And because, as you know, the traditional media is still heavily controlled by the government, social media offers an opening to let the steam out a little bit. 因为传统媒体还在政府的强力控制之下,社交媒体提供了一个开放的平台进行了一些(民众观点的)分流。
Most people know electricity standing still is no more useful than is a stationary belt between a steam engine and a machine to be driven. 大多数人认为,停滞不动的电并不比架设在蒸汽机和要被传动的机器之间的固定带更有用。
And four of its water-pumping stations still run on steam power. 其中的四个抽水站依旧是依靠蒸汽运作。
Due to the limit of resources and history problems, firepower equipment still dominates the market, which consists of fire station boilers, steam turbines, turbine generators and supplementary equipment. 由于资源条件和历史问题的制约,我国电力生产目前仍以火力发电为主,火力发电设备主要包括电站锅炉、汽轮机、汽轮发电机三大主机及其它辅助设备。
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。
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。
However, slight temperature difference still exists in the same cocoon cooking machine due to different locations of water or steam pipes and different water flow. 同一煮茧机因进水管、进汽管的位置或出水量的不同,温度略有差异;
So far, hydrogen is still mainly produced from steam reforming of fossil fuel or gasification of coal while hydrogen formed in sustainable manner, such as electrolysis, takes only small part of that. 目前为止,氢气的主要来源仍然是将天然气等化石能源通过蒸汽重整或者气化的方法来获取,而通过电解水等可持续方式制取氢气只占很小的一部分。
There is still a "false level" phenomenon for the evaporator water level change, meanwhile it is severely affected by the interference of external factors, such as water pressure and steam pressure. 并且蒸发器水位变化还存在着虚假液位的现象,同时还严重地受到给水压力和蒸汽压力等外界因素的干扰。
At present, there are still many special problems about nonlinear dynamics should be resolved to put ultra-supercritical steam turbine into operation. 发展超超临界汽轮发电机组目前还有许多特殊的非线性动力学问题亟待解决。
