turnaround speed 解釋
周轉速度
  • turnaround : 1. 車輛調頭處;(思想、立場的)轉變。2. 回航[卸貨、加油、檢修、上貨]所需時日;來回。3. 小修,預防處理。
  • speed : n 1 快,迅速。2 速率,速度。3 (汽車的)變速器,排擋。4 (膠片,照相紙)感光速度。5 〈古語〉興隆...
  1. 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。
  2. They will short down the working life of air compressor because they are always started or stopped when we want to make the railway carriage stay in a fixed temperature. now, automatic and intelligent control systems are being applying in bus air - conditions control. in this way, computers control the work of air compressor, the turnaround speed of fan, the open degrees of wind controlled doors and so on

    我國大多數客車空調仍然採用簡單的壓縮機開關控制及循環離合控制系統,如:離合器?熱力膨脹閥系統( cctxv )和離合器?節流管系統( ccot ) ,這些控制方式的精度低,當進行恆溫控制時壓縮機處于頻繁的開、停狀態,縮短了壓縮機的工作壽命。
  3. This controlling way can make the passengers feel much comfortable and make the bus air - conditions work with a high efficiency. in this thesis, a single - chip microcomputer fuzzy controlling system with mcu : at89c51 is designed to deal with the bus whole air - condition composed with refrigerating system and heating system. via controlling the open of temperature door, turnaround speed of evaporator fan and subsidiary engine, it can control temperature of railway carriage

    本論文針對獨立式全空調型(完全合一型)客車空調系統,設計了一個以at89c51為核心的採用模糊控制演算法的嵌入式單片機控制系統,通過控制溫度門的開口角度、蒸發器風扇的轉速、輔助發動機的轉速來控制車廂內的溫度,通過壓縮機的開、停對蒸發器除霜,系統具有溫度顯示、用戶設定的分擋多級溫度控制、在線控制參數修改等功能。
  4. The more unfavorable assets the bank has, the slower the turnaround speed of loan bankroll will be, the more bankroll will be needed to produce ration of supply, so there would be more supply for loan currency and more pressure of gross social demand. however, the excess of liabilities on loan over net assets actually means the enterprise has consumed residents ' deposits in the form of practicality but failed to do the substantial compensation, which also means this part of deposit the urban and country residents hold go up in somke

    銀行不良資產越多,周轉速度較慢的貸款將越甚,糧食供應將需要更多的貸款周轉,因此會有更多的貨幣供應量和貸款的壓力,更加嚴重的影響社會需求.盡管如此,超額的貸款負使得企業凈資產被耗盡,實際上就是居民存款的形式,但沒有做大量實用性補償,這也意味著這部分城市、全國居民存款瞬間耗盡
