摘　　要：我们研究了材料在稀疏区的相互作用势,并提出了一个新的势形式,相应的冷压形式只有一个待定参数,它由常压声速来确定,所得的冷压曲线与常态、断裂、常压熔点以及临界点等条件下的冷压符合程度是令人满意的。We studied the equation of state at temperature T=0 K and density ρ≤ Pa. A new potential form for the cold pressure is presented. The only parameter in the cold pressure formula can be determined via sound velocity C0.The cold pressures obtained from this cold pressure formula are in accordance satisfactorily with those deduced semiempirically normal conditions, from fracture and normal pressure melting point, as well as from critical point.
