But an abstract mathematical description ( like the one I just gave) does not really illustrate what use a state machine might serve in practical programming problems. 但一个抽象的数学描述(就像我刚给出的)并不能真正说明在什么情况下使用状态机可以解决实际编程问题。
Abstract It introduces the mathematical principle and development essentials of the universal project lofting system, based on which the universal lofting system in view of pocket machine is developed for port engineering and good effect is achieved, realizing lofting without office work. 论述了适用于各种工程的通用放样系统的数学原理及其开发要点,在此基础上,开发了基于袖珍机的通用放样系统应用于港口工程,收到了良好的效果,实现了无内业放样。
