查询词典 irrational fraction

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.

以甘肃棘豆提取物的乙酸乙酯部位、水相部位，以及生物碱和非生物碱部位，对荷S180和H22肿瘤小鼠进行了体内抗肿瘤实验。

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。

4 Is a rational fraction .But 1/3 is a irrational fraction.

四分之一是真分数，而三分之一是假分数。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
