The phase-shifts caused by reflection and transmission of the beam splitter were investigated by its eigen-martix.The general relationship between these phase-shifts of two splitted beams used for coherent combining was obtained,then the fact that when constructive interference occurs in one side of the beam splitter and the destructive interference has to occur in the other side was explained in the point of phase-shift.

利用分束器的特征矩阵研究了分束时产生的反射与透射相移，得到了两束相干光经过分束器分束后进行相干叠加时相移满足的普适关系，从相移的角度解释了分束器一侧发生相长干涉时另一侧必然发生相消干涉这一现象。

The results show that the microscopical pore structure of the three dimensional orthogonal woven carbon fabric structure perform is composed of body-centered cubes which arranged periodically at spaces. The net structure and shape of the pores of perform are determined by the size and proration of the fasciculus diameter, which are key factors influencing the gaseous permeability and final density of composites. Once the proration of the fasciculus diameters of different directions is determined, the trend of diversification of the permeability followed by pore rate during CVI process and the density of composites are stated, and the permeability increases with the increase of the fasciculus diameter.

研究结果表明：三维正交结构炭纤维预制体的宏观孔隙结构在空间上可以看成是由呈周期性排列的体心立方"晶胞"构成； X ， Y 和 Z 3个方向纤维束直径大小及比例关系决定三维正交结构炭纤维预制体宏观孔隙网络的结构和形状，也是决定反应气体在孔隙中的比渗透率和复合材料最终致密度的重要因素；当 X ， Y 和 Z 3个方向纤维束直径的比例关系一定时，不同预制体在CVI增密过程中比渗透率随孔隙率变化的趋势相同；复合材料的最终致密度一定；比渗透率随纤维束直径增大而略有增大。

The more classically beautifulAdrienne is swimming in the typical park-strolling attire of the time—adoublebreasted tunic layered over a full, floor-length skirt, blousedup over a belt obscured by a bunch of extra fabric, some kind of ahigh-collared shirt tightly buttoned around her neck, and one of thoseinfamous fin de si cle hats that looked like a platter of pastries.

看上去更具传统美态的Adrienne依然包裹在当时流行的公园漫步风格的服饰中――上着一件对襟的束腰外衣，下穿一条长及地面的裙子，束着一条隐藏在串串织物下的腰带，还让某件高领衬衣紧紧环扣在她的脖子周围；她还戴了一顶具有19世纪末风格的帽子――那种帽子名声不太好，看上去简直就像一个装满馅饼皮的大盘子。

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.
