蜱类系统分类学研究已经进入分子阶段,与传统的形态学、生物学鉴定相比,无疑更加客观准确,建立系统进化树更能全面反映其亲缘关系,极大地提高了鉴定效率与可信度。论文总结了近年来应用分子生物学技术鉴定硬蜱的主要方法,包括核酸序列分析、随机扩增DNA多态性分析、限制性片段长度多态性分析。随着分子生物学和现代统计学的广泛应用,蜱类的鉴定将更加依赖现代分类学方法。

The parallel-hopper type bell-less top of blast furnace has the advantages over the serial-hopper type bell-less top in that it is easier to be used in production and more convenient for maintenance, while its top is much lower than that of serial-hopper type so that the construction investment can be reduced. Its disadvantage is that the circumferential burden-distribution is uneven. Therefore, the gas utilization ratio is reduced, which is not favorable for production. This paper dealt with how to overcome this disadvantage. It is found that owing to the tilt burden flow the burden locus on ...
