摘要：为有效解决传统生态混凝土(ECC)力学性能和生态效果无法兼顾的难题,采用粉煤灰以及偏高岭土代替部分水泥作为胶凝材料,以不同粒径范围的石灰岩碎石作为粗骨料,运用正交试验方法,针对水胶比、骨料粒径、粉煤灰添加量与偏高岭土添加量这四个影响因素进行四因素三水平试验研究。研究各因素在设计孔隙率为25%和减水剂添加量为0.69%时对其抗压强度、孔隙率、透水性和pH值的影响,通过极差分析法对正交试验结果进行分析,从而设计出一种能够满足边坡防护需求且符合生态环境要求的ECC最优配合比。研究表明:当水胶比为0.30,粗骨料粒径为3~6 mm,粉煤灰掺量为15%,偏高岭土掺量为10%时,ECC物理力学性能最佳,孔隙率适宜,透水性能良好且pH值最低。该配合比下的ECC可应用于河道及路堤边坡,不仅能够显著提升景观效果,还能有效保持水土稳定,并对生态环境起到良好的修复作用。

摘要：A new structure and working principle of the chip integrated with micro valveless pump for capillary electrophoresis was proposed in this paper. The micro valveless pump with plane structure has advantages of simple structure, and the process technology is compatible with existing micro chips for capillary electrophoresis. Based upon the mathematical model, simulation study of micro pump was carried out to investigate the influence of structural parameters on flow characteristics, and the performance of the integrated micro pump was also tested with different control parameters. The simulation results agree with the experimental results. Three samples, which are amino acid, fluorescein and buffer solution, have been examined with this chip. The results of the primary experiments showed that the micro valveless pump was promising in the integration and automatization of miniature integrated fluidic systems.

摘要：Volcanic eruption is one of the most serious geological disasters,however,a host of facts have proven that the Changbai Mountains volcano is a modern dormant one and has ever erupted disastrously. With the rapid development of remote sensing technology,space monitoring of volcanic activities has already become possible,particularly in the application of thermal infrared remote sensing. The paper,through the detailed analysis of geothermal anomaly factors such as heat radiation,heat conduction and convection,depicts the monitoring principles by which volcano activities would be monitored efficiently and effectively. Reasons for abrupt geothermal anomaly are mainly analyzed,and transmission mechanism of geothermal anomaly in the volcanic regions is explained. Also,a variety of noises disturbing the transmission of normal geothermal anomaly are presented. Finally,some clues are given based on discussing thermal infrared remote sensing monitoring mechanism toward the volcanic areas.

摘要：针对低渗透老油田老井侧向深部剩余油气资源动用难度大的问题,形成了柔性侧钻水平井挖潜技术,并开展了现场试验。该技术首先采用柔性侧钻钻具在老井筒中实现低成本侧钻,然后采用水力喷射工艺诱导多条裂缝起裂,最后下入油管柱对侧钻井眼实施笼统多簇暂堵压裂,从而实现井间剩余储量的高效挖潜。该技术包含柔性侧钻水平井钻井和侧钻水平井压裂2项技术,前者主要涉及柔性钻杆结构和材料优化、钻进工艺、密闭取心工具3个方面,后者主要涉及压裂方案优化、压裂工具及实施工艺优化2个方面。该技术在长庆安塞油田开展了多轮现场试验,发现通过改变井型、缩小油水井排距,可以较好地建立压力驱替系统,实现压力的有效传导,从而达到低产低效井提液增产的目的,同时验证了该技术可为低渗透油藏剩余储量精准挖潜、储层精细动用提供有力支撑。
