This is a map of Warcraft.

It is also the map with the highest occurrence rate of 1v 1 platform in China.

Engineering index (EI) was founded in 1884, which is a well-known comprehensive retrieval tool for engineering technology published by engineering information company. EI is published every month 1 issue, with abstracts from 13000 to 14000; Each issue is accompanied by a subject index and an author index; There is also an annual volume and an annual index every year, and the annual index also increases the author unit index. There are print (periodicals), electronic (tapes) and microfilm. EI has selected more than 3,500 periodicals in 15 languages and more than 3,500 conference proceedings, scientific reports, standards, books and other publications in dozens of countries and regions around the world. More than 654.38+600,000 articles are reported every year. The collected literature covers almost all fields of engineering technology. For example: electric power, electrician, electronics, automatic control, mining and metallurgy, metal technology, machinery manufacturing, civil engineering, water conservancy and so on. It has the characteristics of strong comprehensiveness, wide data sources, wide geographical coverage, large amount of reports, high quality of reports and strong authority.

Ei Compendex is the earliest source of engineering abstracts in the world. The index information of 500,000 abstracts added to Ei Compendex database every year comes from 565,438+000 engineering journals, conference collections and technical reports. The documents collected by Ei Compendex cover all engineering fields, of which about 22% are conference documents and 90% are in English.

Ei Company began to collect China periodicals from 1992. 1998 Ei Set up Ei China Mirror Station in Tsinghua University Library.

Before 2009, EI divided its collected papers into two grades. 1, EI Compendex index summary (also known as core data). Including the title and abstract of the paper, indexing and deep processing with subject words and classification numbers. Whether there are subject words and classification numbers is the only sign to judge whether a paper is officially included in EI. 2. The header record on the first page of 2.EI (also called non-core data). It is mainly reported in the form of title records. Some also have abstracts, but they have not been further processed, and there are no subject words and classification numbers. Therefore, the abstract on the first page is not necessarily a formal entry into EI.

Since June 65438+ 10, 2009, China periodical data collected in Ei Compendex database are no longer divided into core data and non-core data. [ 1]

EI's requirements for manuscript content and academic level

1, engineering papers with high academic level, including disciplines:

-Mechanical engineering, electromechanical engineering, ship engineering, manufacturing technology, etc. ;

-Mining, metallurgy, materials engineering, metal materials, nonferrous metals, ceramics, plastics and polymer engineering.

-Civil engineering, architectural engineering, structural engineering, ocean engineering, water conservancy engineering, etc. ;

Electrical engineering, power plant, electronic engineering, communication, automatic control, computer, computing technology, software, aerospace technology, etc. ;

-Chemical engineering, petrochemical industry, combustion technology, biotechnology, light industry, textile and food industry;

-Project management.

2. Projects supported by the National Natural Science Foundation, key scientific and technological projects and "863" high-tech projects.

3. The paper has reached the international advanced level and the results are innovative.

EI does not include papers on pure basic theory.

[Edit this paragraph] Ecological Infrastructure Ecological Infrastructure (EI)

Under the background of rapid urbanization in China, the state and urban planning departments attach great importance to the establishment of landscape ecological security pattern in view of a series of problems such as disorderly urban expansion, waste of land resources and serious damage to land life system. Avoid unnecessary redundant construction; Therefore, environmental impact assessment has become a hot issue in urban planning in recent years.

EI refers to the natural system that regions and cities depend on, and it is a key network land spatial pattern that integrates multiple functions of the ecosystem, including water conservation, drought and flood regulation, biodiversity protection, local cultural protection, leisure and aesthetic experience. In the research method, with the help of GIS technology, we can simulate and analyze the landscape process (including urban expansion, spatial movement of species, flow of water and wind, diffusion of disaster process, etc.). ) to judge the landscape security pattern (SP) of different processes, and to construct ecological infrastructure by comprehensively superimposing the security patterns of different processes. It is an important network land space model, which integrates various functions of the ecosystem, including water conservation, drought and flood regulation, biodiversity protection, local cultural protection, leisure and aesthetic experience.

[Edit this paragraph] Echo Islands for the battle map-.

EI is also the abbreviation of the famous battle map Echo Isles in Warcraft, which is a two-person battle map. The two main mines in the figure are located at 1 1 point and 1 point respectively (yellow dots marked with red and blue in the figure), and the corresponding sub-mines are at 8 o'clock and 4 o'clock. The three neutral buildings in the middle of the map are: market, pub and goblin shop from top to bottom. The neutral buildings at 9 o'clock and 3 o'clock on the map are mercenary camps.

Internet Language (Japan)

EI, if the two letters are connected, it becomes the "day" in Chinese characters. Some netizens euphemistically expressed this meaning with "eyah".

Mass spectrometry (chemical engineering, detection)

Electron impact source

EI, also short for emotional intelligence. That is emotional intelligence.
