Subsequently, in August 1949 the former Soviet Union also conducted an atomic test in October years .1952 3, United Kingdom, in February 1960, France, October 16, 1964 China has conducted an atomic test, breaking the U.S. nuclear attack off .1950 10 31, the United States conducted in liquid deuterium to hydrogen fuel for the heat theory test, but a nuclear device is very bulky and can not be used as weapons .1953-year in August, the former Soviet Union conducted in order to solid-state lithium deuteride -6 for the hot nuclear fuel hydrogen bomb test, so that practical hydrogen bomb is possible.

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。

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.

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。
