The unfavorable factors contain complicated production technology and wayward product quality, etc. first of all, on the basis of analyzing performance index of 3 - layer pe anticorrosion, technological process and operational environment, this paper advances the synthetic control schemes that have constant compound control of temperature and feedback control of speed. considering the production process of the 3 - layer pe, because it is affected by colloidized time of fbe, relatively strong coupling exists between the temperature and speed. through the rational matching and simplifying of the variable, the system realizes uncoupling
首先在分析三層pe防腐層性能指標、工藝過程及工況條件的基礎上，提出了溫度復合控制和速度反饋控制的綜合控制方案；考慮到三層pe生產過程中，由於受fbe膠化曲線的影響，溫度和速度之間存在較強的耦合，本方案通過合理的變量搭配，實現兩種變量的解耦；文中還依據傳熱理論、中頻感應理論等提出鋼管傳熱過程理論建模的方法，經實際驗證，表現出該方案和建模方法的科學性和實用性。 -
Applied constant keeper can enable the microorganism to continuously culture in double periods of “ constant flowing method speed ”. ? it has a process as such : according to the multiplying speed that the bacteria cultures in double growing periods, and the speed that it consumes the nutritious material, fresh culturing liquid is continuously added. ? at the same time, the same amount of well - cultured bacteria liquid is continuously drawn out, so that the next two items are kept relatively constant : the added material and the consuming material ; the amount that the bacteria have multiplied and that has been drawn out
應用恆化器，能使微生物以對數期「恆流法速度」連續培養，即根據菌種在對數生長期繁殖的速度和消耗營養物質的速度，不斷加入新鮮培養液，同時不斷抽出等量培養好的菌液，使加入物與消耗物、細胞繁殖量與細胞物質抽出量，保持相對穩定均恆。
