摘 要 以浙江省天台山七子花群落为研究对象，采用相邻格子样方法取样数据，应用方差／均值比的t检验法、负二项参数、扩散型指数、Cassie指标、丛生指标、平均拥挤指数和聚块性指数等方法，分析了七子花群落各优势种群以及七子花种群在各样地中的分布格局，并分立木级对七子花种群在不同样地内的集群强度进行了测定。

Since the number of trips is a non-negative integer, truncated, and of endogenous stratification, this study empirically analyzes its recreational benefits by the On-site Poisson and truncated negative binomial with endogenous stratification of the Travel Cost Method. Besides, this study adopts TNBES to see how the number of trips disperse and takes the consumer surplus to assess benefits. As to visitors' valuation, this research uses the ordered probit to do empirical analysis and then divides all satisfaction factors by the factor analysis and cluster analysis into four factors and two clusters, which then are taken as explanatory variables.

考量旅游次数为非负整数、截断、内生分层等特质，本研究在游憩效益方面，采旅游成本法中的现场波松(On-site Poisson)、截断式内生分层负二项(Truncated Negtive Binomial with Endogenous Stratification， TNBES)模型做实证分析，并於TNBES模型检定旅游次数之扩散情形，效益之评估采消费者剩余为计算标准；在游客评价方面，采次序波比模型做实证分析，并将游客对科博馆各项因素满意度以因素分析、集群分析，区分为四大因素构面与二大集群，纳入游客评价为解释变数，并探讨消费者剩余对游客评价之影响。

Through researching the mechanism of biological nitrification and denitrification and actual project application of the technology and related literature materials, the obtained results are as follows:(1) Anoxybiosis is effective to the removal of COD; after the anoxic process, BOD/COD of the outflow increases, it shows that the degradation ability of wastewater is improved; anoxybiosis is insensitive when shock loading of inflow wastewater varies greatly;(2) It is demonstrated by the operation of inoculation and cultivating that biofilm takes two weeks to succeed in cultivating on packings and the removal ratios of NH3-N and COD get 50% and 70% respectively, when gas-water ratio is 6:1, HRT is 7.3 hour, water temperature is above 15°C;(3) It is demonstrated that gas-water ratio, hydraulic loading, HRT, temperature, pH etc are important factors which influence the removal effect of pollutants, when the gas-water ratio is 6:1, hydraulic loading is about 0.38kgNH3-N/m~3.d, water temperature ranges from 15°C to 27°C, pH ranges from 7.5 to 8.0, the BIOFOR removal effect of pollutants is the best;(4) The operation indicated that, this technology has strong ability of nitrification and denitrification; it has extremely vital significance for reducing the water body eutrophication;(5) It is confirmed the feasibility and the usability of preanoxic-BIOFOR process to treat L-lactic acid production wastewater. The experiment indicated that the treatment effect of this technology is very good and also shows that the technology has many advantages, such as small volume, high treatment efficiency, good effluent quality and strong endurance to load variation, this technology is a new and economical wastewater treatment process.

通过对生物脱氮机理的研究和该组合技术的实际工程应用，并结合有关文献资料，取得如下结论：(1)预缺氧池对L-乳酸生产废水中的COD去除具有一定的效果；废水中难降解的高分子物质经过缺氧工段分解为易于氧化降解的物质，浮状有机物在水解菌的作用下，将不溶性有机物水解为溶解性物质；预缺氧池具有较强的抗冲击负荷能力；(2)BIOFOR接种挂膜过程表明：HRT为7.3h、气水比为6：1、水温保持在15℃以上，经过半个月生物膜即以形成，NH_3-N和COD的去除率分别达到50％和70％左右；(3)研究表明：气水比、水力负荷、HRT、温度、pH等是影响污染物去除效率的重要因素，在气水比为6：1，NH_3-N容积负荷为0.38kgNH_3-N／m~3·d，温度在15℃-27℃，pH在7.5-8.0之间的条件下，BIOFOR对污染物的去除效率达到最佳；(4)运行表明，该组合技术具有较强的脱氮能力，对于减少水体富营养化具有十分重要的意义；(5)经过半年多实际工程的现场调试与运行，验证了利用预缺氧—BIOFOR组合工艺处理L—乳酸生产废水的可行性和实用性，得出该组合技术具有占地面积小，处理效果好，运行费用省，耐冲击负荷能力强等优点，是一项新型、经济的污水处理技术。

Considering the merits of in vivo studies in biotransformation i. e. activation or inactivation, protein-binding such as sex hormone binding protein , toxicokinetics, and more evaluative in hazard identification and risk assessment, we selected a battery of short-term and long-term in vivo studies, including uterotrophic assay in weaning mice and ovariectomized adult mice, an in vivo multiple endpoints assay, and a gestational and lactational exposure assay to identify the estrogenic effects of endosulfan on the offspring.

考虑到体内试验在代谢转化、血浆蛋白如性激素结合蛋白的结合、代谢动力学等方面比体外试验优越，在危害鉴定和危险度评定中更有价值，我们选择了多项体内试验，包括对幼年小鼠和卵巢切除成年小鼠的子宫增殖作用、对成年去势小鼠的体内多终点观察以及大鼠孕期和哺乳期接触对雄性子代生殖系统结构和功能的改变，即去雄性化或雌性化作用等，来验证硫丹的体内雌激素样作用。

In the second study, interpersonal and social rhythm therapy was 1 of 3 intense psychotherapies that resulted in better outcomes than collaborative care, in a 1-year randomized study that was part of the Systematic Treatment Enhancement Program for Bipolar Disorder trial (Miklowitz DJ et al. Arch Gen Psychiatry 2007;64:419-426). A total of 293 outpatients with bipolar I or II disorder and depression treated with protocol pharmacotherapy were randomized to up to 30 sessions of intensive psychotherapy with 1 of 3 methods — interpersonal and social rhythm therapy, family-focused therapy, or cognitive behavior therapy — or to 3 sessions of collaborative care treatment. Compared with patients treated with brief collaborative care, patients receiving intensive psychotherapy attained remission of depression within a shorter time.

在第二项研究中，个体间与社会节律疗法是三种密集精神治疗中的一环，这些治疗的预后比联合照护好，这项研究是一项为期一年的随机分派研究，且是Systematic Treatment Enhancement Program for Bipolar Disorder试验的一部份（Miklowitz，等人Arch Gen Psychiatry 2007；64：419-426），总共有293位罹患第一或第二型双极性异常与忧郁症，且正在接受药物治疗疗程的门诊病患，他们被随机分派接受高达30次的密集精神治疗，分别是个体间与社会节律疗法、家庭疗法或是认知行为治疗，或是接受三次的联合照护治疗；相较於接受行为治疗照护的病患，接受密集精神治疗的病患达到忧郁症状消退的时间较快。
