You have been wisely admonished to "accustom yourselves to think and speak of the Union as of the palladium of your political safety and prosperity, watching for its preservation with jealous anxiety, discountenancing whatever may suggest even a suspicion that it can in any event be abandoned, and indignantly frowning upon the first dawning of any attempt to alienate any portion of our country from the rest or to enfeeble the sacred ties which now link together the various parts."

你们曾被理智地告诫过："你们要习惯于像对待护佑你们政治上的安全与繁荣的守护神那样想到它或谈论它；要小心翼翼、无微不至地保护它：要驳斥一切抛弃它的想法，即使对它抱有丝毫怀疑亦不允许；要义正词严地反对刚冒头的、一切可能使我国的任何部分与其他部分疏远并削弱连接全国各地的神圣纽带的种种企图。"

But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth; as this is the point in your political fortress against which the batteries of internal and external enemies will be most constantly and actively (though often covertly and insidiously) directed, it is of infinite moment that you should properly estimate the immense value of your national union to your collective and individual happiness; that you should cherish a cordial, habitual, and immovable attachment to it; accustoming yourselves to think and speak of it as of the palladium of your political safety and prosperity; watching for its preservation with jealous anxiety; discountenancing whatever may suggest even a suspicion that it can in any event be abandoned; and indignantly frowning upon the first dawning of every attempt to alienate any portion of our country from the rest, or to enfeeble the sacred ties which now link together the various parts.

但是，正如人们很容易预见的是，从不同的原因和从不同的四分之三，但将采取的痛苦，许多技巧来削弱你的头脑的信念这个真理；因为这是指向您的政治堡垒，用以电池内部和外部的敌人将是最经常，积极导演，这是无限的时刻，你应该适当估计的巨大价值的国家联盟的集体和个人的幸福，你应该珍惜了亲切，习惯，和不动产查封的情况； accustoming自己去思考和谈论它的钯的政治安全和繁荣；看其保存嫉妒焦虑； discountenancing任何可能暗示甚至怀疑，它可以在任何情况下，被遗弃；和愤怒时皱着眉头的第一个到来的每一个企图疏远的任何部分，我国从其他国家，或enfeeble神圣的关系联系在一起，现在的各个部分。

You have been wisely admonished to "accustom yourselves to think and speak of the Union as of the palladium of your political safety and prosperity, watching for its preservation with Jealous anxiety, discountenancing whatever may suggest even a suspicion that it can in any event be abandoned, and indignantly frowning upon the first dawning of any attempt to alienate any portion of our country from the rest or to enfeeble the sacred ties which now link together the various parts."

But as it is easy to foresee that from different causes and from different quarters much pains will be taken, many artifices employed, to weaken in your minds the conviction of this truth, as this is the point in your political fortress against which the batteries of internal and external enemies will be most constantly and actively (though often covertly and insidiously) directed, it is of infinite moment that you should properly estimate the immense value of your national union to your collective and individual happiness; that you should cherish a cordial, habitual, and immovable attachment to it; accustoming yourselves to think and speak of it as of the palladium of your political safety and prosperity; watching for its preservation with jealous anxiety; discountenancing whatever may suggest even a suspicion that it can in any event be abandoned, and indignantly frowning upon the first dawning of every attempt to alienate any portion of our country from the rest or to enfeeble the sacred ties which now link together the various parts.

然而，不难预见，会有某些力量试图削弱你们心里对这个真理的信念，这些力量起因不一，来源各异，但均煞费苦心，千方百计地産生作用。其所以如此，是因爲统一是你们政治堡垒中的一个攻击重点，内外敌人的炮火，会不断加紧(虽然常是隐蔽地和阴险地)攻击。因此，当前最重要的是你们应当正确估量民族团结对于你们集体和个人幸福的巨大价值。对于它你们应当怀有诚挚的、一贯的和坚定不移的忠诚；你们在思想上和言谈中应习惯于把它当作政治安定和繁荣的保护神，你们要小心翼翼地维护它。如果有人提到这种信念在某种情况下可以拋弃，即使那只是猜想，也不应当表示支持，如果有人企图使我国的一部分脱离其余部分，或想削弱现在联系各部份的神圣纽带，只要他们一提出来，你们就应当予以怒斥。

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族，全部是固体金属，它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素，它们的外围两层的电子均是5d16s2，而外围第三层的f轨道电子却从零增加到14个，所以外围电子结构为4f0－145d16s2，而使这些元素氧化数均为＋3，化学性质极为接近，提炼时很难分开，它们的矿石又大多是多种元素混在一起的，更增加提纯难度，它们的原子序数为57－71，核内质子数逐个增加，因而对核外电子引力也不断增强，使原子半径随原子序数Z增加而减小，这就使镧系元素收缩、离子半径也缩小，这也使得Zr和Hf，Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似，以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似，因而称这六个元素为铂系元素。

The catalytic activities of some coordination polymers in synthesis of DPC from oxidative carbonylation of phenol were investigated. Palladium complex Pd(C_2O_4)·0.5(C_4H_8N_2) has better catalytic activity in the typical reaction condition, it was synthesized with PdCl_2, oxalic acid and piperazine hexahydrate by solvothermal method under low temperature and characterized by IR, EA and TG.
