为分析引起导线粘连的因素及各种粘连因素的交互作用对导线粘连产生的影响,提出了基于响应面法的导线粘连因素交互作用分析。首先提出覆冰厚度、风速、档距、初始间距4种粘连因素并建立导线粘连数学模型;然后基于MATLAB迭代法,解出各因... 为分析引起导线粘连的因素及各种粘连因素的交互作用对导线粘连产生的影响,提出了基于响应面法的导线粘连因素交互作用分析。首先提出覆冰厚度、风速、档距、初始间距4种粘连因素并建立导线粘连数学模型;然后基于MATLAB迭代法,解出各因素在不同组合工况下对应的临界粘连电流值,最后基于方差分析法和响应面分析法,针对不同组合工况下的临界粘连电流值进行数值分析。分析结果表明,初始间距过小、档距过大是引起分裂导线发生粘连的最主要因素;初始间距越小、档距越大,导线越易发生粘连;两者的交互作用对导线粘连的影响极显著。 展开更多

In the present study, we aimed to assess the effect of combined estrogen cream on young girls’ labial adhesions, and to identify the possible factors affecting the treatment outcome. We retrospectively included 123 children with labial adhesions.Variables were collected, including treatment outcomes, conjugated estrogen usage, and dosage, whether it was combined with manual or surgical separation, whether to use erythromycin, and whether to be accompanied with vulvitis. Chi-square test, Fisher’s exact test, and t-test were used to analyze the correlation between influencing factors and treatment outcome in univariate analysis.We used logistic regression analysis to explore the key influencing factors. The use of conjugated estrogen in combination with manual or surgical separation(P = 0.001), and the degree of labial adhesions(P = 0.011) had significant effects on the final treatment outcome.The frequency of conjugated estrogen treatment, whether erythromycin was used in combination during treatment, and whether the children were accompanied by vulvitis had no significant effect on the treatment outcome(P > 0.05). After the logistic regression,we found that whether it was combined with manual or surgical separation(P = 0.000, OR = 0.078, 95% CI = 0.030–0.203), and the degree of labial adhesions in children(P = 0.003, OR = 5.324, 95% CI = 1.767–16.041) were independently related to the effect of conjugated estrogen treatment. The therapeutic effect of conjugated estrogen alone was better for mild adhesion. However,severe adhesions need to consider with manual or surgical separation in combination with conjugated estrogen treatment. It is not recommended to combine erythromycin with routine clinical treatment. Conjugated estrogen once a day can also achieve a good therapeutic effect. 展开更多
