Modified Method
During the experiment, we may sizes of the drops each time, thus reduce the precision of value of the surface tension. The stalagmometric method was currently improved by S. V. Chichkanov and his colleagues that they modify the experiment to measure the weight of the drops in a fixed number rather than directly measure the number of the drops. The modified method to determine the surface tension based on the weight of the drops in a fixed number can be more precise than the original method based on the number of drops, especially for the fluid which surface is highly active. The advantage of the modified method is that it actually get more precise value of the surface tension and reduce the duration of experiments.

Famous quotes containing the words modified and/or method:
“Poetry presents indivisible wholes of human consciousness, modified and ordered by the stringent requirements of form. Prose, aiming at a definite and concrete goal, generally suppresses everything inessential to its purpose; poetry, existing only to exhibit itself as an aesthetic object, aims only at completeness and perfection of form.”
—Richard Harter Fogle, U.S. critic, educator. The Imagery of Keats and Shelley, ch. 1, University of North Carolina Press (1949)
“Government by average opinion is merely a circuitous method of going to the devil; those who profess to lead but in fact slavishly follow this average opinion are simply the fastest runners and the loudest squeakers of the herd which is rushing blindly down to its destruction.”
—Thomas Henry Huxley (1825–95)
