呼伦贝尔市2010年气候对牧业影响分析

利用牧区6个台站1961～2010年降水、气温、日照时数、大风日数等气象资料,采用统计学方法对呼伦贝尔市2010年主要气象要素与50年系统观测的气象资料进行对比分析,并结合牲畜生理特征及牧草生长特,4,分析2010年呼伦贝尔市气候异常特征,研究气象条件与牧业的关系.结果表明,2010年呼伦贝尔市冬春异常低温,夏季干旱是制约该市2010年牧业产值的主要气象因素;并提出要加强畜牧业基础设施建设,发展草原水利工程,提高防灾减灾能力,适应气候变化,提高产品质量,最终达到现代畜牧业的发展要求.     

Progress in Research on Vanadate-Based Coatings on Corrosion Resistance

Vanadate, usually used as the corrosion resistant inhibitor for the paint systems, is one of the substances that have been proposed as alternative to toxic chromate for the corrosion protection. In this paper, the possibility of vanadate passivating from its chemical properties was introduced firstly. Then, the progress and examples in research on vanadate conversion coatings on the corrosion resistance were summarized. And the substrates discussed here contained aluminum alloys, magnesium alloys and so on. Finally, the research tendency of vanadate-based coatings was discussed.     

从金属镁厂热平衡来看硅热法炼镁节能方向

本文以硅热法金属镁厂生产过程热平衡为基础,分别分析白云石煅烧以及真空热还原的能量收支情况,并对其效率进行评价。通过对比金属镁生产理论能耗和实际能耗,结果显示该工艺下能量利用效率偏低,进而讨论金属镁厂节能减排的方向,包括减少烟气排放热损、减小散热损失及还原渣的余热综合利用。并提出了硅热法炼镁的具体节能措施。     

论企业营销信息的收集和应用

要管理好一个企业必须管理他的未来，而管理未来就是管理信息。文章通过对信息进行分类，分析了企业所需要的营销环境、产品规划、市场分布、产品价格等四类市场信息，提出了直接获取、销售人员定期报告、分销商报告、通过外界情报供应商获取和职能人员摘录等五种获取市场信息的方式。同时，对企业应该如何建立自己的信息链，从而保障市场信息在企业的有效传递进行了阐述。

Present findings on rotaviruses with emphasis on rotaviruses in swine

A summary of thirty pages, concerning rotaviruses, i.e. RNA-viruses, the most frequent causal agents of infectious diarrhoea in children and young farm animals. Most of the chapters are generally focused on rotavirus morphology, structure and biology. Chapter No. 6 is especially detailed, trying to offer a complete summary of available diagnostic methods. The final chapters concern in greater detail the problems of rotaviruses in pigs, such as the immunity, prevention and treatment.     

Cytogenetic effects on lymphocytes in osteoporotic patients on long-term fluoride therapy

The genotoxicity of fluoride in vivo in seven patients with osteoporosis was cytogenetically investigated. The patients were treated with fluoride-containing formulations (disodium monofluorophosphate and sodium fluoride) for a period of 15 months up to 49 months. Fluoride intake ranged from 22.6-33.9 mg F/day and serum fluoride concentrations were between 0.1 mg F/l and 0.2 mg F/l. Peripheral blood lymphocytes of these patients were cultured in vitro and examined for chromosomal aberrations, micronuclei in cytokinesis-blocked binucleated lymphocytes as well as cell cycle progression. When a comparison was made between patients' group and a matched control group, it was found that fluoride at the tested concentrations had no detectable genotoxic potential in human.

钢中添加元素对酸洗速度影响的研究

工业酸洗过程中,经常会发生欠酸洗和过酸洗现象,过酸洗会加大酸耗和铁损,影响经济效益;而欠酸洗降低润湿性,影响表面质量,所以速度对于酸洗来说,是一个很重要的因素。文章就钢中元素(C、Mn、P、S和Si)对腐蚀速度的影响作了系统的研究,用失重法测出不同钢种腐蚀速度,并做出元素对腐蚀速度的影响趋势图,对于指导实际生产有一定的参考价值。
