  sliding resistance
Transient changes of sliding resistance correlate with changes in contact area and arise from shifts of contact population age.
      
The effects of the overaging were shown to result from the transformation of the interfacial microstructure, which weakened the crack-sliding resistance in the near-threshold regime and embrittled the interface in the high crack-growth rate regime.
      
The effect of thermal exposure on the shear sliding resistance of these composites was also obtained using a thin-specimen push-out test.
      
The sliding resistance analyzed for the different boundaries is lowest in the α/β boundary, and increases on the order of α/β?α/α≈β/β, which plays an important role in controlling the superplasticity of the alloys with various α/β phase ratios.
      
Comparisons have been made with predictions based on unit cell models, assuming the sliding resistance of the interface to be characterized by a constant interfacial shear stress.

According to the results of the boat model testa and the full-scale boat tests carried out in the test pools, the sailing resistances of the floating boat on water under different velocities are studied in this paper.Some suggestions are proposed to reduce the resistance. In order to study the sliding resistance of the floating boat in paddy field soil, a soil bin is built in which the tests are conducted.The results indicate that the sliding resistance is greatly reduced by the lubrication effect of a thin film plaster on the soil surface. The theory of liquid lubrication is introduced into this study.The data obtained from the soil bin tests are entered into the electronic computer and the regression analysis is made with a special developed program. A semi-empirical expression for sliding resistance of floating boats is presented. The measured and predicted values of the sliding resistance in soft paddy field soil are found in good correlation. The resistance coefficients presented in this paper can be used as the reference to predict the sliding resistance of floating boat under similar conditions.

船式拖拉机在深软水田中工作、或在河网地区为进行田间转移而在水中行驶时,船体是其主要的支承部件。本文根据水池试验得到的船模和船拖原型船体在不同前进速度下行驶阻力的试验结果,研究了船体在水中的行驶阻力,提出了降低阻力的途径。为研究船体在水田泥中的滑行阻力,研制了一条土槽进行试验。结果表明:田面有泥浆薄层时船体滑行阻力将大大降低。引入液体润滑理论对泥浆薄层的润滑作用进行了探讨,并用电子计算机对土槽试验数据进行回归分析,提出了船体滑行阻力的半经验表达式。船体在稀软田中滑行阻力的实测和预测值看来是相当一致的。文中列出的阻力系数值可供预测同类条件下的船拖船体滑行阻力时参考。
