Disclosed is a new method and compositions from the method consisting of block copolycarbonatephosphonates that exhibit an excellent combination of flame resistance, hydrolytic stability, high Tg, low melt viscosity, low color and high toughness. According to the characters of molecular aggregates such as supramolecular chemical micelles and vesicles, the formulation, which based on the hydroxypropyl-beta-cyclodextrin and phospholipid, is prepared under the condition of hyperthermia sterilization and decompression. The plurality of external terminals of the piezoelectric package and the plurality of connecting terminals of the circuit component package are electrically connected by metal bonding. The analytical tool is configured to generate a solid body representing the internal cavity and calculate a volume of the solid body. The bag is further designed and configured to enable the establishment of the bag in an open position by pressure exerted by hands inserted through the top opening, and to conveniently allow the addition of fresh litter through the top opening.
