With unremitting efforts, the strengthen magnesia ceramics we development is crystal clear.

在不懈的努力中，现在我们开发的强化镁质瓷。

Leather bookbindings, pigments for paints and majolica (white-glazed pottery) all came from the East, although the Venetians never succeeded in imitating the perfect ruby glaze of Iznik pottery.

皮面图书装订，绘画颜料和珐琅陶器都是来自于东方，虽然威尼斯人未能成功模仿依兹尼克瓷的完美宝石红釉。

A synthetic model of multi-level production planning and control integration is brought forward, which integrated Master Production Schedule , Material Requirements Planning , Shop Floor Control , order acceptance control, order release control and process control into a whole. Besides, a new method of production management—— Theory of Constraints is introduced into the traditional MRP, and a method to integrate TOC with MRP is put forward. As a result, a system of production planning management for ceramics enterprise is developed. Then several problems of shop planning and control for ceramics enterprise including the modeling of production line, the optimized utilization of kiln, the complement and due-date of products are discussed. A mathematical programming model of equalization production for ceramics production line is set up. An optimized model is put forward, which uses genetic algorithm to solve the sequencing problem of ceramics before the kiln.

以生产计划与控制的集成为目标，提出将一个企业中的主生产计划、物料需求计划、车间作业计划与接受订单控制、投料控制与生产控制集成的多级生产计划与控制的总体模型，将一种新的生产管理方法——约束理论引入传统的MRP中，提出了实现TOC和MRP集成的具体方法；针对陶瓷企业的特点，为重庆兆瓷研制了一套陶瓷企业生产计划管理系统；并对陶瓷企业车间计划与控制中的一些具体问题进行了研究，建立了陶瓷生产线均衡生产的数学规划模型，就窑炉的优化利用、产品配套和交货期问题、陶瓷生产线的能力平衡等问题进行了研究。

Methods 20 human biscuspids scheduled to be extracted for the orthodontic reasons were prepared for porcelain fused to matal crown,of which every 2 teeth were from the same patient and the same jaw.

目的 观察极固宁TM涂布于金属烤瓷全冠活髓基牙牙预备体表面21 d对牙髓组织学形态的影响。

Methods 20 human biscuspids scheduled to be extracted for the orthodontic reasons were prepared for porcelain fused to matal crown,of which every 2 teeth were from the same patient and the same jaw. The teeth were randomly, blindly and selfcontrolly divided into 2 groups.In the control group:the temporary crowns were cemented with zinc oxide cement.In the testing group:Green Or was applied before the temporary crowns were cemented with zinc oxide cement.

要领 选择因正畸治疗必要而打算撤废的20颗前磨牙举办金属烤瓷全冠牙体准备，其中每2颗牙均为同颌同名牙；授与随机、双盲、自身比较计划分为2组：比较组在牙准备体上直接用氧化锌丁喷香酚水门汀粘固且则冠；不雅察看组在牙准备体上涂布极固宁TM后用氧化锌丁喷香酚水门汀粘固且则冠。

选择因正畸治疗需要而计划拔除的20颗前磨牙进行金属烤瓷全冠牙体预备，其中每2颗牙均为同颌同名牙；采用随机、双盲、自身对照设计分为2组：对照组在牙预备体上直接用氧化锌丁香酚水门汀粘固暂时冠；观察组在牙预备体上涂布极固宁TM后用氧化锌丁香酚水门汀粘固暂时冠。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
