Interspecies hybridization and backcrossing is a means to transfer desirable genes from one species to another in breeding programs of higher plants. Monosomic alien addition lines can be produced via addition of single chromosome of an alien donor species to the entire chromosome complement of the recipient species.

在高等植物中，以种间杂交和回交把有益基因从一个物种转移到另一个物种为目的育种项目中，单个外源染色体常常被附加到含有受体细胞完整一套染色体中，形成异源单体附加系。

Firstly, a series of organic molecules which use phthalimido group as electron acceptor, N as electron donor, COO~- as eletrofugal group were synthesized based on SET-promoted photocyclization processes. These compounds were irradiated by 500 W ultraviolet under nitrogen atmosphere in room temperature. After filtration of the photochemical character of these molecules, substrate S1 and S2 were selected as appropriate model reactants. Secondly, the monosubstituted derivatives at the 6-position ofβ-cyclodextrin were synthesized as chiral template of photocyclization.

首先，以单电子转移机理为指导，设计了一系列以邻苯二甲酰亚胺基为电子受体、N为电子给体、羧基为离去基团的光环合反应底物，这些化合物在氮气保护下以500瓦紫外光室温下进行光照反应，对这一系列的分子的反应情况进行了研究与筛选，最终选择底物S1和S2作为研究光环合反应中立体控制方法的模型底物；其次，又合成了一系列6-位单取代β-环糊精，以此作为光环合反应的手性模板。

On the other hand, N-acylsalicylhydrazidate which contains several donor atoms is a strong chelating agent and is particularly well suited for the preparation of multinuclear complexes, In this paper, two N-acylsalicylhydrazidate ligands and six relevant complexes were synthesized.

本学位论文中，作者以水杨酰肼为原料合成了两个N-取代水杨酰肼配体和六个金属配合物。

Previous documented "local flaps", such as the peroneal or the gastrocnemius musculocutaneous flap, may produce significant donor site morbidity, recipient site bulky deformity, or may be technically difficult.
