例句与用法
- With the similar technique , they gave a complete description of the connectivity and the totally disconnectivity of the julia sets of cubic polynomials
他们用类似的拼图技巧，对三次多项式的julia集的连通性和完全不连通性作出了完整的描述。 - Based on the historical data of shanghai port container throughput , forecast models are established by using grey prediction model and cubic polynomial curve prediction model
摘要利用上海港国际集装箱吞吐量的历史数据，分别采用灰色预测法和三次多项式曲线模型建立了单项预测模型。 - In order to obtain a high - quality speech codec , the phase information of speech should be included in codec . in this thesis , a method for quantizing the phase of sew ( slowly evolving waveform ) and reconstructing sew ’ s phase with cubic polynomial interpolation is given based on the perceptual weighting analysis - by - synthesis ( a - b - s ) vector quantizer for the phase spectrum in wi coder
本文基于感觉加权相位谱分析合成( abs - analysis - by - synthesis )矢量量化方法,给出了一种wi编码器中慢渐变波形( sew - slowlyevolvingwaveform )的相位信息量化及合成端相位的三次多项式插值重建方法。 - The methodology adopted by most existing cam / cnc systems , which uses huge amount of linear segments to approach the original shape and make linear interposition increases the cost of memory size and communication work of the cnc system tremendously . a new approach based on cubic polynomial and b spline interposition to rebuild the cam generated tool path under real time condition is presented in the paper . applications on cnc machine tools showed that the presented approach improves the machining accuracy and increases the cutting speed significantly
目前大多数cam / cnc系统采用大量小直线段逼近原始曲线和直线插补的做法，只能获得零阶连续的走刀轨迹，逼近精度低，不能保证高速加工运动的平稳性，因而加工精度、光洁度和加工速度都难以提高；由小直线段构成的nc代码数据量庞大，也增加了数控系统在内存容量和数据传输方面的成本。
