查询词典 joints

It is in his limbs and joints also it is curiously in the joints of his hips and wrists

它也显现在四肢和关节上，奇怪的是在他的大腿和手腕的关节上

The influence of with or without longitudinal joint, with or without initial opening, with or without filling in the joints and different friction factor in the joint face and so on are studied on the seismic response of Fengman Dam. Thus the conclusions for gravity dams with longitudinal joints is drawn.

对于丰满重力坝，本文考虑了有、无纵缝，纵缝有、无宽度，纵缝有、无填充物及缝面的不同摩擦系数等情况，进行了静动组合的地震反应分析，对存在纵缝的重力坝的抗震特性得出了一系列规律性的认识。

The modal tests of PCB and PCB assembly (free boundary condition and fixed boundary condition) were carried out. The equivalent elastic modulus and damping parameters of PCB can be gained, and the fixed boundary condition of finite element model was also determined. These will help to the following work. Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted. It was found in our drop tests that the root cause of lead-free solder joints under drop impact was the combined effect of mechanical shock and PCB bending vibration.

针对JEDEC标准试件的局限性，提出了设计便于统计学研究焊点可靠性的试验试件的构想，利用有限元模态分析方法确定并验证了用圆形PCB组件替代JEDEC标准试件的可行性；通过一系列模态试验和有限元模态分析，确定了圆形PCB组件的相关试验参数，这不仅为跌落碰撞下PCB组件有限元模拟确定了较为合理准确的有限元模型，而且为正确地评价跌落碰撞下PCB组件的可靠性问题奠定了基础。

Through the study of joints of different sizes in granite mass, it is known that joints not only control lumpiness of granite materials but also provide a good structural environment for weathering of the rock, causing the continuous development of weathering and the deeping of decoloration.

查明节理不仅直接控制石材的块度、荒料率，而且为石材的风化变色作用提供良好的构造环境，促使花岗石风化变色作用的加深及其效果的扩大化。

Thirdly, with FEM analysis software ANSYS, this paper has fulfilled appropriate pavement FEM models. Selecting right loading locations and parameters, this paper has simulated contact behaviors of limited dimension cement concrete pavement with joints afterwards. The mechanics response results and load transfer ability results of matchboard joints have obtained and the effect of reinforcing steel bars has gained too.

3利用大型通用有限元分析软件ANSYS，建立合理的路面模型，选择合适的荷载位置和荷载参数，模拟有限尺寸设接缝水泥混凝土路面的接触行为，得到水泥混凝土路面的力学性能和接缝传荷能力等结果，并考虑了有无钢筋对路面性能的影响。

However, for multistory and multibay frames in which there are a large number of members and joints, and which will, in general, involve translation as well as rotation of these joints, the effort required to solve the correspondingly large number of simultaneous equations is prohibitive.

然而，对于多层和框架的MultiBay，其中有一个成员和大量关节，并会在一般情况下，涉及翻译，以及这些关节旋转，这种努力要解决相应的方程组的大量过高。

A plane joint model was built in this thesis. By using it, not only M-θ curve of joints but also open of segment joints, stretch of connected bolts and contact stress distribution on joint faces can be obtained.

为此，本文建立了平面型纵缝接头的力学模型，根据该模型除能得到衬砌二维计算所需的接头M-θ曲线外，还能分析接头面的受力状态并得到接缝的张开值、螺栓受力。

Facet joints oriented parallel to the sagittal plane provide substantial resistance to axial rotation but minimal resistance to shearing forces, whereas joints oriented more in a coronal plane tend to protect against flexion and shearing forces but provide minimal protection against rotation fig.

小关节朝向趋于矢状位可以限制脊柱的轴向旋转但是减少了对剪应力的限制。而趋于水平的小关节可以更好的保护屈曲和剪切下的应力，但对旋转的抵抗力降低（图3）。

In more recent studies by Masharawi et al.46 andPunjabi et al.,47 the investigators found that the upper lumbar facet joints (T12–L2) were oriented closer to the midsagittal plane of the vertebral body (mean range,26°–34°), whereas the lower facet joints tended to be oriented away from that plane (40°–56°).

近期， Masharawi 和 Punjabi 等人的研究发现，上位小关节（ T12–L2）的趋向更接近椎体的正中矢状面（平均角度26°–34°），而低位腰椎小关节的趋向远离正中矢状面(40°–56°)。

Ligaments were very important to provide stability of knee joints, but some dancing motions take shearing force to knee joints and caused ligaments overstretch.

同时，闭锁运动链的运动型态也促进了踝关节及足部的本体知觉。膝关节的韧带在支持膝盖的稳定度上扮演了非常重要的角色，但是有些舞蹈动作会在膝关节形成一个剪力进而造成了韧带的过度牵张。

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。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
