The main purpose of this article is to apply the newly developed Parity Bounds model and then compare it with Ravallion model in the market integration research of Taipei and Taichung aquaculture markets. We choose 11 types of fishes including Japanese sea perch, big head carp, milk fish, grass carp, common carp, curcian carp, white mouth croaker, Japanese butterfish, black pomfret, white pomfret, and gold threadfin.

本研究主要在应用新近发展的等值临界模型对台北、台中两地鱼市场中，都有进行交易之七星鲈、大头鲢、草鱼、虱目鱼、鲤鱼、鲫鱼、白口、肉鱼、黑鲳、白鲳、金线等十一种鱼种进行市场整合检定，并与另一种市场整合检定－Ravallion模型比较，希望藉此二种不同方法来了解台北、台中两地鱼市场间是否符合单一价格法则所隐含之市场整合的情形。

The obtained results show that the extraction time of isosurfaces can be reduced by a factor of four.

试验结果表明，该算法比基于三角网格的等值面抽取时间缩短了约1/4。

It simulates the circuit breaker with a zero impedance branch, and adopts the linear network characteristic and theory, variable structure and variable parameter analyses to transfer the short-circuit current flow in the bus-bar equality into each side of circuit breaker, and deduces the sequence component model and algorithm for calculating the short-circuit current of circuit breaker when the short-circuit fault occu...

该方法将断路器作为一条阻抗为零的支路来模拟，运用线性网络特性、定理及变结构与变参数的分析方法，将母线上短路时的短路电流等值转移到断路器两侧，导出了相当于在断路器两侧分别发生短路故障时，流过断路器的短路电流的序分量模型和算法。

The results show that in subsynchronous frequencies range the transmission line compensated by the SSSC causes a resonant impedance effect similar to that caused by the fixed capacitors. But the value of the capacitive reactance exhibited by SSSC is smaller than that of the fixed capacitors and the additional resistance component is exhibited by SSSC.

研究表明：次同步频率下串有SSSC支路的阻抗特性与串有等值电容支路的阻抗特性相似，但SSSC所呈现的容抗小于固定电容的容抗，且SSSC还呈现较大的电阻分量。

The course contains four sections as follows: mathematical logic (including basic concepts of propositional logic and predicate logic, propositional calculuses and inference theories), set theory (including set algebras, relations, functions and cardinal numbers), algebraic structure (including algebraic systems, semigroups and groups, rings and fields, lattices and Boolean algebras), graph theory (including basic concepts of graph, Euler graphs and Hamiltonian graphs, trees, planar graphs and coloring graphs, some special vertex subsets and edge subsets).

本课程包含四部分内容：数理逻辑（包含命题逻辑与一阶逻辑的基本概念、等值演算以及推理理论），集合论（包含集合代数、二元关系、函数和基数），代数结构（包含代数系统、半群与群、环与域、格与布尔代数），图论（包含图的基本概念、欧拉图与哈密顿图、树、平面图及图的着色、图的某些特殊的顶点子集与边子集）。

First, the state～space equation of the circular inverted pend ulum system was established based on the Lagrange Equation. On the base of that, the circular inverted pendulum was swung up by the energy control strategy, and the controller of the system was designed by the pole placement of the optimal control theory. Second, in order to realize the observation for the unknown vari ables, stable state observers were designed based on the equivalent principle of sliding mode variable structure.

该方案在采用 Lagrange 函数建立状态空间方程的基础上，利用能量控制策略实现自动起摆；采用最优控制理论中的极点配置法设计倒立摆系统的控制器；同时利用滑模变结构的等值原理设计观测器，实现对系统未知状态变量的观测。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
