In order to analyze the degree of people's attention to different clothing parts under the condition of clothing fit evaluation, this paper takes different fit criteria of women blouse as the research object. In this research, subjective questionnaire evaluation experiment and eye tracking experiment were conducted respectively. By analyzing the subjective evaluation results, participants have the ability to correctly evaluate the comfort of clothing and further conduct eye-tracking experimental research. Moreover, eye -tracking indexes data such as fixation duration and fixation counts of 20 areas of interest of 15 blouses with different fit degree were obtained through eye-tracking experiment. Then the mean values of eye-tracking data of different fit degree and areas of interest were compared and multivariate analysis of variance was conducted. And the heat map which can present the duration of fixation in the areas of interest was analyzed. The results showed that the total duration of fixation and the fixation counts of participants in different areas of interest were significantly different. and the degree of attention paid to the clothing parts of the women blouse was the bust, shoulder, waist and sleeve when evaluating clothing comfort with different fit criteria. This paper has scientific reference significance for improving the method of pattern making and women blouse comfort. Keyword: Eye-tracking experiment, Fit criteria, Women blouse, Fit evaluation, Area of interest.

Surface texturing under fluid lubrication has been effectively used to improve the tribological performance. However research on the ‘secondary lubrication effect’ in the later stage of fluid lubrication is scarce. This study aimed to examine the friction reduction mechanism of the ‘secondary lubrication effect’ under fluid lubrication and to investigate factors that affect the effect. Lubrication models were developed under fluid lubrication. Friction force and hydrodynamic pressure of the lubricant were analyzed. Furthermore, the texture's oil-storage and -release capacities which may affect the ‘secondary lubrication effect’ were studied respectively. The results showed that the ‘secondary lubrication effect’ reduced friction by generating hydrodynamic pressure. The friction force in the later stage was higher than that in the early stage of fluid lubrication. The decrease in friction caused by the ‘secondary lubrication effect’ decreases in proportion with the loss of the lubricant. The lubricant infiltration capacity will affect the ‘secondary lubrication effect’ by influencing the texture's oil-storage capacity. Additionally, the release mechanism of the lubricant inside the texture was also obtained. Texture depth had a significant effect on the‘secondary lubrication effect’ by affecting the texture's oil-release capacity.

There are three typical representatives of U-shaped selforganizing production line, namely U-shaped Travelling, ChasingOvertaking, Cellular Bucket Brigade. The equipment, placed according to the process sequence, and the distance between the equipment form a Ushaped production line configuration. The former forms the process imbalance variable, and the latter forms the aisle width variable. For this, a simulation experiment with process imbalance and aisle width as independent variables and production line capacity as dependent variable was designed. The Plant-Simulation® simulation platform was used to obtain experimental data and verify it. The results show that ChasingOvertaking capacity is the highest under the same conditions. The production capacity of Cellular Bucket Brigade line and U-shaped traveling line is lower than that of CO line by more than 20%; and under the discrete system, the three self-organized production lines are not affected by configuration factors.
