“带电赶考”成功 杭州地铁9号线二期顺利完成全线热滑试验_我的网站

A |     近日，杭州地铁四期工程建设又迎来关键性节点——昨天，记者从杭州地铁获悉，9号线二期工程全线接触网热滑试验顺利完成。

B | 这标志着项目已正式具备列车上线运行条件，为后续的联调联试及开通运营奠定了坚实基础。

C | 杭州地铁9号线二期工程位于临平区，南起龙安站（不含），北至塘栖站，全长10千米，主要沿荷禹路、康泰路、港北路、绿荫街敷设，全线共设车站7座，无换乘站。    (ECNS) -- Researchers at The University of Hong Kong (HKU) have developed a minimalist analogue content-addressable memory (CAM) chip that performs complex searches directly where data are stored, the university said Tuesday.    When tasked with calculating the analogue Hamming distance for machine learning classification, the new analogue CAM performed the task approximately 108 (100 million) times faster than a standard CPU, scoring exceptionally high accuracy across multiple datasets, according to the university.    The chip is designed to reduce the slow and energy-intensive transfer of data between memory and processors, known as the “von Neumann bottleneck.” Its architecture can compare incoming search data with all stored data simultaneously in a single step.    Led by professor Li Can from the Department of Electrical and Computer Engineering of the Faculty of Engineering and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC), the team built each analogue CAM cell with just two transistors, compared with up to 16 in a conventional digital CAM cell. The design reduces chip area and allows continuous analogue signals to be processed directly.    Li said the team is exploring how the technology could support search mechanisms in large AI models. The findings were published in Nature Nanotechnology.    (By Intern Yang Hongran, Zhang Dongfang)                    。可能有市民朋友会好奇，“热滑”究竟意味着什么？简单来说，它是供电系统建成后的关键核验工序，就像给新线路做一次“带电大考”——通过接触网带电行车，全方位校验接触网安装精度、弓网受流匹配性、供电系统运行稳定性，以及轨道、车辆、供电多系统协同适配。这次9号线二期工程全线热滑试验顺利完成，列车全程运行平稳，弓网受流状态优良，各项技术指标全部达标。

D | 据地铁相关工作人员介绍，下一步，9号线二期将全面启动多专业联调联试，有序推进通信、信号、综合监控等系统调试，高质量、高标准、高效率完成剩余建设任务，确保线路按期开通运营。
