This article discussed the principle of physical cooling and meaning for development of the hydrogel paster . the hydrogel paster shows unique advantage and board application foreground comparing with drug cooling and traditional physical cooling 本文论述了水凝胶降温贴片物理降温的原理及开发的意义,通过与药物降温、传统物理降温方法的对比,显示了水凝胶降温贴片的独特优势和广阔的应用前景。
According to the study of this project , we discovered the perfluorotriethylamine , a environment - protection evaporative cooling agent , and carried through the research on the process of fabricating , thermal nature , and heat exchange experiment on the evaporative cooling transformer model 通过对相变降温的研究，我们找到了一种环保型的蒸发制冷介质? ?全氟三乙胺。对其制取过程以及其热物性进行了研究，并在蒸发冷却变压器模型上对其进行了换热降温实验。
Double disk stir cooler can accelerate evaporating moisture for getting low temperature with strong stirring of scraper in short time through water feeding , blast and convulsions ; meanwhile , it has definite function of rebirth and mixing for old sand , which makes it become the best device for old sand treatment of clay sand system 双盘搅拌冷却机，能在短时间内在刮板的强烈搅拌下，通过加水鼓风抽风，促使水分蒸发以达到降温的目的，同时对旧砂有一定的再生混匀作用，使其成为对粘土砂系统旧砂进行冷却的最佳装置之一。
I have therefore always concerned myself with how government manages these investments with an aim to increasing its value . i have previously expressed my concern about the tendency for various government departments to upsize rather than downsize in the face of economic slump . mr . tsang responded by saying at the press briefing after his budget speech , that he had already asked government departments where the " user pay " principle applies to freeze their charges 在预算案公布后的简报会上,曾司长在答覆本人表示关注政府部门在经济降温的时刻,不但不作节约,反而有逐渐不断膨胀的趋势时,表示已要求那些需要持著用者自付原则的收费部门,冻结收费,这种手法无疑是对症下药了。
Combined with the key project " the design of evaporative cooling transformers " of hebei province , the thesis not only carries out some theoretical explorations of the application on electrical transformers , but also presents the method on selecting coolants and studies the characteristics of the selected coolant . then it proposes the design method of the tank structure and cooling systems of evaporative cooling transformers for the industrial application 本文结合河北省科技攻关项目“蒸发冷却变压器的研究” ，对电气设备相变降温的理论进行了探讨，提出了蒸发冷却变压器箱体结构和冷却系统的设计方案；对冷却介质的选用和相关特性进行了研究；针对工程实际研制了一台容量为30kva的蒸发冷却变压器样机，并进行了相关实验。
Takes several energy saving measures for air conditioning system , nick a large capacity centrifugal chillers working with variable frequency nil capacity chillers , variable frequency and variable flow control on secondary pump water systems , cooling tower for four - pipe water system in winter , fan - coil unit for commercial peripheral zones aid all - air systems for interior zones , variable frequency control on supply and exhaust air fain , enthalpy control on fresh air cooling in winter and intermediate season 采用了多项空调节能措施：大冷量离心冷水机组搭配变频小冷量机组，二次泵变频变流量空调水系统，四管制风机盘管冬季用冷却塔换冷供冷设计，商业外区风机盘管、内区全空气空调系统，送风机、排风机变频控制，过渡季、冬季利用室外新风通风降温的焓值控制设计。
This projection takes into account the effects of aerosols which tend to cool the climate as well as the delaying effects of the oceans which have a large thermal capacity . however , there are many uncertainties associated with this projection such as future emission rates of greenhouse gases , climate feedbacks , and the size of the ocean delay . . . etc 这预计已考虑到大气层中悬浮粒子倾于对地球气候降温的效应与及海洋吸收热能的作用(海洋有较大的热容量) 。但是，还有很多未确定的因素会影响这个推算结果，例如：未来温室气体排放量的预计、对气候转变的各种反馈过程和海洋吸热的幅度等等。
