放射性的

Based on the natural gamma log curve s of acid tuff and clay rocks of acid volcanic events,the author here queries the arguments that radioactive intensity of sedimentary strata will grow with the increasing argillaceous materials and that the natural gamma value and the empirical equation can be used to calculate contents of argillaceous materials.

The heavy elements in the theory of spontaneous metamorphosis immediate sensation around the world ;(4) is proposed to estimate the Earth's radiation age;(5) from the charge-mass ratio α which is derived helium ions;(6) from the scattering of α Bighorn recognized atomic mass concentrated in a radius of 10-12 meters in the nuclear, on positively charged core surrounded by negatively charged electrons;(7) with natural α-particles from the nitrogen nuclei in the outgoing protons, this is the first time human beings to change the chemical elements of artificial nuclear reactions;(8) predicted that heavy hydrogen and neutron sub-existence .

这一重元素自发蜕变理论立即轰动全世界；（4）提出用放射性估算地球年龄；（5）从α的荷质比得出它是氦离子；（6）从α大角散射认识到原子质量集中在半径为10－12米的核上，核带正电，周围是带负电的电子；（7）用天然α粒子从氮原子核中打出质子，这是人类第一次实现改变化学元素的人工核反应；（8）预言重氢子和中子存在。

A geological time scale based mainly on both biostratigraphy and radiometric dating created stratigraphic refulgence, but at the cost of lowered accuracy and preciseness and weakened function of serving the human society.

以生物地层学为基础并与放射性同位素定年技术相结合建立的、以百万年为计时单位的地质年代表既创造了地层学的辉煌，也在一定程度上降低了地质学对精确数字定年的不懈追求和为人类社会服务的功能。

The average activity concentrations of gross-beta was 4.30×10^(-1)Bq/L.

对矿山造成的塌陷坑水体的开发利用和环境生态系统的恢复后就注意放射性水平的变化。

The nuclear reactions in the initial study, the discovery of the neutron in 1932 and in 1934 the synthesis of artificial radionuclides is a representative The results of .40 before and after the age of nuclear physics has entered a phase of great development .1939, the Hahn and Strassman found that the phenomenon of nuclear fission in 1942, Fermi established the first fission chain reactor, which is human with nuclear energy start.

在初期的核反应研究中，1932年中子的发现和1934年人工放射性核素的合成是具有代表性的成果。40年代前后，核物理进入一个大发展阶段。1939年，哈恩和斯特拉斯曼发现核裂变现象，1942年，费米建立了第一个链式裂变反应堆，这是人类掌握核能源的开端。

The inventive method and device enable to decontaminate the inside surface of a hollow body or a component arranged inside the hollow body (1) which can be a cleaning vessel.

本发明的方法和装置可以消除一个空心体的内表面或一个放在一个可以是一个清洗槽的空心体(1)内的部件的放射性污染。

When blanket is designed, some necessary data, including tritium breeding ratio, irradiation damage ratio, intensity of activation radiation, magnet and thickness of shield, can be get through neutronics calculation. All of that must base on heat load and neutron power flux of first wall and divertor plate. So, the preparative calculation is prformed for that.

在设计包层时，需要进行中子学计算得到氚增殖率、辐射损伤率、活化放射性强度、磁体及其屏蔽厚度的计算、核加热产生率和冷却系统设计和安排的必要数据，而这一切都必须先知道第一壁和偏滤器靶板的中子壁负荷和热负荷；为此作了必要的先行准备计算工作。

Back in the fifties Tom Eisner, a colleague of mine, and I did I believe the first experiments tracing radio-active labelled sugar-water through colonies of ants.

答：在50年代我的同事Tom Eisner跟我做了我认为是最早的使用放射性标记的糖水探查蚁群的试验。

With the development in nucleus technology application,radiation source amount and eradiation accident both increased.

随着核技术应用领域的逐步扩展、放射源数量的增多及辐射事故突发频率的提高，2003年《中华人民共和国放射性污染防治法》发布并实施，该法明确了环境保护行政主管部门对放射源实行统一监督管理的职能。

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。
