Anonymous users2024-02-07It's due to a program error. The solutions are as follows: 1) The icons in Windows are messed up, or even the icon files are broken and cannot be displayed normally.
You can go to the "C: Documents and Settings now username local settings application data" directory to delete an icon buffer file named "Hidden Properties". After deleting the icon buffer file, the system will re-establish the icon file buffer, and the icon display problem will be solved (the hidden file needs to be displayed).
2) You can also try this method: right-click on the desktop to select the properties Appearance Advanced, select "Icon" in the drop-down list of the "Project" box, change the size of the icon and press OK, and then change back to the original setting and press OK, so that the system will automatically empty and rebuild the data in the cache (remember the number when changing the size). 3) If the fault persists, restore the system or reinstall the system.
4) Open the task manager, find the explorer process, close, this time find that the desktop is gone, it's okay, and then click -file-run-explorer-in the upper left corner of the task manager.

In a nutshell:
BOD: Biochemical Oxygen Demand (BOD) indicates the amount of organic matter that can be metabolized and broken down by aerobic microorganisms. Because the content of such organic matter cannot be measured directly, and the microbial metabolic decomposition of organic matter requires respiration, which consumes dissolved oxygen in water, the amount of organic matter in water can be measured indirectly by measuring the change in dissolved oxygen in the water (which must be the amount of reduction). >>>More
