柳喆模,柳京燮 忠州大學校 1972 한국교통대학교 논문집 Vol.5 No.-
A bubble-cap tray is used in the gas-liquid contacted operation of distillation and absorption, but as a lot of cost of manufacture and repair is required, I made use of a perforted plate of the cheap distillaton plate. I have experimented the bubble cap tray, the sieve tray and the valve tray comparing them with each other. The result is as following. (1) A good effect has becn obtained even if the perforated plate is used without using the bubble cap tray in the ditillation tower. (2) The efficiency of a pipe tray is almost the same as that of the valve tray and the sieve tray. (3) The dry pressure drops in a pipe tray were calculated by the equation(2).

線과 polyester에 各各 有用한 防炎劑는 많이 알려져 있으나, cotton-polyester 混紡에는 아직 利用하지 못하고 있다. 이런 難點은 物理的 性質과 防炎劑의 mechanism을 糾明하지 못한데 있다. 最近 線에 浸透하는 THPC-urea를 석어 쓰는 方法과 線과 polyester의 表面을 덮어주는 poly, (Vinyl Bromide) 最近 性能이 認定되는 Fyrol 76等을 使用하는 耐洗濯性이 좋은 防炎加工法에 對해 論하고자 한다.

Gas分析에 依한 變壓器 內部異常 草期發見에 關한 硏究
柳京燮,蔡萬秉,宋瑋憲,張香東,洪壯厚,沈鶴輔,柳喆模 서울産業大學校 1976 논문집 Vol.9 No.1
For the development of reliability of electric Power supply. It is very important to Predict the internal troubles of the transformer on load as We prevent the accident previously to try the trouble shooting. We have the testing results by gas chromato graph as following Occasion; a) We can predict that H₂CH₄ generated from insulating oil is the symptom of over heated coil produced. b) We can predict that a lot of C₂H₂ and H₂ generated from insulating oil is the symptom of the insulation trouble and pyrolysis of insulating oil by are occured. c) In the case of CO₂ and CO is generated from transformer's insulation oil is the sign of insulation material for example press board and phenol resin over heated.
