基于Matlab对约瑟夫森结（Josephson Junction）RCSJ模型的交直流I-V特性及非线性混沌现象进行数值模拟。通过计算机数值模拟得到该模型的非线性微分方程数值解，研究了RCSJ模型中各参量对约瑟夫森结的影响，进而简要分析其I-V特性和非线性混沌现象的产生机理，绘制出约瑟夫森结的交直流I-V特性曲线、非线性微分方程的相图及因其高度非线性而引起的通过倍周期分岔和阵发性原理进入混沌状态的分岔图。还给出庞加莱截面及功率谱。(Matlab based on the Josephson junction (Josephson Junction) RCSJ model AC and DC IV characteristics and non-linear numerical simulation of chaotic phenomena. Through computer simulation model by the numerical solution of nonlinear differential equations to study the RCSJ model parameters on the impact of Josephson junction, and a brief analysis of the IV characteristics and the emergence of the phenomenon of non-linear chaotic mechanism, drawn Josephson junction IV characteristic curve of AC-DC, non-linear differential equations and the phase diagram because of its highly nonlinear arising through period-doubling bifurcation and chaotic state of paroxysmal principle of access to the bifurcation diagram. Poincare cross-section and was also given power spectrum.)

关于蝶形宽带微带天线的设计
索引：蝶形宽带微带天线. 设计方案 排列效率
摘要：现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低，是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分，然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6％
(One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects.)

Matlab_Help_Translate
The purpose of this code is to use GOOGLE translate to translate help of a command in MATLAB
( This code is written by M.A. (aka lftx).
The purpose of this code is to use GOOGLE translate to
translate help of a command in MATLAB to Turkish (you can modify it).
So do not expect much.
You need an active internet connection for this function to work
The function uses a java package to use GOOGLE translate s API
which is not developed by me, for detailed description of the java
files you can check
http://code.google.com/p/google-api-translate-java/
the usage of the file is very similar to the original "help" function
and if you add the files to your matlab s path you can use it as you use
MATLAB "help" function
EXAMPLES: helptr eye
EXAMPLES: helptr( why ) or helptr why
The function has been working as of DEC 2010
I cannot guarantee that it would be working in the future, as google might
change its API, or might not like your referring webpage or maybe your IP.
