摘要:
An information recording medium including a substrate, an intermediate conductive layer, and a high molecular weight layer. When the high molecular weight layer is heated to close to its glass (transition) temperature by applying an AC field in order to induce thermal motion in molecular electric coupling poles present in the high molecular weight layer, the coupling poles are polarized by an external electric field applied between a microscopic probe tip and the intermediate conductive layer, the polarization becoming fixed when the temperature of the layer drops.
摘要:
A liquid testing system is provided, which includes a distribution module, a testing chip, a driving module and an image analyzing module. The distribution module is for providing a liquid. The testing chip receives the liquid from the distribution module. The driving module is connected to the testing chip and drives the testing chip to rotate, wherein the liquid flowing in the testing chip is actuated by centrifugal force. The image analyzing module produces and analyzes an image of the liquid in the testing chip.
