| 1. | Objective working distance : 25mm
物镜工作距： 25mm |
| 2. | The working distance is the distance from the front of the lens to the object under inspection
工作距离是由镜头前到观察目标物的距离。 |
| 3. | The coupling efficiency can obtain 75 - 85 % at the wide working distance of 100 - 200um
这种方法的耦合效率在一定条件下可以在100 ? 200 m的工作距离上达到75 - 85 。 |
| 4. | When working with a hotstage in transmitted light it is necessary to increase the working distance of your standard condenser
透射光下使用热台时，有必要增加你的标准聚光镜的工作距离。 |
| 5. | A lens is primarily defined by its focal length . figure 4 illustrates the relationship between the focal length of the lens , field of view , sensor size , and working distance
一个镜头的基础定义是其焦距，图4图示出镜头焦距，视野，感应器大小，和工作距离间之关系。 |
| 6. | Upon the request from some institutions that have the practical needs for uwa applications , the research is conducted to achieve the objective of developing a digital underwater acoustic voice communication system with longer working distance
本研究是根据很重要的应用单位对更远作用距离语音通信机的需要而选题的。 |
| 7. | Determine the height of any object , including any tools , equipment , apparatus or vehicles , and maintain a safe working distance between the object and the overhead line as advised by the relevant electricity supplier
确定所使用任何物件(包括任何工具、设备、器具或车辆)的高度，以及按有关供电商提供的意见，保持物件与架空电缆之间有安全的工作距离。 |
| 8. | The nature of the multipath effect ( mpe ) has decided that phenomenon that the longer the working distance is adopted , the worse the multipath effect ( mpe ) plays the role . the new methods should be studied and employed to eliminate or mitigate the negative resulted by multipath effect ( mpe )
由多途径效应产生的机理可知，通信距离的拓展将使多途径效应的影响更加严重，所以必须研究水声通信中抗强多途径干扰的各种可能措施。 |
| 9. | In the retrofocus project , a retrofocus structure with two elements is used in the object lens to enlarge fov and back working distance , in the head of which the negative meniscus have the effect of balancing aberration and deviating rays like a prism . and a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive
反远距设计方案中物镜采用二片式反远距结构,增大了视场和后工作距离,弯月型负透镜在前,具有平衡像差和棱镜的偏向作用;物镜后放置高折射率标准超半球型浸没透镜,满足小光敏面探测器接收。 |
| 10. | Ysx series operation microscopes , using fibre - optic cable for coaxial illumination , have different working distance and illumination , have different working distance and magnification . they are featured for flexible handling and easy operation . they have found wide applications in ophthalmology , gynecology , ear - nose - throat , surgery and orthopedics etc
