摘要：

The existence and boundednesss of global solutions in one dimension space of a chemotaxissystem with two sensitive coefficients are investigated. Applying Amann theory, the local existence of solutionsof the system is obtained. Furthermore, by using analytic semigroup theory, energy methods and the detailedpriori estimates of solutions, it's proved that the existence and boundednesss of global solutions in one dimensionspace of the system.
