查询词典 a length of

Genomic DNA in eukaryotic cell is organized into nucleosome array and further packaged into higher-order structures. Each nucleosome is composed of a stretch of approximately 147bp DNA wrapping around a histone octamer, and neighbored nucleosomes are connected by linker DNA with length varies from 20bp to 100 bp.

中文摘要真核生物的基因组DNA能够与组蛋白形成核小体结构，这些核小体结构在基因组上线形排列，并进一步折叠成更加紧密和复杂的高级结构。

In order to illustrate the phenomena occurred in the technological experiments, the infiltration dynamics of liquid aluminum into porous media was simulated in accordance with the laws of similitude. The results show that (1) the relation between the displacement of infiltration front and the advancing time is 〓;(2) the pressure of infiltration changes with time according to 〓;(3) the distribution of pressure in the direction of infiltration length is P=a〓+b〓L.(4) the change of temperature or viscosity of molten aluminum affects infiltration velocity in fillers of diameter in the range of 1. 5～5. 5mm very little, but this velocity in fillers of diameter 0.5mm is reduced with the decrease of AL temperature.

为了说明工艺试验中显示的各种现象，作者根据相似原理，采用模拟试验研究了铝液在多孔介质中的渗流过程，得到铝液渗流动力学规律如下：（1）渗流前沿位移—渗流进行时间关系为〓；（2）渗流压强随渗流时间的变化规律为〓；（3）渗流压强沿渗流长度分布为P=a〓+b〓L；（4）铝液温度降低或粘度加大时，对大于1.5mm的颗粒之间的渗流速度影响不大，但使0.5mm颗粒之间渗流速度减小。

In this study we mapped a grain length controlling gene named Lk-4 with SSR and CAPs markers by screening 800 recessive plants in a BC2F2 population derived from a cross of Shuhui527×Xiaoli and backcrossed with Xiaoli as the donor parent.

对F2和BC2F2 群体籽粒大小形状和千粒重的遗传分析表明，回交能将大部分对目的基因效应具有干扰修饰作用的微效基因多态性除去，从而有利于对目的基因型的准确鉴定；在F2和BC2F2群体中只发现两类籽粒长短表现型，即短粒和长粒，并且二者分离比例符合3：1的典型一对等位基因分离比例。

The inheritance of branch number and length of maize tassel was re-studied by means of a mixed inheritance models of quantitative traits of a major gene plus polygene based on parents, F_1, F_2 and backcrosses from two different combinations of maize.

以478×CMI312和丹340 ×CML322等两个组合的 6个世代（P_1，P_2，F_1，F_2，B_1，B_2）为材料，采用数量性状的主基因－多基因混合遗传模型，重新研究了玉米雄穗分枝数和雄穗长度的遗传。

We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers.

我们不知道是谁第一次治疗好了一条断腿，是谁把一个可以在海上航行的船送下水，使税收此计算出了一年的长度，又是谁首次在田野中施肥。

We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers.

我们不知道是谁最先接上折断的腿骨，是谁最先造出适合于航海的船只，是谁最先计算出一年的长度，又是谁最先给田地施肥；但是我们对那些杀人者和破坏者却知之甚详。

We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
