Such impressions ramify very widely, and masque themselves very subtly, in historical works written in the modern fashion; but I find the trace of their presence in the domain of jurisprudence in the praise which is frequently bestowed on the little apologue of Montesquieu concerning the Troglodytes, inserted in the Lettres Persanes.

例如，在荷马文学中，优烈锡士的欺诈狡猾，好象是和纳斯佗的智虑明达、海克佗的坚毅不拔以及亚济里斯的英雄豪侠处于同等的一种美德。

The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming. Robust H〓 apriori filtering and robust apriori L〓 filtering in discrete-time system are subject to a nonconvex constraint.

对这些滤波问题解法的改进同连续系统下的情况基本类似，对确定性系统的H〓验前滤波和验后滤波，本文解法可直接得出最优滤波问题的解；对H〓约束下的L〓验前滤波及验后滤波，其解可归结为一凸优化问题；但不确定性系统H〓验前滤波和鲁棒L〓验前滤波的LMI解法中有了非凸约束，因此要用迭代法求解。

Research results show that 25% Amistar SC could be used safely on Fuji, New Red Star, Beidou, Australian Green Apple, but it is harmful to Gala. Amistar has a great control effect on apple powdery mildew, apple scab and apple Alternaria leaf spot. The control effect works from 80% to 90% when it is used with 1:2000 to 1:3000 dilutions in field.

结果表明，25% Amistar SC除对嘎啦品种有药害外，对红富士、新红星、北斗、澳州青苹等6个骨干品种均无任何不良影响，使用安全；同时，25%阿米西达SC对苹果白粉病、黑星病及斑点落叶病等3种主要病害均具有显著防治效果，使用浓度1：2000~1：2500，防治效果为80%~90%；在广谱性和防效上显著优於目前生产上推广的常规性的苯并咪唑类、三唑类及代森类的杀菌剂品种。

First, in the composite hypothesis testing, circular dispersion error which is more practicable than horizontal and vertical error is used to discuss some problems of the dispersion of impact points; and the critical area of decision in the dispersion problem is analyzed; the specific expression of Bayesian risk is worked out, which ameliorates the method that only can get the approximate solution by calculating numerical integration.

由此，本文主要应用Bayes方法对以下几方面进行了探讨：首先，在复杂假设下，本文利用圆散布误差这一精度指标对落点散布鉴定问题进行研究，它比以往所用的纵、横向偏差精度指标更具现实意义；分析了此鉴定问题的决策临界区域；给出其Bayes风险的具体表达式，对用数值积分进行近似求解的方法进行了改进；在此基础上，通过极小化试验的风险确定最优试验数n，并讨论了决策中犯两类错误的概率，给出了验前信息的表示。
