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.

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.

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。

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.
