查询词典 fraction of coverage

5The leachate recirculation promoted the speciation of Cu and Zn shift fromunsteady fractions (acid soluble fraction and reducible fraction) to steady fractions(oxidable fraction and residual fraction), and attenuated their migration.

不同时期不同深度填埋层内Cu和Zn形态的差异明显，填埋垃圾的好氧环境的暴露能促使Cu和Zn从稳定态向不稳定态迁移。

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明，渗滤液中Cu大部分为腐殖质络合态，并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变；Zn则主要表现为与S~(2-)的络合，其络合程度随模拟填埋场内还原性环境形成而加剧，生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。

Shanxi Yangling 712100, ChinaAbstract Screening of the effective anti-tumor fractions from acetic ester fraction and water fraction as well as alkaloids fraction and non-alkaloids fraction of Oxytropis Kansuensis on mice bearing S180 and H22 in vivo.

The inhibition effect of chloroform fraction was the most potent, with the inhibition rate about more than 83% to 5 plant pathogenic fungi under the concentration of 15mg/mL. Under the concentration of 15mg/mL, the ethyl acetate fraction and n-butanol fraction thoroughly inhibited the growth of Alternaria solani and Valsa mali, with the inhibition rate up to 100%. The n-butanol fraction showed the highest potent virulence, with EC50 to Alternaria solani and Valsa mali about 0.09 and 0.279 mg/mL respectively.

其中氯仿部分的抑菌效果较好，当质量浓度为15mg/mL时，其对5种植物病原菌的抑制率均在83%以上；15mg/mL乙酸乙酯部分和正丁醇部分分别对番茄早疫病菌和苹果腐烂病菌有强烈且稳定的抑制作用，抑制率达100.00%，正丁醇部分对这两种菌丝生长抑制毒力最好，EC50分别为0.090和0.279mg/mL。

From the point of microstruction,bamboo volume fraction of bundlesheath,single bundle sheath area,fiber width,cell wall thickness increase withthe growth of age,fraction of cell wall changes like density,increases with thegrowth of age,the 2 age-degree bamboo is the biggest.The reason why 2 age-degree fraction of cell wall more than 3 age-degree bamboo is the former has thegreater fraction of parenchyma;1 age-degree bamboo has the greatest fiberlength,fiber length and width ratio and vessel length.The difference in bamboofiber length,vessel length and width among other age-degrees is not distinct.

从构造角度来说，竹材的纤维束比量、单个维管束纤维束面积、纤维宽度、胞壁厚度随着年龄的增大而增大，胞壁率随年龄变化规律与密度相似，随年龄增大而增大，以2度竹最大，2度竹胞壁率比3度竹大主要由于薄壁组织比量较大所致；纤维长度、纤维长宽比、导管长度以1度竹最大，其它年龄纤维长度、导管形态变化不明显。

Cd and Zn mainly occurred in weak acid soluble fraction, reducible fraction and oxidisable fraction, while Pb and Cu mainly occurred in residual fraction.

结果表明，Cd和Zn主要以可提取态存在（即弱酸溶解态、可还原态和可氧化态），而Pb和Cu均以残渣态为主要存在形式。

The results showed the content of acid soluble fraction, reducible fraction, oxidisable fraction and total vanadium showed positive relationship with the adding vanadium in soil, while residual fraction kept constant.

结果表明，土壤中酸可溶态、可还原态、可氧化态钒及总钒与钒施加浓度呈正相关，残渣态钒含量保持稳定。

Among the policies we have written and retained entirely for our own account are (1)$578 million of property coverage for a South American refinery once a loss there exceeds $1 billion;(2)$1 billion of non-cancelable third-party liability coverage for losses arising from acts of terrorism at several large international airlines;(3)￡500 million of property coverage on a large North Sea oil platform, covering losses from terrorism and sabotage, above ￡600 million that the insured retained or reinsured elsewhere; and (4) significant coverage on the Sears Tower, including losses caused by terrorism, above a $500 million threshold.

自从 911 事件发生之后，Ajit 就变得异常忙碌，在我们承接且全部自留在公司帐上的保单，主要有(1)南美洲炼油厂损失超过 10 亿美元以上的 5.78 亿美元意外险(2)数家国际航空公司 10 亿美元恐怖份子攻击事件不得撤销第三责任险(3)北海原油平台 5 亿英镑恐怖份子攻击及恶意破坏的产物意外险，以及超过 6 亿英镑以上业者自留或再保损失(4)芝加哥 Sears 大楼恐怖份子攻击事件超过 5 亿美元以上的损失等；此外我们也接了许多项超大型的意外险，例如世界杯足球赛以及 2002 年冬季奥运等，但不论是那一件个案，我们都尽量避免会发生连锁反应大量累积损失的保单，比如说，我们不会一口气接下位于同一个大都会的办公及住宅大楼大量的意外险，除非排除核子爆炸及后续可能引发的火灾损失。

Www.buffettism.com 巴菲特研究中心 Research Centre for Buffettism avoiding dumb decisions, rather than by making brilliant ones. Since September 11th, Ajit has been particularly busy. Among the policies we have written and retained entirely for our own account are (1)$578 million of property coverage for a South American refinery once a loss there exceeds $1 billion;(2)$1 billion of non-cancelable third-party liability coverage for losses arising from acts of terrorism at several large international airlines;(3)￡ 500 million of property coverage on a large North Sea oil platform, covering losses from terrorism and sabotage, above ￡600 million that the insured retained or reinsured elsewhere; and (4) significant coverage on the Sears Tower, including losses caused by terrorism, above a $500 million threshold. We have written many other jumbo risks as well, such as protection for the World Cup Soccer Tournament and the 2002 Winter Olympics. In all cases, however, we have attempted to avoid writing groups of policies from which losses might seriously aggregate.

In assessing the soundness of their reinsurance protection， insurers must therefore apply a stress test to all participants in the chain， and must contemplate a catastrophe 17 自从 911 事件发生之后，Ajit 就变得异常忙碌，在我们承接且全部自留在公司帐上的保单，主要有(1)南美洲炼油厂损失超过 10 亿美元以上的 5.78 亿美元意外险(2)数家国际航空公司 10 亿美元恐怖份子攻击事件不得撤销第三责任险(3)北海原油平台 5 亿英镑恐怖份子攻击及恶意破坏的产物意外险，以及超过 6 亿英镑以上业者自留或再保损失(4)芝加哥 Sears 大楼恐怖份子攻击事件超过 5 亿美元以上的损失等；此外我们也接了许多项超大型的意外险，例如世界杯足球赛以及 2002 年冬季奥运等，但不论是那一件个案，我们都尽量避免会发生连锁反应大量累积损失的保单，比如说，我们不会一口气接下位于同一个大都会的办公及住宅大楼大量的意外险，除非排除核子爆炸及后续可能引发的火灾损失。

A method dealing with the division of coverage region is discussed in this paper based on certainty coverage. Secondly, under the condition of the connectivity, dynamic programming method is used to optimize the coverage regions and their radiuses, which minimizes the sum of radiuses and reduces the cost of the coverage of the network.

然后在保证网络一定连通性的约束条件下，通过动态规划的方法优化网络覆盖区数量和覆盖半径，使网络内所有覆盖区的半径累加和最小，剔除冗余的节点降低网络的覆盖成本。
