In addition, there was an activity evaluation on TiOa thin film using HA as handle objects. The results showed that TiO2 thin film had a good effect on degradation of HA, and the degradation rate could attain to 52.9% in three hours which was 18.2% higher than that of direct photolysis, but when compared to the TiO2 aqueous suspensions, the degradation rate of TiOa thin film was a little lower.
并以腐殖酸为处理对象,对TiO_2膜进行了活性评价,发现该固定TiO_2膜光催化体系对降解腐殖酸有良好的效果,反应3h,腐殖酸的降解率达52.9%,比直接光解法降解腐殖酸的效率提高了18.2%,但与悬浮态TiO_2光催化氧化系统相比,其降解效率略有降低。

These humic small molecules are probably the humified products of various compounds in different humification procession. Their composition and amount will be different in different environment. This indicated the complex composition of the humic acid-like geomacromolecules and the various effect in the environment.
这些具有不同性质的腐殖酸小分子可能与腐殖酸形成过程中不同母质来源物质在不同阶段的腐殖化产物有关,并且不同环境中的腐殖酸分子由于其地质条件的差异,所含腐殖酸小分子的组成和数量都不会完全相同,表明腐殖酸类地质大分子物质结构组成的复杂性和在环境中影响的多样性。

The decrease of total humic acid, free-form humic acid and water soluble humic acid of compost after composting, and the increase of the ratio of humic acid to organic carbon proved obvious trend of carbon humification in the compost course.
腐熟后的堆肥总腐殖酸、游离腐殖酸及水溶性腐殖酸呈下降趋势,但腐殖酸与有机碳的比率增高,说明堆肥过程中碳素腐殖化作用明显。

Soil-feeding termites and humus-feeding scarabaeid beetle larvae can selectively mineralize and degrade the peptidic component of humic acids in soil through combined functions of special proteolytic activities and extreme alkalinity (pH 10-12.5) of gut compartments in their intestinal tracts, and, as a result, enhance the humification of the humic acids.
食土白蚁和甲虫幼虫的极端碱性(pH10~12.5)肠道段和肠道内的特殊蛋白酶的共同作用促使这两种动物可以选择性地降解和矿化腐殖酸中的稳态多肽等组分,进一步提高腐殖酸的腐殖化程度。
-
This is exactly opposite to the order of E465/E665 in HA and the order ofΔ~ K. It shows that the larger the extent of humification, the larger the effect for reducing the rate of Phoxim hydrolysis, because the extent of HA humification is closely related to the extent of benzene in HA and the amount of carbonyl, aryl, phenolic hydroxide.
因腐殖酸腐殖化程度与腐殖酸芳构化程度、羧基、羰基和酚羟基的含量等相关,因此用腐殖酸腐殖化程度反映腐殖酸对农药水解作用大小比仅用腐殖酸中有机碳含量等因素反映更为合理。
-
A mixture of different races.Of, relating to, or derived from humus.
腐殖的腐殖的,与腐殖有关的,从腐殖中提取的
-
Of,relating to,or derived from humus.
腐殖的腐殖的,与腐殖有关的,从腐殖中提取的

Recent-year studies demonstrate that wax consists of not only high-molecular-weight normal alkane, hut also isoalkane, naphthene and olefin; and the origin of wax is not only from high plant, but also lower hydrobiont and lacustrine algae which are as important contributors to the wax.
并认为蜡不仅仅源于高等植物,低等水生生物和湖相藻类对蜡也是重要贡献者。南阳凹陷原油含蜡量高达40%~60%,烃源岩有机质以偏腐殖的混合型为主。
-
The results of this work indicate that the humic macromolecule is composed of many humic molecules with different relative molecular mass and chemical compositions. These humic mo lecules are probably the humified products of various compounds in different hum ification processes. This implies the heterogeneous and complex compositions of the humic acid geomacromolecules.
本研究结果不仅说明环境中的腐殖酸分子是由许多相对分子质量不同、结构性质各异的腐殖酸分子组成,而且这些腐殖酸分子可能与腐殖酸形成过程中各种来源的物质在不同阶段的腐殖化产物有关,表明了腐殖酸类地质大分子物质的非均一性和复杂性。
