查询词典 A.T.

The 'permanent truth' is close to Russell's 'apriority' of induction. However, in my opinion, this kind of permanent truth or apriority doesn't have any important sense since the principle of anti-induction, i.e., ' if a t 1 — b t b ,……, a t n — b t n then probably A ?

这种"永真性"与罗素关于归纳原则的"先验性"十分接近，然而，在笔者看来，这样的永真性和先验性没有多大意义，因为反归纳原则即如果 a t 1 — b t b ，……， a t n — b t n 则大概 A ？

A strong A-T bias was found in the nucleotide sequence of mitochondrial genome of the Mongolian wolf. All the transfer RNA genes could be folded into the typical cloverleaf-shaped structure except tRNA-Ser, which lacked the "DHU" arm.

序列碱基的组成存在明显的A-T偏好性。tRNA基因中除tRNA-Ser缺少双氢尿嘧啶臂以外，其余均能折叠成典型的三叶草二级结构。

The study was conducted by management consultants, A T Kearney, and Cambridge University's Business School.

该项研究是由作为管理顾问的A T Kearney和剑桥大学经济学院进行的。

However, there are many moreA/T���G/C changes than G/C→A/T in a single arm, which would lead to an increasing trend in GC content and suggest that the composition is not at equilibrium.

然而，在每个臂上，A/T→G/C 的突变数目却大于G/C→A/T的，这表明回文序列的成分并没有达到平衡，并且GC含量有上升的趋势。

While using a rifle (or similar two-handed weapon), your accuracy in V.A.T.S. is significantly increased.

使用步枪时，你在V.A.T.S模式下的命中率会有较大提高。

The nucleotide composition and the phylogenetic relationship among 14 species in Coreidae based on 412bp sequences of Cyt b gene were studied. The results showed: the average contents of T, C, A and G were 34.2 %、11.4 %、35.7 % and 18.7 %, respectively; The content of A+T (69.9 %) was obviously higher than that of G+C (30.1 %), and come up to 82.8% at the third position of codon.

以线粒体细胞色素b基因作为分子标记，首次对缘蝽科4亚科14种昆虫进行序列测定，获得Cytb基因412bp的序列片段，该片段中碱基T、C、A、G的平均含量分别为34.2%、11.4%、35.7 %和18.7 %，A+T平均含量为69.9 %，明显高于G+C含量（30.1 %）。

Result The results show that A+T contents of CO Ⅱ genes of Libellulidae are lower (68.6%) in Insecta, which proves Odonata is an original group. Every sequence includes 2 Cys, which differs from the other groups of Insecta. Do not agree with the view of raising Macrominae into Macromidae. Agree with the views of putting both Aeshnidae and Cordulegastridae into Aeshnidea, and raising Gomphidae into a superfamily. Order of the evolution relationship of 5 families is: Gomphidae→Cordulegastridae→Aeshnidae→Corduliidae→Libellulidae.

结果］CO Ⅱ的A+T含量较低(68.6%)，说明蜻蜓目是一比较原始的类群；每条序列均含有2个半胱氨酸，这一点有别于其他类群昆虫；不支持将大蜻亚科上升为科的观点；支持将大蜓科和蜓科归入蜓总科，而将春蜓科上升为总科的观点；差翅亚目5科之间的进化关系由慢到快依次为：春蜓科→大蜓科→蜓科→伪蜻科→蜻科。

Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

对分别采自辽东湾、莱州湾、海州湾和舟山的三疣梭子蟹4个野生群体的线粒体16S rRNA和COⅠ基因片段进行了扩增和测序，分别得到长度为524bp和658bp的片段。2段序列的碱基组成均显示较高的A+T比例（16S rRNA基因70.8%，COⅠ基因63%），这与果蝇、虾类、蟹类等无脊椎动物的16S rRNA和COⅠ基因片段研究结果相似。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
