| 1. | Observations do not indicate that cloud nucleus concentrations parallel those of sulphur dioxide .
观测没有表明云核浓度与二氧化硫浓度相关。 |
| 2. | It is legitimate to envisage a more or less one-to-one correspondence between cloud nucleus concentration and the concentration of cloud droplets .
拟想云核浓度与云滴浓度之间有或多或少的一一对应关系是合理的。 |
| 3. | Brown dwarfs can then form directly from ultralow - mass cores
棕矮星因此能够在超轻云核里形成。 |
| 4. | A sufficiently large and dense core can overcome the outward force of gas pressure to collapse under its own weight
够广大且够致密的云核，会以自身的重量克服向外的气体压力而崩塌。 |
| 5. | Cores , they argued , can be even smaller because turbulent motion within the molecular cloud can trigger gravitational collapse
他们推论认为分子云内的乱流可以引发重力坍塌，所以云核还可以更小一些。 |
| 6. | They questioned the usual assumption that star formation begins with cores containing at least one solar mass or more of material
他们质疑一般的假设：恒星形成起始的云核，含有至少一个太阳质量以上的物质。 |
| 7. | In this scenario , the multiple embryos in a core compete to accrete matter , and the one that grows slowest is at the mercy of the others
在这个学说里，云核中的多重胚胎竞相吸积物质，其中成长最慢的就成了牺牲品。 |
| 8. | Simply put , a small core that would not collapse when left to its own devices can be induced to do so when compressed by turbulence
简单的说，一个小云核虽然没办法靠自己的机制进行重力塌缩，但乱流却能施压帮助其坍塌。 |
| 9. | In the turbulence scenario , the sequence of events is the same for stars and brown dwarfs ; stars simply come from cores that happen to be larger , and brown dwarfs from cores that happen to be smaller
在乱流说里，恒星与棕矮星的演化序列完全相同；只不过恒星源自较大的云核，而棕矮星来自较小的云核。 |
| 10. | The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie , the thickness , the temperature and the supersaturation with respect to ice of the nucleation layer ) . this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water , the density of the supersaturation of the vapor with respect to ice . simultaneously , the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude , and elicits the proper seeding altitude of the catalyst
以此解为依据，得出了不同均流时，人工引入冰核在核化层存留时间，再以此时间作为人工冰核凝华增长时间，求出不同的云宏微观背景(如核化层厚度、温度、冰面过饱和度等)下的冰晶谱分布，经和实际资料比对符合相当好。进而求出核化层中不同过冷水量、冰面过饱和水汽密度下云核化层可允许的催化用量。同时讨论了不同升速，不同高度引入人工冰核时对其存留时间的影响。 |
