抑制性

• These data indicate that gabaergic inhibition makes an important contribution to the direction - dependent frequency tuning of most ic neurons . corticofugal modulation of the excitatory and inhibitory ftcs of most ic neurons was more pronounced at one sound direction than the other . sound direction effects on frequency tuning characteristics may undergo a postnatal development due to the development of excitation and inhibition integration
  通过对幼年(出生后第四周)和成年蝙蝠下丘听神经元频率调谐的方向敏感性的比较，发现幼年蝙蝠频率调谐的方向敏感性比成年蝙蝠差，并认为可能是动物发育过程中，下丘的兴奋性和抑制性输入的整合也有一个发育的过程。
• We should not underestimate the effects of outside competition and also should strengthen supervision and management from the government . with regards to the railway management model , this paper figures that , considering the reality of our transportation systems , we can choose a mixed model named " separation of infrastructure from operation + regional companies " and at the same time , we should effectively deal with the matter of ' way access authority "
  关于铁路运价政策的问题，本文分析了铁路的垄断性对运价的影响，认为，放开铁路运价后铁路形成垄断价格的可能性不大，因此不会导致铁路运价的上涨;分析了铁路运价的机理，阐述了运能对运价影响的间接性和不确定性，运量对铁路运价影响的直接性、周期性和双向性，竞争对运价影响的抑制性和不平衡性。
• This study showed that the mt and sharpness of frequency tuning curves increased as the sound direction changed from contralateral to ipsilateral azimuthal angles . it suggests that sound direction effect on frequency tuning may be through the complex interplay between the excitatory and inhibitory inputs . the application of gaba ( a ) antagonist , bicuculline , lowered all mts but the application did not abolish direction - dependent variation in mt
  听皮层的抑制性影响使大多数神经元在蝙蝠最敏感的声源方位c - 40的频率分辨能力明显提高，同时使c - 40和i - 40的最低阈值的差别进一步增大，提高了信噪比，提高下丘听神经元对声源方位和最佳频率的分辨能力。
• The deleted mutant pap gene was also cloned into yeast secreted expression ppic9k vector to form ppic9k ~ 3 , then the vector was transferred into pachia pastoris gs115 strain . the specific expression protein was secreted into the medium after inducing with methanol and the protein amount reached about 50 - 60 u g per millilitre measured by uv - absorbed methods in the supernatant of the medium via high density fermentation . sds - page results showed that there was one protein band in the gel which molecular weight was about 34ku
  将缺失型pap基因克隆于酵母分泌型表达载体ppicgk构成重组载体，然后导入毕赤酵母（ p8chianastoris ）菌株gslls细胞中，在甲醇的诱导下，经过酵母高密度发酵进行pap的表达，经sds page分析，结果表明，在培养基上清液中含有一明显的特异性蛋臼条带，大小为34ku ，经western blotting分析，该蛋白与法国pap抗血清有特异性反应，体外活性检测表明该蛋白对tmv的侵染性具有高度的抑制性，说明该pap基因在毕赤酵母gs中也得到了正确表达。
• In this way , the author concludes the obstacles in the physics studying process in the middle school , after reading a lot of relative articles and practicing in the classroom . besides , we also investigate the negative effects of the student ' s lacking of imagination on the building and development of their creative thoughts
  作者阅读了大量的相关文章和专著，并利用一切机会到课堂教学中去实践，通过大量的调查和访谈，总结得出中学生在物理学习中表现的相应的创造性思维的障碍，即学生在物理知识的学习和应用中出现的思维联想活动量和速度方面的迟缓、贫乏以及联想散漫对学一生创造性的发生和发展造成抑制性、干扰性和混乱的影响。
• But four enterococcus grew quickly and hadn " t delaying period , the final period of logarithm growing of all tested strains were 12 hour for i acidophilus pb1 and a878 ; 24 hour for bifidobacteria pba and inf ; 8 - 10 hour for enterococcus ml , pb2 , a30 , a31 and bacillus abticism2 the growth inhibition of escherichia coli , shigellosis , salmonell by the fermented liquor of eight probiotics bacteria was tested
  确定各菌株对数生长期末期分别为： pb1和a878 ： 12h ； inf和pba ： 24h ； pb2 、 m1 、 a30 、 a31 、 m2 ： 8 - 10h 。采用牛津杯法测定八种潜在益生菌对大肠杆菌、痢疾杆菌、沙门氏菌的抑制性，结果表明，嗜酸乳杆菌pb1 、 a878和双歧杆菌pba 、 inf具有较强的抑菌能力，对三种致病菌能够形成明显的抑菌圈，而且对三种致病菌的抑菌能力明显不同。
• The inhibition mechanisms of pb1 , a878 , pba , inf were some organic acids and antibacterial substance in fermented liquor . l . acidophilus strains pb1 , a878 mixed with enterococcus strains ml , pb2 , a30 , a31 respectively in the ratio of 1 : 1 in the mrs cultures , co - cultural and single liquor inhibition to the enterpathogens were tested in the terminal fermentation
  将pb1和a878分别与m1 、 pb2 、 a30 、 a31以1 : 1的比例混合发酵后，测定联合菌株对致病菌的抑制性，结果表明pb1与各球菌联合后，可以互利生长，其中复合较好的为pb1与m1和a30 。
• The elements can be classified into four grades according to the importance of their influence on the whole function system . on the base of the results of correlation analysis on the data obtained through a questionnaire survey on tourists and residents , restraining elements and promoting elements can be divided . city function system of international destination cities thus can be defined as the structured system composed of inter - affected elements , which complete the essential function of an international destination city
  根据旅游者及居民对城市功能要素的评价和对总体功能评价的问卷调查结果，这些复杂的要素可以按其对总体功能作用力的大小分为四个等级，并且不同功能要素对于城市总体功能的作用方式各不相同，包括对总体功能主要起明显抑制作用的抑制性因素以及起明显提升和完善作用的激励性因素和兼有两种作用的复合性要素。
