space increment meaning in English

空间增量

The experiments show that the phase scanning method is right and innovative and the ability of the sub - nanometer space increment is reached . since it only require an extra phase scanning device , the whole system has higher reliability and practicability
由于该方法只需在现有的光电式光栅刻划机上附加相位扫描装置，因而系统的整体可靠性更高、更实用。
Since the space increment within nanometer or sub - nanometer is required , it is difficult to make it only by improving the precision of the graduation system . a phase scanning method for fabricating the vls grating is suggested initially in this dissertation
实验结果表明，本文捉出的相位扫描方法原理正确，具有创新性，达到了变栅距光栅所要求的亚纳米级的栅距变化精度。
It is . a big problem to fabricate the vls grating , considering its space increment varies within sub - nanometer . hence , the grating ruling engines , in u . s . a , japan or russia , for vls gratings have very complicated graduation control system . although they have fabricated practical vls grating , their costly devices do n ' t adapt to the fabricating practice in our country
针对于此，美国、日本和俄罗斯等极少数国家为光栅刻划机设计了十分复杂的分度控制系统，虽然刻划出了具有实用性的变栅距光栅，但其复杂、昂贵的设备不适合我国光栅加工的具体情况。
