This paper studies the electrode combination of 3D tunnel DC focused method. At first, the authors calculate and analyze the current distribution of two point power sources with the same electrical property, and indicate that as currents exclude each other, current density has a maximum at a certain depth along the perpendicular bisector of the two point power sources and the depth is directly proportional to the distance between them.

本文研究了三维坑道直流聚焦法电极组合，首先计算分析了两个同性点电源的电流分布规律，指出由于电流的相互排斥作用，电流密度在这两个点电源的中垂线下一定深度处产生最大值，这个深度与这两个点源之间的距离成正比。

The traditional type is the categorical syllogism in which both premises and the conclusion are simple declarative statements that are constructed using only three simple terms between them, each term appearing twice (as a subject and as a predicate):"All men are mortal; no gods are mortal; therefore no men are gods."

从而无法提高解题的速度和精确程度。我现在把这段文字翻译如下：在逻辑学中，有效的演绎推理有两个前提和一个结论。传统的形式是直言三段论。在直言三段论中，两个前提和一个结论是简单的陈述，其构成仅仅包含三个项，每个项要出现两次，例如：所有的人都是要死的，神是不朽的，因此没有人是神。

At the normal state, porphyrin molecules do not have EPR signal. However, light excitation may cause a transition of porphyrin molecules from singlet to triplet. At the same time, the change from diamagnetism to paramagnetism occurred to porphyrin molecules. In this case, the two un-paired electrons are nearby each other and cause a strong interaction, giving EPR signal with sharp peak at g =2.000. The g value increased with an increase in electron cloud density.

常态下卟啉分子没有EPR信号，在光的激发下，卟啉分子由原来的逆磁性分子变成顺磁性的激发三重态分子，这种激发三重态分子在分子轨道上具有两个未成对电子，这两个电子相距很近，彼此之间发生很强的相互作用而产生电子，它的 g 值随卟啉共轭体系平均电子云密度增大而变大。

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

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.

在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。

In this paper, thermogram was used to do human face recognition. The thermogram of human face was captured from infrared camera. Image processing technologies were used to preprocess the captured thermogram. Then several features were extracted from the processed thermogram. These features included the distribution of temperature statistics, the perimeter of the face, the length/width ratio of the smallest rectangle which contained the face, and the triangle formed from the three lowest temperature points of the two cheeks and the chin. A three-layer back-propagation neural network was used as the recognition tool.

Because the techniques of the biochemical waste treatment are very important, the techniques of the cultivation of the microorganism have received more attention in recent years. A study is conducted to analyze the steady states and dynamic bechavior of the reactions of the cell-substrate and the prey-predator interaction in two chemostats in series. For the reaction of cell-substrate in two chemostats in series, if the specific growth rate of the Monod model is used for the cell , there are three types of steady states for this reaction system. These three types of steady states and stability are analyzed in detail. The dynamic behavior of this reaction system is analyzed by the numerical method and computer graphs. The results show that the dynamic behavior of this system consists of stable steady states.

A systematic analysis of the icosahedral hierarchic structure in the 3D icosahedral quasicrystal and its approximants have been made. There is an icosahedron at the center surrounded by 12 icosahedra. If two neighboring icosahedra are vertex-sharing, the multi-shell Mackay cluster consisting of 127 atoms will form. If two neighboring icosahedra penetrate into each other, the multi-shell Samson-Bergman-Pauling cluster consisting of 137 atoms will form.
