随后，1949年8月原苏联也进行了原子弹试验。1952年10月3日英国、1960年2月法国、1964年10月16日中国先后进行了原子弹试验，打破了美国的核袭断。1950年10月31日，美国进行了以液态氘为热核燃料的氢弹原理试验，但核装置非常笨重不能用作武器。1953年8月，原苏联进行了以固态氘化锂－6为热核燃料的氢弹试验，使氢弹的实用成为可能。

Nuclear fusion of deuterium and tritium at high temperatures releases enormous amounts of energy.

高温下氘和氚的核聚变释放巨大的能量。

In the process of Coulomb explosion, the kinetic energy of deuteron could be calculated as a function of deposited energy and dielectric constant.

以此同时区域内会产生高温高压现象，因此在这种环境下高能的氘氘离子有可能产生核聚变。

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

As a special form of polymer, the perdeuterated polymer foams not only have the microporours structure and good capabilities as same as nondeuterated polymer foams, but have some particular characters, such as isotope effect, nonradioactivity, and high deuterated ratio. For those reasons, the perdeuterated polymer foams will be used in many fields, especially in inertial confinement fusion and low wastage plastic.

全氘代聚合物泡沫作为一类特种聚合物材料，不仅具有常规聚合物泡沫材料所具有的微孔形貌和良好的物理化学、机械力学等性能，而且还具有独特的同位素效应，以及非常高的氘代率等特征，且无放射性，因而在激光惯性约束聚变(Initial Confinement Fusion，ICF)热核靶材料，以及低损耗塑料光纤材料等研究领域中具有十分广泛的应用前景。

Antiparticles are created elsewhere in the universe where there are high-energy particle collisions, such as in the center of our galaxy, but none have been detected that are residual from the Big Bang, as most normal matter is [1] ( http://science.nasa.gov/headlines/y2000/ast29may_1m.htm ).

科学家在1995年成功生产了氢的反原子，以及反氘核核子，由一个反质子和一个反中子生成，仅仅还不能是更为复杂的反物质。
