It was hot in the studio, and drops of sweat stood on her forehead. 画室里很热,她的额头渗出了汗珠。
The results showed that the processing parameter of hot pressing has great influence on the tensile strength and bending strength, and the strength of composite material first increases but then drops with temperature increases. Strength is maximum when temperature is 170 ℃. 结果表明热压工艺参数对板材拉伸强度和弯曲强度都有显著影响,且随着温度升高复合板材强力呈先增大后减小趋势,在温度为170℃时,强力达到最大值;
When hot oil follows cool oil in process of batch transportation, the temperature drops fastest. Therefore, the key to ensuring batch transportation safety is to control hot oil temperature at entrance of the next station in transportation circulations. 当冷油(进口原油)前行、热油(国产原油)后行时,热油油头的温降幅度最大,控制各循环中热油油头的进站温度,是确保冷热原油顺序输送安全性的关键。
With the global economic recession, the world iron and steel industry is now in hot water: serious overproduction of steel, sharp decrease in steel demand, gradual drops in steel price, all these resulting in the fierce competition in international steel market. 目前全球钢铁业随着全球经济的衰退陷入低谷,钢材产量严重过剩,需求急剧衷退,钢价走低,国际钢材市场竞争空前激烈。
Desert area lies in the Chinese north, nature environment is worse, summer is very hot that the highest soil surface temperature gets about 70 ℃, and winter is very cold that surface temperature drops under-30 ℃. 沙漠地区地处祖国北方,自然环境十分恶劣,夏季炎热,地表最高温度高达70℃左右,冬季严寒,地表温度降至-30℃以下。
