Japanese experts believe that North Korean missile technology steadily improved but not yet fully gr soulseek

The US and Japan experts believe that North Korea’s missile technology has steadily improved, but still not fully grasp the data map: North Korea’s rocket launching site. (picture from the network) Reference News Network reported on February 12th   the foreign media reports, the commander of the U.S. Army space and missile defense command said on the 10, although the satellite launch North Korea recently didn’t seem to be able to ground transmission signal, but the rocket payload reached two times the DPRK launched last time, really worry. According to the Reuters reported on February 10th, David · a man in the Capitol Hill conference organization in the United States on the Hudson said: "look at the last launch and payload into orbit at that time, I think only the weight increase is a key factor." He said: "I don’t think the satellite can transmit the signal successfully, but it does reflect the ability of North Korea to try to strengthen the missile technology."." This payload was almost two times as much as the North Korean satellite launched in 2012, Mann said. He didn’t give the exact figure of the payload, but South Korean officials thought it was 200 kilograms. According to Japan’s "Yomiuri Shimbun" reported on the 2 11 7, North Korea launched the long-range ballistic missile, will be equipped with firing to orbit. Although North Korea’s reality is shrouded in a veil, scientists have found that Korean technology is very high-end after analyzing data and pictures. "Korea’s technological strength has steadily improved." After reading the DPRK missile launch screen, Japan’s former Defense Department of the Ministry of Technology Research Institute of the third Institute of long-term protection Tatsunami Nosuke made the above judgment. The orbit of the launch object is close to the special orbit of the earth observation satellite, so it is necessary to fine tune the direction of the flight when the object is put into the orbit. "It can be said that North Korea has mastered the more difficult part of flight control technology," said Akiba Jiro, an honorary professor of the Institute of space science, who has been working on rocket development for many years." The time of the one or two missile falling before it was reduced by 3 to 6 minutes compared with the last time, and the time of firing to the same height can be shortened. "It means that North Korea has been able to burn a lot of fuel in a short time," said Sawaoka Aki, President of the University of Datong, who is familiar with the theory of cosmic engineering. The propulsive force should be about 20% higher than the previous one." Reported, but North Korea will carry things into orbit around the earth, did not let it fall. Therefore, it can be concluded that North Korea has not yet mastered the long-range ballistic missile technology. One of the reasons is that it is very difficult to get the missile back into the atmosphere from space again. Re entering the atmosphere needs to withstand 1000 degrees of high temperature, so the need for high-end heat resistant technology. 美日专家认为朝鲜导弹技术稳步提高但仍未完全掌握 资料图: 朝鲜的火箭发射场。(图片源于网络)   参考消息网2月12日报道 外媒称,美国陆军空间和导弹防御司令部司令10日表示,虽然朝鲜近日发射的那颗卫星似乎没能向地面传输信号,但运载火箭的有效载荷达到了朝鲜上次发射的两倍,着实令人担忧。   据路透社2月10日报道,戴维·曼中将在美国哈得孙研究所组织的一场国会山研讨会上说:“看看上次的发射以及当时送入轨道的有效载荷,我觉得仅仅重量上的增幅就是一个关键要素。”   他说:“我认为卫星没能成功传输信号,但它确实反映了朝鲜在导弹技术方面试图加强的一种能力。”   曼表示,这次的有效载荷几乎是2012年朝鲜发射卫星时的两倍。他没有给出这次有效载荷的具体数字,但有韩国官员认为是200公斤。   另据日本《读卖新闻》2月11日报道,朝鲜7日发射了事实上的远程弹道导弹,将搭载物发射至绕地轨道。尽管朝鲜的实际情况笼罩着一层面纱,但科学家们在分析数据和画面后发现,朝鲜的技术已经非常高端。   “朝鲜的技术实力稳步提高。”在看完朝鲜公布的导弹发射画面后,日本前防卫厅技术研究本部第三研究所所长久保田浪之介作出了上述判断。   朝鲜所发射物体的轨道接近适合地球观测卫星等的特殊轨道,将物体投入该轨道,需要对途中飞行方向进行微调。多年来从事火箭开发的宇宙科学研究所名誉教授秋叶镣二郎表示:“可以说朝鲜掌握了飞行控制技术中比较难的部分。”   一、二级导弹下落前的用时比上次减少了3到6分钟,可以认为发射至相同高度的燃烧时间有所缩短。熟悉宇宙工程学的大同大学校长泽冈昭分析说:“这意味着朝鲜已经能够在短时间内燃烧掉大量燃料。推进力应该比上一次提升了20%左右。”   报道称,但朝鲜将搭载物送入绕地轨道,未让其下落。因此可以认为,朝鲜尚未完全掌握远程弹道导弹技术。其理由之一是,让导弹从宇宙空间再次进入大气层的技术非常难。再次进入大气层需要经受住1000度以上的高温,所以需要高端的耐热技术。相关的主题文章:

The trip to China is imperative (viewpoint) — Shanxi channel people’s network mine_清翼

Chinese trip, imperative (view) – Shanxi Channel – Chinese people.com.cn in a large number of students have set foot on American land, to learn, and strive to improve their life, at the same time, the United States China to more and more young people, students, there are a few go to work, and even a lot of retired people in to inquire about the China work and life. Although the number of people is far from the Chinese people who come to the United States, but the two governments are actively promoting, hoping to have more Americans learn Chinese, understand Chinese culture, including encouraging more Americans to study and live in China for a period of time. This is an imperative direction. People all over the world are running to the United States, which is the trend of the past few decades, the reason is very simple, the United States in the Second World War after the rapid development, attracting a large number of talents. With the development and change of China in recent decades, its remarkable achievements will naturally attract the attention and curiosity from the world, including the Americans’ keen attention. For a variety of reasons, people who live in the United States can not keep up with the rapid development of china. Only to be keenly aware of the rapid development of Chinese personally on the scene, the understanding of a real China. Since it is a real China, it must include all aspects, at least the objective existence of both positive and negative sides. It is not a single distorted image after being beautified or vilified. A real understanding of a rapidly changing China is not only the wish of many Americans today, but also the inevitable outcome of the Americans who have been lucky enough to have been to china. As time goes on, there will be more and more people like this. China and the United States government should also continue to strengthen communication and cooperation in this regard, so that more Americans have the opportunity to visit, study and live in China for a period of time. This is not only necessary to promote mutual understanding between China and the United States, but also the only way to maintain world peace and development. Mutual understanding is not enough, it will inevitably produce separation, misunderstanding and conflict. The peace between China and the United States is neither peaceful nor peaceful. Fortunately, most Americans who have been to China feel satisfied with their trip to China, and feel that it is right to go to China without regret. From my personal direct and indirect understanding, over the past twenty or thirty years, the general feelings of most Americans who have been to China are concentrated in three aspects. First, they generally feel the friendliness and enthusiasm of the Chinese people. The two is that they have witnessed the latest development of China, especially when these new technologies and new developments are based on the very backward foundation. Three they are surprised to find that in fact there are a lot of culture between China and the harmony, substantially coincides with the identity and values of the. China is probably the most unfamiliar and familiar place they’ve ever been to. A blind date at the hands of the people. If we carefully reflect the true meaning and significance of these three aspects, we will find that this is actually the basic point we should maintain. Warmth and friendship are the fine traditions and virtues of the Chinese people. The progress and breakthrough of science and technology is the pride of Chinese people and government, and is also the goal that everybody continues to pursue. Sino American culture 中国之行,势在必行(观点)–山西频道–人民网 在大批中国留学生纷纷踏上美国土地,来学习、生活、努力提高自己的同时,去中国的美国年轻人也越来越多,有留学生,也有少量去工作的,甚至还有很多退休老人也在打听去中国工作、生活。虽然在人数上还远不能与来美国的中国人相比,但两国政府都在积极推动,希望能有更多的美国人学习汉语,了解中国文化,其中也包括鼓励更多的美国人到中国学习生活一段时间。 这是一个势在必行的大方向。全世界各地的人们纷纷往美国跑,这是过去几十年的历史潮流,原因很简单,美国在第二次世界大战后发展迅猛,吸引了大量人才。随着中国近几十年来的发展变化,其有目共睹的巨大成就,自然也会强烈地吸引来自世界的目光与好奇,包括美国人的热切关注。 由于各种原因,身居美国的人们,在认知上一时还跟不上中国的快速发展变化。只有身临其境,才能切身体会中国的快速发展,了解一个真实的中国。既然是真实的中国,就必然包括方方面面,至少是正负两面的客观存在,绝不是被美化或丑化之后的单一失真的形象。真切了解一个快速变化的中国,既是许多美国人今天的愿望,也是那些有幸已经去过中国的美国人所津津乐道的必然结果。随着时间的推移,这样的人会越来越多。 中美两国政府,也应该继续努力加强这方面的沟通与合作,让更多的美国人有机会到中国去实地考察、学习和生活一段时间。这不仅对增进中美两国人民之间的相互了解十分必要,也是维护世界和平发展的必由之路。相互了解不够,就必然会产生隔膜、误解和冲突。中美之间不太平,世界也就谈不上太平。 可喜的是,那些去过中国的美国人,大都对他们的中国之行感觉满意,觉得去中国是做对了,没有遗憾。从我个人直接和间接了解的情况看,过去二三十年间,大部分去过中国的美国人的普遍感受,集中体现在三个方面。一是他们普遍感受到了中国人民的友善和热情。二是他们目睹了中国的最新发展,特别是当这些新科技、新发展建立在原有十分落后的基础之上,就更令人瞩目。三是他们惊奇地发现,中美之间其实存在着大量文化方面的水乳交融,以及价值观方面的基本重合与认同。中国很可能是他们去过的最陌生同时也是最熟悉的地方。 国之交在民相亲。如果我们认真回味这三个方面的真实含义和重要意义,就会发现这其实正是我们应当维护的基本点。热情友善是中国人民一向具有的优良传统与美德。科技进步与突破,是中国人民和政府的骄傲,也是大家继续追求的目标。中美文化的合作交流与交融,正是体现了人类文明进步发展的成果,代表了世界人民的共同向往,也是我中有你、你中有我、和平共处、多元发展的健康状态。 从美国方面来说,需要做的可能会更多。首先是政府必须继续鼓励本国国民了解世界、了解中国,通过教育国际化继续提高美国人民对外部世界的了解及尊重,为年轻人创造更多出国留学的机会。必须让更多的年轻人到中国去学习生活,亲身考察那里的一切。在充分自由地学习和了解的过程中,放飞自己的人生理想。由于世界多元化的进展和经济全球化的发展,年轻人去中国,已经成为一种战略性的选择。未来的世界变化将会证明,不去中国,才是遗憾。中国之行,势在必行。 (作者为美国安生文教交流基金会副主任)   《 人民日报 》( 2016年10月08日 11 版)相关的主题文章:
