constant error meaning in English
常在误差。
Examples
- Calibration constant error and function for gyro - compass on sea trial
航行试验中电罗经固定误差校正和效用试验。 - The relation of radius of curvature and error as well as formulas of increasing parameters on condition of constant error are diverted . the equation of the line on the center of approximate circular arc is obtained ， and it can avoids the trouble that numerical solution owns possibility of no convergence and simplifies node calculation of non - circular curve
导出了曲率半径与逼近误差之间的关系和等误差条件下的参数递推公式，建立了通过逼近圆弧圆心的直线方程和圆心坐标计算公式.按这种方法用圆弧逼近平面参数曲线，不需要求解非线性方程组，避免了计算可能不收敛的麻烦，简化了非圆曲线的节点计算过程 - On the base of researching the theory of the scheme and analyzing the signal feature , it is obtained that the existence manners and character of distance information in the differential frequency signal . at the same time , a new conclusion is gained that the technology of frequency agility can decrease the constant error of system . it is also to say that frequency agility and frequency modulation fixed - distance fuze has the similar feature to random period frequency modulation fixed - distance fuze . according to the theory of address coding in the hopping - frequency communication , the paper presents the principle of selecting the frequency agility sequence which fit to the radio fuze and constructs the frequency agility sequence family based on the rs codes
在深入研究方案原理和分析信号特征的基础上，获得了该体制引信差频信号中，距离信息的存在形式和特点，得出了频率捷变技术的引入降低了系统定距固定误差这一新的结论，即频率捷变调频定距引信在定距性能上具有类似随机周期调频定距的特征。本文引入跳频通信地址编码理论，结合无线电引信的具体特征，提出了适用于无线电引信的频率捷变序列的选择原则，并构造了基于rs码的宽间隔频率捷变序列族。
