在主元素氧化物和微量元素、稀土元素含量上，克雷克特山、鸟角和博尼湖南岸的碧玄岩、碱玄岩成分比较类似，均具有较高的MgO、TiO〓、过渡元素和相容元素，较低的SiO〓、Al〓O〓、K〓O、Na〓O、不相容元素和稀土元素；罗德角和伊万思角安粗岩雷同，它们具有较高的SiO〓、Al〓O〓、Na〓O、K〓O、稀土元素和不相容元素，较低的MgO、TiO〓、过渡元素和相容元素，但五地区火山岩几乎具有一致的Sr、Nd同位素比值，〓Sr/〓Sr＝0.703115-0.703344、〓Nd/〓Nd＝0.512892-0.513076，在Pb同位素比值上，五地区的〓Pb/〓Pb＝18.664-19.913，其中碧玄岩和碱玄岩比安粗岩的比值稍低。

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 element equations are derived in a fixed current element coordinates which are coincident with the current moving element coordinates. The perturbed moving element coordinates and the variation of the element nodal rotation parameters corresponding to the perturbation of element nodal displacements and rotations referred to the current fixed element coordinates is consistently determined using the first order linearization of the way used to determine the current element coordinates and element nodal rotation parameters corresponding to the incremental element nodal displacements and rotations referred to the global coordinates.

本研究在梁元素当前的变形位置上，利用元素节点的座标及断面方位建立一个移动元素座标并决定元素节点的旋转参数，对应於元素节点旋转参数扰动量的广义节点力为一广义力矩，为推导传统力和力矩与该广义力矩的关系，本研究在一个与当前的移动元素座标重合的固定元素座标上，推导出元素节点在当前固定元素座标的扰动位移和扰动旋转与元素节点旋转参数的扰动量的关系。

An incremental-iterative method based on the Newton-Raphson method combined with constant arc length of incremental displacement vector is employed for the solution of nonlinear equilibrium equations. The subspace iterative method is used for the solution of natural frequencies and vibration modes for the free vibration of beam structures.

本研究推导元素的节点惯性力时，先将元素扰动位移表示成当前固定元素座标的扰动位移和旋转之函数，故可直接求得元素的节点惯性力，元素的一致性质量矩阵可由元素节点的惯性力对元素节点的加速度微分求得。

And the westernized women's clothing formed, namely the women's clothing of Shanghai's style.2、 Westernized subject content that the westernization of the modeling element is the women's clothing, and modeling westernization of element clothing structure, clothing modeling form change that westernization brings of craft in fact: The westernization of the element of the surface fabric, on one hand influenced by western artistic style, on one hand textile technology, westernized result of technology of dyeing ; The auxiliary materials element is occidentalized to followthe direct result of western fashion , aesthetic change.3、 Key point that Shanghai women's clothing is westernized that widewesternization is the Republic of China period, occidentalize to make the wholeform of the women's clothing changed into the Western-style S type from thetraditional H type in wide type, the change of such external form is the widecultural transition to narrow clothes decorations culture of clothes decorations infact.4、 In the westernized course of the women's clothing of the Republic of ChinaShanghai, 1920 times rely mainly on the fact that the dress is matched andoccidentalized ; 1930 times rely mainly on occidentalizing in modeling ; And1940 times rely mainly on the fact that the auxiliary materials are occidentalized .

局部西化女装是在保留部分传统女装构成元素的基础上，通过造型元素西化、面料元素西化或辅料元素西化，而形成的西化女装，即海派女装。 2、造型元素的西化是女装西化的主体内容，而造型元素的西化实质上是服装结构、工艺的西化带来的服装造型形态变化；面料元素的西化，一方面是受到西方艺术风格的影响，一方面是纺织技术、染色技术的西化结果；辅料元素西化多是追随西方流行时尚、审美变化的直接结果。 3、廓型的西化是民国时期上海女装西化的关键所在，廓型西化使得女装的整体形态由传统的H型转变为西式的S型，这种外在的形态的改变实质上是宽衣服饰文化向窄衣服饰文化的过渡。 4、民国上海女装的西化过程中，1920年代以服饰搭配西化为主；1930年代以造型西化为主；而1940年代以辅料西化为主。

The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。

It is different from the finite element method which uses the calculus of variation to construct the element-based approximate equilibrium equation. It does consider the equilibriums of forces on the inter-element boundary, which are neglected in the finite element method through the weak formulation.

这种方法跟有限元素法不同，因为有限元素法是采用变分法建立各个元素的近似平衡方程式，这种方法也考虑元素与元素相连接的边界上的力平衡条件，而在有限元素法的推导过程中我们忽略了这种条件。

Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov. Original mantle-normalized distribution pattern of incompatible elements is one kind of rich -in-strongly incompatible elements type with enrich of K and loss of Sr, P, Ti and trace element association makes a feature of siderophile and chalcophile elements. The tectonomagmatic discriminating shows that mantle -derived granitoids in Southern China belong to orogenic granitoids formed in island arc/marginal sea basin system.
