New type of water chemistry for utility drum boiler and its principle and characteristic Two kinds of water chemistry's main principle and characteristic are detailedly analyzed. Against the problem of high eroding speed, high Fe content in feed water and boiler water, high scaling speed, short chemical cleaning interval, needing poisonous chemical deoxidant, etc for drum boiler's deoxidization water chemistry and difficulty of using oxidation water chemistry, a new type of water chemistry is put forward on the basis of analyzing the characteristic of whole power station's water steam cycle system, principle of two kinds of water chemistry and their practical effect in every cycle stage. Considering two water chemistry's merit, a new water chemistry called Limited Oxidation Water Chemistry is put forward, which is a local slight oxidization no-deoxidant water chemistry. And the proposed method's principle, control parameter, applying condition, start-lay up and emergency measures are initially calculated and analyzed.

It change the normal method for "beginning control" and "goal control". With the development of living level, upholster is dispensability for indoor, the using of decorative material produce plenty of poisonous、baleful chemical substance. These substance make the air indoor into bad, and threaten the healthy in the door if these cumulate .What"s more it will reduce work efficiency. The past method of IAQA is subjective assessment or giving priority subjective assessment. But people will adapt to indoor environment due to settle in the door long-term, which it lead to incorrectness. So, we can"t only use subjective assessment for IAQ. In this article, the author bring forward the best and the reasonable assessing method ,which it is combining the subjective assessment to objective assessment.

随着生活水平的提高，室内装潢成为家居装饰不可缺少的部分，装饰材料的应用，会产生大量的有毒、有害化学物质，使得室内的空气质量变差，且长期累积会威胁室内人员的身体健康，导致工作效率低下，过去对室内空气品质的研究仅用主观评价方法或以主观评价为主对室内人员的主观感受做调查，但是由于室内人员对室内的环境具有适应性，从而造成评价的不准确，且过去对化学微污染物的影响没有定性的研究，因此，用该方法进行评价显然是不准确的，所以，本文提出用主观评价和客观评价想结合的评价方法对室内空气品质进行综合评价。
