中国国电集团公司菏泽发电厂热工，山东摘要：本文论述汽温控制系统组成原理，针对运行中发现的问题，包括一次风母管压力自动设定值设计不合理，导致主汽温度和再热汽温度变化幅度加大，底部注入风量和汽温参数测量不准确，汽温变化迟延大，常规PID满足不了调节要求，采取了相应措施，改用史密斯预测器，更换为ABB定位器，增加底部注入风量等测点防堵装置，并对主汽温自动进行试验和参数优化。

The results show that the alloys are composed of LaNi5 as matrix and LaNi3 as secondary phase. With the increasing Sm substitution for La, the unit cell volume of matrix of the alloys shrinks linearly and both the hydrogen storage capacity and discharge capacity decrease. When the Sm substitution is 0.1, 0.2 and 0.3, the discharge capacity decreases from 380 mA·h/g to 370(362), 355(334) and 329(295) mA·h/g, respectively. However, the rate performance and cycle stability is improved. After 100 cycles, the capacity loss decreases from 20% to 18%(17%), 16%(14%) and 13%(11%).

结果表明：该合金是由LaNi5主相和LaNi3第二相构成；随着Sm取代La量的增加，合金主相单胞体积线性收缩，合金储氢量和放电容量减小，当Sm取代量分别为0.1、 0.2、 0.3时，合金容量由380 mA·h/g分别减小到370(362)、 355(334)、 329(295) mA·h/g，但高倍率放电能力和循环稳定性得到改善， 100次循环后的容量损失率由20%分别降低到18%(17%)、 16%(14%)、 13%(11%)。

Through theoretic reckoning and simulating analyzing, several control strategies for shunt APF were compared and chose ip-iq arithmetic ofthe instantaneous reactive power theory control strategy as the right scheme to produce the instructing current. Based on it, some new control arithmetic was subjoined to suppress the resonance in system and balance the dc side capacitor voltage. Two topologies of main circuit were compared and chose the three-phase voltage-source converter with a split-capacitor as its main circuit structure. The numerical scales of the dc side capacitor and inductance of reactors were calculated. The high-pass filters were designed to eliminate effectively the highfrequency harmonics produced by APF.

The results showed that except pods of main inflorescence, the other characters of the sterile and normal cytoplasms had not significant difference by t test. The correlation coefficients of length of main inflorescence, No. of first time branches and glucosinolates between sterile and normal cytoplasms was at 5 percent significant level, but correlation coefficients of the others was not significant. There were positive effects of male sterile cytoplasm on glucosinolates and weight of 1000 seeds, but different effects on the other characters when combinations were different.
