In conclusion, the results of multilevel model analysis showed that the GERD score of resident in Wuhan was relatively higher and had significant difference with that in Guangzhou, however, that in Shanghai, Beijing and Xi\'an had no significant difference compared with that in Guangzhou. That is to say, the prevalence of GERD in Wuhan was relatively higher compared with the other four survey sites; the residents'health status more worse, the GERD score more higher, and the influence of health status on GERD score was also effected by the region difference between Wuhan and Guangzhou; residents lived in rural region with lower education level, worse spirit status were more likely to suffer from GERD; Moreover, those residents who had family history of GI tumors or other GI diseases, some anamneses (such as dyspepsia, gastritis, rheumatic arthritis), and some diseases (such as irritable bowel syndrome and aerophagia) were also more likely to report GERD. However, no significant association was found between GERD and some other factors in this survey, such as sex, age, etc.

总之，多水平模型分析结果显示，与广州相比，上海、北京和西安居民的GERD总评分没有明显的差异，而武汉居民的GERD总评分则相对较高，即表示武汉的GERD发病率在5个调查城市中相对较高；居民的总体健康状况越差，其GERD总评分越高，且其对GERD总评分的影响受到武汉与广州之间地域差异的影响；农村居民、文化程度越低、精神状况越差者更容易患GERD；另外，那些有胃肠道疾病或肿瘤家族史，既往患有胃炎、消化不良、风湿性关节炎，现患有肠易激综合征、吞气症的人，患GERD的可能性更大，而性别、年龄等因素，本研究未发现其与GERD有显著的关系。

The biographic characteristics have some effects on the performance of the top managers, but it is not obvious enough. Therefore, it is suggested the enterprises should consider the implicit value as the incentives to the top managers.

基于学习与成长等隐性需求的激励对绩效的影响比基于物质报酬等显性需求的激励对绩效的影响更大；个人传记特征对企业高管人员的绩效有一定的影响，但整体上不太显著。

We noticed that the elements in Buddhistic cognitive model are more essential than those in the behavioral science.

心理学或行为科学中最核心的部分也在於「认知」原理，由此亦衍生出许多实用的知识，对精神医学、教育学、哲学、经济学等均有重大的影响，不只是人类的历史、现在的行为，甚至会对人类的将来有更深远而有力的影响。

Results showed that TDI induced toxic action on spermatogenic cell,while the chondriosome was its target within the length and concentrations.

结果表明：在本实验染毒时间和染毒剂量范围内，TD I对雄性的生殖毒性主要表现为对各级生精细胞均有一定的毒性作用，作用的靶点是细胞内的线粒体；TD I通过影响各种酶的活性，干扰了睾丸组织的有氧代谢和无氧供能，抑制了细胞对能量的利用，损伤了各级生精细胞，导致生精上皮不可逆的损害，从而造成了其对雄性生殖系统的损伤；TD I对雄性生殖细胞的核酸代谢以及DNA合成有一定影响。

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

In the simulated experiments, the effects of long-term exposure of dibutyl phthalate on contents of malondialdehyde, solubility carbohydrate, blade pigment, protein, glutathione and amino acid of Vallisneria spiralis L were studied. The cultivation period was 25 days. The effects on the growth of Vallisneria spiralis L under the stress of DBP was also invertigated in this paper. Vallisneria spiralis L was damaged seriously in long-term exposure of high concentration DBP.

以沉水植物苦草为试验材料，通过模拟实验研究了邻苯二甲酸二丁酯长期暴露对苦草的生长状况以及丙二醛、可溶性糖、叶绿素、谷胱甘肽、蛋白质和氨基酸的含量等生理生化指标的影响，试验结果表明：高浓度DBP长期暴露对苦草生长有严重伤害，DBP对苦草丙二醛和可溶性糖含量以及叶片中叶绿素含量的影响比较相似，都有一定的起伏。

Since 2000, the project I had/have been responsible for include:Health Effects of Fine/Ultrafine particles in ambient air of Beijing founded by Natural Science Foundation China and also cooperated with GSF, Germany; Energy Selection and Health Benefits in Beijing and China funded by IES program of USEPA, Study of Environmental Cost Model in China funded by USEPA, Risk Assessment for health Effects of Biological Indoor Air Pollutants and outdoor air pollution funded by China Ministry of Science and Technology; Health Effects of Fine Particles from the Dust Storms in China funded by NSFC and also cooperated with NIER, South Korea, etc.?

Currently, vitamin prices have jumped has a very small space, the key is how long it can maintain a state of high prices, which will be subject to two factors, on the one hand, the domestic raw material prices of the leading business-to-vitamin weak, if the international correlation Game industry inversion occurred, the performance of domestic enterprises will also be affected, on the other hand, feed the downstream industries affected by the economic downturn, demand for vitamins, but also will affect the performance of the company.

目前，维生素价格上涨有一个非常小的空间，关键是如何能长时间保持高价格，将会受到两个因素一方面，国家，国内领先的业务原材料价格上扬维生素弱，如果国际相关游戏行业反转发生后，国内企业的业绩也将受到影响，另一方面，饲料受经济衰退影响的下游产业，对维生素的需求，而且会影响性能公司。

The result also showed the psychological support can remarkably boost prentices' organizational commitment, but the function on job performance was divided into direct effect and indirect effect, namely the organizational commitment had the mediation effect to the relationship between psychological support and job performance. Besides, the career support had feeble direct effect on prentices' turnover intention, and the psychological support worked on prentices' turnover intention totally via the organizational commitment.

结构方程模型检验的结果显示，师徒关系中的职业支持和心理支持都对徒弟的工作绩效存在着显著的正面影响，其中职业支持对徒弟工作绩效的直接影响作用更大；心理支持对徒弟的组织承诺有显著的预测作用，而对徒弟的工作绩效的作用，一部分是直接效应，另一部分则是通过组织承诺来实施的；职业支持对徒弟的离职意愿只存在着薄弱的直接效应，心理支持则是完全通过影响徒弟的组织承诺来影响徒弟的离职倾向。
