Objective: To describe the time point prevalence and distribution of all types of mental disorders in Hebei Province. Methods: From October 2004 to March 2005, stratified multi-stage cluster randomization was used to identify 24,000 subjects >= 18 years of age in Hebei Province. An expanded version of the General Health Questionnaire (GHQ-12) was used to identify subgroups of subjects at high, moderate and low risk of having a mental disorder, then psychiatrists determined their diagnoses by administering a structured psychiatric examination (SCID) that employs Diagnostic and Statistical Manual of Mental Disorder (DSMIV). Results: (1) Twenty thousand seven hundred and sixteen subjects completed the screening. The overall time point rate ofmental disorders was 16.24% (95% CI = 15.8-16.7%). Major depressive disorder (2.70%), unspecified anxiety disorders (2.51%) and dysthymic disorders (2.31%) occupied the preceding positions. The overall life-time prevalence of mental disorders was 18.51% (95% CI = 18.0-19.0%). Major depressive disorder (4.75%), alcohol dependence and abuse disorders (3.86%) and unspecified depressive disorder (2.55%) occupied the preceding positions. (2) The time point prevalence: the overall prevalence ofmental disorders was higher in rural (16.65%) than in urban areas (14.43%) and obviously higher in women (16.79%) than in men (15.70%), P < 0.05-0.01. Accompanied with the age growth, the prevalence goes up. Among the total, 30-49 was 137.17-156.71%, >= 50 was 20.14-28.54%. Conclusions: Through the investigation, we have kept abreast of the time point prevalence and the characteristic of distribution of all types of mental disorders in Hebei Province, and provide scientific basis for the prevention and treatment of mental disorders.

Expressway economic parts is a special form of which correlate expressway regional economy and space structure of town. That is an organism in which economic activity as core and traffic line as tache, multi-district, multi-industry and economic department intergrowth and concomitant. Traffic economic parts is an economic system with dimensional dissipation structure, is a mature social economic organism, its evolving rule has knowability, possibility of macroscopic readjustment and control and reality. This paper offers theoretical gist for exploring road network distribution theory and method based on region spatial structure of town by studying the spatial assembly and diffusion effect of expressway economic parts and discussing the problem of regional road web distributing configuration.

The influence of heat-treated temperature and the CeO2 content on the chemical composition and the valence state of elements on surface of ZrO2-CeO2 thin films deposited on metal substrates has been studied by X-ray photoelectron spectroscopy. Results show that: elements of Fe, Cr, Zr, Ce exist in the form of their respective stable state, such as Fe2O3, (Fe0.6,Cr0.4)O3, ZrO2, CeO2, when heat treated at 600°C and 700°C for 2h respectively;with the increase of heat-treated temperature, the area of oxygen with O1s, peak corresponding to value of bonding energy 529,28ev increases, but the area of oxygen with 01s peak corresponding to value of bonding energy 531.7ev decreases.

X-ray diffraction (XRD) method to measure the residual stress existing in the metal substrate surface layer was introduced and the sol-gel ZrO 2-CeO2 thin film was successfully prepared on SUS304 stainless steel substrate by dip-coating process. The macro residual stress existing in metal substrate was analyzed by XRD. It turns out that the compressive stress existing in the metal substrate surface layer increases with the increase of heat-treated temperature. Based on the above study, colored stainless steels of high quality were prepared by sol-gel process.
