According to that characteristic and based on the differential equation of the deformed surface of the orthotropic plate, with one principal direction size fixed, changing another principal direction size linearly, maintaining elasticity coefficient the same as in the first principal direction and Poisson ratio equal to the geometric mean of two principal Poisson ratios, the original orthogonal plate is equivalent to an isotropic plate. Results obtained show that the deflections of the equivalent isotropic plate are the same as the deflections of the original orthotropic plate at the corresponding points, the forces of the correspondent points have simple relations.

根据这一特性、从正交各向异性板挠曲面的偏微分方程出发，保持一个主方向尺寸不变，另一主方向的尺寸做线性缩放，保持弹性模量与第一主方向相同，泊松比取2个主方向泊松比的几何平均值，将这类正交各向异性板等效为一块各向同性板；通过分析得到：各向同性板任意点的挠度就是原正交各向异性板对应点的挠度，各对应点内力之间存在简单的比例关系，该文的方法将为工程技术人员提供方便，同时可以更加直观的认识正交各向异性板的受力。

The coarsening direction and final morphology vary with stress axis orientation, the γ′precipitates in [001] orientation coarsen as rod-like structure in the direction of [001] , and those in [110] orientation coarsen in the directions of [100] and [010] to form 〓-like structure, while those in [111] orientation do not exhibit any tendency of directional coarsening, growing isotropically only by capillary-driven style.

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。

The results showed that the air bubble in the coup site mainly suffered from the tensile force vertical to the impacting direction and the air bubble in the contrecoup site mainly suffered from the compressive force in the impacting direction. Since the property of tensile resistance of the brain tissue is inferior to the property of compressive resistance of the brain tissue, the injury is often easier to occur in the contrecoup site than in coup site.

实验结果表明撞击点处的气泡所受到的作用力主要为压力且来自于短轴方向，即撞击方向；对冲点处的气泡所受到的作用力主要为拉力且来自于长轴方向，即撞击方向的垂直方向。

The results show that the methane drainage quantity from the bores perpendicular to face cleat was 1.2 times that of the bores parallel to face cleat in any time and the difference between them becomes more distinct with the drainage time increasing. In the research area, the bores perpendicular to the face cleat was 2.61 times that of the bores parallel to face cleat in maximum drainage quantity and 4.34 times that in drainage effect, and the reasonable time is about 300 days.

Traditionally we continue moving forward with the paper in line with the direction of most of the fibers'packing is called straight grain direction; and a direction perpendicular to the horizontal paper called the grain direction.

习惯上我们把与造纸前进方向一致的大部分纤维排列的方向叫做直丝绺方向；与其垂直的一方向叫做纸张的横丝绺方向。

Self-fluxing Fe-Cr-Ni-B-Si alloy prowders are laser clad on medium carbon steel substrate of dimensions 80×35×10mm〓. The investigation results of this clad layer are: micro-defects, micro-cavity and occluded forin substance, are the micro-cracks and crack resourses in clad layer; crack of coating propagates along the boundary of two kinds of eutectic sutructure; The included angle θ between the cracking direction and laser scanning direction in multitrack overlapping clad is smaller than that in one-track clad because of crack propagating along crystalline growth direction and crystalline direction in overlapping zone being different from it in one-track clad.

在调质态的45〓钢表面，采用预置粉末法进行FeCrNiBSi合金的多道搭接激光熔覆，对其熔覆层进行分析表明：多道搭接激光熔覆层裂纹扩展方向与激光扫描方向间的夹角θ与单道熔覆时相比明显变小，前者θ0°，后者θ角基本都为90°，这主要是因为多道搭接时，搭接区结晶方向发生了变化以及裂纹沿结晶方向扩展所致；激光熔覆层裂纹大多是以覆层与基材交界面的孔洞、熔覆层内不同方向共晶团间的显微缩孔、夹杂物的边界等三种显微缺陷作为裂纹源，并沿低熔点物相形成元素偏析造成弱化膜的共晶团界面扩展延伸。
