高血压病与气象关系探讨

通过对高血压病与气象关系的分析表明，气温、气压等气象要素的急剧变化，均对高血压病产生影响。患病高峰期与气候月际变化最大期相吻合，说明高血压病发病与气象有关，即气象因子是高血压病的一个致病因素。     

微机遥感图像应用处理系统

本文详细介绍了我们研制的微机遥感图像应用处理系统。它的硬件部分以四台微机为主,采用分布式联接,组成四个子系统,可供1—4人同时操作,能方便地输入输出多种数据和图像。该系统的软件部分,由对应硬件子系统的四个软件包组成,即磁带机数据采集软件包,图像显示软件包,专题制图软件包及遥感应用处理软件包。作为重点的第四部分软件,是在遥感应用工作者的经验和工作方法的基础上设计的,它收集和综合了各种实用处理方法,比通用的图像处理软件包更具有遥感应用的特色。     

Rockfall hazard in the Daisekkei Valley, the northern Japanese Alps, on 11 August 2005

This paper describes a rockfall event in the Daisekkei Valley of Mount Shirouma-dake (2,932 m), the northern Japanese Alps. The rockfall occurred on a steep cliff comprising well-jointed felsites and produced debris of ≥8,000 m³. Most debris was deposited on an elongated snowpatch located immediately beneath the cliff, and it caused casualties among people who were trekking along a trail on the snowpatch. Additionally, a large rock block slipped 1 km on the snowpatch. The rockfall could have been due to the differential retreat of the rockwall, which contains areas of high- and low-density joints. Seasonal and diurnal freeze–thaw activities and snow avalanches and wash appear to be important factors responsible for the retreat. Although some rock blocks that can collapse further remain on the rockwall, the position of the mountain trail in the Daisekkei Valley is fixed. Fundamental reform of tourism systems for climbers, including education on natural hazards, is required.     

江苏省夏季气温异常的海气背景

通过1961－1998年江苏省11个站点夏季（6－8月）平均气温的EOF分析，探讨江苏省夏温异常的时空分布结构，并在此基础上，分析其前期及同期500hPa高度距平场、海温距平场的特征，得到了一些对本地夏季气温异常预测有意义的结果。     

青海唐古拉地区侏罗纪非海相双壳动物群及其古环境分析

唐古拉山温泉以东约80km的冬曲一带产出丰富的侏罗纪非海相双壳类化石,中侏罗统雀莫错组顶部的紫红色细粒岩屑砂岩产Qiyangia,Yunnanopharus,Unio 3属3种,其中有新种Yunnanopharus substratus.这一动物群与过去在本区发现的中侏罗统“Cuneopsis”-Eolamprotula-Protomya动物群面貌明显不同,过去一直认为Yunnanopharus是晚三叠世的属,而Qiyangia则主要产于下侏罗统,根据地层层序及上、下层位产出的海相双壳类和腕足类化石时代分析,冬曲剖面的Qiyangia-Yunnanopharus动物群时代无疑为中侏罗世巴通期,扎窝茸组产非海相双壳类“Cuneopsis”,Yunnanopharus,Plicatunio,Nipponaia(Eonipponaia),Cyotrigonioides,Danlengicon-cha,Nakamuranaia等7属9种,其中包括新种Yunnanoconcha(?)ovalis,Danlengiconha tanggu-laensis,Cyotrigonioides(?)ellipticus和Nipponaia(Eonipponaia)?bifurcata,基于下伏海相地层中双壳类和腕足类化石的佐证,它们的时代最有可能是在晚侏罗世基末里期至早白垩世期间,据化石围岩的粒度分析以及埋藏学研究表明,这些类三角蚌类主要生活于水体安静、有机质含量丰富的淤泥质基底,繁盛于近海三角洲平原上的湖沼环境,同时,由于海退初期尚有可能受到海水短暂侵漫的影响,造成它们生存环境的咸化     

层序地层研究产生的地层学新观点、新概念和新方法——兼论建立新一代年代地层表

层序地层学在地层划分、对比、分类和级别体系等地层学根本理论问题上给地层学带来了新认识、新概念和新方法。全球层型剖面和点(GSSP)可建在层序界面的整合部位,从而将传统的自然界线(或不整合面)、层序界面和GSSP三者有机结合起来,使得年代地层界线成为可在野外识别和追索的界线。论证了层序地层是独立存在于岩石地层和年代地层之间的地层类别和包含这三个基本地层类别的新的三重地层分类方案。阐述用层序地层界线优化各类原有年代地层和岩石地层界线的原理和方法,探讨和阐述了新的地层学体系和建立新一代年代地层表的途径和方法。     

南海到西太平洋地区水汽输送和山东夏季降水量奇异值分解分析

利用奇异值分解(SVD)方法和山东省26个代表站1951～2000年6～8月降水量、NCEP／NCAR再分析1958～1998年1～12月925～300hPa5层月平均比湿和风场资料,分析了山东夏季降水与前期(冬季、春季)及同期(夏季)南海到西太平洋地区水汽输送之间相关场的分布型,从中找出了遥相关的“关键区”,并对找到的“关键区”的可靠性进行了验证。研究表明,山东夏季降水与前期(冬季、春季)和同期(夏季)南海到西太平洋地区水汽输送相关较好,春季的相关程度最高,冬季次之,夏季最小。     

Chromium spinels in North Chinese kimberlites,Huabei platform

Samples from diamondiferous pipes in the Mengyin and Fuxian regions were investigated. The chemical compositions of Cr spinels in kimberlites of China were found to be similar to those in kimberlites of the Arkhangelsk province in Russia. A long and complex evolution that was individual for each pipe was demonstrated. The kimberlites of the Shandong Province proved to be rich in high-Cr chromites. This means that the kimberlites formed at large depths in the field of diamond thermodynamic stability. Variations in the redox conditions were noted. They manifested themselves as a wide range of fluctuations of the chemical composition of microcrystalline spinels, up to formation to Ti-magnetite and magnetite.
