The paper presented a method of detecting long-range correlation in a signal--detrended fluctuation analysis and applied it to diagnose gear faults. Two key problems, i.e. scaling range and polynomial order of fitted trend, were discussed. Scaling exponent was extracted to be as a detector for diagnosing five types of gear faults, their were normal, spalling, tooth broken, wearing and cracking.

探讨了一种检测非平稳信号中长程相关信息的方法--利用去趋势波动分析（detrended fluctuation analysis，DFA）方法来诊断机械故障，着重研究DFA的尺度范围选择、趋势拟合阶数选择等关键问题，提取尺度指数作为诊断的特征参数，应用于齿轮的正常、剥落、断齿、磨损、裂纹等五种状态诊断，正确率达96％以上。

Friction tests in moving water and field sheer tests and seepage model tests and the effects of seepage defending and rough ratio tests and the capacity of resisting from frozen bulge and ice pressure. 2. Through the series track ageing tests of geosynthetics for 14 years, if the covering is 40cm thick and the initial strength is more than 500N/5cm, the geosynthetics can be used for at least 50 years, most to be more than 100 years. Under the same conditions, the strength and elongation of geotextile are both decrease, and for geomembrance the strength increased in early days. One important ageing index for geomembrance is embrittlement.

2通过工程现场14年的取样，进行老化试验分析，结果显示，土工合成材料在40cm厚以上岩土严密保护的条件下，初始强度大于500N/5cm，使用年限至少可达50年，多数情况可超过100年；在同等条件下，土工织物老化在力学性能上的表现是强度和延伸率都呈下降趋势，而多数土工膜在初期力学性能上表现是强度增加延伸率下降，到后期强度和延伸率才都呈下降趋势，脆化是衡量土工膜老化性能的重要指标。

Macro-control on the healthy development of real estate trend is relatively good, investment growth trend, there have also been a decline , to reduce market supply, there will be a very interesting price scissors: the rate of decline in investment, supply reduction, demand continued to maintain levels.

Under the condition of not considering the local topology effect and using a simplified layer velocity structure , we obtain the following results:(1) For a vertical strike-slip fault, the stations located on the parallel side of the slip , the transvers component ground motions show faster attenuation than the radial component motions.

对垂直走向滑移断层而言，沿著与断层面走向平行分布的测站，其与断层面走向平行分量的峰值，和其他二分量相较之下，有较明显的衰减趋势；而沿著与断层面走向垂直分布的测站，其与断层面走向垂直分量的峰值，和其他二分量相较之下，有较明显的衰减趋势。

Seed was stored in a storage temperature, the galactose content of seed decreases as the seed moisture content decrease. However, the glucose, fructose, sucrose and raffinose content of seed increase as the seed moisture content decreases, but this kind of change is not clear if seed was stored at lower temperatures ranges from 20℃ to -18℃.

然而葡萄糖、果糖、蔗糖和密三糖的结果与半乳糖的变化趋势相反，随着贮存温度的升高，四种糖的含量逐渐下降，在同一贮藏温度条件下，随含水量的降低，这四种糖的含量却逐渐升高，但在贮存温度较低时(20℃和-18℃)，这种变化趋势不明显。
