With the impact test of conditioner airport and anti - dust mesh settings on heat exchange gas flow, the paper illustrates that the improper design may reduce gas flow, influence the refrigerating capacity of the system, and increase energy consumption
摘要通過空調風口及防塵網設置對換熱氣流流量影響的測試，結果表明，若空調風口及防塵網設計不當，則可能造成氣流量減少，並影響系統製冷量，增大能量消耗。Keep dry with good wind and rain gear : your body loses heat three times as fast when it ' s wet
準備良好的防風/雨裝備保持乾燥：要知道當身體潮濕時你體內熱量損失速度會比平時快三倍。So there is significant interest for the development of " optical limiter ", which strongly attenuates intense optical beams while exhibiting high transmittance for low - intensity ambient light levels, and therefore protects human eyes and optical sensors from intense laser pulses. the lack of appreciate nonlinear materials has been a significant barrier in the development of such devices
但隨大能量、高功率、短脈沖激光器的日益增多，激光傷害人眼和光學儀器的現象也隨之增多，激光威脅已成為不容忽視的現實問題，激光防護材料和激光防護器件也因而成為當今的熱門課題。Analysis result of simulation shows : underground commercial streets and atrium can use natural filling. in the actual engineering, mechanical smoke exhaust system is used by the local fire department added. the night club uses a set of mechanical smoke exhaust system, and the quantity of supply air can ’ t be less than 50 percent of the exhaust
模擬研究表明:地下商業街和中庭可以採用自然填充，在實際工程中當地消防部門在中庭增設機械排煙系統，以加快熱煙氣的排放;夜總會採用機械排煙，補風量不應小於排煙量的50 % 。This part emphasizes the synthesis of nanoarrays, aiming at controlling the size and distance of nanocrystallites using calixarene derivatives by altering the size, length and chemical structure of the organic molecules ; 2. this part emphasizes in situ synthesis strategy for fabrication of polymer network of zns based nanopowder, aiming at size controls, coating and preventing agglomeration following " one - pot " synthesis ; this method fits to low cost, large scale production ; 3. according to development in zno nanomaterials, we first report on the synthesis, characterization of amorphous zno, aiming at describing the principles and approaches of synthesis techniques, optical properties, spatial structure and doped effect ; the amorphous zno displays cage - like structure, showing a strong ultraviolet emission while the visible emission is nearly fully quenched, a potential uv - emission material ; 4
本論文以量子結構自組裝為出發點，提出利用杯芳烴及其衍生物的化學受限反應實現尺寸可調半導體納米粒子自組裝；提出有機聚合網路原位組裝zns基納米熒光粉方法，把熒光粉的納米化、包敷、防團聚在「一鍋」反應中完成，適于低成本，批量生產；根據當前zno的研究情況，我們首次合成了非晶zno ，研究了它的光學性質，確定了它的結構，並對其摻雜進行了初步的研究，非晶zno表現出強的深紫外發光特性，而可見發射非常弱，是一種有巨大潛在應用價值的深紫外發光材料；利用非晶zno的亞穩特性，對晶化過程中非晶zno納米晶zno三維受限量子結構特性，界面特性進行了深入的研究；利用固相熱分解一般受擴散控制特性，實現了尺寸可控的zno三維量子結構的自組裝；利用非晶zno的高度分散性，容易均勻成膜特性，實現了非晶籽晶誘導低溫液相外延自組裝生長高取向zno晶體薄膜。分享友人
