A | 上海8月26日电(娄瀚锟 谢梦圆)近日，上海首条跨越长江的轨道交通—22号线(市域崇明线)列车陆续运抵上海，线路正式进入车辆交付、全线同步调试验证关键期。 The People’s Liberation Army (PLA) Eastern Theater Command lambasted the US for "collusion and provocations" on 8 July, stressing that its troops are on high alert and are ready to enhance combat preparedness to safeguard China's national sovereignty, security, and peace. It also accused the US of encouraging Taiwan's secessionist sentiment.,"There are three major channels to deliver political signals to Taipei," explained Dr. Chang Ching, a research fellow from the Taiwan-based Society for Strategic Studies and a lead military expert on the People's Liberation Army and regional security in Taiwan. "They are spokespersons of Beijing’s Foreign Ministry, Taiwan Affairs Office and the Defense Ministry. It is relatively unusual to direct a PLA spokesman to deliver such political signals.",Dr. Chang suggests that the PLA's statement appears to be a new psychological operation aimed at the US and Taiwan. The military expert has drawn attention to the fact that "for any sophisticated and well organized military maneuvers, it is always necessary to have proper prior preparation." As such, he suggested that the exercises and the US visit are not causally linked.,"The possibility for the People’s Liberation Army to conduct an improvised military exercise simply reacting to any United States political figure visiting Taiwan is extremely low," the professor argued. "The visit of the US Senator Rick Scott to Taiwan, the premeditated military [exercises] in airspace and waters around Taiwan and the PLA routine press conference just happened on the same day. And a smart PLA spokesman grabbed the chance to exercise his psychological warfare skill and achieve the perception of warfare effects.",China's Military Ready to Prevent Attempts to Achieve ‘Taiwan Independence’17:00 GMT,Washington's Unbalanced China Strategy,The US has been heating up the Taiwan Starits recently. In October 2021, a US special-operations unit and a contingent of Marines were discovered secretly operating in Taiwan for about a year to train military forces. Furthermore, Washington has doubled its unofficial military presence on the island between 31 December 2020 and 30 September 2021, according to the Pentagon's Defense Manpower Data Center. Beijing issued warnings to Washington over the reports.,Washington also upped the ante against China in late February by sending a delegation of former senior defense and security officials to meet Taiwan's president and defense minister, despite Beijing blasting the move as a violation of the China’s sovereignty.,Over the past few months, the Biden administration has likewise ramped up its rhetoric over Taiwan with President Joe Biden even going so far as to repeatedly pledge to "defend" the island from China. Beijing harshly criticized Biden's statements, even though the White House walked the president’s remarks back.,As the Beijing-based daily Global Times commented on the matter, "Biden’s remarks on 'intervening militarily' in the Taiwan question are not a gaffe but signal [the] hollowing out [of Beijing’s] One China policy." In accordance with the One China Policy, Taiwan is part of the People's Republic of China (PRC). However, Washington has long maintained relations with the island, even though it severed official diplomatic ties with Taipei in 1979.,"There are many political commentators and military analysts expecting the worst-case scenario will emerge sooner or later," said Dr. Chang, referring to the possibility of a US-China military standoff over Taiwan. "However, as long as all parties involved in such a circumstance with high uncertainties and tensions are sensible enough, the hope for peaceful resolution of the cross-strait animosities will not totally diminish though many observers will think otherwise.",Biden's 'Strategic Confusion': Why China Won't Fall Into US Traps in Taiwan & Indo-Pacific24 May, 15:08 GMT,The professor believes that as for now, the possibility of any significant Sino-US conflict is quite unlikely. While the differences between Washington and Beijing do exist, "the mutual communication channel and crisis prevention mechanism is also functional," according to the expert.,Dr. Chang went on to claim that the Biden administration's provocative moves with regard to Taiwan could be explained by simmering divisions within the White House.,"Many indications of internal conflicts emerged within his national security and foreign policy team members," he said. "Some key members still keep strong ambition to exercise the salami-slicing tactics on [the] Taiwan issue for acquiring leverage towards Beijing. On the other hand, there are other members who are more willing to seek the possibility for mutual cooperation with their counterparts in Beijing and they will exercise a different set of policies towards Taipei and Beijing accordingly.",As a result, the US administration's strategy remains inconsistent, with Biden’s government being "an orchestra with no competent conductor to coordinate his foreign and security policies.",However, Washington's unbalanced approach comes at the expense of the Taiwanese inhabitants. The present administration's negligence to the peace and stability of the region stems from the fact that "the criteria of supporting Taiwan is to serve the United States national interests, not Taiwan’s welfare," according to the professor.,"Of course, in some cases, there are mutually beneficial solutions and arrangements in US-Taiwan relations," he said. "Nonetheless, US interests are always the concern with higher priority for the leaders in Washington."。目前全线接触网一次性送电成功，热滑试验顺利完成，线路已具备列车上线调试条件，为全线联调联试打下坚实基础。 据了解，22号线共采购40列3编组全自动列车，现已交付14列。其中10列完成车辆调试并移交信号系统，静态调试全部结束，6列正在开展ATO列车自动运行动态测试，全线信号ATO动车测试同步推进。
B | 这条跨江线路配备GoA4最高等级全自动无人驾驶系统，列车最高时速可达120公里，全车采用软硬件双重冗余设计，小故障下可实现无感运行；车厢布局优化提升乘坐体验，依托车地智能联动，故障排查检修效率进一步提高。维保团队实行24小时不间断作业，逐项验证车辆各项性能，保障后续运营安全。 针对超长跨江隧道复杂工况，建设团队多专业协同攻坚。供电系统创新采用双向变流器，保障长距离隧道电压稳定；信号系统结合跨江运行环境优化接口适配，下一步将开展高难度高速无人驾驶功能验证；工务土建板块完成轨道高精度调校，对隧道、人防门、防淹门等设施全面巡检排查，守住行车安全底线。
C | 自长轨贯通后，建设单位统筹推进供电、通信、信号设备安装，投用电力监控、区间泵站、全线CCTV监控系统，落实汛期安全保障，多轮开展全线人工巡道。本次热滑试验完成对轮轨、弓网匹配的完整验证，各系统运行参数全部达标。
D | 下一阶段，各参建单位将继续并行推进调试与各项验收工作，全力冲刺开通目标。线路投用后，将极大便利崇明岛、长兴岛及浦东沿线市民跨江出行，助力上海轨道交通网络化高质量发展。
