To optimise the pumps' filtration efficiency, Paulaner Brauerei, the largest brewery in Munich , Germany , replaced a traditional hose pump with a Larox peristaltic pump (LPP 40) to feed kieselguhr to a pressure filter which dewaters the spent kieselguhr before disposal.

为了使泵的过滤效果优化，Paulaner Brauerei，德国慕尼黑最大的酿造厂，用Larox的一款蠕动泵(LPP40)取代以前的软管泵来给压力过滤器（在处理前给用过的硅藻土脱水）输送硅藻土。

This paper uses the Laffer curve model to analyze the function among tax rate, tax revenue and industrial economic developments, and believes that effective industrial tax policies could guide all kinds of resources into industries with competitive advantages to upgrade and optimize the industrial structure to make the economy develop healthy.

本文在用拉弗曲线模型分析了税率与税收收入、产业经济增长之间存在的函数关系之后，认为有效的产业税收政策，可以引导资源要素流向民族地区中具有竞争优势的产业，使产业结构不断优化和升级，进一步促进经济的健康发展。

The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.

其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏，以有方向性的杂交和变异加速和调节搜索，同时杂交和变异作用在不同层面上使搜索在整体上均匀化，通过遗传系统里的并行竞争提高整个群体的生存适应力，从而达到整体优化的目的。

Based on analyzing the weighted coefficient matrix of the reconstruction linear model, the convergence speed of ART is enhanced by optimizing the selection order of projections during iteration. The whole performance of the system has been improved. The 12-electrode capacitance tomgraphy system is mounted in the oil/gas/water loop and it is used to monitor oil/gas two-phase flow upwards through vertical pipelines.

为了减少代数重建算法的时间开销，本文从图像重建线性模型的权系数矩阵出发，通过优化各投影在迭代过程中的选取顺序来改善ART算法的收敛特性，使成像系统仅需增加较小的时间开销就可提高系统的成像质量，从而提高了成像系统的整体性能。
