We deal with the biharmonic equation and proved that under our assumptions, the week solution of the natural boundary value problem strongly converges (in H~2) to that of the first boundary value problem.
为克服这一困难,我们用具自然边界条件的边值问题(在二阶椭圆型方程情形为第三边值问题)去逼近相应的第一边值问题,并以重调和方程为例,证明了在一定条件下,其具自然边界条件的边值问题的弱解在H~2的意义下强收敛到相应的第一边值问题的弱解。

The impacts of material spatial variability were usually not considered in traditional slope stability analyses. However, most geotechnical materials are usually not uniform inside a slope. Thus, traditional ways of analyses were not very reasonable. On the other hand, most geological explorations used vertical borings. Horizontal and inclined borings were seldom performed unless required by the client.
摘要 传统边坡数值稳定性分析时,大多没有考虑到材料空间变异性之影响性,材料无论在理论上或是在实际边坡上很少边坡为均质材料,因此传统的边坡分析是种较为不合理的现象,而地质钻探时都是以垂直钻探为主,除试验需要外,极少以水平或倾销钻探作为设计之基础,这也与现地所需有关系,导致空间变异性资料难以取得必需以现地资料加上文献中提及的尺度变动作为分析依据。

日常生产情况表明,不论是手工裱贴或机械自动裱贴,都难免会出现裱贴不准现象,为防止裱贴后的非制卡和会员卡制作面的规矩纸边出现凸出现象,一般在制卡和会员卡制作时就要根据产品的特点,将制卡和会员卡制作半成品的侧规和前规纸边加放3~6mm不等的修边余量,这样裱贴时,将非制卡和会员卡制作面的规矩纸边适当往内缩若干毫米进行裱贴,可有效地防止非制卡和会员卡制作面的规矩纸边出现凸出现象,保证产品模切的准确。

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.
