方法选用血管蒂较长和血管口径较粗的游离组织瓣供区，选择口径粗大和位置合适的受区血管，将游离瓣制备成外露瓣，以利于术后血供的监测，在手术放大镜下行血管吻合，部分病例同时吻合2根静脉，以确保游离瓣的静脉回流。

Thermochemical Hole Burning memory uses the STM heating effect to induce a localized thermochemical decomposition of Charge Transfer Complexes, evolving the low-boiling point donor component and creating nanometer-sized holes on the crystal surface. In this thesis, we focus our research on the material synthesis and storage mechanism of THB memory.

热化学烧孔(Thermochemical Hole Burning，THB)技术是基于STM的超高密度信息存储技术，它利用STM针尖产生的隧道电流或场发射电流的焦耳热效应，诱导二元电荷转移复合物材料发生局域热化学气化分解反应，使低沸点组分从样品表面逸出，形成纳米尺度的信息孔。

供体切取范围包括腹主动脉(上至腹腔动脉以下，下至左肾动脉下方约0.8cm)、左肾、左肾动静脉、左输尿管，部分膀胱。

Compared with low resolution results of HLA-DRB1 alleles,high resolution results were analyzed to see any correlation between HLA-DRB1 alleles and GVHD. by double-blind statistically analysis of HLA-DRB1 high resolution in 48 donor/recipient typings in UCBT.

利用盐析或柱提法提取48例非亲缘性脐血及移植患者全血DNA，采用HLA-SBT方法分别对HLA-DRB1等位基因进行高分辨分型，并与HLA-SSP（HLA-sequencing specific primers）低分辨结果进行比较分析。

Theoretical calculations on a series of N-H…O=C hydrogen bond trimers were carried out using the MP2 method. We investigated the effect of substituents in hydrogen bond donor molecules on their hydrogen bond strength.

使用MP2方法研究了氢键三聚体中N-H…O=C氢键强度，探讨了氢键受体分子中不同取代基对N-H…O=C氢键强度的影响。

Arylselenoureas with electron donor group on benzene ringreacted with excess sulfinyl chloride to give 2-aminobenzosele-nazoles.
