These two men, of hard bilious natures both, rarely came into contact but they chafed each other's moods.
這兩個人都是氣質冷酷，易動肝火的，他們除了經常發生摩擦，是難得往來的。The results indicated that, the fabrication process of ultra - fine grain material is mainly determined by the stress, rotate speed and the flux of cooling water. the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of cooling water. compared with commercial ly12, the invalidate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of compression property ; and the abrupt change of the dilatability of the ultra - fine grain material at 500c is found ; also the phenomena of which the grain size of these microstructures is stable when annealed under 300c is observed
研究表明，採用本文提出的摩擦壓扭強變形區轉移法可以得到棒狀的超細晶材料，軸向壓力、扭轉速度和溫度是採用該方法制備超細晶材料的主控參數；試件的旋轉轉速和冷卻速度對變形區晶粒細化和硬化效果影響顯著；超細晶ly12的壓縮性能與淬火+自然時效狀態的ly12壓縮性能相比，斷裂強度和延伸率均有一定程度的增強；超細晶ly12的熱膨脹系數在550左右發生明顯的變化。A piece of rough paper is stuck on the side of the box, and when a match is rubbed against it, friction heats the head of the match, making it burst into flame
在火柴盒的邊上貼上張糙紙，當火柴與其相擦時，摩擦使火柴的頭發熱，使其燃燒起來。Summarizing and discussing the usual wear fault and wear kinds of the general mechanical equipment. engines of self - propelled gun are the main discussed targets, the component of the friction pairs and wear fault rules of which are analyzed. building the belter base for carrying out wear state monitoring further
總結和討論了一般機械設備常見的磨損故障和磨損類型，並以自行火炮的發動機為重點研究對象，分析其主要摩擦副的材料組成和磨損失效規律，為進一步實施磨損狀態監測奠下良好的基礎，討論了自行火炮潤滑油變質原因和機理。分享友人
