By analyzing the mechanics relation between the sprocket wheel and the pallets of the pallet draught device in a sintering machine , the non - arching mechanics model of the pallets was established and the force control method for the non - arching sintering machine was put forward 摘要通过分析带式烧结机台车执行牵引装置的星轮和台车的力学关系，建立了台车无叠肩起拱的力学模型，提出了无叠肩起拱带式烧结机的力控制方法。
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 美观是消费者日常服装穿着功能中最重要的指标之一.起拱是一种外衣穿着中引起变化,令人不满的三维残余变形.一种主观评价方法是从一系列起拱织物的照片来理解心理物理学规律,采用优劣排序等级和优劣评判等级两种方法用于心理评价标度.这两种等级互相间紧密相关,但评判等级比排序等级包含更多的信息,可以更好地区分出两种织物间的差异.主观评价结果与测量得到的残余起拱高度之间线性相关,表明了织物起拱特性符合斯特藩指数定律.残余起拱高度对织物起拱特性总方差的贡献在94 %以上.其它可能是起拱时各向异性因素引起的
This machine has great feeding ability , easy to be regulated , can be fed with fixed quantity under control of time delay relay ; it is divided into one - way feeding and bidirectional feeding in terms of feeding direction , suspending type and seating type in terms of installation ; in order to assure precision of feeding , roller encapsulation is equipped to increase frictional coefficient between adhesive belt and rollers ; the rectangle discharging mouth has large dimension which can prevent humping up materials ; this machine has close structure , reliable application and can be easily repaired because it has many similar parts with belt type conveyor 该机给料能力大，调节给料量方便，又可在时间继电器的控制下定量给料按给料方向该机可分为单项给料和双向给料，按安装方式又分为吊挂式和座式为了保证给料的精度，主动滚筒包胶，以增加胶带与主动滚筒的摩擦系数料仓矩形卸料口的尺寸大，物料不易起拱该机结构紧凑，使用可靠，它与带式输送机有许多通用部件，故维修方便。
Therefore , the precise estimate for deflection upwards of prestressed concrete bridge , from which searching for the reasonable design and construction method , is very important for practical projects . the theme of this paper is to solve the problem about how to determine the deflection upwards precisely and to seek the control methods of over - deformation 因此，对预应力混凝土桥梁的起拱度进行较精确的预估，利用计算的起拱值来寻求更为合理的设计和施工控制方法，从而对工程实践具有较强的指导意义。
