課題的重點放在非致冷微測輻射熱計焦平面陣列，這種非致冷紅外產品的設計研製工作包括：設計和模擬工具的研究、材料選擇和器件製作工藝的研究、探測器和讀出電路的設計研究、真空封裝和性能表徵的研究等。This paper has analyzed twenty - year climatic data of typical cities in cold area, carried on lots number of field investigations and e xperiments, and systematically discussed improvement strategies for indoor physical environment of the ground floor room of residential buildings. though investigation of its thermal, sound and lighting environment it ' s found that there are many problems in this kind of room. those are : seasonal wetness, mold and fungus growing, destroyed structure and furniture etc, insufficient illumination, and bad ventilation condition
得出寒冷地區住宅底層室內熱環境、聲環境、光環境的實際狀況，結論表明，寒冷地區住宅底層存在的問題：季節性潮濕，高濕度導致黴菌生長、繁殖，潮濕的室內環境，導致建築物維護結構的內表面受潮起鼓，引起結構破壞，室內傢具、電器、物品的損壞，使得室內的衛生狀況、人體健康都受到影響：採光的明顯不足、通風散熱能力較差等。These results show that since the existent defects of combustion device structure and its hypothetical circle of contact, these make a poor primary and secondary wind rigidity in operation and a too big actual circle of contact. in addition, the coal used is extreme prone to burn and reside in boiler. under such a condition, the coal powder ignites earlier in a short time and short distance when it leave the jet - combustioning device, and splashes the water cooler, eventually this results in a burned coal residue in boiler
針對宏偉熱電廠410t / h燃煤鍋爐嚴重結渣問題，對燃煤的結渣性、爐內溫度工況及空氣動力工況等進行實驗研究，由於燃燒器結構和假想切圓選擇的缺陷，使得鍋爐在正常運行時，一、二次風剛性較差，實際切圓過大，加上目前燃用煤質屬于極易燃、易結渣煤質，致使煤粉在離開噴燃器很短的時間、較短的距離內開始著火，並沖刷水冷壁，最終造成爐膛結渣。Unlike many competitors ' designs, the " clc " system does not utilize internal circulation of the dirty sewage water for cooling, thereby eliminating motor overheating and premature failure caused by clogged cooling passages
與其它競爭者的設計不同的是， 「 clc 」系統並不採用內部循環的污水進行冷卻，因此就避免了電機過熱和冷卻通道被堵塞而導致的電機過早損壞。Investigation of ferroelectric thin films uncooled pyroelectric infrared sensors
鐵電薄膜熱釋電非致冷紅外傳感器研究Then, current perception threshold system is discussed in details including three main aspects : physiological background, theory of udtr and forced choice method and experiment basis providing the evidence for us to substitute heating, cooling and vibration signals with 5hz, 250hz, 2000hz sine current signals, respectively. the most important part of this thesis is the design of the system
然後詳細論述了定量電流感覺測量系統的理論基礎，包括三個方面：生理學基礎；閾值檢出演算法（ udtr和forcedchoice方法）的理論基礎；實驗基礎，即大量實驗表明， 5hz ， 250hz和2000hz的正弦交流電流刺激分別可以代替加熱，致冷和振動信號。In this paper ， first, the author drew some important conclusions by analyzing several technical factors and experimental conditions which would have great influence on the quality of diamond thin films during mpcvd process ， including gas proportion ， the power of microwave ， the plasma ' s location, the nucleation technique, etc. finally ， the author has successfully deposited nanocrystalline diamond thin films with 300nm crystal particles on the slick surface of silicon by using ch4 / h2 gases in the mpcvd system ， and the nanocrystalline diamond thin films was proved to have good field emission performance. all these researches will make the foundation for the field emission cathode of diamond films
本論文中，作者分析了mpcvd方法中氣源成分比、微波功率、等離子體球的位置、成核技術等各種工藝條件對金剛石薄膜質量的影響，並總結得到了一些有意義的結論；同時，在自行研製的mpcvd沉積系統上，於4 - 7kpa 、 1000左右的熱力學條件下，採用ch4 / h2氣源氣氛在光滑的硅襯底上制備出了晶粒尺寸在300納米以下的納米晶金剛石薄膜，測試得到了較好的薄膜場致電子發射性能，為金剛石薄膜場致發射冷陰極的研究工作打下了實驗基礎。Fan and water pump in traditional cooling system are controlled by engine directly and this fixed control pattern restricts flexibility of engine in different working status specially in execrable working status overheat of cooling system resulting in engine abnormality ; in order to change this condition, electromotion of cooling fan has been studied prophasely, further more good effect is acquired. on the base of it, the paper expatiates on the research on intelligent control of cooling water pump
傳統冷卻系統的風扇和水泵皆由發動機直接控制，固定的控制模式限制了發動機在不同工況下的適應性，尤其是在惡劣的工況下冷卻系統過熱導致的發動機異常；為改變這種狀況，冷卻風扇的電動控制已經進行了前期研究，而且取得了良好的效果，在此基礎上，本文又對冷卻水泵智能控制的研究進行了詳細地闡述。Besides introducing some different ways of readouting the signal of detector pixel, the principle circuitry of the whole array is also put forward. and a kind of temperature compensated load circuit is put forward to improve the offset correction and the gain correction for non - uniformity
