A metal-resin composite, a surface treatment method, and a substrate of a printed circuit board (PCB) for high-frequency and high-speed signal transmission comprise a surface-treated metal, and the surface-treated metal includes a nano-scale pore array that is used for filling of a resin and vertically extends from a surface to an interior of a metal, where nano-scale pillars are provided to extend from bottoms to openings of nano-scale pores of the nano-scale pore array. The pillar-in-pore structure makes a resin entering a nano-scale pore have an ultra-high anchoring effect on a resin body outside the nano-scale pore. Therefore, on the premise of not using an additive such as a T liquid or a coupling agent, the present disclosure greatly improves a tensile bonding strength at an interface between a resin body and a metal substrate, and also eliminates a decline in an interfacial bonding strength of a composite.

A cooling-heating stage-type fast scanning calorimeter capable of being integrated with other microscopic structure characterization techniques. The cooling-heating stage-type fast scanning calorimeter includes a sample chamber provided with light transmission and reflection transparent windows on the walls thereof, a cooling-heating stage provided with internal heating elements and coolant channels for temperature control and also provided with a transmission hole, a sample chamber temperature control system and a fast calorimetric system. The cooling-heating stage-type fast scanning calorimeter has the advantages that the fast calorimetric system with heating/cooling rates is miniaturized into the cooling-heating stage, and reflection and transmission windows as well as the transmission hole of the cooling-heating stage are used for in-situ integration of calorimetry and microscopic structure characterization; and through program-controlled rapid response, dynamic compensation of sample temperature disturbances caused by incident light in structure measurement is achieved, and sample temperature is stabilized, thus facilitating precise isothermal research.
