The present paper studies the structure of the set of non-wandering points of a continuous map from a Graph(i.e., one-dimensional connected compact branched manifold) into itself.

本文主要研究了图(即一维紧致连通的分支流形)上连续自映射的非游荡集的结构。

Secondly, by using the connection, we prove that the minimal continuous semi-flow is the minimal continuous flow if its time-one map is open, and for any minimal continuous semi-flow, there is an invariant residual set such that the restriction to the set is a minimal continuous flow.

为此，我们首先建立了它与其时间1映射极小集的联系；然后，利用这种联系证明了：若时间1映射为开映射，则它是极小的连续流，并且一般地说来，对任意极小连续半流，存在不变的剩余集，使得它在这不变集上的限制是极小的连续流。

From two-dimensional contour map,continuous "band" segregation of sulfur and non-continuous "band" segregation of phosphorus in center of cross section were o...

从大梁钢坯横截面整体的原位统计分布二维成分等高图可以直观的看出，在连铸坯横截面上中心部位，硫形成一条较连续的"带状"偏析，磷形成一条不连续的"带状"偏析，其它元素中心"带状"偏析不明显。

LetJbe a continuous map of a unit square into itself and f can be descendent. This paperpresents slecific featrue for f with homochinic points.

设f是可降的二维自映射，本文给出了这类自映射有异状点的特征──存在f的链回归点，但不是周期点，并且f的队极限点集与周期点集的交非空。

And the effects of length of data N to the approximate entropy of chaotic system isalso analyzed.All these are accomplished by examining several time series produced by a surperposition of white noise and noise-free data.It uses the discrete system logistic map and continuous system Lorenz attractoras the examples.

以Logistic方程描述的离散系统和Lorenz方程描述的连续系统为例，采用白噪声和无噪声信号以不同的信噪比混迭而成数据的方法，分析了相同数据长度N，不同信噪比下，混沌系统近似熵的变化；相同信噪比，不同数据长度对系统近似熵的影响。

Letbe a compact metric space, f: X→X a continuous map, and K(X,H a compact metric space consisting of all nonempty compact subsets of X.

设为紧致度量空间， f： X→X连续， K(X，H是 X所有非空紧致子集构成的紧致度量空间。

Based on ABB s IRB140 mini industrial robot,this paper analyzed a 6 DOF multi-joint industrial robot in kinematics,established its kinematics model,proposed a specific simulation algorithm for robot work spaces describing,and generated a continuous work space map,which have significant referenced value in robot kinematics,barrier avoidance,computer control and robotics education.

文章以瑞典ABB公司生产的IRB140型小型工业机器人为例，对空间六自由度多关节机器人进行了运动学分析，建立了该类型机器人的运动学模型，提出了空间六自由度多关节机器人连续工作容积的仿真算法，并根据此算法生成了该机器人的连续工作容积图，这对机器人动力学、机器人避障、微机控制和机器人教学等方面的研究有重要的参考价值。

The fibrewise separation condition holds important status in the TOP_b categorythe objects are the fibrewise topological spaces over B,for two objects (X,p and,a morphism from X to Y is a continuous map such that p=q o Φ..

中文摘要：纤维分离条件在TOP_B范畴对象是以B为基的纤维拓扑空间，对于对象(X，p，，它们之间的态射是连续映射Φ：X→Y，满足p=q οΦ。

A logicaldomain is used as a reference and the mesh movingis implemented according to an appropriate domain transformation.With sometraditional moving mesh methods,the meshes in physical domain may be tangled.To avoid this,the transformations are constructed based on harmonic mapping.Agood feature of the adaptive methods based on harmonic mapping is that existence,uniqueness and non-singularity for the continuous map can be guaranteed fromthe theory of harmonic maps.

在移动网格方法中，需要引进一个逻辑区域作为参考，网格的移动往往通过一个区域变换来实现，网格可能发生缠绕的问题是移动网格方法中一个一直没有解决的问题，我们利用调和映射来构造区域间的变换，使得变换的存在唯一生有了理论的保证，这就为避免网格缠绕打下了基础。

200 forepart pregnant women with ASA Ⅰ～Ⅱgrade who free will stop gestation,they were divided into 4 groups randomly :P group was simplicity propofol; F group, T group and K group was mainlined fentanyl 0.75μg/kg,tramadol 1mg/kg,ketamine0.2mg/kg respective before propofol abduction, and continuous detected MAP,HR,SpO2 in the operation, and to note first dosage and total dosage of propofol, revival time, leave hospital time, ill reactivity in the operation.

200例ASAⅠ～Ⅱ级、自愿终止妊娠的早孕妇女随机分为四组：P组，单纯异丙酚麻醉组；F组、T组、K组在异丙酚诱导前分别静注芬太尼0.75μg/kg、曲马多1mg/kg、氯胺酮0.2mg/kg。术中连续监测MAP、HR和 SpO2。记录各组病人异丙酚的首剂量和总剂量、苏醒时间、离院时间及术中术毕不良反应的发生情况。

The role of the environment is very important.

的作用，环境是非常重要的。

At that time, the High Court of England and Wales Court of Queen's Bench president of William Murray, Lord Mansfield in June 22, 1772 ruling:"No matter then there is the inconvenience, but there must be a decision, I can not say that this case under the law in England are permitted or authorized; are so black should be released."

当时的英格兰及威尔士高等法院王座法庭院长William Murray， Lord Mansfield于1772年6月22日宣判：「无论有那麽不便，但总要有个决定，我不能说这件案在英格兰法律之下是准许或认可；所以黑人是应该被释放。
