摘  要：

In this paper, we verify the $L^2$-boundedness for the

jump functions and variations of Calder\'on-Zygmund

singular integral operators. This result should be the

first general criteria for the variational inequalities 

for kernels not necessarily of convolution type. The

$L^2$-boundedness assumption that we verified here is

also the starting point of the related results on the

(sharp) weighted norm inequalities appeared in many

recent papers.
