Two kinds of thermal residual stresses exist in metal matrix composites. One of them is temperature gradient induced thermal stresses caused by temperature gradient in MMC. The other can develop upon cooling from the processing temperature to room temperature due to the coefficient of thermal expasion mismatch between the fiber and matrix and is called CTE mismatch induced thermal stresses.

金属基复合材料有两种形式的热应力,一种是在MMC中由于温度梯度引起的热应力,即温度梯度诱导的热应力;另一种是在冷却过程中由于基体金属和纤维的热膨胀系数不匹配引起的热应力,即热膨胀系数不匹配诱导的热应力。

The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.

Analyses of the EAWJ seasonal variation and the atmospheric meridional temperature gradient in the mid-upper troposphere indicate that the EAWJ center always corresponds to the largest meridional temperature gradient in the mid-upper troposphere, suggesting that the seasonal variation of EAWJ is a response to the meridional temperature difference.

分析急流与对流层中上层经向温度梯度的季节变化发现,急流出现的位置总是对应着经向温度梯度较大区域,急流中心有随气温南北差异大值中心移动的趋势,急流中心与最大温差中心相对应,表明急流中心的位置变化是对气温南北差异季节变化的响应。

The temperature gradient is larger in case ofussual half-zone model which has a uniform temperature distribution on the hot rod,andmodified half-zone model which has a non-uniform temperature distribution in the hotrod and negative radial temperature gradient near the axis of the hot rod.

模拟半浮区模型提出选择热传导系数与试验液体相当的材料作为热端棒材,使得热端内侧的轴向温度梯度接近于零。模拟半浮区模型的温度分布更接近于全浮区温度分布的一半。对于改型半浮区模型,选择热传导系数高于试验液体值一个数量级的材料作为热端棒材,使得热端温度分布不均匀,并且热端内侧温度高于外侧温度。
