Divergence, английский
- (дивергенция, расхождение) ситуация, в которой два или больше графиков дают расхождение в подтверждениях тенденций на рынке. например, ценовой график образует новый пик, по абсолютному значению превышающий предыдущий, но оцсцилятор этого не подтверждает.
- Дивергенция, расхождение [нарастание] колебаний; колебательная неустойчивость
- Дивергенция, т. е. ситуация, в которой два или больше графиков индексов дают расхождение с ценовым графиком.
- The angular measurement of laser beam spread with distance. the projected dot of a laser will increase in size the farther it is projected. laser divergence is measured in milliradians (mrad). dosimetry
- 1. a condition in which one eye points directly at the object of interest but the other does not 2. the process of moving apart to follow different courses 3. the amount of difference between two quantities, especially where the difference is unexpected 4. a deviation from a typical behaviour pattern or expressed wish
- The ability to use both eyes as a team and be able to turn the eyes out toward a far object.
- N 1 дифференциация; 2 дивергенция
- Расхождение; отклонение; геод. невязка
- A horizontal outflow of air.
- When two or more averages or indexes fail to show confirming trends.
- Term sometimes used to describe the spreading of ultrasonic waves beyond the near field. it is a function of transducer diameter and wavelength in the medium. see beam spread.
- Term sometimes used to describe the spreading of ultrasonic waves beyond the near field. it is a function of transducer diameter and wavelength in the medium.7 see beam spread. double-crystal technique: see pitch catch technique.
