method : 120 rabbit vessels were randomly divided into three groups : the vessel of control group in cryopreservative medium containing calf serum were subjeted to rate - controled slow freezing ; those of experiment group i in cryopreservative medium containing mixed animo acids were frozen by the same method as in control group ; and those of experiment group ii in the same cryopreserative medium as in control group were subjected to rapid freezing
材料和方法：取中國純種家兔股動脈120段，隨機分為3組：對照組用含胎牛血清的保護液處理，以慢凍方式降溫；實驗組1用含復方氨基酸的保護液處理，以慢凍方式降溫；實驗組ii用含胎牛血清的保護液處理，用速凍方式降溫。 -
Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control
與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。 -
If the measured medium is water, it can be directly used in normal temperature. in the environment of below zero, we should choose glycerine, alcohol etc. antifreezing medium as isolation liquid to stop from freezing the force meter
如被測介質為水時，在常溫環境中可直接使用在0以下的環境中測應選擇甘油乙二醇類防凍介質隔離液，以免凍壞壓力表 -
This company endeavors to hardening, normalizing, tempering, high and medium temperature quenching, mesh belt furnace quenching, cementing, time effective freezing and high temperature treatment etc
本公司是一家致力於從事調質、正火、回火、高中溫淬火、網帶爐淬火、滲碳、時效冰冷及其高溫熱處理的廠家。 -
Effect of preculture beads were encapsulated and incubated in culture medium containing 2 % peg and 5 % pvp respectively for 90 min before dehydration. cell viability of pavlova viridis was increased by 6 % after freezing. preculture had less effect on cell viabilities of other two algae
（ 4 ）預培養的影響將膠球在分別含有2 %聚乙二醇（ peg ）和5 %聚乙烯吡咯烷酮（ pvp ）的培養基中預培養90min后脫水。綠色巴夫藻冰凍前後的存活率都有提高，最大可提高5 % 。 -
Through two group tests on clayey soils with different water contents under quick - soaking, slow - soaking, freezing - thawing, different stresses ; the following studies were performed : the relationship between mechanical strength and microstructure dynamic environmental energyfield of clayey soil ; the interrelation between the microstructure dynamic environmental energyfield ; changing of external environment and medium environmental intrinsic of clayey soil
摘要通過兩組不同含水率的黏性土分別在快浸、慢浸、凍融、不同應力條件下的試驗，討論了黏性土力學強度特性與其微結構動態環境能場的本質關聯，分析研究了黏性土微結構動態環境能場、外部環境條件變化與其內在介質環境變化之間的密切關聯。
