This instrument can clue on baseline shift to decide the frequency of background scanning, which can deduce NIR analysis error and improve NIR veracity.
该仪器具有基线漂移提示功能，从而确定仪器背景采集的频率，可以降低分析误差，提高检测结果的准确度。
Background &Objectives:It was difficult to get a good tissued ose distribution using fixed field irradiation technique in large field. But the translating scanning beam irradiation can make it.
背景与目的：用固定野技术行特大野照射时，很难得到理想的组织剂量分布，而平移扫描式照射却能做到。
Then approximate wave impedance is computed after background velocity has been obtained by making constant-velocity scanning.
并在常速扫描取得背景速度的基础上计算近似波阻抗。
After nine years of scanning the sky, the Wilkinson microwave Anisotropy Probe (WMAP) space mission has concluded its observations of the cosmic microwave background, the oldest light in the universe.
经过9年对天际的扫描，威尔金森各向异性微波探头(WMAP)航天任务得出了对宇宙微波背景辐射(及宇宙早期“光线”)的观测结论。
Dr Breckon thinks intelligent scanning systems will at first operate in the background at airports, for instance rechecking bags in case human inspectors have missed something.
Breckon博士认为智能扫描系统将会最先用在机场，例如复查行李包裹，以防检查员漏检。
After scanning the object image and labeling the connected component, the background and foreground noise could be removed easily by threshold value area expunction.
