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。

At each penton, a hole (φ=20〓) can be seen connecting the inside and the outside of the capsid, and there is a hole (φ=12〓) at each hexton and the center of 2-fold axis, so there are 132 holes in total at the surface of CSBV.

The present invention relates to a method for heuristically starting up DC brushless servo electric machine, including the following steps of (1) after powerup of an increment type photoelectric encoder, electrifying a stator winding two by two with identical time interval to generate six-directional stator winding resultant magnetic fields;(2) detecting six different angles rotated by the rotor within identical tiny time interval by the photoelectric encoder;(3) selecting most positive value rotation angle from the six different angles, and determining maximum torque corresponding to the stator winding resultant magnetic field, and implementing servo startup using the maximum torque as constant starting torque;(4) after the zero-point signal of the photoelectric encoder occurring, switching to servo operation with normal constant torsion.

本发明直流无刷伺服电机试探启动方法，采用如下步骤：(1)增量式光电编码器上电后对定子绕组采用相同的时间间隔两两通电，顺序产生六个方向的定子绕组合成磁场；(2)由增量式光电编码器检测出转子在相同的微小时间间隔内分别转过的六个不同的角度；(3)从转子六个不同的角度中选出最大正值的转角，确定相应定子绕组合成磁场对应的最大转矩，并以该最大转矩为恒定启动转矩进行伺服启动；(4)当增量式光电编码器零点信号出现后，切换为正常恒转矩伺服运行。

By the B3LYP calculation of DFT, the difference in changes of energy and charge of ion probe C〓 and C〓 interacting with hBN and graphite respectively and the difference in frontier orbital energy level reveal difference in electroaffinity of hBN and graphite. It could be indicated that hBN only shows weak electropositivity, and will not be able to accept electrons from metal.

根据密度泛函B3LYP方法的计算结果，从六方氮化硼与石墨的前线轨道能级和两者对离子探针的作用能及C〓和C〓的电荷变化不同所表现出的在电亲和性上的差异，揭示了金属难以插入六方氮化硼层间的原因是六方氮化硼仅显弱的电正性，不能接受金属转移来的电子。

The research is it introduce Taiwan to teach from elder, by south and north, Fujian Province, flat Pu; Six piles of elders' church has set up, has organized a lot of characteristic Hakkases in the church, they are stating Christ with the language of Sixian Dialect of Hakka,, are praising God with the song of four counties; Then met the tradition, has run into culture, merge and compose the cultural spirit in the ground together in locality and community, set out together, recall Hugh Ritchie pastor, far to is it come pile of lands say six words of people to go abroad from Britain, spread and say God's country, went through Taiwanese's pyreticosis and passed away, was burying and catching dogs, he has reflected God's decree, prefers burnouting to decaying, has witnessed long and taught and taught burning instead of the grain spirit that is destroyed too.

此篇研究从长老教会传入台湾，由南部而北部，由闽南、平埔而客家，於是六堆的长老教会建立了起来，组织了很有特色的客家教会；以四县话述说著基督，用四县的歌声颂扬著上帝；然后碰到了传统，碰上了文化，再融合於当地与社区共谱在地的文化精神，一起出发。回想李庥牧师，远从英国漂洋过海来到六堆的土地上说六堆人的话语，传讲上帝的国度，经历台湾人的热病而去世，葬在打狗，他回应了上帝的旨意，宁愿烧尽而不愿朽坏；见证了长老教会焚而不毁的精神。
