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 -
According to the fluctuating property of wind, on the stochastic vibration finite element theory, some calculation formulas of the response, including the along - wind response and the across - wind response, are obtained, the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time. by using the stochastic vibration module of the general finite element program, the paper analyses the performance of the wind resistance more deeply and fully, discussing the influence on the double - tower structure from the diversification of the different component. the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration, so is the effect of several parameters on dynamic displacement, acceleration and wind - induced vibration coefficient
從結構風振的基本理論出發，通過對脈動風功率譜的分析，推導了結構風振響應（順、橫風向）的計算公式，同時提出了雙塔結構的扭轉振動和動力風荷載計算的思想，在結合通用有限元程序的隨機振動模塊的情況下，對雙塔結構的抗風性能作了深入、全面研究，探討了雙塔結構構件截面的變化對其抗風性能的影響，同時探討了順風向風速譜的選取、風速、參與計算的振型數、風與結構耦合作用是否考慮等因素對分析結果的影響，比較了規范風振系數的計算與隨機演算法結構的異同，並討論了原因，得出一些有意義的結論。 -
The purpose of this article is trying to further verify the inference in demonstration angle : 1. it is testified according to insurance fund application retrospect analogy, the published of insurance law in 1995, it makes way one entire accounting reorganization and variance from mandatory institution to out of order investment of the hypothesis of criterion behaving insurance fund application, country execute policy of further encouragement and unlock to fund application. but because of unlikeness of investment financial environment in china at present, insurance fund application exist a lot aspects of urgency reformation not only in investment, but also management mode
對我國保險資金運用的回顧和分析表明， 1995年《保險法》的頒布，對以往保險公司的無序投資進行了一次全面整頓與強制性制度變遷，並且近年來，在規范保險資金運用行為的前提下，國家對保險資金運用實行進一步鼓勵與放開的政策。但是，由於中國目前投資金融環境不完善，保險資金運用無論從投資范圍還是管理模式，都存在著一些問題，急需改革。 -
The concept of complete convergence was introduced by p. l. hsu and robbins [ 11 ] in 1947 : for arbitrary > 0 and i. i. d random variables with mean zero and variance 1, we have this conclusion strengthened classical strong law of large numbers in the direction of borel - cantelli lemma
完全收斂性的概念是許寶祿和robbins [ 11 ]於1947年提出：對于均值為0 ，方差為1的獨立同分佈的隨機變量序列和任意0 ，我們有這個結論沿著borel - cantelli引理的方向加強了古典的強大數律。 -

It was used widely in chinese country, it not only is an important choice during the reformation of collective enterprises, but also is regarded as an important realization form of public ownership. it accelerates the development of productivity. with the development of economy and the environment variance, there are many problems with the organizations format that was created by chinese peasants, the theories, the policies and the law about rscs are so lagged that they hold back the development of it
農村股份合作制是我國農民繼家庭聯產承包責任制后的又一偉大創造，它極大地促進了生產力的發展，在我國農村地區得到了廣泛的應用；二十多年來，它不僅成為農村集體企業改革和新組建企業的一種重要的選擇，而且也成為公有制的一種重要的實現形式。
