Methods 300 cases (560 ears)of temporal CT axial images which were divided into two groups were retrospectively analyzed by statistics methods. There were 158 cases(316 ears)in normal group and 142 cases(244 ears)in abnormal group .The incidence of high jugular bulb , dehiscent jugular bulb, anterior location of sigmoid sinus, large sinus tympani, aberrant internal carotid artery, dehiscent of the facial nerve canal, excess of Korner's septum and mastoid antrum dysplasia were recorded.

The solutions were found to be good agrees with experimental results. The transfer characteristic of air dry/wet bulb temperature and spraying water temperature were discussed. The LMTD method based on this mathematical model is applicable to design and verify for the plate wet air cooler. The ratio of the wet bulb heat transfer coefficient to the heat transfer coefficient under air-cooled conditions was investigated theoretically and experimentally. The relative errors of the ratio between theoretical and experimental valves are small than 7 percent.

分别得到了平行流型式微分方程组的解析解与交叉流型式的近似解析解，实验验证了该解析解具有较高的计算精度；探讨了空气干湿球温度与喷淋水温的迁移特性；分析得到基于湿球温度迁移模型的对数平均温差法在湿式空冷器的设计与校核计算中是适用的，给出了空气湿球换热系数与空冷时空气对流换热系数比值的理论与实验确定方法，比值系数理论值与实验值比较最大相对误差小于7％。

Thunberg Fritillary Bulb is one of the most popular Traditional Chinese herbs. Some trials in vivo and animals indicated that Peimine and Peiminine, extracted from Thunbery Fritillary Bulb, have the function of reversing MDR of two different kinds of mechanisms. They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.

浙贝母是临床常用中药，体外及动物试验证明，浙贝母中的有效活性成分贝母甲素和贝母乙素具有逆转肿瘤细胞MDR的作用，而且能逆转两种不同机制的多药耐药肿瘤细胞的耐药性，在无明显细胞毒剂量下，可使阿霉素对耐药肿瘤细胞的杀伤活性提高5-10倍，不但具备明确的多药耐药逆转剂的特征，而且在化学结构上属异甾类生物碱中的瑟文类生物碱，完全不同于钙离子拮抗剂、免疫抑制剂和其它现有的耐药逆转剂，具有作用靶点宽、化学结构独特的特点。

METHODS: Olfactory bulb was sterilely collected from rats, digested, and centrifuged. After removal of the supernatant, the olfactory bulb was resuspended with DMEM/F-12 medium containing 0.2 volume fraction of fetal bovine serum. The diluted monoplast suspension was equally assigned into 3 samples, and separately used for simple modified differential adherence, simple serum-free conditioned medium, and modified differential adherence + serum-free conditioned medium.

The results showed that bulb height and flower size of 'Large Copper' were least, with longest white short soft hair on stem. Obvious characteristics of 'Toronto' were nacarat and lackluster membranous bulb scales, leaves with rufous stripe and base of perianth shape and colour. Obvious characteristic of 'Pink Impression' were taller plantlet, bigger flower, taller and wider leaves and edge of leaves with short hair.

结果表明：品种Large Copper的种球高度和花径均最小，茎上白色柔毛最长；品种Toronto的显著特征是种球的膜质鳞片为桔红色，无光泽，叶片上有红褐色条纹，花被片基部为黑色舌形；品种Pink Impression植株高，花大，叶片长而宽，叶缘有短毛。
