在數值計算過程中，著重考慮了溫度變化與接觸區域壓力變化的耦合問題，接觸壓力與外加壓力的關系，以及分別改變一些參數對結果的影響。 - The fem results indicated that as to the rough surfaces in sliding contact , the value of the contact pressure was very high which coursed a high value of the heat flow rate , meanwhile the sliding time was not enough for the frictional heat to transfer , thus the highest value of the body temperature occurred just on the sliding surfaces , which possessed a sharp thermal gradient in direction perpendicular to the sliding surface . so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously , thus this change of the contact pressure would affect the temperature distribution in return
對于相對滑動的粗糙表面，因實際接觸面積小而導致接觸壓力很大，這樣使得熱流密度會很大，同時由于滑動時間很短，熱來不及傳導，最高溫度發生在摩擦表面，在垂直于摩擦面的方向有很大的溫度梯度，使得熱應力很大，且最大應力發生在表面，同時產生熱彈性變形，這種變形使得接觸區域內的壓力分布發生變化，這種變化又反過來影響了接觸區域的溫度分布。 - It's difficult to find frictional heat in a sentence. 用frictional heat造句挺難的
