查询词典 type region

For a general system, our Lyapunov function-based method can give a low conservative estimation for the region of attraction, moreover, a much more large region of attraction by using Matlab/LMI optimization.

对一般系统，我们用基于Lyapunov函数的方法给出保守性尽量低的吸引域的估计算法，再配合基于Matlab线性矩阵不等式优化方法去综合控制器，以便得到尽量大的吸引域。

Further, the stability region estimation problem for mismatched uncertain plants′VSC systems is studied and solved, and a more extensive sufficient stability region estimation result is gotten. By analyzing the result, the relation between the control bounds and the system robustness is shown.

在控制受限的情况下，改进和完善了文献[58，59，130]提出的确定性对象或匹配不确定性对象变结构控制系统的稳定域估计方法，并进一步研究了失配不确定性对象变结构控制系统的稳定域估计问题，取得了更广泛更全面的充分性稳定域估计结果，从中分析得出了控制受限界与控制系统鲁棒性的关系。

Adopting the network of radial basis function ormended BP network,the forecasting network model of stock on estimation region can beestablished.The stock of each pixel in estimation region can be calculated through simulationapproach,the total stock of compartment or sub-compartment can be obtained by way of theintegration to all pixels.

通过径向基网络或改进的BP网络建立估测区域蓄积预报网络模型，借助仿真方式计算估测区域每个像元的蓄积，对全部像元积分可得到林班或小班的总蓄积。

In DAPI banding pattern, the dark region is generally thought to be euchromatin rich and the bright region is heterochromatin rich. It just provided the experimental foundation for the above deduction.

在DAPI带型中，暗区一般被认为是常染色质较丰富的区域，而亮区为异染色质较丰富的区域，这正好为上述的推论提供了实验依据。

Since then, the gene localization has developed from simply being described as at the euchromatin region and heterochromatin region to more complicated nuclear localization. Therefore, the gene regulation attracted more attention now.

因此基因在细胞核内的定位就由原来简单认为的异染色质区和常染色质区发展得更为深入了，基因在细胞核内的定位以及位置的变化与基因表达调控之间的关系也越来越受到重视。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.

我们发现，在用Euler方法求解二次优化问题的等价动力系统的方程时，由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域，因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

These years the region develop very fast base on the linkage and concert. The thesis makes the Yangtze Delta as the sample of producer logistics, with the method from model to normal and from the advanced point to the extendedness. With analyzing the status in quo and the features of the region, we can acquire the important use for reference and guidance.

本文以长江三角洲地区生产性物流服务业发展作为分析样本，本着从典型到一般、从先进示范到普及推广，分析其发展的现状与特征，其生产性物流服务的供给现状、需求现状，明确长江三角洲地区生产性物流服务业发展特征，总结长江三角洲地区生产性物流服务的发展经验，这将对中国其他地区生产性服务业发展具有重要的借鉴作用和指导意义。

Just as the relationship between the fluctuation of foreign trade and economic growth, the influence of the change of net trade volume among regions on regional economy is very complex: in the short term , the increase of surplus and the decrease of deficit are beneficial to increase the economic power of the region from the angle 0f external demand; in the long term, the increase of trade deficit in short period of time may increase the development strength of regional economy from the angle of strengthening the supply capacity of the region.

同时，与对国外贸易波动和经济增长的关系异常复杂一样，区域间净贸易量变化对区域经济的影响也十分复杂：从短期看，顺差扩大与逆差减小有利于从外部需求的角度去增强本区域的经济增长动力；从长期看，则短期的贸易逆差扩大有可能从增强本区域供给能力的角度去增强区域经济的发展后劲。

At first, the extremal control of the system was got, then the reachable region of the time reversed system and the controllable region of the system were given.

首先求取系统极端控制，进而给出时间反转系统的可达区域和系统的可控区域。

Basic ecological information of a region should include fauna and flora of that region.

一个地区的生态环境的信息必须包括其动物和植物区系。

I was up all night because I was in pain, she said.

我整夜，因为我在疼痛，她说。
