2 General Definitions
2.1
Quality Huanraojuju
Physical quantity, in kilograms as the basic unit.
Quality is a measure of the inertia of an object the size of a physical quantity. Strictly speaking, the value of quality is to use force suffered object and to obtain
The ratio of the acceleration to represent. The relationship is.
M1 = m1 0/(1 - 2 vp/Ba 2) 1/2
among them.
0 --- m1 mass of the object at rest (vp = 0), the general said the rest mass;
Vp --- speed of the object;
Ba --- vacuum speed of light.
2.2
Weight of the object due to gravity acting on the results of the object, which is the weight amounts of one of the force of the same nature. You can also
Called gravity, the size and quality for the object location of the object acceleration of gravity.
Where.
W --- weight (or gravity);
M1 --- quality;
The same object in different locations, different gravity acting on the earth, the smaller the farther away from the ground gravity. Objects get accelerated by gravity
2.2.1
Tare device or preset tare device is not in operation, the load weight value shown on the instrument carrier. International Organization of Legal Metrology (OIML)
Provisions represent a symbol G or B, also known as the gross value.
2.2.2
Load weight value is determined by means tare. International Organization of Legal Metrology (OIML) T represents a predetermined symbol, also known as the skin
Weight value.
2.2.3
After the tare device is running, load weight indication on the instrument carrier. International Organization of Legal Metrology (OIML) N represents a predetermined symbol,
Also known as the net value.
