如果混凝土養護得很差，那麼在精心選定混凝土的級配、拌和和密實成型上所耗費的精力將是徒勞無益的。Aesthetic appearance is one of the most important criteria used by consumers in judging clothing wear performance. bagging is a kind of three - dimensional residual deformation that deteriorates garment appearance during wear and caused dissatisfaction. to understand the psychophysical mechanisms of fabric bagging perception, a method of subjectively evaluating this behavior is developed by using a series of photographs taken from bagged fabric samples. both ranking and rating scales are used as the psychological scales. the two scales are highly correlated with each other, but the rating scale provides more information than the ranking scales and can indicate perceived differences between fabrics. a linear relationship between subjective perceptions and measured residual bagging height shows that perception of fabric bagging follows stevens ? power law. residual bagging height contributes up to 94 % of the total variance in the perception of fabric bagging. the rest of the variation may be attributed to anistropic behavior during the bagging process
美觀是消費者日常服裝穿著功能中最重要的指標之一.起拱是一種外衣穿著中引起變化，令人不滿的三維殘余變形.一種主觀評價方法是從一系列起拱織物的照片來理解心理物理學規律，採用優劣排序等級和優劣評判等級兩種方法用於心理評價標度.這兩種等級互相間緊密相關，但評判等級比排序等級包含更多的信息，可以更好地區分出兩種織物間的差異.主觀評價結果與測量得到的殘余起拱高度之間線性相關，表明了織物起拱特性符合斯特藩指數定律.殘余起拱高度對織物起拱特性總方差的貢獻在94 %以上.其它可能是起拱時各向異性因素引起的The main work can be summed up as follows : firstly, we studied the thermal - field properties of vcsels, and analyzed the influences of current spreading, material parameters and operating conditions on the temperature distributions. secondly, we began with the electrode voltage and calculated the equipotential s distributions, compared the distributions of voltages and current densities in different depths of vcsels, and then studied the influences of the oxide - confining region with different position or thickness, and the different sizes of the gain - guided aperture and emitting window on the distributions of the injected current density, carrier concentration and temperature in the active region. thirdly, we realized the coupling of electricity, optical and thermal - fields, worked out the threshold voltage, calculated the distributions of the injected current density, carrier concentration and temperature under different offset voltages, and analyzed the impacts of temperature profile and carrier density on the refractive index, fermi levels and optical - field
