We collected eight field data sets of potatoes farms in five years (2004~2008) from Taiwan Seed Improvement and Propagation Station. Besides, generalized linear models were employed to estimate the proportion of the individual plant infected. By mean square error as criteria. optimal group sizes were changed from 20 to 40 plants per group so that the cost was reduced and the testing process was improved efficiently. Not only can the group-testing design advance the accuracy of testing, but it can reach to the purpose of optimization.
本研究收集行政院农业委员会种苗改良繁殖场所栽种共5年(2004~2008)8个马铃薯用间试验资料,并应用广义线性摸式来估计单株马铃薯病毒病感染率,进而以均方误差为标准,来计算每群集最佳之植株数,结果显示可将原来每群集20株检测植株扩增至40株,这不仅能降低成本且不影响检测之精确度,可达到最佳化之目的。

Therefore, ammonium sulfate and PDMDAAC are selected as the dispersion medium and dispersant respectively, in order to obtain products with preferable fluidness. Studies show that, for ammonium sulfate, the optimum dosage is 27%-29%, and PDMDAAC is 10%-18%.
故选择硫酸铵与PDMDAAC分别作为盐水介质中CPAM分散聚合的分散介质与分散剂,并确定了硫酸铵最佳用量为聚合体系质量的27%~29%,PDMDAAC最佳用量为单体质量的10%~18%,该条件下制得的产品具有较好的流动性。

The results showed as follows: 1 Extraction of gelsemium total alkaloids. Total alkaloids were extracted with 95 per cent ethanol. The extract rate was 0.519 per cent and the extract purity were 88.02 per cent and 87.38 per cent; Total alkaloids were extracted with chloroform .The extract rate was 0.416 per cent and the extract purity were 89.02 per cent and 94.52 per cent. 2 Isolation of gelsemium total alkaloids with TLC. Total alkaloids contained five or more alkaloids. The optimal developing agent was chloroform :methanol :ethyl acetate(9:l:0.3),the optimal eluent was methylene chloride:methanol(92:8). 3 Isolation of total alkaloids with column chromatography. Alkaloid A and alkaloid B were obtained, alkaloid B was identified as koumine.
