Their developing process went through four major periods. They are the germination period in ancient Greece, the forming period from 17 century to 19 century, the revival period during 1920"s and 1930"s in America, and the whoopee period during 1970"s and 1980"s which the contemporary naturalism philosophy of science developed sufficiently.

其发展大致经历了四个时期：古希腊萌芽时期；十七——十九世纪的形成思潮时期；二十世纪二、三十年代在美国的再度兴起以及在同世纪七、八十年代得以充分发展的当代自然主义科学哲学。

The period from October 1935 to March 1948 was named Yanan period in the history of the CPC.

延安时期是中国共产党和中国革命历史上一个非常重要的时期，是在中国革命经历了曲折之后逐步走向全国胜利的时期。

Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

涝渍是玉米苗期主要的非生物逆境胁迫之一；本试验通过对20份玉米自交系进行苗期的淹水对照试验，采用了三个处理时期，并利用耐渍系数作为指标进行敏感时期的鉴定，结果表明三叶一心期是淹水的相对最佳时期；同时利用其中10份自交系对耐渍系数的重演性进行了分析，结果表明其重演性很好；同时结果还表明耐渍系数是耐渍性鉴定的一个可靠指标。

Whereas, the tapetum of Zhenshan 97A disaggregated at the pollen mother cell stage, the nuclear membrane and the cell membrane disaggregated, the phenomena continued to the binucleate pollen stage. The cytoplasm of the tapetum cells of Zhenshan 97A deposited a few Ca^2＋ precipitates at the pollen mother cell stage.

珍汕97A绒毡层细胞从花粉母细胞时期开始，细胞质内有少量颗粒状的Ca^2＋沉淀；减数分裂时期，绒毡层细胞的内切向壁表面有大量大颗粒的Ca^2＋沉淀；单核花粉时期绒毡层细胞周围集聚一层Ca^2＋沉淀。

The four protozoa had different changing patterns in rhizosphere and nonrhizosphere soil. About 90 times more Colpoda were determined in rhizosphere than in nonrhizospher at 52 days after sowing. There were more Anweba in rhizosphere than in nonrhizosphere at 74 days after sowing. Much more Bodo were found in rhizosphere at 32 days alter corn sowing. However, the number of the Bodo in rhizosphere soil was only 10% of that in the nonrhizosphere soil at 52 days after sowing. Rhizosphere always contains more Cercomonas than nonrhizosphere within the whole growing season of corn.

不同的原生动物的根际效应差异很大，肾形虫在抽雄期R/S比接近90；变形虫在吐丝时期表现出一定的根际效应；波豆虫在大喇叭口时期表现出比较强烈的根际效应，但在抽雄期则表现出十分强烈的负根际效应，根际土壤中波豆虫数量不到非根际土壤的10%；尾滴虫在玉米整个生育时期都表现出微弱的根际效应。

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

雀莫错组在羌北盆地为近海湖泊沉积，更具海相色彩：南羌塘主要为外陆棚沉积，反映羌塘盆地再次发生较强烈的裂陷作用和较大幅度的海平面上升，形成陆源剥蚀区缩小，沉积覆盖面增大的古地理面貌。4、根据地层界面特征、地层划分与对比结果和岩相古地理演化特征可将晚三叠世—中侏罗世早期羌塘盆地划分为两个不同构造性质的盆地发展时期，分别为晚三叠世卡尼期—若利早期的残留内陆表海沉积盆地发展与消亡时期和晚三叠世若利期中晚期—中侏罗世早期的裂陷盆地的形成与发展时期。

Along with the mining industry declining, the settlement distribution, the population aging (in 96 year Tongshan Village old person ratio nearly 30%) with industrial reforming, under such environmental chane, Japanese Colonial Periodaround the time, the gold ore prosperous time, after the Recession of Taiwan in the recovering time historical vein, the substantive space, how does the social space's change live regarding the place maintains with is balanced; How between the reciprocity to achieve settlement old person each other's interaction and the familiar environment?

随著矿业的没落，聚落的分布，人口的老化(96年铜山里老人比率近30%)与产业的转型，在这样的环境变迁下，日治时期前后、金矿兴盛时期、光复时期之后的历史脉络里，实质空间、社会空间的改变对於地方之居住如何相维持与平衡；相互关系之间如何达到聚落老人彼此的互动与熟悉的居住环境？

As the constitutionalization of the general line of the interim,the content of the constitution fully mani2fests the characteristics and requirements of the interim.The reason why the 1954constitution was not truly carried out later is closely related to the warp of the theoretical cognition during the interim.
