Explanation of the noun modulus! Fineness modulus noun explained

Industrial definition: The indexing circle of the gear is the benchmark for designing and calculating the size of each part of the gear, and the circumference of the indexing circle of the gear = d=z p, so the diameter of the dividing circle d=z p.

Chemical definition: The ratio of moles. (For example, the chemical formula is R2O·N SiO2, and N is the ratio of SiO2 to R2O moles, which is called the modulus of R2O·N SiO2.) ）

Modulus: The indexing circle of the gear is the benchmark for designing and calculating the size of each part of the gear, and the circumference of the indexing circle of the gear = d=z p, so the diameter of the indexing circle is scored.

d=z p/π

Since it is an irrational number in the above equation, it is not convenient to locate the indexing circle as a reference. In order to facilitate calculation, manufacturing and inspection, the ratio p is artificially defined as some simple numerical value, and this ratio is called modulus (module), which is represented by m.

Architectural modulus. The building modulus refers to the standard size unit selected in the architectural design. It is the basis for the scale coordination of various departments such as architectural design, building construction, building materials and products, building equipment, and building components.

Just like any size, the building components cannot be standardized, and it is difficult to unify.

m fuzzy mathematics. Probably, I heard from the teacher!

The standard size unit selected for the building and its components (or assemblies) is used as a value-added unit in scale coordination to become the building modulus unit.

At present, all countries in the world use 100mm as the basic modulus value, and its symbol is m, that is, 1m=100mm.

Explanation of fineness.

fineness]

Relative width, relative diameter, thread density, or weight per unit length (e.g., of a fiber or thread) expressed in some unit

Words and words are broken down.

Explanation of fine fine (fine) ì small-grained, as opposed to "coarse": fine sand. Fine noodles.

Fine chips. Long strip thing Small diameter: thin line.

Filaments are in short supply. Thin eyebrows. Thin water flows.

Delicate: fine porcelain. Muslin.

Joinery. Careful work. The sound is small:

The voice is thin. Thorough and thorough: Carefully .

Concentration. Units of electrical energy,

A norm-referenced test is a test that uses norms to explain individual test scores, and it measures the mental level of an individual in terms of the mental level of a group. The main purpose of the norm-referenced test is to compare the performance of the test subject with the other test subjects in the stool chain closure of the group, so as to distinguish between different test subjects and determine the relative position of each test subject's mental level in the population. Many of the early educational and intelligence tests were norm-referenced tests.

Test items are required to have appropriate difficulty and a certain degree of discrimination, such as intelligence tests, aptitude tests, etc. Commonly used norm reference scales include the Percent Rating Scale, the Standard Score (Z) Scale, the T-Scale, the Ratio Intelligence Quotient Scale, the Dispersion Intelligence Quotient Table, and the Standard 9 Scale.

Extended information] The measurement of the relative psychological development level of the subjects in the norm-referenced test depends on the establishment of the norm, and the regular jujube crack mode is established on the basis of the standardized sample, so the norm and the standardized sample are two important concepts here.

Norm. The norm is a reference system for the evaluation of test results with reference points and units established according to the test results of standardized samples and after certain statistical technology processing.

Explanation of norms.

Ordinary scale. "Anthology: Zuo Si Wu Dufu" Hongge Lianjia, the giant threshold is connected, the flying clouds cover the sea, and the production is not a model. Zhang Milling Note:

Flying away from the clouds, the name of the building on the ship, its height covers the sea, there are many words, all carved and decorated, and its system is very model. ”

Word decomposition Explanation of often á long-lasting, constant: constant. Constants (also known as "constants").

Parameters, also called parametric variables.

is a variable. When we study the current problem, we are concerned with the changes in certain variables and the interrelationships between them, one or some of which are called independent variables.

The other or others are called dependent variables.

If we introduce one or more variables to describe the change between the independent variable and the dependent variable, the introduced variable is not the variable that must be studied in the current problem, and we call such a variable a parameter or parameter. English name: parameter

Statistics are variables used in statistical theory to analyze and test data.

A macroquantity is a statistical average of a large number of microquantities.

It should be pointed out that the physical quantities that describe the macroscopic world, such as velocity and kinetic energy, can actually be said to be macroscopic quantities, but macroscopic quantities do not all have the nature of statistical averages, so macroscopic quantities are not all statistics
