此时调节级后压力11.6Mpa、温度484.0℃，主蒸汽流量为910.2t/h。假设调节级的反动度为零，主汽门和调节汽门的压力损失为主蒸汽压力的3.0%，且在调节汽门顺序开启时无重迭度。试计算：

(1) 对应于调节汽门全开时单个喷嘴组通过的最大流量。

(2) 在不计调节级后温度变化情况下，调节汽门顺序开启时各阀点的流量，并画出各阀点处各调节汽门的流量分布图。

(3) 如果调节级的效率保持不变，由调节汽门顺序开启时调节级热力过程线，估算各阀点处调节级后的温度值，由此估算考虑调节级后温度变化时各阀点的流量变化。

(4) 分别计算出额定工况(5个调节汽门(全)开启时)和3个调节汽门(全)开启时调节级的部分进汽损失，画出这两种情况的调节级动叶的速度三角形，并对计算结果作分析、讨论。

(5) 在主蒸汽流量为750t/h时，计算出各调节汽门中的流量分配和调节级后温度与焓值，以及部分开启调节汽门后的蒸汽压力。

rass-roots governance according to law is an important foundation for promoting the construction of rule of law, but also the most basic development environment. Despite my good social order in General, but there are law-abiding consciousness, social order is not standard, regardless of faith, Twining visit visit and other outstanding problems. We want to actively promote the field of multi-level governance according to law, promote the continuous improvement of the social environment. To promote universal compliance. Actively foster the rule of law culture, carry out law publicity and education on honesty and trustworthiness, guide the masses and consciously abide by the law, failing to find method, problem-solving method, method of gradually changing the world, he is not looking for but someone %ules\w law, abide by the good atmosphere. o strengthen the comprehensive management of public security. Deepening peace xingan construction, strongly

against violence crime, mafia and serious criminal offences, to protect the legitimate rights and interests of citizens, legal persons, carry out criminal policy of temper justice with mercy, the maximum stimulating social vitality, and earnestly safeguard social harmony and stability. o resolve social conflicts by law. To further smooth channels of reporting social conditions and public opinion, improving regulation, arbitration, as well as dispute resolution mechanisms, implement fully the petitioners ' cases \-party\ngs and supervising system of letters and calls, and to resolve the involved law lawsuit into the orbit of rule of law, vexatious, Twining visit visit, disturbing social order and other malicious extortion, resolutely crack down. Five, improving cadres Vitale, provide strong protection for forest development XI General Secretary stressed that the comprehensive revitalization in Northeast China, needs a high quality, solid style, cadres of the dare to play. Cadre cadres is a pledge, should want to do work and able to do good, enthusiasm is paramount. Treat party cadres, it is necessary to Strict management, and warm care, enable the broad masses of cadres work hard work, this is two parallel principles. In strict accordance with the standards of good cadres selection and appointment, the real officers, dare officers, those who want to play, good as excellent cadres at all levels of leadership in the past. At present, some leading cadres work initiative is not high, beyond political, idle, lazy governance governance, not as, slow, messy and a phenomenon still exist to varying degrees, affected and restricted economic and social development. We must mobilize the enthusiasm of cadres as an urgent task, adhere to combination of incentives and constraints, and adhere to the strict management and warm care, practical solution \s not to\oblem, motivate cadres and better lead the masses to an undertaking, the cadres and create the new achievement in a dare to play, good at shows as new. To identify the problem, accurate pulseof law to visit and contribute to make visits to the vexatious visits arrogance. On these issues, we need to have a proper understanding, should take the lead to establish a sense of fear of the law, strengthen the application of the rule of law and the rule of law work of thinking and take up responsibility for the construction of the rule of law. Put learning first. Premise is ignorant of the law, abide by the law. Leading cadres at all levels should take the lead in studying the Constitution and laws and regulations closely related to work assumed by, an accurate grasp of the basic position of our party to address the issue of the rule of law, known for the scale to do things, figure out how to use it right, what things do, what not to do, it can never \areness of the rule of law.

Should take the lead to abide by. Fulfil its mandate in strict accordance with statutory authority and procedures, no matter what you want to adhere to the law, thought of rule by law and the rule of law to tackle hot issues, effective statutory duty must be, without authorization, is not available. Such as construction areas, some cadres are because there is no procedure is followed by the rules, paid a heavy price, we should learn from them, in strict accordance with the law on bidding and implementation ... Promised to give preferential policies for enterprises, hesitant to cash or cash not at all. Masses feel strongly about these issues, it is necessary to be solved. o accelerate decentralization.
