目标透镜 meaning in English
objective lens
Examples
- The second arises from the spherical aberration present in the objective lens
第二个出现在目标透镜的球面像差表面。 - The specimen is mounted in a special holder which fits into the bore of the objective lens and enables the specimen to be tilted through angles greater than 30 about two orthogonal axes so that appropriate crystallographic analyses can be carried out
样本被架在特殊的支架上，支架被放置在目标透镜的圆孔中，使得标本倾斜的角度能够超过30穿过两个正交的角，然后适用的晶体学分析再展开。 - Electrons which pass through the thin specimen are brought to a focus in the back focal plane of the objective lens , this lens , like all electromagnetic lenses , acts as a converging lens and thus forms a diffraction pattern in this b . f . plane
穿越薄样本的电子被带到目标透镜背面焦点平面的一个焦点，这个透镜，象所有的电子透镜一样，充当了聚焦透镜的作用，因此，构造了在这个背面焦点平面的衍射模式。 - This is achieved experimentally by focusing the selector aperture on the final screen using the diffraction lens , which is most accurately done after removing the objective aperture , and then ( after replacing the objective aperture ) focusing the specimen using the objective lens only
这已经通过使用衍射透镜在最终屏幕上聚焦选择孔实验性的完成，此方法多数能在移动目标孔后准确完成，然后（重置目标孔后）仅通过目标透镜聚焦样本。
