种差异

There was a significant difference in the SI mean value between SIa and SIb.

两种症状相关指数均值比较差异有显著性。

Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.

约有5%发生肠穿孔的民众在筛检后14天内死亡，做完直肠镜或大肠镜后发生肠穿孔的民众死亡率明显增加（大肠镜：危险比，9.0；95%信赖区间，3.0 - 27.3；直肠镜：危险比，8.8；95%信赖区间，1.6 - 48.5），但这两种筛检方法的风险差异正在逐渐缩小中，可能是因为技术的改良与人员的加强训练，使得大肠镜的肠穿孔危险已逐年下降。

Pulmonary function (FEV1%pred), peak VO2, maximal workload, dyspnea, and quality of life were measured at pre- and post-exercise training. Percentage, mean, standard deviation, Mann-Whitney test and Wilcoxon Signed Rank test were used for data analysis.

资料分析以SPSS10.0套装软体，进行百分比、平均值、标准差、 Mann-Whitney test及Wilcoxon Signed Rank test，以探讨两种运动训练之影响成效，及比较两组成效之差异。

According to the identification of fossil woods, it shows that they all belong to Araucarioxylon, with the stage age of Qixia, though there are some anatomical differences among them; Following two mathematical clustering analysis methods-analysis of variance and CSDM curve, metrical numerical values are quantitatively analysed, then, skew value of curve and its relationship with leaf longevity are showed.

经过鉴定研究认为，本区的木化石均属于松柏类中的南洋杉型木属，为栖霞阶化石；应用方差分析、CSDM曲线相关分析等数学聚类分析方法，对木化石标本的测量数据进行了定量分析研究，探讨了曲线偏差值与叶寿命的关系，认为本区二叠纪木化石均为常绿树种-南洋杉型木，但有可能存在落叶树种，且生长年限有较大差异。

Dynamic reliability under Littlewood-Paley wavelet is the biggest, dynamic reliability under modified meyerwavelet and harmonic wavelet are close. Analyzing the dynamic reliability of structure under odd exponent wavelet is very simple, it doesn't calculate Power Spectral Density function integral, it is only to calculate the square of displacement standard deviation and the square of velocity, then the dynamic reliability of structure can be concluded by max distribution. In addition the effects of upper limit is considered, when upper limit is smaller, the dynamic reliability of structure is less, that is, the damage possibility is bigger.

通过结构地震反应在小波基下的动力可靠性分析说明：无论是单自由度还是多自由度从理论上推导在这四种小波下的结构动力可靠性是可行的，而且考虑的结构地震反应都是非平稳的高斯过程，方法实现也比较容易；在Littlewood—Paley小波基下求得的结构的动力可靠度比较大，由改造的meyer小波和谐波小波求得的动力可靠度略有差异；单边指数小波下的结构动力可靠性分析非常简单，不用求功率谱函数来积分，只需求得结构地震反应的位移方差，速度方差，利用最大值分布公式就可得到结构的动力可靠时程；另外也考虑了超越界限对结构动力可靠度的影响，超越界限越小，结构的动力可靠度越小，即破坏概率越大。
