High density stacking faults are induced into Al-Co-Ni decagonal quasicrystal by using high temperature deformation. It is found that their fault planes are perpendicular to the ten-fold axis and their displacement vectors R are lying in the fault planes and parallel to a two-fold axis A2D.

通过高温形变的手段在Al-Co-Ni十次准晶中引入了高密度的层错，并发现这些层错的层错面与十次轴垂直，层错的滑移矢量R在层错面内并与二次轴A2D平行。

It is clearly shown that the Al-Ni-Rh decagonal quasicrystal with 1.6 nm periodicity contains a kind of atom columnar cluster with about 1.6 nm periodicity as the most fundamental structural building block.

主要的研究结果可以总结如下：1利用高分辨电子显微技术在Al_(75)Ni_(15)Rh_(10)合金中发现了1.6 nm周期的十次准晶，报道了这种准晶在二次轴方向及在十次轴方向的高分辨结构，阐述了其周期及其准周期的排列方式。

Since the ellipse minor axis always goes through the center of our square this is something we can use to help us draw it.

椭圆次轴总经过中心区域，这对我们画图十分有用。

When you observe the minor and major axes of the ellipse we see that the minor axis goes through the center of the square while the major axis does not.

这时你会观察到椭圆的次轴经过其中心区域，而主轴则没有。

Understanding the mechanics of drawing ellipses is not difficult, mastering the drawing of ellipses is. An ellipse has two axes we need to know about, the minor axis and the major axis.

掌握画椭圆的规则并不困难，对于椭圆我们首先要了解其两个轴，主轴和次轴。

According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall. The other is Z or ring shaped a-c 90°domain boundary along {010} direction, and the displacement vector 〓 runs along 〓 direction.

根据界面相对于样品中(100)观测面取向的不同，90°畴可分为两类：一类为薄透镜片状或环状的a-a90°畴，其界面平行于{110}，多数不带电，由消光规律可确定其位移矢量平行于畴界面与自发极化所在平面的交迹，即，〓方向，而从包含畴界的选区电子衍射图可知，这种不带电的90°畴界两侧存在微小的取向差，其界面两侧的结晶学关系为以界面法线为二次轴的旋转关系；另一类为Z状或环状的a-c90°畴，其界面平行于[010]或[001]，相应的位移矢量为〓方向。

At each penton, a hole (φ=20〓) can be seen connecting the inside and the outside of the capsid, and there is a hole (φ=12〓) at each hexton and the center of 2-fold axis, so there are 132 holes in total at the surface of CSBV.

应用冷冻电镜技术和计算机三维结构重构的方法，我们测定了CSBV核衣壳的三维结构，分辩率为25 〓，病毒的核衣壳是按T=1（P=3）的对称结构排列二十面体，病毒表面比较光滑，有12个五邻体、60个六邻体的结构，每个五邻体的中央有孔洞，六邻体的中央也有孔洞，另外在2次轴的位置上也有孔洞，这样病毒共有132个孔洞，五邻体的孔洞的直径为20 〓，而六邻体和二次轴的孔洞的直径月为12 〓。

Above all, we are supposed to introduce prejudication system, and follow the civil law as the principal axis, the system of jurisprudence for the axis of relations between the two legal systems coexist, so that they can get a total of habitat in China, thus to form the legal system with Chinese characteristics.

综上所述，我们应该引进判例制度，要遵循以大陆法系为主轴，以判例制度为次轴的两种法系并存关系，使它们能在中国得到共栖，从而形成具有中国特色的法律制度。

In the highly undercooled melt, a roughening transition from the lateral to continuous growth mode was found.

在过冷 Al72Ni12Co16十面体准晶合金中发现沿十次轴方向的连续生长和沿二次轴方向的侧向生长的不同生长机制。

The computationresults show that for a organ-pipe nozzle with a given configuration size, the nondimensional axial velocity attenuates slower with the increase in stand-distance, and the nondimensional axial velocity attenuation pattern remains the same, and the nondimensional axial velocity along the jet centerline attenuates slower with the increase in distance between the nozzleexit and the impinging plate.

计算结果还表明：对给定结构尺寸的风琴管喷嘴，随着喷距的增加，沿径向的无因次轴向速度衰减变慢、沿径向无因次轴向速度衰减规律不随喷速的变化而变化；无因次轴心速度的衰减规律随着喷嘴出口到井底间距离的增大，射流轴心速度衰减变慢，但其变化幅度不大；在固定靶距情况下，无因次轴心速度衰减规律不随喷速的变化而变化。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
