초록
X선회절법(線回折法)을 이용(利用)해 소나무(Pinus densiflora)의 1차조직(次組織)과 2차조직(次組織)의 미세구조(微細構造)의 차(差)를 검토(檢討)했다. 그 결과(結果)는 다음과 같다. 1. 1차조직(次組織)과 2차조직(次組織)에서 (200)면(面)과 (004)면(面)의 면간격(面間隔)은 차이(差異)가 없었다. 2. 1차조직(次組織)과 2차조직(次組織)의 상대결정화도(相對結晶化度)는 각각(各各) 23%와 35%로 다소(多少) 차이(差異)가 있었다. 3. 미결정(微結晶)의 폭(幅)은 1차조직(次組織)과 2차조직(次組織)과의 차이(差異)가 없었다. 4. 1차조직(次組織)의 미결정(微結晶)의 배향(配向)은 무배향(無配向)을 나타냈지만 2차조직(次組織)의 미결정(微結晶)은 섬유축(纖維軸)에
The fine structures of the Primary and the secondary tissues in Pinus densiflora were examined by X-ray diffraction method. The results obtained are summarized as follows; 1. D-spacings of (200) and (004) Planes had little difference in both tissues. 2. The crystallinity index of the primary tissue as observed was 23%, while that of the secondary tissue was 35%. 3. The lateral crystallite size of both tissues had almost equal values. 4. The crystalline substances of the primary and the secondary tissues showed different patterns of orientation. The former had a random orientation, whereas the latter showed an orientation of 20 to 25'.
