Аннотация:The paper is devoted to put observational limits on the number of one dimensional
cosmological objects cosmic strings and other topological defects. Using the methods to
search for solitary string there were obtained the upper restrictions on individual string
tension depending on string model. It was shown that string can only be semilocal in the
range of 1 up to 5. The texure model is also legal. There are no strings with G mu / c^2 >
7.36 X 10^(-7).
