精确聚焦 meaning in English
sharp focusing
Examples
- The aim of defocus detection is to achieve high etching quality by providing the defocus error signal for focus - servo system which can make the etching spot focus accurately
离焦检测的任务是为聚焦伺服系统提供聚焦误差信号,使写入光斑能够精确聚焦,从而保证刻蚀质量。 - Whole - body gamma knife whole - body gamma knife is a pioneer large radiotherapy equipment in the world , which is mainly used for treating pathological changes such as tumors and nidi in the all parts of the body
体部伽玛刀是一种填补世界空白的大型放疗设备，它特有的高剂量高精度高疗效低损伤的治疗效果，能完美实现精确聚焦适形放疗的目的。 - However , the normal tissues around are only affected by a slight radiation so that the damage degree is extremely low . the whole - body gamma system can offer unmatchable advantages including heavy dosage , high precision , dramatic curative effect and low damage
体部伽玛刀能达到普通放疗所不能达到的高剂量高精度高疗效低损伤的治疗效果，能完美实现精确聚焦适形放疗的目的。 - Thirdly , a modified extended chirp scaling ( ecs ) algorithm is presented , which solves the problem of producding fine focused images in the class of chirp scaling ( cs ) algorithm . lt can be used for uwb - sar imaging effectively . the phas e error produced by cs operation are analyzed . a windowed process in two dimension frequency domain before cs operation are proposed . it can improve the quality of image and widen the effectively swath and increase the peak to sidelobe ratio ( pslr )
然后针对chirpscaling ( cs )类算法不能对参考点精确聚焦的问题，提出了一种改进的扩展cs ( ecs )算法，实现了对uwb - sar的高效成像；分析了cs操作产生的相位误差，提出在cs操作之前在二维频率域对信号加窗，除有效提高信号的峰值旁瓣比( pslr )外，还可以提高图像质量，增加有效测绘带宽度。 - " body gamma knife is mainly used for curing all kinds of body tumors , and the latest generation three - dimensional directional actinotherapy devices . it incorporates many modern high - techs and effectively break through the limit of actinotherapy devices available while precisely focused and three - dimensional directional . it also has adjusted actinotherapy , wide range irradiation and common actinotherapy , and protects the normal organism from damage at best while its dosage precisely destroys tumor organism
“体部伽玛刀”主要用于治疗各种体部肿瘤，是目前世界上最新一代立体定向放疗设备，它吸收了众多现代高新技术成果，有效地突破了现有放射治疗设备的局限，兼备精确聚焦立体定位等优点，具有适形调强放疗大野照射及普通放疗等多种功能，能够在剂量准确摧毁肿瘤组织的同时，最大程度地保护正常组织免受损伤。
