However, as the concentration increased to 100~400μg/mL, the micronucleus ratio significantly rose, while the karyokinesis index significantly decreased.

浓度升高到100~400μg/mL时，细交链孢菌酮酸使蚕豆根尖细胞微核率显著升高，有丝分裂指数显著下降，其中，400μg/mL时，微核率高达36.01‰，有丝分裂指数仅为1.90%。

Results: The PCNA mean labelling index was 48.84％± 13.63％, and the apoptotic labelling index was12.26‰± 5.20‰. The Kaplan-Meier survival curves showed that the postoperative survival time of the patient was shorter when the tumor infiltrated to the adventitia of esophagus,with lymph node metastasis, without keratinization, PI ≥ 40％ or AI＜10‰. Using forward multivariate Cox regression analysis, only the parameters of pN category and PI could be verified as independent prognostic factors.

结果：36例手术切除的食管鳞癌组织平均PCNA表达指数(PCNAlabellingindex，PI)为48.84％±13.63％，细胞凋亡指数(apoptosisindex，AI)为12.26‰±5.20‰；PI升高与患者年龄小、分化程度低、有淋巴结转移和肿瘤进行性浸润呈正相关，而AI升高与分化程度高、角化明显呈正相关；绘制Kaplan－Meier生存曲线，发现病变侵及食管外膜、有淋巴结转移、无角化、PI≥40％或AI＜10‰的患者术后生存率明显降低；COX比例风险模型分析，发现只有淋巴结转移和PI是影响预后的独立因素。

It is well known that a resolvable maximum packing with triples of order v with index λ=1 is a nearly Kirkman triple system KTS if v≡0 (mod 6), so the whole embedding problem for resolvable maximum packings with triples for arbitrary index λ has been completely solved.

由于指数λ=1且v≡0（mod 6）时一个v阶的可分解最大填充三元系即为一个v阶的拟Kirkman三元系，所以对一般指数λ的可分解最大填充三元系的嵌入问题已全部解决。

by calculating the rca of guangxi in recent years and its ntr index of 2006, the author comes to the conclusion: compared to other provinces in china, the superior industries of guangxi are mainly labor intensive industry and resource intensive industry; and food manufacturing industry, chemical industry and paper making industry are increasingly developing, which have become the new advantages in export; electromechanical products and hi-tech products of guangxi are inferior to those of other provinces in china.

文章计算了广西近几年的显性比较优势指数和2006年贸易竞争力指数，通过综合分析得出广西出口产业的比较优势格局：广西相对于全国具有比较优势的产业主要集中在资源密集型和劳动密集型产业，且部分产业的优势地位趋于减弱；近年广西重点发展的食品制造、化工、造纸等产业发展较快，已成为在全国具有强比较优势的出口产品；机电产品和高新技术产业处于明显的比较劣势地位。

In order to get the more accurate data of atmospheric capacity about this type of area, such as Yueyang, this paper analyzed the characteristics of Yueyang meteorology, gathered the features of atmospheric pollution sources, worked out the main problems in environmental protection. In addition, we analyzed the rule of atmospheric transport and diffusion, and took the Frequency of lake and breeze to modify the data of atmospheric capacity of Yueyang, which was achieved by A-P index, and compares the modified data of atmospheric capacity with the data of atmospheric capacity achieved by multi-source. The results indicated that according to the fact of lake and breeze, taking the frequency of lake and breeze to modify the data of atmospheric capacity of the field with stable lake and breeze, which is achieved by A-P index, made the atmospheric capacity more accurate. Accordingly, the result could be more reliable if the modified data is taken to calculate the atmospheric capacity when we assess the impact on the environment of the field with stable lake and land breeze.

为准确地求得这一类型地区的大气环境容量，本文研究了岳阳市城区大气环境的主要特点，收集大气污染源数据并进行分析，查明岳阳市城区主要环境问题，分析岳阳市城区主要大气污染物的迁移转化规律，对A-P指数法求得的岳阳市大气环境容量值用湖陆风频率进行修正，并将修正后的大气环境容量与多源模型(区域大气环境容量计算模型)求得的大气环境容量进行对比，得出结论：根据湖陆风环流情况下的大气扩散方式，对有稳定的湖陆风环流的地区，采用湖陆风频率修正A-P指数法求大气环境容量，进一步提高了计算的准确性。
