Because Conference matrices and Hadamard matrices are related to Paley matrices,in this paper we define the normalized Conference matrices and generalized normalized Hadamard matrices,and we show some special properties of them. Also we constructed a doubly even self-orthogonal code from normalized Conference matrix and a doubly even self-dual code from generalized normalized Hadamard matrix.

由于Conference矩阵，Hadamard矩阵与Paley矩阵紧密相联，本文定义了正规Confersnce矩阵和正规Hadamard矩阵，讨论了他们的一些特性，并且利用正规Conference矩阵构造了一个自正交的双偶码刷用正规Hadamard矩阵构造了一种自对偶的双偶码。

The operation methods were chosen according to Hailer index, which were subdivided into four degrees: slight, middle, severe and extreme severe ones.

按不同程度来选择Nuss手术或两次多点或双弧形支架或双支撑架固定法手术，并评价手术是否安全可行和有效。

Fortunately, there are techniques that make Padmasana much safer to learn. Even if you don;t teach full Lotus, you can use the same techniques to protect students in related postures, such as Ardha Baddha Padmottanasana (Half-Bound Half-Lotus Forward Bend), Baddha Konasana, and Janu Sirsasana (Head-to-Knee Pose).

可喜地是，现在有许多技巧可以让学习双盘变得更安全，即使你不教双盘，你也可以让学生在做相关的体位法，使用相同的技巧保护学生，例如： Ardha Baddha Padmottanasana(Half-Bound Half-Lotus Forward Bend直立单盘前弯式) Baddha Konasana坐式曲膝双脚脚掌相对，或是Janu Sirsasana (Head-to-Knee Pose)坐式单脚伸直另一脚单盘脚掌抵在另一腿之内侧。

The Hamiltonian operator of system of Heisenberg chain acts on the complete basis vectors produced with permutation group to form energy matrix.

计算结果：(1)位型[4，2]的第I类自旋交换在格点单、双占据及格点单、双占据共存三种情况时所得矩阵只在对称填充时相同，别况均不同。

The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

摘 要：采用两台JVC3000高速摄像机对中国女子链球优秀运动员张文秀的技术动作进行三维摄影测量，获得较为全面的人体运动学数据；运用SPSS软件对数据进行筛选和相关分析，发现该运动员在旋转时间、轨迹和速度等技术参数方面存在着一些制约成绩提高的问题，诸如双支撑时间短于单支撑时间、各圈(尤其第1圈)的轨迹倾角偏大、加速过程太短、单支撑阶段过于强调加速及双支撑阶段旋转过快、持续加速能力不强等。
