Composition of both spermatophyte and pteridophyte flora of a relict Alsophila spinulosa community in Wutongqiao Nature Reserve of Leshan region was discussed. It shows the proportion of Tropic and Cathaysia elements in both spermatophyte flora and pteridophyte flora was almost 2/3 of the total at the genus level, and even more at the family level. There was a distinct ancient endemism phenomenon in spermatophyte flora, owning to being 8 relict and remnant endemism genera in the total of 9. Furthermore, the proportion of Tropic and Cathaysia elements both at family and genus level in the pteridophyte flora were much greater.

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 elements of family are too many,too many,but nothing we have, except Love....

和家庭有关的因素太多太多，我们什么都没有，除了爱。。

To realize the modern conversion of traditional filial piety and to promote the harmony of modern family are the elements of building a harmonious socialist society.

The series of Memory Phonograph—A Chronicle Collage of Old Family Pictures and Images uses the images and genealogy on the family album as elements of creativity, studies life cycle of human beings and the pursue of values of life. By means of tracing back to the root of the family and going all the way down the reflections of self existence, the creator attains self-discovery in life and finds therapy through art.

记忆留声机—家族老照片图像拼贴日记」系列，藉由家族相簿上的图像以及留下的族谱，作为创作的元素，探讨人类生命物体的周期，对生命价值的探求；上推家族根源的追寻，下至个人自我存在的省思，也是创作者自身对生命的探索与治疗。

Geographical element analysis of' both family and genera revealed that temperate elements took dominant position, and tropic elements accounted for largish proportion.

科和属的地理成分分析表明，研究区植物区系以温带成分为主，热带区系成分也占相当大的比重。

Although clad diamond prevent iron family elements from eroding diamond and improve the strength between matrix and diamond, there still are many problems in applying Fe-base formulae. After the adding amount of reinforced elements is determined, the effect of the basic elements of matrix on its comprehensive performance is studied. The results show that while wc content is 15%. Fe/Ni 1: 1, 663-Cu etc 50%, Sintering temperature 920℃, temperature kept time 1. 5 mintues, matrix comprehensive preformance is best.

尽管金刚石表面镀膜隔绝了铁族元素对金刚石的侵蚀和提高了胎体对金刚石的粘结强度，但以Fe代Co还存在胎体的综合机械性能等问题，本文试着从材料学的强化理论出发确定了微量元素的添加量之后，用正交试验设计方法研究了胎体的基本组元WC、Fe/Ni、663—Cu的加入量及烧结工艺对胎体综合机械性能的影响，得出在WC15%，Fe/Ni1：1，663—Cu等其它为50%，烧结温度920℃，保温时间为1.5分时胎体的综合机械性能最优。
