Why all data in second file "199801020030.LDASOUT_DOMAIN1",what's the use of other files?I don't understand it.

The first 00Z time output file includes only the values for those key state variables with their initial values read from your HRLDAS_setup file and initialization module setup. That is why you see a lot of -9999 or NaN or 0 values in all diagnostic variables. Typically, the first 00Z time output file will not be used.

just one file like the second image,the most files like the first image.SO,I think the all output variables in one file?and other file just current value？

This is weird. I never saw this issue. The second file with all the variables should be the correct one. For all files, it should be like the second one with a full set of the output files. I am not sure why your first file only includes 7 output files. Did you see any errors when the model generates the first file?
Also, could you please copy and paste your namelist.hrldas content here? I want to see how you set up the model output timestep and files.

great. Your previous output file issue is indeed caused by your namelist setup. You can set up SPLIT_OUTPUT_COUNT = 1
