On the other hand, we make certain study to the nonwandring property of bounded, unbounded operator semigroups ,and give out concrete application.By the theory of semigroups, we establish if {T_n}_(n≥1) is a bounded linear operator sequence onBanach space X_n converging in the sense of Kato to a bounded operator T on theBanach space X , then their nonwandering property can be inherited by each other under the appropriate conditions.

另一方面，本文对有界和无界算子半群的非游荡性也作了特别的研究，并给出了一些具体的应用；利用半群理论，还证明了算子在Kato意义下逼近时，二者之一的非游荡性可被另一个所保持；并得到了几个相应的结果。

Introducing the Darwin's method of treating x-ray diffraction in crystals into Bragg diffraction for multilayer structure, a series of analytical expressions are obtained, which can be used to calculate the reflectivity, the Darwin's width, the minimum number of periods and the energy resolution.

将晶体动力学衍射的Darwin理论运用到多层膜对称Bragg反射中，给出了一系列解析表达式，可计算强度比、反射线角宽度、最小周期数及能量分辨率等。

V! X:{5 N/ l6 _/ P: S With park as the major platform for industrial development, the Longping Hi-tech Park's marching steps will be brisker. We aim at the park's completed area reaching over 10 sq km by 2010, the value of industrial output 18 billion Yuan, 100 hi-tech enterprises, and a national model hi-tech park with intensive high technologies and reputation.

In the antero-posterior X- ray film ,the position of the lag screw should be parallel to the long axis of the neck of femur, slightly above the level of the femoral calcar.

认为加压螺钉的位置应是在正位平行于股骨颈的长轴，位于股骨距稍上的水平，侧位位于股骨颈的中轴线上。

Base start corner to be machined ? X 45 degrees chamfer and painted yellow.

基准是用机器制造的 1/2 * 45 斜面度并油上黄色。

One of the challenges was to avoid having anything look duplicated - each flag on the tower was hand tweaked, I made over 100 different vase types ( 10 different textures X 10 different models with different stretching), most of the textures had dirt masks as map channel 2 and were tweaked after positioning so that textures wouldn't be repetitive either and so on.

挑战之一是如何有效的避免那些东西看起来像是复制出来的-------塔上的每面旗，我都手动调整过，我制作了超过100个不同风格的瓶子（10个不同的纹理和10个不同的模型，配合比例的变化）。

Since any n x n doubly stochastic circulant matrix has a unique representation as a polynomial of degree n - 1 in the shift operator wn, the classification problem of primes in the doubly stochastic circulant matrices can be reduced to the solution of an equation over a doubly stochastic circulant matrix.

由于任一n阶双随机循环矩阵都可以唯一地表示为移位的n-1次一元多项式，从而可把双随机循环矩阵中素元的分类问题简化为解双随机循环矩阵上的一个方程。

By analytic geometry method and solving quadratic equation,a computer simulation algorithm of digital projection under arbitrary scanning locus was proposed.The algorithm is based on the rules of attenuation of monochromatic X-rays.Through mathematical modeling and computer simulation,digital projections of ellipsoid and cylinder in circular and helix scanning modes are exemplified respectively,which are proved to be correct by FDK and PI-line reconstruction algorithms.

介绍了一种利用解析几何和求解二次方程仿真任意扫描轨迹下的锥束射线投影数据算法，该方法基于单色射线贯穿物体的衰减理论，通过数学建模与计算机仿真，给出了椭球、圆柱两种典型模型分别在单圆、螺旋线扫描轨迹下的投影数据仿真结果，并利用FDK和PI线重建算法进行验证，证明了该种数值仿真方法的正确性。

M% e; U5 x M*~ [22] In that sense guilt is the great civilizer, the internal commandment that helps us choose to be kind to each other rather than to join in a stampede of me-firsts.

从这个意义上说，内疚感是人类文明的伟大促进者，它是人类内心的戒律，促使我们选择与人为善，而不去与那些"老子先来"的自私自利者挤成一团你争我抢。

The Yakka can be set up in minutes: just unfold the hull sections, secure the center support and inflate the sides. For pack-down, simply deflate the sides and fold the hull closed. Once folded, its impact-resistant hull measures only 1.50m (59'') x 76cm (30'') and the inflatable bladders are protected by the durable and smooth PVC materials.

香港许多想玩独木舟的人士，但又苦於家裹储存问题因而却步，迟迟无法拥有自己的独木舟， Yakka 的革新概念和设计正正解决了这苦恼的问题，使独木舟活动更易接近和更具有吸引力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
