With the continuous improvement of people s material living standards . the viewership of television programs and programs loops of a higher quality , the use of the growing popularity of digital microwave transmission . following is a system widely used in digital microwave radio and television transmission equipment 随着人民物质生活水平的不断提高，对电视节目的收视质量及节目套数提出了更高的要求，数字微波传输的使用日趋普及，以下是在广播电视系统广泛应用的数字微波传输设备
This thesis has used and investigated the achievement in serving management of the experts and scholars of the western developed country synthetically , trying to mix the theory of service profit chain and the service quality gap model ( gap model ) and construct the gap model of the service quality inside hotel enterprises . part four : positive research of the gap model of the service quality inside hotel enterprises . though the theory of the parasuraman , this thesis optimized the servqual model and combined the characteristic of hotel enterprises , then proposed hotel enterprise carry on servqual in five model test system : security test and assess system , independence test and assess system , scientific to test and assess system , fairness test and assess system , getting satisfied to test and assess 在parasuraman , zeithaml和berry等人研究的基础上,对其提出的servqual模型进行了优化,结合模型中的各项评价指标和饭店企业的特点,提出了饭店企业进行servqual模型测评的五大测评体系:即安全性测评体系、自主性测评体系、科学性测评体系、公平性测评体系和满意性测评体系,然后选取了湖北h饭店作为研究对象,进行科学地实证研究并在此基础上对饭店企业内部服务质量差距模型进行了延伸性的探索和研究,得到了饭店企业内部服务质量差距的数学模型,并把这套数学模型编写成程序。
Statistically , about five hundred sets of numerical control laser cutters will be required in china during the tenth five - year plan period . besides the universal co2 laser cutters , we also need numerical control laser cutters , such as high - speed and high - precision style , large - scale style for cutting thick iron plate , three - dimensional style and laser cutter robot 据估计， “十五”期间，我国至少需要500多台套数控激光切割机，其中除了通用的co _ 2激光切割机之外，还需要高速、高精度的数控激光切割机，切割厚板的大型数控激光切割机，三维立体数控激光切割机及激光切割机器人等。
