Since Wolf put up the trajectory algorithm to Lyapunov exponent in 1985, how to calculate the Lyapunov exponent with accuracy has become a very important question. Based on the theoretical algorithm of Zuo Binwu, the matric algorithm of Lyapunov exponent is given, and the results with the results of Wolfs algorithm are compared.
Lyapunov指数l是定量描述混沌吸引子的重要指标,自从1985年Wolf提出Lyapunov指数l的轨线算法以来,如何准确、快速地计算正的、最大的Lyapunov指数lmax便成为人们关注的问题,虽有不少成功计算的报导,但一般并不公开交流。

Based on fuzzy mathematics comprehensive evaluation, the toxicity of heavy metals was taken into account. The fuzzy comprehensive evaluation results by pollutant concentration exceeding standard weighting method, toxic response coefficient heck-stepping index weighting method and heavy metal toxicity sorting weighting method were compared with the potential ecological risk evaluation results. The research results showed that the evaluation results by toxic response coefficient back-stepping index weighting method could reflect the actual results more truly and accurately.

Three-factor Jensen model reveals that 82% of all the funds have positive alphas and half of these alphas are statistically significant. And also, the average of the sample funds' alphas and the alpha of the equal-weighted fund are both positive and statistically significant. These illustrate that the sample funds have excellent performance when size and style factors are considered.(4) The study shows that Chinese funds as a whole do not exhibit excellent skills for stock selection and market timing.
在三因素模型下,有82%的基金的詹森阿尔法大于零,正值詹森指数中的一半具有统计显著性,样本基金詹森指数均值及等权基金的詹森指数均为正值,且具有统计显著性,说明在考虑了规模和价值因素的影响后,样本基金表现优异;(4)对基金选股与择时能力的实证分析表明,中国基金在整体上没有显示出良好的预测市场走势的能力,也未显示出优异的选股能力。

The test groups were drenched orally with different dosages of compound Radix scutellariae granules. After being drenched orally for ten days, their thymus-index and spleen-nidex, immune globulins of IgA, IgG, IgM and alexins of C3, C4 of serum were defermined, and experiments in vivo were done. The mice-spleen's lymphocytes which were cultured in vivo were added with different concentrations of compound Radix scutellariae granules. The lymphocytes translation stimulate indexes were measured. The ability of licking up neutral red of the peritoneal macrophages cultured in vivo was measured in the groups.

Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.
结果加入PMA培养的哮喘组T淋巴细胞NF-κB的活化、细胞增殖反应、IL-4和IL-5的mRNA和蛋白质的表达均显著高于其空白对照(P.01),而同时加入PMA和PDTC培养的哮喘组T 淋巴细胞以上指标均显著低于只加入PMA培养的哮喘组T淋巴细胞(P.01);加入PMA 培养的哮喘组T淋巴细胞的凋亡指数显著低于其空白对照(P.01),而同时加入PMA 和PDTC培养的哮喘组T淋巴细胞凋亡指数显著高于只加入PMA培养的哮喘组T淋巴细胞(P 。01)。T淋巴细胞NF-κB的活化与增殖反应呈显著正相关(r=0.64,P.00 1),与IL-4和IL-5的mRNA和蛋白质的表达也均呈显著正相关(r=0.55-0.68,P 。001),而与凋亡指数呈显著负相关(r=-0.62,P.001)。
