  کو‌آنتومیدن   
kuântomidan (#)

Fr.: quantifier   

Math.: To restrict a variable quantity to discrete values rather than to a continuous set of values.
Physics: To change the description of a physical system from classical to quantum-mechanical, usually resulting in discrete values for observable quantities, as energy or angular momentum.

From quant(um) + → -ize.

From kuântom, → quantum, + -idan infinitive suffix.

quantized
  کو‌آنتومیده   
kuântomidé (#)

Fr.: quantifié

second quantization
  کو‌آنتومش ِ دوم   
kuântomeš-e dovom

Fr.: deuxième quantification   

In quantum mechanics, the quantization of the field that replaces potential in Newtonian mechanics, whereby the field variables become operators from which the creation (of particle) operators and destruction operators can be constructed.

second; → quantization.

semantic
  چماریک   
cemârik

Fr.: sémantique   

1) Of, pertaining to, or arising from the different meanings of words or other signs and symbols.
2) Of or pertaining to → semantics.

The region is centered near 25 degrees South 50 degrees West, close to the Atlantic coast of Brazil. The excess of trapped energetic particles in that region presents a problem for satellites in orbit around the Earth.

south; → Atlantic; → anomaly.

substantive
  زیریستین   
ziristin

Fr.: substantif   

Grammar: A word or word group functioning syntactically as a noun. Substantives include nouns and → nominals.
