In an environment where people's living standards are gradually improving, people are increasingly paying attention to the improvement of quality of life and the pursuit of comfort.
On a sunny afternoon, hold a cup of tea, lean against a bamboo bench, lean on a wooden ladder, close your eyes, and enjoy this long, slow life...
There are certain reasons for arranging this adjustment in the first and last paragraphs, because everyone is always the most cautious when they step on the stairs, and when they walk up, they are familiar with the rhythm of the steps and the alert in their hearts. Will gradually relax. At this moment of relaxation, we are walking in the middle of the stairs, so the step height in the middle of the stairs should be as constant as possible. According to scientific calculations, the reasonable range of step height change is generally within 4 cm, usually 2 cm to 3 cm, and the range of variation of the first and last steps is also controlled.
Stairs occupy an increasingly important position in the home decoration, choose a staircase suitable for yourself and your family, and make life more beautiful!

Optical Microscopy
In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.
