Methods Autologous BMMSC of New Zealand rabbits were acquired and induced into chondrogenic differentiation by adding transforming growth factor-β1 (TGF-β1), dexamethasane and ascorbic acid in vitro. Then the chondrocytes were implanted onto novel polymeric scaffolds made by Poly (dl-lactide-co-glycolide) embedding with chitosan nonwoven cloth. The tissue engineering cartilaginous grafts composed of chondrogenetic BMMSC/scaffolds were finally transplanted into the defects of ear cartilage in rabbits of the experimental group.

取新西兰大白兔BMMSC体外培养扩增，以含转化生长因子(TGF-β1)、地塞米松和维生素C的培养液做诱导培养，实验组以诱导后的软骨细胞与聚丙交酯－乙交酯共聚物Poly(dl-lactide-co-glycolide)包埋甲壳胺无纺布的新型支架形成复合物修复兔自体耳廓软骨缺损；对照组以PLGA/甲壳胺无纺布支架修复兔耳廓软骨缺损。

In this way, the Nonmonotonic Semantics (NM-Semantics) of DL+log is extended to the Nonmonotonic Circumscriptive Semantics (NMC-Semantics), and therefore, DLclog becomes the hybrid system with the stronger expressiveness and reasoning abilities.

使用这种方法，DL+log的非单调语义(NM-semantics，简称NM语义)被扩展成了DLclog的非单调限制语义(nonmonotonic circumscriptive semantics，简称NMC语义)，从而成为目前表达能力和推理能力最强的杂合系统。

A simple, selective and sensitive method was investigated for simultaneous determination of anions (SO2－4, Cl－, NO－3, F－) and cations (Na＋, NH＋4, K+, Mg2＋, Ca2＋) by single-column ion-exclusion-cation-exchange chromatography with conductometric detection. DL-malic acid-methanol-water was used as an eluent.

采用单柱离子色谱系统和电导检测的方法，首次以DL-苹果酸-甲醇水溶液为淋洗液，简便、有效地同时分离、检测了溶液中SO2-4、Cl-、NO-3、F-、Na+、NH+4、K+、Mg2+、Ca2+9种离子。
