电力自动化补偿技术分析

众所周知,电力自动化补偿技术一直以来都备受电力行业工作人员的高度青睐,主要是由于这种技术在电力企业发展的过程中占据着重要的作用。在电力企业发展的过程中,电力工作人员一直采用自动化补偿技术,但是传统的形式存在着较大的弊端。无法满足社会发展的需求。而且这种电力自动化补偿技术只可以在三相平衡的电力系统中应用,局限性较大。为了对其进行高效改进,工作人员应该对电力自动化补偿技术进行分析,不断提升电力系统运行的高效性。     

短竿细线斗大鲤

前年10月的一个星期六,我与友人一大早便到深圳小梅沙度假村一鱼塘垂钓。这天多云间阴,气温约29℃,约2级左右东南风,正是钓友企盼的好天气。 我是公司钓鱼协会集训队的队员,平时训练以短竿细线钓尾数为主。这一天我便用国产名水牌2.7米手竿齐竿线垂钓,主线为1号线,脑线为0.8号线,钩为金龙4号无倒刺钩,漂为小鱼儿3号漂,用自己调配的混合料为钓饵。这种饵料是用市面上卖的东峻鲤鱼料、罗非料、鲫鱼料按一定比例混合,并加入一些诱鱼辅料调配而成,各种鱼都爱吃。下钩几分钟便开始上鱼,大多是一些

The dimensional accuracy of preparation of femoral cavity in cementless total hip arthroplasty

Objective: To observe the accuracy of femoral preparation and the position of the cementless prosthesis in femoral cavity, and to compare the results between the computer-assisted surgical group (CASPAR) and the conventional group. Methods: Ten femoral components were implanted either manually or by CASPAR in cadaver femurs. The specimens were cut to 3 mm thick slices. Microradiograms of every slice were sent to a computer for analysis with special software (IDL). The gaps and the medullary cavities between component and bone, the direct bone contact area of the implant surface,the gap width and the percentage of gap and bone contact area were measured in every slice. Results: In the proximal implant coated with HA of the CASPAR group, the average percentage of bone contact reached 93.2% (ranging from 87.6% to 99.7%); the average gap percentage was 2.9% (ranging from 0.3% to 7.8%); the maximum gap width was 0.81 mm and the average gap width was only 0.20 mm. While in the conventional group, the average percentage of bone contact reached 60.1% (ranging from 49.2% to 70.4%); the average gap percentage was 32.8% (ranging from 25.1% to 39.9%); the maximum gap width was 2.97 mm and the average gap width was 0.77 mm. The average gap around the implant in the CASPAR group was only 9% of that in the manual group; the maximum and average gap widths were only about 26% of those in the manual group. On the other hand, the CASPAR group showed 33% higher bone contact than the manual group. Conclusion: With the use of robotics-assisted system, significant progress can be achieved for femoral preparation in total hip arthroplasty.
