西山白家庄矿8煤可排放硫含量的测定

针对西山白家庄矿8煤的实际情况，初步尝试了测定其硫的实际排放状况，探索了温度及添加剂对可排放 硫含量的影响。结果表明该煤的自身固硫率不高； 添加9％的CaO可排放硫含量可以达到城市窑（锅）炉对硫分的要求；同时试验表明MgO对可排放硫影响不大。     

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

An approach to the fluctuation mechanism of ecotone

In this paper,the relationship among land productivity,population pressure and the fluctuation mechanism of ecotone is analyzed,taking coumties and banners of southeast Inner Mongolia plateau as an example,which is the most fragile part in the farming and husbandry interleaving belt of north China due to its severe desertification degree and low level of economic development.The Cv for the total output value of agriculture decreases from southeast to northwest,with the same rule as which the overloading population cumulated distributes,and both indicators have close relation with the high linear coefficient of 0.83.These reveal the fluctuation mechanism for ecotone:fluctuation of the level of economic development is a scientific and practical measure both to weakness degree and to instability of ecotone,because it is a synthesized response to the variation of climate as well as irrational land uses,which reinforce and magnify the fluctuation.In detail,the heavier the population overloading,the severer the grassland reclamation,the stronger the dependence of regional productivity on rainfall,the lower the level of economic development,the rougher the fluctuation of ecotone,but the weaker the PRED system.

中国火葬场二噁英类污染物排放及减排技术研究

对中国某火葬场9具遗体进行了二(口恶)英类污染物排放测试,测试结果表明,烟气中二(口恶)英类物质总浓度为89～350ng·m-3,毒性当量浓度为1.5～5.4ng·m-3;PCDFs的总浓度高于PCDDs的总浓度;以此估算中国2004年火化遗体过程中二(口恶)英类污染物的年排放量为11.2～46.9 g·a-1.通过实验分别研究了布袋除尘器、布袋除尘器加不同厚度的活性炭纤维毡组合对火化遗体烟气中二(口恶)英类污染物的去除效果.结果表明,布袋除尘器去除火化烟气中二(口恶)英类污染物的效率为57.4%;布袋除尘器分别与厚度为5、15mm的活性炭纤维毡组合去除火化烟气中二(口恶)英类污染物的效率分别为64.0%和89.2%.     

中国PM_(2.5)污染状况和污染特征的研究

近１０ 余年来在中国的城市地区和清洁地区进行了ＰＭ２－５ 的采集和分析，其中包括ＰＭ２－５ 的质量浓度、离子和元素成分、酸度和酸化缓冲能力以及来源解析，研究结果表明，中国大部分地区ＰＭ２－５ 的污染较重，不论是质量浓度，还是各种主要成分浓度，在ＴＳＰ 和ＰＭ１０ 中都占有很高的比重，而ＰＭ２－５ 的酸度也远远高于ＴＳＰ 和ＰＭ１０ ，特别是近年来ＰＭ２－５ 污染还有相对加剧的趋势。

南京东郊石炭纪威宁期的风暴沉积

南京东郊石炭纪威宁期碳酸盐岩地层中普遍见有风暴沉积,以有突变的底界和底面构造、贝壳层、粒序层以及在风暴低能快速堆积条件下所形成的遮蔽构造等为基本鉴别要素,这些要素的不同组合构成的剖面结构可划分为五种类型,据此笔者提出本区风暴沉积的综合剖面结构。     

黄河口及邻近海域溶解态无机磷、有机磷、总磷的分布研究

于2003年8月下旬对黄河口及邻近海域进行了十船连续同步27h采样调查,分析了调查区域的溶解态无机磷、有机磷、总磷的平面分布、断面分布、时间分布特征.结果表明,在调查区域内,溶解态无机磷浓度很低,而溶解态有机磷浓度较高(占溶解态总磷的85%以上),是溶解态总磷的主要组成部分.各形态磷的平面分布、断面分布均呈现出由河口向邻近海域降低的趋势,溶解态总磷、溶解态有机磷梯度变化较溶解态无机磷更为明显;潮汐对河口浅水区的各形态磷浓度影响较大,对邻近调查海域的影响不明显.
