Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.
中文题名燃煤微生物预处理浮选脱硫的试验研究副题名外文题名 Study on microbial pretreatment and floatation desulphurization in coal 论文作者周志付导师王英敏魏德洲教授学科专业安全技术及工程研究领域\研究方向学位级别博士学位授予单位东北大学学位授予日期2002 论文页码总数99页关键词燃煤微生物预处理-浮选脱硫煤炭脱硫馆藏号BSLW /2003 /X701 /2 矿物燃料是当今世界的主要能源,其中煤炭资源蕴藏量占总能源的75%以上,在煤的利用过程中,有害物质以各种方式排入周围环境,造成了严重的环境污染,因此脱硫已成为洁净煤技术的主要目标之一,而目前煤中硫的脱除存在的主要问题是:煤粉太细,脱硫时间长、技术复杂,投入费用太高等。

As far as animals'NISP is concerned, domestic animals occupy a very large proportion, while the proportion of wild animals doesn't exceed 25% all the time. Based on such statistics, it can be inferred that the manner by which ancient settlers of Erlitou site acquired their meal resources can be defined as"exploiting type".In the dietary contribution of this site four species, which are Sus scrofa domesticus, Ovis sp., Capra sp., Bos sp. and Cervus nippon, formed the most important and stable meal source of ancient settlers of Erlitou site. Meanwhile, Sus scrofa domesticus played the most important role among the four species.
本文可以确定狗、猪、山羊、绵羊和黄牛这五种动物为二里头遗址先民们饲养的家畜,它们的可鉴定标本数在全部动物可鉴定标本总数中占有非常高的比例,野生动物的比例始终没有超过25%,据此笔者认为二里头遗址先民们获取肉食资源的方式应属于&开发型&;从肉食结构来看,猪、牛、羊、梅花鹿这四种动物构成了当时二里头人最为重要而稳定的肉食来源,在这四种动物中,又以猪最为重要。

Objective:To produce low-sugar and high-moisture preserved pachyrhizus; Methods:The relationship of moisture and water activity, numbers of bacterial and mildew were researched. Then water activity was reduced by chitosans with different viscosity-average molecular weights; Results:The number of mildew was a major microbial index of quality-maintaining duration of product. The lower viscosity-average molecular weights of chitosans was, the more water activity reduced; Conclusion:When 9 kD molecular weight,...
目的:为生产低糖、高水分含量番薯果脯;方法:研究果脯中水分含量与水分活度的关系及细菌总数和霉菌数在保温试验中的变化,并采用不同黏均分子量的壳聚糖降低果脯的水分活度;结果:果脯中霉菌数是影响产品保质期的主要微生物指标,壳聚糖的黏均分子量越低,降低水分活度的幅度越大;结论:通过添加0.5%、9kD黏均分子量的壳聚糖,产品水分含量为20%、总糖为26%时,番薯果脯常温放置保值期达到12个月。
