isotopes

1.isotopes that emit radioactive particles; a stove emitting heat.

发射出放射性粒子位素；发出热量炉子

2.The researchers found that isotopes from the shock front were mixed into the protosun in a manner consistent with their origin in a supernova.

研究人员发现，激波阵面中位素混合到原太阳中，混合方式跟起初在超新星中时候一致。

3.The radiochemical separation procedure of ~(132)I was designed on the basis of half-lives of iodine and tellurium isotopes in mixed fission products.

依据混合裂变产物中碘及其母体碲位素半衰期设计分离132I。
