数值计算方法在C语言中的应用 介绍了数值计算方法与计算机程序语言相结合的重要性，在给出牛顿迭代公式之后，阐述了牛顿迭代法在do-while循环中的应用，然后通过实例基于曲线梯形面积求解方法，论述了矩形法和梯形法在for循环中的应用．最后指出：用正确的数值计算方法编写高效的计算机程序解决复杂的实际问题应成为当代理工科大学生必备的基础与技能-numerical calculation method in the C language to the application of numerical methods and computer programming language combined weight in particular, given the Newton iterative formula, explained Newton iteration in do-while loop, the application Then examples curve trapezoid area based solution discussed rectangular and trapezoidal method for the application cycle. Finally : with the correct numerical method to prepare efficient computer programs to solve complex practical problems should become contemporary science and engineering students essential infrastructure and skills

讲述“软件开发”和“做程序员”的道理，视野独特，构思新颖，内容风趣，不落窠臼，令人耳目一新。堪称难得，以至回味无穷。-on "software development" and "do programmers", the unique vision, the novel as a sense of humor, have an original style. refreshing. His rare, as well as the countryside.

DirectX Lighting vs. Real World Lighting （DX光照 对 真实世界光照） 在DX中，我们能创建不同类型的光，使场景看起来更真实。但要记住，DX中的光只是在近似地模拟自然界的光。在自然界中，光由光源（如灯泡）发出，然后延直线传播，直到消耗完毕或传入眼睛；光在遇到物体时会发生反射，每次反射都会有能量的消耗；实际上，光可以在物体间反射千百万次，而且光滑表面会比不光滑的表面反射更多的光。这一切如果全算进来的话，计算量是巨大的，所以，DX只是在近似地模仿。 -DirectX Lighting vs. Real World Lighting (DX light illumination of the real world) in the DX, we can create different types of light, to make scenes look more realistic. Bear in mind, however, DX in the light only in the approximation to simulate natural light. In nature, light from light source (such as light bulbs) to issue, and then the extension of a straight line, until the consumption of finished or imported into the eyes-ray object in the face of reflection will occur, each reflection will have energy consumption in fact, light can be inter-reflection in the object of millions of times, and the smooth surface than the non-smooth surface reflects more light. All full-count in. If so, computation is enormous, so, DX only approximate
