查询词典 by estimate

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。

Firstly, by constructing the Lyapunov function with a special structure, a prior estimate is obtained. Secondly, with the help of Green\'s function, the original problem is transformed into an equivalent operator equation, and the fixed point theory of contraction mapping in a Banach space guarantees the existence and uniqueness of the global solution.

首先，构造具有特殊结构的Lyapunov函数，得到解的先验估计；其次，借助Green函数将原方程等价变换成算子方程，Banach压缩映射的不动点定理保证了全局解的存在唯一性；最后通过常微分方程的定解，证明了主要结论，即平凡解全局渐近稳定。
