The invention discloses a method for simultaneously measuring double-domain induced polarization full parameters. A time domain method is adopted to record and display a potential difference and a curve formed by a cycle repeated signal sent by a power supply electrode between measuring electrodes; synchronization of transmission and receiving of signals are automatically achieved by mathematical treatment; and by calculation, the real part and the imaginary part of a fundamental wave and a harmonic wave are solved according to the obtained synchronized potential difference and curve so as to further calculate apparent resistivity, apparent absolute phase position, apparent amplitude diffusivity and view diffusivity. When the apparent resistivity and the apparent absolute phase position are measured, apparent polarization rate, an apparent charging rate and an attenuation curve are calculated according to a charging curve or a discharging curve at the same time. A time domain (interrupted rectangular wave) power supply mode can be independently adopted and a frequency domain (continuous rectangular wave) power supply mode can also be independently adopted so as to realize the purpose of simultaneously measuring the double-domain induced polarization full parameters in one-time power supply. According to the method, the technical problem of providing more information which can reflect polarization body characteristics and correlated information in short one-time measurement time can be solved.

The invention discloses a selection method of observer nodes in a wireless sensor network. The selection method comprises the following steps: cluster-head nodes start selection negotiation of the observer nodes; cluster member nodes predict observation quality increment after participating in observation; the cluster member nodes judge whether the observation quality increment is more than zero after participating in observation, if no, the cluster member nodes are in an idle state; if yes, the cluster member nodes calculate cost values of participating in observation, and send the cost values to the cluster-head nodes; the cluster-head nodes add a node which has the minimum observation cost value and selected from the cost values received from the cluster member nodes to an observer node set; the cluster-head checks whether the existing observer node set meets the observation quality requirements, if yes, the cluster-head completes the selection negotiation process of the observer nodes in a cluster; if no, the cluster-head returns to start the next selection. The selection method of observer nodes in a wireless sensor network can reduce energy consumption of the network on the premise of meeting the data quality requirements of users.
