the figure of XRD and did research and discuss background knowledge. Also we expect that we can find important information of XRD by doing experiment
Process of experiment
XRD is equipment that use characteristic X-rays. Through characteristic X-rays diffraction peak of material, we can examine closely unknown Specimen. Theory that is used in this equipment is Bragg's law(2d sinθ = nλ
the capabilities of a TEM). It was found that by increasing the accelerating voltage from 5kV to 15kV improved the EDS acquisition by taking advantage ofthe high peak-to-background ratio inherent in thin specimens, such as carbon extraction replicas, due to the small interaction volume.

A protected face transducer is a single element longitudinal wave contact transducer that can be used with either a delay line, protective membrane, or protective wear cap.
3) couplant A couplantis a material (usually liquid) that facilitates the transmission of ultrasonic energy from the transducer into the test specimen. Couplant is generally necessary b

The first one is called the 'static method' that is the way to measure the deformation strain that are corresponded to applied force using the strain gage. In other way, 'kinetic method' can measure the Young's modulus using 'sonic resonance test' and 'pulse echo overlap.' In sonic resonance test, sonic wave or impulse are applied to thespecimen for finding the resonance frequency ofthe sample
