Experimental results prove that this focusing structure is characterized by his compact volume, high rigidity and well precision.
试验结果表明，该空间调焦机构具有结构紧凑、刚度高、位移精度好等特点，能够满足空间调焦的设计要求。One man was aiming a camera on a tripod through a glass door, zooming in on a ship across the harbour: China's first aircraft carrier.
一名男子正在给一部固定在三脚架上的相机调焦，镜头透过一扇玻璃门，对准了港口另一侧的一艘船只：中国首艘航空母舰。That means that the eye is somewhat shorter than ideal, causing the eye to exert focusing effort at ALL distances in order to see clearly.
意思是视力比理想的近一些，为了看得更清楚，眼睛尽力调焦到所有的远处物体。Then the eye is relaxed for distance and the entire amount of focusing ability is available to see close.
远视的眼睛得以松弛，用全部调焦能力近看。Focusing is one of the key technologies of high-resolution remote sensing camera to receive high quality images.
检调焦是高分辨力遥感相机得到高质量图像的关键技术之一。To compensate the defocusing of a dual-band aerial camera in a complicated environment, a focusing mechanism is designed.
为了补偿双波段航空相机在复杂环境下产生的离焦，设计了一套调焦机构。The focusing muscle (ciliary muscle), which controls the shape of the lens, is thus in a constant state of contraction.
这种控制晶体形状的调焦肌肉（睫状肌），长期处于收缩状态。Experimental results show that the system can realize good focus in a wider range of illuminance .
实验结果表明，在较宽范围的光照度条件下，应用该系统均能获得良好的调焦效果。Experimental results show that the system can realize good focus to immobile targets and most mobile targets in the working environment.
实验结果表明，在外场工作条件下，应用该系统对静止目标和多数运动目标均能获得良好的调焦效果。
