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
Oriental in 1986, partly to identify the company more closely with its other famous hotel in Bangkok, the Oriental.
In the mid-1980s, the company decided to expend its hotels beyond the Asia region, largely through equity purchase.
Mandarin Oriental's corporate statement simply says it aims "to be the best." it does not have many hotels, and its preference would be to have five good hotels in

Nowadays, decades after the reform program was first implemented, Mainland consumers, with increasing product knowledge and surging purchasing power, are more sophisticated and value-oriented. Instead of looking solely for low prices, they place strong emphasis on product quality, functions and branding. Branded products, having an up- market image in terms of style, product quality a

오토바이 1에서 발생하는 소음을 L_1, 오토바이 2에서 발생하는 소음을 L_2라 하고, 오토바이 1과 오토바이 2에서 동시에 발생하는 소음을 L_(1+2)라 하면 다음과 같은 관계가 성립한다.
L_(1+2)=10log(〖10〗^(L_1/10)+〖10〗^(L_2/10) )

1980년대부터 집합조직을 방위분포함수(ODF, orientation distribution function)으로 정 량적으로 표현하기 시작했고, 현재 집합조직을 연구하는 대부분의 연구는 집합조직을 X-선 회절법이나 EBSD(electron backscattered diffraction)로 측정하여 방위분포함수로 계산하 고 있다.
