安全位置

In order to solve the heavy workload and the low efficiency of the train maneuver, one kind of train security alarm system based on GPS and INS technique was presented. The Kalman filter used in the information fusion of GPS and ISN was analyzed, solving the problem of the infinite position error of an INS and the slow modification rate of a GPS. By using the original train database to correct the mileage, the precision of the system was improved.

为了弥补目前火车车辆运行中人工统计调度工作量大、效率低等缺陷，提出了一种基于全球定位系统和惯性导航技术的火车安全告警系统的设计方案；重点讨论了GPS/INS在信息融合时所使用的卡尔曼滤波方法，避免了独立的惯性导航系统无限位置误差和GPS的1 Hz慢速数据修正的问题；利用原有国家铁路网数据库进行数据修正，进一步提高了系统的精度。

objective to evaluate the clinical effect of high myopia treated with lasik by a small optical zones flying spot scanner machine.methods 364 cases (721 eyes) of high myopia were treated with lasik by the schwind esiris laser machine with small optical flying spot scanner.the ablation zone was single zone or multi zone.the ablation depth was range of 78～187μm.all cases were followed up for 3～12 months.the changes of their visual acuities,subjective manifest refraction and complications were observed.results postoperatively,at one day and 3 month the visual acuities were 1.0 or better in 72.0%（519/721） and 81.7%（589/721）.the diopter within ±1.00 was 89.7%（647/721） and 90.7%（654/721）respectively.the complications include:decentral ablation 3 eyes (0.42%),decentral flap 5 eyes (0.69%),epithelial ingrowth 5 eyes(0.69%),glare 15 eyes(2.08%).conclusion the clinical effect of high myopia treated with lasik by a small optical zones flying-spot scanner machine was safety and efficacy,although it needs more corneal tissues.

目的 评价小光斑飞点扫描式准分子激光lasik治疗高度近视的效果。方法采用德国schwind esiris准分子激光机对364例（721眼）高度近视进行了lasik治疗。切削模式采用单区或多区切削，切削总量为78～187μm。随访3～12个月，观察术后视力、屈光度和并发症等情况。结果术后裸眼视力≥1.0者，术后1天、3个月时分别为72.0%（519/721）、81.7%（589/721）；术后屈光度在±1.00d以内者，术后1天、3个月时分别为：89.7%（647/721）、90.7%（654/721）。主要的并发症有：偏中心切削3眼(0.42%)、瓣位置偏离5眼(0.69%)、角膜上皮植入5眼(0.69%)、眩光15眼(2.08%)。结论小光斑飞点扫描式准分子激光lasik治疗高度近视的临床效果安全有效，但是需要切削较多的角膜组织。

Avoid to install two brake at the base position of dangerous motor shaft brake wheel, instead, put the second brake on gearbox high-speed shaft side, separate brake is more scientific and safe.
