In this paper a finite-difference time-domain method is used to model and analyze the application of dynamic scanning in target detection and imaging by using an effective negative-refraction photonic crystal(NR-PC) flat *** results show that there is a transmission peak,with a value far greater than unity,resulting from the influence of mini-forbidden bands and resonance excitation effect at a resonance frequency of 0.3068(a/λ).Thus,the lightwave emitted from the point source will provide strong backscattered waves after being focused on the target by the NR-PC lens that greatly improves the refocusing resolution and imaging resolution of the backscattered ***,a comparison with a non-dynamic scanning scheme clearly demonstrates that the dynamic scanning scheme provides improved refocusing *** conclusion,our investigation optimized the performance of a detection and imaging system,and provided the basis for converting an idealized LHM lens into a physically realizable NR-PC flat lens.

The gas-phase synthesis of dimethyl carbonate (DMC) from methanol, carbon monoxide and oXygen has here Studied in a flow system at atomspheric Pressure. A series of Catalyst used in this reaCtion have been prepared and evaluated. The influence of trivared carbon supporters, alkaline metal Promoters and operation conditions on DMC opthesis reaction has been discussed. Under the conditions of 130℃, CO/O2=1 .96, SV=3340h-1, the space-time yield (STY) of DMC over PdCl2-CuCl2-CH3COOK/ac. catalyst is 217g/l-cat h,which is higher than what is published in the literatUre so far.

对未置氢及置氢Ti-6Al-4V合金进行了TG/DSC试验,研究了置氢钛合金的除氢行为。结果表明,当温度超过600℃时,置氢钛合金的失重规律与未置氢钛合金具有较大的差别。当加热温度在600-900℃之间时,置氢钛合金的失重随着氢含量的增加而增加。这是由于置氢合金中的亚稳相发生了分解。不考虑合金氧化的影响,置氢钛合金的最大失重与合金中的氢含量一致。置氢钛合金的最佳除氢温度为750℃。对于不同氢含量的置氢钛合金,其除氢工艺是相同的。

Compression tests of the hydrogenated Ti6Al4V0.2H alloy were carried out using an Instron 5569 machine at room temperature. True stress-strain curves of the hydrogenated Ti6Al4V0.2H alloy under different compressive strains were obtained. Microstructure evolution of the hydrogenated Ti6Al4V0.2H alloy during the process of compression was investigated by optical microscopy and transmission electron microscopy. Results show that true stress-true strain curves of Ti6Al4V0.2H alloy have good repeatability. The deformation of grains, the dislocation density and slipping evolution during the process of compression are discussed.

四川盆地是一个大型富含天然气盆地,已发现常规和非常规两大类油气资源,油气产层多,资源丰富,但盆地目前的油气勘探程度仍然较低,油气勘探潜力大,盆地多类型油气藏并存的原因尚不十分清楚。为此,综合研究了烃源岩特征、多类型优质储层的形成条件、古今构造对油气的控制及保存作用,探讨了四川盆地多种类型油气藏并存发育的成因,并提出了该盆地下一步油气勘探方向。研究结果表明:①多套广覆式分布的具有多类型有机质、不同成熟度的烃源岩是四川盆地多类型油气资源并存的基础;②海陆相沉积环境并存、多类型岩溶与裂缝改造、白云石化、火山活动及热液作用等多因素促成多类型优质储层的形成;③古今构造控制了多类型油气的富集和分布;④良好的保存条件是多类型油气资源并存的重要条件。结论认为:①四川盆地是一个超级富气盆地,其中常规天然气还具有较大的勘探潜力,古裂陷边缘及古隆起的周缘是探索大中型气田的重要区带;②3500 m以深的深层/超深层是下一步页岩气勘探的重要领域,下侏罗统湖相页岩是陆相页岩气现实有利勘探层,可与页岩油并行勘探;③川中地区上三叠统须家河组、中侏罗统沙溪庙组是目前致密砂岩气的重要勘探方向;④川中和川北地区的下侏罗统自流井组大安寨段、中侏罗统沙溪庙组是页岩油、致密油的有利勘探区;⑤赤水、江津、潼南等地区的上二叠统龙潭组则是煤层气的有利勘探区。
