This study is a kind nonequivalent pretest-posttest designs of quasi-experiment in life education. The experimental group is the six grade class led by the researcher, and the control group is another six grade class of the same school. The researcher executes analysis of covariance of the grade school pupils' life attitude evaluation scale and quality data, in order to explore the meaning, value and feasibility of life education. The researcher wishes to become the reference for someone who wanted to work about the life education by executing the curriculum of life education.

A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.
中文摘要:以气液固三相喷射环流反应器为研究对象,将高速CCD和光纤束耦合制成局部瞬态流动特性微机数据采集及图象处理系统,利用MPS硅烷分子在带有羟基的玻璃基底上的自组装引导SnO2晶态膜层在功能化表面上进行沉积,以获得表面标记的示踪粒子,解决图象处理技术与相的识别的问题,利用频闪技术拓展了测量上限,得到可以准确测定气液固三相喷射环流反应器中局部瞬态流动特性的测试系统;采用上述测试技术进行喷射环流反应器中局部气相、液相与固相瞬态流动特性的实验研究,并考察物性参数、操作参数与结构参数的影响规律。

Overwet phenomenon, which is found in the DCFBS experimental research was discussed. The effect of overwet on the desulfurization efficiency and on steady operation of the units was analyzed. It is pointed that the overwet zone in the tower is not only the main desulfurization reaction zone, but also the main scaling zone. It plays an important role for the units operating stably with high-efficiency.
本文对DCFBS实验研究中发现的反应塔内的过湿现象,进行了分析与讨论,并研究了过湿现象对脱硫装置的脱硫效率和稳定运行的影响,指出脱硫塔内过湿区既是脱硫反应的主反应区,也是主要的结垢区,它对脱硫装置稳定高效运行起着重要作用。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3~4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.
本研究结果显示,(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8%~96.7%,并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异;(2)TTE作为影像学引导,除过度肥胖患者外,可完全替代X线引导进行冠状窦电极导管置放,包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导,且较X线C型臂有一定优越性;(3)TTE结合普通X线胃肠透视机作为影像学导引,可顺利完成心内电生理检查时导管的安全到位,而不需昂贵的X线C型臂,可将心内电生理检查扩大到广大的基层医院;(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等,对并发症的防治甚至挽救病人的生命至为重要;(5)动物实验研究表明,TEE可引导射频导管消融术时大头电极导管成功到位。
