Due to begin to present differentiation,IEC-6 cells grew slowly.2.This study design and compose three pairs siRNAs to RPS20 of rats,and they interference the expression of RPS20 on the aspect of mRNA and protein successfully,and prove their validity.3.After interference,IEC-6 cells cytoplasm present vacuolization,and its migration,and proliferation were suppressed,but there was no apoptosis to happen.These results indicate that interfering expression of RPS20 may affect the function of digestion and absorption and gastrointestinal mucosa healing,which is in accordance with condition of low level on digestive and absorptive function and gastrointestinal mucosa healing.

本课题设计并合成了3对针对大鼠RPS20的siRNAs，而且都能够有效地抑制IEC-6细胞RPS20mRNA与蛋白的表达，表明了序列的有效性；3 IEC-6细胞胞浆空泡化，并且迁移、增殖能力受到抑制，但并没有导致细胞早期凋亡的发生，该结果提示干扰RPS20可能影响IEC-6细胞的消化吸收功能和胃肠粘膜损伤修复功能，与前期收集的脾气虚证患者消化吸收功能下降、黏膜损伤修复能力下降等表现相符合。

Such as: calibrating the laser system, calibrating the measurement region and focusing the CCD camera for the diffuser passage with complex shape, selecting the best incidence angle for the laser sheet,, setting the time parameter including the time between pulses and the time between records, designing the laser system, and selecting water fog with 1～5μm diameter as seedings for PIV measurement after comparing several particles. All of the work is useful to accumulate the PIV measurement experience in turbomachinery. 2. Experimental research of the unsteady flow in diffusers The instantaneous velocity fields within the vaneless and vaned diffuser were measured by using PIV technique.

本文在国内首次进行PIV测量系统对离心风机扩压器内部非定常流动的测量，为此，作者作了必要的实验前期工作：双谐振激光器工作特性的标定；针对扩压器复杂的流道形状，解决了片光源照射区域位置的标定和CCD相机的聚焦等问题；为复杂流道形状的扩压器内部流动的PIV测量选择了最佳片光源入射角度；选择了合适的PIV测量时间参数；为实现非定常内流的PIV测量设计了PIV系统的光路布置；根据非接触测量示踪粒子的选取原则，对几种示踪粒子进行了筛选，最终1～5μm的水雾粒子在本文实验条件下获得最佳效果。

In previous study, a strain of Xanthomonas sp. that could degrade completely Poly alcohol had been isolated.

前期研究分离到一株能高效降解并矿化聚乙烯醇的黄单胞菌(Xanthomonas sp。)。

the in case there exists simultaneously the conditions of the quantity of rattus flavipectus and xenopsylla cheopis in the this en-demic region over70%of the total and the density of rattus flavipectus indoors over5%and the rattus flavipectus index of xenopsylla cheopis over,then it will anticipate an epidemic of plague.

家鼠鼠疫疫区黄胸鼠和印鼠客蚤占总数的70%以上，当室内黄胸鼠密度大于5%及黄胸鼠体印鼠客蚤指数大于1等三项指标同时成立是鼠疫流行前期的预兆。

Abroad of punk although the earlier period be also a kind of depravity of underground culture, publicize be original meaning anti- oppress and to reality of disaffection, with as for think change this kind of present condition.To now be gradual development to become a kind of young, have imagination dint, creative power, there is vitality, drive not tradition restrain of of culture, even is to life of fine look forward to, although some part still incline toward violence and gray, this kind of violence what to say youngly dare to play to dare to do, not local of dozen dozen kill, dying live come what of.

国外的朋克，虽然早前期也是一种堕落的地下文化，宣传予以本义反压迫和现实的不满，至于想改变这种目前condition.to现在逐步发展成为一个种年轻，有凭借的想象力，创造力，有活力，驱动器没有传统约束的文化，甚至是生命的罚款期待，虽然有些部分仍倾向暴力和灰色的，这种暴力行为说些什么youngly敢于发挥，不敢做，而不是当地的十几个十几个杀死，死亡的活来有什么of.why动摇一个机构在国内的变化呢？

Over the years, our laboratory hasfound that Zizania DNA introgression could induce a large number of genetic and epigeneticchanges in some introgression lines.

我们实验室的前期工作发现将菰的基因组DNA导入水稻中能诱导水稻基因组获得渐渗杂交系发生广泛的基因组变异和表观遗传变异。

Based on the single experiment, orthogonal experiment was designed to optimize extraction technology parameters such as temperature, extraction time and enzyme dosage of jujube juice from Zizyphus Jujube Mill grown in Yanchuan Shaanxi Province.

以延川团枣为材料，在前期单因素试验的基础上采用正交设计试验方案，对温度、提取时间和酶用量等提取红枣汁的工艺参数进行优化。

The challenging features most strongly associated with major complications were mature 4+ nuclear sclerotic cataracts and zonular pathology (antecedent trauma and pseudoexfoliation), which had odds ratios of 18.9 (95% CI, 3.1-117, P=0.002) and 26.2 (95% CI, 4.3-159, P=0.003), respectively.

与主要并发症关系最为密切的疑难杂症特征是成熟期4级晶核硬度和韧带病理因素（前期损伤和假鳞片样脱皮），优势率分别为18.9（95%的可信区间，3.1-117， P=0.002）和26.2（95%的可信区间，4.3-159， P=0.003）。

Shannon-Wiener diversity index, Simpson diversity index and evenness index all show similar trend of change. The diversity indexes and evenness index of zoobenthos in rice-duck farming ecosystems are higher than those in normal paddy during the early stage of rice growth, but are in the reverse trend during the later stage.

水稻各生育时期常规稻田和稻鸭共作稻田底栖动物的Shannon-Wiener多样性指数、Simpson多样性指数和Pielou均匀度指数变化趋势相似，均为水稻生育前期稻鸭共作稻田的生物多样性指数和均匀度指数高于常规稻田，而后期低于常规稻田。

The total number of zoobenthos in rice-duck farming ecosystem declines remarkably during the early stage of rice growth, but almost equals that of conventional paddy at late growth stage.

水稻生育前期，稻鸭共作使底栖动物的个体总数减少较大，后期与常规稻田差异较小。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
