Secondly, the distribution feature with nonuniformity of the palaeotectonic stress field is clarified and the stress values are estimated.
其次，利量大量事实阐明，构造应力场的空间分布具有不均匀性的特点，并对两期应力场的应力大小作了估算；
2
The two-point correction method is analyzed, and a new real-time nonuniformity correction algorithm for IRFPA is proposed by using field programmable gate array(FPGA).
