C.Triple Eccentric Metal-seated Butterfly Valve adopts a double-eccentric and a Sideling Cone surface.

第三、斜锥面金属密封蝶阀设计采用了一个双偏心和一个斜锥面密封结构，实现蝶板在开启瞬间，密封面随即分离，关闭接触时，密封圈挤压后，自身微量变形，实现密封

Detailed siress analysis was carried out for a section of the pipeline including an eccentric reducer on which long cracks appeared twice.

进而对曾两次出现长裂纹的偏心异径管管段进行细部应力分析。

To control the base design of power machine using numeric,taking the blower as an example,the key problem affected by power machine load,base and subgrade-the off-center value between centroid of control load and poid of foundation subface was analyzed.The relationship of calculating maximum amplitude of machine foundation and permitting amplitude was discussed.

以风机为例，对动力机器荷载、基础和地基共同作用的关键问题—控制荷载重心与基础底面形心的偏心值进行分析，并对机器基础最大振幅的求解与允许振幅的关系进行了论述，以便对动力机器基础的设计能从数值上加以控制。

Corneal topograph guided enhancement was safe and effecitive after PRK for regression 、central island and eccentric ablation.

角膜地形图引导下的个体化切削对矫正PRK术后出现的切削偏心、中央岛及屈光回退安全、有效。

Methods 11 cases loss UCVA or had optical aberration were undergone enhancement guided by corneal topograph , which included regression 5 cases、central island 3 cases、eccentric ablation 3 cases . Visual acuity and visual complication were followed for 6 months.

对11眼（11例）PRK术后出现视力不良者(其中偏心切削5例，角膜中央岛3例，屈光回退3例)在角膜地形图引导下进行个体化准分子激光切削，术后随访6月，观察视力和视觉症状。

The result of this study was show: Yonex Ultimum RD Ti-35 in tension of 50 pounds racket Eccentric impact zoom at 12 ofI1ock had the shortest the settling time and lowest vibration response.

研究结果发现：一、Yonex牌Ultimum RD Ti-35张力50磅网球拍在偏心撞击振动响应时问方面，撞击在12点钟位置较优於撞击在其他各点上之时问。

Combining with the structure and the technological requirement of the aluminum alloy support , took the support bottom suface big plane as the parting surface, selected the eccentric side pouring system, selected the slanting slide core-pulling mechainsm because of the die casting part with two undeep holes.

结合铝合金支座的结构和工艺要求，以支座底面的大平面作为分型面，选用偏心侧浇道浇注系统。考虑到铸件的侧壁有两通孔、且不深，选用斜滑块抽芯机构。

4Have done a great deal of research work, while on the stiffened ones, Wanget al. [5, 6, 7] have also done a series of research work. But up to now, tothe author's best knowledge, there have been no papers reported in the openliterature on the stability analysis of the laminated composite shells of revo-lution, both unstiffened and stiffened, by the finite element method.

在SABA族元素[1]的基础上，把复合材料各向异性的弹性性质考虑进去，把纵向筋条处理成为空间梁，计入梁偏心的影响，由梁的基本弹性和几何刚度矩阵出发，经过一系列变换，推导出与SABA元素相协调的新的弹性和几何刚度矩阵，从而较为精确地得到了复合材料叠层及加筋的稳定性分析结果。

Maxium valum of axial torque were measured by static eccntric loading test on the instrumented spines at last; Another 8 fresh frozen human cadaveric spinal speciments were used in this biomechanical test, the testing constructs used were:〓vertebrectomy and 〓 discectomy, bone-graft with anterior Kaneda device, mesh-cage interbody fusion device, mesh-cage with Kaneda fixation, mesh-cage with posterior pedicle screw system TSRH.

利用腰椎三维运动分析系统进行生物力学稳定性测试及静态偏心加压极限扭转载荷测试。2）取8个新鲜冷藏的人尸脊柱标本，分别行〓椎体全切，〓和〓椎间盘全切，制作损伤失稳模型，依次实施四种重建术式：髂骨块植入加前路Kaneda钢板固定，钛网椎间融合器植入，钛网和前路Kaneda联合应用，钛网和后路TSRH椎弓根系统联合应用。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
