首先发展国小中年级学童分数概念试题，接著在年级及性别间做检定，其次探讨国小中年级学童分数概念的等分、简单分数、单位量、等值分数概念的表现及直观规律的运用，最后分析犯错误类型的学童在分数概念的表现。

Application of organic fertilizer decreased the proportion of total hydrolyzable N fraction and hydrolyzable NH4-N fraction, and increased the proportion of nonhydrolyzable N fraction and unidentified hydrolyzable N fraction, respectively.

比较有机区与惯行区，显示施有机肥料会使可水解全氮所占比例下降，而不可水解氮的比例上升，水解性铵态氮的比例下降，不可辨认的水解性氮所占比例增加。显示所施入之有机肥主要补充至不可水解氮、不可辨认的水解性氮划份。

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。
