摘要根據近幾十年來放牧強度對綿羊放牧行為、採食植物組成和生產性能的影響進行了綜述，得出以下結論：綿羊的個體增重與放牧率之間呈線性負相關，而公頃增重與放牧率之間呈正相關；綿羊的採食量隨著放牧強度的加重而降低；放牧強度對母羊繁殖性能各指標影響差異不顯著；隨著放牧強度的加重，綿羊的採食時間增加，遊走、反芻臥息時間減少；每百口採食量和日採食量減少，而採食速度增加；放牧綿羊的嗜食性是相對的；輕牧有利於提高肉的品質，但是產肉量低，總的經濟效益不高。Offline control strategy refers to work under known load condition, according to the load condition calculate the instruction voltage, then store them in the datasheet, each time read the instruction voltage from the datasheet, when input dc bus voltage changes, a pi controller is used to adjust the instruction voltage thereby fix the output voltage rms
離線型控制是指在已知負載的情況下，計算出控制用的指令電壓，存在數據表中，每次讀取表中的數據，當輸入母線電壓變化時通過pi調節調整指令電壓來控制輸出電壓。由於計算量不大，用單片dsp就可以實現指令電壓的計算和svm演算法，主要用於負載情況已知且固定的場合。Because of forecasting reactive load at first, it can detect the change of voltage at low - voltage bus from the change of reactive load or the change of voltage at high - voltage bus, then it can decide that adjusting transformer tap or capacitor switch, and avoid blindly and deficient adjusting. on the condition the reactive power is balanced and voltage qualified, it can realize the switching times of loaded taps and capacitors being efficiently decreased
由於預先預測出無功負荷，提前了解了無功功率變化的趨勢，可以有助於判定低壓母線電壓變化是由無功負荷變化引起還是由高壓側電壓變化引起，從而適時決定是調有載調壓變壓器分接頭還是投切電容器，以此避免了盲目和不充分的調節，實現在保證無功基本平衡和電壓合格率的前提下，減少有載調壓變壓器分接頭的調節和並聯電容器組的投切次數。With the development of the electrical power enterprise and computer technology, it is important to design a highly efficient ， better maintainable and graphic interface based software package for power system analysis and computing in the paper ， the author put forward a kind of new sensitivity analytical method which take into account load characteristic to fix on the weak bus, and with example to prove the exactness of the algorithm ; developed the visual electrical power system analysis and computing and graphic sporting system, the software package was developed by using the idea of object oriented programming ， the method of class ' s inheritance ， polymorphism and virtual function, and set up equipment - chart element - the interreaction between class this make it easy to expand, maintain and replant
