摘要磁力聯軸器中內外轉子間的隔離套是磁力泵實現無泄漏的主要零件，由於磁力聯軸器工作時，隔離套便處在變化的磁場中，則其內部將產生渦流，導致渦流損耗和傳遞效率降低。Successfully applied markov process to analyze the change of vegetation cover, and point out the change of vegetation transition is not a single markov process but a multi - markov process and also is a long term process. 9. the writer proved that under the 8km resolution, the markov process ca n ' t estimate the trend of land use by two term - data no matter it ' s sequence or at intervals. through analyzing the change of each vegetation area, the change of spatial data and the markov process, the main conclusions are : in plain of china western arid land, the desert area decreased and the oasis area increased, most of the increase represents extension of the traditional oasis
利用回歸方程對今後的植被變化情況進行了模擬預測，其結果具有一定的參考價值；南京氣象學院博士學位論文8 .將馬爾科夫過程成功地應用於中國西部干早區的植被變化分析當中，指出，植被的轉移變化不是一重馬爾科夫過程，而是一個多重的馬爾科夫過程;而且是一個步長較長的馬爾科夫過程; 9 .證明在8klll尺度下，馬爾科夫過程不能使用兩期的土地利用變化來預測土地利用的發展趨勢，無論這兩期的時間是連續的還是有一定時間間隔的;通過各類植被的面積變化、空間變化及馬爾科夫過程分析認為:中國西部乾旱區在平原區整體上荒漠面積減少，綠洲面積增加，綠洲的面積擴大主要表現在原有綠洲的擴大。It is concluded that a certain amount of diaphragm will reduce the distortion effect greatly, but on the other hand, even with a fairly great density of diaphragm, such as the ratio of diaphragm span to the greatest dimension of the cross section is as small as 1. 25, the distortion effect ca n ' t be neglected compared with the effect of rigid torsion
