For choosing a material to interfere with IR and laser,the IR and 10.6μm laser transmissivity of micron-copper powders of different components were tested in the smoke chamber,when the concentration of the smoke reached 1.0 g·m-3,the transmissivity of 1~3μm,3~5μm and 8~14μm IR under 30%,and the transmissivity of 10.6μm laser under 20%,the attenuation ability of red copper powders,green and red copper powders and green copper powders to IR and 10.6μm laser increased gradually.At the same time,the interferent...

为选择一种能够遮蔽红外与激光的烟幕干扰材料，在烟幕箱中测试了组分配比不同的微米铜粉的红外与10.6μm激光烟幕透过率，当烟幕浓度为1.0 g.m-3时，1~3μm，3~5μm，8~14μm红外的透过率均小于30%，10.6μm激光的透过率小于20%，红光铜粉、青红光铜粉和青光铜粉对红外与10.6μm激光的衰减能力逐渐增强；同时测试了微米铜粉对红外热像仪的干扰效果，浓度为2.0 g.m-3时，青光铜粉能够完全遮蔽红外热像仪。

The Nd: YAG laser iridotomy hemorrhage can be minimized by thor- ough coagulating burns of the target tissue from an argon laser. The initial several argon laser burns may cause iris vessels congested and result in more severe bleeding during the succedent Nd: YAG laser shots.

三、先用氩激光热凝虹膜，能否减少后继Nd：YAG激光击射所致的虹膜出血，取决于组织的热凝固程度，如热凝不充分，基质血管扩张充血，反有加重出血程度的可能。

In the rabbits, every Nd: YAG laser iridotomy smaller than 200μm and argon laser iridotomy, Nd: YAG laser combined with argon laser iridoto- my smaller than 450μm closed by the first postoperative week. The mecha- nism for iridotomy closure was assumed to be iris pigment epithelial prolifera- tion, migration and the reformation of stromal connective tissue once the pos- terior pigmented cells have initially bridged the iridotomy.

The old system of laser range finder, which processes laser emission system, laser incepting system and measuring round-trip time of light pulse by separated cell circuit, makes the cost of exploiture expensive, debugging difficult, circuit complex, precision inaccurate, reliability low, bulk and weight great, even without any standard suited gate together with other instruments. Therefore, popularization application of laser range finder is cumbered.

早期的激光测距系统在激光接收机中通过分立的单元电路处理激光发、收信号以测量光脉冲往返时间，使得开发成本高、电路复杂，调试困难，精度以及可靠性相对较差，体积和重量也较大，且没有与其他仪器相匹配的标准接口，上述缺陷阻碍了激光测距系统的普及应用。

Mobile positioning system or dynamic table so that the laser head is cutting material in the system-driven subcapital high speed, laser head from the light source and cutting heads, light source produces a very short wavelength focused laser beam, laser beam through cutting heads, vertically focused the material being cut on the surface, heating and melting, evaporation is cutting material, resulting in the closure of Lancing, slotted openings formation pads.

移动定位系统妪动工作台或激光头，使得被切割材料在系统驱动头下高速运动，激光头由光源部分和切割头组成，光源部分产生波长很短的聚焦激光束，激光束通过切割头，垂直聚焦在被切割的材料表面上，加热、融化、蒸发被切割材料，形成切缝，闭合的切缝形成焊盘开孔。
