4. Thematic Mapper, TM images are images obtained by Thematic Mapper. Starting from Landsat-4, thematic mappers (TM) have been installed on launched satellites to obtain information on the Earth's surface.
TM has greater improvements than MSS images in terms of spectral resolution, radiometric resolution and ground resolution. In terms of spectral resolution, it uses 7 bands to record target feature information obtained by remote sensors.
5. Memory T cells, memory T cells (TM), are human immune cells. The third line of defense of human immunity is divided into two parts, one is humoral immunity and the other is cellular immunity.
After T cells divide and differentiate, they will form memory T cells and effector T cells respectively. The memory T cells will mobilize the anti-virus methods in their memory again when the next antigen invades and kill again. antigen.
