Ignition delay of syngas is an important factor that affects stable operation of combustor and adding diluents to syngas can reduce NO_x *** paper used H_2O,CO_2 and N_2 as diluents and calculated ignition delay of syngas in temperature range of 900-1400 K and at pressures of 10 and 30 atm *** high temperature range,comparing with N_2 dilution,adding H_2O and CO_2 can significantly inhibit autoignition of syngas because they have higher collision efficiencies in reaction H + O_2(+ M) = HO_2(+ M).As for low temperature conditions,adding H_2O can increase reactivity of syngas,especially under high pressure,because of its high collision efficiency in reaction H_2O_2(+ M) = 2OH(+ M).Comparing with different dilution rates shows that for syngas and operating conditions in this paper,adding N_2 mainly influences temperature rising process of syngas combustion,thus inhibiting reactivity of *** addition,this paper calculated ignition delay of syngas at different equivalence ratios(φ= 0.5,1.0).Higher equivalence ratio(φ≤1) means that less air(especially N_2) needs to be heated,thus promoting ignition of syngas,

In order to estimate the systematic error in the processof maneuvering target adaptive tracking, a new method is *** proposed method is a linear tracking scheme basedon a modified input estimation approach. A special augmentationin the state space model is considered, in which both the systematicerror and the unknown input vector are attached to thestate vector. Then, an augmented state model and a measurementmodel are established in the case of systematic error, andthe corresponding filter formulas are also given. In the proposedscheme, the original state, the acceleration and the systematicerror vector can be estimated simultaneously. This method can notonly solve the maneuvering target adaptive tracking problem in thecase of systematic error, but also give the system error value inreal time. Simulation results show that the proposed tracking algorithmoperates in both the non-maneuvering and the maneuveringmodes, and the original state, the acceleration and the systematicerror vector can be estimated simultaneously.

A Multi-component Matrix Loop Algebra and Its Application

引用

Communications in Theoretical Physics 2005年第6X期44卷 997-1001页

作者： dong Huan-he ZHANG Ning Information School Shandong University of Science and Technology Qingdao 266510 China

A set of multi-component matrix Lie algebra is constructed. It follows that a type of new loop algebra AM-1 is presented. An isospectral problem is established. Integrable multi-component hierarchy is obtained by Tu pattern, which possesses tri-Hamiltonian structures. Furthermore, it can be reduced to the well-known AKNS hierarchy and BPT hierarchy. Therefore, the major result of this paper can be regarded as a unified expression integrable model of the AKNS hierarchy and the BPT hierarchy.

Redshift drift constraints on holographic dark energy

引用

Science China(Physics,Mechanics & Astronomy) 2017年第3期60卷 80-86页

作者： dong-Ze he Jing-Fei Zhang Xin Zhang Department of Physics College of Sciences Northeastern University Center for High Energy Physics Peking University

The Sandage-Loeb （SL） test is a promising method for probing dark energy because it measures the redshift drift in the spectra of Lyman-o： forest of distant quasars, covering the ＂redshift desert＂ of 2 ≤ z ≤ 5, which is not covered by existing cosmological observations. Therefore, it could provide an important supplement to current cosmological observations. In this paper, we explore the impact of SL test on the precision of cosmological constraints for two typical holographic dark energy models, i.e., the original holographic dark energy （HDE） model and the Ricci holographic dark energy （RDE） model. To avoid data inconsistency, we use the best-fit models based on current combined observational data as the fiducial models to simulate 30 mock SL test data. The results show that SL test can effectively break the existing strong degeneracy between the present-day matter density Ωm0 and the Hubble constant 1-1o in other cosmological observations. For the considered two typical dark energy models, not only can a 30-year observation of SL test improve the constraint precision of Ωm0 and h dramatically, but can also enhance the constraint precision of the model parameters c and α significantly.

作者： Teng Li he dong Can Zhang Ran Mo State Key Laboratory of Natural Medicines Jiangsu Key Laboratory of Drug Discovery for Metabolic Diseases Center of AdvancedPharmaceuticals and 8iomaterials China Pharmaceutical University Nanjing 210009 China

Spurred by numerous achievements in nanoscience and nanotechnology, the evolution of nanoparticulate drug delivery systems （nano-DDSs） is in its rapid growth period and attracting considerable attention due to their unique advantages in biomedical applications. Natural particulates ranging from mammalian cells to bacteria possess their own distinctive delivery processes and mechanisms, which inspires more design and development of cell-based DDSs by integrating the innate functions of cells with the nanoscale characteristics of nanoparticles. In this review article, we focus on the recent advances in cell-based DDSs for site-specific delivery of therapeutics and enhanced treatment of diseases. The promise and perils of cell-based DDSs are also discussed.
