The research result shows that the best fuel delivery advance angle of diesel engine used has been changed; with the first cylinder as the standard, the deviation of the fuel delivery advance angle between the first cylinder and other cylinder surpasses allowed range; the smoke emission and fuel consumption can be decreased and delivering fuel to each cylinder at the right time can be assured, through the selection and adaptation of fuel delivery advance angle .

研究结果表明：使用后柴油机的最佳供油提前角发生了变化；以第一缸为准，其它缸与第一缸之间的供油提前角偏差超出了允许的范围；实行供油提前角的调配可使各缸在正确的时刻供油，减少排放，降低油耗。

The speed also affects combustion noise through variation of advance angle.

推迟供油提前角可以显著降低噪声。2、燃烧系统多参数分析2.1、喷孔数目在喷油压力不变时，减少喷油孔数量，可使促进燃油雾化，使着火延迟期缩短，因而有助于降低压力升高比，汽缸压力频谱线也相应降低，尤其是中、高频成分降的更多些。

By properly using turbocharger,increasing the efficiency of air charge, improving the machining process for the liner and reducing the advance angle of fuel feeding etc, the particles and NOx of improved 4102BZQ diesel engine were reduced so that it can meet EuroⅠemission standard.The develoPMent of Model 4102BZQ improved diesel engine allows the 4-cylinder engine of DCD to meet the emission legislation forced by our country, and extends the life-time of DCD engines, which makes a contribution to the develoPMent of DCD economy and protection of environment.

The results are as follows.(1) Long train electrical stimulation at the dMNF facilitated myoelectric activities of genioglossus and phrenic muscle.(2) Short train electrical stimulation of dMNF, when delivered in the inspiratory phase, caused prolongation of myoelectric activities of genioglossus and phrenic muscle; but when delivered in the expiratory phase, myoelectric activities of genioglossus and phrenic muscle were shortened.(3) Long train electrical stimulation at the vMNF inhibited myoelectric activities of genioglossus and phrenic muscle.(4) Short train electrical stimulation of vMNF caused shortening of myoelectric activities of genioglossus and phrenic muscle, when delivered in the inspiratory phase, but a prolongation when delivered in the expiratory phase.(5) The effects of microinjection of glutamate to dMNF and vMNF were similar to those of electrical stimulation.

结果如下：(1)长串电脉冲刺激dMNF引起颏舌肌和膈肌肌电活动明显增强；(2)短串电脉冲刺激dMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动延长，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动提前终止；(3)长串电脉冲刺激vMNF使颏舌肌和膈肌肌电活动明显被抑制；(4)短串电脉冲刺激vMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动提前终止，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动延长；(5)在dMNF和vMNF分别微量注射谷氨酸钠，其效应与电刺激结果基本一致。

Effects on reproductive performance: The normal delivery of group B,C and D were 80%、93.33%、93.33%,respectively,were improved by a certain extent comparing with the control group; The mean birth weight of calves were not significantly different between the trial and control groups.But numerical datas shown that supplementing Zn-Met in dietary had the tendency to increase the birth weight of calves; Supplementing Zn-Met in dietary can make dairy cows express empathema earlier,and significantly(P.05).Among the trial groups,the advanced extent of the group C was comparatively large(5.8d);The oestrous cycles were all in normal range and not significantly different; The levels of serum PRL of group B,C and D were significantly(P.05) 1.46 ng/ml、3.08 ng/ml、3.45 ng/ml higher than the group A.
