A | 成都8月21日电(单鹏)第二十九届成都国际汽车展览会(以下简称成都车展)21日在成都开幕。作为成都车展官方活动，2026汽车先锋思享荟21日下午举行。 The same technology that may power the next generation of mobile networks has been shown to increase the growth of brain cells in mice, according to a new study from Xian Jiaotong University in Beijing.,Radio waves in the terahertz frequency can transmit data at speeds up to 1 terabit (or 125 gigabytes) per second, it is a prime candidate for the next generation of mobile cell phone networks if it can be proven safe. By contrast, current 5G networks use millimeter waves that top out at 20 gigabits (2.5 gigabytes) per second.,But there may be another use for terahertz radio waves: treatment of neurological disorders like Alzheimer’s disease, autism, and Parkinson’s disease.,Science & Tech'Vicious Cycle' Between Alzheimer's Dementia and Daytime Napping Found by Scientists17 March, 19:05 GMT,The researchers exposed mice neurons in a petri dish to 100-microwatt pulse radiation, ranging from 0.3 terahertz to 3 terahertz. The result was that the exposed neurons grew at a rate of 150% compared to the control group. The length of connections also doubled in three days. Despite the accelerated growth, the brain cells appeared healthy.,The accelerated brain growth was not permanent; it slowed two days after exposure.,However, a 2009 study by the Russian Academy of Sciences showed that prolonged exposure to strong terahertz radiation had an adverse effect, increasing the temperature of brain cells, disturbing their development and causing dehydration of the cells which reduces their size and causes other damage.,But Li Xiaoli, the lead scientist of the new Beijing study, thinks that the negative effects of terahertz radiation could be avoided by limiting the strength and duration of exposure.,“The safety of terahertz radiation protocol is a top concern,” Li said. And while the health concerns of terahertz radiation remain, it could, Li believes, be used to treat neurological disorders.,“Abnormal neuron development and the resulting abnormal neural network structure can lead to the occurrence of various psychiatric and neurological diseases, such as Alzheimer’s disease, autism and Parkinson’s disease,” the study’s authors said.,The authors believe that a lower dose of terahertz radiation could increase the production and the activity of certain proteins responsible for brain cell growth, namely GluA1, GluN1, and SY-38. The researchers theorize that is because they contain hydrogen bonds that constantly vibrate at a frequency that falls in the terahertz range. The radio waves combine with the proteins and cause them to resonate in a “non-linear manner,” according to Li, which could “affect the shape of the proteins, and therefore the structure and function of neurons.”However, because proteins vary significantly from each other, only certain proteins are affected by the terahertz radiation at low frequencies. Li says more investigation is needed to learn how proteins react to different exposure intensities.,The study backs up another done at the Institute of Brain Science at Xian Jiaotong University that was published in June. That study found that terahertz exposure could make young mice more intelligent. There, scientists exposed mice to 90-milliwatt terahertz radiation for 20 minutes a day for three weeks. They observed that the exposed mice had more brain cells and were quicker at escaping mazes. However, for reasons that remain unclear, the same effect was not observed in older mice.。活动中，中国国际贸易促进委员会汽车行业分会会长、中国国际商会汽车行业商会会长王侠在致辞中谈及当下中国汽车产业发展的“慢变量”。 “过去，我们衡量中国汽车的进步，总习惯用销量说话。其实，销量是一个‘快变量’，受经济环境、政策、周期波动影响甚大。”王侠认为，中国汽车产业的真正竞争力沉淀在“慢变量”之中，中国在全球汽车版图中的引领地位越来越明显。 王侠表示，从技术先进性看，近十年，中国汽车专利公开量持续领跑全球，占比达35.6%，远超美、欧、日等传统汽车强国，在新能源智能化的赛道上，中国汽车的技术实力已实现了整体赶超；中国汽车零部件也突破核心技术“空心化”的难题，一批具备全球竞争力的零部件巨头蓬勃生长。在产品市场表现和技术反向输出上，跨国车企主动选用中方的技术路线、电子电气架构、智驾系统的案例屡见不鲜。 从全球市场表现看，中国汽车的地位和形象正在发生根本变化。今年上半年，比亚迪、吉利、奇瑞三家中国品牌跻身全球车企销量前十，合计占据全球13%的市场份额；同期，中国品牌乘用车在海外市场的整体份额同比提升了2.3个百分点。
B | 在欧洲，中国汽车品牌的新车注册量连续两个月超越日本，仅次于欧洲本土。
C | 在海外消费者心目中，中国汽车品牌形象明显改善。 在合资合作方面，产业政策放开后，跨国车企并没有独自“单飞”，将中国视为全球研发与制造高地，不仅主动采用中方最新技术、更多倚靠中国研发和营销团队，并尝试将中国制造的产品向全球输出，合资车企的战略从“在中国，为中国”升级为“在中国，为全球”。 在规则与生态层面，中国汽车正在成为主要的构建者。
D | “十四五”以来，中国推动组建多个国际标准工作组，牵头制定十余项新能源汽车国际标准及全球首个自动驾驶系统技术法规。在海外市场，从“卖车”到“建厂”，再到通过资本纽带“融入本地产业链”，中国汽车正从输出产品升级为构建国际化产业生态。目前，中国车企在海外已有超100个生产基地，海外产能突破250万辆，与整车协同出海的零部件体系同步覆盖全球主要区域。
E | “技术的赶超、品牌的提升、合作伙伴的信任、标准与生态构建，这些都是‘慢变量’。
F | 它更能深刻描绘中国汽车在全球汽车版图中的真实地位，也是渡过眼下销量和利润下滑困局、推动中国汽车由大到强的根本底气，更是长期向好的确定性力量。”王侠说。
