The paper describes a new magnetometer with Cs vapor in the spin exchange relaxation free (SERF) regime. Because
cesium atom has a higher saturated vapor pressure than other alkali metallic atoms, so the magnetometer has required
lower operated temperature. We have discussed the effect of different pumping intensities on the polarization and the
pumping rate at 105°C in theory; and the result shows out the magnetometer will have maximum sensitivity when the
pumping intensity is 52mW/cm2. Taking into account all relaxations including collision relaxations, diffusion relaxation
and pumping relaxation from pump light, we find the relaxation rate will be about 6Hz for the cesium magnetometer
with SERF.

In order to improve the efficiency of the information management and the quality of the services of public urban recreational spaces (PURS), the function-based classification are designed and the encoding scheme of the recreation spaces is brought forward on the demand of recreation activities. Shijiazhuang public recreation spaces web service system is constructed based on the three-layer model of Browser/Server (B/S) and can provide excellent services for residents' recreation. Via the Internet explorer, people can browse through the recreational spaces, query for recreation spaces, facilities, recreation function and bus route, and analyze the current service facilities. Build on the residents' recreation requirements, the system offers a way for the public recreation spaces' management, and can improve the quality of the residents' recreation activities.
