查询词典 simultaneous equation

We extend Frankel (1986) and Lai、Hu and Wang (1996) models, where using target zone policy and simultaneous stochastic differential equation methods, to investigate whether the honeymoon effect proposed by Krugman (1991) is present when the government adopts a target zone policy on agricultural prices.

我们将延伸Frankel(1986)及Lai、Hu与Wang(1996)分析农产品市场的概，配合目标区政策及随机微分方程之方法，探讨当农产品及非农产品价格皆可瞬时调整时；政府宣告目标区政策，民众的预期将如何影响农产品价格及其他经济变之稳定性。

It consists of introduction, estimation and application of line shape model of the single equation and establishment and analysis of group's model of the simultaneous equations.

(1) In the sorption kinetics experiment, Cu2+ sorptions by Ceratophyllum demersum, Myriophyllum triphyllum and Hydrilla verticillata respectively, all reached balance within 35mins, all of the test results of sorption kinetics recommended the pseudo second-order equation and indicated that this kind of sorption was a complicated process of simultaneous actions of many reactions. The test results of thermodynamic sorption fitted with Langmuir model better than Freundlich model, and the maximum sorption quantites were 13.12, 20.12, 7.79mg/g, respectively,In the desorption test, the desorption rates of each plants were all below 1%, indicating strong sorption-holding action of these submersed mcrophytes on Cu2+.

通过上述研究，得到以下结论： 1、狐尾藻、金鱼藻、黑藻在对铜离子的吸附动力学实验中，均在35min内达到吸附平衡，分别用一级动力学方程和伪二级动力学方程拟合，结果均为用伪二级动力学方程拟合效果较好，表明该吸附为多种反应同时作用的复杂过程；在热力学实验中，三种植物的吸附曲线都能较好的用Langmuir曲线拟合，其拟合最大吸附量分别为13.12、20.12、7.79 mg/g；在解吸实验中，三种植物的解吸率都较低，说明对铜离子都有较好的吸持能力。

Three displacement functions w,Gand ψare introduced in this paper tosimplify motion equations of elasticity problenis in spherically isotropic media to an indepen-dent partial differential equation concerning one displacement function ψand simultaneous equations concerning two other displacement functions w and G.

本文引入三个位移函数，将球面各向同性弹性力学运动方程，简化为关于ψ的二阶偏微分方程，和关于W和G的联立方程。在静力学问题中，联立方程可进一步简化，w和G可用另一位移函数F表示，而F满足一个四阶偏微分方程。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
