A comparative study of pollen floras between two cores: Core 17940 from the northern slope of the South China Sea and a core from the Toushe Basin in central Taiwan Province, reveals that there were three different vegetation types around the two areas during 15-40kaBP. The first type is characterized with the subtropical evergreen broadleaved forest during MIS2 (20-15kaBP). The second is the Pinus/Alnus-dominated woody plant communitites, corresponding to an interstadial summer monsoon dominated warm and humid climate and higher sea/lake level. The third is the Artemisia/Poaceae-dominated herb communities, corresponding to a stadial winter monsoon dominated warm and dry climate and lower sea/lake level.

根据南海北部17940孔和台湾中部头社孔孢粉序列对比结果，首次提出了华南地区15-40kaBP期间的三个具代表性植物群：1以青栲类为主的亚热带常绿阔叶林为第1植物群，该植物群在MIS2阶段(20-15kaBP)，为南海北部周边地区和台湾中部头社盆地周围地带性植被；2以松属或桤木属为主的木本植物为第2植物群，对应于间冰阶，夏季风盛行，降水充沛，气候暖湿，高海面；3以蒿属或以禾草为主的草本植物为第3植物群，对应于冰阶，冬季风盛行，降水少，气候暖干，低海面。

For the study of Brownian motion established kinetic theory of gases played an important role in the process of .1827, Brown observed that pollen suspended in water such as the random motion of material particles .1877 year, Delta claims that the particles The irregular movement of liquid molecules to its collision-induced .1905 imbalance and later years, Einstein, Langevin Smolukhovski, and they were published on the theory of Brownian motion .1908 year, Perrin Experimental observation of the system, confirmed the correctness of the theory.

对于布朗运动的研究在气体动理论建立的过程中起过重要作用。1827年，布朗观察到悬浮在水中的花粉等物质微粒的无规则运动。1877年，德耳索指出，微粒的不规则运动是液体分子对它的不平衡碰撞引起的。1905年及稍后，爱因斯坦、斯莫卢霍夫斯基和朗之万分别发表了他们关于布朗运动的理论。1908年，佩兰的系统实验观察，证实了上述理论的正确性。
