[ELanguage] cifafenxi DL : 0: 简单词法分析器构造在开始状态，首先要读进一个字符。若读入的是一个空格（包括blank,tab,newline）就跳过它，再继续读字符，直到读进一个非空字符为止。在标识符状态，识别并组合出一个标识符之后，还必须加入一些动作，以便查保留字表，确定识别出的单词符号是保留字，还是用户自定义标识符，并输出相应的记号。在无符号数状态，可识别出各种常数，包括整数在内。在组数的同时，还要做从十进制数到二进制数的转换。 -A simple lexical analyzer constructed at the beginning of the state, first of all to read into a character. If the read is a space (including the blank, tab, newline) will skip it, and then continue to read characters until the time into a non-empty character so far. In the identifier state, to identify and assemble an identifier, you must also add some actions in order to check a reserved word table to determine the identify of the word symbols are reserved words, or user-defined identifier, and output the corresponding symbol. In the unsigned status, can identify a variety of constants, including the integer included. In the group number, we must also do a number from decimal to binary number conversion.

[ELanguage] 344556775444 DL : 0: 跟踪问题本质上是一个混合系统的状态估计问题[38】，即利用传感器的离散观测来估计所感兴趣区域内目标个数和状态的过程，其中目标状态包括运动分量 (位置、速度、加速度)和属性信息(信噪比、谱特征，身份信息等)。目标跟踪问题根据跟踪环境的不同可以分为单机动目标跟踪和多机动目标跟踪。-Tracking is essentially a hybrid system of the state estimation problem [38】, namely the use of sensors to estimate the discrete observation target region of interest number and status of the process, which includes movement component target state (position, velocity, acceleration) and attribute information (signal to noise ratio, spectral characteristics, status information, etc.). Target tracking problem based on tracking the environment can be divided into single-target tracking, and multi-target tracking.
