At last, the research test the logistic regression model with sample dada. The results are as the following:(1)Based on the time series dada, the financial early-warning model contains more crucial information reflecting the dada characters, so it can avoid the obvious logic problem in the other analysis such as single section dada and multi-section dada analysis. The test result indicate that the new model have a more accuracy than others.(2) the research adopt the global principal component analysis to settle the problem of multiple collinearity, so the model would be more normative and precise.(3)the early-warning model uses the backward method to regress, so it gets a terser model of only five variables, but it still has a precise forecasting ability.

通过本文研究说明：（1）建立以时序数据为基础的财务危机预警模型，提高了样本中重要财务趋势特征的信息含量，从而克服了国内外单截面及多重截面分析中普遍存在的明显逻辑问题，检验结果表明，利用时序数据建立的logistic财务危机判别模型较截面数据基础模型的判别准确率要高；（2）采用全局主成份分析方法解决了模型中因子间的多重共线性问题，这一处理使logistic回归方法应用的规范度和严谨度得到明显改善；（3）我们采用向后逐步回归的办法进行回归，使模型大大得到了简化，其中只包含五个自变量，但是它的整体预测准确性却仍然比较高，使模型更具有实用性。

Objective To discuss the essence of nonossifying fibroma so as to increase the veracities of clinical diagnosis and treatment among the young.

作者：李勇，刘兴炎，黄光海，甄平，田乃宜，曾凡本目的探讨非骨化性纤维瘤的本质，提高非骨化性纤维瘤的临床诊治准确率。

Thefractal theory have high accuracy and is not influent by the amplitude of current andother uncertain factor, because its principle is to mine the regularity and extract thesimilarity in transient current

因此不受幅值大小和各种不确定因素的影响，准确率是有保证的。

Results:AFI method was much better than AFV in diagnosis of oligohydramnios by ultrasonography.The combination of both methods could obviously improve the diagnostic accuracy of oligohydramnios.Oligohydramnios could cause pregnant complications,the rate of cesarean section,fetal distress,asphyxia neonatorum and meconium -stained fluid improved significantly.

结果：超声诊断羊水过少AFI法优于AFV法，两种方法结合可明显提高羊水过少的诊断准确率，羊水过少易伴发妊娠并发症，且妊娠晚期羊水过少孕妇剖宫产率及胎儿窘迫、羊水粪染、新生儿窒息的发生率明显增加，差异均有显著性。

objective:to explore the method of ultrasonography in the diagnosis of oligohydramnios in late pregnancy,the association of olignophdramnios with pregnant complications and its effect on perineonate.methods:the clinical data in 84 patient with oligohydramnios from january 2004 to december 2006 in our hospital were collected,and 100 patients with normal amniotic fluid volume selected randomly served as control at the same time.the complications of pregnancy and adverse perinatal outcomes were analysed.results:afi method was much better than afv in diagnosis of oligohydramnios by ultrasonography.the combination of both methods could obviously improve the diagnostic accuracy of oligohydramnios.oligohydramnios could cause pregnant complications,the rate of cesarean section,fetal distress,asphyxia neonatorum and meconium -stained fluid improved significantly.conclusion:oligohydramnios in late pregnancy can cause adverse effect to perineonate,it is a dangerous omen to perineonate and need to be done immediately.ultrasonography is a dependable diagnostic method of oligohydramnios in late pregnancy.

目的：探讨超声诊断晚期妊娠羊水过少的方法，羊水过少与妊娠并发症的关系及对围生儿的影响。方法：收集我院2004年1月~2006年12月住院分娩足月妊娠产妇超声诊断羊水过少者84例，与临床符合率相比较，同时随机抽取同期在我院住院分娩的羊水量正常孕妇100例作为对照组，两组妊娠并发症及围生儿情况进行比较。结果：超声诊断羊水过少afi法优于afv法，两种方法结合可明显提高羊水过少的诊断准确率，羊水过少易伴发妊娠并发症，且妊娠晚期羊水过少孕妇剖宫产率及胎儿窘迫、羊水粪染、新生儿窒息的发生率明显增加，差异均有显著性。结论：妊娠晚期羊水过少会给围生儿造成不良的影响，是危险的征兆，需及时处理，超声检查是产前诊断羊水过少的可靠方法。

Results Use this method to examine 90 cases fast specimen of breast neoplasm during operation,and contrast with pathologic diagnosis.the overall accuracy rate is 98.7%,among them there have 60 cases malignant tumor but have not one pseudo positive,and 29 cases benign tumor have not one pseudo negative,1 cases of undefined was diagnosed mucus adenocarcinoma by pathologic examination.
