Abstract: An electronic device includes a housing, an indicator plate, a circuit board, a shading case, and a guiding light member. The indicator plate is attached to an outside surface of the housing and defines a receiving hole. The circuit board is attached in the housing. The indicator light is electrically connected to the circuit board. The shading case and the circuit board together encircle the first indicator light. An end of the first shading case abuts the housing and defines a first through hole. The guiding light member is attached between the first through hole and the first receiving hole. Light emitted from the indicator light passes through the through hole to be transmitted to the receiving hole through the guiding light member.

Abstract: A solid-phase polymerization method of high-molecular-weight aliphatic polyester conducts the solid-phase polymerization of aliphatic polyester prepolymer under a gas stream containing sulfonic acid catalyst. The method features preparing metal free aliphatic polyester with high molecular weight, good color and luster and perfect thermal stability efficiently. The non-metal-ion aliphatic polyester is not only applicable to common use, but is also suitable as high value-added medical material and packing material which contacts with food directly than other metal-containing polyester.

Abstract: A method for improving frozen fish fillets treated by way of a salt-water immersion process includes the following steps: pretreating raw fish to obtain fish fillets; precooling the fish fillets; stacking the precooled fish fillets to obtain a fish fillet stack; freezing the fish fillet stack by using a salt-water immersion process, and performing power-variable ultrasonic wave treatment; and feeding the fish fillets into a cold storage, and performing freezing storage at minus 18 degrees centigrade. The power-variable ultrasonic wave treatment includes: firstly treating for 5 to 10 min under the power of 800 to 600 W, and then changing the power to 200 to 600 W for treating for 5 to 15 min. The freezing time of fish flesh is shortened, and formed ice crystals are fine and uniform, thereby preventing the damage of the formed ice crystals to cell walls.

Abstract: A method of ice-crystal wall-breaking extraction of the pomelo peel essencial oil, including: first selecting a fresh pomelo, peeling off the outmost oil cell layer with a peeler, and collecting the cortex that is 1.5-2.5 mm thick; slowly freezing the pomelo peel oil cell layer at ?15° C. to ?30° C. to form ice crystal; breaking the pomelo peel ice crystal with a breaker; thawing the broken ice crystal, and then squeezing with a screw squeezer to obtain a squeezed mixed liquid; adding 3-4% by mass of the table salt to the squeezed mixed liquid, and standing to stratify at reduced pressure, thereby obtaining an oil-water mixture; distilling the mixed liquid at reduced pressure, and collecting the distillate to obtain an oil-water mixture that undergoes natural stratification; discarding the water layer, thereby obtaining the pomelo peel essential oil.
