Dehydration process based on hollow fiber composite membrane is one of the crucial and effective methods to remove water vapor from industrial gases such as light hydrocarbon, compressed air, natural gas and so on. Dehydration of propylene with VP method was studied in the thesis. We prepared the PVA/PS、CS/PS and PVA-CS/PS hollow fiber composite membranes by spread method. The permeation behavior of water vapor among coagulable light hydrocarbons through composite membranes and asymmetric membrane was researched by vapor permeation method. Also a differential mathematical model was established which can describe dehydration of gas phase propylene.

本论文以采用蒸气渗透法脱除丙烯中微量水分为目标，制备了 PVA/PS、 CS/PS、PVA-CS/PS 中空纤维复合膜；研究了可凝性轻烃蒸气中的微量水分在复合膜、非对称膜中的渗透行为，建立了描述丙烯气相脱水的数学模型，并进行了模拟计算；深入探讨了水蒸气在交联 PVA 致密膜中的渗透机理。

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.

本研究之目的在评估与工研院生医中心合作发展出可吸收性去乙醯几丁聚醣/胶原蛋白复合之组织导引再生膜片，并选择与可吸收性之BioMend Extend 及Peri-Aid 胶原蛋白膜片，和GORE-TEX OSSEOQUEST 合成高分子膜片，及不可吸收之GORE-TEX e-PTFE合成高分子膜片，等其他四种市售商品材料共同对照评估，应用8只年龄为12个月的雄性小猎犬，均分4组(分别为7天、14天、28天、3个月)，为动物活体评估模式，在实验犬之左、右下颚第一、二小臼齿及大臼齿的颊侧区制造骨缺损后，分别植入组织导引再生膜片，依实验设定时间将小猎犬牺牲，取下缺损区骨头，以光学显微镜观察量测其牙垩质再生高度与齿槽骨再生高度之变化，以探讨其组织再生模式及评估新膜片在临床应用之适用性。
