Base on the data collected from the field investigations , we analyzed the static life table , age structure , spatial distribution patterns of the populations of e . chloranthoides . we further studied the intraspecific competitions within the species and the interspecific competitions between the species and other concomitant species in the communities . with the helps of the logistic equation , leslie ' s matrix and the average moving law method we simulated and estimated the population dynamics of this endangered plant species 本研究以缙云卫矛为研究对象，通过对三个种群的野外调查，研究和分析了缙云卫矛的种群年龄结构、种群空间分布格局及种内和种间的竞争关系，并利用logistic方程、 leslie矩阵及移动平均法模拟和预测了三个种群的数量和结构动态，在此基础上分析了造成缙云卫矛濒危的原因，提出了相应的保护措施，旨在为缙云卫矛的保护提供理论依据。
Connecting with moving average line , which is usually used by investors , we established three strategy models . computer program simulating results have shown that the three constructed strategy action would provide investors " decision - making with assistance information , and among those , the third strategy action are the optimum strategy 结合投资者常用的指标移动平均线，建立了三个策略模型，计算机模拟结果显示建立的三个策略模型都能对投资者进行投资决策提高较大的帮助，在这其中第三个策略行动的行动是最优的。
On the stage of process control , analyzing characters of six sigma process , we take the successive elgibles as controlling objects , and give the judgement principles of stable and abnormal process . on this base , we introduce a new control chart - ewma control chart based on successive elgibles to control the tiny variable . finally , in this paper , we discuss how to control six sigma process through the combination of pci and ppl 过程控制阶段，分析了6质量过程的特点，以不合格品间连续合格品数作为控制对象，并给出了过程的判异和判稳准则；在此基础上，引入了连续合格品数指数加权移动平均控制图来控制过程的微小波动；最后还对如何联合运用过程能力指数和过程性能指数来控制过程进行了分析。
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。
With the pressure measurement system for the swirl chamber diesel engine , by using the methods of equivalent power and the seven point three degree average for the indicator diagram , we can correct the tdc , smooth the pressure curve and make more accurate pressure data that is a well basis for the calculation of combustion heat release rate 摘要本文在自行开发的涡流室柴油机压力数据测录系统的基础上，利用等效功法和七点三次加权移动平均法，分别对示功图进行了上止点校正和压力曲线光顺，使压力数据更精确，为燃烧放热率的计算打下了良好的基础。
This part mainly discusses the statistical distribution of the price and the returns rate , including random process and the returns rate model , gaussian process , measuring returns rate with discrete random process , white noise process , auto regression process , moving average process , auto regression moving average process , random walk , continuous random process , leptokurtic distribution , conditional mixed distribution , garch model and fractal distribution 在这一部分中，我们主要讨论价格和收益率的统计分布：随机过程和收益率模型、高斯过程、收益率计量中的离散随机过程、白噪声过程、自回归过程、移动平均过程、自回归移动平均过程、随机行走、连续随机过程、尖峰分布、条件混合分布、 garch模型以及分形分布。
