腐殖化的

The IR spectrum analysis results of the level of humification are consistent with those obtained from ultra-violet spectrum analysis.

其中，缙云山腐殖土腐殖酸的E465/E665最大，说明其分子的腐殖化程度、芳构化度和分子复杂程度等最小。

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。

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。

This indicates that these HA have similar compositions, but different structures and properties.Results from analysing E465/E665 are the same as those obtained by analysing molecule structure using colour index coefficientΔ~ K.Compassion study of HA in NaOH and NaHCO_3 solutions show that the absorption peaks shift towards the direction of longer wavelength.

这几个吸收带的变化证明了以紫色潮土HA、石灰性黄壤HA、中性紫色HA、酸性紫色HA、腐殖土HA为序的腐殖酸的芳构化度降低、缩合程度下降的观象，说明腐殖土HA其分子在苯环C骨架的聚合程度、芳构化度和分子复杂程度等上均最小，与紫外光谱分析结果一致。

The results suggest that the more humified humic acids, the more stability of the complication with metal irons.

说明腐殖酸的腐殖化程度越高，与金属离子形成络合物的稳定程度越大。

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。

Three types of humic acids, i.e. peat, lignite and weathering coal (named as C-HA, H-HA and F-HA, respectively), were extracted and stability constants of Mn(superscript 2+) and Zn(superscript 2+) with the three humic acids were investigated.

以分别来源于草碳、褐煤和风化煤的腐殖酸为供试材料，采用离子交换平衡法研究了不同腐殖化程度的腐殖酸与Mn(上标 2+)和Zn(上标 2+)的络合稳定常数，并探讨了环境pH值对络合稳定常数的影响。

The compost of agricultural waste materials is the process that under the function of microorganism, the organic matter turn into well-rotted manure by the way of the organic matter being mineralized and humus and harmless.

农业废弃物的堆腐是在微生物作用下，通过发酵使有机物矿质化、腐殖化和无害化而变成腐熟肥料的过程，在微生物分解有机物的过程中，不但生成大量可被植物吸收利用的有效态氮、磷、钾化合物，而且又合成新的高分子有机物---腐殖质。

农业废弃物的堆腐是在微生物作用下，通过发酵使有机物矿质化、腐殖化和无害化而变成腐熟肥料的过程，在微生物分解有机物的过程中，不但生成大量可被植物吸收利用的有效态氮、磷、钾化合物，而且又合成新的高分子有机物---腐殖质。由于这一过程是在微生物分泌酶的作用下酶促反应过程，研究酶活性变化可以从本质上揭示堆腐的生物行为。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
