钚

Mainly use the -235 uranium or plutonium -239 and other heavy nuclei fission chain reaction mechanism made of nuclear weapons, known as fission weapons, or atomic bomb.

主要利用铀－235或钚－239等重原子核的链式裂变反应原理制成的核武器，叫做裂变武器，或称原子弹。

A highly fissionable isotope of plutonium that is used in atomic weapons and as a reactor fuel; produced by irradiating uranium 238 with slow electrons.

钚的一种极易裂变的同位素，用于核武器或作反应堆燃料，用慢电子辐照铀获得。

Pyongyang threatened to restart its Yongbyon nuclear reactor and to begin reprocessing fuel rod s, which would increase its stockpile of weapons-grade plutonium .

平壤方面威胁重启其宁边核反应堆，并开始对燃料棒进行再处理，此举将增加该国武器级钚的库存。

The concentration of neptunium and plutonium is extremely low in environmental samples. Additionally such samples have a complex matrix composition, which is to be taken into account for a proper analysis.

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。

Since 1980s, ICP-MS has been used overseas for the determination of uranium, thorium, neptunium, and plutonium in environmental samples. ICP-MS is one of the most suitable analysis techniques for the measurement of the long-lived radionuclides.

自八十年代以来，国外对ICP-MS测量环境样品中的铀、钍、镎和钚的研究表明，ICP-MS在测量长寿命放射性核素方面是最有发展前景的测量技术之一。

Study of thermal, force and nuclear radiation of weapons-grade-plutonium is one of the essential problems faced in the research of whole-device-storage of nuclear weapons.

武器级钚的热、力、核辐射作用是核武器整装贮存研究面临的关键课题之一。

In November 2008, the country began to recreate its nuclear reactor.

在2008年11月，朝鲜开始重建核反应堆，恢复钚的生产。

He was to stop making plutonium as well as suspected work on uranium.

他也被要求停止钚以及铀等可疑项目。

In this sense only, more nuclear tests would actually help, by using up what plutonium is left.

仅从这个角度来看，更多的核试验实际上是有意义的，可以耗尽剩下的钚。

Plutonium, of course, can be used to make nuclear weapons.

当然，钚可以用来制造核武器。

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。
