[0032] Example 1
[0033] A method for observing diatom mud with polarized light microscope includes the following steps:
[0034] 1) Weigh 28g of commercially available diatom mud and place it in a mortar, then add 4ml of alcohol and mix and grind for 4 minutes;
[0035] 2) Take 14g Step 1) Place the evenly ground diatom mud in a beaker, add 140ml of alcohol, and place the beaker on a magnetic stirrer for 8 minutes;
[0036] 3) Use a pipette to suck 4 drops of the mixture prepared in step 2) on a glass slide, then place the cover glass on the glass slide, and observe through a polarizing microscope.
[0037] Among them, in step 3), the observation method with a polarizing microscope is as follows:
[0038] 31) Place a glass slide covered with a cover glass on the stage, select a 40x objective lens, insert a polarizer to adjust the light, observe through the eyepiece, turn the animal table to lift the coarse motion screw;
[0039] 32) After finding the morphology of the diatom mud, exchange
