借助爆炸动力学理论讨论了隐爆作用的机制,提出隐爆作用的本质是因超压导致相变而发生的一种快速物理反应;而岩浆上侵至低围压的中浅层环境→气水组分分离并产生气泡→后续岩浆提供高压力梯度导致超压,即为隐爆作用得以发生的主要条件。

The results of the present research are as follows, The correlation between physico-chemical properties of organic compounds and their competitive power was studied, and it was indicated that organic compounds preferable to form H-bonding with organic matter of sorbents have stronger competitive power; Sorption behaviors of ionizable organic compounds in different species and their competitive power were examined, and the results showed that phenols and carbonxylic acids with benzyl circle have much stronger competitive power in molecular species than in ionized species, because negative charges of anionic forms can depressed their adsorption on the surface of the sediment; in contrast, organic bases such as aniline and p-chloroaniline show weaker competitive power in molecular species than in ionized species, and this is because both species of the organic bases could adsorb strongly onto the sediment; there is a correlation between competitive power of organic pollutants in multi-solute systems and their sorption isotherm nonlinearity in single-solute systems, and organic compounds whose sorption isotherms is linear in single-solute systems hardly have competitive power in multi-solute systems; Competitive sorption effects in more than two-solutes systems was studied, and it was exhibited that mixture of two cosolutes each of which could suppress sorption of nominal solute onto the sediment had synergistically competitive sorption effect on the nominal solute; A method about incorporating sorption/desorption of organic pollutants into river water quality model was developed, and discussion about degree of sorption/desorption effect on model prediction for different organic compounds was made, which will provide theoretical basis and practical processes for setting up more accurate water quality model.
论文主要取得了以下研究成果。(1)有机化合物的吸附竞争能力与其物化性质具有相关性,易与沉积物有机质形成氢键的化合物其竞争能力也比较强;(2)可离子化有机化合物的吸附竞争能力与其存在形态有关。酚类、含苯环的羧酸类化合物,其离子态的吸附竞争能力远小于分子态,其机理为有机酸阴离子所带的负电荷抑制了表面吸附能力,主要发生分配作用;而苯胺类化合物,其离子态和分子态都表现出显著的竞争能力,而且离子态的竞争能力略强于分子态,原因在于有机碱阳离子所带的正电荷促进了其表面吸附能力;有机化合物竞争能力的强弱与其单组分吸附等温线的非线性程度具有一定的相关性,吸附等温线近似为线性的化合物没有或只具有微弱的竞争能力;(3)对目标有机化合物的吸附具有竞争效应的有机化合物混合后,将对目标有机化合物的吸附产生协同竞争效应;(4)以京杭运河为例,率先提出了将有机污染物的吸附/脱附作用及水文水力参数耦合到水质模型中的方法,并讨论了吸附/脱附作用对不同有机污染物预测模型的影响,为建立更准确的水质模型及进行更客观的风险和生态评估提供了参考依据。

Phenylmethylsulfonyl fluoride (174.2 mg/mL), chicken ovomucoid (1000 mg/mL) and soy-bean trypsin inhibitor (1000 mg/mL) could inhibit enzyme activity, which indicated that the enzyme belonged to serine protease group. On plasminogen-free fibrin plates and plasminogen fibrin plates, the fibrinolytic activity had no obvious difference, indicating that the enzyme was a fibrinolytic enzyme which degraded fibrin directly, but not a plasminogen activator which degraded fibrin by activating plasminogen.

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.
