查询词典 Chs.

The current research points out that for the CFCHS joints the linear extrapolation method can be used for chords,whereas the quadratic extrapolation method must be used for braces.The hot spot stress distributions on the CFCHS joints tend to be more uniform and their SCFs become smaller significantly,compared with the CHS joints.Axial tension on the brace puts the CFCHS joints at a disadvantage,which produces higher SCFs than axial compression.The effects of nondimensional geometric parameters β,τ and γ on SCFs of the chords of the CFCHS joints are basically the same as those of the CHS joints,but for the braces,there is a bit difference in the effects of parameters β,τ and γ between the two kinds of joints.Concrete has the function of improving the CFCHS joint rigidity and then decreasing SCFs which is expected to increase fatigue strength,but concrete strength grade does not exert significant influence on SCFs.

研究表明：CFCHS节点的热点应力，对主管可采用线性外推方法，对支管需采用二次外推方法；相比CHS节点，CFCHS节点的热点应力分布趋于均匀，SCF显著减小；CFCHS节点支管轴向受拉比受压不利，SCF增大；CFCHS节点几何参数β，τ，γ对主管SCF的影响效应与CHS节点基本一致，但是对支管SCF的影响效应与CHS节点有些差异；混凝土的作用主要是改善CFCHS节点刚度，从而降低SCF，并预期可提高疲劳强度，但混凝土自身强度等级的高低没有显著影响节点的SCF。

与裸子植物相比，被子植物中CHS基因发生较多的置换，但两者受到的选择作用相似。

The real-time quantitative PCR results showed that the expression level of two genes did not be affected by HHO obviously, whereas, the expression level of CHS gene had down regulation of different degree, except in 1.0 mM of HHO's concentration. It meaned that CHS gene is probably related with the metabolism of allelochemical.4. The Chalcone synthase gene (EaCHS1) of E.

荧光定量PCR的结果表明，萜类代谢途径中的两个关键酶基因的表达水平，没有因为羟基泽兰酮的诱导而表现出显著的差异；CHS基因的表达水平，除了在羟基泽兰酮处理浓度为1.0 mM时的差异不显著之外，在其他处理浓度均有不同程度的下调，说明该基因与化感物质的代谢途径相关。4。

The publicizing about CHS should be strengthened; the proper measures should be taken to improve the community inhabitants' attitude to CHS; and the connotation of CHS should be continuingly enriched.

1。加强CHS的宣传教育；2。采取适当的策略改进社区居民对CHS态度；3。不断丰富、完善优质CHS的内涵。

Taken together, these results indicate that cosuppression of the tobacco chs gene can occur using the equivalent Petunia gene, and demonstrate a linkage between the expression level of chs mRNA, cyanidin content, and flower color in transgenic tobacco plants.

综合而言，本研究提供了广泛的实验证据，说明菸草chs基因的共同抑制作用是可以透过别种植物如矮牵牛的相似基因而发挥作用，导致转殖菸草产生白色花朶；并清楚显示chs mRNA表现量、花青素含量及转殖菸草花朶颜色的关联性。

In this study, the exon2 fragments of CHS genes in ferns, gymnosperms and angiosperms, a total of 22 fragments from 12 systematic families, were amplified successfully by PCR, and then sequenced (PCR amplification of the exon 2 from musci is in process).

本实验用PCR方法从蕨类，裸子植物和被子植物，共12个科中均成功地扩增了22个CHS基因外显子2片段（从藓类中扩增CHS基因外显子2的工作正在进行）。

So to study the evolution of CHS genes, the ideal data set should include the sequences of CHS genes from musci and other systematic groups of higher rank.

依据类黄酮物质存在与否，可推测CHS基因最早出现在藓类，因此，为研究CHS基因的进化，取材最好包括藓类和更高等的分类群。

For the substitution and transversion of nucleotide in the same family, CHS sequences from Poaceae, Solanaceae and Papilionoideae evolved at nearly the same rate.

我们从水稻的基因组BAC文库中克隆了2个CHS基因，即B1-P7和B2-P5.B1-P7包含有完整的CHS基因，B2-P5则只克隆了外显子2和3'端的非编码区。

Northern blot analysis showed that total chs mRNA levels were greatly decreased in white-flowered transformants. By contrast, chs mRNA expression was induced in pink-flowered transformants.

北方氏墨点分析法显示，白色花朶转殖株内chs mRNA的总量大幅下降；相反的，花色属粉红色的转殖株，chs mRNA的总量却显著增加。

RT-PCR analysis showed that the relative level of endogenous tobacco chs mRNA was less than that of the transgenic Petunia chsA mRNA in white-flowered lines.
