In this paper, we report our structure observation and U-Pb zircon ages of the two types of Triassic granites, and use these data to place chronological constraints on the tectonic evolution of the western Kunlun orogenic belt. The gneissic garnet-bearing granite was crystallized at 241 Ma, whereas the horblende-bearing granite emplaced at 228 Ma.

In terms of structural characteristics and geochemistry of the granites in conjunction with previous studies, we interpret that the garnet-bearing gneissic granite was formed during the collision between the Tianshuihai terrane and the Southern Kunlun terrane following the closure of a branch of the paleo-Tethyan ocean along the Mazha-Kangxiwa suture zone, the block hornblende-bearing granite was formed during post-orogenic extension. On the other hand, the granites of ca.

根据两个岩体的构造特征，结合前人的研究及地球化学特征，表明含石榴子石片麻状花岗岩形成于同碰撞造山时期，是甜水海地体与西昆仑南带晚古生代岛弧沿麻扎-康西瓦缝合带碰撞峰期的产物，代表了沿麻扎-康西瓦分布的古特提斯洋一个分支的闭合，而228 Ma块状含角闪石花岗岩形成于碰撞造山后的伸展背景。220～190 Ma持续发育的花岗岩是南昆仑地体拼合到北昆仑地体之后在其南部形成的新的深成岩浆弧带。

Background : Individuals with hemiparesis frequently shift most of their body weight to uninvolved side, showing a obviously asymmetry of standing posture and weight bearing pattern. Postural asymmetry places the individual with hemiparesis at a greater risk for falls. Asymmetry weight bearing contributes to gait abnormalities.

研究背景：半边麻痹的中风患者时常会把身体的重量放在好边的脚上，让好脚去承载身体大部分的重量，因而产生明显不对称的站立姿势和两脚不对称的重量承载比例，姿势的不对称会致使患者跌倒的危险性更大，重量承载的不对称会致使患者走路时有不正常的步态。

In the model of ball bearing, three nonlinear factors were considered, such as the clearance of bearing, nonlinear Hertzian contract force between balls and races, and the varying compliance vibration because of periodical variety of contact position between balls and races.
