time demand造句
例句与造句
- the paper proves that with ar ( 1 ) process for the end demand, if retailer adopts moving average or exponential smoothing to forecast the non-zero lead time demand, then bullwhip effect in demand forecasting and processing will occur; if retailer adopts the optimal forecasting method, then bullwhip effect will occur conditionally
证明当存在订货提前期时，零售商采用移动平均法及一次指数平滑法预测会导致在需求预测，信息处理及传递过程中产生牛鞭效应；而采用最优预测仅在需求相关性很强时存在有限值的牛鞭效应。 - the recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real-time demands . the reserch shows deficiency existed in the prevenient principle of transient current protection, so a new improved scheme of transient current protection is proposed . the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis . the study shows that operate of transient protection is correct when the bus distribution capacitance change . other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated, because the trip is incorrect at this time; the features of transient current and it's energy is different between the fault and thunder over-voltage in transimission line, and them can be identified; the ratio of high frequency component of current in serise capaciters compensation line, svc and hvdc system is far little than fault transient current, so all of them do not affect the working of trasient current protection
应用功率谱估计方法讨论了故障高频暂态噪声信号在频率轴上的分布情况，利用功率谱分析结果实现的非参数化系统辨识方法研究了母线分布电容对电流高频暂态信号的衰减特性。论文的后半部分(第五,六,七章)着重分析了现有基于故障电流的暂态保护原理和判据存在的问题，提出了新的实现方案，并讨论了暂态电流保护的运行性能。利用多分辨分析和小波分解快速算法构成的递推暂态保护判据，可以准确区分故障线路和非故障线路，实现超高速暂态电流保护，计算更为简单方便，计算速度更快。 - the paper ’ s main works are as follow : ( 1 ) several methods of getting pitch period are researched in details . according to the real-time demand for the systems, the methods for pitch searching are simplified as follow : after searching the peak value point every third point within pitch range, search the peak value point every point near the current peak value point
(1)研究了基音周期的求取方法,并根据系统的实时要求,将逐点搜索基音周期的方法简化为粗细法,即在基音周期范围内隔点搜索相关函数最大峰值点,然后在此时得到的最大峰值点附近继续搜索,将最后得到的峰值点作为基音周期值。 - then in pre-processing stage, for the allowance of the real time demand, we dispose the method of hough transform and apply linear fitting to determine the border of paper currency to achieve localization and adjustment directly . by the analysis of based directional block feature extraction, we propose a new method of feature extraction based on geometry distance . in the design of classifier, we use the lvq network to classify the feature and introduce a classifier with two layers
在图像的预处理中,由于系统对纸币处理实时性的要求,该过程必须在很短时间内完成,因此我们对图像的边界检测,撇弃了诸如图像二值化,hough变换等处理手段,而是直接采用分段线性拟合的方法确定图像中纸币的四个边界,以完成纸币的定位和倾斜矫正。 - It's difficult to find time demand in a sentence. 用time demand造句挺难的
