  This study shows one important effect of preexistent cosmic microwave
background temperature fluctuations on the determination of the Hubble constant
through Sunyaev-Zel'dovich effect of clusters of galaxies, especially when
coupled with the gravitational lensing effect by the same clusters. The effect
results in a broad distribution of the apparent Hubble constant. The
combination of this effect with other systematic effects such as the
Loeb-Refregier Effect seems to provide an explanation for the observationally
derived values of the Hubble constant currently available based on the
Sunyaev-Zel'dovich effect, if the true value of the Hubble constant is 60-80
km/s/Mpc. It thus becomes possible that the values of the Hubble constant
measured by other techniques which generally give a value around 60-80 km/s/Mpc
be reconciled with the SZ effect determined values of the Hubble constant,
where are systematically lower than others and have a broad distribution.
