Изобрегеште относитс  к измеритель ной технике и может быть использовано при фенологических исследовани х; в растениеводстве .Isobregeste refers to the measuring technique and can be used in phenological studies; in crop production.

Известен способ измерени  площади плоских фигур произвольной формы, например листьэв растений, заключающийс  в том, что нанос т контур этой фигуры на бумагу, вырезают фигуру и по массе копии определ т ее площадь .l ,A known method for measuring the area of flat shapes of arbitrary shape, for example, leaves of plants, consists in cutting out the shape of this shape on paper, cutting out the shape and determining its area .l by the mass of the copy,

Недостатком этого способа  вл етс  низка  производительность и небольша  точность.The disadvantage of this method is low productivity and low accuracy.

Наиболее близким к изобретению  вл етс  способ измерени  площади дета-лей произволшой формы, заключающийс  в том, что измер емую деталь помещают между обкладками плоскопараллельного конденсатора с заданными параметрами и определ ют величину приращени -емкости , по которой суд т о площади 2.The closest to the invention is a method for measuring the area of parts of an arbitrary shape, namely, that the measured part is placed between the plates of a plane-parallel capacitor with the given parameters and the magnitude of the increment of capacitance is determined by which area 2 is judged.

Недостатком указанного способа  вл етс  невысока  точность измерени .The disadvantage of this method is the low measurement accuracy.

Цель изобретени  - повышение точнооти измерени . .The purpose of the invention is to increase the accuracy of measurement. .

Эта цель достигаетс  тем, что используют второй конденсатор с параметрами, отличными от Параметров первого, размещают между его обкладками измер емую деталь, определ ют величину изменени  емкости БтЬрЬгчГ конденсатора и по полученным данным определ ют площадьThis goal is achieved by using a second capacitor with parameters other than the parameters of the first one, placing the measured part between its plates, determining the magnitude of the change in capacitance Btbccc capacitor, and using the data obtained, determine the area
