1.Spectral analysis methods were used for the analysis of the throughfall distribution series, and the results are. the spatial distribution pattern of throughfall is mainly determined by the spatial distribution pattern of the canopy structure, periodicity has been found in the series, and it is cau- used by the periodicity of the canopy structure, but it has no evident relation to the periodicity of the trees spatial pattern.
对林下降雨分布的实测数据进行谱分析后得出结论:林下降雨的空间分布形式主要由林冠结构的空间分布形式决定,随着降雨量的增加,这一点表现得越来越明显; 林下降雨的空间分布具有周期性,这种周期性是由林冠结构特征的周期性决定的,它与林木空间格局的周期性之间无明显关系存在。

5.American New Economy made the compatibility larger among high increasing ratio,low unemployment ratio and low inflation ratio, and it made the Phillips Curve of traditional economy theory noneffective; New Economy has the characteristic of increasing magrginal benefit, and the law of descending magrginal benefit of traditional theory was no longer the leading law; in New Economy times,knowledge became the most important force which advanced the economy and the knowledge which being an absolute inside variable has entered the increasing mode;New Economy made the characteristic of economy periodicity inapparently and made the wave of economy peridicity microwaved; New Economy brought forward some new problems on perfecting stat.of national economy.
美国新经济使高增长率、低失业率、低通货膨胀率三者之间的兼容度增大,传统经济理论中的菲利蒲斯曲线失灵;“新经济”具有边际效益递增的特点,传统经济理论中的边际效益递减规律不再成为起主导作用的规律;“新经济”时代,知识成为推动经济增长最主要的动力,知识作为一个独立的内生变量进入增长模式;“新经济”使经济周期性特点不显著,经济周期性波动微波化;“新经济”对完善国民经济统计工作也提出了一些新问题。

8.Rhythmicility or periodicity of the depositional strata is influenced by the fluctuation of sea-level to a certain extent, but it must be the response of depositional course to the structural activity in extensive significance.
研究表明,沉积岩层的韵律性或旋回性特征在一定程度上受海(湖)平面变化影响,但从更加广泛的意义上来看,应是沉积过程对于区域地质背景波动的响应,其主控因素是构造波动。
9.The whole paper consists of three parts: part Ⅰ is about general theory of the least positive period, which argues the necessary and sufficient condition for the existence of the least positive period for a periodic function, and concludes "the existence of the least positive period for that periodic function, which is continuous at least one point and not equal ever to a constant"; Part Ⅱ researches the least positive period for the sum of two periodic functions, followed its general expression; part Ⅲ discusses non-periodicity for the compound function constructed by a periodic function and a non-periodic function, and the corresponding results.
