  3. Regarding the hysteretic properties and time - varying of the system, the scan round performance of the controller, adopt incremental pid algorithm in constant - pressure controlling and combine it with the integral - separated dead - zone algorithm as appropriate for the situation of the measuring system and applies fuzzy self - tuning to control pid controller parameters

    由於系統的滯后時變性和控制器的循環掃描工作方式，恆壓控制採用增量式pid控制演算法，結合測量系統實際情況加入積分分離帶死區改進演算法，並對pid參數進行模糊自整定控制，設計了一種參數自整定模糊pid控制器。
  4. To search for high - velocity molecular emission toward massive star formation regions, and to study the connections between h2o masers, iras objects and outflow properties, we carried out a co observation for a h2o maser sample. we found that most of the objects have excess high velocity emission produced by outflows ; we find a significant correlation between co line full widths and iras luminosities. the widths are proportional to the iras luminosities

    通過在大質量恆星形成區搜尋高速分子輻射，並且研究它們與星際h _ 2o脈澤源和所聯系的紅外源之間的關系，我們發現絕大多數源都存在著氣體的高速運動並且它們是由分子外流產生的；我們同時發現在co分子的譜線全寬和所對應源的紅外光度之間存在很好的相關性，線寬隨紅外光度增加而變大。
  5. In the study, what ' s more, some particular experiment phenomenon are explained by means of theories, such as water move, the change of water and ice. in the test, the preliminary propagation of the hard rock containing a small mount of aperture is dominant during the test, inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, because the circle time is limited, the damage propagation can not be observed during enough times

    試驗發現，對于強度較大，顆粒孔隙閉合程度較高時最初的幾次凍融循環對損傷的擴展起著主導作用，而後逐漸趨于恆值;而對于強度較低，孔隙貫通程度較高，離散性較大的軟砂巖，隨著凍融循環次數的增加，損傷變量增大，由於本次試驗凍融次數有限，未能觀察到凍融循環次數較高時的損傷變量變化情況。
  6. The pmma ' s craze damage is observed on line in different temperature and invariable load, which show that the change pricks up with the increase of time and temperature. with the disposal of the image, we get a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress. then the data from experiment is to match in non - linearity, pmma ' s density of crazing damage changing with time and stress is available

    對pmma在恆定荷載作用下，不同基溫下的pmma銀紋損傷進行了實時在線觀測，結果表明： pmma試件的銀紋隨持荷時間增加，而且隨著溫度的升高，可以加劇這種銀紋隨時間的變化；經圖像處理，得到了不同基溫下、不同應力水平下， pmma試件銀紋損傷面密度值；進而，對所得數據進行非線性擬合，得到pmma試件銀紋損傷密度隨時間演化規律，以及應力水平依賴性； 3
  7. Ptc heater uses the ptc heating sensitive resistance as the heating source. it is widely use in the air - conditioner, warm drier and warmer etc. as the secondary heating. the resistance value of the ptc heater will rise or reduce with the change of the environment temperature as it makes the ptc heater has the features of energy saving, even heating, safe and long life. it is widely welcomed by a lot of customers

    Ptc加熱器是採用ptc熱敏電阻元件為發熱源的一種加熱器，廣泛用於空調器的輔助加熱和暖風機取暖器等電氣設備上， ptc熱敏電阻元件因具有隨環境溫度高低的變化，其電阻值隨之增加或減小的變化特性，所以ptc加熱器具有節能恆溫安全壽命長等特點，被越來越多的用戶所歡迎。
  8. 2. according to the weighted average, soil co2 concentration is 0. 58 - 13. 29 times of that in atmosphere and is relatively lower than similar research, meanwhile, soil co2 concentration in profile varied irregularly, which possibly is due to the chemical and physical characteristic of loess soils, season change and arid climate etc. the variation of soil co2 concentration in profile is mainly controlled by soil temperature and soil moisture, in contrast with soil temperature, the control role of soil moisture is minor. in conclusion, in order to have a good command of the distribution and change rule of soil profile co2 concentration as well as its effect factors, multi - point and successive location experiment should be made, meanwhile establish indoor soil - pillar monitoring experiment

    土壤co _ 2的濃度約為大氣co _ 2濃度的0 . 58 ? 13 . 29倍與同類研究相比要低，這是與黃土的土質特性，觀測期又逢特別乾旱年制約了土壤微生物的活動，再加上土壤中有機質虧損，養分不足造成的；土壤co _ 2含量的變化是隨溫度的升高而升高，在夏季達最高值，冬季最低；在土壤co _ 2濃度變化的影響因子溫度和水分中，溫度的影響作用高於水分；土壤剖面co _ 2濃度隨著深度增加，總的變化趨勢是遞增的，但也有反復，甚至有的順剖面而下幾乎保持一恆值，這與季節變化和黃土自身結構的通透性以及在觀測期內的乾旱氣候等條件有關。
