The crystal of DPCP-ETSC belongs to the orthorhombic system, space group Pna21, and its lattice parameters are as follows: a=1.1478 (2) nm, b=1.3545 (2) nm, c=1.1994 (2) nm, V=l.8646 (4) nm^3, Z=4, Dc=1.345 g/cm^3,μ=0.194 mm^(-1), F (000)=792, R=0.0345, wR=0.0694. The intermolecular hydrogen bonds led to the formation of chain-like one-dimensional compound along c axis and extended along ab plane to form the wave-like supramolecular structure.

DPCP-ETSC晶体属于正交晶系，Pna21空间群，晶胞参数：a=1.1478(2)nm，b=1.3545(2)nm，c=1.1994(2)nm，V=1.5646(4)nm^3，Z=4，D=1.3459/立方公分，μ=0.194mm^(-1)，F(000)=792，R=0.0345，wR=0.0694，此化合物通过分子间氢键形成沿c轴成链状，沿ab平面成波浪状的超分子结构。

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。

Editorial note: Previous studies on black milk and tea polyphenol absorption were mixed in their findings, but this study tilts the health recommendations back in the direction of drinking one's black tea "black", without milk. This is actually not hard to do if you buy a very nice quality loose leaf black tea, but if you purchase only lower quality "fannings" in tea bags, you will find the black tea to be fairly bitter, especially if it is a stronger brew. For those of you who wonder whether you can drink black tea without milk, I suggest you call Strand Tea at 1-888-718-6358 to buy a small trial amount of their Darjeeling Makaibari Estate biodynamically grown Black tea - it's fragrant and very smooth, one of my favorites, and I hope Jack Strand doesn't sell out of it - tell him Dr. Z sent you.

编者按：以往的研究对黑牛奶和茶多酚吸收混在他们的调查结果，但这种研究倾斜的健康建议，在回方向的喝的红茶中的"黑"，不加牛奶，其实这并不难做到如果你购买了一个非常好的品质松散叶红茶，但如果你只购买低品质" fannings "茶叶袋，你会发现，红茶可算是相当痛苦的，尤其是如果它是一个强大的BREW对于你们这些人不知您是否可以喝红茶加牛奶，我建议你致电钢绞线茶在1-888-718-6358买一个小型审判其数额大吉岭makaibari地产biodynamically成长红茶-它的香味，很顺利的，其中一个我的最爱，我希望千斤顶钢绞线不出售了它-告诉他，叶文z传送给你。
