In this paper, the research object is the XM18 spherical generator, in order to improve the dynamic behavior of the machine tool, the following aspects have been studied in this thesis: Firstly, based on the elasticity theory and finite element analysis theory, the finite element models of the lathe bed, dovetail, dovetail shelf, headstock, fanlike plank and millhead shelf, which were the main parts of the spherical generator, were built up using ANSYS9.0. And based on the modal analysis theory and FEM technology, the free modal and the constrained modal analysis of the main parts were studied. Accordance to the analytical results, put forword methods to optimize the key parts.

本课题以XM18球面铣磨机为研究对象，为了提高其动态特性，本文主要从以下几个方面进行研究：首先，根据弹性力学理论和有限元分析的基本理论，利用ANSYS9.0软件建立了铣磨机的主要零部件床身、燕尾、燕尾座、主轴箱、扇形板和磨头座的有限元模型，利用有限元法对主要零部件进行了自由模态和约束模态分析，并根据分析结果对关键部件提出了改进方案。

In the river sediment model with a movable bed , there are two key problems which are how to think about interaction of water and sediment and how to proceed the large distorted roughening to meet resistance similarity.

在河流动床泥沙模型中，如何考虑水沙之间的相互作用，以及在模型动床上如何进行大变态加糙，以满足河流阻力相似，一直是难以解决的两个关键问题。

It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.

认为要控制好PRD弱凝胶钻开液的性能，流型调节剂PF-VIS的加量是关键；PRD弱凝胶钻开液的粘度随着剪切速率的降低而急剧上升，显示了其优良的井壁携砂带砂性能；PRD弱凝胶钻开液体系具有较好的高温稳定性；PRD弱凝胶钻开液体系在低剪切速率的高粘度，大大高于传统聚合物钻井液，有利于在大斜度井携带岩屑以及防止岩屑床的形成。

Human brain bridging veins may be the key point of brain vein blood outflow volume because of existing of "outflow cuff segment": ICP increased, outflow resistance increased, outflow volume reduced, then caused the aggravatation of vein blood deposition in vein bed. Such a sequent procedure formed an infernal circle: ICP increase-vein outflow reduce-vein blood deposition-ICP increase all the better.

该部分研究结果发现，由于流出口狭部的存在，人脑桥静脉是脑静脉血液流出被动调节机制的关键环节，颅内压增高，流出阻力增加，流出量减少，进而又加重了血液在静脉血管床的淤积，形成颅内压增高-静脉流出量减少-静脉血淤积-颅内压进一步增高的恶性循环。
