Abstract

We show that the quark mixing matrix can be parametrized in exactly unitary forms with the imaginary parts present only at the order of

10^{- 3}

. With

s_{x} = s_{1}

and

s_{y}

well determined, measurements of

ε^{'}

or other

CP

-nonconservation effects can determine

s_{z} s_{φ}

. Then after

| V_{ub} | ≃ s_{z}

is measured,

s_{φ}

is known. We also give a simple expression for the

CP

asymmetry in the

B^{0} - B^{0}

mixing.
