辐射

In microbeam experiment, cells on a dish are individually irradiated by a predefined exact number of alpha particles, allowing the effects of exactly one alpha particle traversals to irradiate significant numbers of cells.

荷电粒子微束(Charged-particle Microbeam)是一种将粒子束斑的直径限制在微米量级范围内，并将预定个数的粒子注入到细胞中某一特定位置一种辐射装。。。

When surface alpha ray flux of color-glazed tiles are less than 0.0075Bqcm〓, the specific activities of 〓Ra are in the range of limits of this paper.

当表面α辐射水平低于0.0075 Bqcm〓时，彩釉砖的釉面料中的〓Ra放射性比活度在本研究的限值范围以内。

The alpha spectrometer is the important instrument to measure alpha ray pollution, mainly used in radioprotection, environmental samples, medical and health, agricultural sciences, import and export commodities inspection, geological exploration, nuclear power plants to survey alpha pollution.

谱仪是测量α射线污染的重要仪器，主要用于辐射防护、环境样品、医药卫生、农业科学、进出口商品检验、地质勘探、核电站等领域的α污染测量。

With the discovery of the radio-elements, physicists found themselves for the first time confronted with strange substances, minute generators of radiation endowed with an enormous concentration of energy; alpha rays, positively charged helium atoms, beta rays, negatively charged electrons, both possessed of a kinetic energy which it would be impossible to communicate to them by ''.

由于放射性元素的发现，物理学家们第一次发现自己面临许多陌生的物质——许多具有巨大的浓缩能量的、能够发生辐射的细微物质，如射线，即带正电荷的氦原子小射线，即带负电荷的电子。

It now appears that Amalthea's density is only about the same as water and since it is unlikely to be composed of ice it is most likely a loose rubble pile with a lot of empty spaces.

与木卫一类似，木卫五辐射出的热量比从太阳处收到的多（可能是因为木星磁场感应出的电流的关系）。

As recently as last November, in its last encounter with a Jovian moon, tiny Amalthea, the spacecraft " got hammered again by radiation," Dr. Alexander said.

去年十一月份，在它的最后一次与木星的卫星木卫五相遇时，"飞船又被辐射给破坏了，" Alexander博士说。

Vitamin A not only can synthesize inspect amaranthine qualitative, it is clearer to still can make the eye sees a thing below dark light, accordingly, green tea not only can eliminate computer radiant harm, still can be protected and raise eyesight.

维生素A不但能合成视紫红质，还能使眼睛在暗光下看东西更清楚，因此，绿茶不但能消除电脑辐射的危害，还能保护和提高视力。

The center cities play an extremely important role of amassment and radiation in the development of the district economy.

中心城市是在经济上有着重要地位、政治和文化生活中起着关键作用的城市，它具有较强的吸引能力、辐射能力和综合服务能力。

This is the standard used by cell phone companies, among others, to measure levels of radiation.

这是标准所使用的移动电话公司，除其他外，衡量的辐射水平。

On the basis of the simplified differential equations, analytical solution of the radiation damping coefficient for a thin layer is derived, and then a simplified formula taking into account of a number of important influence factors is obtained.

求解了薄层辐射阻尼的解析解，并拟合了包含足够信息同时又便于使用的近似公式。

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。
