Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

Perhaps it is our ivilized way to moderating,if not preventing,change.

也许，这是我们在以一种文明的方式去缓和改变，如果这不是阻碍改变的话。

If you get a Negative number, and your gut tells you the change is NOT GOOD, decide not to change.

Patients were NEVA normal in 30 vosculogenic ED patients and in 4 were NEVA abnormal 28 non-vasculogenic ED patients.

在非血管组、动脉组、静脉组中有统计学差异的NEVA参数为：每晚勃起次数、勃起持续时间、血容量改变、横截面改变。

An interactive artwork does not so much respond to the viewer as form a double system with him or her in which both the work and the viewer can change (unlike noninteractive art, in regard to which it is thought that only the viewer can change).

一件互动的艺术品并不是将观者本身的互动感受加注於作品中，单纯地以作品回应观者本身的互动感受，因为无论是作品或观者在互动的当时，感受都会改变(非互动艺术作品中，只有观者改变)。

Rather than have an object hierarchy, in an SOA context, we need to be able to change the service provider with minimal or no impact on the consumer?s perception of the service, thus varying the actual implementer of the service description.

在 SOA 环境中，我们需要的不是拥有一个对象层次结构，而是能够改变服务提供者，同时将对使用者的服务感知的影响降到最低程度或者根本没有影响，从而改变服务描述的实际实现者。

Results The incidence of sympathetic ophthalmia was high in youth.The perforating injury was the most common exciting factor(88.00%) More wounds were at corneal limbus(59.32%). The latent period in 2 - 8 weeks was more common(47.89%).
