[en] A review presents current methods of microcalorimetry (except for differential ones) used in low-temperature physics. A criterion is indicated for useful application of microcalorimetric techniques, and a brief chronology of works is given on elaboration and application of low-temperature methods in experimental physics. The basic microcalorimetric methods are outlined that are employed in the low temperature range (0.05-300 K): the AC-method, relaxation method, method of continuous heating (cooling dowin), diffusion method (method of temperature waves), and iterative method. A more detailed methematical analysis is given for the last three methods. The advantages and shortcomings of each method are considered. The spheres of application are indicated. The design features of microcalorimeters are given a special attention. Various microcalorimetric methods are compared, and conditions are indicated for realising a 1% accuracy of the heat capacity measurement. The trends of low-temperature microcalorimetry evolution are discussed., as well as other problems that are to be solved
