As the memory management functions self-offered by VxWorks which use first fit algorithm can not satisfy the demands of strict timeliness and efficiency of memory management in the communication applications of software, to solve the problem, a new realizing method of memory management was advanced for the software development platform based on VxWorks using two completely independent memory pool sets—one for process communication, and the other for the applications, with the platform directly managing the ...

因VxWorks自身提供的内存管理函数采用first-fit算法，不能满足通信应用领域软件对内存管理的高实时性和内存利用率的要求，为了解决该问题，基于VxWorks软件开发平台给出新的内存管理实现方法：采用两套完全独立的内存池集——进程通信内存池集和应用内存池集，平台直接管理内存，为整个系统提供高效的动态内存管理机制，使新定义的内存管理模块更适合通信产品应用领域的嵌入式软件开发。

Pure magnesium was treated by A. C. treatment technique in 0.25mol/L NaZSO4+0.1mol/L NAOH solution. The surface morphology was observed by scanning electron microscopy. The contact angle of the treated surface of pure Mg was measured by the First Ten Angstroms instrument and then its surface free energy can be calculated. The effect of alternating current treatment on the corrosion resistance of the pure magnesium was studied through electrochemical methods in 0.05mol/L NACI+0.01mol/L NAOH solution. The experimental results showed that a uniform and perfect oxide film was formed after A.

采用载波处理方法，用0.25mol/L Na2SO4+0.1mol/L NAOH作为载波处理溶液，对纯镁试样进行载波处理，通过正交试验确定载波处理的最佳工艺参数；用扫描电了显微镜观察载波处理后试样的表面形貌；用First Ten Angstroms仪器测量蒸馏水纯镁的接触角并计算出表面能；用电化学方法研究了在0.05 mol/L NACI+0.01mol/L NAOH溶液中载波处理对纯镁耐蚀性能的影响。
