How many years of ups and downs has affected the survival of the ancient trees has formed the annual rings, which have made the wood grain structure unique. This is also a recorder who reflects the climate from ancient times to the present. Therefore, it is an important basis for estimating the ancient meteorology for the gap between the annual rings of old trees and the degree of density in the section and its variation. So how to choose instruments to detect ancient trees is very debatable. Ancient trees and trees non-destructive testing flaw detector apparently entered the eyes of people.

In recent decades, scientists have explored the use of images as an NDT in certain situations, which is more intuitive and convenient than using digital quantities and analog quantities, and can more accurately reflect objective things. The most common methods for the human NDT method are X-ray and ultrasound techniques. It can not only detect various cross-sectional images of the human body, such as storing multiple cross-sections to form a stereoscopic image at the same time. It can even provide a process of how the human brain or other human organ carries out metabolism. This lively process is vividly displayed in images one by one. However, this method is to take or inject various elements of a short radiation cycle in the human body to emit gamma rays to facilitate detection. Neutron ray imaging has a killing effect on human organisms and is generally used in industrial products.
Through the determination of ancient and famous non-destructive testing flaw detectors, several NDT imaging techniques are compared roughly, and microwave imaging technology has many advantages through preliminary analysis. Moreover, from the technical point of view, the quality and speed of imaging can also be improved, the price can be reduced, the resolution of the image, and the measurement speed can be improved through technical means. 
The rig's speed, torque, thrust axial pressure, reverse axial pressure, thrust speed, and lifting speed can be adjusted at any time to meet the requirements of different drilling tool working conditions and different construction processes
2.Top-drive slewing propulsion lift
