(1) by moving slightly moving stage, with a total of cross eyepiece reticule, length measurement.

(2) by rotating load and eyepiece at the lower end of the vernier angle differential wheel, with full eyepiece site character base marking, angular measurement, make to be at one end of the angle alignment cross lines coincide, then let the other end coincidence.

(3) using the standard detection of thread pitch, pitch diameter, diameter, tooth angle and tooth size or shape etc..

(4) the grain condition of the metallographic surface.

(5) inspection of the surface of the workpiece processing.

(6) to detect whether the size or profile of the micro workpiece is in conformity with the standard piece.

Around us, small to our eyes see not see bacteria, the towering sky tree, birds from the air, fish to water, these living objects are biological.

Biology is a natural science of studying biology.

A major problem facing the world today, such as food shortages, population growth, environmental pollution, and biology have direct relationship. Now biology has been the rapid development, cultivated by means of gene technology of food has been put on the table of ordinary people, the gene method has begun to save the patient's life; cloning technology make replicas of animals become possible.

People believe that biotechnology will have an important impact on twenty-first Century, it will promote the progress of human society, a hitherto unknown contribution to human beings survive better.

Biology is an experimental science, this set of material equipment, will lead you to explore the wonders of the biological world, preliminary study of biological skills, to lay a solid foundation for future study.

In a small microscope, there is another bright and colorful world waiting for you to find the :

Try to cut open the plant and observe the plant cells. Enjoy the aquatic plants in the water swimming. Help you become an amateur microscope detective. For your homework, slide making and school showed detailed and convenient help.

Is just a leaf green, under the microscope are showing a little-known life. Microscope to take us into a previously unexplored world, tell us what things are not as we have seen, is often in the ordinary surface is a unusual. The wonderful, vibrant world of the microscope is fascinating to me, for it is also a rich and colorful world in the tiny world.

let's discover the wonderful side!

Practical operation experience

, a step: people observe hair

1, cut the hair, about 5mm length.

2, the hair on the slide, dropper a drop of water on a glass slide, and then tissues to absorb water, so that the hair stuck on a glass slide.

3, the slides are put under the microscope.

Two, DIY culture and observation of Paramecium steps:

1, the farms used to bind dish rope cut into about one inch long segment, placed in a wide mouth container, add light salt water soak for more than a week.
2, take a drop of water, under the microscope can be observed very active in paramecium.

Three, observation of human oral cell steps:

1, on a slide with a drop of dilute brine, with sterile toothpick in oral cavity wall gently scraping a few.

2, the end of the toothpick with debris smear a few on a slide.

3, tweezers from clean coverslip, it is the first contact slide drops of water, and then gently covered with water drops.

4, on one side of the glass, add a drop of diluted gentian violet (iodine), by suction from the other end of the attraction, dyeing liquid infiltration to the specimens of all on the microscope observation.

Four, observe wings, antennae, foot steps of insects:

1, catch a small insects, such as mosquitoes, ants, butterflies.

In 2, a drop of water on a glass slide, tweezers to remove a small piece of insect wings (tentacles and foot); put in a drop of water

3, the water absorption of paper were removed, stuck to the slide.

4, under the microscope observation.
