两三个

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。

In addition, some modifications on several computational methods are also presented. Using LMTO method the electronic structure of several systems are studied, and some results are obtained. They are: The ideal Nb (100) surface has three surface states, the multi-layer relaxed surface has two surface states. The surface energy of the ideal surface is higher than that of the relaxed surface, that means that the multi-layer relaxed surface is more stable than the former one, which supports the LEED results. The mono-layer relaxed Ag (111) surface is the most stable one among several" stable surface models"presented by several researchers. The surface energy of Ag (111) surface is higher than that of surface Ag (001), which supports some experimental results such as different reaction rate at different surface orientations for the same material. The surafce states of Si (111) surface not only locate near the Fermi level, but also in the valence band, which agrees well with Cohen's conclusion. Si (111)-H is an effective model for analysing the surface states and H adsorbed on the back surface is a good method for improving the convincingness of the results obtained on thinner slab models. The surface stability depends on three different kinds of MoSi〓(001) surfaces, the surface with mono-layer Si is the most stable one, and the surface with Mo at the first layer is the most unstable one among them. These are consistant with the Kemoda's experimental results. The valence bands of clean or K adsorbed CdTe (111) surface agrees well with the synchrotron radiation studies. The surface of CdTe (111) consists of four kinds of surface models which show different surface electronic structures and different surface structure stabilities. The conclusion agrees well with Wu's experimental work. The different absorbed alkali metals on the CdTe (111) surface give different adsorption characteristics which have relations not only with the valence electrons, but also with the core ones of the alkali metals. The electonic structures of Si-C alloys are different from that of Si-Ge alloys, and the energy band gaps of Si-C alloys do not increase linearly with Carbon concentration, our conclusion supports Alexander's results, but conflicts with Soref's one.

现分述如下： LMTO方法及其应用方面：1）通过对Nb（100）表面电子态分析发现清洁理想表面有三个表面态，多层弛豫表面有两个表面态；表面能大小说明多层弛豫表面更稳定，支持了LEED结果。2）通过对采用不同方法获得的几种不同Ag（111）表面稳定结构的表面能计算分析，给出了单层弛豫表面为Ag（111）表面的最稳定结构；从Ag（111）单层弛豫表面和Ag（001）表面的表面能比较，发现了Ag（001）表面表面能要比Ag（111）小的，表明了同种物质不同表面取向将表现出不同物理、化学性质，这是与实验中得出的结论是吻合的，3）通过对Si（111）表面态分析，不仅发现了Si（111）表面不仅具有居于费米能级附近的悬挂键所对应的表面态，而且还有很多表面态位于价带能量范围内，与Cohen等结果一致，H饱和slab模型背表面相当于增加了slab层的厚度，是一有效的变相增加slab层厚的方法，弛豫表面较清洁理想表面价带谱们低能端的少许移动，预示着总能降低，说明弛豫表面较清洁理想表面稳定。4）MoSi〓具有三种表面，从费米能级上态密度值大小得到单层Si表面最稳定，Mo原子为表层原子的表面最不稳定，双层Si原子表面居中的结论，这与Kemoda等人实验结果是一致的。5）通过对CdTe（111）表面表面电子态、表面结构稳定性及表面H、碱金属吸附的电子结构系列研究，不仅得出了CdTe（111）清洁及碱金属K吸附价带谱与同步辐射光电子谱相吻合的结果，而且发现了CdTe（111）表面具有四类不同原子近邻特征，表现出四类不同的表面结构及电子结构特征：不同表面态分布、不同的表面结构稳定性（表层原子与次层原子成三键有一悬挂键的表面要比表层原子与次层原子成一键有三悬挂键稳定（与Wu等人实验结果一致））、不同的H吸附特性。

My baby is now 5-month, and three months before the development of height and weight were normal, 61 centimeters height, weight 12 kg, since the first three months after the reduction in appetite, eating横抱milk does not like the original one can eat 120 milliliters of milk, to four months when the first can only eat 40 milliliters of milk, after more than hospital treatment, eating MAMIAI, no obvious Pikexin electuary results, a month ago, went to Beijing Children's Hospital to see a doctor, opened Xiaoerkang, athletes Xiaoshi Oral Liquid and so on, has just started to eat better when, a few days later without effect, because the spleen and stomach weakness should not lead to effective absorption of nutrition, started missing Zinc, growth and development is almost stopped, sparse hair, nearly two months of height, weight, no significant growth, but also mental state line, is consistent with the symptoms described in medical rickets disease, do not know how good the spleen and stomach as soon as possible conditioning to restore growth and development.

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.

And he said, Espagniole; and being a little recover'd, let me know by all the Signs he could possibly make, how much he was in my Debt for his Deliverance; Seignior, said I, with as much Spanish as I could make up, we will talk afterwards; but we must fight now; if you have any Strength left, take this Pistol, and Sword, and lay about you; he took them very thankfully, and no sooner had he the Arms in his Hands, but as if they had put new Vigour into him, he flew upon his Murtherers, like a Fury, and had cut two of them in Pieces, in an instant; for the Truth is, as the whole was a Surprize to them; so the poor Creatures were so much frighted with the Noise of our Pieces, that they fell down for meer Amazement, and Fear; and had no more Power to attempt their own Escape, than their Flesh had to resist our Shot; and that was the Case of those Five that Friday shot at in the Boat; for as three of them fell with the Hurt they receiv'd, so the other two fell with the Fright.

我一路向那可怜的俘虏跑去。前面已经说过，那可怜的有胡子的人这时正躺在野人们所坐的地方和大海之间的沙滩上。那两个正要动手杀他的屠夫，在我们放头一枪时，早已吓得魂不附体。他们丢开了俘虏，拼命向海边跑去，跳上了一只独木船。这时，那群野人中也有三个向同一方面逃跑。我回头吩咐星期五，要他追过去向他们开火。他立即明白了我的意思。向前跑了约四十码，跑到离他们较近的地方，就向那批野人开枪。起初我以为他把他们通通打死了，因为我看到他们一下子都倒在船里了。可是不久我又看到他们中有两个人很快又坐起来。尽管这样，他也打死了两个，打伤了一个；那个受伤的倒在船舱里，仿佛死了一般。

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.
