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。

Mechanical properties and combusition characteristics were affected evidently by the solid grain configuration and its character. Mechanical propertiesof the material system could be improved by adopting RDX and proper granularpropellants granularity rank-match. It is favorable to obtain progressivity burning effect byaffiliating increasing burning surface propellant grains. Affiliating fast burning componentthese burning rate regulator in the bond system can quicken burning rate of propellants andimprove burning progressivity.

Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.

For this objection, we propose a kind of optimal interpolator in the senes of the minimizing mean square error, which using the image nonseparable autocorrelation function model and characteristic of circular quincunx interpolator's coefficient distribution. The experiments testified that the interpolating characteristic of APIDCSF is similar to the optimal interpolator. A quasi-vanishing moment curve is proposed here.
