鉴定试验

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。

Methods Germ tube test, chlamydospore test, CHROMagar Candida and API20 kit system were applied to separate non-Candida albicans strains from Candida albicans. Then PCR was used to amplify the internal transcribed spacer region of ribosomal DNA from 4 species of common Pathogenic non-Candida albicans (Candida glabrata, Candida parapsilosis, Candida krusei and Candida tropicalis), and the products were digested with the two restriction endonucleases (Msp Ⅰ and Hae Ⅲ) respectively. Results The four isolates consisted of 15 strains of Candida glabrata (7.50%), 7 strains of Candida parapsilosis (3.50%), 5 strains of Candida krusei (2.50%), 2 strains of Candida tropicalis (1.00%).
