| 1. | The physicist was aware of the potential danger of nuclear fusion
那位物理学家意识到核融合潜在的危险。 |
| 2. | Conventional physics holds that nuclear fusion ignites at multimillion - degree temperatures
传统物理学认为，要引发核融合反应，必须将温度提高到数百万度。 |
| 3. | The head of the sperm cell and the nucleus of the egg cell then unite and form a new cell : the zygote
然后，精子的头和卵子的核融合，形成一个新细胞：受精卵。 |
| 4. | The superheated sun would release as much fusion energy in that hour as it normally does in 100 million years
过热的太阳在这一小时内释放出的核融合能量，可达正常情形下一亿年里所释出的量。 |
| 5. | In flowering plants the endosperm tissue is usually triploid , resulting from the fusion of one of the pollen nuclei with the two polar nuclei
在开花植物中，胚乳组织多为三倍体，由一个花粉核和两个极核融合产生。 |
| 6. | So when physicists tell us that stars generate light and heat from nuclear fusion reactions inside the stars , what evidences do they have
那么，当物理学家告诉我们，恒星藉著内部的核融合反应发光发热，究竟有甚么凭据？ |

| 8. | Positrons and neutrinos are produced during the process , and are the telltale trace of the nuclear fusion reaction inside the sun
V ，那就可以和另外一粒质子结合，释放能量。这过程产生正电子及中微子，它们是太阳内部核融合反应的印记。 |
| 9. | The fusion protein had expected primary structure . conclusion : pgex - 4t / mpem expression plasmid was constructed . gst / mpem fusion protein was successfully expressed
结论：构建了原核融合表达质粒pgex - 4t mpem ；成功在大肠杆菌中表达gst mpem融合蛋白。 |
| 10. | When a pollen grain germinates , a pollen tube pushes its way out through an aperture in the pollen grain wall , and the nuclei migrate into the tube
生殖细胞核分裂，形成两个仅由细胞核和细胞质构成的精子，其中一个将与卵受精，另一个则与极核融合形成胚乳核。 |
