The result verifies that the discrete model with power series direct discretization method requires 100 memory length to obtain the better approximation, while one with continued fraction direct discretization method requires only 10 order. Thus the continued fraction direct discretization method is preferable to digital realization of fractional order control algorithms in engineering applications.
研究结果表明,幂级数直接离散法得到近似离散模型需要记忆长度为100方可获得较好的近似,而连分式直接离散法近似离散模型为10阶时就可以获得较好的近似,因此连分式直接离散法比较适合于分数阶控制算法的实际工程应用。

In this thesis, a semi-classical model of the force on an atom is used to describe the motion of a two-level atom interacting with a standing wave laser field. The velocity dependent force and momentum diffusion are derived through optical Bloch equations by using the matrix form of the continued fraction technique. By investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom.

成年人学英文的第一课和第二课刊出后,有数位读者写E-mail给我。有一位说道:「一篇文章的每一个单字都查到解释了,但整篇文章就是看不懂,怎麼办?」另一位说:「我的文法很差,没办法写完整的英文句子,要如何补救?」当发音和字汇都掌握住学习要领之后,剩下的就是「读」和「写」了,这才符合学习英文的正确步骤:听→说→读→写。台湾传统的学习方式由「写」开始,再「读」,然后才「说」,最后再去补救「听」力,可以说是背道而行,难怪效果不彰。那麼学习「读」的要诀是什麼呢?当然最重要的是能够了解整个句子的涵义。记得初中的时候背了很多文法规则,考试的分数虽然很高,但是对「读」的能力没有帮助。连那个时候流行的「英语九百句型」,也从来没有耐心读完过。然而我们今天能够看懂中文的文章,难道是因为我们熟悉中文的文法吗?答案是否定的。同样地,一个美国人虽然能阅读报纸,但是要求他做「英文文法分析」,他可能也会傻眼。英文的句子其实不需要去靠文法书中的规则去了解,文法书只应当作参考书,在有疑惑的时候才去查阅。平常应养成「约定成俗」的习惯,就是看别人怎麼用,然后「依样画葫芦」,日积月累,文法规则就化为无形了。因此,要训练「读」的技巧,不应该是靠文法规则,而是要多读。但是在读之前,要具备「了解句子」的基本能力,这就是我们的第三课─了解英文句子的要诀。了解英文句子的关键,在於先抓住「主词」和「动词」。看到一句很长的英文句子,不要害怕:先找主词,再找动词。动词如果是「及物动词」,再去找「受词」。主词、动词、受词之外,剩下的通通当做修饰语,有的修饰主词,有的修饰动词,有的修饰受词,有的修饰全句;任何两个完整的句子都可以用连接词连接起来。以上简单几句话,就是了解英文句子的基本观念。了解英文句子的第二步是熟悉英语的五种基本句型,其中前两种与不及物动词有关,后三种与及物动词有关。以下的句子中,用大括号表示{主词}或{受词},中括号表示,剩下的部份都是修饰语。第一种与不及物动词有关的基本句型叫做「简单不及物句型」(Intransitive Verb,简称I),请背住以下五个句子

Her acne problem worsen after her chicken pox. During those times, my mum did not have any knowledge but to go to get some 'solution'- some 'toad medicine from the shops. Not surprisingly, it did not help my little sister. Now that she's all grown up, she has a pretty face, and like most office ladies, she loves dolling up and and is up to date with the latest fashion. Even photographers says she is very photogenic but the only flaw is that her complexion is bad due the scars left from the uncured acne.
小妹在中学期间患上水痘之后,她的痤疮就一发不可收拾,当时母亲的知识很有限,不知道要到哪去找好的治疗方法,只是到药材店做些蛤蟆药煮来喝,但问题还是不能决解,现在小妹已经长大了,很爱打扮,也很讲求时髦,脸型长得好,很上镜头(连摄影师都这么说,就可惜她的皮肤,给她的整体形象扣了不少的分数。
