A sample of 480 Chinese adolescents and 115 juvie aged 13-18 was investigated with series of Chinese transitions of measures, including the revised Ego Identity Status Questionnaire(EOMEIS-2) and Adolescent's Social Adaptive Behaviors Questionnaire. Results indica ted:1. For the adolescents, the distributions of ego identity statuses, whether in the ideological, interpersonal or total domain, are unbalanced.

首先，通过问卷预测，对问卷进行修订和信效度的检验，再以修订后的问卷正式施测，然后运用卡方检验和方差分析探讨同一性状态和社会适应性行为的发展特征，最后通过方差分析考察同一性状态和社会适应性行为的各个层面的关系。

Firstly, normal mice was given orally by SM(qd×2d), and the dysbacteriosis were caused in them ,and then they were given orally by STM,these mice were formed experimental salmonellosis models ,finally these salmonellosis models were treated by bifidobacterium ,and count respectively the cfu/g of STM number in the mice excrement during different time of therapy,detect the index numbers of liver and spleen respectively, detect content of TNF-a in blood and in spleen respectively.

先用硫酸链霉素给正常小鼠灌胃2d，出现菌群失调症状，再用STM灌胃造成小鼠STM感染，使用两岐双岐杆菌液干预治疗STM感染小鼠，检测不同治疗时间各组小鼠粪便STM菌落数、肝脾指数、血及脾中TNF-a的含量。采用SPSS12.0统计软件包进行数据处理分析，统计学方法采用双因素重复测量资料的方差分析、单因素随机化设计的方差分析、卡方检验、多组均数比较的非参数秩和检验。结果：随着治疗天数的增加，STM菌落数逐渐减少，未干预组、生理盐水组及双歧杆菌组比较结果均为P＜0.01；组间比较，双歧杆菌组STM数下降最快。

Acquired conclusion was that the sample mean value submitted to normal distribution, and the sample variance was composed of a number of linear sum of random variable submitted to Chi-Squared distr.

得出的结论是：样本均值服从正态分布，样本方差由若干个服从卡方分布的随机变量的线性之和组成；样本均值的期望等于各管落点期望的算术平均值，方差为各管方差的算术平均值；样本方差是各管落点总体平均方差的无偏估计，方差与各管落点散布的差异相关；样本均值与方差相互独立的充要条件是：各管落点属于独立同分布样本。

Result 1-3-β-D glucosan was found exceeding the diagnostic criteria (10pg/ml) of the kit in 18 cases of fungal rhinosinusitis; and it was found no more than 10pg/ml in all 5 cases of purely nasal septum deviation patients. One of the 18 cases of fungal rhinosinusitis patients is chronic invasive fungal rhinosinusitis, and its level of 1-3-β-D glucosan reaches to 21.82 pg/ml. We compared the result of the study group to the control groups, and found that there is significant deviation beteen the two groups.

结果 经过实验检测20例真菌性鼻窦炎(19例为真菌球型，1例为慢性侵袭性真菌性鼻窦炎)及5例对照组患者血浆中1-3-β-D葡聚糖的含量，可以发现其中18例真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量大于试剂盒的诊断标准10pg/ml，其中一例慢性侵袭性真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量达到21.82pg/ml，2例真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量小于10pg/ml，而对照组患者血浆中1-3-β-D葡聚糖的含量均小于10pg/ml，病例组与对照组间采用卡方检验测得卡方值为16.071，(P＜0.05)两组间有差异，有统计学意义。

The results from statistic data analysis using the statistic software SPSS15.0 for descriptive statistics, chi-square evaluation, laddered logistic regression, factors analysis, credibility analysis, variables analysis, and multiple comparison are as follows: I. An analysis of the prominently related variables with whether or not to receive cervical smear screen of tendency factors, enabling factors and needs factors by using the logistic regression model was performed.: 6 variables of tendency factors with predictive value as to whether a woman receive cervical smear screen or not include age, marital status, educational level, family structure, religion, and the knowledge of free smear examination offered by mandatory citizen health insurance; 4 variables with enabling factors with predictive value include average monthly income, district, whether receiving telephone or letter notices in the past year, and the degree of convenience of the examination location. One variable of needs factors with predictive value: is the suitability of the examination time notified. The accuracy rate of laddered logistic regression model built by this research was 74.1%.

利用统计软体SPSS15.0进行描述性统计、卡方检定、阶层式逻辑斯回归、因素分析、信度分析、变异数分析、多重比较等统计方法分析，根据统计资料分析结果：经卡方检定后，将倾向、能用、需要因素中具有显著相关变项与是否接受抹片检查，放入逻辑斯回归预测模型中，本研究结果发现：倾向因素中的六个变项：年龄、婚姻状况、教育程度、家庭结构、宗教信仰、是否知道健保提供免费抹片检查对受检与否具有预测力；能用因素中的四个变项：平均月收入、地区别、过去一年内是否接到电话或信函通知、收到通知的受检地点是否方便对受检与否具有预测力；需要因素中的一个变项：收到通知的受检时间是否合适对受检与否具有预测力；本研究所建立的阶层逻辑斯回归模型的整体预测正确率为74.1﹪。

The data was analyzed by chi-square,stepwise regression analysis and covariance statistics.
