科技期刊编辑应具备的基本素质

对科技期刊质量和编辑素质的关系进行了研究，认为编辑是期刊的设计师。一本期刊从总体创意、策划选题、编审稿件到排版设计，无不体现编辑的主体意识。期刊质量的好坏，读者评价的高低都与编辑息息相关。编辑的素质关系到期刊的生存和发展。得出不断提高科技期刊编辑的素质是十分必要的结论。     

盐渍土与分散性针孔试验影响

通过具体实例,研究了新疆氯盐渍、硫酸盐渍土对针孔试验的影响,认为氯盐渍土因其胶结作用,随着盐量的增加,土样孔径大小、流量变化不大。硫酸盐渍土因其膨胀性,随着盐量的增加,土样孔径、流量减小,对土样的冲蚀破坏作用而不相同。     

地震前兆观测仪器标定问题的探讨

标定工作，在地震前兆观测仪器的研究，使用及所得数据的处理中均已成为一个不可少的环节，但缺少有关标定问题的基石性研究和讨论。本文就标定的定义、种类、目的、要求、存在的问题等做一粗线的讨论，以期今后加强这一工作的深入研究。     

1995年苍山5.2级地震前应力场的动态变化

从１９９５年９月２０日山东苍山５．２级地震前源区及其附近不同小区应力场方向的动态变化入手，分析了主应力轴方位、仰角及其矛盾符号比等参量在５．２级地震前的异常变化及其时空演变特点，简析了可能成因，可为研究震前其它各类前兆异常提供背景依据     

中国东北区古生代生物地层学几个问题

作者对东北区古生代地层中，几个人们关注的生物地层学问题，诸如麻山动物群、清河镇动物群等，作了比较客观的评价，可供今后的研究工作参考。     

Coal-generated oil in Tuha Basin

The Turpan-Harmi (abbreviated to Tuha below) Basin is a typical basin of coal-generated oil accumulation in China. The Middle-Lower Jurassic coal measures are considered the main source beds. Hence, both desmocollinite and suberinite are considered the contributors for coal-generated oil. Principal geochemical features of the crude oil in the Tuha Basin are rich in alkanes (70%—80%), high pristane/phytane ratio (6—8), abundant heavy carbon isotope (δ¹³C PDB= -26%–-23%) and absolute GP sterane predominance. The hydrocarbon generation process from the coal series is characterized by multistages, early generation and early expulsion.     

邯郸市西部岩溶地下水的利用与开发

根据区域内岩溶地下水供需水现状，特别是通过对岩溶地下水最新开采动态资料分析，认为邯郸市西部岩溶水区尚具有一定的开发潜力，并提出了解决岩溶山区(革命老区)人畜用水的可行性和拦蓄滞洪、人工补给的有效途径，为地方经济持续发展提供决策依据，也可为北方类似岩溶地区所借鉴。     

中国兴凯湖北岸平原晚全新世花粉记录及泥炭沼泽形成

通过兴凯湖北岸平原泥炭剖面高分辩率花粉分析研究，对晚全新世花粉划分4个组合带。XKH-4组合时期(1857～1746aB．P．)为沼泽发育前期，这一时期花粉浓度小，陆生草本植物占优势，气候干冷。XKH-3组合时期(1746～1287aB．P．)为沼泽发育早期，这一时期花粉浓度较大，且水生植物花粉含量为剖面最高，喜温落叶阔叶植物大发展时期，气候温和湿润。XKH-2组合时期(1287～602aB．P．)为沼泽发育中期，这一时期花粉浓度最小，但以陆生草本植物为主，木本植物为辅，水生植物急剧减少，针叶植物出现两次高峰，气候向冷干方向发展。XKH-1组合时期(602aB．P．至今)为沼泽发育盛期，这一时期花粉浓度最大，陆生草本植物大发展时期，气候波动较大。     

Multi-dimensional Seismic Response Analysis of Base-Isolated Frame Structure with 3D Isolator

INTRODUCTIONAs a new and effective method for withstandingthe horizontal component of earthquake motion on abuilding structure, the base isolation technique hascome to the engineering application phase ( Hu,1988). However, for some important buildings andfoundation facilities in an earthquake region, it is im portant to consider the effects of 3D aseismatic analy sis, including the vertical component, due to themulti dimensional characteristics of earthquakes (Suand …     

Optical system research of multi-object fiber spectroscopic survey telescope

In the first part of this paper,four different Cassegrain optical systems with their correctors are designed and studied for multi-object fiber slit spectroscopic survey.The aperture in 6.5 m and field of view 3°are taken for these optical systems.Assuming observation wavelength range is 0.365–0.95μm,the maximum zenith distance for observing is 60°,the maximum diameter of these lenses is 1.66 m,the altitude of the telescope site is 2500 m,two correctors are composed of 4-piece lenses and the other two are 5-piece lenses.The results obtained are:f-ratio about 3.7,the image quality for all four systems with EE80D≤0.60′′,the linear diameter of the focal surface is about 1.2 m and 11 000 fibers can be set on it.Considering the limit of size of fused silica and optical glass,the maximum diameter for lens is about 1.7 m.Such a 6.5 m telescope is about the largest one if using the above correctors.Considering the multiobject spectroscopic survey is greatly important,we also studied some telescope optical systems having their aperture near or larger than 10 m used for the multi-object fiber spectroscopic survey.Such ideas are introduced in the last section of this paper.
