В работе предложен критерий для проверки гипотезы f1(x) = kf2'(x). Он основан на численном интегрировании f1(x) методом трапеций и расчете коэффициента корреляции Пирсона между полученным рядом и значениями f2(x). The test for hypothesis checking about the presence of f1(x) = kf2'(x) type statistical relation is proposed. It is based on numerical integration of f1(x) by trapezium method and и calculation of Pearson correlation coefficient between obtained series and f2(x)values.

Effect of environmental pollution with a cationic surface-active substance on algae and Fagopyrum esculentum sprouts. – The Soviet Journal of Ecology [ISSN 00967807; later the journal was entitled: Russian Journal of Ecology]. 1990. Vol. 21. No.2, p. 79-81. http://scipeople.com/publication/70248/ 3 tables. Bibliogr. 10 refs. [in collaboration: Ostroumov S.A., Tret’yakova A.N. ). [At that moment of time the journal was published by Plenum Publishing Corporation, 233 Spring St., N.Y., N.Y. 10013; the reference number of the publication published at the first page of the paper: 0096-7807/90/2102-0079]. The effects of environmental pollution with a cationic surface-active substance (surfactant tetradecyltrimethylammonium bromide TDTMA) on certain cyanobacteria and algae - cyanobacteria Nostoc muscorum Ag, strain 33 isolated from the soil in the Kirov Oblast (Region); green algae Bracteacoccus minor (Chodat) Petrova, strain 200 and strain 219 (the strain 219 was isolated from the volcanic ash collected next to Tyatya Volcano, island of Kunashir) - was investigated. Their sensitivity to that surfactant TDTMA was compared with the sensitivity of a test based on the use of terrestrial plants. The algal experiments were performed with aquatic and soil cultures. The experiments with terrestrial plants used the earlier-developed method with seedlings of Fagopyrum esculentum Moench. TDTMA at concentrations 1 mg/L and above produced some negative effects on cyanobacteria and algae in aquatic cultures. TDTMA at concentrations 50 mg/L and above produced some negative effects on cyanobacteria and algae (diatoms) in soil cultures. TDTMA at a concentration 100 mg/L produced some negative effects on all organisms tested in the soil cultures. TDTMA at a concentration 100 mg/L decreased the number of cells per 1 g of soil; the decrease was observed for cyanobacteria, green algae, and diatoms. The experiments revealed the higher sensitivity of the test with the aquatic algal cultures.
