云核 meaning in Chinese
cloud nuclei
Examples
- 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。 - 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。 - 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。 - 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。 - 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。
