of fear occur, people tend to see the causes of that feelings. In the criminal scene, we can say that the cause of the tension is the weapon such as guns, axes, knives. Those weapons narrow the view of the witnesses so that s/he can't see other details of the situation and this brings about the failure in the memory

1-1. Objective ofExperiment
Op-amp는 전압을 증폭시키는 역할을 한다. Input 전압과 Gain을 곱한 값이 Output 전압이 된다. 따라서, Gain의 값에 따라 전압이 커지거나 작아진다. 실험1부터 4까지의 실험은 Inverting amp와 Non-inverting amp로 나누어 실험을 진행하고, 실험5는 테이프 수를 증가시켜 빛의 세기를 조절하여,
3. Experiment Method
A measurement method of sample of powder form is an x-ray diffractometor(Fig. 9).

3.1. Making of Sample Powder
A Sample is made a powder form. A diameter of powder has good reproducibility as smaller. But generally 10~35μm is a suitable size of sample. We must caution a deterioration by air, gas, humidity and pouri
Purpose ofExperiment
Understanding experimental
analyzing method from XRD
Understanding
application of XRD
Understanding
Principle of XRD
Understanding and analyzing of XRD perfectly
Reason of Error
Impurities
Sample
Rough surface
→ Having to fix x,y,z axis
Non uniform powders
→ Changing surface
Geometrical structure factor
High stress
→Distortion, screw.
This experiment consisted of a total of 3 experiments. In the first experiment, three different resistors are measured using a digital multimeter, and these resistors are connected in series, parallel, and mixed to measure the resistance, and compared with the theoretical value of the resistance read in color code. Their average error was 0.15% to 0.46%, and it was confirmed that all exist within
