Abstract: The present invention provides a polypeptide derivative, or a modified derivative or salt thereof, and use of the polypeptide derivative, or the modified derivative or salt thereof. The polypeptide derivative, or the modified derivative or salt thereof comprises a polypeptide having the sequence of the following general formula I: general formula I: HX2QGTFTSDX10SKYLX15EX17X18AX20X21FX23AWLEX28X29X30, wherein the definitions of X2, X10, X15, X17, X18, X20, X21, X23, X28, X29, and X30 are consistent with those in the claims and description. The polypeptide derivatives of the present invention are dual agonists for GC/GLP-1 receptor, have a synergic effect on energy metabolism, can effectively reduce weight and improve a body fat level while reducing blood glucose, and have a potential application value in the field of treatment of metabolic diseases such as diabetes and obesity.

Abstract: A method is disclosed for detecting power interruption duration of an electronic device. The method can include establishing a curve model of linearly synthesized values of temperature sensor readings versus time; after power-on, acquiring each of the initial temperature values by respective temperature sensors mounted on the electronic device, and transmitting the temperature initial values to a microprocessor; calculating a linearly synthesized value of the temperature sensor readings of the electronic device according to a power-on duration for this time and a stored curve model, and storing the linearly synthesized value of the temperature sensor readings as a basis for calculating the power interruption duration thereafter. When the electronic device is powered on again after power interruption, a linearly synthesized value of the temperature sensor readings according to the power-on time for this time can be calculated, and used for calculating the power interruption duration thereafter.
