| 释义 | ballooning noun[ U ] uk /bəˈluː.nɪŋ/ us /bəˈluː.nɪŋ/ the sport or hobby of flying in a hot-air balloon(= a very large bag that is filled with hot air or gas and can carry people in a basket (= open container) hanging under it): Ballooning caught the public's imagination with some high-profile long-distance events. The annual ballooning festival will be bigger than ever this year. The country has been one of the leaders in the sport of ballooning. Ballooning is one of the big draws for tourists in New Mexico. I'd love to go ballooning one of these days.

It seems quite unlikely that spiders can travel 5000 km in one ballooning event. This knowledge is then incorporated into the current evolutionary phylogenies to examine how ballooning might have arisen. Inflation did pick up somewhat after the presidential election, perhaps because of inflationary expectations created by the ballooning of government debt. Also, for the high-n ballooning modes, the trapped electrons reduce the pressure perturbations. Secondly, ballooning spider mites are strongly polyphagous and widely distributed in many types of habitats. For spider mites and moth larvae, ballooning is generally used to facilitate local dispersal. The evolutionary discussions take the form of an orderby-order treatment of the ballooning behaviours and the ecological phylogenetics of spiders, spider mites and moth larvae. Normally, the calculation of ballooning mode stability is complicated, requiring information about the plasma equilibrium and geometry. That said, there are still differences between spiders and the other two ballooning orders. Other scholars have concentrated on individuals or local efforts with a particular emphasis on ballooning firsts or ballooning disasters. A handful of biochemical studies have highlighted the effects of ballooning on population genetics, helping to improve our understanding of the settling distribution. Environmental conditions (food supply and temperature, both immediate and during development) explained more variation in ballooning latency than did family lineage (genotype). It may be that ballooning is not attempted in conditions where the probabilities of remaining within the air column become too high. However, ballooning is different from all other dispersal modes because it is inextricably linked to an individual's ability to produce silk.
