This study aimed to investigate patient dose in diagnostic screen-film radiographic examinations in the city of Lhasa, China. Seven out of the twenty-six hospitals registered with the Lhasa Health Bureau were included in the investigation. The entrance surface air Kerma (ESAK) of seven conventional screen-film radiology X-ray equipment in these hospitals was measured with a QA dosimeter in September 2012. The X-ray examinations were divided into three categories: PA (posterior-anterior) chest, upper/lower limb, and AP (anterior-posterior) lumbar spine. For each category, ESAKs were calculated and analyzed. The mean ESAK was 0.6 mGy for PA chest, 0.3 mGy for upper/lower limb, and 1.8 mGy for AP lumbar spine. In addition, the mean ESAK value recorded for PA chest X-ray examinations exceeded the corresponding value recommended by the International Atomic Energy Agency (0.4 mGy).

Based on fire growth probability and burned area, the method for evaluating burned area in building fire is presented in this paper. According to fire dynamics and different characteristics in fire growth process, the process is divided into four phases. By means of probability theory and event tree analysis, fire growth probability and critical time of every phase are calculated. Average burned area of building can be evaluated.

Statistics and countermeasures of non point source pollution in plain river network of Taihu Basin

Strategic Study of CAE 2010, Volume 12, Issue 6, Pages 113-116
Comparing the total pollution load into rivers in 2005 with the one in 2000, the analysis suggests that the percentage of point sources in total kept reducing year by year, and the non-point sources increased significantly, especially total phosphorus (TP) whose amount of pollution from non-point sources have already exceeded that from point sources. The total amount of pollution from non-point sources was almost equal, but its composition changed. The pollution from rural domestic sewage ranks first and the pollution from aquaculture and fields ranks second in the total amount of pollution from non-point sources. Based on the analysis of causes of non-point sources pollution, this essay gives some suggestion on the control of non-point sources pollution in plain river network of Taihu Basin.

Shawan exploration of Juggar Basin was faced with exploration problems of small scale oil sand, thin reservoir and rapid changes in lithology. In 2005, Pai 2 Well in Shawan formation drilled oil layer. It obtains 49.6 t/d industrial oil and the ground oil viscosity is 1.6 mPa·s. Practice and boldly exploiting contributes to Shawan's breakthrough of shallow, light oil and high lithologic oil reservoir, and high precision three dimensional seismic technology has played a crucial role. Chepaizi region of Shawan formation has double gathered and the "three floors" oil and gas accumulation mode of multiple oil source transporting, multi line oil, multi type enrichment and multi-grade coexistence characteristics. Shawan's light oil sand body shape has a good corresponding relationship with amplitude property, and the oil water boundary can be identified by seismic attributes. Oil of thin oil is oil lower limit, and powder and fine sandstone is lithologic lower limit, permeability of 0.022 μm2 and porosity of 20 % is lower limit for the properties. Reservoir interval transit time is greater than 300 μs/m, resistivity is greater than 1.5 Ω·m and resistivity index is greater than 5.5. 23 reservoirs have been found in Shawan.

Important Progress in Estimating Forest Resources

Traditional forest resources inventory is a hard mission, which needs much time, work and money. At the end of 1970s, remote sensing technology was introduced into China and has been used since then in the activities of forest resource inventory, especially in estimating forest stock volume, they include: Estimating volume stock of forest using quantitative value and qualitative factors of satellite data; Application of above — mentioned techniquess in different climate zones in China (The method has been spreaded over 7 million hectares in China); Estimating forestland, including area of fragments woodland and index of forest network etc. Through careful analysis of precision against costs, it is indicated that remote sensing method can save 1/3 to 1/2 budget in comparison with the traditional method.
In recent years, based on the previous study and by using modern statistic measure, new exploration and deeper study were done. These studies have solved some key problems in application of remote sensing in forestry resource inventory, such as calibrating remote sensing image against sampling plots on the ground, decreasing field work, increasing accuracy of stock volume on compartment, fast selecting optimal function, and avoiding factors that are hard to be determined by remote sensing data (such as age group, crown canopy, etc.). Both theor etical and practical applications have confirmed that remote sensing information play a leading role in estimating forest stock volume.
These discussed studies have made a good basis for the application of remote sensing in forest inventory, and given strong support for establishing a new system of forest inventory, which use remote sensing technology as primary measure.
At the end of this paper, a frame of new system of forest resource inventory is put forward, and suggestion on key problem in the new system is discussed.
