It examines how atoms of a gas behave at extremely low temperatures , in a theory developed in collaboration with indian physicist satyendra nath bose 这份手稿研究了在超低温情况下气体原子的运动情况，这是爱因斯坦和印度物理学家玻色共同合作提出的有关量子学说的一项重要理论。
This is because the magnets used to accelerate the particles to the high energies needed for particle physics rely on the phenomenon of superconductivity to work ? and superconductivity , in turn , needs extremely low temperatures 这是因为磁铁加速粒子到高能量是需要在超导条件下进行的，而超导是需要在超低温下进行。
Advances in the techniques for cryopreservation of " musa " . including germplasm embryogenic cell suspension , zygotic embryos and apical meristems over ten years are reviewed ; and the main factors affecting cryopreservation are also mentioned , which include material , pretreatment , loading and dehydrating 总结了影响香蕉超低温保存效果的几个主要因素，主要包括材料、预处理、装载处理以及冰冻保护剂。

With the development of the technology of cell culturing and cell engineering , so it is possible to preserve fish species for a very long time . 3 ) using embryonic stern cells ( es ) . fish embryonic cell has the totipotency and is better f or breeding than somatic cell , but it can not so strong to resist the very low temperature 三是通过es途径。鱼类胚胎干细胞具有发育的全能性，利用鱼类胚胎细胞育种比体细胞更具有优越性，但耐超低温性不强，只有少数学者对鱼类胚胎细胞进行冻存及发育潜能的研究，还没有对鱼类胚胎细胞进行冻存培养的系统研究。
