Multiple respiratory gas monitoring causes changes of inspired oxygen concentration in closed anesthesia system

This case report describes an accessory hepatic duct (AHD) identified by intraoperative cholangiography during excisional surgery of a choledochal cyst (CC). The accessory duct was divided and reconstructed successfully to the Roux-en-Y jejunal loop. The postoperative course was uneventful, and follow-up abdominal sonography revealed neither evidence of biliary tract obstruction nor atrophic changes of the liver. It is advocated that an AHD should be meticulously reconstructed if it is divided during excisional surgery of a CC.     

氧化还原功能纤维的研究 Ⅷ．含正丙胺基吸附剂与Au~（3＋）的氧化还原反应机理

通过元素分析、红外光谱分析、光电子能谱分析以及扫描电子显微镜分析等手段，证实含正丙胺基吸附剂与Ａｕ３＋的氧化还原反应过程中，氮原子邻近的羟基碳或Ｃ－Ｈ键被氧化，而氮原子并未参与氧化还原反应；吸附态Ａｕ（３＋）最终部分被还原成单质金；在非水介质中吸附在吸附剂上的金聚集成颗粒状。     

线加权余量法及其在正交异性板弯曲分析中的应用

利用有限差分法对控制方程和边界条件进行半离散化,使其定义在一些离散线上,然后采用加权余量法求解。这就是本文提出的线加权余量法,也可称之为有限差分-加权余量分维耦合法。文中以正交各向异性薄板弯曲平衡问题为例推导了有关具体算式,给出了数值算例,说明了本文方法的有效性。     

机械合金化Fe50Ti50非晶的形成及球磨强度对它的影响

本文通过电子扫描和Ｘ衍射对机械合金人Ｆｅ５０Ｔｉ５０非晶粉末形成做了研究。研究发现：机械合金非晶形成可以大致地分为二个阶段－粉末的破碎阶段和非晶的形成阶段。另外，对球磨强度对非晶形成的影响进行了研究。结果表明：强度低时粉末需要较长的时间才能形成非晶，强度高时粉末形成非晶的时间大大缩短，但在随后的球磨中，粉末会重新晶化形成新相。

Reynolds number-dependent permeability of wastewater sludge flocs

Most theoretical models assume constant permeability of wastewater sludge floc. This work shows that, at creeping flow limit with small intrafloc Reynolds number, the permeability of floc can not only be affected by floc structure, but also by the external flow condition. The three-dimensional structure of flocs using the fluorescence in situ hybridization (FISH) and the confocal laser scanning microscope (CLSM) was firstly probed. Then, the volumetric grid models for sludge flocs were constructed. We noted that the floc permeability could keep unchanged, increased, or decreased at increased Reynolds number (Re). Flow redistribution among channels of various sizes contributes to the noted Re-dependent permeability of flocs.
