A |     (ECNS) -- Wang Xiji, one of the pioneers of China's space program, an academician of the Chinese Academy of Sciences, and recipient of the "Two Bombs, One Satellite" Meritorious Service Medal, died in Beijing on Wednesday at the age of 105 after an illness.    The China Academy of Space Technology said his death was a great loss to China's space program, expressing deep condolences and remembrance for the scientist who devoted his entire life to the country's aerospace endeavors.    In November 1958, shortly after the launch of the call that "we should also develop artificial satellites," Wang was transferred to the Shanghai Institute of Mechanical and Electrical Design under the Chinese Academy of Sciences, where he became the technical leader for sounding rockets.        At the beginning of the project, working conditions were extremely rudimentary. The team had no experience, reference materials or experts, and had to start from scratch. With only hand-operated calculating devices available, several team members worked day and night for more than two months to calculate a single flight trajectory.    With no launch site, they used a rice paddy on the outskirts of Shanghai as a makeshift launch pad. They hoisted the rocket onto its launch stand with a winch and pressurized the propellant using a hand pump.    On Feb. 19, 1960, Wang and his team successfully launched China's first sounding rocket, the T-7M, from the rice field. Although the rocket reached an altitude of only 8 kilometers, the launch marked a crucial first step in China's journey into space.    During the subsequent development of the Long March-1 rocket, Wang innovatively integrated technologies from sounding rockets and missiles. He formulated the technical plan for Long March-1, China's first satellite launch vehicle, and led the development of its overall design and prototype. His work laid an important foundation for the successful launch of China's first satellite.    In February 1968, Wang joined the newly established China Academy of Space Technology and continued to devote himself to China's space program.    On April 24, 1970, China successfully launched its first artificial Earth satellite, Dongfanghong-1, into space aboard a Long March-1 rocket, becoming the fifth country in the world to independently launch a satellite into orbit.    On Nov. 26, 1975, China successfully launched its first recoverable satellite. While the nation celebrated the successful launch, Wang hurried to the satellite tracking and control center, knowing that the mission would not be considered a complete success until the satellite returned safely to Earth.    He stayed awake for three days and three nights. Only when he saw the red-and-white parachute appearing in the sky did he finally relax. The successful recovery brought back China's first batch of high-resolution remote-sensing film covering the country, providing basic data for national land surveys, topographic mapping and other applications. China thus became the third country, after the United States and the Soviet Union, to master recoverable satellite technology.    Wang said he felt the main meaning of life lies in participating in the great cause of socialist construction and contributing his share to it. "I understand the cause of the Party and have made up my mind to strive to become a Communist," Wang wrote in his application to join the Communist Party of China.    He remained committed throughout his life to his belief that "one should strive to be a Communist," and honored his lifelong pledge: "I am willing to be a paving stone for space."    (By Gong Weiwei)                    。    

原标题:华为Mate 50的mate是什么意思?时隔两年之后,华为Mate系列又回来了。9月6日,在华为Mate 50系列及全场景新品秋季发布会上,华为正式发布Mate 50系列手机,是全球首款支持北斗卫星消息的大众智能手机。为什么叫“mate”?Mate系列由于它的电池容量大,手机续航能力强,因此它针对的目标消费群体主要是商旅人士。

B | Mate系列可以说是华为目前最高端的手机了。mate在英文中是朋友、伙伴、伴侣。

C | 在男人之间比较常用,比如哥们儿、伙计、老兄等。

D | mate的含义:n. 助手,大副;配偶;同事;配对物例:Nibs and John were first and second mate.尼布斯和约翰是大副和二副。

E | 例:He has found his ideal mate.他已经找到了理想的配偶。

F | vt. 使配对;使一致;结伴 vi. 交配;成配偶;紧密配合例:One day the wretched cat came into my room with a moth in its mouth. I thought it had knocked over the cage but it was still there, surrounded by male hawkmoths who had come for miles to mate.有一天我看到这讨厌的猫嘴里叼着一只蛾子进了我的屋,我以为它把笼子打翻了呢,但是没有,笼子好好的,外面围满了从几英里外赶来交配的雄天蛾。工作中,手机就像是我们的mate 生活中,我们有roommate、soulmate...Mate虽然没有friend的正式,但很容易拉进了人与人之间的距离,而且很有记忆点。

G | P系列的由来了解华为的朋友或许会听说过“华为Ascend系列”,而如今的华为“P”系列正是其分支之一。在其正式上市之后,华为P系列人气不断攀升,致使其独立了出来,形成了如今的华为“P”系列。在此之前,华为“P”系列与华为D、G、Y系列同归于Ascend系列门下。而该系列中的“P”则为“Platinum”单词的缩写,意为“铂金”。看到这里大家则自然知晓,华为“P”系列如今的高端定位级别与其定名则是相辅相成的。nova的意义关于nova的含义,一直谣传:no OPPO、Vivo and Apple,网友热血沸腾,觉得这个名字太霸气了!事实上,华为解释了nova的含义。“nova”在拉丁语中是新星的意思,就这样一颗新星诞生了。相对年轻派、时尚风的“nova”系列在外观设计、拍照和娱乐功能等方面不断跟进时代步伐,很受年轻人消费者群体的喜爱。定位大师特劳特在他的《定位》一书中,是如此描述品牌名字的重要性的:“名字就像钩子,把品牌挂在潜在顾客心智中的产品阶梯上。在定位时代,你能做的唯一重要的营销决策就是给产品起什么名字。”不得不说,华为无论是大局观还是细节都把控得死死的。大家发现了吗,除了系列名,手机公司还特别喜欢给产品加后缀。比如:Pro、SE、Plus、note...英大给大家科普下:Pro :pro是professional的意思,也就是称之为”专业版/顶配版“。专业版拥有拓展的隐含意义,在pro系列中会有很明显的功能增强,带有部分的新科技,如华为P20pro,P30pro。SE 真正意思是“special edition”(特别版)。手机特别版本在价格与配置上都比普通版的要高。外观上也存在差别,特别版外观上更华丽和美观。

H | Plus&Max :plus是英文增强型(一般翻译成+,加),max是最大的缩写。两个都是表示与基本款基本一样,但在某些方面有了增强,是本系列的升级,不过最主要的还是在屏幕和价格上。Note :note原指笔记本电脑。手机note指屏幕比较大的手机,像平板电脑,一般都在5寸以上。说通俗点就是大号版的手机,比如红米note就是红米的大号版本,三星NOTE系列手机都是大屏大号手机。现在你明白了吗?申明:本期内容真的不是打广告!大家都用的什么手机呢?评论区里探讨一下!BEC备考资料,免费领取马上领取点击阅读原文,领取备考资料返回搜狐,查看更多责任编辑:
