     Ultra high cycle fatigue behaviors of 54SiCrV6 and 54SiCr6 clear high strength spring steels were investigated and their fractographs were observed by means of field emission scanning electron microscope (FESEM) and electron probe microanalyzer (EPMA). Experimental results show that for the two steels, the fatigue failures originated from the matrix of sample surface at high stress amplitude and from sample interior at low stress amplitude.

Abstract

本文根据1:5万中峰公社幅及百里村幅区调资料,系统地采集了2080个岩石样品,用光谱半定量测定了22个元素。对不同时代不同期次花岗岩中微量元素的分布特征进行了研究,并对其含矿性进行了评价。

In the regional surveys of the Donggu Sheet at a scale of 1:50,000 in central Jiangxi,abunant microfossil plants were for the first time collected in the upper Sinian Laohutang Formation and the Lower Cambrian Niujiaohe Group,thus providing paleontological evidence for the classification of this sequeuce of strata.The microfossil plants of the two formations have their own peculiarities,but have some common elements too.This shows that the deposition of the Sinian and Cambrian were continuous.

赣中1:5万东固幅区调,首次在上震旦统老虎塘组和下寒武统牛角河群采获丰富的微古植物化石,从而为这套地层的划分提供了古生物佐证。两组微古植物各具特色,但也存在一些共同分子,表现为连续演化的特点,说明震旦系和寒武系的沉积是连续的。

In arid and semi aird region of China,precipitation between irrigation plantation region and non -irrigation plantation region is 150-200mm in the monsoon climatic region and 100-150mm in the Mediterranean climatic region. In the area where precipiation is less than their limit precipitation, non —irrigation plantation should be carried out;where the groundwater table is lower than 4-6m it suits to plant trees and lower than 5-10m for xeric shrubs (dwarf trees). Mineral content of groundwater is less than 3g/l....

In arid and semi aird region of China,precipitation between irrigation plantation region and non -irrigation plantation region is 150-200mm in the monsoon climatic region and 100-150mm in the Mediterranean climatic region. In the area where precipiation is less than their limit precipitation, non —irrigation plantation should be carried out;where the groundwater table is lower than 4-6m it suits to plant trees and lower than 5-10m for xeric shrubs (dwarf trees). Mineral content of groundwater is less than 3g/l. for salt-avoiding trees and 3-8g/l. for salt-avoiding shrubs.

本文根据“三北”防护林体系建设中的理论研究和实践经验得出:①我国“三北”防护林体系荒漠半荒漠区无灌溉条件下造林的降水极限,在大陆性季风气候区为150—200mm。在地中海气候区,为100—150mm。②最大根幅区的降水收入与水分支出平衡时的降水量,就是理论上无灌溉条件下造林的降水极限。③水平根系越发达,无灌溉、无地下补给条件下植物的抗旱性越强。较小的造林密度有利于脆弱的水分平衡。④耐旱乔木造林的地下水埋深极限为4—6米;耐旱灌木(小乔木)为5—10m。耐盐乔木的矿化度极限为3g/l;耐盐灌木为3—8g/t。
