The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

The Additional Guide Star (with star flag 5) is come into use for improving the accuracy and speed of star identification. After the cases analysis of unsuccessful star identification, giving the guide star which always cause false star identification a given star flag(such as 6), which denote that the star is a Redundant Guide Star and can't take part in the star identification processing. Through the introduction of Redundant Guide Star, the accuracy of star identification is improving. The distribution of Additional Guide Stars spread all over the whole sky, even the star sparse area.

在选取导航星的过程中，位置精度阈值的引入，使得高精度的恒星作为导航星，为高精度的卫星姿态反演奠定了基础；辅助导航星的引入，与单一使用Tycho-2星表相比引入了大量的亮星(189颗辅助导航星遍及全天球，其中亮于3等星的恒星占34.4%)，且弥补了部分天区恒星稀疏无法满足星图识别条件的不足，这将十分有利于提高星图识别速度和识别率；冗余导航星的剔除，为进一步提高星图识别率提供了可能。

Test analysis of sparse fall of water pressure In order to examine the water power relation situations of two levels, this ore carried on a experiment of closing the valve in -400m, after turned off the valve one day, the water level rose from -400m to -70m, accumulated water volume 240m3, also two hydraulic pressure rose, it explained that the two water entries had certain water power relation, it also accumulated that the hydrospace are not big.

测试分析稀疏秋天的水压力为了探讨水权关系的情况下两个层次，这个矿进行了一项实验，关闭阀门，在400米后，关掉阀门一天，水位上升至- 400米至70米，累积水量240立方米，还有两个水压上升，它解释说，这两个水作品，也有一定的水权关系，而且还积累了hydrospace并不大。

The spectrum analysis shows that ① Infrasonic waves produced by meteor are mostly very short, lasting one to five minutes;②Periods of the infrasonic waves range mostly from 40 to 408 seconds, and a few waves range from 40 to 480 seconds;③ During 7:21 p.m. to 8:41 p.m. on Nov. 17, the infrasonic waves were much denser. After 8:41 p.m., the waves become more and more sparse, all waves conform to those observed with naked eyes;④ Amplitudes of infrasonic waves from meteor differ significantly from each other (weaker ones below 5 to 10 Pa, medium ones from 10 to 20 Pa, and stronger ones from 20 to 40 Pa). Two of the strongest ones reach 75 Pa and 50 Pa respectively around 7:28 p.m. and 8:07 p.m. on Nov. 17. An explanation of above results is given.

频谱分析结果表明：①各流星产生的次声波大都很短暂，持续时间为1~5min；②流星次声波的周期大都在40~408s；③在1998年11月17日19：21-20：41期间流星次声波仍很密集，20：41后才变得越来越稀疏，恰与肉眼观测结果相符；④流星次声波的振幅彼此相差很大，较弱的在5~10Pa，中等的在10~20Pa，较强的在20~40Pa，最强的两个波在11月17日19：28和20：07前后分别达到75Pa和50Pa。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
