根据农田植被层上方的温湿风梯度观测资料,采用基于莫宁-奥布霍夫相似理论的廓线梯度法计算了农田植被层上方的湍流通量,进而确定出拖曳系数、斯坦顿数和道尔顿数。收藏指正
2.On the basis of theory of similarity and gas-solid fluidization, the four dimensionless criteria, the Froude number, the Flow number, the ratio of static height to diameter of bed and solid to-gas density ratio, describing similarity of fluidized beds were obtained.
本研究以相似原理和气固流态化理论为基础,首次获得了控制大颗粒流化床床层动力学相似行为的相似条件,即:傅鲁德数、流化数、静床高和床径的比率、固气密度比。收藏指正
3.Economy? series of guar gums are absorbed very rapidly on the cellulose fibres owing to their structural similarity with cellulose and in addition they carry a large number of Hydroxyl groups, suitable for the formation of Hydrogen bonds.
这里的瓜尔胶系列产品都能很快地被纤维细胞所吸收,是由于它们的细胞结构和纤维细胞非常相像,其次它们带有大量的羟基团适合氢键的形成。收藏指正
4.To each of these characteristic monuments there is attached by a similarity of taste, fashion, and attitude, a certain number of houses scattered about in different quarters and which the eyes of the connoisseur easily distinguishes and furnishes with a date. When one knows how to look, one finds the spirit of a century, and the physiognomy of a king, even in the knocker on a door.
由于格调、式样和气势相类似,各有一定数量的民房与上述每座独具特色的历史古迹紧密相联系。这些民房分散在不同的街区,但行家的目光还是一眼便可把它们区分开来,并确定其年代,只要善于识别,哪怕是一把敲门槌,也能从中发现某个时代的精神和某个国王的面貌。收藏指正
5.RESULTS:The complete VP1 gene of CVB2 Yunnan strain had a total length of 846bp and without initiator codon and terminator codon. The highest similarity of VP1 gene with Ohio 1 strain(GenBank logging number:AF081312) nucleotide and amino acid sequence was 98% .
结果:CVB2云南分离株VP1基因全长约846bp,无起始密码及终止密码,与Ohio-1株(GenBank登录号:AF081312)核苷酸、氨基酸序列同源性最高为98%。收藏指正
6.Sequence analysis showed that the gene had typical characteristics encoding Wnt protein family and shared 26% similarity to mouse and human Wnt10a,hence,the gene was named as Sjwnt10a(GenBank Accession Number:DQ643829).
该基因编码的氨基酸序列具有Wnt家族蛋白的典型特征,与人、鼠Wnt10a的氨基酸序列同源性均为26%,推测为血吸虫的Wnt10a基因,命名为Sjwnt10a(Gen BanK登录号DQ643829)。收藏指正
7.The results show that the Mach number and Stokes number are decisive similarity criterion,and the modeling errors of the particle impacting velocity and angle on nozzle wall are less than 5% and 3°,respectively.
结果表明:马赫数和斯托克斯数(Stk)是两相流动的决定性相似准则,其对粒子与壁面撞击速度的模化误差小于5%,撞击角度的模化误差小于3°;收藏指正
8.The distribution of the Ag-stained NORs(Ag-NORs),the Ag-stained associated acro-centric chromosomes(Ag-AAC)and the Ag-stained acrocentrics association(Ag-AA)in thetablet users and controls was a random one in Denver Group Level. The similarity in mode and frequency of Ag-NORs in the two groups suggested thatthe“Tablet Norethindroni Compositae” had no effect on the number of active rRNAgene.
服药组和对照组的银染核仁形成区(Ag-NOR_s)、参与联合的银染近端着丝粒染色体(Ag-AAC)和银染近端着丝粒染色体联合(Ag-AA)在丹佛体制分组水平上呈随机分布,两组的Ag-NOR 众数和频率相近,表明“复方炔诺酮片”对服药妇女有活性的rRNA 基因的数量没有影响。收藏指正
9.Investigation shows that Reynolds number, the similarity parameter of the van-body truck model experiment in the wind tunnel, need not be as large as that of a real operating full-size truck. The Reynolds number will do as long as it is in the range of automatic modeling of the experimental graph and the critical value is Re=0.5xl06(width of the truck is characteristic length).
