英文摘要：

In the study of the regularity criteria for the weak solutions of the three- dimensional micropolar fluid equations. A new logarithmieal regularity criterion in Multiplier space for the velocity fields is derived which improves the previous results. The methods are based on the Multiplier space technique and energy methods.
