查询词典 negative

A satisfied cytologic smear, improvement of the smear preparation, understanding the particularity of the disease and cytologists's skill in diagnosis are critical to decrease the false-negative rate.

Results 336strains of pathogenic bacteria were separated from the urine sample of2865cases and the detectable rate was11.73%of the336separated strains the number of strains of gram negative bacilli was226,the gram positive cocci is92and the fungi is18.the positive rate of escherichia coli was the highest followed by co-agulase negative staphylococci,klebsiella pneumoniae and blue verditer pseudomonas.highest resistance to penicillins and cephalosporins was obsered.

结果 从2865份尿标本中分离出336株病原菌，检出率为11.73%。其中革兰阴性杆菌226株，革兰阳性球菌92株，真菌18株。阳性率最高的是大肠埃希菌，其次是凝固酶阴性葡萄球菌、克雷伯菌、铜绿假单胞菌。药敏结果对青霉素类、头孢类抗生素的耐药率较高。

Results The diagnostic sensitivity, specificity, positive/negative predictive value, positive/negative likelihood ratio and Youden's index in rheumatoid arthritis patients were 69.4%, 96.8%, 89.1%/94.1%, 19.28/0.317 and 0.658 respectively.

结果 本法对类风湿关节炎的诊断敏感性为69.4%，特异性为96.8%，阳性预测值为89.1%，阴性预测值为94.1%，阳性似然比为19.28，阴性似然比为0.317，Youden指数为0.658。

Tail Length, Tail Moment, Tail DNA Percentage, and correction rate were compared between the improved software and the original one, and epidemiological indices for the improved software were also calculated and analyzed, including sensitivity, specificity, Youden index, crude agreement, adjusted agreement, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio.

比较改进前后的尾长、尾矩、尾DNA百分含量上的差异、改进前后分析正确率差异、以及改进后的软件以不同DNA损伤级别为截断值判定阳性结果的灵敏度、特异度、Youden指数、粗一致性、调整一致性、阳性预测值、阴性预测值、阳性似然比和阴性似然比。

The analysis of correlation indicated that tobacco breeding with higher potassium content has the characteristics of higher stalk height, wider stalk circumference, longer leaf and more leaf number comparatively. The correlations between potassium content and nicotin among top, middle and bottom tobacco leaves were all negative. The correlation among potassium content and malondialdehyde,superoxide dismutase, conductance ratio; and protein, solubility sugar, chlorophyl and free water/bondage water were all attained marked level, however, the essence of correlation was different: the former was negative but the latter was positive. 4.The analysis of heterosis demonstrated there were different degree heterosis in the potassium content of tobacco leaf and other correlated characters, including agriculture, physiology and biochemistry.

相关分析表明，烟叶钾含量性状与株高、茎围和最大叶长的相关性达到了显著和极显著的水平，与叶数的相关虽未达到显著水平，但相关程度相对较高；烟叶钾含量与烟碱在上、中、下三部位叶之间均呈负相关关系，中部叶烟碱与烟叶钾含量的相关达到了极显著水平；烟叶钾含量性状与丙二醛、SOD和电导率以及与蛋白质、可溶性糖、叶绿素和自由水/束缚水之间的相关性均未达显著水平，但相关性质不同，烟叶钾含量性状与前三者之间表现负相关关系，而与后四者之间呈正相关关系；4。

One result of this was an unbalancing of the positive-negative force, by accentuating one or the other; to feel things demanded the negative force; to express through things, and direct and manage them, required the positive force.

这样的一个后果是正负力量的不平衡，不是强调这一种力量，就是强调了另一种力量；感觉事物要求负的力量；通过事物进行表达，并指导和处理它们，要求正的力量。

This text introduced a kind of health care and deodorized insole which releases negative ion,this kind of insole using Anion negative ion additive which takes natural mineral nano-aterial as chief ingredient.

介绍一种以天然矿物纳米材料为主的Anion负离子添加剂制备的释放负离子的保健防臭鞋垫，利用羟基负离子的杀菌抑菌作用，达到防臭保健的目的。

If a cervical Gram stain is positive for Gram-negative intracellular diplococci, the probability of PID greatly increases; if negative, it is of little use.

如果宫颈涂片提示细胞内革兰染色阴性双球菌，盆腔炎的可能性大大提高；否则，宫颈涂片几乎没有诊断价值。

If a cervical Gram stain is positivefor Gram-negative intracellular diplococci, the probability of PIDgreatly increases; if negative, it is of little use.
