There are rithics Not Reported though it is extremely important material for doing the comparison study of the microblad stone component. Executing those basic arrangement work, description work, and work of making to figure, and reporting on the result are our first purposes.In the study period of 3 years, we also ended the computer input of positional data and the classifying data of 159, 893 pieces of Motomachi 2 site of Bihoro-cho in Hokkaido. As a result, we were able to understand the rithic concentration parts and each rithic composition of 39. Afterwards, stone tools of 1200 pieces necessary to explain them was extracted and work of making to figure, the description work, and making the distribution chart of the rithic concentration part were completed at the same time, too.The-execution of the presumption of the use and of the identification of the method of flaking off the microblade is our second purpose.About the identification of the method of flaking off the microblade ; it made repeated experiments with the machine of flaking off by the oil pressure method that the head investigator had designed. As a result, it succeeded in being able the reproduction of flaking off about two types among the microblade technologies of three types that existed in these rithic groups, and catching the pressurizing power by the numerical value. The reproduction of the remaining one technological type is being continued now.Moreover, about the presumption of the use of the microblade, the observation with the microscope in 26000 pieces or more is being continued. The measurement of length, width, and the thickness of these pieces have already ended 98%, and these observation result of the microscope and a unified overall examination are scheduled to be done in the future.

虽然它是进行微叶石组分对比研究的极其重要的材料，但也有未见报道的材料。在为期3年的研究中，我们还完成了北海道Bihoro-cho的159,893块Motomachi 2遗址的位置数据的计算机输入和分类数据的计算机输入。因此，我们能够理解碎石集中的部分和每个碎石的组成39。然后，提取了1200件石器进行解释，同时完成了碎石集中部位的图形制作、描述工作和分布图的制作工作。第二个目的是执行微刀片剥离方法的推定和鉴定。关于微刀片剥离方法的鉴定，用首席调查员设计的油压法剥离机进行了反复的实验。因此，它成功地再现了存在于这些石器群中的三种类型的微叶片技术中的两种类型的剥落，并通过数值捕捉到了加压功率。剩下的一种技术正在继续复制。此外，关于微刀片使用的推定，26000件或更多件的显微镜观察仍在继续。这些碎片的长度、宽度和厚度的测量已经结束了98%，这些显微镜的观察结果和统一的全面检查计划在未来进行。
