A formula for non-dimensional synthetic electronegativity was obtained by multiple regression analysis. The correlation coefficient (R=0.9844) and test of significance Sig.

采用回归分析法，对周期表中除零族、氢及放射性元素之外的77种元素的Pauling电负性X(下标 P进行回归分析，得到了一个无量纲的综合性的电负性计算公式，相关系数(R=0.9844)和回归方程F检验的显著性水平Sig。

Conventional radiochemical methods such as alpha spectrometry, neutron activation analysis, liquid scintillation system, fission track and gamma spectrometry for the quantitative determination of neptunium and plutonium often require complicated and time-consuming sample preparation and separation procedures.

研究环境中铀、镎、钚等长寿命放射性核素的精密测定，对保护公众安全和保护环境，对了解核设施的历史操作情况和现状，都具有重要意义。环境样品基体复杂，铀、镎和钚等锕系元素含量非常低，在复杂的生态条件下，这些核素常常具有复杂多变的化学形态，要准确测定其含量，必须要有灵敏可靠的检测方法。

Save United States wilderness: Old-Growth in the Cascades; western U.S. wilderness; Palmyra Atoll with 16,000 acres of reef

This research is to provide a new ＂drug＂ that the paramagnetic radioactive isotopic nanometer-iron for treatment tumor, it have some characteristics comprising the paramagnetism and the radioactive activity, it can be located to the position of focus with three-dimensional rotating magnetic field.

本文提出一种新型的抗肿瘤药物——顺磁纳米铁核素，它具有超顺磁性、放射性活度和较好的磁导向功能的特点，在引导磁场的作用下可有效定位于靶区。

Ironically it was Irène Joliot-Curie, the daughter of Marie and Pierre Curie who first isolated polonium in 1898, who was the first to die because of exposure to it.

具有讽刺意味的是这个死者就是1898年首次分离出钋元素的居里夫妇的大女儿伊伦-约里奥-居里。她是因为长期接触这种放射性元素而死亡的。

Results The choroid plexus, hypophysis, area postrema and pineal body, namely, circumventricular organs and ependyma as well as pia mater layers were stained by the HRP reaction products.The HRP reaction products were observed in the tissue space of membrane mucosa nasi, around the fila olfactoria and venules, and within the venules under the light microscopy and electron microscopy, also. Scintillation count showed that the radioactivity of the CVOs was higher than that of the background. The radioautography showed that the scattered grains of silver existed within the cells of neurocyte layer also.

结果 在脑室周围器官及脑室周围室管膜、软脑膜层有HRP反应产物的聚集，在鼻中隔的鼻粘膜下组织间隙、嗅丝周围间隙及静脉周围和管腔内也可见到HRP反应产物；液闪计数显示，大白鼠的脉络丛、脑垂体、最后区、松果体等脑室周围器官放射性活度明显高于本底；放射自显影显示大白鼠脑组织神经层细胞内有散在分布的银颗粒。

Article 307While consigning for transport such dangerous goods as inflammable, explosive, toxic, corrosive or radioactive articles, the consignor shall, in accordance with the regulations of the State on the transport of dangerous goods, properly package the dangerous goods, affix thereto warning signs and labels, and submit to the carrier written documents concerning the name, nature and precautional measures relevant to the dangerous goods.

第三百零七条托运人托运易燃、易爆、有毒、有腐蚀性、有放射性等危险物品的，应当按照国家有关危险物品运输的规定对危险物品妥善包装，作出危险物标志和标签，并将有关危险物品的名称、性质和防范措施的书面材料提交承运人。

From their work emerged the picture of radioactive decay that is still valid-a violently disruptive explosion of a single atom.

根据他们的工作，展现出至今仍然成立的关于放射性衰变的图象--单个原子的强烈的分裂性爆炸。

Foreman: Now, I'm injecting a material that's tagged with a radioactive isotope. It's gonna enter your spine and travel up to your brain. It'll make you able to think deep thoughts, at about 100 miles per hour.

福尔曼：我现在要给你注射一些混合了放射性同位素的物质，它将通过你的脊髓进入你的大脑，把你带入深度思考状态，大约每是小时推进100英里的速度。

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。
