结果山梨酸钾可明显引起微核率的上升，与对照组差异显著(P05)或极显著(P01)，不引起染色体畸变率的明显上升。3种物质均可降低山梨酸钾诱发的微核率和染色体畸变率。

This text aims at the difference of several representative geology conditions in Yang Shui mining area, carried on the primary election to the mining method of Yang Shui mining area, introduced the new theories of numerical optimization choice of mining method that are fuzzy mathematics and artificial neural network etc, based on the existing mining methods that are feasible, adopt the fuzzy optimization choice principle of flexible neural networks, and synthesize several experts and fieldworkers' opinion, built up the related mathematical model and revised model, carried on processing of programming through computer, thus established each optimization mining project under several representative geology conditions in Yang Shui mining area, and carried on optimizing to the existent unreasonable parameter in mining project;have the great significance to aim at each kind of geology condition for each mining area to adjust the mining method in time in the course of mining, abandon chronically unreasonable mining method, full reclaim the mine's resource, lower the dilution rate、 loss rate of mineral mining, raise the production capacity of stope and economic benefit of mine.

本文针对洋水矿区几种典型地质条件差异，对洋水矿区采矿方法进行了初选，介绍了模糊数学和人工神经网络等采矿方法数值优选新理论，在现有可行性采矿方法的基础上，采用弹性神经网络模糊优选原理，并综合多位专家及现场工作者的意见，建立了相关的数学模型及修正模型，通过计算机进行编程处理，从而确立了洋水矿区几种典型地质条件下各自的最优采矿方案，并针对采矿方案中存在的不合理参数进行了优化，为各矿区针对各类地质条件在采矿过程中及时调整采矿方法，摈弃习惯性的不合理采矿方法，充分回收矿山资源、降低矿石开采的贫化率、损失率，提高采场生产能力以及矿山经济效益具有重大意义。

Objective To compare the efficiency of insecticides toxicity to different houseflies strains with two methods.

Objective To compare the efficiency of insecticides toxicity to different houseflies strains with two methods.

目的用两种生物检测方法———点滴法与喂饲法检测杀虫剂对家蝇的毒力，比较这两种方法检测结果的差异。

The nutrients and the blood glucose lowering effect of the two different types of pumpkins were also compared, which indicated that the main nutrient difference type of the two kinds of pumpkin is the content of sugar, and the low-sugar type pumpkin had the better hypoglycaemic effect.

通过对两种不同品种的南瓜果实营养成分的含量及降血糖效果的比较可知，实验采用的两种南瓜营养成分的差异主要是糖含量不同，低糖型南瓜提取的PCE-C的降血糖效果强于高糖型南瓜。

After extraction and cleanup, the samples were detected by GC/MS. The LOQ and average recovery ratio were 5.6～18.2μg/kg and 67.7%～102.3% respectively, while RSD was less than 10.6%. The results show the QuEchERS method can be used for the determination of organophosphorus pesticide residues in vegetables.

其采用一种新的样品前处理方法，从蔬菜中提取净化残留农药（包括11种有机磷农药），运用GC/MS进行分析检测，根据有机磷农药种类差异，其最小检出限在5.6～18.2μg/kg之间，回收率在67.7％～105.3％之间，相对标准偏差不大于10.6％，实验表明本方法适用蔬菜中有机磷农药多残留分析。

In SGK321 with expression of CpTI and Bt insecticidal protein genes, both petal and leaf showed significantly higher insect resistant activity than bud and boll heart.

结果表明：7月中旬两种转基因抗虫棉抗虫效果均较好，尤其是CpTI-Bt棉棉叶和花瓣对4龄幼虫3天内致死率为92%以上；8月中旬两种转基因棉的抗虫活性均明显降低，且Bt棉的杀虫活性显著低于CpTI-Bt棉，其幼虫死亡率与对照受体棉中16的死亡率之间无显著差异，仅显著抑制了幼虫的生长；石远321(SGK321受体品系)的花瓣具有一定的抗虫活性，可显著降低取食幼虫的体重，甚至造成部分幼虫死亡；CpTI-Bt棉中，花瓣和棉叶的抗虫性明显高于蕾和铃心。

In order to detect the concentration of the urine protein β_2-MG,ALb,IgG and THP.

表明2种温度贮存的尿标本，4种蛋白检测结果无显著差异。ALb、IgG和THP的测定值在随意尿和24h尿最有相关性，γ分别为0.7565，0.7845及0.7837。

The results suggested that insecticide resistance in German cockroach field populations may be correlated with elevated activity of CarE.

结论德国小蠊抗性品系和敏感品系在CarE生化特征上的差异，显示出德国小蠊抗性品系对几种拟除虫菊酯类杀虫剂产生的高度抗性，与其体内CarE活性的提高有密切关系，表明CarE活性的提高是北京地区野外德国小蠊品系普遍存在的一种抗性机制。

These results imply that there are some similarities between the pituitary and gonadal function disturbance in EILST and KYD rats, but their levels are different. There are pathological changes in kidney structures of KYD rats, but not in those of EILST rats.

基于这些结果，可以认为两种状态在性腺轴功能紊乱方面存在一定的相同之处，但程度不同；两种状态对大鼠肾脏结构与功能和代谢的影响存在很大的差异，&肾阳虚&使大鼠肾脏出现病理性变化，而&运动性低血睾酮&则尚未引起这种损害。
