• The statical fundamental equations for the dry system of nearly spherical granular materials were derived on the basis of the analysis of interactions between two particles. Compression tests were made and compared with the theoretically derived formula of compression. Moreover the aspects of the surface of particles were observed with a microscope. Then the following conclusions were obtained. 1. The interactions in the imagined models of particles hold for the actual granules. 2. The interactions are represented by ω=b_mP^<1/m> with the displacement ω and force P ; m changes as 3→2→1 for the actual granular systems. This is due to the plastic deformations of asperities and the bodies of particles. 3. The formula of compression derived here coincides with those proposed so far.
