扇形

For the compressible materials, in order to satisfy the higher-order compatibility equation of the rate of deformation in the centered fan sector, which is a quite difficult problem unresolved in the previous studies, a particular term must be added to the expansions of the stress components in the regular logarithmic power series adopted by many researchers before. A higher-order near tip field with tangential velocity jump ahead of the crack tip is derived first, of which the dominant terms are the solution widely accepted.

对可压缩材料，本文首先采用非规则的对数幂级数渐近展开方法，克服了过去研究中存在的中心扇形区变形率协调方程的高次渐近式不能被满足的困难，并得到了一个切向速度在裂尖前方存在间断的高阶渐近解，该解的主项就是目前被广泛接受的关于可压缩材料的尖端场解。

There is a single class, order, genus and species, the maidenhair tree or ginkgo from China, known only in cultivation.

具扇形，二叉叶脉的叶片，此即为其保留有裸子植物特征的唯一性状。银杏为雌雄异株。

Fan charts mapping efficiency and function remain to be some increase is mainly the application code!

绘制扇形统计图效率和功能仍有待提高主要是一些代码的应用！

Pathology and ultrastructure detection revealed cell necrosis and collapse, sever nuclear damage was observed in the death cells. The early characteristics of necrosis such as margination of heterochromatin was also found in some tumor cells. Besides, well differentiated tumor cells, degenerative tumor cells and some lymphocytes were seen.

直形针给药组肿瘤组织早期表现为大片的组织坏死，晚期表现为存活区域的增加，坏死区域与存活区域界限分明，两者间多有移行带；弧形针分段扇形注药者早期、晚期组织均表现为大片坏死，肿瘤间质内可见淋巴细胞浸润和纤维结缔组织增生；各时间段的检测标本中都可见一定数量的凋亡细胞，但比例远远小于坏死的肿瘤细胞。

As an application, we present the coupling of FEM and natural boundary element.

作为应用，我们也研究了无限扇形区域的有限元与自然边界元耦合法。

The nominator of Equation 1 is multiplied by the G M factor representing the relative antenna gain of the main beam compared to the sector antenna gain.

等式1的提出者将其再乘以 GM 因子后来表示；较之扇形天线增益而言的，主要波束的相对天线增益。

Linear memoryless state-feedback control law is derived for two classes of uncertain nonlinear interconnection systems with sector restriction or norm-bounded restriction based on Linear Matrix Inequality. This method doesn't require that two input terms are absolutely controllable for nonlinear delay systems.
