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。

Our results suggested that the channel contains two of each subunit and the stoichiometry is apt to 2:2 if hetermeric ASIC channel is a tetramer,while the assembly of ASICs is random,the stoichiometry is not fixed(2:1 and 1:2 coexist)if hetermeric ASIC channel is a trimer.This study provided interesting new data supporting the occurrence of the homomeric and heteromeric assembly of ASICs.

另外，我们还对ASIC异聚体的分子比情况进行了初步的探讨，结果发现如果所形成的ASICs异聚体通道是四聚体，那么每种亚单位有两个，分子比倾向于2∶2；如果是三聚体，则提示ASICs的装配是随意的，分子比是不固定的，2∶1和1∶2这两种情况都存在。

It was found in this investigation that boron exerted considerable influenceon the nucleation and growth of pearlite. In a hypoeutectoid steel, boron delayedthe starting time of pearlite formation at the maximum pearlite formation temp-erature. Boron did not effect the relation of nucleation rate with time butonly increased the incubation period for pearlite nucleation.

从实验结果证明，硼对珠光体的成核及成长是有影响的；在亚共析钢中硼促使珠光体的开始形成时间推迟，增长了珠光体成核的孕育期，但对成核率与时间的关系，在近于A_1温度(700℃)时，略为加速，而在珠光体转变速度最大的温度(650℃)时却没有影响。

The angle might impact material feeding, and hydraulic cylinder was too big, so the structure was incompactly. Against those shortcomings, a new mechanism was designed to actualize the function. The new scheme adopted crank and rocker mechanism for lock and unlock the covering. This mechanism was powered by hydraulic cylinder. The covering would be more stable when the dead point appeared.

论文对生物质压块机盖体开合机构进行改进设计，采用液压缸驱动曲柄摇杆机构实现盖体的开启、闭合，利用机构死点提高盖体闭合时的稳定性，使盖体开合平稳，运动可靠。

The intramolecular hydrogen bonding can extend the ligand planarity and increase the intercalative ability of the complex to DNA. It is concluded that the torsion between the aromatic rings of ligands, due to introduction of the bulky substituent, results in the complexes only to partially or non-classically intercalate into DNA.

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.

From the structural analysis of three praseodymium complexes, we could draw a conclusion that as the dentate arms of carboxyl group on ligands elongating, the coordination numbers of Pr and the coordination modes of ligands increase, and the mean distances between metallic atoms of metallic helices existing in these complexes augment.2. By altering 5-substituting group of isophthalic acid three series of lanthanide complexes 8～19 with 5-methylisophthalic acid and 5-nitroisophthalic acid have been prepared.
