Wang Xiji, pioneer of China's space program, dies at 105_我的网站

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)                    。    　　美国财政部本周三宣布将长期国债的回购规模扩大一倍。随后，美国财长贝森特暗示，可能会进一步扩大回购规模。这一决定在周三有效压低了美国国债的收益率水平，但在短短两天内几乎失效。
　　周五，30年期美国国债收益率上涨超过2个基点，接近5.28%，逐渐回升至本周早些时候令市场恐慌的5.3%水平；而10年期国债收益率上涨近3个基点，超过4.73%。　　债券收益率连续第二天走高，而美股市场几乎没有乐观反应，这是美国财政部干预努力失败的最新迹象。　　法国巴黎银行策略师Guneet Dhingra团队在一份报告中写道，美国财政部的这些措施难以抵消美联储信誉下降或加息预期上升的影响。　　螳臂当车　　债券市场观察人士一直对美国财政部通过增加长期债券购买来降低收益率的计划持怀疑态度。分析人士强调，美债收益率仍在攀升，因为仅靠财政部无法解决核心问题，即美国政府收不抵支。　　此外，包括通胀担忧、美联储沟通方式的变化以及企业债券发行热潮在内的诸多美财政部无法控制的因素，都导致了收益率的上升。　　Creative Planning首席市场策略师Charlie Bilello表示，美国财政部称之为“债券回购”，但实际上并没有减少债务，他们回购旧债务的同时发行了更多新债券，这只是债务重组。　　威尔明顿信托高级债券投资组合经理Wil Stith则指出，美联储和美国财政部基本上是朝着相反的方向努力，他认为更好的办法是让美联储以比以往更大的幅度调整利率，因为该机构拥有更大的政策空间。　　Evercore ISI分析师Krishna Guha也认为，如果美国政府能够通过减少赤字来从根本上改变经济状况，那将是一个颠覆性的改变，但他团队和其他专家都对此持怀疑态度。　　本周，美国国债突破40万亿美元大关，自2008年以来增长了四倍。联邦预算赤字约占国内生产总值的6%，这是美国历史上罕见的极高比例，只有在战争时期或经济严重衰退时才会出现。（文章来源：财联社）。
