Based on the real observation data, forecast equitation or forecast model, the dynamics method such as divergence and vorticity calculation, real data correction, ascending and subsidence calculation was used to simulate the 4D field of divergence, vorticity and vertical velocity at different time, different range and different levels. The field was connected to 3D fields of insect trajectories, yielding the flying speed, direction, ascending area and subsidence. Thus the peak of immigratory insect could be timely monitored. A system of the peak of immigratory insect forecast was set up.

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。
