matlab sps is used to build a simulink model of single-machine infinite-bus system, and based on the simulink model, simulation on effect of pss suppressing small disturbances low frequency oscillation is carried on, and some methods of improving power system transient stability are simulated, including avr and pss, short circuit cleared rapidly, fault current limiter and single-phase auto reclose. the study unifies the simulink model to realize matlab and vb seamless integration using the activex technology, and demonstrated the matlab simulation result with the vb contact surface. this method of matlab and vb integration can make up the matlab contact surface unfriendly flaw and offers a reference for the design for cai of power system analysis course.

运用matlab电力系统仿真模块集sps构建了单机—无穷大系统simulink模型，对电力系统稳定器抑制电力系统小扰动低频振荡的效果进行了仿真；对提高电力系统大扰动功角稳定性的措施，如自动电压调节器及电力系统稳定器、快速切除故障、故障限流器、自动重合闸等手段的使用效果进行了仿真验证；并结合单机—无穷大系统的simulink模型运用activex 技术实现sps与vb的无缝集成，将sps的仿真结果用vb界面显示，较好地弥补了matlab用户界面不友善的缺陷，为《电力系统分析》课程进行cai设计提供了思路。

The experimental evidence has shown that the polygonal Co particles are the final form. We found that Co formed nanocrystallites of 2-5 nm in diameter in the surface coating layer of the Mg_2SiO_4 crystalline stems and then aggregate into large clusters. These clusters further grow and recrystallize into polygonal single crystals. Instead of the single crystals, it is the polycrystalline clusters that played the most important role in Mg_2SiO_4 growth.c.

b。实验中观察到的现象表明多面体的Co颗粒并不是一开始就形成的，而是首先在Mg_2SiO_4的枝干表面以2-5nm的纳米晶体聚集成较大的团簇，这些团簇再继续生长并在最后重结晶为多面体的形状。

Correlation analyses on the contents and ratios of endogenous hormones with selfing fertilities showed that selfing fertility was not determined only by one single hormone level, but partially affected by the joint action or balance of several hormones in Nongken58S original and untransformed regenerant controls under long-day. Our results did not support different already proposed hypotheses on one single hormone action in fertility expression of PSGMS rice.

1通过对因受环境低温影响而在长日条件下不育性部分逆转的原始材料和组培再生后代材料的自交结实率与内源激素水平及比值相关性分析表明，农垦58S育性转换并非取决于某种单一激素水平的改变，而可能与多种激素的共同作用和平衡关系有关，从而说明&众说纷纭&的单一激素作用的假说难以成立。

A non-singular single integral mathematical model is adopted to calculate the external intermittent and alternative longitudinal magnetic field acquired by single axisymmetrical and cylindrical hollow coil t which is coaxial to electrode and excitated by a revisable pulsed current of square wave t in austenitic stainless steel GTA welding.

针对奥氏体不锈钢外加纵向磁场的气体保护钨极电弧焊接时，与电极同轴的单个轴对称空心圆柱线圈在双向脉冲矩形励磁电流作用下产生的间歇交变纵向磁场，采用无暇点单积分磁场的数学模型，对＊TAW焊接外加间歇交变纵向磁场进行了数值计算，该方法具有模型简单、计算速度快和精度高等优点并讨论了该间隙交变纵向磁场的分布、磁场的均匀性及其纵向分量与径向分量的比率等规律及其对焊接行为的影响，认为横磁分量将削弱GTAW外加纵向磁场的有利作用，影响磁控电弧的焊接质量

Jorge Posada hit a leadoff single, reaching third when centerfielder Torii Hunter let it get past him, and scored on Silva's wild pitch. Matsui doubled and scored on a single by Abreu, who was safe when shortstop Jason Bartlett failed to hold the throw on an attempted steal. One out later, Cano was hit by a pitch by Juan Rincon. After the runners moved up on Damon's comebacker, Cabrera singled to drive in both. He took second on the throw to the plate and scored the fifth run of the inning on the second of Jeter's three hits.

Jorge Posada率先击出安打，并且因为中外野手Torii Hunter 让球滚到身后而登上三垒，再趁Silva的暴投得分，松井击出二垒安打后靠著Abreu的一垒安打得分，Abreu则因游击手Jason Bartlett无法接住传来的球而盗上二垒，在一人出局之后，Cano被Juan Rincon的触身球打上一垒，两位跑者靠著Damon打回给投手的滚地球推进之后，Cabrera击出一垒安打把他们都送了回来，并趁球传回本垒时上到二垒，最后靠Jeter三支安打中的第二支得到该局的第五分。

Accumulation experiments were performed with:(1) Scenedesmus quadricanda as single food;(2)a 50:50 mixture of Scenedesmus quadricanda and Microcystis aeruginosa based on carbon concentration; and (3) Microcystis aeruginosa as single food. MCs inside Bellamya aeruginosa were tested by ELISA, and a curve for the dynamic variation of MCs is obtained.
