In this paper, firstly the influence of the delamination upon the natural frequencies of a laminated beam is studied in detail. By partitioning the delaminated beam, its natural frequencies are obtained.

本文首先详细分析了层合梁的脱层现象对其振动频率的影响，通过对脱层梁进行分区处理，得到了脱层梁自振频率变化的规律。

When the pane is transparent a laser beam passes straight through, but when the pane is diffracting, it splits the beam, bending it in several new directions.

玻璃片透明时，激光束能直接通过；而当它为衍射态时，它能分解光线，并向不同的方向弯曲光线。

The third difference is this: A beam of ordinary light diverges; a laser beam does not.

第三个不同点是：普通光束分离；而镭射光束却不然。

Methods According to the document of ISO/TC172/GW1 N80 about the test principle and the experimental demands of times-diffraction-imit factor M^2, beam diameters in different z places along the light direction were measured using LBA-300PC laser beam quality analyzing meter made in Spiricon Corporation of America. Hyperbolas were fitted utilizing the measured data.

根据ISO/TC172/SC9/WG1 N80文件对M^2因子的测量原理及要求，用美国Spiricon公司生产的LBA-300PC激光束分析仪，沿光传播方向在不同z位置，测出光束宽度，由测量数据进行双曲线拟合，确定束腰直径和远场发射角，计算M^2因子。

The first beam of light impinges upon the reflective element and is reflected to travel in the same directional path as the second beam of light.

第一束光投射到反射元件（14）上并反射回以沿与第二束光相同的方向路径传播。

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。

High-precision and extreme-sensitivity beam orienting could be achieved by the application of beam nutating and coherent detecting technologies.

它采用光束章动和相干检测技术，可实现高精度和极高灵敏度的光束定向。
