To prolong the life of high - speed steel tool by subzero cooling 15钢组织性能的影响
It was icy , zach ; it was subzero 结果很糟糕, zach门儿都没有
Research into the technology of subzero treatment in magnetic field for steel 4cr 13钢磁场深冷处理工艺研究
Depression of the pour point of diesel oil and improve its fluidity in subzero 降低各种柴油的冷凝点和冷滤点,提高其低温流动性。
In some parts of united states and russia , the winter season brings subzero temperatures 在美国及俄罗斯部份地区,冬季的温度都降到零度以下。
Yao and t - mac are cold from the floor . . . might have something to do with the subzero temperature outside the building and how cold it probably is inside the target center 姚明和麦迪在场上手感都非常的冷,或许和球馆外面0度以下的温度有关吧,标把球场的室内温度究竟有多么冷?
Our company endeavors to quenching & tempering , normalizing , tempering , high and medium temperature quenching , mesh belt furnace quenching , carbonizing , aging subzero and high temperature heat treatment , etc 本公司是一家致力于从事调质、正火、回火、高中温淬火、网带炉淬火、渗碳、时效冰冷及其高温热处理的厂家。
Since last week the situation has become more desperate because of an earthquake on thursday that has left thousands homeless in subzero temperatures and has killed more than 5 , 000 persons . the earthquake area is neighboring the famine area 上个礼拜,由于星期四地震的关系,阿富汗的情况变得更糟,震区有五千多人死亡,成千成万的人在零度以下的低温无家可归,地震灾区和饥荒地区相邻。
Nevertheless , the water evaporation from the water bath , condensation on fabric surface and vapor transmission through the fabric is greater and the moisture vapor resistance smaller under the subzero ( - 20 ) climate than those under the conventional ( 20 ) climate 在低温环境下( - 20 ) ,水浴的水气蒸发率(模拟人体出汗) 、织物水凝结率和透过织物的水气蒸发率大,织物湿阻小,表明了织物表面湿阻与环境湿度是相关的。
Antifreeze proteins ( afps ) are special proteins that have the ability to inhibit ice crystal growth , which depresses the freezing point of body fluid , thereby allowing survival at subzero temperatures . afps are firstly found in polar fishes , and then isolated from insects and plants 抗冻蛋白( antifreezeproteins , afps )是一类能使生物体耐受低温的特殊蛋白质,首先在极区鱼类中发现,之后又从昆虫和植物等中被分离出来。
