摘要：
Improved canonical superenergy tensors and integral superenergetic quantities which were introduced be the author some years ago are applied for Friedman universes. The analysis shows that the canonical superenergetic quantities are positive-definite in the considered case and have much better transformational and physical properties than the canonical energetic quantities.
