052 Describes and claims a body of polycrystalline dielectric ceramic material having a lead zirconate--lead titanate--lead stannate composition falling within the area A B C E F of the triaxial diagram 1d of the drawings accompanying this specification and containing at least one substitutional additive ingredient selected from the group consisting of elements having respective ionic radii sufficiently close to the ionic radius of one of the elements lead, tin, titanium, zirconium and oxygen to permit of substitution, and a valence state differing from that of said one element by less than three units, the aggregate quantity of additive ingredient amounting to from 0.1 to 5 percent of the replaced ion on an atom basis, each additive ingredient present in said material being in ionic form and substituting for a finite percentage of the ions of a particular one of the elements lead, tin, titanium, zirconium and oxygen with respect to which it conforms with regard to ionic radius and valence state, said additive ingredient replacing a quantity of said elements having in the aggregate an equal number of valence units.

参考译文：第 1012052 号专利说明书介绍一种含有锆酸铅，钛酸铅，锡酸铅的多晶陶瓷介质材料，其组成在说明书附图 ld 三元相图中处于 A B C E F 区域内，该组成至少还含有一种置换添加物，这种添加物从一组离子半径分别接近于铅，锡，钛，锆，氧的元素中选出，以利于互相置换，而与上述一种元素化合价之差应小于三价。该添加物的总量为被置换离子的 0.1%~5%克原子。上述材料中的每种添加物是以离子形式存在的，它以一定的百分数置换铅，锡，钛，锆，氧中的某一元素的离子。添加物在离子半径和价数上必须类似于上述任一元素，并且置换添加物的量与被置换的元素在总体上具有相等的化合价数。本句由两个简单句构成，一个主句，另一个是定语从句。
