淋溶作用

The evolution history of the volcanic rocks goes through five stages, the forming stage, the weathering and leaching stage, the burial and tectonic\|reforming stage, the erosion stage and the oil and gas accumulation stage. Finally, the model of porosity evolution was set up with andesite and basalt as examples.

在上述研究的基础上，将火山岩储集空间的演化过程分为火山岩的形成阶段、风化剥蚀淋滤阶段、埋藏和构造作用阶段、溶蚀改造作用阶段和油气聚集成藏阶段5个阶段，并以安山岩和玄武岩为例，建立了火山岩储层的孔隙演化模式。

DOC and HDOC in ridge, rice and rape use pattern in 0~30cm depth layer much more than other treatments after 14 years and showed significant differences;land use of rotation of waterlog rice and dry rape which was disadvantageous to increase the quantity of DOC, which indicated DOC is good evaluation index of soil quality land use effect for paddy soil.

土壤有机质损失的重要途径主要是DOC的淋失，土壤可溶性有机碳是土壤有机碳周转的必要环节，是其中的不稳定组分，主要包括有机残体的可溶性有机物、土壤微生物分解有机残体后未吸收的可溶性有机物及微生物细胞衰老自溶后释放的可溶性有机物[4]，在陆地生态系统碳循环中起着重要作用[5]，所以DOC的分析

The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

综合各国学者的有关研究资料，建议将白垩状结构化定义为：&碳酸盐沉积物和碳酸盐岩中的镁方解石和文石在不同成岩阶段通过新生变形而转变成低镁方解石微晶和微亮晶格架，并在其中产生和保存晶间孔喉网络的作用；强化白垩状结构化是指微晶和微亮晶格架受到进一步溶蚀和淋滤，从而形成次生溶蚀孔隙网络的作用&。

Introduce of actual acidification velocity(H~+ produced) for evaluating the acidifying effects of soil tested,only the stimulated acid rain with pH2.5 could lead to soil acidifying,however,acid rains with pH≥3.5 played a buffering role to soils tested,with the weakening of soil acidity.

引进土壤的实际酸化速率H产生+值衡量供试土壤的酸化，只有pH2.5的模拟酸雨淋溶促进了土壤的酸化，而pH≥3.5的模拟酸雨处理对土壤的酸化具有一定的缓冲作用，且土壤酸度减弱。

Soil erosion is the process of that soil particles with surface attachments are moved, transferred and deposited under external forces, such as water power, gravity and wind power, physical, chemical weathering and eluviations, including human beings activities.

土壤侵蚀是指在外营力作用下，土壤颗粒及地表附属物被剥蚀搬运、迁移、沉积的一个过程，侵蚀的源动力来自于水力、重力、风力、物理或者化学风化、淋溶过程，人为活动也是一个重要的源动力。

With the action of leaching by rain and water and self-combustion , some hazardous trace elements and harmful organic materials will be dissolved completely or partly and move out from coal mining waster into water, soil and gas.

大量的煤矸石在雨水和地表水的淋溶以及自燃等自然条件作用下，一些有害微量元素能够溶解、挥发出来进入水体、土壤环境和大气环境，从而造成水体质量下降、土壤功能被破坏、大气污染，并由此对生态发展和人体健康有严重的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
