Photo-curing hydrogel for multi-cell sorting and stem cell area-selecting differentiation and preparation method thereof

The invention belongs to the field of biomedical materials, and particularly relates to photo-curing hydrogel for multi-cell sorting and stem cell area-selecting differentiation and a preparation method thereof. The photo-curing hydrogel is prepared by taking modified high-polymer materials with the photo-curing performance as raw materials and are divided into multiple different areas by straight-stripe-shaped or net-stripe-shaped or annular-stripe-shaped micro-pattern structures, the hardness of the photo-curing hydrogel in the same area is same, the hardness of the photo-curing hydrogel in the different areas is same or different, and the overall photo-curing hydrogel at least has two kinds of the hardness. According to the photo-curing hydrogel for multi-cell sorting and stem cell area-selecting differentiation and the preparation method thereof, on one hand, the elasticity moduli of all the areas of the photo-curing hydrogel are different by controlling the ultraviolet radiation curing degree; on the other hand, all the areas with the different elasticity moduli present the micro-pattern structures on the photo-curing hydrogel, selective adhesion, proliferation and differentiation of cells on the photo-curing hydrogel can be achieved by combining the elasticity moduli with the micro-pattern structures, and therefore controllable cell sorting or stem cell area-selecting differentiation can be achieved.

Method for adaptively setting set value of protection device

The invention relates to the technical field of power system automation, in particular to a method for adaptively setting the set value of a protection device. When a power grid operates normally, theprotection device operates in an inspection process, whether a power system has a fault or not is judged according to an electrical quantity collected in real time, and the electrical quantity set value of a splitting device is calculated and updated in real time; if the electrical quantity is stable and does not exceed a set range, the protection device continues operating in the inspection process; if the electrical quantity exceeds the set range, a fault handling process is started, the electrical quantity sampled in real time is only used for fault judgment, and the electrical quantity set value of the splitting device is not updated any more. Thus, the protection set value of the small-hydropower-station splitting protection device can be updated in real time, the protection settingvalue is calculated in real time, and the method can adapt to set values under changing of different power grid operation modes and seasons, relieve the workload of relay protection and maintenance and debugging personnel and improve the accurate action rate of the small-hydropower-station splitting device, thereby ensuring safe and stable operation and reliable power supply of the power grid.
