在文中，徐直军强调了学术自由的重要性，论述了大学与企业的合作对于科技进步的关键作用，并表示华为在提供支持时并不期望能获得直接商业回报，研究成果通过教授、博士和研究生们的论文形式公开发布。他特别指出，任何基础研究项目要造福社会是一个艰辛而且漫长的过程，需要大学与企业紧密合作，需要无数科学家、工程师们长期艰苦奋斗，他们的努力和贡献应该受到尊重，而不是肆意指责。

全文如下：

不久前，几名美国国会议员严厉地批评了华为，还要求美国教育部长调查华为与美国大学的基础科研合作项目是否会对美国国家安全构成。我认为这些行为显示了他们对科学的无知。*近在接受媒体采访时，我提到这些批评是“无知的”。

我并不想进行人身攻击。相反，我只是希望强调学术自由的重要性。学术自由是现代大学的基本属性，是一切科技进步的基石，有助于培养下一代科研人才。

学术自由是高等教育的基石。正是由于美国大学能保持学术自由，不受政治和外部因素干扰，才吸纳了全球*优秀的人才到美国学习和研究，成就了美国的全球技术领导者地位。

我是一位从事过基础研究的工学博士。根据美国国家科学基金会的定义，“基础研究”是指“致力于获取新知识或理念，但不考虑具体流程或产品应用的活动”。

企业的研发活动主要聚焦商业应用，而大学则关注数学、算法、材料科学等不太可能创造收益的应用。即使某个研究项目*终会产生回报，从理论研究到商业化可能需要花费数十年时间。

大学与企业的合作能够有效缩短这个过程。企业、学术界和研究机构之间的知识和资源交换（也称“知识转移”）已经成为推动科技进步的关键动力。

然而，过去十年间，美国联邦政府向大学研究项目提供的资金在持续下降，如今占大学总研究资金的比例低于50%。

余下的大部分资金来自华为等企业提供的赞助。华为向美国大学提供的研究资金相对有限，去年约为1,000万美元。但我们提供的支持正是大学所需要的，包括资金、场地和实验设备等支持。同时，我们也为在校研究生、大学生们创造了丰富的培训和实践机会。在提供这些支持的时候，我们并不期望能获得直接商业回报。

华为资助美国大学进行基础研究，研究成果将造福大众，并不会像外界批评所说的那样会对美国构。

我们与大学的研究成果通过教授、博士和研究生们的论文形式公开发布。

2017年，华为在研发领域投入138亿美元，过去十年华为的全球研发总投入超过600亿美元。华为在全球各国已经有近8万件获得授权，其中在美国授权近一万件，许多还是电信业的基本，这对数字经济发展也是一个贡献。

任何基础研究项目要造福社会是一个艰辛而且漫长的过程，需要大学与企业紧密合作，需要无数科学家、工程师们长期艰苦奋斗，他们的努力和贡献应该受到尊重，而不是肆意指责。

一个开放的政治领袖，应该要致力于维护美国大学的学术自由，才能推动美国的科技进步。同时，政治领袖要像全球科学家一样具备深度洞察力、好奇心和实事求是精神

With the rapid development of Internet business ａnd the increasingly large scale of network, the traditional maintenance mode will face the problem of low operation ａnd maintenance efficiency in response to new business management requirements. Jiangsu Unicom in network operation ａnd maintenance to digital, intelligent transformation, ａnd HUAWEI in the direction of intelligent operation ａnd maintenance cooperation, through the IES (Infrastructure enabling system) intelligent scheduling solution to realize the unified alarm monitoring, diagnosis ａnd self-healing of multi vendor products in the wireless domain of the province, the success rate of fault diagnosis is 90+%, greatly raised. Increase the efficiency of operation ａnd maintenance.

Based on a profound understanding of business, Jiangsu Unicom, through a large number of operation ａnd maintenance data analysis, divided the project goals in a professional ａnd stage stage, ａnd jointly promoted the successful deployment of the IES intelligent scheduling solution with HUAWEI.

HUAWEI has the operation ａnd maintenance experience of the global 1500+ network ａnd the perfect network operation ａnd maintenance fault tree model. The intelligent IES scheduling solution can make use of the model to analyze ａnd delimit the alarm of multi vendor products in the fields of wireless ａnd IPRAN transmission, ａnd realize the root cause analysis ａnd automatic healing.

With the development of technology ａnd business, the network becomes more complex ａnd the demand of digital operation is becoming more ａnd more urgent. The successful practice of HUAWEI ａnd Jiangsu Unicom IES intelligent scheduling platform provides valuable experience for the transformation of industry ａnd maintenance. In the future, it will continue to enrich the application scene, help the operators to further improve the efficiency of operation ａnd maintenance, guarantee the efficiency of operation ａnd maintenance. The network is stable. On the morning of July 23rd, Beijing time (Jiang Junmu), in response to some American congressmen＇s criticism of HUAWEI＇s cooperation with the University, Xu Zhijun, chairman of HUAWEI, refuted in the financial times, calling it "ill-informed", ａnd focusing on the outside world. Information - HUAWEI supports US universities for basic research, which will benefit the public ａnd will not pose a threat to the United States.

In this article, Xu stressed the importance of academic freedom ａnd discussed the key role of cooperation between universities ａnd enterprises for the progress of science ａnd technology, ａnd indicated that HUAWEI did not expect to obtain direct commercial returns when providing support, ａnd the research results were published in the form of professors, doctorates ａnd graduate students. He pointed out in particular that it is an arduous ａnd long process for any basic research project to benefit the society. It requires a close cooperation between universities ａnd enterprises, which requires a long ａnd hard struggle of scientists ａnd engineers, ａnd their efforts ａnd contributions should be respected rather than accusations.

The full text is as follows:

Not long ago, several U.S. congressmen severely criticized HUAWEI ａnd asked the Secretary of education to investigate whether HUAWEI＇s basic scientific research partnership with American universities would pose a threat to the security of the United States. I think these behaviors show their ignorance of science. In recent interviews with the media, I mentioned that these criticisms were "ignorant".

I don＇t want to have a personal attack. On the contrary, I just want to emphasize the importance of academic freedom. Academic freedom is the basic attribute of modern universities, the cornerstone of all scientific ａnd technological progress, ａnd helps to train the next generation of scientific research personnel.

Academic freedom is the cornerstone of higher education. It is because American universities can maintain academic freedom ａnd are not disturbed by political ａnd external factors, so that the best talents in the world have been studied ａnd studied in the United States, ａnd the status of the global technology leaders in the United States has been achieved.

I am a doctor of Engineering in basic research. According to the National Science Foundation (National Science Foundation), "basic research" refers to "activities committed to acquiring new knowledge or ideas, but not considering specific processes or product applications."

The R & D activities of enterprises mainly focus on commercial applications, while universities are concerned about applications such as mathematics, algorithms, materials science ａnd so on, which are unlikely to generate revenue. Even if a research project will eventually yield a return, it may take several decades from theoretical research to commercialization.

University ａnd enterprise cooperation can effectively shorten the process. Knowledge ａnd resource exchange among enterprises, academia ａnd research institutions (also known as "knowledge transfer") have become the key driving force for scientific ａnd technological progress.

However, over the past ten years, the federal government＇s funding for university research projects has continued to decline, ａnd now it accounts for less than 50% of the total university research funding.

Most of the rest comes from sponsorship from companies such as HUAWEI. HUAWEI＇s research funding to American universities is relatively limited, which was about $10 million last year. But the support we provide is exactly what the university needs, including funding, venues ａnd laboratory equipment. At the same time, we have created abundant training ａnd practice opportunities for postgraduates ａnd university students. When providing these support, we do not expect to get direct business returns.

HUAWEI supports American universities for basic research, which will benefit the public ａnd will not pose a threat to the United States, as critics say.

Our research results are published publicly in the form of papers written by professors, doctorates ａnd postgraduates.

In 2017, HUAWEI invested 13 billion 800 million US dollars in R & D field. Over the past ten years, HUAWEI has invested more than $60 billion in global research ａnd development. HUAWEI has been authorized by nearly 80 thousand patents around the world, including nearly ten thousand patents authorized in the United States, ａnd many of the basic patents in the telecommunications industry, which is also a contribution to the development of the digital economy.

It is an arduous ａnd long process for any basic research project to benefit the society. It requires a close cooperation between universities ａnd enterprises, which requires a long ａnd hard struggle of scientists ａnd engineers, ａnd their efforts ａnd contributions should be respected.
