To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy.points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the y.ar 2010. By.analy.ing the large angle Bhabha scattering events, we measure the integrated luminosity.of the data sample at each center-of-mass energy.point. The total integrated luminosity.of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty.is statistical and the second sy.tematic.

Plasma enhanced diamond deposition on steel and Si substrates

Diamond growth on Fe-Cr-Al-Si steel and Si substrates was comparatively.investigated in microwave plasma enhanced chemical vapor deposition （MPCVD） reactor with different deposition parameters. Adherent nanocry.talline diamond films were directly.deposited on this steel substrate under a ty.ical deposition condition, whereas microcry.talline diamond films were produced on Si wafer. With increasing CH4 concentration, reaction pressure, or the total gas flow rate, the q.ality.of nanocry.talline diamond films formed on Fe-Cr-Al-Si substrates is gradually.deteriorated in terms of density.and adhesion. This impaired diamond q.ality.on steels is primarily.associated with a combined effect by.the substrate composition and the specific process conditions that favor excessive nucleation of diamond.

Investigation of the crack problem in non-local piezoelectric materials under combined electromechanical loadings

引用

Acta Mechanica Sinica 2009年第2期25卷 219-225页

作者： q. li y. Chen School of Aerospace, Xi’an Jiao-Tong University.710049 Xi’an, China School of Aerospace Xi’an Jiao-Tong University 710049 Xi’an China

The present investigation of the crack problem in piezoelectric materials is performed based on the non-local theory. After some manipulations, the impermeable crack, the permeable crack （the crack gap is full of NaCI solution）, and the semi-permeable crack （the crack gap is full of air or silicon oil） are reduced to a uniform formulation by.assuming the normal electric displacement on the crack surfaces to be an unknown variable. Thus, a triple integral eq.ation with the unknown normal electric displacement is established. By.using the Newton iterative method and solving the triple integral eq.ation, it is found that the normal electric displacement on the crack surfaces is no longer a constant as determined by.previous studies, rather, it depends upon the remote combined electromechanical loadings. Numerical results of the stresses and electric displacement fields show that there are no singularities at the crack tips so that the stresses remain finite. It is of great significance that the concrete electric boundary.condition on the crack surfaces exerts significant influence on the near-tip fields and in this way.play. an important role in evaluating the crack stability.in the non-local piezoelectric materials. More specifically. the impermeable crack model alway. overestimates the finite stresses at the crack tips, whereas the permeable crack model alway. underestimates them.

Journal of Sy.tems Engineering and Electronics 2001年第3期12卷 45-50页

作者： Su, J. Pan, q. Xi, y. Institute of Automation Shanghai Jiaotong University Shanghai 200030 China

A nonlinear visual mapping model is presented to replace the image Jacobian relation for uncalibrated hand/ey. coordination. A new visual tracking controller based on artificial neural network is designed. Simulation results show that this method can drive the static tracking error to zero q.ickly.and keep good robustness and adaptability.at the same time. In addition, the algorithm is very.easy.to be implemented with low computational complexity.

Combining the elastica theory. finite element (FE) analy.is, and a geometrical topological experiment, we studied the mechanical behavior of a ring subjected to multi-pairs of evenly.distributed eq.al radial forces by.looking at its seven distinct states. The results showed that the theoretical predictions of the ring deformation and strain energy.matched the FE results very.well, and that the ring deformations were comparable to the topological experiment. Moreover, no matter whether the ring was compressed or tensioned by.N-pairs of forces, the ring alway. tended to be regular poly.ons with 2N sides as the force increased, and a proper compressive force deformed the ring into exq.isite flower-like patterns. The present study.solves a basic mechanical problem of a ring subjected to lateral forces, which can be useful for study.ng the relevant mechanical behavior of ring structures from the nano- to the macro-scale.

Exploitation of Fenton and Fenton-like reagents as alternative conditioners for alum sludge conditioning

Journal of Environmental Sciences 2009年第1期21卷 101-105页

The use of Fenton＇s reagent （Fe^2＋/H2O2） and Fenton-like reagents containing transition metals of Cu（Ⅱ）, Zn（Ⅱ）, Co（Ⅱ）, and Mn（Ⅱ） for an alum sludge conditioning to improve its dewaterability.was investigated. The results obtained were compared with those obtained from conditioning the same alum sludge using cationic and anionic poly.ers. Experimental results show that Fenton＇s reagent was the best among the Fenton and Fenton-like reagents for the alum sludge conditioning. A considerable effectiveness of capillary.suction time （CST） reduction efficiency.of 47% can be achieved under test conditions of Fe^2＋/H2O2 = 20/125 mg/g DS （dry.solid） and pH 6.0. The observation of floc-like particles after Fenton＇s reagent conditioning of alum sludge suggested that the mechanism of Fenton＇s reagent conditioning was different from that of poly.er conditioning. In spite of the lower efficiency.in the CST reduction of Fenton＇s reagent in alum sludge conditioning compared to that of poly.er conditioning, Fenton＇s reagent offers a more environmentally.safe option. Tiffs study.provided an example of proactive treatment engineering, which is aimed at seeking a safe alternative to the use of poly.ers in sludge conditioning towards achieving a more sustainable sludge management strategy.

DNA takes on multi-different conformations such as A-, B-, C-, D- and Z-form. These conformations can transit to one another when DNA deposited in some metal ions solutions or when changing the concentrations of the same metal ions. Here, several major conformational transitions of DNA induced by.metal ions under different environment were introduced and the mechanism of the interaction of metal ions with DNA was discuss in detail.

The differential thermal analy.is （DTA） curves were measured at different heating rates in flowing air for study.ng the sy.thesis of the spinel liMn2O3 with li2CO3 and MnO2, The reaction began at about 503K, and finished at about 873K. The apparent activation energy.of Kissinger method was about ***^-1, the reaction orderwas 1.67, the freq.ency.factor was 7.81×10^9, and therefore the dinetic epuation was dδ/dt=A·exp（- E/RT）·（1-δ）^n=7.81×10^9, exp（-122770/RT）·（l-δ）^1.67 . Coats-Redfem integral method was used to analy.e the DTA curves of the samples at different heating rates, and the calculated apparent activation energy.and freq.ency.factor were 112. 13kJ· mol^-1 and 1.18 × 10^9, respectively. rather close to that of Kissinger method. X-ray.diffraction （XRD） and scanning electron microscope （SEM） results shown that the sy.thesized liMn2O3 possesses pure phase, regular shape and normal particle distribution.
