Horticola , in which Compositae, Cruciferae, Laguminosae and Cucurbitaceae are the main families. It occurs seriously on lettuce, cauliflower, pea, rape and horsebean. The hosts can be divided into four types: the most fitting host, fitting host, preferable host and secondary host. The oviposition of C. horticola on 8 kinds of hosts selected was checked under microscope, which had proved the investigation of host suitability and lettuce is the favorite host.

Therefore, the aim of these treatments is to provide a mature, stabilized organic material in which the humification process,Which typically occurs under natural soil conditions, has started and has reached an adequate degree with the production of "real" humic substances.

因此，这些处理的目的就是要提供一个成熟的稳定的有机物质，在其中腐殖化作用（自然土壤条件下的典型现象）已经发生而且已经达到一个足够的程度，能产生真正的腐殖质。

Scoyenia ichnofacies widely occurs in flood plains and the transitional belts of rivers and lakes, Termitichnus ichnofacies owns features of continental environment, Rusophycus ichnofacies made its appearance in river channel and levee sub-environments of relative high energy, Arenicolites ichnofacies colonized on the surface of hummocky sandstones of storm deposits.

Scoyenia遗迹相广泛发育在洪泛平原、冲积平原以及河流与湖泊的过渡地带，Termitichnus遗迹相是陆地沉积环境的特征，Rusophycus遗迹相出现在河流沉积环境河道、堤岸等能量较高的亚环境。Arenicolites遗迹相在开阔湖风暴沉积的丘状砂岩层面上拓殖，主要由机会分子构成。

Dissolved oxygen in water is important to maintain sea ecosystem, and "organism hungriness" will appear in some sea area if hypoxia occurs in estuaries. It is very harmful to ecosystem, organism resource, economy development and human health.

In this paper, initiator is dissolved in 1-bromopropane which is solvent. Then the propene and hydrogen bromide that can be dissolved in 1-bromopropane are inlet in l-bromopropane when initiator is decomposing. The reaction occurs in fluid phase and high-purity 1-bromopropane is synthesized by one step method. In this paper, the material HBr is synthesized with NaBr and sulfuric acid at the presence of hydrobromic acid.

本论文以1-溴丙烷为溶剂，将引发剂溶于其中，加热到引发剂开始分解时再通入丙烯和HBr，使二者溶解于1-溴丙烷中，在液相中进行反应，实现丙烯"一步法"合成高纯1-溴丙烷利用NaBr与硫酸在氢溴酸存在下反应制备HBr气体，以作为合成1-溴丙烷的原料。
