It is proved that if R is a σ rigid ring and()_ZR is torsion free,then R is a Baer ring if and only if the ring of skew Hurwitz series over R is a Baer ring,and R is a Clean ring if and only if the ring of skew Hurwitz series over R is a Clean ring.
我们证明了:(1)如果R是σ刚性环并且ZR无挠,则R是Baer环当且仅当R上的斜Hurwitz级数环T是Baer环;(2)R是Clean环当且仅当R上的斜Hurwitz级数环T是Clean环。

基于CLEAN算法的非连续谱线性调频中断波信号处理
2.
The CLEAN algorithm is introduced from non-instant u-v coverage aperture synthesis in radio astronomy to instant situation in 2-D airborne mm-wave imaging, to remove the bad influences of the undersampled u-v plane coverage to image quality so as to eliminate the negative impacts on the image caused by high side slobs.
该文将非即时u-v覆盖的综合孔径射电天文观测中的CLEAN算法应用到即时u-v覆盖的机载二维被动毫米波综合孔径成像中,避免因空间频率覆盖的不完整而产生对图像质量的影响,以达到消除高旁瓣对图像产生的负面影响。
3.
CLEAN algorithm has the limitation of iterative dithering and convergence instability when it was applied to extend sources processing.
为了解决CLEAN算法处理展源时存在的迭代抖动、收敛不稳定的弊端,借鉴最大熵算法的平滑约束概念,通过修正CLEAN算法迭代过程中的脏束,提出了带有平滑约束的CLEAN算法。
6)  CLEAN technique
CLEAN技术
补充资料:clean brine
分子式:
CAS号:

性质:经过滤处理,不含粒径在2μm以上的悬浮粒子的盐水溶液。主要用于须与产层接触并可能进入产层的完井或修井作业中,如射孔液,砾石填充液、洗井液或其他特殊目的的工作液。清洁盐水因配制及维护要求较高,一般只用于低渗透性或对损害敏感的产层的完井及修井作业。清洁盐水中带回无损害性的添加剂调整性能。
