Meanwhile , the paper analysis shortage of the methods commonly used heating insulating oil , investigate principles of traditional pid control and fuzzy control , integrats the advantage of two control algorithms , makes use of fuzzy + pid control algorithm to control insulating oil temperature , and has designed fuzzy + pid controller . through matlab simulation , validates that wavelet hard threshold vale de - noise method can effectively reduce the impact of random disturbance 同时,论文分析了常用加热绝缘油方法的不足,在研究传统pid控制和模糊控制原理基础上,综合两种控制算法的优点,在绝缘油介损测量系统中,提出采用模糊+ pid控制算法对绝缘油温度进行控制,并实现了模糊+ pid控制器的设计。
These produels are produced by the techniques same with chemical bonded non - sintered bricks with semi - silica raw materials , they have high strength , good heat insulating and alkali resistant properties , they are mainly applied to the zones of large - sized cement rotary kilns which are croded badly by alkali , for example , the input zone , preheater , three - windtunnel , and decomposing zone 本产品采用半硅质原料，以化学结合不烧工艺生产而成，它具有强度高、隔热效果好、抗碱侵蚀能力强的特性，主要用于大型水泥回转窑筒入料区段、预热器、三次风管和分解带等碱侵蚀严重的部位。
Our factory succeeds in developing the new - type lightweight solid aluminium buckle - panel through practice for many years . this kind of metal buckle - panel includes double - sided panel body with one side of the buckle - panel as the bayonet connector , another side as the bayonet , lightweight filling material inside the panel body , fireproofing material filled inside the fireproofing metal buckle panel , possessing better strength of panel body , resulted in sound insulation , heat insulating , more ideal surface luster of the heat insulation panel body and no mechanical veins , beautiful appearance and difficult deformation 本厂经过多年实践成功研制新型实心金属扣板，此款金属扣板包括双面的板体，板体的一侧为卡接头，另一侧为卡口，板体中间带有轻质填充物，防火金属扣板中间另注防火材料，具有更好的板体强度，隔音隔热保温板体面光泽更加理想无机械纹，外形美观难变形。
After a discussion of the heat transfer condition of the chilled water pipe which is installed in tunnel , the relation between the temperature of the chilled water and its transportation distance , the author holds that a central refrigeration system shall be adopted , and the loses of chilled water temperature in a long transportation distance could be overlooked on the condition that the pipe is heat insulated 摘要分析了冷冻水管沿地铁区间隧道敷设时与周围环境的换热状况；认为采用集中供冷的方式，在隔热情况下可不?虑冷冻水因长距离输送而引起的温升损失。
We have put large amounts of money on scientific research and acquired enviable achievements . our company is the first state - run enterprise that invents metal shell heat eliminating technology , heat insulating mattress and multi - stabilizer driving technology to solve the heat eliminating problem of high - power energy saving lamps . we produce various types of energy saving lamps from 3w - 240w , which are widely used to instead of industrial lighting lamps like metallic halogen lamp , sodium lamp and auto - stabilized high - pressure hydrargyrum lamp . our company has passed the iso9001 : 2000 quality certification 圣路电器是一家专业生产大功率节能灯的高素质公司，在科研开发上进行了大量的投入并取得了卓越的成绩，率先发明金属外壳散热隔热空气垫及多镇流器推动技术，很好的解决了大功率节能灯的散热问题，可生产3w240w的各型节能灯，广泛用于替代金属卤化灯钠灯自镇流高压汞灯等工业照明用灯。
