扩散系统之浓度分布的装置。管中储放静止液体B，高度为L=10 ㎝，放置于充满A 气体的 环境中。假设与B 液体接触面之浓度为3 C 0 0.01mol m A = ，且此浓度不随时间改变 而改变，即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为 D m s AB = 2×10− 9 2 。试决定以下两种情况下，气体A溶于液体B中之流通量(flux)。 (a) A 与B 不发生反应； (b) A 与B 发生以下之反应 A+ B→C ， A A − r = kC 其反应速率常数k = 2×10− 7 s− 1。 (Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)

Statistical Analysis Practice Problems

基于matlab的汽车驱动力阻力平衡设计。可用于检测汽车的总体设计是否满足要求。(Matlab car driving force resistance balanced design. The overall design may be used to detect whether the vehicle meets the requirements.)

XCODE超级玛丽，部分oc，部分c++(SuperMario，made by xcode)

说明：  matlab LSB信息隐藏技术GUI控制台（包括隐藏图片和文字和图像置乱功能）(Matlab LSB information hiding technology GUI console (including hiding picture and text and image scrambling function))

说明：  关于matlab与digital signal的几个源程序。具体内容请自己下载看！(on Matlab and several digital signal source. Specific details please download Look!)
