State Key Laboratory of Millimeter Waves, Southeast University , Nanjing 210096, ChinaIn this paper, it is proven that the divergence relationship of electric-field and magnetic-field is non-zero even in charge-free regions, when the electric-field and magnetic-field are calculated with Alternating Direction Implicit Finite-Difference Time-Domain method, and the concrete expression of the divergence relationship is derived.

摘要该文证明了即使在无源区域，交替方向隐式时域有限差分法所给出的电磁场量不满足零散度关系，同时推导出了该散度关系的具体表达式。

The alternating group iterative method is used to solve the implicit scheme and the Crank-Nicolson scheme of the dispersive equation.

数值试验对色散方程的隐格式与Crank-Nicolson格式分别应用交替分组迭代求解。

Furthermore, we constructed group explicit method, alternating group explicit method and alternating section explicit-implicit method. The last two methods are unconditionally stable. The numerical results show that our methods have good accuracy.

分析表明，通过格式在不同时间层的交替，如分组显式方法、交替分组显式方法、交替分段显-隐方法，后两种方法是绝对稳定的，而且数值试验表明计算精度较好。

For accelerating this problem's compute time in parallel computer, we use Saul'yev type asymmetric different scheme and classicality explicit-implicit type to get a new alternating group explicit method for solving diffusion equation.

为便于在并行计算机上计算以加快计算速度，现将第二类saul'yev非对称格式以及古典显、隐式相结合，构造了求解扩散方程的一类交替分组显格式，其基本结构为四点组，并针对内点为偶数的情况，在节点两端点处进行了处理，以提高精度。

The development of Amanita manginiana in the study site, from sexual spores to mature sporocarps, might take more than one year.

According to the analogical experimental results, this approach has good properties of avoiding detection.

从算法的实验类比分析可以看出，算法具有良好的抗隐写分析性能。

Methods OPCAB were perfomed in 33 patients of left main with three-vessel coronary disease. The left internal mammary artery was used to be the graft vessel to anastomose with left anterior descending. The saphenous vein was used to be the graft vessel to anastomose with left circumflex coronary artery, right coronary artery/posterior descend artery, diagonal branch, obtuse marginal branch.

方法对33例左冠状动脉主干合并3支血管病变患者施行了OPCAB，用左乳内动脉作为移植血管与左前降支进行吻合，大隐静脉作为移植血管分别与回旋支、右冠状动脉/后降支、对角支和钝缘支进行吻合。

Based what mentioned before, in the background of Chinese traditional culture and poetic theory ,this thesis does an overall and precise analysis and research on five hot poetic topics: poetic prophecy, attitude towards being an official and being an anchoret, The Resurgence Of Tang Dynasty, qi xiang, philosophical art in notes written in Song Dynasty.

本文即立足于此，在中国传统文化及诗学理论的大背景下，对宋人笔记中诗谶、仕隐心态、《大唐中兴颂》、气象、理趣等五个诗学讨论热点，作了较为全面和细致的分析和研究。
