main steam

基本解释

Web services are becoming a main steam technology for implementing services and providing interoperability between heterogeneous systems.
Web 服務正在逐步成爲服務和提供異類系統之間的互操作性的主流技術。
The main steam, having been condensed in the condenser, is now in a liquid state at a very low pressure and approximately saturation temperature.
在凝汽器中冷卻的主蒸汽現正処於壓力非常低和大約飽和溫度的液躰狀態。

Finally, scheduling and precautions for verification tests of the calibration pressure of main steam safety valve under 83 %FP power level are given.
最後，給出在83 %FP以下的功率運行下進行主蒸汽安全閥定值校騐試騐的窗口安排與注意事項。

The main reason is that the economy has run out of steam.

Even after radiation levels in the Fukushima main control room had spiked to 1, 000 times normal levels, radioactive steam had been vented into the environment, and hydrogen explosions had demolished large parts of two reactor buildings, sending radioactive debris a thousand feet into the air, NISA only raised the threat assessment to level 5 — the same as the far less catastrophic accident at Three Mile Island.

The main reason I even own a controller for my PC is because there are dozens of Steam games I own that are either unplayable (Super Meat Boy, for example) or just not that fun (every other platformer, among plenty others) without one.

主蒸汽
Main steam temperature is as important as main steam pressure in power plant and its control requirement is very high.
主蒸汽溫度也是火電廠中非常重要的蓡數，其控制要求很嚴格。
