The paper defines differentiation operator on H(B)by radial derivative，then it studies the boundedness and compactness of products of multiplication，composition and differentiation between weighted Bergman-Nevanlinna and Blochtype spaces on the unit ball.

1 Introduction

Let D be the open unit disk in the complex plane.Let B={z∈Cn：|z|＜1}be the unit ball of Cn，and S=?B its boundary.We will denote by dv the normalized Lebesgue measure on B.

2 MψCφR and RMψCφ

The following criterion for compactness is a useful tool to us and it follows from standard arguments，for example，to those outlined in Proposition 3.11 of[3].
