Rich selection of textures and colors meet different decoration requirements, giving the city and the buildings a new look.
The quality of a scientific journal is closely related to its ability to implement international and national standards. Order No. 12 issued by the State Science and Technology Commission and the Press and Publication Administration on June 5, 1991, stipulates that the provisions of Article 22 of Chapter 4 of the Administrative Measures for Scientific and Technical Journals, which came into effect on July 1, 1991, Scientific and technical journals should implement relevant international standards, national standards and legal measurement units to standardize and standardize the editing and publishing of journals. The time has passed in 2002. From the results of reviewing more than a dozen textile science and technology journals, It is not optimistic. Except for 2~3 kinds of textile journals which implement the standards better, the rest have more or less problems. In order to make China's textile science and technology journals in line with international standards, in addition to the opening, cover design, printing, In terms of finishing, we must vigorously implement standards and specifications to further improve the overall quality of scientific and technical journals in the textile industry.
In addition to sharing some standards with other industries, the textile industry has its own professional standards. The author points out some problems in the implementation standards of textile science and technology journals in terms of professional standards and sharing standards, so as to be consulted by peers.
root.
(2) The textile industry expresses the unevenness of the linear density, elongation, strength, and dryness of the measured fiber or yarn, and is usually characterized by a coefficient of variation. And the expression of the coefficient of variation in -93: the variable symbol is CV, the unit is %, and the following indicates that the standard is not met: cv%CV%cV% (3) The mass specified in GB310.2 divided by the length is the linear density. In the textile industry, the quality of a fiber or yarn defined by 1000m is 1g, which is called 1tex. Therefore, the thickness of fiber or yarn is expressed by linear density, and GB/T3102.3-93 uses Pt as a variable symbol, and ISO02064 - In 1990, Tt (normal body) is used as the variable symbol. The author tends to use Tt as the variable symbol of linear density. The unit symbol is tex or its multiple or fractional unit. The Chinese symbol of the unit name is special. In the journal, there are mainly the following points for the non-standard and non-standard linear density: the unit symbol is changed to tex according to the standard, and the Chinese name of the quantity is still fineness, fineness, yarn number and yarn count.
The standard unit and non-standard unit symbols are incorrectly written. tex is written as Tex, D is written as d, and Nm is written as awake.
(d) In order to characterize the ability of fibers, yarns and fabrics to withstand external forces, it is usually expressed by two indicators: breaking strength and breaking strength.
1-97 specifies the breaking force measured when the single fiber (or single yarn) sample is stretched to break, the unit symbol is expressed by cN; the breaking strength refers to the ratio of the breaking strength of the material to its linear density, the unit symbol is cN/tex is indicated. The non-standard representation of strength and strength mainly has the following points.
The Chinese name is called chaos, the strength is called intensity, and the intensity is called unit intensity. Some journals call strength as strong.
3. The unit symbol is written incorrectly, such as CN, CN/tex. or Chinese name: g/den.
(5) The quality of the fabric per square meter to characterize the thickness, weight and weight of the fabric. The mass per square meter of fabric is referred to as the areal density according to the standard. Journals that are strictly enforced by standards are extremely individual. The Chinese name whose surface density is not standard is expressed as follows: weight, plane density, square meter weight, square meter weight.
(6) The name of the composite twill weave in the woven fabric, and the form of the commonly used fractions indicates the interlacing rule of the dropped yarn in the fabric tissue cycle. The name of the composite twill in GB 13774-92 is expressed as: and some journals often print this fraction as 23, 232. (7) The number of turns specified in GB8693-88 refers to the number of twists per twist of the yarn, the unit symbol isæ»/m. In some journals, the unit symbol of æ» is not in accordance with the standard. GB 8*4-88 stipulates that the direction of single yarn, sliver and roving is indicated by the capital letter "SV*Z*", while in some journals, S and Z are printed in italics or lowercase.
In addition to problems in the textile profession, there are also many non-standard and non-standard places.
(1) The positive italic arrangement of variable symbols and unit symbols is incorrect. The variable symbol is printed as a normal body and the unit symbol is printed in italics. If some journals print the pH, sin, differential number d, and transpose symbol T in italics, this does not meet national standards.
(2) The units that have been abandoned are used. For example, the unit of tension is expressed as dyne, g, and the unit of pressure is expressed as 8/la 2, 1 free/2 New Zealand\311 (atmospheric pressure), and the unit symbol of volume is l, ml. The standard representation: the unit symbol of the tension is cN, N, the unit symbol of the pressure is Pa, the unit symbol of the volume is L. For the dimension is one, the unit is the quantity of 1, without specifying the nature of the quantity, but for the " The % variable symbol is incorrectly printed, such as pressure p, distance s, velocity v, acceleration a is P, S, VA. (5) The unit of the same paper, sometimes with the Chinese name, sometimes with the unit symbol, or Chinese The name is mixed with the unit symbol.
(vi) Non-standardization of numerical ranges and tolerances.
GB3102.il-93 clearly stipulates that the numerical range number is that some journals still use a word line "one" to indicate the value range. Since the word line is easily confused with the minus sign "one" and the chemical key "one", in the scientific and technical journals, the value range should be used when the parameter is the same as the unit of tolerance, the unit can be written only once. If the standard indicates: (70* 1) *C, mistakenly written as 70*1*C or 70*C*1°C. The percentage of writing is repeated. After each percentage, “%†should be repeated. For example, 3~5% is written incorrectly, standard Expressed as 3%~5%. When representing the center value with percent tolerance, the percent sign "%" only needs to be written once, and the center value and tolerance before "%" should be enclosed in parentheses. (3±1)%, but some miswritten as 3%*1% or 3±1%. The heading of the vertical and horizontal coordinates in the figure consists of the name or symbol of the physical quantity and the corresponding unit. The symbol of the physical quantity is the italic letter, the unit The symbol is a normal body. The quantity is separated from the unit by a diagonal line V", such as the standard wording P/kW/gXm-2, and P(kW), PAW is a non-standard writing method.
The direction of the axis. Only when the coordinate axis represents a qualitative variable, and the specific value is not given, the top of the coordinate axis should draw an arrow in the direction of the quantity. Some textile science and technology journals, when given the value of the mark, add an arrow to the coordinate axis, which is not in line with the standard.
In order to improve the quality of scientific and technical journals in the textile industry, editors should strengthen their understanding of relevant national standards, further familiarize themselves with and understand national standards, and then implement standards to standardize and standardize our journal publishing work.
