Based on the threshold idea of threshold regression model, the threshold factors and threshold values are introduced and determined by the correlation analysis method of best curve fitted in conventional regression model 借鉴门限自回归模型的门限思想,在常规回归模型中引入门限因子和门限值,利用提出的最佳拟合相关分析法确定门限因子和门限值,建立了门限回归模型。
Based on observation data at the meteorological source and geological status at different regions from hubei province, together with experimental researches at conjac biological characteristics, osculating value method at multi-objective decision a well a gray correlation analysis method wean employed to design the planting area distribution 摘要利用湖北省各区地理气候资源的统计资料,结合魔芋生长发育的生物学特性的试验观察,利用多目标决策密切值分析法和灰色关联分析法,对湖北省魔芋种植区域进行了规划。
In order to remedy the faults of the traditional pipe-leak detector based on the straight-correlation analysis method which has high demand for hardware and high price, the pipe-leak detector based on the polarity correlation algorithm with the cross-zero method is presented, the hardware design and the test is finished, the result only with the error from 1 % to 3 % is gained, and its feasibility is testifies 针对采用直接相关法的传统相关测漏仪对硬件要求高、价格较贵的缺点,将极性相关的过零算法应用于相关测漏,并设计了硬件结构,进行了实验仿真,在实验室条件下,测量误差约为1%~3%,验证了其可行性。
Consulting criterion and experts ’ experience the grade standards of indexes are listed, and applying grey correlation analysis method to calculate value of the indexes, of which the form is a serial data . the last, an actual bridge uses synthesis evaluation model, of which calculating result is the same as conclusion of the experts . so the bridge condition synthesis evaluation model of this dissertation is relatively in reason; chapter 3 discusses defects of current bridge condition evaluation methods, and analyzes various factors, which bring bridge degeneration 参考《公路桥涵养护规范》中的分级标准进行评语量化,最后根据综合评价模型进行实桥的评价,验证本文所用方法的合理性;第三章,讨论层次分析法建立桥梁评价模型存在的问题,分析影响桥梁退化的各种因素,并给出因素的模糊分级标准,运用模糊综合评判方法估算桥梁平均退化率,以掌握桥梁的退化状态,并举例说明本方法的可行性;第四章,针对桥梁状态评价具有信息不完全、关系不明确等灰色特性,以及目前我国桥梁管理部门储备的桥梁数据资料较少的弱点,对桥梁状态退化趋势的预测采用灰色预测的方法,并给出了桥梁状态的灰色马尔可夫预测模型和非等时距灰色预测模型。
The objectives of this paper were : ( 1 ) quantitative analysis on agricultural development status in ansai county during 1995-2002 period; ( 2 ) exploration of dynamic variation and direction of rural industry structure adjustment by using the gray correlation analysis method; ( 3 ) discussion impacts of " grain for green project " on agriculture and rural economics development in the loess hilly and gully area, and the project's sustainable 本文依据1995-2002年安塞县统计资料和农户调查数据,在对安塞县实施退耕还林工程以来农业发展状况进行定量分析的基础上,运用灰色关联度分析法,分析确定安塞县农村产业结构调整的动态变化过程和农业结构调整的方向,以探讨退耕还林还草的实施对黄土丘陵沟壑区农业与农村经济发展的影响,以及退耕还林工程的持续性。
The application of the b-spline wavelet analysis method to series of climate and external forcing factors is introduced . using lag-correlation analysis method, interpretative variances analysis method, phrase comparing method to the wavelet analysis result, we not only gained the variation at different scales of the global temperature and el nino signals, the location of the jump points and latent scale of these series, but also indicated the magnitude, extent of the effect of external forcing factors on them 利用小波分析方法,辅之以滞后相关分析解释方差分析及位相对应比较方法,得到了气温变化及enso活动在各尺度层次上的变化,突变点位置及特征尺度,并确定了太阳活动火山活动和温室效应等外强迫因子对气温及enso的影响尺度幅度及响应时间。
