查询词典 cellular fission

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。

And, although scientists at Livermore and elsewhere were hard at work at it, so far as I know we have never developed a true "neutron bomb", that is, a "zero-fission fusion" weapon.

尽管Livermore还有其它一些机构的科学家们在这方面已经进行了大量研究工作，但就我所知，现在我们仍没有开发出真正的"中子弹"，即一种"完全的核分裂聚变"武器。

Measurements were also completed for neutron flux distribution and average fission fraction of 235U isotope in depleted uranium sphere.

测量了14MeV中子通量分布和贫化铀球中~(235)U同位素的平均裂变数。

When the distribution of important fission products is calculated, emphasis is placed on the noble gas radionuclides and upon radioisotope of iodine because of their great contribution to accident dose.

在对重要裂变产物分布的仿真计算中，重点放在了惰性气体核素和碘的放射性同位素上，因为它们是事故中放射性剂量的重要来源。

Single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered plants.

单细胞或无细胞的球状或螺旋状或棒状的缺乏叶绿素的有机体；通过分裂繁殖；和病原体一样对生物化学很重要；很难分类；通常被认为是植物。

Nuclear fission would have been a dramatic discovery at any time.

在任何时候，原子核裂变都会成为引人注目的发现。

Cadmium has the ability to absorb neutrons, so it is used as a barrier to control nuclear fission.

镉有吸收中子的能力，所以它被用作防止核裂变的屏障。

People capable of genetic engineering and nuclear fission obviously require all the spiritual and ethical guidance they can get.

从事遗传工程和原子裂变的人们显然需要所有他们能够得到的精神和伦理指导。

One of the methods to set free the energy locked in such substances as uranium is known as nuclear fission.
