摘要：
The dynamic behavior of a chemical sensor can be studied in both the spatial and temporal domains. The spatial domains can be studied by studying plume behavior and method of gas-distribution measurement. Governed by the fluid dynamics, the plume behavior is solved using the Navier-Stokes equation. It was showed that the study of spatial domain can realize the measurement of the gas distribution using a homogeneous sensor array. Two types of sensor arrays such as sparse and packed sensor arrays, are available. The global behavior of the plume can be revealed by the sparse sensor array whereas the packed one reveals the local detailed behavior of the plume while the optical method is useful to obtain the plume image.
