- This is when to become familiar with its motions, pointing, focusing, different eyepieces, and magnifying powers, so you can then do everything in the dark. 这是你熟悉望远镜的机会,它的运转、指向、调焦、不同的目镜和放大倍数,之后你就可以在晚上干任何事了。
- This microscope is provided with achromatic objectives ,wide field eyepieces, abbe condenser ,,adjustable built in light source ,and coaxial coarse and fine adjustment with focus stop . 本显微镜采用消色差物镜、广角目镜、阿贝聚光镜,连续可调的人工光源及带有限位置的同轴精微动机构。
- The faceblank is an important functional assembly in the overall design of the facepiece,which puts other functional assemblies,such as eyepieces,breathing system,voice transmitter and nosecup etc. 罩体是将防毒面具中各功能部件(如眼窗、呼吸气系统、通话器和阻水罩等)组成为一个整体的骨架,是面罩总体设计中的一个重要部件,涉及面罩十多项技术性能指标。
