| 1. | The repressor is essentially a negative control mechanism .
阻遏物基本上是一种负控制机制。 |
| 2. | Spleen cells from negative control mice did not proliferate upon restimulation
3和3刁，而生理盐水对照组增汛不显著。 |
| 3. | Note : “ + ” denotes bacterial growth and “ - ” denotes no bacterial growth . the positive control had bacterial growth and the negative control had no bacterial growth
注： “ + ”表示有菌生长， “ - ”表示无菌生长。阳性对照有细菌生长，阴性对照无菌生长。 |
| 4. | Histopathological examination revealed that most of the ulcer were re - epithelialization in the large and moderate doses groups , but in negative control group , most of the ulcer were not healed at the 14th day after operation
结果：在伤后14天内，复方壳聚糖膜剂外贴可使溃疡面积和容积缩小的速度及表皮完全覆盖率均高于空白对照组。 |
| 5. | It is efficient for flow cytometric analysis when fresh platelet riched plasma ( fprp ) was set as negative control , thrombin actived fprp and liquid nitrogen treated fprp were set as positive control respectivelv
除了fcm常用的同型对照外，文中还将fpr 、凝血酶激活fprp和液氮处理fprp作为血小板标准阴性、阳性对照，直接应用于fcm分析，且效果良好。 |
| 6. | 5 . prepare the oligonucleotide microarray add 16 prepared probes into 384 - pole plate , meantime , add p2 , low homologic probes and probe buffer in the same concentration as positive control , blank control and negative control respectively . spot microarray as designed by the spotting machine
5 .寡核昔酸微阵列的制备以同等浓度的反义链引物咫作为阳性对照，以探针缓冲液作为空白对照，以无关探针作为阴性对照，与制备好的16条寡核昔酸探针，同时加人384孔板。 |
| 7. | For multiplex pcr , primers specific for z and y a , which are involved in the dsb , were employed . and also , a pair of primers of act1 was used as a negative control . in this experiment , we also used yku70 as a positive control , since it has been well defined as a dsb end binding protein
虽然这一发现只是我们工作的一个开端，但是基于这一开端，两个层面的研究工作将被很大程度地拓宽，一是泛素系统不仅只是在dna修复的prr路径起作用，而是可能涉及dna修复的各种不同路径。 |
| 8. | 2 > on the basis of the experimental excavating robot , several energy saving controls with multi function valve control are investigated in this paper , which include negative control , positive control and load sensing control . because of some defaults of these controls , this paper proposes some improvements on them , which have been proved to be effective in experiments
2 、以试验型挖掘机器人为对象，对多种阀控节能控制进行了深入研究，其中包括负流量控制、正流量控制和负荷传感控制，针对这些节能控制方式的不足提出了多种改进方案，并分别进行了试验验证，效果良好。 |
| 9. | In the study , respiratory problems and blue ear were not observed on all the pigs after challenged with prrsv strain ch - 1a . but the rectal temperatures of the pigs in the negative control groups ( plers1neo - immunized group and mock group ) were higher than the pigs immunized with the dna vaccines
Prrsv的感染一般为亚临床表现，在本试验中，攻毒后所有的小猪都没有出现呼吸困难、耳朵发兰等症状，但空白对照猪和空质粒接种猪的体温要高于基因疫苗免疫猪和灭活苗免疫猪，最高可达40石c 。 |
| 10. | A new method for intrinsic terminator prediction based on rnall , an rna local secondary structure prediction algorithm developed recently , and two u - tail score schemas are developed . by optimizing three parameters thermodynamic energy of rna hairpin structure , u - tail t weight , and u - tail hybridization energy , the method can recognize 92 . 25 of known terminators while rejecting 98 . 48 of predicted rna local secondary structures in coding regions negative control as false intrinsic terminators in e . coli . this method was applied to scan the genome of synechococcus sp
在过去二十年中,不少研究者已开始研究如何用计算方法来预测转录终止信号，如brendel和trifonov的双核苷酸分布矩阵法dinucleotide distribution matrix carafa等的统计方法transterm和rnamotif法等，这些方法都从不同方面考虑了rna二级结构和u -尾部的特征，而gester的预测模型则设定rna二级发夹结构是不依赖终止子的唯一因素。 |
