邵金峰 《凯里学院学报》2002,20(4):76-77

叶嘉莹女士在其著作中认为中国传统诗词批评的特性是由中国语文之特性造成的,这种看法不够正确。本文对叶女士的观点进行了分析,指出是中国传统文化导致了中国传统诗词批评的特点。  相似文献   

施用钾肥对小麦幼苗干物重及体内营养状况的影响     

汪建飞 《安徽科技学院学报》1991,(2)

在黄红壤、黄褐土和砂姜黑土上,进行不同水平钾肥盆钵土培试验,结果表明,在正常的施肥水平,施用钾肥均能促进小麦幼苗干物重的增加,施钾过量则会造成干物重下降,施钾水平与小麦全株干物重呈二次曲线相关,在三种土壤上,相关系数分别为0.8335,0.8960,0.9913,当施钾水平为0.1gK_2O/kg土时,黄红壤和砂姜黑土上生长的小麦植株干物重达最大值,分别为0.267和0.240克/株,施钾为0.2gK_2O/kg土时,黄褐土上的小麦干物重达最大值,为0.264克/株,在正常的施肥水平,施用钾肥有利于植株中N、P、K、Mn的积累,对Ca、Mg、Fe、Cu、Mo的吸收则有抑制作用。  相似文献

Separation and identification of cis and trans isomers of 2-butene-1,4-diol and lafutidine by HPLC and LC-MS     

Pan CX  Xu XZ  He HM  Cai XJ  Zhang XJ 《Journal of Zhejiang University. Science. B》2005,6(1):74-78

The cis and trans isomers separation of2-butene- 1,4-diol and lafutidine were studied by HPLC on two kinds of chiral columns: (S,S)-Whelk-O 1 and ChiraSpher. The isomers of 2-butene-1,4-diol can be separated on both chiral columns while the isomers of lafutidine can only be resolved on ChiraSpher column. The influence of different type and amount of mobile phase modifier on the isomers separation was extensively studied. The resolution of cis and trans isomers of 2-butene-1,4-diol was 2.61 on (S,S)-Whelk-O 1 column with hexane-ethanol (97:3, v/v) as the mobile phase. The resolution of lafutidine was 1.89 on ChiraSpher column with hexane-ethanol-THF-diethylamine (92:3:5:0.1, v/v/v/v) as the mobile phase. LC-MS methods were developed to identify the isomer peaks.  相似文献   

关于图〈c4,m〉和图(U)s=1 c2(4,ms)的k--优美性     

武建春  曾朝英 《集宁师专学报》2002,24(4)

我们熟知c4是优美图,在c4的基础上,马克杰等在文[1]中已证明了〈c4,8〉和c4(2,m)是优美图.本文将〈c4,8〉推广到〈c4,m〉,并证明了它是k-优美图;将一个图〈c4,m〉推广到l个c4(2,ms)(s=1,2,…,l)的并也是k-优美图  相似文献   

Controversial opinion: evaluation of <Emphasis Type="Italic">EGR1</Emphasis> and <Emphasis Type="Italic">LAMA2</Emphasis> loci for high myopia in Chinese populations     

Fang-yu Lin  Zhu Huang  Ning Lu  Wei Chen  Hui Fang  Wei Han 《Journal of Zhejiang University. Science. B》2016,17(3):225-235

Functional studies have suggested the important role of early growth response 1 (EGR1) and Laminin α2-chain (LAMA2) in human eye development. Genetic studies have reported a significant association of the single nucleotide polymorphism (SNP) in the LAMA2 gene with myopia. This study aimed to evaluate the association of the tagging SNPs (tSNPs) in the EGR1 and LAMA2 genes with high myopia in two independent Han Chinese populations. Four tSNPs (rs11743810 in the EGR1 gene; rs2571575, rs9321170, and rs1889891 in the LAMA2 gene) were selected, according to the HapMap database (http://hapmap.ncbi.nlm.nih.gov), and were genotyped using the ligase detection reaction (LDR) approach for 167 Han Chinese nuclear families with extremely highly myopic offspring (<?10.0 diopters) and an independent group with 485 extremely highly myopic cases (<?10.0 diopters) and 499 controls. Direct sequencing was used to confirm the LDR results in twenty randomly selected subjects. Family-based association analysis was performed using the family-based association test (FBAT) software package (Version 1.5.5). Population-based association analysis was performed using the Chi-square test. The association analysis power was estimated using online software (http://design.cs.ucla.edu). The FBAT demonstrated that all four tSNPs tested did not show association with high myopia (P>0.05). Haplotype analysis of tSNPs in the LAMA2 genes also did not show a significant association (P>0.05). Meanwhile, population-based association analysis also showed no significant association results with high myopia (P>0.05). On the basis of our family- and population-based analyses for the Han Chinese population, we did not find positive association signals of the four SNPs in the LAMA2 and EGR1 genes with high myopia.  相似文献

再议母语在外语习得中的作用及其启示     

林敏 《双语学习》2007,(10M):169-171

母语迁移的本质是外语习得中客观存在的、复杂的认知心理过程。在强调关注母语负迁移时，教师也应重视并全面地认识母语的正迁移尤其是其在认知层面的作用，必须用动态的、多层面的视角看待母语迁移，从而正确指导外语教学。  相似文献
