查询词典 vector addition

Bradley explained this effect in the context of Newton's corpuscular theory of light, by showing that the aberration angle was given by simple vector addition of the Earth's orbital velocity and the velocity of the corpuscles of light (just as vertically falling raindrops strike a moving object at an angle).

布拉德利解释这种效应的背景下，牛顿corpusculartheoryoflight，经表明像差角度作了简单的载体，增加了地球的轨道速度与速度段体轻(就像垂直下落雨滴罢工运动物体的夹角)。

Methods: The coding region of superoxide dismutase was amplified using PCR method from the E.co1i genome. The PCR product was cloned into PUC19-T vector and sequenced. In addition, the cloned coding region of Mn-SOD was inserted into the expression vector PET-28a to form the recombinant plasmid PET-28a-Mn-SOD and was then transformed into E.coli BL21 for expression.

用PCR方法从大肠杆菌2号基因组中扩增Mn-SOD基因编码区，克隆到pUCm-T Vector，测定核苷酸序列；再将基因编码区克隆到原核表达载体PET-28a，构建含Mn-SOD基因的重组表达质粒，转化到大肠杆菌BL21中进行IPTG诱导表达。

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。
