In this paper by using Suzuki-trotter thoughts,we map 1D quantum Heisenberg chain into an equivalent 2D classical system.
利用Ｓｕｚｕｋｉ－ｔｒｏｔｔｅｒ思想，把１维海森堡链映射为２维经典系统，在ｔｒｏｔｔｅｒ方向采用双链近似，算出反铁磁系统的每个格点的自由能，讨论其热力学性质。
The entanglement teleportation is realized via a channel of entangled thermal mixed states in 1D Heisenberg chains.
本文主要讨论了通过正则变量和非最大纠缠信道可以实现量子隐形传态,用一维海森堡链的热纠缠混合态作为量子信道可以实现纠缠隐形传态,并分析了具有振幅阻尼的量子噪声对隐形传态中各个环节的影响。
Iterative approximation algorithm of Hessian matrix in structural optimization;
结构优化中的海森矩阵的近似迭代方法
The Hessian matrix of every function in this model is constant, so it will be calculated once in the entire optimal process based on interior point method, which speeds up each iteration.
该新模型的海森矩阵是精确的常系数矩阵,在内点法迭代过程中只需要计算一次,从而缩短了每次迭代的计算时间。
Respective characteristics and styles of the achievements attained by the master physicians: Dirac and Heisenberg, have been discussed in the history of the top three physic achievements in 19 th century: thermodynamics, electromagnetics and statistic dynamics.

In the times so called golden years of physics, Heisenberg, Jordan, Pauli, Dirac, and schroedinger played outstanding parts, but Born, Bohr, and Sommerfeld, men of riper age, made major contributions to quantum mechanics, yet they must be regarded as the foremost teachers of that pe.
在量子力学建构这一黄金岁月中,海森伯、泡利、狄拉克、约旦等年青精英和薛定谔发挥了主导作用;而他们的老师:玻恩、玻尔、索末菲等也为此作出了各自重要的贡献。
