Our other primary insurers delivered their usual fine results last year. These operations, run by Rod Eldred, John Kizer, Tom Nerney, Michael Stearns, Don Towle and Don Wurster had combined premium volume of $579 million, up 40% over 2000. Their float increased 14.5% to $685 million, and they recorded an underwriting profit of $30 million. In aggregate, these companies are one of the finest insurance operations in the country, and their 2002 prospects look excellent.

我们其它初级的保险公司去年的表现依旧出色， Rod，由 John， Don， Tom， Michael 等人带领的各家保险事业，总计贡献了 5.79 亿美元的保费收入，较 2000 年成长了四成，浮存金则增加 14.5%成为 6.85 亿美元，外加 3，000 万美元的承保利益，总的来说，这些公司堪称全美最好的保险公司之一，展望 2002 年他们的前景依然可期。

In aggregate, our smaller insurance operations produced an excellent underwriting profit in 2000 while generating significant float - just as they have done for more than a decade. If these companies were a single and separate operation, people would consider it an outstanding insurer. Because the companies instead reside in an enterprise as large as Berkshire, the world may not appreciate their accomplishments - but I sure do. Last year I thanked Rod Eldred, John Kizer, Don Towle and Don Wurster, and I again do so. In addition, we now also owe thanks to Tom Nerney at U.S. Liability and Michael Stearns, the new head of Cypress.

总的来说，其它规模较小的保险业务在2000年产生了可观的承保利益，同时一如过去十年来持续贡献大量的浮存金，如果把这些公司视为单一独立的企业，那么他们绝对可以称得上是一家经营绩效优异的保险公司，而因为这些事业隐身在Berkshire如此庞大的事业体中，外界无法理解他们的努力与成就，但至少我个人能够深深地体会地，去年我感谢过Rod、John、Don等人，今年则还要再加上美国责任险的Tom以及Cypress的新任主管Michael。

In a smaller but nevertheless important way, our "other primary" insurance operation has also added to Berkshire's intrinsic value. This collection of insurers has delivered a $192 million underwriting profit over the past five years while supplying us with the float shown in the table. In the insurance world, results like this are uncommon, and for their feat we thank Rod Eldred, Brad Kinstler, John Kizer, Don Towle and Don Wurster.

其它规模较小但同等重要的&其它保险&营运一样为伯克希尔增添了许多实质价值，总结过去五年来，这群保险公司为我们贡献了 1.92 亿美元的承保利益，外加下表所显示的浮存金，在保险世界里，能够有这样的成绩实属不易，这都要感谢 Rod， Brad， John， Don 等人。

The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.

W Fryrear等人的计算土壤可蚀部分含量的方程，此方程的自变量包括土壤有机质、碳酸钙、沙粒含量、沙粘比，计算了宁夏主要土壤类型表层的可蚀含量，进而比较它们的可蚀性，并以宁夏土壤分布图为底图用地理信息系统建立了宁夏土壤风蚀数据库，完成了宁夏土壤可蚀性图，评价结果显示宁夏地区主要的土壤类型较容易遭受风蚀；（3）农业经营对土壤风蚀的影响及其评价，在分析宁夏农业土壤遭受风蚀特征的基础上，首先讨论了农业活动对土壤理化性质的干扰，评价主要耕作栽培措施对土壤风蚀的影响，选取粗糙度、表面结皮、可蚀颗粒含量、留茬和有效时间为指标，用打分方法作了评价。

This paper defines a strong security model for multi-recipient signcryption scheme in the random oracle model, which is semantically secure against adaptive chosen-ciphertext insider attack, existentially forgeable chosen-message attack and anonymous chosen-ciphertext insider attack. By analyzing, we point out that Li-Hu-Liu Multi-Recipient Signcryption Scheme is insecure against the adaptive and anonymous chosen-ciphertext insider attacks.

摘要在随机预言模型下定义了一个多接收者签密方案的强安全性模型，该模型满足适应性选择密文内部攻击安全性、选择消息抗存在性伪造和密文匿名安全性；通过分析指出， Li、Hu和Liu等人提出的多接收者签密方案，不具有适应性选择密文内部攻击安全性和密文匿名性，并给出所定义强安全性模型中的攻击方法；随后提出改进方案，该方案在强安全模型中证明是安全的。

Kopin et al, estimate that exogenously administered melatonin disappears from whole mice with a half-life of about 2 min through the first 10 min following injection but that after 40 min the half-life has grown to about 35 min.

Kopin等人，估计外部褪黑素从整个小鼠消失的半衰期在注射后的最初10分钟里，大约为2分钟，但注射后40分钟后半衰期就增长到约35分钟。

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。
