粒子

Using the mechanism of the nuclear reaction of accelerated 7Li +3 ions with the inner target in mutant material i.e 1H( 7Li, 7Be)n, the biological effects were studied. The wheat seeds were irradiated with the doses ranged from 1.416×10 10 ions/cm 2 to 1.416×10 12 ions/cm 2. It was found that the cell membrane ruptured, the plasmolysis occurred, the nucleus shape changed.

将加速器7Li+ 3 离子束与生物体内遗传物质发生1H( 7Li，7Be)n内靶特征核反应诱发核酸分子结构变化的机制应用于生物诱变，辐照剂量在 1 41 6× 1 0 10 粒子 cm2 - 1 41 6× 1 0 12 粒子 cm2范围内处理的小麦，观察幼苗叶片细胞亚显微结构，发现离子束注入引起了细胞膜的破裂，细胞发生质壁分离，细胞核形状变得不规则等。

These have the mathematical structure of the corresponding one-body equations (Klein-Gordon for two spinless particles, Dirac for two spinor particles) with a relativistically reduced mass.

这些有相应那个身体方程式(克莱因戈登适合二spinless 粒子，迪拉克适合二spinor 粒子)有降低群众的relativistically的数学结构。

The nature of the nuclear transformation could be firmly established: the aluminium atom, for example, captures the alpha particle and is transformed, after expelling the proton, into an atom of silicon .

核蜕变的性质因此得到确立。例如，铝原子俘获。粒子，并在排出质子后蜕变成硅原子。

"Beta particle:a high-speed electron or positron, especially one emitted in radioactive decay ."

粒子：一种高速电子或质子，主要在放射衰变中释放出。

"Beta particle:a high-speed electron or positron, especially one emit ted in radioactive decay."

粒子：一种高速电子或质子，主要在放射衰变中释放出。

"Eta particle:a neutral elementary particle that has a mass 1,074 times that of an electron."

粒子：质量为电子的1074倍的中性基本粒子。

The electron line itself in a Feynman diagram represents a "bare" electron ,whereas the real observable particles are the "bare" particles "dressed " by these virtual processes,the so-called"self-energy" terms which contribute to the mass and charge of the electron that the experimentalist measures.

一个 Feynman 图表的电子线本身表现"赤裸的"电子，然而真正的观察得出的粒子是被这些虚拟的程序穿着的"赤裸的"粒子，那所谓的"自己的-能源"成为块和实验者测量的电子费用的因素期限。

The animals were divided into two groups before the implantation of the iodine-125 granule into the tumor mass: control group (n=40, to implant no-load seeds, non-iodine-125 radioelement) and experimental group 〔n=40, to implant iodine-125 seeds (1.48×107 Bq) when the length of tumor was 8-10 mm〕.

采用雌性BLAB/c-nu/nu裸小鼠建立人类乳腺癌MCF-7细胞株的裸鼠皮下移植瘤模型，将荷瘤鼠分为2组，对照组（n=40）：植入空载粒子，无125I 放射性元素（0 Bq）；实验组（n=40）：瘤体长径达8～10 mm时植入125I 粒子（1.48×107 Bq）。

All rocks release large fraction of argon between 300 and 700℃ except garnetiferous mica schist. The amount of argon released between 700 and 1100℃ has a positive relation to Ca/K value on the whole. The saturation implantation dose of rocks in this experiment is～10〓 ions/cm〓.

除含石榴石云母片岩氩放气峰在900℃以外，其它岩石都在300-700℃放出大部分氩气，所有岩石在1100℃以下都释放了其中大部分的氩气。700-1100℃放出的氩气量基本与Ca/K呈正相关关系。120keV氩离子注入多种岩石的饱和剂量为～10〓粒子/cm〓。

This deficit indicates that there may be "baryonic" dark matter (although not enough to make the universe recollapse), as well as the more exotic "particle" dark matter.

这缺额显示可能存在&重子&暗物质(虽然不足于使得宇宙重新坍缩)以及更奇异的&粒子&暗物质。

Article 144 The Government of the Hong Kong Special Administrative Region shall maintain the policy previously practised in Hong Kong in respect of subventions for non-governmental organizations in fields such as education, medicine and health, culture, art, recreation, sports, social welfare and social

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

Small wonder, then, that the Chinese spend more in the shop than any other group of foreign visitors do .

这样的小惊喜，使中国顾客比任何国家的人消费得更多。
