Then the concept of Futures,Options,Option Pricing and Geometric Brownian Motion is introduced.

然后介绍了期货、期权、期权定价理论及几何布朗运动等的概念，然后在此基础上给出了随机电价的模型的概念。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

Thus attains demand elasticity coefficient and format of demand function.

探讨了陶瓷材料半导化理论模型及主要工艺参数，提出了弱还原氧缺陷半导化工艺模型，并分别用电价掺杂半导化和弱还原氧缺陷半导化两种工艺制备了BaTiO〓半导化样品，考察了样品颜色与电导的关系，提出了一种简易判断粉体样品半导化的方法。

The electric price of infrared ray equipments is high, making the high cost for the products and low efficiency of drying; The price of boiler and its auxiliaries for the radiating fin drying is high, its repairing fee is large and utilization ratio of fuel is low; Although the drying efficiency of hot wind boiler is high, it has large volume of the equipments and high price and is not suitable for the most enterprises.

采用红外线干燥装置由于电价高，企业生产成本较高，干燥效率低；散热片干燥方式采用的锅炉及其配套设备价格高，维修费用大，燃料利用率低；热风炉虽然干燥效率高，但设备体积大，价格昂贵，大多中小企业不愿使用。

The alkali ions that can balance the electrovalence exist in the network structure at this time.

最后碱离子存在于网络结构中，起平衡电价的作用。

Electrovalence:Valence characterized by the transfer of electrons from atoms of one element to atoms of another during the formation of an ionic bond between the atoms.

电价：在原子间形成离子键的过程中，由电子从一种元素的原子转移到另一种元素的原子所表示的价。

To the next century, a 20's, the solar energy electricity generation cost has the possibility to reduce to the level which competes with the conventional electrovalence, widespread large-scale use solar energy and the renewable energy new times - solar energy time is approaching.

到下世纪的一、二十年代，太阳能发电成本有可能降低到与常规电价相竞争的水平，一个广泛的大规模的利用太阳能和可再生能源的新时代－太阳能时代正在来临。

Because both ions in A and B sites of these compounds can be substituted by other ions with different electrovalence and radius in a wide range, their dielectric property is adjustable and can be optimized in a large scale. This implies that new type MWDC with advanced dielectric property may be exploited from these compounds and widely used.

该类化合物由于A、B位均可能被电价与半径不同的阳离子在较宽的范围内取代，所以其介电性质有较大范围的调节与优化的可能性，因此从该类化合物中极有可能开发出具有广泛应用前景的新型高性能微波介质陶瓷材料。
