The theory of stack technique of variable binning comes from definition of first Fresnel Zone .

变面元叠加技术的理论基础来源于第一菲涅耳带定义，据此，可以随深度增加进行扩大面元处理，以增加同一CMP道集内的叠加道数，达到增强有效波能量且消除各类干扰波的目的。

This study conducted a secondary data analysis based on the data from 1999 Survey of Health and Living Status of the Middle Aged and the Elderly in Taiwan, provided by the Bureau of Health Promotion, Department of Health, R.O.C.. The study subjects were elders over 65 years old, and the number of valid samples was 2890. The data were analyzed with descriptive statistics, one-way ANOVA, Chi-square test(X2), Independent-Samples t-test, point biserial correlation, the Pearson product-moment correlation, logistic regression analysis, multiple regression analysis and hierarchical regression analysis.
