查询词典 soil

Due to the non-selective characteristics of oxidants, three aspects concerned for estimating ISCO oxidant dosage requirement for effective treatment of target contaminants must be considered: the stoichiometric amount of oxidant for destroying the contaminant, the oxidant demand to meet with the consumption by natural soil oxidizable matters and the amount resulting from oxidant self-decomposition. It should be noted that the oxidant consumed by the background organic and inorganic components of the soil aquifer matrix is known as soil oxidant demand of the treatment zone.

由於大多数氧化剂不具选择性，因此若欲使目标污染物达到良好的降解效率，必须考量目标污染物所需之氧化剂剂量、氧化剂本身自我降解量，以及与土壤中其他可氧化物质（oxidizable matter，OM）反应之消耗量，此三者综合才是真正现地应用所需之氧化剂总量，而用以克服土壤中非目标OM之氧化剂量称为土壤氧化剂需求量（soil oxidant demand，SOD）。

The degradation of PAHs at 0.03, 0.3, and 3 mg/g soil, either added singly or as mixtures, were evaluated for their evolved CO2 in Biometer flasks. The contaminated soil was later Soxhlet extracted with hexane. The extracts were evaporated, redissolved in dimethyl sulfoxide, and subjected for Microtox assay and Medaka embryo toxicity test. The evolved CO2 from singly PAHs addition was correlated with concentration gradient.

根据结果显示，受单一PAHs污染土壤之降解量，以CO2累积量表示，两环之Naphthalene其降解量为最多，在低浓度0.03 mg PAHs/g soil时，有所谓的诱引作用产生；受混合PAHs污染土壤之降解量，以Naphthalene对於Phenanthrene的刺激作用为最大；在复育实验方面，以添加苯酸之CO2累积量为最高，单就界面活性剂而言，则以Tween 80的表现为最佳。

The soil nutrient is detected in five shrub trees, namely Periploca sepium, Sophora davidii, Syringa pekinensis, Ostryopsis davidiana, Caragana intermedia and comparative Bothriochloa ischaemum community. We have evaluated comprehensively on soil nutrient index during the process of shrub community form and analyzed the linear correlation of soil nutrient factors.

In an article first published in Foreign Affairs in 1993 and then expanded into a book, Huntington foresaw the shape of the post Cold War world. The war of ideologies would yield to a civilizational struggle of soil and blood. It would be the West versus the eight civilizations dividing the rest—Latin American, African, Islamic, Sinic, Hindu, Orthodox, Buddhist, and Japanese.

最初发表在1993年&外交事务&杂志上的一篇文章就是《文明的冲突》的雏形，而在那篇文章中亨廷顿已经预见到了后冷战时代的世界格局，意识形态的战争将导致一场&鲜血与祖国&（blood and soil，曾经的纳粹口号）的文明冲突，那将是西方世界与余下的其他8个文明的对抗----拉丁美洲、非洲、伊斯兰国家、中华、印度、东正教、佛教和日本。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。
