Firstly, the paper introduced the working principle and device of the two-pass grate-rotary kiln and had an analysis method of mechanics of the tyre. We have put forward the finite element analysis of the contact stress of the tyre-roller based on the whole construction mode of shell-kiln liner-large gear-tyre-roller of the rotary kiln and obtained the strength and distributing rule of the tyre's contact stress. The research shows that within one week the contact stress mainly lies in two leading peak value and catastrophe which appear at the contact zone of the tyre and supporting roller. Then we regarded the tyre's stress as the test of unknown plane stress of principal stress. Utilizing mature and modern testing technology, we raised the testing principle and scheme of tyre stress and then had a on-the-spot test of the stress. Comparing the analysis result of the test with the one calculated from the finite element analysis, it proofed the rationality of finite element analysis method of integral modeling and the correctness of the contact stress result of the tyre and roller. Finally, for two-pass of similar rotary kilns, using the ANSYS APDL re-development technology, carried on the re-development about the overall finite element analytic method of thecontact stress of tyre-roller.

首先，本文介绍了2档回转窑的工作原理和装置，对滚圈的力学行为进行了分析，提出了基于筒体-滚圈-托轮的回转窑整体建模的有限元分析法，来对滚圈-托轮的接触应力进行有限元分析与计算，得到了滚圈接触应力的大小和分布规律，并求得滚圈外中内圈节点的主应力；其次，把滚圈的受力看成是主应力未知的平面应力的测试，利用现代测试技术，提出了滚圈主应力测试的原理和方案，并对滚圈的主应力进行了现场测试，现场测试分析结果与有限元分析计算出的主应力相比较，证明了整体法建模的有限元分析方法的合理性和滚圈-托轮接触应力结果的正确性；最后，利用ANSYS的APDL的二次开发技术，针对2档同类回转窑，就滚圈-托轮接触应力的整体有限元分析法进行了二次开发。

Villa and colleagues randomized 277 young women (mean age, 20.2 1.7 years) to receive quadrivalent HPV vaccine, and 275 women (mean age, 20.0 1.7 years) were randomized to receive one of two placebo preparations at day 1, month 2, and month 6. Participants had regular gynecological examinations, cervicovaginal sampling for HPV DNA, testing for serum antibodies to HPV, and Papanicolaou testing for 36 months.

Villa博士指出，在已开发国家中，因为子宫颈癌筛检的彻底实施，子宫颈癌已经转变为癌前病变的管理，亦即HPV感染的控制；在这些国家中，为了管理所筛检出来的异状，医疗、心理及经济层面的成本付出皆会增加，而这些都可藉由通用的HPV疫苗接种而降低，同时也可更进一步降低子宫颈癌的发生率。
