     As the gradual maturity of the biased estimation of the linear regression model without additional linear equation restrictions, a great deal of statistical problems such as in the experiment design, hypothesis test, the models of variance analysis and the covariance analysis and so on, which show in practice the investigative significances and the applied values of the restricted linear regression, need to be regressed with several additional linear restrictions.
     不带线性等式约束的线性模型的有偏估计已经发展得相对成熟,但在大量的统计问题中,如实验设计、假设检验及其方差分析模型和协方差分析模型,往往需要在某些约束条件下对模型进行回归分析,这使得带线性等式约束的回归分析具有很重要的研究意义和应用价值。

    In this article the statistic problem of the parameters of physical properties of rock and mineral is discussed for geophysical prospecting interpretation. Practical material shows that it mainly corresponds to normal distribution and logarithmic normal distribution. The reason is analysed why the magnetic susceptibility mainly tallies with norml distribution and the theory grounds which produce other distributions are also studied. The. choice of statistical estimates is discussed, in author's opinion the expectation μof the parameters of physical properties of rock and mineral specimen should be used in theory calculation and interpretation of all geophysical prospecting methods applied the principle of linear superposition. The optimum estimates of μ. are discussed in different distribution and size of sample. Both the calculative formula concerned and nomography are introduced.

    A statistic T is said to be a contraction of a statistic S provided T is a measurable function of S. This conception and its various extensions are applicable to the class of sub-o-fields[1] and it is quite useful when minimal sufficient statis-tics(and subfields) and some other statistical problems are to be investigated. A few theorems concerning the relationship between two concepts of contraction are proved with all definitions surveyed.

    若统计量T可表为统计量S的可测函数,则称T比S精或S比T粗.这个概念及其种种推广,也适用于子σ-域.这个概念在研究极小充分统计量(和极小充分子σ-域)及某些其他统计问题时有用.本文考察了种种关于精粗概念的定义,证明了若干有关的定理.

    The First National Symposium on Catastrophe Economics since the founding of the People's Republic of China was held in Beijing from May 15 to 18, 1987, under the joint auspices of the Research Society of China Land Economics, the Popular Science Commission of the Chinese Seismological Society, the Insurance Society of China and the China Water Conservancy Research Society. This paper gives a brief account of thesymposium; outlines the main problems discussed during the symposium,including: the importance of the science of catastrophe economics; the objects and tasks of catastrophe-economics research; economic issues in disaster forecast, prediction and preparedness; disaster relief and compensation for economic losses; and economic statistics of disasters. It also presents some constructive suggestions put forward by the participating representatives.
