阻塞函数在完成其指定的任务以前不允许程序调用另一个函数。例如，程序执行一个读数据的函数调用时，在此函数完成读操作以前将不会执行下一程序语句。当服务器运行到accept语句时，而没有客户连接服务请求到来，服务器就会停止在accept语句上等待连接服务请求的到来。这种情况称为阻塞（blocking）。而非阻塞操作则可以立即完成。比如，如果你希望服务器仅仅注意检查是否有客户在等待连接，有就接受连接，否则就继续做其他事情，则可以通过将Socket设置为非阻塞方式来实现。非阻塞socket在没有客户在等待时就使accept调用立即返回

关于湍流仿真的经典文献，对气象雷达和流体力学专业等相关专业的人士非常有参考价值。(The standard k-E. equations and other turbulence corrections are evaluated and reported with respect to their applicability in three-dimensional flows. The turbulence models are formulated on the assumption that an ilsotropic eddy viscosity and the modified Boussinesq hypothesis adequately describe the stress distributions, and that the source of predictive error is a consequence of the modeled terms in the ke equations. Turbulence model corrections are incorporated to investigate their impact on these errors. Predictions from various turb+lence models are compared with experimental data froq an isothermal 3-D configuration. The data combsons delineate the relative advantages and disadvantages of various modifications. The k-E model perfbrms competitively with other model corrections and in some instances is judged to be superior than the modzfied treatments. However, given the additional computational time and the marginal superiorityofthe investigated models, it is )
