四分圆

Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.

在这一研究内容下，主要研究四个方面的问题：(1)在完成金属波导传输线方程时域形式的基础之上，应用有限积分技术，把波导特征模式的色散传输线方程，化简为一组新的一阶偏微分方程组，该边值问题属一维Dirichlet边值问题，从而便于用蛙跳格式求解，由于是在一维中计算，该方法具有很高计算效率和精度，从而避免了以往为得到金属波导中特征模的时域响应特性，须要求解二阶方程，或用时域有限差分方法求解三维问题的方法，对于后者来说，计算有时是不准确的，或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。

This principle is illustrated in Fig. 5, where the shaded region represents the region of increased margin for the data symbol in the first quadrant.

这一项原则在图 5 中被举例，阴暗的区域表现区域哪里增加边缘为数据符号在那第一个四分圆。

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。

Configuration feature: Constant green small tree, gao Keda 8m, bark brown gray, crack, branch is arranged loose, ramose from bottom to top gradually short, establish body tower look, big branch up or bend downward slightly, rod is long and straight, up extend, 4 arris form, close top shows a circle, it is scale leaf completely, scale leaf hands in each other opposite on rod, clingy rod, see 3 impeller are unripe occasionally, scale leaf grows 1.5-3.5mm, pointed or tip acute is blunt, small incurvate, without candle pink, have gland system, gland body is elliptic, be located in a leaf back radical ministry, individual plant of different of male and female, rare with individual plant.

科 属：柏科。圆柏属。形态特征：常绿小乔木，高可达8m，树皮褐灰色，条裂，枝条排列疏松，分枝自下而上渐短，树体塔形，大枝向上或略向下弯曲，小枝长而直，向上伸展，四棱形，近顶端呈圆形，全为鳞叶，鳞叶在小枝上交互对生，紧贴小枝，偶见三叶轮生，鳞叶长1.5-3.5mm，先端锐尖或钝，微内曲，无蜡粉，有腺体，腺体椭圆形，位于叶背基部，雌雄异株，稀同株。

From these 4 studies, we could got the following conclusions:(1) The CPAI 22 traits could be divided into two categories, with the changing of age, period and cohort, type I traits didn't change, they were Logical vs Affective Orientation, Enterprise, Responsibility, Inferiority vs Self-Acceptance, Optimism vs Pessimism, Face, Family, Defensive, Graciousness vs Meanness; While with the changing of age, period and cohort, type II traits changed, they were Leadership, Self vs. Social Orientation, Veraciousness vs Slickness, Traditionalism vs Modernity, Harmony, Renqing, Meticulousness, Extraversion vs Introversion, Emotionality, Practical Mindedness, Internal vs External Locus of Control, Thrift vs Extravagance, Discipline.

总结上述四个研究的结果，我们可以得出如下结论：（1）CPAI所包含的人格特质可以分为两类，第一类人格特质不随社会发展的时间与空间分布以及年龄、代群发生明显的变化，这些人格特质包含：理智-情感、开拓性、责任感、自卑-自信、乐-悲观、面子、亲情、防御性、宽容-刻薄；第二类人格特质随着社会发展、年龄与代群三个纵向变量的发生一致性变化或者交互变化，这些人格特质包含：领导性、自我-社会取向、老实-圆滑、传统-现代性、和谐性、人情、严谨性、外向性、情绪性、务实性、外控性、节俭性、纪律性；同时，功能差异项目构成的问卷揭示出五个受社会环境影响很大的心理特征，它们分别是：犬儒-现实主义的生活态度、心理适应性、外圆内方的应对风格、自我效能感、个体主义的价值观。

The garden, which was slightly arched, had in its centre, on the summit of a hillock, a fine pointed and conical fir-tree, whence ran, as from the peaked boss of a shield, four grand alleys, and, ranged by twos in between the branchings of these, eight small ones, so that, if the enclosure had been circular, the geometrical plan of the alleys would have resembled a cross superposed on a wheel.

园里的地面是微微隆起的，中间有个稍高部分，一株美丽的圆锥形的枞树耸立在那上面，宛如圆盾中心的突刺，四条宽道从那中心出发，伸向四方，每一条宽道又都有两条小路，各向左右分展出去，各各相通，因此那片园地，假使是圆的话，那些道路所构成的几何图形就象一个加在轮子上面的十字架。
