| 1 | Soil Enzyme Activity Changes in Different-Aged Spruce Forests of the Eastern Qinghai-Tibetan Plateau显示文摘Activities of selected soil enzymes (invertase, acid phosphatase, proteinase, catalase, peroxidase and polyphenoloxidase) were determined under different spruce forests with restoration histories of 5, 13, 18, 23, 27 years and an old growth forest over 400 years old in the eastern Qinghai-Tibetan Plateau, China, and their possible use as indicators of ecosystems health were analyzed. Plots 10 × 10 m with 4 replications were established to investigate three hypotheses: soil enzyme activities a) would increase with the restoration process; b) would be greater in surface soils than at lower depths; and c)would be correlated to selected physicochemical properties. Results showed that as the forests developed after restoration,invertase and peroxidase activities usually increased up to the 23 year point. Also soil enzyme activities were associated with surface soils and decreased with depths, suggesting that in earlier restoration stages surface addition of organic fertilizer to soils might be more effective than additions at depth. In the 0-20 cm soil, there were significant correlations (P < 0.01 or < 0.05) between some soil enzyme activities and some selected chemical properties. Therefore, temporal changes in enzyme activities should be included as an indicator when evaluating sustainable forest management practices. | ZHANGYong-Mei ZHOUGuo-Yi WUNing BAOWei-Kai | 2004 | Pedosphere2004，14，3： | 46 |
| 2 | Soil N Pools and Transformation Rates Under Different Land Uses in a Subalpine Forest-Grassland Ecotone显示文摘Soil nitrogen pools (NP), denitrification (DN), gross nitrification (GN), N2O and CO2 flux rates with their responses to temperature increases were determined under five different land uses and managements in a subalpine forest-grassland ecotone of the eastern Tibetan Plateau. Land uses consisted of 1) sparse woodland, 2) shrub-land, 3) natural pasture, 4)fenced pasture, and 5) tilled pasture mimicking a gradient degenerating ecosystem under grazing impacts. The NO3--N content was higher than the NH4+-N content. Comparing tilled pasture with fenced pasture showed that higher intensive management (tillage) led to a significant decrease of soil organic matter (SOM) (P < 0.05) in the soils, which was in contrast to the significant increases (P <0.05) of DN, GN, N2O and CO2 flux rates. GN (excluding tilled pasture) and CO2 flux rates increased with a temperature rise, but DN and N2O flux rates normally reached their maximum values at 12-14 ℃ with tilled pasture (the highest management intensity) being very sensitive to temperature increases. There was a difference between net nitrification and GN, with GN being a betterindicator of soil nitrification. | SUNGeng WUNing LUOPeng | 2005 | Pedosphere2005，15，1： | 19 |
| 3 | Specific cellular immune responses in mice immunized with DNA,adeno-associated virus and adenoviral vaccines of Epstein-Barr virus-LMP2 alone or in combination显示文摘Cellular immune responses,particularly those associated with CD3+CD8+ cytotoxic T lymphocytes (CTL),are critical factors in controlling viral infection.Nasopharyngeal carcinoma (NPC) is closely associated with persistent Epstein-Barr virus (EBV) infection.NPC vaccine studies have focused on enhancing specific antiviral CTL responses.In this study,three vaccines capable of expressing the EBV-latent membrane protein 2 (LMP2) (a DNA vector,an adeno-associated virus (AAV) vector,and a replication-defective adenovirus serotype 5 (Ad5) vector) were respectively used to immunize female Balb/c mice (4-6 weeks old) at weeks 0,2 and 4,either alone or in combination.Our results suggest that combined immunization with DNA,AAV,and adenovirus vector vaccines induced specific cellular immunity more effectively than any of these vectors alone or a combination of two of the three,constituting a sound vaccine strategy for the prevention and treatment of NPC. | WANG Zhan YANG SongMei ZHOU Ling DU HaiJun MO WuNing ZENG Yi | 2011 | Science China(Life Sciences)2011，54，3： | 10 |
| 4 | Changes of Soil Enzyme Activities in Different Restoration Ages of Spruce Forests on the Eastern Qinghai-Tibet Plateau显示文摘Six soil enzymes (invertase, acid phosphatase, proteinase, catalase, peroxidase and polyphenoloxidase ) were chosen for investigation under different spruce forests with restoration ages of 4,10,16 years and an old-growth spruce forest over 400 years old in the eastern Qinghai-Tibet Plateau, China. Results showed that the activities of invertase, phosphatase, proteinase, catalase and peroxidase decreased in newly restored forests except for pholyphenoloxidase. With the development of forests after restoration, the activities of invertase, acid phosphadase, proteinase increased gradually. Our study also indicated that the soil enzyme activities were associated with surface soils and decreased with depths. This result suggested that in the earlier restoration stage the application of organic fertilizer may be more effective by surface addition to soils than deep addition. | ZHANGYong-mei BAOWei-kai PANGXue-yong WUNing ZHOUGuo-yi | 2005 | Wuhan University Journal of Natural Sciences2005，10，4： | 3 |

| 8 | Unified Theory of Fundamental Interactions显示文摘Based on local gauge invariance, four different kinds of fundamental interactions in nature are unified in a theory which has SU(3)C( )SU SU(2)L( )U(1)( )s Gravitational Gauge Group gauge symmetry. In this approach,gravitational field, like electromagnetic field, intermediate gauge field, and gluon field, is represented by gauge potential.Four kinds of fundamental interactions are formulated in the similar manner, and therefore can be unified in a direct or semi-direct product group. The model discussed in this paper is a renormalizable quantum model and can be regarded as an extension of the standard model to gravitational interactions, so it can be used to study quantum effects of gravitational interactions. | WUNing | 2003 | Communications in Theoretical Physics2003，39，5： | 1 |
| 9 | Gravitational Shielding Effect in Gauge Theory of Gravity显示文摘In 1992,E.E.Podkletnov and R.Nieminen found that under certain conditions,ceramic superconductor with composite structure reveals weak shielding properties against gravitational force.In classical Newton's theory of gravity and even in Einstein's general theory of gravity,there are no grounds of gravitational shielding effects.But in quantum gauge theory of gravity,the gravitational shielding effects can be explained in a simple and natural way.In quantum gauge theory of gravity,gravitational gauge interactions of complex scalar field can be formulated based on gauge principle.After spontaneous symmetry breaking,if the vacuum of the complex scalar field is not stable and uniform,there will be a mass term of gravitational gauge field.When gravitational gauge field propagates in this unstable vacuum of the complex scalar field,it will decays exponentially,which is the nature of gravitational shielding effects.The mechanism of gravitational shielding effects is studied in this paper,and some main properties of gravitational shielding effects are discussed. | WUNing | 2004 | Communications in Theoretical Physics2004，41，4： | 1 |

| 11 | New Mechanism for Mass Generation of Gauge Field显示文摘A new mechanism for mass generation of gauge field is discussed in this paper. By introducing two sets of gauge fields and making the variations of these two sets of gauge fields compensated each other under local gauge transformations, the mass term of gauge fields is introduced into the Lagrangian without violating the local gauge symmetry of the Lagrangian. This model is a renormalizable quantum model. | WUNing | 2001 | Communications in Theoretical Physics2001，36，2： | 0 |
| 12 | Gravitational Gauge Interactions of Dirac Field显示文摘Gravitational interactions of Dirac field are studied in this paper. Based on gauge principle, quantum gauge theory of gravity, which is perturbatively renormalizable, is formulated in the Minkowski space-time. In quantum gauge theory of gravity, gravity is treated as a kind of fundamental interactions, which is transmitted by gravitational gauge field, and Dirac field couples to gravitational field through gravitational gauge covariant derivative. Based on this theory, we can easily explain gravitational phase effect, which has a/ready been detected by COW experiment. | WUNing | 2004 | Communications in Theoretical Physics2004，41，3： | 0 |

| 16 | Gravitational Gauge Interactions of Scalar Field显示文摘Quantum gauge theory of gravity is formulated based on gauge principle. Because the Lagrangian has strict local gravitational gauge symmetry, gravitational gauge theory is a perturbatively renormalizable quantum theory. Gravitational gauge interactions of scalar field are studied in this paper. In quantum gauge theory of gravity, scalar field minimal couples to gravitational field through gravitational gauge covariant derivative. Comparing the Lagrangian for scalar field in quantum gauge theory of gravity with the corresponding Lagrangian in quantum fields in curved space-time, the definition for metric in curved space-time in geometry picture of gravity can be obtained, which is expressed by gravitational gauge field. In classical level, the Lagrangian and Hamiltonian approaches are also discussed. | WUNing | 2003 | Communications in Theoretical Physics2003，40，4X： | 0 |
| 17 | Covariant Helicity Amplitude Analysis for J/ψ→γPP显示文摘Covariant helicity amplitude analysis for the process of J/ψ →γPP is discussed.Starting from the S- matrix elements of decay process,we deduce the formulae of helicity coupling amplitudes for two-body decay process. These formulae are used to analyze intermediate resonance states in the process of J/ψ decay to γππ,γKK,γηη' etc. | WuNing RUANTu-Nan | 2001 | Communications in Theoretical Physics2001，35，5： | 0 |
| 18 | Cosmological Model Based on Gauge Theory of Gravity显示文摘A cosmological model based on gauge theory of gravity is proposed in this paper. Combining cosmological principle and field equation of gravitational gauge field, dynamical equations of the scale factor R(t) of our universe can be obtained. This set of equations has three different solutions. A prediction of the present model is that, if the energy density of the universe is not zero and the universe is expanding, the universe must be space-flat, the total energy density must be the critical density ρc of the universe. For space-flat case, this model gives the same solution as that of the Friedmann model. In other words, though they have different dynamics of gravitational interactions, general relativity and gauge theory of gravity give the same cosmological model. | WUNing | 2005 | Communications in Theoretical Physics2005，43，5： | 0 |
| 19 | Solution to the Cosmological Constant Problem by Gauge Theory of Gravity显示文摘Based on geometry picture of gravitational gauge theory, the cosmological constant is determined theoreti-cally. The cosmological constant is related to the average energy density of gravitational gauge field. Because the energy density of gravltatlona] gauge field is negative, the cosmological constant is positive, which generates repulasive force on stars to make the expansion rate of the Universe accelerated. A rough estimation of it gives out its magnitude of the order of about 10^52m^-2, which is well consistent with experimental results. | WUNing GermanoResconi ZHENGZhi-Peng XUZhan ZHANGDa-Hua RIJANTu-Nan | 2003 | Communications in Theoretical Physics2003，40，2X： | 0 |
| 20 | Quantum Gauge General Relativity显示文摘Based on gauge principle, a new model on quantum gravity is proposed in the frame work of quantum gauge theory of gravity. The model has local gravitational gauge symmetry, and the field equation of the gravitational gauge field is just the famous Einstein's field equation. Because of this reason, this model is called quantum gauge general relativity, which is the consistent unification of quantum theory and general relativity. The model proposed in this paper is a perturbatively renormalizable quantum gravity, which is one of the most important advantage of the quantum gauge general relativity proposed in this paper. Another important advantage of the quantum gauge general relativity is that it can explain both classical tests of gravity and quantum effects of gravitational interactions, such as gravitational phase effects found in COW experiments and gravitational shielding effects found in Podkletnov experiments. | WUNing | 2004 | Communications in Theoretical Physics2004，42，4X： | 0 |
