There is an original relationship between traditional hakka residential architecture and the social histories and the regional natural environments at that time. The traditional hakka residential architecture in Meizhou is established on Nature worship, and keep in harmony with natural environments. For examples, the locations of bildings are in line with local conditions; the layouts and styles are usually based on the rule of south exposure and central axis symmetry; the structures lay stress on functions and comfort and harmony with local environments. Unreasonable artificial alteration, for example, cutting slope and building house under the slope are usually triggers landslides, collapses and other geological disasters, and it has become the most dangerous and latent factor to the geological disasters. The ecological environment idea of the traditional hakka residential architecture in Meizhou region has still certain referential significance for modern residential architecture.

实证应用分析研究表明，梅州客家传统民居建筑与当时的社会历史背景、区域自然环境因素之间存在着密切关系；客家民居建筑渗透出尊重自然，与自然环境融为一体的生态环境理念，具体表现为选址上做到因地取舍与回归自然相统一，布局上讲究座北朝南与中轴对称相结合，建筑上注重实用舒适与环境氛围相融合；不合理削坡建房常常诱发崩塌、滑坡等地质灾害，成为地质灾害发生的最大潜在因子；梅州传统客家民居建筑的生态环境理念对现代民居建筑仍然具有借鉴与启示作用。

Such as the West Fourth Ring定慧寺the乐府江南bridge, combined with the geographic location of natural advantages, the design of the garden, to absorb China's Jiangnan garden style of gardening techniques and the experience of the North, to build the capital charm unique, scenic spots occur repeatedly landscape south of the Yangtze River, in the master plan for 300,000 square meters of land, there are nearly 10 more than 200 30 ~ 100 years of natural trees scattered into the garden, including gingko, cedar, gold tree, acacia, Pentagon Maple and so on.

如西四环定慧寺桥的乐府江南，加上地理位置优越的自然条件，设计中的花园，吸收中国的江南园林风格的园艺技术和经验，北至首都建设魅力独特，风景名胜区不断发生的景观江南，在总计划的30万平方米的土地，有近10 200多名30 100年的自然树木散布到花园，包括银杏，雪松，黄金树，台湾相思，五角大楼枫树等。

By the introducing the concept of embodied alterity as the original experience of religion, Thomas Csordas asserts that 'outside of horizon' will be the most essential resource of religious experience, that, according the views of French post-structurism, religious feeling pour out involuntarily.

本研究采用宗教现象学的取向，借重Thomas Csordas的引介，将异己性（他者性，alterity）作为圣世界的经验溯源，而以乔治巴塔耶的宗教理论为主要的发展核心，试图从实徵与理论两个层面包抄，发展癌末处境的圣世界之内涵，其中最具关键的问题在於(1)圣世界经验的发生应先排除语言的干预，使圣世界的发生完全在真切经验自然涌出：(2)圣世界经验的源头应为「域外」，那是非领域、非知，因此，研究问题遂在於「域外何以发生」；(3)圣世界的形成，本质上被假设为「异质跳接」，所以圣世界的复合逻辑应是由常人、医疗、宿缘以及无缘他者四者的逻辑平面交叠、挤压而形成多重皱摺，本研究试图通过病房田野，以实徵资料解明复合逻辑的内涵。

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。

Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.

结果表明不同肺炎链球菌株的转化最适菌密度不同，1、2和22号菌株的最适转化密度分别为0.1、0.08和0.07；用于转化的CTM培养基最适为pH 8.0的C+Y培养基；在自然转化下不能诱导转化发生的pH 6.8的C+Y培养基中，使用CSP诱导，也能促使细菌发生转化，只是转化效率较低；结论：实验室条件下，不同细菌在一定菌密度时可利用CSP诱导肺炎链球菌成为感受态发生转化。2、为探讨肺炎链球菌转化对毒力表达的影响，本研究分别通过体外粘附人脐静脉血管内皮细胞ECV-304和体内小鼠毒力实验观察1、2和22号肺炎链球菌和其转化缺陷菌株1t、2t和22t毒力的差异。
