To meet this requirement, low-temperature chambers or furnaces are often built to provide the needed range of temperature . 为了适应这种要求,常常修建低温箱或加热炉来提供所需的温度范围。
Silicone rubbers are used for both high and low temperature applications, since their properties change little with temperature . 聚硅烷橡胶因性能随温度变化小,故在高温和低温的场合都能用。
At low temperatures, the difference in population of atoms between two energy levels, which is the basis of maser action, is greater . 在低温下,作为微波激射作用基础的两个能级之间原子数的差别较大。
On charge, the counter-voltage or overvoltage of the battery could be so high as to restrict the charging characteristics at low temperatures . 充电时,蓄电池的反电压或过电压太高,以致限制了低温充电性能。
It is true, however, that some plants, particularly commercial peaches, will not thrive in all apple sections to low temperature . 不过确实有些树,特别是商品性生产的桃,由于低温而不能在全部苹果产区很好生长。
the adduct is isolated by evaporating the solvent and any low-boiling concomitants at low temperatures of the order of about-100 to -20℃. 在-100-20的低温下,将溶剂和低沸点成分蒸发掉而分离出加合物。
Cryogenic vessels - cleanliness for cryogenic service 低温容器.低温容器清洗要求
Learning from the rush , detached from such and such 为了伴你渡过这个低温的凌晨
