负责火星的一个低轨道空间站的设计。为简化结构，该空间站由一系列密闭的立方体（airtight cubical modules ACM）组成，这些ACM曾连接在一起。困扰你的一个问题是致命的病菌也许留在火星的上层大气中。因为空间站有时需要在上层大气中飞行，所以急需在ACM的各个接触面进行额外的防护，无论是边对边还是面对面，连接是密闭的，所以没有细菌能够进入。一个ACM与另外一个ACM共享的面不需要防护。如果在每个ACM每个面上都加防护，花费巨大。因此，需要知道ACM额外防护的确切面数目(Responsible for the design of a low-orbit space station on Mars. In order to simplify the structure of the space station by a series of closed cubes (airtight cubical modules ACM) composed of these ACM had together. One problem is bothering you deadly germs might stay in the upper atmosphere of Mars. Because the station is sometimes necessary to fly in the upper atmosphere, so urgently needed in all contact surfaces of the ACM additional protection, either face to face or side-to-side, the connection is closed, so no bacteria can enter. An ACM ACM shared with another surface does not need protection. If you have added protection on each side of each ACM, costly. Therefore, the need to know the exact number of additional surface protection ACM)

本文详细介绍了如何实现VC与Matlab的混合编程，对于进行复杂的运算有很好的用处(This paper describes how the VC and Matlab programming mix, for complex calculations to good use)

利用LFSR生成伪随机序列（m序列） 对待隐藏的图像进行加密然后利用线性插值的方法隐藏于载体图像中。 代码很完整 用的是MATLAB7.0(Use LFSR to generate pseudo-random sequence (m sequence) to treat encryption to hide the image and then use linear interpolation method of hidden images in the vector. Complete code is used in MATLAB7.0)

在分析结构损伤后，给结构添加噪声，再对结构不同损伤情况下的分析(After the analysis of structural damage to the structure adding noise, and then the structure is different in case of damage)

上电后,在BRAKE信号无效,且保护逻辑无输出的情况下? 电机按DIRECTION信号的方向转动? 电流传感放大器采样电机电枢电流,经13脚的RC网络转换为电压值,与D/A转换输出的预定阀值相比较。如果当前的电流使转换的电压值小于阀值?(Power after the BRAKE signal is invalid, and the protection logic no circumstances ? electrical output signals according to the direction of rotation DIRECTION ? current sensing amplifiers motor armature current sample by 13 feet of RC network is converted to voltage value, and D/A conversion output compared to the target threshold. If the current of current to voltage conversion value is less than threshold ?)
