A study on the orbit of air temperature movement

In this paper, we describe an air temperature movement by mapping its time series to the polar coordinates: the value of the time series is plotted on the radial coordinate and the time on the angular coordinate. In this way, both the yearly and daily air temperature movements from five different locations of China are used to demonstrate that, in an intuitionistic view, air temperature movement is neither random nor chaotic, but has its own orbit. We then propose an elliptic orbit model for the air temperature movement. Our proposed model provides quite good results when it is applied to the evaluation of yearly air temperature movements in eight locations in various parts of the world, and the evaluation of daily air temperature movements in five locations in Hunan Province of China on December 17, 2005. Results show that our approach provides a concise and helpful model for air temperature analysis.

Pearce型构造岩浆地球化学判别图评述——以玄武岩为例

自从六十年代板块构造的概念诞生以来,人们认识到有必要探讨古地理和古构造重建的方法.一段时期以来,很多学者(如Gilluly,1971)认为,岩浆作用与特定的大地构造环境紧密相关,不同的岩浆类型或火山岩系列产在一定的地壳环境,因而出现了许多运用主要或微量元素资料的分类体系或判别图.基于Irvine和Barager(1971)以及Miyashiro(1973)发表的主要元素图解能用来判别岩浆类型,而Pearce(1976)则介绍     

高温嗜粪菌的选育和猪粪发酵研究

筛选得到了８株嗜高温（５５℃）嗜粪细菌，均具有较强的发酵猪粪能力。加入所选育菌株进行的猪粪高温（５５℃）固体好氧发酵实验发明，２４ｈ内可将猪粪发酵成无臭味、深褐色的稳定和无害化产物，常温下长时间放置也不会产生腐败和臭味。此发酵产物的氮试验法结果显示，猪粪已发酵至表观成熟和稳定化，可作为进一步制取优质有机复合肥料的良好前体物。     

中国东南沿海大(中)型浅成中低温热液矿床—斑岩型矿床评价的地质准则、成矿模式及其找矿意义

本文总结中国东南沿海高钾钙碱性—双峰式火山岩带中已勘查大中型矿床成矿环境的共性：矿床所处区域构造的部位、成岩与成矿时代、矿床与岩浆成因类型、火山构造及其基底构造控矿性、矿床与爆发角砾岩、矿床与矿化类型叠加与共生、矿化与蚀变的分带往、矿床定位深度与剥蚀深度。作者认为这八点可作为找寻与评价大（中）型矿床的地质准则。通过火山地质与矿床地质统一的研究提出本区晚中生代以火山为中心地热体系的成矿模式。并就三个方面作类比：①与现代火山地热体系成矿作用类比；②以紫金山高硫型浅成低温热液矿床与世界同类型矿床作比较；③与环太平洋其他火山岩带同类型矿床模式作类比．通过建立本区的模式与类比获得进一步找矿中值得重视的一些思路．     

LPWCO method for the treatment of high concentrated organic wastewater

Based on wet air oxidation (WAO) and Fenton reagent, thispaper raises a new low pressure wet catalytic oxidation(LPWCO)which requires low pressure for the treatment of highlyconcentrated and refractory organic wastewater. Compared withgeneral wet air oxidation, the pressure of the treatment(0.1-0.6MPa) is only one of tens to percentage of latter(3.5-10MPa). Inaddition, its temperature is no more than 180℃.Compared withFenton reagent, while H2O2/COD(weight ratio) less than 1.2, theremoval of COD in the treatment is over twenty percents more thanFenton's even the value of COD is more than 14000mg/L. In thispaper, we study the effect factor of COD removal and the mechanismof this treatment. The existence of synergistic effect (catalytic oxidation and carbonization) for COD removal in H2SO4-Fenton reagent system under the condition of applied pressure and heating (0.1-0.6MPa, 104-165℃) was verified. The best condition of this disposal are as follows:H2O2/COD(weight ratio)=0.2-1.0, Fe2+ 0.6×10-3 mol, H2SO4 0.5mol, COD>1×104mg/L, the operating pressure is 0.1-0.6MPa and temperature is 104-165℃. This method suit to dispose the high-concentrated refractory wastewater, especially to the wastewater containing H2SO produced in the manufacture of pesticide, dyestuff and petrochemical works.
