An approach of solving excitonic absorption is presented for an asymmetric double quantum well driven by an intense terahertz field embedded in a semiconductor microcavity.The formalism relies on Zubarev’s Green functions,which allow us to handle the microcavity field and terahertz field as the photons and to fully account for the quantum aspect of the optical response of the asymmetric double quantum wells.Rich nonlinear dynamics behaviors of the replica peak and the Autler-Townes splitting are systematically studied in undoped asymmetric double quantum wells for taking account of the multiple factors,such as the detuning,coupling constant of the intense terahertz field,decay rate of the second electron subband,photon number of the intense terahertz field.The work provides a simple and convenient approach to deal with the microcavity-optical response of the asymmetric double quantum well in a fully quantum mechanical framework.

Aiming at the mobility of the nodes in wireless sensor network,a cluster-based group key management scheme for mobile nodes in wireless sensor networks is put forward based on the Chinese Remainder Theorem and Elliptic Curve Cryptosystem.Using the idea of grouping within cluster,the group key management was divided into two levels:the first level being the management of the cluster head and group leaders within the cluster,and the secondary being the management of group leader and its members.The former,by using the Chinese Remainder Theorem,transferred the amount of calculation to the base station,and saved the storage cost at the same time.The latter,by using elliptic curve cryptosystem,produced group keys,and each group shares different group keys.The cluster head was used to check the joining mobile node’s historic updating information,compute digital signature verification,and assigned it to the open group after authentication.Analysis results showed that the scheme meeted sensor node’s need for low storage and low energy consumption,and the use of elliptic curve cryptosystem increased the network’s security,making it more suitable for nodes’ resource-constrained and vulnerable wireless sensor networks.

From the angle of engine combustion performance,the influence of the alternative fuel on combustion performance after the aeroengine changed into floor combustion gas turbine was researched.FLUENT,fluid computing software,was used to compute different alternative fuels on the combustion properties.For the floor combustion gas turbine combustor in the burning of aviation kerosene,light diesel oil,industrial fuel alcohol and natural gas,simulation was carried out,and the engine combustion performance of different fuels was given.The result showed that,from the angle of engine combustion performance,there was no difference between aviation kerosene and light diesel oil,which can be used directly or combined with aviation kerosene by engine combustor.The emission of NOx and CO from natural gas combustion was 1 000;natural gas is an ided low-emission fuel.There was a wide gulf between the aviation kerosene and the industrial fuel alcohol,which needs an in-depth study for the technology on changing fuel from aviation kerosene to industrial fuel alcohol after the aeroengine changed into floor combustion gas turbine.The research has a valuable reference for the development of the next generation of aviation alternative fuel.

Based on the construction of a sewer pipeline built perpendicularly above a existing shield tunnel in Hangzhou,the pipe jacking construction procedure was simulated by software FLAC3D,and verified reasonable after comparing the simulation results with the measured results.By changing the pipe diameter,pipe material and surrounding soil’s characteristic of the shield tunnel,its displacement rule of existing shield tunnel was analyzed.The studies showed that the max vertical and horizontal displacement of the shield tunnel happened under the sewer pipeline,and the further away from the pipe jacking line,the smaller the deformation;the more diameter of sewer pipeline’s pipe,the more displacements of existing shield tunnel,and the influence of the sewer pipe diameter on vertical displacement was significantly greater than the horizontal displacement;the less elastic modulus of sewer pipe,the more displacements of the shield tunnel;the more elastic modulus of the soil layer,the less displacements of the shield tunnel.

Considering the interaction of frame structure,raft foundation and ground base by using the numerical simulation method of ANSYS procedure and the condition of the stationary balance of the linked point between frame structure,raft foundation and the distortion harmony condition,the method of the interaction of frame structure,raft foundation and subsoil was formed.And comparson with the conventional design of frame structure in column internal force and column bending moment was made.Results show that when considering the interaction,the raft foundation deformed “basin shape”,and frame structure stress was re-distributed.Angle axial force increased,and the side column and the column axial force decreased,and the moment also significantly increased.Settlement of rafts of different thickness was different;with the increase of thickness,the maximal settlement became smaller.

PsbA-trnH,RbcL and trnL-F fragments were amplified from the three wild grapes in Xiangxi Autonomous Prefecture by PCR,and cloned into pMD18-T vector for sequencing.Based on PsbA-trnH,RbcL and trnL-F gene sequences,the phylogenetic trees between these three wild grapes and other related Vitaceae plants were constructed by software Mega4 for analyzing their phylogenetic relationship.The results showed that all of these three cpDNA fragments could be used as molecular markers in phylogenetic analysis among genera of Vitaceae,but of which results had a little difference from that of traditional morphological methods.Furthermore,RbcL gene fragment could be used for molecular identification among Vitis species.
