东风-61导弹:全球覆盖的战略利器

  “全球覆盖,震撼登场!” 在2025年9月3日纪念中国人民抗日战争暨世界反法西斯战争胜利80周年阅兵(简称“九三阅兵”)中,东风-61(DF-61)作为核导弹第一方队的核心装备首次亮相,官方解说突出其全球打击能力、末端高超音速特性和多弹头设计,彰显中国战略核力量的新高度。 东风-61导弹概述 东风-61(Dongfeng-61,简称DF-61)是中国最新一代陆基洲际弹道导弹(ICBM),隶属东风系列导弹家族。它在2025年9月3日的阅兵中首次公开,与“惊雷-1”空基远程导弹、“巨浪-3”潜射洲际导弹及“东风-31BJ”新型陆基洲际导弹共同亮相,标志着中国陆、海、空基“三位一体”核力量的全面展示。 DF-61被认为是继东风-41(DF-41)后的重大升级,是中国最先进的洲际导弹之一,具备全球打击、全时戒备和强大威慑能力。它采用机动发射平台(TEL),突出高机动性与突防能力,所有受阅装备均为国产现役主战装备。作为战略“王牌”,DF-61旨在维护国家主权与民族尊严。 发展历史与背景 东风系列导弹始于20世纪50年代,早期受苏联技术启发(如仿制R-2导弹)。DF-61编号跳过DF-51,可能出于保密或技术跨越考虑。历史上,1966年曾有一个“东风-61”短程战术导弹项目,因固体燃料等技术难题中止。 现代DF-61被视为DF-41的升级或继任型号。DF-41于2019年国庆阅兵亮相,射程12,000-15,000公里,可携带10枚分导式多弹头(MIRV)。DF-61可能融合了高超音速滑翔技术(HGV)和先进制导系统,强调全球覆盖与突防能力,由中国人民解放军火箭军(PLARF)装备,属于第二或第三代战略导弹。 技术规格与性能 由于官方披露有限,参数多来自阅兵报道、专家推测及开源情报,存在一定差异。以下为主要规格汇总: 射程 :覆盖全球,约14,000公里以上(部分夸张报道称42,000公里,接近地球周长,可能性低)。可打击全球主要城市,包括美国全境。 速度 :末端速度约55马赫(约67,000 km/h,高超音速),远超现有反导系统拦截能力,采用高超音速滑翔技术(HGV)。 弹头与载荷 :可携带10-18枚分导式核弹头(MIRV),每枚当量约120万吨TNT(广岛原子弹的80倍),总载荷约2,500 kg,支持核或常规弹头。 推进系统 :三级固体燃料发动机,支持大气...

LingU 畢業要求??IELTS 是什麼??

The International English Language Testing System (IELTS) is a standardized test designed to evaluate the English language proficiency of non-native speakers who wish to study, work, or migrate to countries where English is the primary language of communication.

The IELTS exam assesses a candidate's language skills in four areas:

  1. Listening - Candidates listen to four recorded texts, monologues, and conversations, and answer questions based on what they hear.

  2. Reading - Candidates read three long passages and answer questions based on comprehension, understanding of vocabulary, and the ability to identify the writer's purpose and opinion.

  3. Writing - Candidates are evaluated on their ability to write two essays, one of which is an argumentative essay, and the other is a descriptive essay, based on the given topic.

  4. Speaking - Candidates engage in a face-to-face interview with a certified IELTS examiner and are evaluated on their fluency, pronunciation, grammar, and vocabulary.

The IELTS exam is available in two formats: Academic and General TrainingThe Academic version is designed for students who wish to study at the undergraduate or postgraduate level in an English-speaking country, while the General Training version is intended for those who want to work or migrate to an English-speaking country.


IELTS scores are reported on a nine-band scale, with a score of 9 being the highest and 1 being the lowest. The score is based on the candidate's performance in each of the four sections, and the overall score is the average of the four individual scores. The IELTS score is valid for two years from the date of the test.


The IELTS test is important to university students for several reasons:

  1. Admission: Many universities and colleges require non-native speakers of English to provide proof of their English language proficiency as part of the admissions process. The IELTS test is widely accepted by universities around the world as evidence of English language proficiency, and a good IELTS score can help students gain admission to their desired academic program.

  2. Academic Success: University students who are non-native speakers of English may struggle in academic coursework if they do not have a strong command of the English language. The IELTS test assesses a student's ability to communicate effectively in English, including listening, speaking, reading, and writing. By taking the IELTS test and achieving a good score, students can demonstrate that they have the language skills necessary to succeed in their academic coursework.

  3. Career Opportunities: In today's globalized world, many employers require job candidates to have strong English language skills. By achieving a good score on the IELTS test, university students can demonstrate to potential employers that they have the language skills necessary to communicate effectively in an English-speaking workplace.

  4. Study Abroad: Many university students choose to study abroad as part of their academic program. In order to do so, they may need to provide proof of their English language proficiency. The IELTS test is accepted by many universities around the world as evidence of English language proficiency, making it an important tool for students who wish to study abroad.

Overall, the IELTS test is an important tool for university students who are non-native speakers of English. By achieving a good score on the IELTS test, students can enhance their academic successcareer opportunities, and ability to study abroad.
