By using the generalized central limit theorem, the heavy-tailed distributions (heavy-tailed Rayleigh distribution for amplitude image and heavy-tailed exponential distribution for intensity image) are obtained from the symmetric stable distributions of real and imaginary parts of echoes. Taking the heavy-tailed Rayleigh distribution as an example, the algebraic tails of heavy-tailed distributions are explained as well as the statistics of sharp peak and heavy tail.

本文使用广义中心极限定理，由雷达回波的实部和虚部的对称稳定分布，得到SAR图像的拖尾分布（幅值图像的拖尾Rayleigh分布以及强度图像的拖尾指数分布），并以拖尾Rayleigh分布为例，讨论了拖尾分布的代数拖尾特征以及尖峰厚尾的统计特性。

For example, we use geometric distribution to describe the life distribution of runs of a species in transect surveys of plant populations and inventory demand distributions. In the theory of reliability, geometric distribution is one of the most important discrete probability distributions because of its loss of memory.

在可靠性理论中，由于几何分布的无记忆性，使得其是离散型寿命分布中最为重要的寿命分布之一，其相当于指数分布在连续型寿命分布中的地位，这正如程侃研究员在文献[5]中所指出的"在离散寿命的情形，几何分布起着连续情形下指数分布所起的作用"一样。

With traditional theory of loss distribution, the goodness of fit of the property loss distribution model depends on the choice of the experience distribution function and parameters.

依赖传统的损失分布理论，财产损失分布模型拟合的优劣往往取决于经验分布函数的选择和参数的确定。

Based on the time history analysis performed on three kinds of high-rise block masonry structures (10-story, 15-story, 18-story structures respectively) and the study on the inertia force distribution of the structures, a new pattern of lateral force distribution, namely parabolic distribution pattern, is presented here.

对3种不同中高层砌块砌体结构(分别为10层、15层和18层砌块砌体结构)进行大量时程分析，对结构的惯性力分布进行研究，提出一种新的适用于中高层砌块砌体结构Pushover分析的侧向力分布模式-抛物线型分布模式，并用该模式分别对3种砌块砌体结构进行Pushover分析。

After that, the article expounds how the social labor value theory overcomes the theoretical hard nuts in the financial accountings:(1) it has solved the issue of conformity between the production domain and accounting domain by holding that the social labor creates the value, which decides that the domains of production and accounting should be extended to cover the tertiary industry;(2) it has solved the issue of the valuation standards in the economic accounting by holding that the theoretical value should be converted into the actual value and that only when the price of production is used as the valuation standards can the financial accounting and economic accounting have a true valuation basis;(3) it has solved the issue of creation and distribution of surplus value and explicitly points out that the power of science and technology determines that the surplus value comes mainly from the materialized labor. Only when we have a clear understanding of this point and have realized that the value of product is created jointly by the materialized labor and the laborer can we straighten out the relationship in the distribution of earning inside the enterprise and understand that the distribution on the basis of contributed capital is a reasonable choice at present.

其次，着重阐述了社会劳动价值论如何解决经济核算中的理论难题：一是解决了生产范围与核算范围的统一问题，认为社会劳动创造价值，决定了生产范围与核算范围都必须扩大到第三产业；二是解决了经济核算的计价标准问题，认为必须从理论价值转化为实际价值，用生产价格作为计价标准，才能使会计核算和经济核算真正具有计价基础；三是解决了剩余价值的创造与分配问题，并明确指出，科技的力量决定了剩余价值主要来自于物化劳动，只有认清这点，承认企业的产品价值是物、活劳动共同创造的，才能真正理顺企业的利益分配关系，才能理解按资分配是现实合理的选择。
