A method for determinating the activities of pectinase was proposed in this paper. It can produce the red-brown amino compounds when 3,5-dinitrosalicylic acid and aldehyde were heated together. The amino compounds had maximum absorbency at 540nm. In certain range, there was a good linear relationship between the amount of reducing sugar and the color of the reaction mixture.

针对QB1502-92标准测定方法测定高活力果胶酶、固定化果胶酶活力存在的实验误差大，重现性及灵敏度差的缺陷，提出了利用3，5-二硝基水杨酸与醛糖共热产生棕红色的氨基化合物，在一定范围内还原糖的量和含有呈色氨基化合物的反应液颜色深浅成正比的原理，在540nm下测其吸光度，从而计算出果胶酶活力的测定方法，并对测定步骤、影响因素及测定中可能出现的问题进行了试验研究。

When the cotton seed cake in the former was detoxified with the solvent containing 0.5% of FeSO4 in advance,the efficiency on feeding fishes was better than that of the undetoxifiad.but the latter could be fed direct to fishes.

在上述用量范围内，未见试验鱼有毒性反应；鱼体营养成份和几项生理指标与对照鱼相当，鱼肉中游离棉酚的含量为0.0009～0.0017％，此值远低于0.02％的食品卫生标准。

The soil profiles and standard penetration test results for SPT N-values at 11 points along the crossbeam direction of the building.

土壤剖面和标准贯入试验结果为六方会谈的N -价值11分，沿横梁方向建设。

However, the cutoff values for these tests are not agreed upon.

By using Roche kit as standard, the amplification efficiency of different reagents were compared by Roche Light Cycler instrument for establishing real-time PCR reaction system. The primers were designed based on signature sequence of chromosomal DNA fragment and caf 1 gene in plasmid pMT1 of Y.pestis. And sensitivity and specificity assay were done with serial diluted Y. pestis EV76 strain and other bacterias. Then 275 Y.

采用SYBRGreenI随机掺入法，以Roche试剂盒为标准，比较两公司的DNA聚合酶，用鼠疫菌310 0 4建立荧光PCR反应体系；针对鼠疫耶尔森氏菌特异的染色体标识序列和质粒上F1抗原基因设计引物，检测其灵敏度和特异性，以盲测试验进行验证；在此基础上鉴定2 75株鼠疫耶尔森氏菌，并测试该法检测脏器污染模拟标本的灵敏度。

Therefore this dissertation concentrates in the investigation on the Q-V characteristics under non-standard lightning impulses mainly including damped oscillation ones by means of experiment and calculation.

为此，本文分别从试验和计算两个方面，开展对非标准雷电波，其中主要是衰减振荡波的电晕伏库特性研究。

Three methods were compared,the results showed that the mothod——rceirculation fumigation under film through PH 3 dynamic deliquescence can reduce fumigation spaces effectively,save CO 2,control the moisture content losses of grain bulk,and the phosphide residue in grain were in accord with the national health standard,the effect of controlling stored-grain insects was obviously.

三种方法的对比试验表明，膜下动态潮解法，有效地减少了熏蒸空间，节省了CO2 ，控制了粮堆的水分散失，粮食中的磷化物残留量低于国家卫生标准，杀虫效果显著。

According to the secondary climatic zoning for highway, this paper carries through the interrelated outdoor and indoor tests and investigations of approximate 20 representative sections of 11 regions in SanBei, and demonstratively brings forward the modificatory recommended soil resilient moduli of SanBei region by integrating the increased degree of soil resilient modulus under the heavy-duty standards of compaction test and contrasting the recommended tabulation of the primary criterion.

按公路二级自然区划选取三北地区11个片区约20条代表路段进行了路基现场以及室内相关试验与调查，结合重型击实标准下模量值的提高程度，对比原规范模量推荐值表，论证提出了修正后的三北地区土基回弹模量推荐值表。
