火山石来自地壳深处，由于地壳深处的温度极高，火山石以火山岩浆的形态存在，随着火山喷发，岩浆也随之喷出地表，遇到水或低温开始凝结，凝结的过程由于空气的进入，逐渐变成固体的岩浆在内部形成了大量的气泡，完全凝固后就形成了构造独特的火山石。

In this paper, the connectivity axiom and the continuity axiom in Von Neumann-Morgenstern Rational behavior axioms are weakened. Then, a set of axiom for lattice ordered decision-making behavior, which can describe the decision-making behavior more rationally, is constructed. At last, the relative unique existence theorem for utility function is obtained.
