中化新网讯 DNA因其海量存储潜力被视为下一代存储介质的有力竞争者，然而，高错误率的合成技术 是阻碍其实际应用的瓶颈。近日，天津大学应用数学中心与合成生物学国家重点实验室吴华明教授团队 在国际期刊《自然·通讯》上发表了题为《DNA StairLoop:实现DNA数据存储中高保真数据恢复和强大 的错误纠正》的研究成果，有望加速推动DNA数据存储从实验室走向产业化应用。 随着数据存储需求进入"泽字节时代"(1泽字节约等于1万亿GB)，DNA因其环境友好、稳定性高和存储 密度大等特点，被视为极具潜力的存储介质之一。然而，DNA数据存储的实际应用仍面临合成过程中 的技术瓶颈，尤其是在采用高扩展性、低成本的合成方法(如电化学合成)时，往往伴随较高的核苷酸错 误率与合成不均匀性问题，严重影响数据读写的可靠性。 为应对这一挑战，吴华明团队提出了一种名为StairLoop的DNA存储框架，旨在提升DNA存储系统在高 错误率合成环境下的数据恢复性能。该研究通过设计阶梯式交织结构与迭代式软判决解码机制，在不依 赖复杂多序列比对的前提下，实现了对插入、删除及替换等典型合成错误的有效校正。该方案还具备并 行解码能力，有助于提升大规模 ...

重整装置的催化剂再生效果直接关系到产品质量及收率，而再生烟气微量氧分析仪是保证催化剂再生效 果的关键仪表。自8月以来，广东石化再生烟气微量氧分析仪数值波动较大，影响催化剂再生效果，导 致产品收率不达标。 "从这20天的运行数据来看，重整装置氧含量在0.63%至0.65%之间稳定运行，与工艺工况相符，表明这 次在线氧表改造成功了!"10月9日，广东石化炼油四部工艺副经理宁晓威在中心控制室高兴地说。 对此，炼油四部第一时间联系专利商工程师到现场进行分析诊断，最后确认为传感器老化导致仪表数值 波动，需进行更换。"按照以往经验，更换管道内的传感器需要停工降温降压，会直接影响全年生产任 务。而如果在线拆卸更换，作业人员则要面临风险。"专利商UOP工程师说道。 面对"不停机维修"这一挑战，技术人员广泛研究，最终从其他"抽取式"在线仪表中找到了创新破题的方 向：将传感器从管道内部移至外部。为此，技术人员专门制作了与传感器配套的烟气流通测量池，将旧 仪表的"标定管"作为新表的"采样管"，将烟气样品引至流通池内，实现"外部"测量目的。 为保证传感器及采样管路不被腐蚀，技术人员还就地取材，利用现场250℃的高温烟气管线作为"天 ...
