A method for prepring a porous aerogel scaffold includes: adding a photoinitiator and polyethylene glycol diacrylate in a buffer solution, dissolving by heating and evenly mixing, adding Pluronic® F127 (Poloxamer 407) into the mixed solution, and standing at a low temperature to obtain an aerogel scaffold material; printing a hydrogel scaffold by using a 3D printing technology, and performing UV irradiation so that a cross-linking of the hydrogel scaffold is caused to form a three-dimensional scaffold with a stable structure, performing low-temperature soaking to remove Pluronic® F127 (Poloxamer 407), and then freeze drying the three-dimensional scaffold to obtain the porous aerogel scaffold. Wherein, Pluronic® F127 (Poloxamer 407) serves as a sacrificial material which is removed after the 3D printing of the hydrogel scaffold is completed, and then a porous structure can be formed in the scaffold in combination with a freeze drying technology, which facilitates the survival, growth and proliferation of cells during the three-dimensional culture.

An alumina-based ceramic tool material with low thermal expansion and a preparation process thereof, accordingly, the ceramic tool material may have both the high hardness of alumina ceramics after the hot pressing sintering, and reduces the thermal expansion coefficient of the overall ceramic material by adding the ScWOas the negative thermal expansion phase, which improves the thermal shock resistance of ceramic tools in high-speed cutting engineering and meets the requirements of large temperature range during the machining of nickel-based superalloys. Moreover, the composite material does not use metal binder and has strong thermal stability even in the high-speed machining under extreme heat-force-chemistry coupling, so it has a high machining compatibility for nickel-based superalloys.

A method for controlling the balanced frosting of outdoor units in a multi-split air-conditioning system solving the problem in existing multi-split air-conditioning systems of resource waste caused by a low utilization efficiency of the heating capability of outdoor units as a result of some of the outdoor units entering a defrosting state when the heating capability is not fully utilized. According to the control method, by determining whether an outdoor unit set satisfies a frosting unbalance condition, the actual output capability of outdoor units of the outdoor unit set is selectively controlled on the basis of the frosting degrees of all the outdoor units. Thus, the difference between the frosting degrees of different outdoor units in the outdoor unit set at the same time can be reduced, such that the heating capability of all the outdoor units can be fully utilized when the outdoor unit set enters a defrosting state.
