In the traditional embedded system design method , the separation of haxdware and software development result in 1ess efficient architecture a - nd delayed design process . the present design technology cannot satisfy the demand of embedded systems design 在传统的嵌入式系统设计方法中，软硬件设计过程的割裂导致了低质量的设计方案和开发进程的拖延，现有设计方法已经不能满足嵌入式系统发展的需求。
Some people from disadvantaged ethnic minorities living in dublin ' s inner city are being forced to take jobs with low pay and live in poor quality accommodation even though they have high levels of education and good standards of english , according to research to be published today 根据今天即将发布的一项研究，一些住在都柏林市中心来自弱势少数民族群体的居民被迫接受低薪工作，并生活在低质量的房子里，即使他们有着高水平的学历和良好的英语水平。
The main work is as follows : 1 . an error resilient algorithm to collaborate multiple description coding ( mdc ) and error concealment ( ecn ) is presented . the strategy of this method is to reconstruct the low quality image followed by recovering the lost wavelet tree with error concealment method when end - user receives few descriptions 在误码环境下,要保证解码端重构图象的质量,就要综合采用多种抗误码方法,本文对差错复原技术的综合应用进行了研究,具体内容如下: 1 、提出了图象多描述编码与差错隐藏相结合的差错复原算法,在接收端接收到的描述较少时,首先根据接收到的若干描述重构低质量的图象,然后采用差错隐藏方法恢复丢失的子波树。
The aim of applicability assessment for urban land use is to seek potential land for city spread and to exert ascendant environment , so that inferior environment and land can be reconstructed and disposed in the process of urban construction , and that the effect of inferior condition on city spread can be reduced . the aim of this study is also to promote harmonious development of urban spread and environment , and improve rationality between city planning and urban land use so that synthetical benefit of jinan can be actualized 济南市城市扩展适宜性评价是为了寻求城市发展的合理空间，充分挖掘研究区范围内高质量的环境，以便在城建开发过程中对低质量的环境和土地进行控制和必要的工程处理，减小不利条件对城市扩展的影响，最大限度地促进城市扩展与环境协调，促进城市规划和城市用地结构趋于合理，充分发挥城市的综合效益。
But the traditional brick - stone residential structure system now could not fulfill the requirements of the market and the costumers and the theme of " sustainable development " , because of its high investment , high expense , heavy pollution , low productivity , poor function and low quality 而我国传统的砖石住宅结构体系采用的是高投入、高消耗、高污染的落后增长方式与低工效、低功能、低质量的生产局面，已不能满足市场、消费者的要求和建筑"可持续发展"的时代主题。
