An westward slant ridge over the region ranging from the middle of Huanghe River to North China and East China (30 45°N,105 120°E) is presented,and the ridge effect on the precipitation in Tianjing and in North China is analysed.
After technology revamping,the annual output of Φ210～310 mm round billet at Tianjing Pipe increased up to(900 000) t from(600 000) t and the comprehensive qualified rate of casting billet increased up to 99.66%.
Before the Tangshan earthquake, magnitude 7.8 on July 28, 1976, nine of the fourteen resistivity stations located within the region of Peking, Tientsin and Tangshan recorded gradual decreases in apparent electrical resistivity for a period of 2-3 years.
This article introduces the application of FMCS system in the CTS industry workshop in Tientsin mainly from three aspects: PLC control, DCS system and OPC technique.
In order to investigate the association of vitamin D receptor (VDR) gene polymorphism with Graves′ disease, VDR-Bsm1, VDR-Apa1 genotypes were determined by PCR-RFLP in 102 healthy persons and 120 GD patients in Tianjin area.
In this paper, the focal parameters of 125 earthquakes with M_L≤3.0 during the period from January 1985 to September 1990 in the Tianjin area are calculated;
samples of surface soil were collected from the Tianjin area to study the contamination of DDT and its metabolites. For all samples, p,p′ DDE, p,p′ DDD, p,p′ DDT, o,p′ DDE, o,p′ DDD and o,p′ DDT were analyzed.
The paper introduces the network arrangrment way and access method of C&C08 STP accessed Tianjin area telephone networks network Management System and the problems for attention et al.
This pest mainly distributed in partial Asian countries (China, Japan, Korea, Mongolia) and Far East Russia, while in China it presented in Heilongjiang, Jilin, Liaoning, Shandong, Inner Mongolia, Hebei, Taiwan Provinces and Tianjin City, etc.
Consequently, the assessment not only presented the threatened status of Hebei flora but also indicated the relatively fragile health status of the environment of Beijing and Tianjin.
In addition, more concrete measures are needed to conserve the plant diversity and the natural ecosystem of Hebei Province and even the whole region encompassing Beijing and Tianjin.
At the end of the present work, a set of actual aerial photographs, at the image scale of 1∶34 000, with airborne GPS data taken from Tianjing site, China were processed by WuCAPS.
As an example, we calculated the chaotic attractor of the precursory field evolution and the fractal dimension of the precursory time and space distribution and its change tendencies before large earthquakes in Beijing-Tianjing area.
The commonly used acupoints, are Quchi (LI 11), Jianyu (LI 15), Tianjing, (TE 10), etc, which are around joints, on the upper body, on, the lateral aspect or on the ends of the limbs.
A systematic analysis and processing of the relation between the fault deformation network in the Beijing-Tianjin area and earthquakes by part of the principle and method of system science (Information theory) is reported in this paper.
The result of the study indicates that the fault deformation network related to the fault loading to the earthquake in the Beijing-Tianjin area, exhibited obvious features of colony anomalies before the Tangshan earthquake of 1976.
Long-range transport and site contamination of PAHs might not be key contributors in forming the distribution pattern of PAHs in the topsoil of Tianjin area.
