The adantages of dual grafts for bridging defects are as follows:(1) mechanical fixation is better than fixation by a single onlay bone graft;(2) the two grafts add strength and stability;(3) the grafts form a trough into which cancellous bone may be packed; and (4) during healing the dual grafts, unlike a single graft, preent contracting fibrous tissue from compromising transplanted cancellous bone.

双侧植骨桥接骨缺损的优点包括：①机械固定作用比单侧贴附植骨更好；②双侧植骨可增加强度和稳定性；③双侧的植骨可形成一骨槽，可在其中压紧松质骨；④与单侧植骨不同，双侧植骨在愈合过程中可防止挛缩的纤维组织危害移植的松质骨。

The main driver is to take induction sealing into areas where induction was previously not an option, areas where a traditional conduction seal was applied to a container where there would be no closure, or maybe just a light overcap, such as foil-sealed, single-serve products, yoghurts, single-dose -probiotic drinks, airline water cups and Pot Noodle-type snack foods.

的主要驱动力是采取密封感应到的地方感应以前不是一个选项，地方传统传导密封适用于一个货柜的地方就不会有封闭，或也许只是一个轻overcap ，如铝箔密封，单服务，产品，酸奶，单一剂量的益生菌饮品，航空公司水杯子和锅面式小吃。

A novel kind of oligomer PPV derivative containing oxadiazole in the main chain was synthesized according Heck reaction, efficiency of single layer OPPV device was about five time higher comparing with single layer PPV device, which was attributed to the improved, balance of carrier injection and transportation.

三、利用Heck反应合成了PPV主链上含有恶二唑基团的可溶性低聚物OPPV，OPPV的单层器件的效率较单层PPV器件的效率提高5-10倍，证明了单层器件亮度和效率的提高是载流子平衡注入和传输的结果。

Three single crystals of N-nitrobenzene, N-acyl dehydroabietic hydrazine 7c single water compounds, N, N-acyl dehydroabietic hydrazine 7l and 2,5 - dehydroabietic-1, 3,4 - oxadiazole 8g were obtained for the first time. X-ray diffraction analysis of these crystals showed dehydroabietic acid skeletons were contained in these crystal molecules.

The presumption that new technology about distillation column with a single reactor can be used in photochlorination of acetic acid is first proposed in this paper. The fact that reaction distillation has obvious advantages in the number of theoretically perfect trays and energy consumption was obtained by theoretical analysis between the coupling of reaction and distillation and the independent operation, which lays a theoretical foundation on the application of the distillation column with a single reactor in photochlorination of acetic acid.

本文首次提出了将背包式反应精馏耦合技术应用于乙酸氯化反应的设想，通过对反应精馏耦合和反应精馏独立操作两种情况进行理论分析，发现反应精馏耦合在理论板数、能耗方面均具有明显优势，因而为背包式反应精馏应用于乙酸光氯化反应奠定了理论基础。
