In this paper, the properties and concepts of dual systems of the two-dimensional singular Roesser models （2-D SRM） are studied. Two different concepts of the dual systems are proposed for the 2-D SRM. One is derived from the duality defined for two-dimensional singular general models （2-D SGM）-called the S-dual systems; the other one is defined based on 2-D SRM in a traditional sense-called the T-dual systems. It is shown that if a 2-D SRM is jump-mode free or jump-mode reachable, then it can be equivalently transformed into a canonical form of a 2-D SRM, for which the T-duality and the S-duality are equivalent. This will be of some perspective applications in the robust control of 2-D SRM.

Sir Nicholas Harold Lloyd Ridley has revolutionized the practice of ophthalmology by performing the firstintraocular lens （IOL） implantation in 1949. His scientific achievement was acknowledged thirty years later, which led to US Food and Drug Administration approval in 1981. Although the basic principles of IOL implantation have not changed since, many efforts have been invested in perfecting IOL design during the past decades.

I. INTRODUCTIONMetallothioneins(MT) are ubiquitously distributed in animal and plant kingdoms. They are cysteine-rich proteins that specifically bind heavy metal ions, such as cadmium, zinc, mercury and copper. The high expression of the MT gene could be induced by heavy metals in vitro and in vivo. The first transgenic mice obtained by Palmiter et al. in 1982 were introduced with an exogenous growth hormnoe gene
