Eqrrgtion (25), though representative <strong>of</strong> a rirpllfied mtem, is<br />
still quite qlex. It is <strong>the</strong>refore <strong>of</strong> considerable ralue to attrpt<br />

Equations (24) and (25) are <strong>of</strong> <strong>the</strong> forp<br />

possible to obtain an'appmxbate factorisation <strong>of</strong> <strong>the</strong> donainator In<br />
