扇形的

A new method of folding segmental filter paper is introduced.

介绍了扇形滤纸的一种新的折叠方法，并与常用的折叠方法进行了比较。

Through the analysis and research,it was found out that the gate position of the runner system should be selected properly.

经分析认为，模具的浇注系统要选择好浇口位置，浇口形式采用扇形浇口，其尺寸应与产品的有关尺寸相吻合，以保证后续工序的切断加工。

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.

基于线性矩阵不等式分别导出了具有扇形角约束和范数有界约束的两类非线性关联不确定系统的线性无记忆状态反馈控制律设计方法，该方法不要求系统的两输入项对系统完全可控。

There they spread out like foragers on a picket line, each alone or in small groups probing a carefully chosen, narrow sector.

在那里他们如同远征队员那样按警戒线散开，独自或者三两成组的搜索他们面前经过仔细选择的狭窄的扇形区域。

Whereas this method is compared with the usual method-folded of segmental filter paper?

介绍了扇形滤纸的一种新的折叠方法，并与常用的折叠方法进行了比较。

In the first part,we give the inner radius of univalency for fan-shaped domains and for quadrilateral domains with vertexes on a circumference and sides forming the sequence abba .

在第一部分中，我们给出了扇形和四边为abba形式的圆内接四边形的单叶性内径，并给出了长方形区域单叶性内径的下界估计。

Fig. 1. The plan and side view of the flow of a molten polymer liquid in gas-assisted injection molding where a pipe is connected vertically to line A to a fan-shaped cavity with a vertex angle of 180度 formed by two parallel plates and gas is injected at the point above where two cavities are connected.

图。 1。该计划和侧面的熔融聚合物液体流动的角度在气体辅助注塑成型在管道连接垂直线A到一个扇形腔一顶点由两个平行板和气体形成的夹角为180度在上述点注入其中两个腔相连。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
