This paper focuses on how to calculate GPS satellite orbit parameters through IGS data. Choosing a group of appropriate parameters, and the relationship between satellite position in ITRF and these parameters are founded, and these parameters can be estimated using some successive ephemerides. Three different methods are introduced detailedly.

本文以IGS精密星历为基础，深入研究了利用精密星历计算GPS卫星轨道参数的模型与方法，并对三种不同的计算方案进行了比较研究，其目的是寻找一种合适的计算方法，得到能够正确反映一个较长时间段内(如800天)轨道参数随时间变化的规律。

The positioning result of phase and broadcast ephemerides are gained using time-satellite differential model after canceling SA, the precision for 24 hours phase observation data is about 1.1 metre,the precision for 2 hours phase observation data is about 1.3 metre,the precision for 1 hour phase observation data is about 1.6 metre ,the precision for 20 minutes phase observation data is about 2.7 metre.

采用时星差模型得到取消SA后相位和广播星历的定位结果：用24小时的相位观测数据定位精度在1.1米水平；用2小时的观测数据定位精度在1.3米水平；用1小时的观测数据定位精度在1.6米水平；用20分钟的观测数据定位精度在2.7米水平。

The fungicidal activity of methanol extract was higher than that of ethylacetate extract. The bioassay showed that the methanol extracts of strain As fermentation products had certain degree fungicidical activity against Botrytis cinerea, Alternaria longipes, Glomerella cingulata, Curvulavia lunata, Gibberella zeae, Valsa malt under the concentration of 4000μg/mL, the inhibiting ratio against pathogen growth was ranging from 62.9%~85.1%; The results of the inhibition of spore germination indicated that the fermentation products exhibited obvious inhibition rate against Alternaria longipes, the EC50 values was 62.5328μg/mL; The bioassay showed that the methanol extracts of strain As fermentation products had certain degree fungicidical activity against Bacillus cereus , Bacillus subtilis.

其中甲醇提取物的抑菌活性较乙酸乙酯好，在4000μg/mL浓度下对番茄灰霉病菌、烟草赤星病菌、苹果炭疽病菌、玉米弯孢叫斑病菌、小麦赤霉病菌、苹果腐烂病菌6种植物病原真菌均有抑制作用，抑制率在62.9%~85.1%；抑制孢子萌发试验表明：菌丝体甲醇提取物对烟草赤星病菌的毒力较好，其EC50仅为62.5328μg/mL；抑制细菌活性表明菌丝体甲醇提取物对蜡状芽孢杆菌和枯草芽孢杆菌有一定的抑制作用，而对大肠杆菌无明显的抑制作用。
