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。

Temporarily known as ununseptium, because it has 117 protons in its nucleus, it was made at the Joint Institute for Nuclear Research in Dubna by smashing calcium ions into berkelium atoms.

我们暂且称之为117号元素，因为在它的原子核内有117个质子。它是由位于杜布纳的联合核研究所通过轰击钙离子而得到的。

It is difficult to study element 104 because only a few atoms of this substance can be isolated at one time.

对104 号元素进行研究很困难，因为一次只能分离出这种物质的几个原子。

Aluminum is said to be the thirteenth element in the periodic table.

铝是周期表上的第13号元素。

Aluminium is said to be the thirteenth element in the periodic table.

As for updating the periodic table, element 118 would slot in just below radon in the column that contains inert gases.

至于元素周期表的升级，118号元素的位置就在氡列那些气体元素之后。

Promethium is number 61 in the periodic table of elements and finds itself most useful in nuclear reactors as an alpha emitter.

钷是元素周期表中第61号元素，在原子核反应堆中作为阿尔法放射源。

The boundary limit of the periodic system is also one of the transuranium s.

作者认为超铀元素存在的界限大体在Z=110-125号元素，而Z=114-120号元素将更有可能。

The spontaneous fission is primary factor restricting numbers of transuranium elements .

超铀元素的存在受到诸多因素的限制，而自发裂变是限制超铀元素数目的最主要因素，从自发裂变限制方面分析，超铀元素的存在界限大体在Z＝120号元素以内。

The evidence comes in the form of specific isotopes of elements 116, 114 and 112, which are created when element 118 decays.

证据来自第 116、114 和 112 号元素的特定同位素，它们是在第 118 号元素衰变时被创造出来的。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
