Focusing on some disadvantages in standard BP algorithm, such as low convergence rate, easily falling into local minimum point and weak global search capability, Genetic algorithm is used to optimal the connection weight of BP Algorithm in this paper, and construct a GA-BP algorithm of evolutionary neural network, and the algorithm is applied to the control of BLDCM speed adjusting system.

针对标准BP算法存在全局搜索能力弱和易陷入局部极小点等缺点，本文将遗传算法与BP神经网络相结合，构造了一种新的进化神经网络GA-BP算法，并将该算法应用于无刷直流电机调速系统的控制，仿真结果表明，与传统的PI控制系统相比，该算法得出的电机控制曲线几乎无超调，与基于BP算法的速度控制系统相比较，具有收敛速度快、不易陷入局部极小的优点。

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

Because divergence timing of the West Clade from the East Clade of S. japonica complex was estimated to be Aquitanian of Miocene (23 Ma), during which the mountains and plateau of Southwest China were formatted, the divergence of the West Clade from the East Clade of s. japonica complex was presumably correlated closely with the uplifting of mountains and plateau of Southwest China. The multiple variations of the West Clade of S.

西部集群居群间具有更大的遗传分化值和更大的遗传分化值变动范围，提示西部物理环境的复杂性导致更多的小区域隔离，小的基因流和更大的绝对成种速率，这与西部的物理环境的复杂性是相协调的，并且可能是造成西部山地高原地区生物多样性异常丰富的微观过程和机制。
