  1. According to the operation condition, it is shown that the protector presented in this paper can duly follow the motor ' s load fluctuation and capitally match with motor ' s tolerance overload characteristic, thus it is valuable to be actually used

    運行結果表明，本文所研製的單片機式熱保護電器能較好地動態跟蹤負載變化，其熱保護特性能較好地與電動機的允許過載特性相匹配，有一定的工程實用價值。
  2. In view of this situation this article has conducted research to the design of metallurgy auxiliary biography with the frequency conversion table electrical machinery first multianalysis to the frequency changer and the frequency conversion table electrical machinery movement characteristic is carried out, the voltage waveform harmonious which the frequency changer outputs is big, attacks in a big way, and the voltage climbing rate reaches as high as 6600v / mu s which is 20 times ordinary sine alternating voltage, the rolling mill auxiliary biography table set the extremely strict request to the electrical machinery ; its movement frequency is very low, rate frequency in 8 - 20hz ; the velocity modulation scope is wide, the lowest movement frequency lowers to 1hz, and the starting number of times is quite frequently, each hour reaches as high as 600 - 800 time, the impact shoulders in a big way, the overload capacity request is high

    針對這一情況本文對冶金輔傳用變頻輥道電機的設計進行了系統研究。首先對變頻器和變頻輥道電機的運行特性進行詳細分析，變頻器輸出的電壓波形諧波大，沖擊大，電壓上升率高達6600v / s ，是普通正弦交流電壓的20倍;軋機輔傳輥道對電機提出了十分嚴格的要求:其運行頻率很低，額定頻率在8 - 20hz ;調速范圍寬，最低運行頻率低到0 . 5hz ，起動次數相當頻繁，每小時高達600 - 800次，沖擊負荷大，過載能力要求較高。
  3. In present thesis, the actual design theories and methods for super - low specific - speed pump are introduced first, including " the increased flowrate design method ", " the method of anti - hump on h ~ q characteristic curve ", " non - overload design method ", " the design method of complex impeller " and so on. according to these methods, 5 types of impeller have been designed

    論文首先對極低比轉數離心泵的現行設計理論和設計方法作了介紹，包括加大流量設計法、減小或消除揚程曲線駝峰的途徑、無過載設計及復合葉輪設計法等，並按照這些方法設計了五種葉輪。
  4. First super - low specific - speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low ; secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. therefore the h ~ q characteristic curve is often hump - shaped, and at the low - capacity operating condition the instability often occurs ; thirdly the centrifugal pump at high - capacity operating condition is easy to overload because the n ~ q curve appears a rising trend

    首先由於它的揚程較高、流量較小，所以它的流道狹長，圓盤摩擦損失較大，效率相對較低；其次由於它的流道擴散較嚴重，易在葉片進口產生迴流和在出口產生脫流，揚程流量特性曲線易出現駝峰，在小流量工況下易產生不穩定現象；第三，由於其功率流量曲線呈現上升趨勢，在大流量區運行時電機易過載。
  5. The most important characteristic of real - time application systems is that they must receive and respond to a set of external stimuli within rigid and critical time constraints referred to as deadlines, otherwise, a overload fault will probably result in a catastrophic event

    實時應用系統的特點是，它們應該在嚴格的死限限制范圍內對一系列的外部事件作出響應，否則，系統的過載就可能會導致災難性事件的發生。
  6. In this thesis, we study the basic structure, principle, realization, characteristic and the main application fields. to deal with overload problems aroused by the variety of input data rate, we discuss the method of constructing load management system, further more study particularly the key technology of load - balancing, load - shedding and data summary

    論文討論了數據流系統的基本結構、工作原理、實現方法、特點以及其主要應用領域，針對由單位時間內輸入系統的數據單元數量變化引起的處理器過載問題，探討了負載管理系統模型的構建方法，並對負載平衡、 load - shedding 、摘要生成等關鍵技術進行了深入研究。
