A STATISTICAL PROCEDURE TO EVALUATE CLEAN-UP STANDARDS

The object of this paper is to develop a suitable statistical procedure to evaluate clean-up standards athazardous waste sites.Under the assumptions that contaminant masses at a site follow a gammadistribution and that the data from the pre-remediation baseline sample as well as from the interim orfinal sample taken after a certain period of operation are both distributed as gamma with the same shapeparameter but different scale parameters,we derive a uniformly most powerful unbiased test of thehypothesis that a specified percentage of contaminant mass has been reduced.A large-sampleapproximation of the exact test procedure and a comparison with the likelihood ratio test are provided.     

LIKELIHOOD TECHNIQUES FOR INTERLABORATORY CALIBRATION IN THE NATIONAL STREAM SURVEY

Techniques for testing for and estimating relative bias between two laboratories are developed andapplied to a survey of the chemistry of streams in the United States.The design of the quality assuranceprogram allows estimation of linear corrections for bias as well as testing of the hypothesis of linearity,Designs of this type are useful,but improvements are suggested.     

意大利Ivrea区高温剪切带中斜长石的局部不平衡

意大利Ｉｖｒｅａ区变辉长岩和角闪岩中２０条表面上相似的角闪岩相韧性剪切带内，斜长石的显微构造和化学分析表明，这些斜长石在Ａｎ和Ｂａ含量上有很大的差别。斜长石在ｐ－Ｔ低于岩中的条件时发生变形，并伴随出现４种不同的显微构造和不同的化学成分：（１）相对没有变形的碎斑；（２）碎斑边上的动力生结晶颗粒和亚颗粒；（３）横切碎斑的裂隙中的充填物；（４）剪切带基质中细粒重结晶颗粒。

封闭温度原理及在大地构造研究中的应用

<正> 同位素地质年代学的研究表明,对某些地质体,用不同的年代学方法测得的年龄常常不一致。如钾氩法和裂变径迹法所测得的结果经常比铷锶法所测得的结果年轻,而用钾氩法对云母所测得的结果又比对角闪石所测得的结果年轻。某些地质学家曾一度怀疑     

秦岭商丹缝合带变质砂岩地球化学特征及构造环境探讨

秦岭商丹变质砂岩分布于一般认为的华北板块与扬子板块的结合带。常量、微量、稀土元素地球化学特征和岩石学、区域地质构造的综合分析表明其形成构造环境像是岛弧-活动大陆边缘型,沉积物质主要来源于北秦岭构造带的秦岭杂岩。与M.R.Bhatia等的地球化学判别参数相比,这套岩石的Ti、Zr、NB、Co、La、Nd含量和K_2O/Na_2O值偏高,主要是受沉积源岩成分的直接影响所致。因而,地化参数不是判别构造背景的唯一标志,应根据区域地质背景与源岩性质而加以修正。
