美媒：076最让人担忧的不是电磁弹射，而是其恐怖的生产速度！_我的网站

A |     What better way to figure out a mystery of the ancients than to try it out yourself? That’s what one sailing aficionado from Israel did when confronted with a puzzle from the Christian Bible.,David Gal, a doctoral student in the Department of Maritime Civilizations at the University of Haifa, says he has figured out why the Christian Apostle Paul sailed from Judea to Rome along the southern coast of Anatolia in 60 CE - a route that, to him, wasn’t the most obvious one, since most winds in the Mediterranean are westerlies and Paul was going west.,That year, Paul was sent to the imperial capital to answer to Jewish authorities for preaching the teachings of Jesus of Nazareth, who claimed to have been the Jewish messiah. Most Jews did not accept Jesus’ teachings, and he was tried and executed by crucifixion for blasphemy and subversion in either 30 or 33 CE.,Paul’s journey is recounted in unusual detail in the New Testament book of Acts. The preacher zigzagged his way across the sea, swinging north of Cyprus before heading to the city of Myra (modern Demre) in southern Anatolia. From there, he went west past Rhodes, to Knidos, then south to the southern coast of Crete and west across the southernmost parts of the Ionian Sea. However, he was shipwrecked in Malta and his journey took much longer than anticipated.,“Until recently, we didn’t understand why the Alexandrian grain ship that Paul joined in southern Anatolia, bound for Rome, chose that particular route,” Gal told Haaretz.,The boat, Ma’agan Mikhael II, is a replica of a ship found in 1985 about 2 meters underneath the seabed off the coast of Kibbutz Ma’agan Mikhael in northern Israel, not far from Caesarea. In ancient times, the city was known as Caesarea Maritima or Caesarea Palestine, named after the Roman emperor Augustus Caesar. The replica boat was finished in 2016 and is just one of two ships in the world that simulates a merchant sailing vessel from Before the Common Era (BCE).,By coincidence, Caesarea also happens to be the port from which Paul left on his trip to Rome.,In part, Gal’s study was based on computer modeling, which combined vast amounts of weather data and conducted 5,479 virtual sailing trips along 224 different possible routes from Caesarea to Rome, for a total of 1.2 million virtual sailing trips. However, that wasn’t enough: Gal also took a crew of 10 volunteer sailors out in the Ma’agan Mikhael II to explore the intangible human element of the journey. With just one sail, the ship moves along at a brisk 3.9 miles per hour.,“Only when we sailed on Ma’agan Mikhael II did we understand the real limitations of the ship and the sailors,” Gal told Haaretz. “We found that in many sections of the coast, the breeze doesn’t support this type of movement.”,“They didn’t sail counter to the prevailing wind, but waited for days with a favorable wind in the opposite direction,” Gal concluded. “We found there were such days in a large meteorological sampling. Until now, scholars didn’t examine that but used low-resolution meteorological averages that erase the variance in the wind.”,Gal said he has taken the ship out more than 80 times, sailing as far as Cyprus, and found that the daily wind patterns, in which breezes can blow westward from the Levantine coast, have remained strong after 3,000 years. By navigating those patterns, ancient sailors could have crept up the coast until they found more favorable winds.,“We have data about its performance in all wind conditions and how various currents affect it, and that enables us to conduct a reliable simulation of sailing. With its help, we acquired insights into the way such a ship is operated; we had a better understanding of how four people can sail from Greece to here and back,” he said.。    年底这几天，中国军工领域接连“放大招”！让军迷们以及国人一阵激动。从076型两栖攻击舰“四川舰”到传闻中的六代机首飞，再到空警-3000曝光，看起来像是技术上的“炫技”，其实更像硬实力的“宣言”。先说“四川舰”，这艘076型两栖攻击舰亮相之后，就把全球海军圈燃炸了。原本大家还认为，美国的“美国”级两栖攻击舰已经够可以了，能搭载F-35B战斗机和“鱼鹰”倾转旋翼机，航母味十足。但是“四川舰”的登场直接改变了游戏规则。最惊艳的亮点就是搭载了电磁弹射系统。要知道，这项技术此前全球只有美国“福特”级航母在用，而且“福特”号的问题多到快成梗了。中国解决了技术难题，还把这套系统直接用在两栖攻击舰上，试问还有谁？有了电磁弹射之后，“四川舰”就可以起飞多种固定翼飞机，包括无人机，战力和作战灵活性直接上了一个台阶。再加上“四川舰”超4万吨的排水量，还有全通飞行甲板，看起来更像是一艘轻型航母。无论是登陆作战，还是执行空中支援任务，甚至是无人机作战，它都可以轻松应对，活脱脱一个“全能选手”。需注意到，比“四川舰”本身更震撼是它的建造速度。从2023年10月开工到2024年12月下水，整整14个月，这个效率放眼全球，直接让外媒哑口无言。关于美国的“福特”级航母，十多年才磨出一艘，问题还一大堆。

B | 中国一艘四万多吨的大舰不到一年半就造出来了，质量还完全在线。西方媒体都直言不讳地说，这种速度让美国感到“极度不安”。毕竟造舰速度是工业体系实力的反映，这才是真正的“杀手锏”。“四川舰”的热度还没散，六代机的首飞传闻又吸引了全球目光。从曝光的图片来看，这款六代机采用了无尾翼设计，隐身性能和气动布局相当激进。最吸引注意的是，它还配备了三台发动机，这种配置大大增强了续航能力和作战半径。

C | 另外，六代机还能携带无人机协同作战。试想一下，主机负责隐身突袭，无人机则在旁边骚扰、侦察甚至直接进攻。这种玩法能把敌人的雷达、预警机、运输机全部瘫痪。对比之下，美国的NGAD六代机项目进展缓慢，造价更是高到离谱，一架要3亿美元。而国的六代机已经进入首飞阶段，性能看起来还不输。这让美军的心里压力只会更大。这也是一种侧面提醒，美国航母编队在南海挑事？周边某些国家做小动作？中国的立场很明确，和平合作我们欢迎，要是搅局闹事会“奉陪到底”。四川舰”14个月下水看似惊艳，但绝不是偶然现象。从055万吨驱逐舰到075型两栖攻击舰，再到今天的076型，中国造舰的能力已经完全处于世界顶级水准。换句话说，这是一场经过几十年厚积薄发的“工业奇迹”。
