分级

By n-butanol extraction, ammonium sulfate fractionation and sodium chloride dialyzation, the partially purified enzyme was gained by means of gel filtration on sephadex G-150 column, and some properties of the enzyme were determined.

方法］以DFRKN-1为提酶材料，经正丁醇提取，硫酸按分级沉淀分离，透析获得酶的粗提取液，用SephadexG-150凝胶过滤柱层析纯化，获得纯化碱性磷酸酶，并测定纯化碱性磷酸酶的理化性质。

AB-Ⅰshowed single and symmetrical peak, a light yellow powder was obtained after dialyzation and freeze-drying. AB-Ⅱand AB-Ⅲwere devided into two parts, collected the main peak, we gained AB-Ⅱ-b which was yellow powder and AB-Ⅲ-b which was brown powder.

AB-Ⅰ、AB-Ⅱ和AB-Ⅲ分别再通过Sepharose CL-4B凝胶层析进一步分级，AB-Ⅰ得到单一对称峰，透析干燥后为淡黄色粉末，AB-Ⅱ和AB-Ⅲ在主峰之前分别有一小峰，收集主峰，得到AB-Ⅱ-b和AB-Ⅲ-b，透析干燥后分别呈黄色和褐色粉末。

There was no correlation between CL）X-2 expression and pathohistological types, dinical stage, pathohistological grade and age.

COX-2表达与患者病理类型、手术病理分期、病理分级及年龄无关，与术后残留灶直径有显著相关性（P〈0.01）。

After that,we find the one of key factors which affect the classification effects for ultra-fine powder is dispersity of ultra-fine powder.

认为影响分级效果的关键因素之一是超细粉体的分散性，另一关键因素是粒子在不同状况下的运动特性。

Nitrate contents of main vegetables and fruits in Yaan city's markets were determined by disulfonic acid colorimetry method. Nitrate pollution levels were evaluated by evaluation criteria of nitrate content classification in China.

方法］采用酚二磺酸比色法对雅安市城区市售主要蔬菜和水果硝酸盐含量进行了测定，并参照我国硝酸盐含量分级评价标准对其硝酸盐污染状况进行了评价。

Those categories are normal,, and dysplastic.

二位专家认为是极好，一位认为是好—最后将分级为极好。

Down-regulation of XIAP could improve the electrobiological activity and seizure behavior in PHT-CBZ resistant rats.

下调XIAP表达可以协助AEDs改善耐药大鼠的电生理活动，降低点燃后发作分级，提示MAP参与了难治性癫痫的耐药。

Numbness symptoms were significantly related to electrodiagnosis findings of neurophysiological grading and sensory conduction velocity. The severity of numbness symptoms correlated with the abnormality of the electrodiagnosis results.

将此三大症状与电学诊断结果进行相关性分析后，我们发现麻木针刺感觉与电学检查指标的相关性较高，分别与神经综合分级呈正相关，与感觉神经传导速率呈负相关。

Results The results indicated that acute toxicity LD50 of Elsholtzia seed oil was classified as no toxicity.

结果 野生香薷籽油以急性毒性半数致死量(LD50)毒性分级属实际无毒。

Thinking comprehensively of geological environment, ecological and nature environment, making surely the contents and emphasis of the environmental quantity assessment, establishing the index system of the environmental impact assessment and its ratings standard, studying the evaluation theories and its methods of the EQA, revealing time-space variety regulation of environmental quantity, studying the time-space distributes regulation of mineral pit water、waste heap eluviate water, tailingspile waste water and its heavy metals pollution and migration rules in surface water, groundwater, water department bottom mire, soil, applying division form R/ S analysis to research the development trend of heavy metals monitors data in water and soil, using mathematical statistics, gray theories, neural network, fuzzy evaluation, time order analysis to establish the forecast model of the EQA in mine geotechnical system.

综合考虑系统内地质环境、生态环境、自然环境，确定矿山岩土工程系统环境质量评价内容与重点，创建矿山岩土工程系统环境质量评价指标体系及其分级标准，研究矿山岩土工程系统环境质量评价理论和评价方法，揭示矿山岩土工程系统环境质量时空变化规律，研究矿坑水、废石场淋滤水、尾矿库废水时空分布规律及其引起的地表水、地下水、水系底泥、土壤等重金属污染及迁移规律，应用分形R／S分析研究水土监测时间序列发展趋势，再用数理统计、灰色理论、神经网络、模糊评价、时序分析等建立岩土工程系统环境质量预测模型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
