新疆八一钢铁有限责任公司炼铁厂上料系统1^#转运站，1^#a转运站，2^#转运站及1^#、2^#高炉高道料仓在上料时，粉尘污染较为严重，为解决粉尘污染问题，1999年炼铁厂组织设计与施工了40m^2单室卧式3电场除尘器，工程投运后，收尘效果良好，岗位粉尘浓度与外排浓度均低于国家标准。     

自然灾害综合区划的基本类别及定量方法

依据区域灾害系统论原理,提出了以灾害强度、灾害势、抗灾力和灾度４个状态参量描述的区域自然灾害系统状态,建议以之为基础,将自然灾害综合区划分为灾害强度区划、灾害势区划、抗灾力区划和灾度我划４个基本类别、并结合自然灾害综合区划定量方法的讨论,以实例说明了上述基本类别类别划分的可行性。     

Scientist and policy-maker response types and times in suburban watersheds

Differences between scientist and policy-maker response types and times, or the “how” and “when” of action, constrain effective water resource management in suburbanizing watersheds. Policy-makers are often rushed to find a single policy that can be applied across an entire, homogeneous, geopolitical region, whereas scientists undertake multiyear research projects to appreciate the complex interactions occurring within heterogeneous catchments. As a result, watershed management is often practiced with science and policy out of synch. Meanwhile, development pressures in suburban watersheds create changes in the social and physical fabric and pose a moving target for science and policy. Recent and anticipated advances in the scientific understanding of urbanized catchment hydrology and pollutant transport suggest that management should become increasingly sensitive to spatial heterogeneities in watershed features, such as soil types, terrain slopes, and seasonal watertable profiles. Toward this end, policy-makers should encourage funding scientific research that characterizes the impacts of these watershed heterogeneities within a geopolitical zoning and development framework.

The centers of gravity and dynamic types of body shape of terrestrial invertebrates

In the framework of dynamic morphology theory, the centers of gravity and geometric centers of projections have been determined for the bodies of more than 182 forms of invertebrates, and these data have been used to distinguish four types of dynamic body shapes. It has been demonstrated that specific dynamic types of body shape are characteristic of individual taxa. In addition, there are a group of “transformers,” which may assume any dynamic type of shape, and a group of invertebrates with one predominant dynamic type.

基于井口涌水量变化类型判断岩溶含水层厚度

针对含水相对均匀的溶洞-裂隙水含水岩组,为判断岩溶含水层厚度,通过对空气潜孔锤钻进工艺施工钻孔井口涌水量变化进行分析,结果发现:利用该工艺施工的钻孔井口涌水量一般会出现稳定型、降低型和增长型三种变化类型;井口涌水量变化类型反映了岩溶含水层是空间尺度上发育的垂向地下水系统,具有分层特征,其厚度与碳酸盐岩岩溶化程度的不均一性耦合,体现了碳酸盐岩岩体内不同空隙的发育规模、密度及其相互间的联系程度;明确了地下水埋深状况以及含水层的构成条件。故采用空气潜孔锤钻进工艺施工的钻孔,在非干孔情形下,可以利用井口涌水量的变化类型判断岩溶含水层厚度。
