Study on the Conservation of Ayutthaya Historic Site, Thailand

环境条件（空气温度、湿度、预测、绝缘强度、表面温度和砖内部）通过一个计算机控制的自动测量系统对Rajaburana模板进行了测量，其中电池有效。测量揭示了以下事实：·一年中的每日最大气温高于30摄氏度。雨下了很多雨，在雨季的尽头。彩虹在一天的短暂时间里集中在一起。按年份分列的每月平均温度和预测变化年份;运动内容的季节性变化越来越大，砖柱周围的地面被使用的模型结构测量了，其中一些已经在Maha建造的模型结构。“测量揭示了将Lime Mortar应用到一个砖柱表面上非常有效地减少了查理在柱上的运动内容。在砖中运送出的特定位置的玛哈，寺庙中的砖在十月里有很多砖。”构造中的水平面是由ccmputer使用模型等式分析的。就像结果一样，它揭示了雨水中心走向衰退的地方。因此，使建筑物顶部的防水材料被认为对减少这一现象产生了影响。所以，一个使用模型结构的实验已经过时了。而且它揭示了这个方法是如此的承诺。作为一个试点项目，MacNang Pluem的恢复已经完成。对网站的一般调查和参考研究揭示了，其中对水泥的确定性已经广泛地用于1960年代纪念碑的恢复现在已经成为一个大问题。苏呼泰历史网站的调查已经被作为相关研究进行了。Sukhothai历史性网站和Ayutthaya历史性网站在细节中与每个人有明显的不同。因此，对苏呼泰历史遗址保护的研究是必要的。

Environmental conditions (air temperature, humidity, precipitation, insolation intensity, temperature of surface and inside of a brick) were measured at Rajaburana temple by a computer-controlled automatic measuring system which works by batteries. The measurement reveals the following facts :・Daily maximum air temperature is more than 30℃ throughout the year.・ Rain falls much in the end of rainy season.・ Rainfall is concentrated in a short time in a day.・ Monthly average temperature and precipitation differ year by year.Seasonal change of the moisture content ill brick pillars and surrounding ground were measured by using model structures which had been built in Maha That temple. The measurement reveals that the application of lime mortar onto the surface of a brick pillar is very effective to diminish the charlie of moisture content in the pillar.Precise investigation and seasonal measurement of moisture content in bricks were carried out at the certain place of Maha That temple where bricks have been severely in decay. And the water regime in the construction is analyzed by ccmputer using a model equation. As the result, it reveals that rain water centers towards the decaying place. So, making the top of the construction waterproof was considered effective to diminish this phenmena. Thus, an experiment using model structures was curried out. And it reveals that this method is so promising.As a pilot project, restoration of Mac Nang Pluem have been done.General survey of the site and the bibliographical study reveals that the deterioration of cement mortar which is used widely for the restoration of monuments in 1960th is now becoming a big problem.Investigation of Sukhothai historic site was carried out as related study. Sukhothai historic site and Ayutthaya historic site are quite different from each other in detail. Therefore, study on the conservation of Sukhothai historic site is needed.
