对具有单位元的模格,本文给出了两种更为简洁的等价条件,并根据模格所满足的幂等律、交换律、结合律、吸收律和模律,证明了有1模格的各种定义之间的等价性。
For modular lattices with unit element, We give another two much simpler equivalent definitions. According to the idemptent law, commutative law,associative law,absorptive law and modular law of modular lattices, We prove the equivalency among the various definitions of modular lattics with unit element.
