由于油气田数量与储量规模之间具有分形关系 ,本文在对松辽盆地北部已发现气田储量规模 (储量级别 )进行划分的基础上 ,应用分形方法对该区未发现气田的数量和储量进行了预测 ,同时应用截断帕雷托分布模型预测了未发现气田总储量。结果... 详细信息

由于油气田数量与储量规模之间具有分形关系 ,本文在对松辽盆地北部已发现气田储量规模 (储量级别 )进行划分的基础上 ,应用分形方法对该区未发现气田的数量和储量进行了预测 ,同时应用截断帕雷托分布模型预测了未发现气田总储量。结果表明 ,分形方法与截断帕雷托分布模型预测的未发现气田储量大小相吻合 ,验证了分形方法是一种预测油气田储量的可靠方法。最后得出以下主要结论 :油气田数量与储量规模之间具有分形关系 ;分形方法在勘探程度较高的盆地或区带应用效果好 ,而在勘探新区有些难度。

目的应用螺旋CT评价阻塞性睡眠呼吸暂停综合征(OSAS)患者咽壁软组织和上气道狭窄情况及形态特点。方法经多导睡眠监测仪(PSG)诊断的OSAS患者7例均行清醒状态和深睡状态下上气道软腭后区至会厌后区螺旋CT扫描。结果①5例发生完全性阻塞,且阻塞部位均为软腭后区,有2例分别为多部位阻塞;②OSAS患者软腭长度44.28mm±1.16mm(正常长度41.90mm±1.95mm),软腭厚度9.42mm±0.46mm(正常厚度5.84mm±0.24mm);③OSAS患者在清醒及睡眠状态下软腭后区(RP)、舌后区(RG)、会厌后区(EPG)咽后壁厚度均大于正常值。结论螺旋CT对OSAS临床综合诊断及病因研究具有较高的实用价值。

Diabetes has become a major global problem threatening public health,however,no curative medicine is found to reduce the prevalence rate of it,especially the type 1 diabetes(T1D).T1D is a chronic autoimmune disorder mediated mainly by effector T cells(Th1),but the factors inducing clinical disease remain largely *** studies have indicated a positive relationship between T1D and viruses such as Coxsackie B virus and Cytomegalvirus. However,reports on whether Hepatisis B virus(HBV) take roles in T1D are limited and controvercial. Clinical data showed an increasing number of T1D patients in developed countries where with much low incidence of HBV infection,but there are relative few T1D patients in China with nearly 150 million HBV carriers, indicating the potential effect of HBV on *** the contrary,other reports found no correlation between T1D and ***,some studies have implied a protective role of HBV in the initiation or development of T1D,which may be explained by the hygiene hypothesis,although the immune mechanism is still *** order to address the role of HBV in T1D development,we used streptozotocin(STZ) to induce T1D in BALB/c HBV-transgenic(HBV-Tg) *** results suggested that HBV may delay the onset of T1D and may finally reduce the incidence of it.100%of mice in normal BALB/c group were diagnosed as T1D at the end of observation period,comparing with 87.5%of mice in HBV-Tg group(P=0.0106).And the onset of diabetes is also earlier in normal group after five consecutive STZ *** protective role of HBV might be due to the presense of Tregs in HBV-Tg *** studies are necessary to confirm how could these changes be involved in the diabetogenisis.

DESIGN OF XIAOWAN HIGH ARCH DAM

Effects of Air on the Segregation of Particles in a Shaken Granular Bed

水电2006国际研讨会

作者： Zou Lichun Yu Jianqing Yang Hongwen Mu Jin Kunming Hydropower Investigation Design & Research Institute China 115 Renmin Dong road 650051

the Xiaowan arch dam is located in a high seismic area with a height of 292m and a length of about 900m at the crest. It has a high static and dynamic stress level. There is an outstanding characteristic in the design of the Xiaowan arch dam that the advantage of a double-curvature arch dam is fully brought into play to try to reduce the stress level during the construction and normal operation, and when subjected to an earthquake event, firstly under considering the condition of the stability of the abutment supported rock. This characteristic and a special inducing joint placed at the dam heel to reduce or prevent the risk from the opening and the anti-seismic treatments are particularly described.
