In this paper, problems of trend test in clinical experiment are studied mainly by the statistical inference method under order restriction. The ori- gins of order restricted statistical inference are usually dated back to the early 1950s. At about the same time, a number of researchers started working inde- pendently on similar problems. The field developed rapidly during the 1960s and early 1970s and formed the more perfect theory of estimation and test- ing.

分别对取自尾矿坝区的4种尾矿料进行颗粒分析试验、原状土与重塑土渗透试验、尾矿浆水渗透试验，分析了颗粒级配、孔隙比及时间对尾矿料渗透系数的影响。

Based on the project of high-embankment widening of highway, the water content and degree of compaction of foundation soil, filling and improved soil by lime were determined by means of indoor physicomechanical test. The centrifugal modeling tests were used to simulate increasing degree of compaction and improve soil by lime for coordinating deformation between new and old high-embankment widening.
