Based on translational symmetry of crystal structure, the paper makes an analysis of translational operator eigenvalue equation-Bloch Theorem, electronic Hamiltonian Operator eigenvalue function in crystal-Bloch function and crystal band structure, and illustrates the formation of crystal structure of energy spectrum resulted from features of crystal structure.

The stability of vertical Bloch lines(VBLs)in the second kind of dumbbell domain(IID)walls in LPE garnet bubble films subjected to an in-plane field at different temperature is studied experimentally.

The influence of the magnetostatic interaction between vertical Bloch lines (VBLs) on the stability of hard domains in garnet bubble films subjected to a magnetostatic bias field is investigated.

The ultra-high-density Bloch line memory (BLM) uses negative vertical-Bloch-line (VBL) pairs in the walls of hard domains as information carriers.

Thought Means Surpass:Ernst Bloch s Innovation on Tradition of Marxism;

Das Prinzip Hoffnung is one of the most important works of Ernst Bloch, a famous German neo-Marxist philosopher.

With close reading of Das Prinzip Hoffnung,which is the representative work of German neo-Marxism philosopher Ernst Bloch,this essay analyzes the modern humanist foundation of Bloch s concept of hope,and his complicated relation to the philosophy of Heidegger in particular.
