33 killed in Nepal floods, landslides_我的网站

终极一家

一 | 8 月 25 日消息，据外媒 motor1 今天（25 日）报道，保时捷围绕车载音响升级提交了多项专利申请，这次追求的并不是更大的音量，而是更高的效率。

二 | 保时捷称，全新的柏林之声 3D 高端环绕声音响系统，是首套采用氮化镓（GaN）并达到量产条件的车载音响系统。这种半导体材料在手机充电器中更加常见，此前很少与跑车音响联系在一起。氮化镓在电压转换时产生的热量明显少于汽车行业长期使用的硅芯片。

三 | Kathmandu, Oct 12 (UNI) At least 33 people have died in floods and landslides across western Nepal in the past week, local media reports say.
The worst of the monsoon rains hit Karnali province in the north-west, where thousands of residents were evacuated, officials said.
Nepal is nearing the end of its monsoon season, which typically begins in June and ends in October.
At least 110 people have died this year in rain-related disasters, according to the National Emergency Operation Centre.
Hundreds of homes have been damaged in the avalanches and flooding. At least 22 people are still missing across the province and scores more have been injured, the BBC reported.
Rescuers have described difficulties in getting to the mountainous region amid continued rain.
'We have mobilised police officers on the ground. We have arranged a helicopter for air rescue from Surkhet," said one police spokesman, quoted by the Annapurna Post.
"However, unfortunately, due to the weather not improving, progress is not being made as expected."
Most reports of missing people came from the low-lying Kalikot district. Thousands were evacuated from their homes there in the past week amid warnings of intense rain.
In some areas of the province, the Karnali river had risen to over 39ft , Nepal's emergency authorities said.
Several suspension bridges over the river had also been washed away, local media reported.
Government officials have dispatched aid to the region on helicopters.
The UN's humanitarian agencies said they were distributing food and medicine to the worst affected communities in western Nepal.
UNI ING。保时捷首先把这项技术应用在 400W 低音炮功放上，并计划从 2027 年开始用于未来的量产车型。保时捷强调的核心优势是效率，而不是单纯提高音量。

四 | 氮化镓晶体管的开关速度比同类硅晶体管更快，转化为热量而损失的能量也更少。对于跑车来说，这项优势尤其重要，因为重量和散热一直是工程师必须兼顾的两项指标。这套系统并非单纯为了改善音质。保时捷与柏林之声和斯图加特大学鲁棒功率半导体系统研究所共同开发相关技术，项目从 2024 年春季的一台原型功放起步，重点放在提高效率和缩减硬件体积。发热量降低后，功放可以做得更小、更轻。保时捷称，散热器体积可以缩小约 20%，电容、电感等无源元件也能进一步缩小，同时维持原有输出能力。散热器所需的铝材随之减少，由于铝材生产耗能较高，制造环节的资源消耗也可以降低。现有保时捷车型不会因此获得升级。采用氮化镓技术的柏林之声音响系统将用于一款 2027 年推出的未来量产车型，本质上是一项新车硬件设计，而不是能够通过软件推送给现有车辆的功能。
