项目摘要

In order to understand the natural phenomena in the earth (i.e., generation, transportation and fractional crystallization of magma, formation of various metamorphic rocks, etc.) high pressure experimental study is very important in earth sciences. Piston-cylinder is a standard high pressure apparatus because of its stability, precise pressure calibration, relatively easy handling, etc. Even though the PC (piston cylinder) apparatus is already established in the basic machine design, it is not easy to start a high pressure experimental laboratory because 1) PC apparatus is expensive (currently a full set PC would cost as much as 10,000,000 yen), 2) the PC is heavy and bulky (most machine is over 1000 kg and more than 1x1x1m in size), 3) the hydraulic unit and electric unit is difficult to use at least in the beginning.In order to facilitate the use of piston-cylinder apparatus in earth science laboratories which have not used to the experimental studies, we developed two types of small … More piston-cylinder apparatus with low cost, small size and weight, and very easy operation. The A-1 apparatus is capable of carrying out experiments to 3.0 GPa under room temperature and 2.0-2.5 GPa at high temperatures (100-1600。C). The A-1 apparatus has 1/2 inch diameter pressure chamber and 50tom force hydraulic ram. Its weight is only 95kg and 0.29x0.5x0.2m in size. The pressure can be monitored and controlled up to 0.2% of the full scale. Cost of a full set of A-1 including the heating device is approximately 3,000,000 yen). We developed another machine ; K-2 type with 100 ton force hydraulic. The K-2 apparatus is capable of carrying out experiments to 2.5GPa under room temperature and 1.5-2.0 GPa at high temperatures (100-1600。C). The K-2 apparatus has 3/4 inch diameter pressure chamber. Its weight is only 165kg and 0.33x0.64x0.2m in size. The pressure can be monitored and controlled up to 0.2% of the full scale. Cost of a full set of K-2 including the heating device is approximately 4,000,000 yen). Less

为了了解地球上的自然现象（即，岩浆的产生、输送和分离结晶，各种变质岩的形成等）高压实验研究在地球科学中具有重要意义。活塞缸是一个标准的高压设备，因为它的稳定性，精确的压力校准，相对容易处理等，即使PC由于PC（活塞缸）装置在基本的机械设计中已经建立，因此不容易启动高压实验室，因为1）PC装置昂贵（目前一台完整的PC机将花费高达10，000，000日元），2）PC机笨重（大多数机器超过1000公斤，尺寸超过1x 1x 1 m），3）液压单元和电动单元至少在开始时很难使用。为了方便活塞的使用-针对地球科学实验室尚未用于实验研究的圆柱装置，我们研制了两种小型圆柱装置， ...更多信息成本低、体积小、重量轻、操作非常简单的活塞-气缸装置。A-1型实验装置能在室温下进行3.0 GPa的实验，在高温（100-1600 ℃）下进行2.0-2.5 GPa的实验。C）。A-1型装置有1/2英寸直径的压力室和50汤姆力的液压顶。它的重量只有95公斤，尺寸为0.29x0.5x0.2米。压力可被监测和控制至满量程的0.2%。包括加热装置在内的全套A-1的费用约为3，000，000日元。我们开发了另一种机器; K-2型100吨力液压。K-2型实验装置能在室温下进行2.5GPa的实验，在高温（100-1600 ℃）下进行1.5- 2.0GPa的实验。C）。K-2仪器有3/4英寸直径的压力室。它的重量只有165公斤，尺寸为0.33x0.64x0.2米。压力可被监测和控制至满量程的0.2%。包括加热装置在内的全套K-2的费用约为4，000，000日元）。少
