The central government came to a new high level of recognizing the science and technology after 1978, thus, a new policy of clerisy was established and a good political atmosphere, which benefits on popular science development, was formed. Besides, while the government's essential mission was transferred to economical construction, the popular science was accelerated by factors as economical development, social desire and economical treatment. Then, the prosperity of education set a good foundation for the development of popular science. Fourthly, the increase in the number of boffins and a fast advance on science and technology contributed to popular science's development intellectively. All these elements above caused the 2nd fastigium. However, during the last 1980s and early 1990s, confusion occurred to man's sense of worth in the period of economy transformation, which made popular science come to a downturn. As a result, the 2nd fastigium declined.

第四章对第二次科普高峰进行了分析。1978年以后，党中央对科学技术的认识达到了前所未有的程度，确立了新的知识分子政策，形成有利于科普发展的良好政治氛围；国家工作重心转移到经济建设上来，经济发展、社会需求和经济待遇等因素促进了科普的发展；文化教育事业的兴旺发达为科普的发展奠定了良好的基础；科技工作者队伍的壮大，科学技术的迅速发展，提供了科普发展的智力支持，这些综合因素促成了第二次科普高峰的到来。80年代末期到90年代初，由于在经济转型期出现了暂时的价值观混乱，科普工作陷入低迷，科普高峰消退。

Middle period up to 21 centuries, the our country will face the bearer oscular three greatest high peaks one after another, then the employment high peak and advanced age of the population total amount high peak, population turn population high peak, pollution of the environment of rigorous also turn worse a land resources can keep on the necessity of exploitation.

到21 世纪中叶，我国将相继迎来人口的三大高峰，即人口总量高峰、人口就业高峰和老龄化人口高峰，环境污染的严峻也加剧了土地资源可持续利用的必要性。

When the first summit of industrialized democracies first took place back in Rambouillet, France in 1975 there were only six members, hence it was then known as the G6 Summit. In 1976, Canada joinedmaking it G7 and the European Union has been invited to take part in the summit since 1977. But it wasn't until Russia joined in 1998 that the G8 Summit adopted the format still used today.

回顾当初八大工业国高峰会议於1975年第一次在法国RAMBOUILLET成立的时候，成员只有六个，当时也被称为G6高峰会议。1976年，加拿大加入使得高峰会议成为G7，欧洲联盟则於1977年起被邀请参与G7的会议，而俄罗斯最后在1998年加入使得高峰会议变成G8。

从油菜角果发育过程中角果含水量、乙烯合成速率、外切 PG 酶和内切纤维素酶活性，以及角果裂区切片观察等方面研究了角果开裂敏感性形成的原因⒚花后50d 的角果果柄端壳状果瓣和线状果瓣间的裂区薄壁细胞膨大，在高倍光学显微镜下可见胞间空隙开始形成⒚此前6d 内乙烯合成速率迅速上升并出现第二次合成高峰，与之同步发生外切 PG酶和内切纤维素酶活性急剧上升，而乙烯合成第二高峰出现于角果含水量低于80％以下⒚由此看来，角果失水引起乙烯合成第二高峰出现，从而导致水解酶活性上升，最终导致果瓣裂区薄壁细胞膨大，分离和胞间空隙形成及角果开裂敏感性产生

Vivipara under different weather conditions all showed two peaks, there still existed differences in the beginning and standing time of their activities, the appearing and standing time of the activities peaks, and the values of the peaks. In fine days, the beginning time of the activities was earlier, and the duration and interval time were longer; while in cloudy days, the duration for activities was shorter, and the appearance frequency of activities peaks was higher. The males devoted more time to activities and appeared more at activities peaks than the females, while the juveniles began activities later and appeared lesser than the adults.
