In terms of the customer - driven parameter descriptions , parameter mapping and the establishment of encoding regulation on module properties , this paper develops a quantified arithmetic description model that transforms product customization problem into an issue of module assembling optimization 通过客户驱动参数描述、参数映射、模块特性参数编码规则的建立，得出定量描述的数学模型，从而使产品定制问题转变为模块的组合优化问题。
In the task space , the attitude space of the robot end - effector is parameterized by rodrigues parameters , and an output feedback controller without the generalized velocity is designed for controlling the position and attitude of the end - effector of a rigid robot 利用机器人控制系统固有的无源性，在作业空间中，采用rodrigues参数描述末端执行器的姿态，设计了用于机器人末端执行器位姿控制的输出反馈控制律，消除了控制器中的广义速度。
Tokyo , 1988 , 7 : 7 - 18 . 14 maeda s . compensatory articulation during speech : evidence from the analysis of vocal tract shapes using an articulatory model . hardcastle , marchal speech production and speech modeling , dordrecht : kluwer academic publishers , 1990 , pp . 131 - 149 本文根据生理学实验，心理学实验和计算模型模拟的结果提出语音在大脑的语音生产系统和语音感知系统中的参数描述，并试图证实语音至少是元音的感知过程是一个简单的拓扑映射。
On the basis of two items of survey about the indigenous hotels in chong qing , simply descript the works already done and the difference of the indigenous hotels by the history of hotel , the management of hotel and the applying of ci , and so on . meanwhile , it puts forwards an idea that the indigenous hotels in chong qing could show their characteristic image through combining their own development with culture about hotel and culture in chong qing 本文通过对重庆本土酒店的两项调查，以酒店历史、酒店的经营现状、酒店的ci导入情况等为参数描述了本土酒店在形象建设方面己开展的工作和不足之处以及本土酒店彼此之间的差异；同时在形象战略的核心部分? ?形象定位中提出，本土酒店应结合自身的历史、酒店文化及重庆文化等塑造自己鲜明的具有个性化的形象。
The main results and academic contributions of the dissertation can be summarized as following : 1 ) for the difficulty to obtain the accurate analytical solution of the stress constraints around 3d cracks , detailed 3d fe analyses have been conducted to study the out - of - plane constraint factor tz around a straight through - thickness crack , a quarter - elliptical corner crack and a semi - elliptical crack embedded in an isotropic elastic plate subjected to uniform remote tension loading . the distributions of tz are minutely studied in the forward section of the cracks . strong 3d zones ( tz > 0 ) along the crack front were investigated despite the far field stress - free boundary conditions 全文主要研究内容和学术贡献如下: 1 .针对一般三维裂纹端部场应力约束准确解析的困难,对均匀拉伸载荷作用下各向同性弹性板中穿透厚度中心直裂纹、半椭圆表面裂纹和1 / 4椭圆角裂纹进行了大量详细的全场应力三维有限元分析,首次全面分析了非穿透裂纹端部场三维影响区范围,给出了不同形状三维裂纹前沿离面应力约束因子tz的数值解,并结合k场平面解给出了非穿透裂纹端部应力场k - tz双参数描述。
