Cronbach a of them equals respectively 1.000, 0.714. Conclusions The system could form the test pater with the strategy of the combination of the certain proportion of the important degree and the binominal distribution models which realized the Internet testing, rectifying and analysis.The test papers abstracted from the system were reliable and valid. It can scientificly, objectively evaluate the students' ability and it's beneficial to deviation of the teaching, testing and controlling testing cheat. The Non-paper testing system has good practical value.

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.

Based on the absorbance change of indicators with the concentration of hydrogen ion released from the enzyme-catalyzed reaction, a convenient colorimetry method is established for the assay of acidic phospholipase 〓 and glycogen phosphorylase b Brilliant yellow and bromothymol blue are chosen as indicators for assays of acidic phospholipase 〓 and glycogen phosphorylase b by following the absorbance changes at 495 nm and 615nm respectively The method is simple, sample-saving, sensitive and valid for a wide range of enzyme concentrations.

为了研究糖原磷酸化酶的激活动力学和酸性磷脂酶〓的复性过程，我们根据酶催化反应中释放氢离子浓度的变化引起相应的指示剂的光吸收发生变化的原理，建立了一种简捷的比色法，用于测定酸性磷脂酶〓和糖原磷酸化酶b的活性。选用亮黄和溴麝香草酚兰分别作为酸性磷脂酶〓和糖原磷酸化酶b测活的指示剂，在495 nm和615 nm处检测二者的光吸收值的变化，可以测定酶活。本方法的优点是，可在比较宽的酶浓度范围内进行活力测定，而且操作简单、节省样品、灵敏度高。
