Foreword
This section GB/T 2900 Part 61.
The partial modification of the use of IEC 60050-111.1996 "International Electrotechnical Vocabulary Physics and Chemistry" and their first single modification
(IEC 60050-111Amendment1.2005).
This part of IEC 60050-111.1996 and IEC 60050-111Amendment1.2005 compared, there is a technical difference.
--- This part of the increase in 111-13-29 definition "For systems without interaction with the outside world" content, give a more precise definition.
--- This section in Note 1 111-13-35 increases "when it is not caused by other changes" content, give a more precise definition.
--- This part of the increase of the "current flows" content in 111-15-18 definition. This definition is based on GB/T 2900.41-
2008 "Electrotechnical terminology primary cells and batteries" Edit.
--- This section adds "and the electrolyte contains hydrogen ion electrode composed of" content 111-15-31 definition, give a more accurate
definition.
--- This section pressure 111-15-32 definition to 100kPa. In IEC 60050-111, the pressure to "101325kPa".
This value is in accordance with GB 3102.8-1993 "physical chemistry and molecular physics quantities and units" Edit.
--- This part of the increase in 111-15-34 definition "interface and bulk solution" content, give a more precise definition.
This Part replaces GB/T 2900.61-2002 "Electrotechnical terminology physics and chemistry."
This section compared with the GB/T 2900.61-2002 main changes are as follows.
--- Increase the IEC 60050-111 first amendments (IEC 60050-111Amendment1.2005) the contents of that Part
2.6 points;
--- Remove the GB/T 2900.61-2002 in 111-13-01,111-13-02,111-13-03,111-13-04 and 111-13-05
5 item number, the corresponding contents to the terms and definitions in section 2.6, that this section 111-16-11,111-16-
08,111-16-12,111-16-10 and 111-16-13.
In this section relating to quantities and units of terminology and symbols GB 3100 ~ 3102-1993 "Quantities and units" are basically the same, individual differences
Department is defined in the corresponding described.
This part made possible coordination with the existing terms of national standards, the relevant standards are.
--- GB/T 2900.41-2008 Electrotechnical terminology cells and batteries;
--- GB/T 14733.3-1993 telecommunications term reliability, maintainability and quality of service;
--- GB/T 14733.9-1993 Terminology for telecommunications radio wave propagation;
--- GB/T 3187-1994 reliability, maintainability term;
--- GB/T 4597-1996 words tube.
This section and the National Committee for science and technology noun released "Physics term" coordinated.
No entry in this section, the term is consistent with IEC 60050-111.
This part of the National Technical Committee of Standardization Electrotechnical terminology and centralized.
This section is drafted. Mechanical Engineering Research Institute of Machine Productivity Promotion Center, Tsinghua University, Beijing University of Aeronautics and Astronautics, higher education out

Electrotechnical terminology physical and chemical
1 Scope
This section provides terms and definitions electrotechnical involved in physics and chemistry.
This section applies to all areas of science and technology involved in electrotechnology.
2 Terms and definitions
2.1 The concept of quantities and units
111-11-01
Qualitatively and quantitatively determine the difference between the properties of the phenomenon, object or substance.
Note 1. The term "amount" may refer to a broad sense of the amount (for example. length, time, mass, temperature, resistance, amount of substance concentration) or a specific amount (for example. given a long stick
Degree, given the resistance of the wire, a given amount of ethanol C2H5OH concentration of alcohol in the sample of material).
Note 2. The amount according to the relative size of the sort referred to the same kind of volume.
Note 3. The number of the same kind of volume can be combined into a weight class. E.g.
--- Power, heat, energy.
--- Thickness, circumference, wavelength.
Note 4. The International Standard IEC 60027 "Electrotechnical letter symbol" and the GB 3102 "Quantities and units" given the amount of symbols.
Note 5. The concept is still under study.
111-11-02
Equation showing the relationship between physical quantities.
111-11-03
In one set amount, according to the agreed amount considered to be independent of each other.
111-11-04
In one set amount, the amount of the basic amount by the quantity equation linked.
111-11-05
And all combinations of the basic amount of the export volume of the specified equations defined by a substantial amount.
111-11-06
dim
An amount made on behalf of a substantial amount of power factor indicates that the amount of product made in a constant expression.
Note 1. Example. In the basic amount of length, mass, and the amount of time in the system, respectively to the three basic factors L, M and representatives T, LMT-2 to force dimension; in this
The same amount in the system, ML-3 for the mass concentration and mass density dimension.
Note 2. Represents a substantial amount of these basic amount of the factor called "dimension."
Note 3. The details of the relevant algebra, see ISO 31-0.
Note 4. This concept is still under study.
