The active/passive Q-switching operation of a 2 [tm a-cut Tm,Ho：YAP laser was experimentally demonstrated with an acousto-optical Q-switch/MoS2 saturable absorber mirror. The active Q-switch laser was operated for the first time, to the best of our knowledge, with an average output power of 12.3 W and a maximum pulse energy of 10.3 mJ. The passive Q-switch laser was also the first acquired with an average output power of 3.3 W and per pulse energy of 23.31 μJ, and the beam quality factors of Mx^2 = 1.06 and My^2 = 1.06 were measured at the average output power of 2 W.

川中地区震旦系灯影组—下寒武统龙王庙组储层内存在明显的热液活动痕迹,焦沥青也表现出热液蚀变的特征,然而很少有研究去探讨热液活动与天然气成藏演化的关系,导致现今对灯影组油气成藏演化史的认识还存在明显不足。然而,热液对灯影组油气成藏的影响不可忽略,要正确认识灯影组天然气的成藏演化过程并识别勘探有利区,还需要对热液裂解气聚集成藏方面进行更深入的研究。基于对焦沥青的充填特征、光学纹理及结构特征的详细研究,结合热液矿物捕获的流体包裹体地球化学的研究方法,探讨了灯影组—龙王庙组储层内焦沥青的成因,分析了热液活动与原油裂解之间的关系。川中地区灯影组—龙王庙组焦沥青形成于热液活动期间,具有与中间相相同的光学各向异性特征。焦沥青可以划分为4种类型:细粒镶嵌型、中粒镶嵌型、粗粒镶嵌型及流线型,其形成温度过300℃,远超地层最大埋深温度,显示出热液成因的特征。热液活动发生于晚二叠世,与峨眉山地幔柱活动相关,热液流体温度超过300℃,导致了灯影组—龙王庙组储层内的原油裂解。研究发现热液活动将灯影组—龙王庙组古油藏内原油裂解的时间提前到了晚二叠世,打破了灯影组—龙王庙组现有的成藏模式,有助于对天然气成藏演化过程的重新认识和聚集有利区的识别。

Based on analysis of field survey, drilling and seismic data, the formation and evolution process of Deyang-Anyue erosion rift trough in Sichuan Basin was reconstructed, and exploration areas were divided and evaluated. The results show that:(1) Dengying Formation in and around Deyang-Anyue erosion rift trough varies widely in sedimentary characteristics. The Dengying Formation in the northern part of the erosion rift trough developed deep-water sediments, the Dengying Formation in the northern part of the basin varied gradually from basin to slope, platform margin, and restricted platform, and the Dengying Formation in the middle and southern parts of the trough developed carbonate platform facies.(2) Deyang-Anyue erosion rift trough is formed by extensional rift and karst erosion jointly, the north section of the erosion rift trough is mainly the product of tensile rift, while the middle and south sections are formed by erosion in multi-episodes of Tongwan period.(3) Based on the segmented origins of the erosion rift trough, Dengying Formation in and around it is divided into three exploration fields: lithologic mound and beach bodies at the northern platform margin of the basin, karst mound and beach bodies in the central platform, and karst residual mounds in the central southern trough of the basin, among them, the karst residual mounds in the central southern trough of the basin are a new frontier for natural gas exploration in the basin, and the lithologic mound and beach bodies at the northern platform margin are a new position for increasing the reserves of trillions of cubic meters of natural gas resources in the basin.

Healthy soils are vital for the diverse services provided by ecosystems to human society~[1], such as provisioning(food,fiber, timber, and fuel), regulation(climate, disease, and natural hazards), waste treatment, nutrient cycling, and cultural services. Soil has a three phase system and the interactions between soil chemical, biological, and physical attributes determine functions(hydraulic, thermal, and gas fluxes).

A series of nucleotide sugar interconversion enzymes(NSEs) generate the activated sugar donors required for biosynthesis of cell wall matrix polysaccharides and glycoproteins. UDPglucose 4-epimerases(UGEs) are NSEs that function in the interconversion of UDP-glucose(UDP-Glc) and UDP-galactose(UDP-Gal). The roles of UDP-glucose 4-epimerases in monocots remain unclear due to redundancy in the pathways. Here, we report a brittle plant(bp1) rice mutant that exhibits brittle leaves and culms at all growth stages. The mutant culms had reduced levels of rhamnogalacturonan I, homogalacturonan, and arabinogalactan ***, the mutant had altered contents of uronic acids, neutral noncellulosic monosaccharides, and cellulose. Map-based cloning demonstrated that OsBP1 encodes a UDPglucose 4-epimerase(OsUGE2), a cytosolic protein. We also show that BP1 can form homoand hetero-protein complexes with other UGE family members and with UDP-galactose transporters 2(OsUGT2) and 3(OsUGT3), which may facilitate the channeling of Gal to polysaccharides and proteoglycans. Our results demonstrate that BP1 participates in regulating the sugar composition and structure of rice cell walls.

This paper presents a continuous method for solving binary quadratic programming problems. First, the original problem is converted into an equivalent continuous optimization problem by using NCP (Nonlinear Complementarity Problem) function, which can be further carry on the smoothing processing by aggregate function. Therefore, the original combinatorial optimization problem could be transformed into a general differential nonlinear programming problem, which can be solved by mature optimization technique. Through some numerical experiments, the applicability, robustness, and solution quality of the approach are proved, which could be applied to large scale problems.
