But time will not allow me come back to the past time. It let me miss my direction on the coordinate axis of life. The original love ask me go ahead in the direction of straight .In that case.I will not meet the 0degree ice .And straight forward this road .I can see the raising sun.And will find out the beautiful view which others will never meet .If I turn my direction into the opposite one .I will just see the mirage, I trusted her. From childish time to grow up. I accepted many regards from different region and different persons.I shows a big smile all the time . I learnt thanks. Thanks for god let me live in such beautiful world. Thanks for the person who care of me; I leant sympathy .

但是时间不允许我再回到原点，它让我在人生的坐标上失去的方向，原本的爱一直指导我向正坐标走，它告诉我那样我不会遇到零度坚冰，一直走下去会看到初升的太阳，会看到很多别人的看不到的美景，它告诉我如果真得往恨的方向走，我看到的只是海市蜃楼，所以我听它的，从小到大，我接收到了来自同或者不同的地域的人的爱护，我一直咧开一张嘴笑着，我开始学会了感谢，感谢上仓让我生在这样一个世界，感谢我身边每一个人对我的关怀；我开始学会同情，同情一些孤儿老人和备受战争残害的人…。。

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。

Because of the paper mesorectum grain direction and cross grain direction of expansion rate, stiffness, and so a series of physical properties of significantly different, is the difference between paper grain direction means a lot, here are a few simple and convenient way.

由于纸张在直丝绺方向与横丝绺方向的伸缩率、挺度等一系列物理性能的显著不同，区别纸张丝绺方向的办法很多，下面介绍几种简便易行的方法。

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。

There is also a belief, from paper, paper direct comparison of the grain direction, easy-to-stiffness and transportation; blowing and horizontal grain direction of the paper is not enough stiffness to the two ends of the easy-to-source or curls, purging and transportation, so you should move the paper direction and straight grain feeding direction parallel to cards and membership cards.

还有一种说法认为，从输纸来看，纸张直丝绺方向比较硬挺，便于吹松和输送；而横丝绺方向纸张挺度不够，两头易于向下或者向上卷曲，影响吹松与输送，所以应将纸张直丝绺方向与输纸方向平行来制卡和会员卡制作。

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。
