用来表示

UTF-8 is a variable-length character encoding, which in this instance means-that it uses 1 to 4 bytes per symbol. So, the first UTF-8 byte is used for-encoding ASCII, giving the character set full backwards compatibility with

UTF-8是一个变长的字符编码，也就是说它会用1到4个字节去表示一个字符。1个字节的UTF-8字符是用来编码ASCII的，这样也就让它可以和ASCII完全兼容。

" The Greek military leader and historian Xenophon, who served with Greek mercenaries in Persia, first used the Greek word paradeisos adopted from the Avestan word to refer to the Persian kings' and nobles' parks or pleasure grounds. This Greek word extended to mean "garden" or "orchard was an obvious choice for translators of the Bible into Greek to use both for the Garden of Eden and the Abode of the Blessed, or heaven. The Greek word was adopted into Late Latin and was used much as we might expect in its biblical senses in ecclesiastical Latin. The Old English word paradis taken from Latin is found, but our word probably really established itself in Middle English (first recorded before 1200), derived both from Latin and from Old French, which had adopted the word from Latin. paradise.

曾随希腊雇佣军到波斯服役的希腊军事将领和历史学家色诺芬，首先使用了希腊语词paradeisos，，该词采用了阿维斯陀词，指波斯国王和贵族们的花园或游乐场，这个希腊词衍生到表示"花园"或"果园"，显然是译者在把《圣经》翻译成希腊文时所做出的选择，以用来表明伊甸园和天国或天堂，有这两种含义的希腊词被引入后期的拉丁语中且当它们在教会拉丁文（后期拉丁语paradisus 中意为《圣经》方面的意义时被更广泛地使用，古英语paradis 一词来自拉丁文，但我们用的这个词可能在中古英语（首次记录在1200年前）中真正确立了起来，人们发现它源于拉丁文和从拉丁文中采纳了这个词的古法语

For intramolecular electron transfer reactions in solution,the fluctuations of the intramolecular vibrational modes are much faster than that of solvent mode.Thus,the reaction-diffusion equation is commonly used to describe the motion of solvent,with a sink function to treat the vibrational high-frequency mode.Based on this theory-so -called the Sumi-Marcus theory,we proposed an imaginary-time split operator approach to solve the reaction-diffusion equation.The approach is applied to evaluate the intermolecular ET rate between oxazine 1 and N,N-dimethlaniline.By measuring the two average survival times of the donor state probability and the rate constant in long time limit,the full kinetics of the ET is revealed with a variety of sink functions.

对于扩散控制的溶液中的电子转移反应，分子内振动模的运动比溶剂运动快很多，Sumi-Marcus理论提出用反应扩散方程(reaction-diffusion equation)处理溶剂的扩散运动，而分子内的振动用sink函数来表示，我们基于此理论发展了用虚时间分裂算符的方法(imaginary-time Split operator approach)解反应扩散方程，并将其应用于嗪1(oxazine 1，OX1)和N，N-二甲基苯胺分子之间的电子转移反应，Sink函数采用几种不同的微扰表达式，通过计算得到给体几率衰减的两种平均速率和长时间极限下的速率常数，揭示了该体系电子转移过程中的一些动力学性质。

In this paper,pose representation by quaternions are researched.With the basic quaternion algebra,the "quaternion based rotations combination theorem" is introduced and proved theoretically.On the basis of this theorem,a method for compute of pose nonliear state transfer function and its linearization is purposed.Then,the computing of the measurement function and the linearization is studied.With the Extended Kalman Filter,the pose is tracked and estimated.

A device or component of some dataprocessing machines that permits the expression of instructions in a semifixed computer program by the insertion of pins, plugs, or wires into sockets or hubs in the device, in a pattern to represent instructions.

某些数据处理机的一种设备或部件，可按表示指令的模式，用插针、插头或导线插入板上的插座或插孔的方法来表示半固定计算机程序的指令。

In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

为了使设计者从道路线路设计的繁重计算统计工作中解脱出来，在研究了局部方案间内在关联的基础上，提出了将局部方案分解为更小单位的逻辑方案，用有向网络图表示逻辑方案间的拓扑关系，采用节点－弧段联合数据结构来表示网络图；同时基于最短路径理论，提出了在网络图中智能化搜索综合指标最优的逻辑方案集，自动形成整体方案的组合优化算法。

The protein sequence is composed of 20 amino acids. Each amino acid is named with a unique one-letter code. A terminus code is added to indicate the two ends of the sequence. Thus twenty-one-bit binary numbers can be used to encode the amino acids in the sequence.

蛋白质序列则是由20种胺基酸所组成，一般我们会以单ㄧ字母来表示一个胺基酸，而序列都会有终止码去表示序列的前后端，因此我们一般会用21个的二元数字去对每个胺基酸做编码。

Use couldn't have + a past participle to refer to past impossibilities.

用 couldn't have +过去分词来表示过去不可能发生的事，表示一种推测。

The Laws now express dimensions with approximate metric equivalents (followed by traditional units in brackets), though popular use tends to continue to use traditional units in English-speaking countries with a relatively recent history of metrication, such as Britain.

像英国一样，英语国家也开始使用了米制单位，但他们还是倾向于用传统的英制单位。而如今的足球规则是用与英制单位约等的米制单位来表示的（其后括号内用传统单位标注）。
