AcrSde 空间数据库引擎. 很好的东西发给大家共享！-AcrSde spatial database engine. Good things to share!

应用背景有很多方法可以看到项目之间的相似性。这些都是属于一般保护伞下的技术。这种技术的结果，简单来说，就是一套可以被理解为“如果这个，然后，”的规则；想象一下你坐在桌子上的10000张收据。每一个收据都代表一项交易，购买的物品。收据是一种代表性的东西，走进了客户的篮子，因此“市场篮分析”。这正是食品杂货的数据集包含的：一个集合的收据，每行1个收据和购买的物品。每一行被称为“交易”，并且每一行都代表一个项目；关键技术支持：我们的项目集发生在我们的数据集的馏分。信任：一个规则是正确的一个新的交易与项目在左边的概率。电梯：一个规则的信心超过了预期的信心；

In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.[1] The implementation of threads and processes differs between operating systems, but in most cases a thread is a component of a process.

非常经典的C++程序，十分实用对于练习程序来说。(good programme)

人体生命曲线 根据科学理论，每个人都有一个生物钟，生物钟的运动直接影响到人的智力、体力和情绪的变化，三者呈正弦曲线分布，并且按各自不同的周期运动。正确掌握自己的生物钟，把握好自己智力 、体力和情绪的最佳状态，将有助于您的工作、学习和健康。-human life curve based on scientific theory, each person has a biological clock, the circadian clock directly affect the movement of the intellectual, physical and emotional changes, the three were sinusoidal curve distribution, in accordance with their respective campaign cycle. Correct use of the biological clock, a good grasp of their intellectual, physical and emotional best, will help your work, learning and health.

只要有这两样配套替换使用！问题完美解决！直接替换授权文件是不行的！因为这个新的授权文件不支持以前的老端！必须配套！(China, Portugal pledge to jointly push forward construction of Belt and Road The China-Portugal relations are entering the best period in history and presented with new opportunities for development, Xi said.
