A practical point estimation for the reliable life of a product without life distribution data is established based on a non parameter statistical method. The approximate confidence band of the reliable life of the product can be obtained by trial calculations. This method is simple, widely applicable, and robust.

依据非参数统计方法,给出了在产品的寿命分布未知时,产品的可靠寿命的实用点估计,并用试算方法求得可靠寿命的近似置信区间。这种可靠寿命的点估计与区间估计方法简便易算,应用面广,具有良好的稳健性

Jinshajiang River, which has a drainage area of 485,100 Km 2, average flux of 142.9 billion m 3, and soil conveyance of 247 million t/a, is the largest branch of Changjiang river. It is also the largest soil resource of the Three Gorges reservoir and upper reach of Changjiang River. To research the development and trend of Jinshajiang sediment not only has a relation to Jinshajiang water resource strategy, but also has important meaning to control the silt in Three Gorges reservoir and the Changjiang water...

Jinshajiang River, which has a drainage area of 485,100 Km 2, average flux of 142.9 billion m 3, and soil conveyance of 247 million t/a, is the largest branch of Changjiang river. It is also the largest soil resource of the Three Gorges reservoir and upper reach of Changjiang River. To research the development and trend of Jinshajiang sediment not only has a relation to Jinshajiang water resource strategy, but also has important meaning to control the silt in Three Gorges reservoir and the Changjiang water resource development. The paper statistically analyses the flux and sediment conveyance of the Pingshan station, which is the primary hydrological station in the Jinshajiang River Drainage Area. Through several non-parameter statistical methods such as Spearman order correlativity check, Kendell order correlativity check, and linear regression check, the paper concludes that the sediment evolvement trend of Pingshan station is not distinct.

金沙江集水面积 4 8.5 1万Km2 ,多年平均径流量 142 9亿m3 ,输沙量 2 .4 7亿t/a ,与长江上游的其它支流相比 ,是流域面积最大 ,产水、产沙最多的河流 ,是三峡水库和长江上游的最大沙源。研究金沙江泥沙演变过程和趋势 ,不仅关系到金沙江水资源开发战略 ,而且对控制三峡水库泥沙淤积及开发长江水资源亦具有重要意义。对金沙江流域主要水文控制站———屏山站的流量、输沙量进行了统计分析 ,运用非参数统计的Spearman秩次相关检验、Kendell秩次相关检验、线性回归检验等方法 ,对屏山站的水沙演变趋势进行了分析检验 ,得出了水沙演变无明显趋势的结论。

This paper statistically analyses the runoff and sediment transport of the major stations in the upper reaches of Yangtze River. Compared with the annual runoff and sediment transport before 1990, there were three major changes of annual sediment transport in the term of 1991-2002: the Yichang station decreased about 1.3×10~8t; the Pingshan station at the Jinsha River increased about 0.35×10~8t, and the percentage (compared with Yichang station) also increased from 51.8% to 71.9%; and the Beibei station increased...

This paper statistically analyses the runoff and sediment transport of the major stations in the upper reaches of Yangtze River. Compared with the annual runoff and sediment transport before 1990, there were three major changes of annual sediment transport in the term of 1991-2002: the Yichang station decreased about 1.3×10~8t; the Pingshan station at the Jinsha River increased about 0.35×10~8t, and the percentage (compared with Yichang station) also increased from 51.8% to 71.9%; and the Beibei station increased about 0.985×10~8t, and the percentage also decreased from 25.7% to 9.1%. Through several non-parameter statistical methods such as the moving average check, the Spearman order correlativity check and the linear regression check, the paper concludes that the trend of runoff evolvement at the Pingshan station is not distinct, and nor is that of the sediment transport increased; but trends of the runoff and sediment transport decreased are very distinct; the trend of runoff evolvement at the Yichang station is not distinct, and the trend of sediment transport increased is distinct. The major factors correlated with the runoff and sediment transport changes such as the rainfall, water-and-soil conservation measures, reservoir trap and artificial inducements of soil etc. are also introduced.

对长江上游主要控制站水沙量进行了统计分析。近期长江上游水沙变化特点主要表现为:与1990年前相比,1991-2002年宜昌站年均减少沙量约1 3亿t;金沙江屏山站年均增加沙量约0 35亿t,其占宜昌站的百分数由51 8%增加到71 9%;嘉陵江北碚站年均减少沙量约0 985亿t,占宜昌站的百分数由25 7%减小至9 1%。采用滑动平均法以及Spearman秩次相关检验和线性回归检验等方法,对屏山、北碚和宜昌等3站水沙变化趋势进行了分析,分析结果表明:宜昌站径流量无趋势性变化,但输沙量有减小趋势;北碚站水沙减小趋势均较为明显;屏山站径流量无趋势变化,但输沙量有一定的增大趋势。另外还对影响长江上游水沙变化的降水量、水土保持措施、水库拦沙以及人类活动增沙等主要因素进行了分析。
