医用历四柱干支显现的基本规律

本文依据天文万年历研究了医用历四柱干支显现的基本规律：（１）共有５１８４００种四柱干支组；历经一个６０甲子年显现的一半；历经２个６０甲子年显现的３／４；历经３个６０了年大多数显现；历经４个６０甲子年才全部显现。（２）四柱干支历经４个６０甲子年基本重现，医用历轮回周期的２４０年。     

复合式防水板在隧道防排水施工中的应用

随着我国既有线铁路大面积提速改造及快速铁路、高速铁路的修建,一些新技术、新材料、新工艺时于隧道工程的设计理论和施工技术带来了新的挑战,同时在许多方面深化和改革了传统的设计思路和施工方法.目前运营铁路中,隧道渗漏水已逐渐成为危及铁路行车安全的一大病害,隧道防排水工作已越来越受到建设、设计、施工、运营等单位的高度最视.文章着重介绍了隧道防排水施工中复合式防水板的应用及施工注意事项.     

碱提法回收猪骨蛋白质的探讨

对碱提法回收猪骨蛋白质工艺参数的研究表明，4种工艺参数对蛋白质得率均有不同程度的影响。其顺序为浸提液pH＞浸提时间＞沉降pH＞浸提温度。碱提法回收猪骨蛋白质的最高得率为25．7％，最佳工艺参数为浸提时间105min，浸提液pH12．0，浸提温度30℃和沉降pH5．0。     

壮族中小学生身体形态和机能发育状况分析

对１９８５－１９９５年广西７－１８岁城乡男女壮族学生身体形态，机能的动态分析结果表明：形态生长发育水平有了较大提高体格发育速度较快；肺活量水平有所提高；身体发育的匀称度有一定改善。在生长发育状况上城乡存在着明显差异。主要形态指标身高，体重和胸围每１０年平均增长值多数明显落后于全国同期水平，使原有的差距再拉大。

An initial discussion on major controlling factors on formation of coal-formed large-medium gas fields

The so-called "large-medium gas field" means a gas field with proven reserves equal to or larger than 100×108 m3.Up to 1997,23 coal-formed great-medium fields are discovered in China,excluding two in Taiwan Province.Their proven reserves take 50.9% in total natural gas reserves.Therefore,the coal-formed great-medium gas field plays a decisive role in natural gas reserves and the study of their controlling factors is very important both in theory and in practice.There are six major controlling factors on the formation of coal-formed large-medium gas fields:(ⅰ) The generating center of coal-formed gas and its surrounding area; (ⅱ) low potential area; (ⅲ) late pool-forming period; (ⅳ) traps related to the paleo-uplifits in coal-formed gas area; (ⅴ) above or between abnormally pressured compartments; (ⅵ) faulted traps related to coal-bed.     

Formation and biocorrosion behavior of Zr-Al-Co-Nb bulk metallic glasses

Ni-and Cu-free Zr-Al-Co-Nb glassy alloys with different Nb and Co contents were synthesized by melt spinning and copper mold casting.The effects of Nb addition to partially replace Co in the Zr55Al20Co25 glassy alloy on the glass-forming ability,thermal properties,in-vitro biocorrosion behavior and surface wettability of the metallic glasses were investigated.Although addition of Nb up to 5 at.% slightly decreased the supercooled liquid region and the glass-forming ability(GFA),the alloys could be casted in a bulk glassy rod form with diameters up to 3mm.The Zr-Al-Co-Nb glassy alloys were spontaneously passivated with low passive current densities in phosphate buffered saline and Hanks’ solution.Substitution of "toxic" Co by Nb is effective in improved the corrosion resistance of the Zr-Al-Co glassy alloy.Water contact angle measurements showed that Nb addition increased the hydrophilicity of the glassy alloys,which may enhance cell adhesion of the alloys in biomedical applications.     

煤巷围岩稳定性综合分类及锚杆支护形式合理选择

提出一种围岩稳定性综合分类法，用此法研究平顶山矿区煤巷稳定性变化规律，得到了综合评价围岩稳定性的统计判据，可根据巷道条件及实测信息评价巷道稳定程度，并绘制出多指标围岩分类图。文中相应阐述了煤巷锚杆支护形式选择原则。     

天然放射性示踪剂的应用——Ⅵ.用三种示踪剂研究九龙江泥沙对厦门航道的影响

本文利用~(210)Pb,~(226)Ra和总β放射性示踪剂,研究九龙江入海泥沙对厦门西港航道淤积的影响,九龙江入海泥沙的大部分是沿着九龙江的主流方向输入外海,只有一小部分进入厦门西港。而且进入西港的九龙江泥沙,只对西港的西航道(即嵩鼓海峡)产生一些淤积作用,对西港的东航道(即厦鼓海峡)看不出有明显影响。这一结果和我所地质室用地貌方法所得的结论相吻合。
