放射性的

However, unlike the simple exponential that describes radioactivity, which has only one variable, a stretched exponential describes a process controlled by several independent factors.

不过，与只有一个变量的放射性简单指数不同的是，延伸型指数函数描述的是被几个独立因素控制的过程。

The United States since February 28, 1954 at the Bikini Atoll in the Marshall Islands on a power of about 15 million tons of TNT equivalent of the hydrogen bomb tests, resulting in serious radioactive contamination caused fishermen were killed and led to the development of the "clean" hydrogen bomb (fission share of the small hydrogen bomb) of concern and working on the so-called "pure fusion weapons."

美国由于1954年2月28日在马绍尔群岛的比基尼环礁上进行的一次威力约为1500万吨梯恩梯当量的氢弹试验，造成严重的放射性沾染导致渔民死亡，引起了对研制"干净"氢弹的关注并致力于研究所谓"纯聚变武器"。

The method needs several parameters, such as average fission yields of fission products, correction for reaction, decay correction for radlioactive fission products in reactor, average fission energies of fissionable nuclides and so on.

它需要若干参数，如裂变产物的平均裂变产额，反应的修正量，放射性裂变产物的堆内衰变修正量，可裂变核素的平均裂变能量等。

With respect to storage and disposal facilities for radio-active and other hazardous wastes, it is crucial to understand how contaminants move through the geosphere and how long-term performance of disposal facilities can be affected by geological and climatic changes over time.

至于放射性和其他有害废物的储存和处理设施，很关键的一条是必须了解污染物如何在陆界中移动，以及这些处理设施的性能会随着时间的推移，受到地质和气候的影响。

This paper focuses on the application of the methods developed in ISAM to the Borehole Safety Assessment which is based on the Borehole Disposal Concept of Nuclear Energy Company of South African.The hypothetical geosphere and biosphere characteristics for the safety assessment are derived from the radioactive waste disposal site in northwestern China.

本文采用ISAM中开发的评价方法，参考南非原子能公司的钻孔设计概念，并根据我国西北放射性废物处置场的岩石圈和生物圈特性假定场址，对废放射源钻孔处置安全评价方法进行了研究，为我国废源钻孔处置的安全性提供依据。

While the uranyl ion and the hydronium ion tend to dissolve in water, the effect of ancient underground water leads to the redistribution and movement of the elements of uranium and kalium, the ratio of thorium to uranium and kalium are changed.

为了需求古地下水的运移规律及对寻找矿床的作用，利用放射性元素钍稳定性的特点，建立了钍归一化判断的数学模型。

High measure precision: High precision and low operation error can meet needs of various levels of operator, identical measurement results can be gained in spite of different practical experiment of operator.

测量精度高：不但测量精度高，且个人操作误差小，不同的测量人员，不管有无经验均可获得相同的测量值。●使用范围广泛：可测大型、重型工件某个部位的尺寸，也可适用于高温、放射性等恶劣环境条件下的测量。

The results of the intercomparison of its radioactivity measurementsare good, and applications of the standard radioactive solution of ~(241)Am aresatisfactory.

这些都表明本文提供的方法是正确的，由此得到的~(241)Am标准溶液是准确可靠和稳定的。完全符合放射性计量标准的要求。

Among the substances in third-hand smoke are hydrogen cyanide, used in chemical weapons; butane, which is used in lighter fluid; toluene, found in paint thinners; arsenic; lead; carbon monoxide; and even polonium-210, the highly radioactive carcinogen that was used to murder former Russian spy Alexander V.

三手烟中的物资包括用于制造化学武器的氢氰化物，轻质石油的丁烷，涂料稀释剂中的甲苯，砷，铅，一氧化碳，甚至还有谋杀了前苏联间谍亚历山大利维尼柯的极具放射性致癌物资钋210，三手烟中11种组成物质都是高致癌物资。

What is even more incredible, is that one of the authors of the fictional letter, Lippmann, was the one to read to French Academy of Sciences the first paper written by Madame Curie on her discoveries of radioactivity.

更难以置信的是这封作伪证的信的作者之一，李普曼，竟是法国科学院阅读过居里夫人发现放射性第一篇论文的读者之一。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
