1593	因此，该拓扑结构对于研发高性能单相全桥逆变器具有重要参考价值。	Therefore, the topology has an important reference valuefor the research and development of high performance single-phase full-bridge inverter.
1594	空间耦合(spatially coupled)LDPC 码为通信系统提供了一种全新的接近容量限的方式，但在耦合过程中需要额外添加校验节点，因此存在一定的码率损失。	Spatial coupled LDPC (SC-LDPC)code provides an entirely new way of approaching capacity for com-munication systems, however, a rate loss caused by additional check nodes during the coupling process. In order to eliminate rate loss, a coupling method was proposed.
1595	为了消除码率损失，提出了一种新型的耦合方式，首位置变量节点的边展开方式不变，中间位置的边连接到前一个位置的校验节点并依次向后展开，末位置的边与首位置的边成对称分布，	The edges expansion of the variable node in the first position were unchanged, and the edges of the middle position were connected backwards from the previous position check node, then the edges of thelast position were symmetrically distributed with the edges in the first position.
1596	从而得到了一种无需添加额外校验节点，码率无损失的 SC-LDPC 码变体结构。	Therefore, a rate-loss-free SC-LDPC codewas designed without added addition check nodes.
1597	在 AWGN 信道中通过外部信息转移(ex-trinsic information transfer)理论分析及误比特率性能仿真，结果表明:	Extrinsic information transfer (EXIT)theoretical analysis and bit errorrate performance simulation were adopted in the AWGN channel.
1598	相对于 SC-LDPC 码的传统结构，本文提出的 SC-LD-PC 码变体结构在链长较短时不仅能避免码率损失，并且具有更优的阈值和译码性能，在未来通信系统中更具优势。	It is showed the SC-LDPC variant structure is superior to the traditional structure with a shorter coupling chain length, not only can the rate loss be avoided, but also better threshold and decoding performance, it has more advantages in future communication systems.
1599	随着云计算、物联网和人工智能等 IT 技术驱动数字经济产业的繁荣发展，现代企业信息化需求对数据中心存储能力提出了更高的要求和挑战。	With the development of digital economy industry driven by IT technologies such as cloud computing, in-ternet of things and artificial intelligence, modern enterprise information demands put forward higher requirements and chal-lenges for data center storage capacity.
1600	RAID 系统因具备良好的数据存储可靠性和磁盘阵列可扩展性而得到广泛应用。	Due to data storage reliability and redundant arrays of independent disks scalability, RAID system is widely used.
1601	为了满足海量数据对存储容量日益增长的需求，业界普遍采用扩容现有 RAID 系统以应对海量数据的存储问题。	In order to fulfill the requirements of massive data for the increasing storage capacity, the in-dustry generally adopts a method of scaling RAID system to solve the problem of storing massive data.
1602	电子商务、Web 服务和金融等行业对数据的实时访问，使得数据中心必须为用户提供 7* 24 的高质服务响应，然而数据迁移量，负载均衡和扩容开销等因素都会影响扩容的效率，	E-commerce, web service and finance access data on real-time, which make the data center must provide high-quality service response for users with 7* 24, but the factors of data migration, load balane and scaling cost will affect the efficiency of RAID scaling.
