劣化建築
英文
deteriorated building-
Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control
與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly - varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, in hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed
若這些海上建築物的上部結構底高程較低，在惡劣海況下當大波浪在其面板下面通過並與之接觸時，面板下面除了作用有強度變化較緩慢的波壓力外，在波峰剛接觸到面板時尚存在著歷時很短但強度極大的沖擊壓力，這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。Both old buildings and new constructures made of inferior material urge us to erect a set of perfect quality detecting and on - line monitoring system, ensuring people against danger and economy growth against failure
業已老化的舊有工民建築和層出不窮的新建建築的偷工減料、質量低劣迫切要求建築行業建立起一套完善的質量檢測和實時監控體系，以切實保證人民財產的安全和我國經濟建設的順利進行。With the quick boom of economy and the rapid development of construction, modem buildings call for better and better material than before. steel tube confined concrete ( stcc ) has been applied in building widely and has acquired economic benefit largely for its excellent quality in structure of big span, height, and loads, good quality of behavior in bad environment, fine gift in industrialization produce. so, it " s a good material of building
鋼管混凝土能夠適應現代工程結構向大跨、高聳、重載發展並滿足承受惡劣條件的需要，符合現代施工技術工業化要求；而且具有承載高、塑性和韌性好、施工方便、耐火性能和經濟高效等優點；因而正被越來越廣泛地應用於土木工程中；並已取得良好的經濟效益和建築效果，是結構工程科學的一個重要發展方向；有著廣闊的應用前景。分享友人
