But the steam engine still changed the world. 但蒸汽机仍然改变了世界。
Though most modern dwelling houses are equipped with bathrooms nowadays, the steam bath is still very popular. 现在,虽然大部分的现代化住宅都带有洗澡间,但是蒸汽浴仍然十分普遍。
At present, the study and application on conventional steam with medium-temperature dehumidification drying is preparatory, but the optimization of high-temperature dehumidification with conventional steam still have a blank. 目前,我国对常规蒸汽-中温除湿联合干燥已经有些初步的研究和少量的应用,高温除湿-常规蒸汽联合干燥优化尚属空白。
Currently, the superheated steam temperature control system in most power plants still adopts the conventional PID cascade control scheme. A new superheated steam temperature control system design scheme is proposed in this paper, which tries to combine the advantages of both intelligent control and conventional control. 目前,大多数火电厂的过热汽温控制仍然普遍采用传统的PID串级控制方法。本文提出一种新型的过热汽温控制方案,力图集智能控制与传统控制的优点于一身。
At present the first phase, steam huff-puff, still stays. 目前大都处在第一阶段&蒸汽吞吐。
Adjustable Steam Seal can reduce steal seal abrasion between the moving parts and the still parts, remain small seal gap, and reduce the leakage Steam flow, while at the same time improving the heat efficiency and increasing the safety reliability of power unit. 可调式汽封可以减少动静部分间的碰磨造成的汽封磨损,保持较小的汽封间隙,使泄漏蒸汽量减少,提高机组运行热效率,同时,也能够增加机组的安全可靠性。
Coke formation and equipment fouling in steam cracking furnaces in the ethylene industry still remain a major operation problem. 在石油工业中,结焦一直是乙烯裂解炉存在的主要问题。
Since the introduction of steam boiler in 80s of last century, the steam boiler have gradually realized the localization, but the Dry-degree detection is still a manual test, detection is less efficient, dryness of control still remains in the original technical level. 油田注汽锅炉自上世纪80年代引进以来,己逐步实现了国产化,但干度检测仍然为人工化验,其检测效率低下,干度的控制仍停留在原来的技术水平上。
