高校自主权与学位纠纷

高校自主权本质上是一种从权力,从属于法律、法规。我国高校的自主权在扩大后,并不包括自主决定学位授予条件。获得中国学位,只要满足三个方面的条件:一是拥护中国共产党的领导,拥护社会主义制度,拥护中华人民共和国宪法,遵守法律、法规;二是达到一定学术水平或者专门技术水平;三是申请。这三个条件的核心是第二个条件即学术条件。高校自主权侧重点在于教学学习管理,学位纠纷侧重点在于学生的学术水平是否合格。高校自主权与学位纠纷二者之间没有契合点。司法实践中,以高校自主权作为审判学位纠纷的理由,没有法的依据,也违背了《行政诉讼法》合法性审查原则。

Thermal Dehydration Kinetics of Gypsum and Borogypsum under Non-isothermal Conditions

Thermal dehydration of gypsum and borogypsum was investigated under nonisothermal conditions in air by using simultaneous thermogravimetric-differential thermal analyzer. Nonisothermal experiments were carried out at various linear heating rates. Kinetics of dehydration in the temperature range of 373-503 K were evaluated from the DTA (differential thermal analysis)-TGA (thermogravimetric analysis) data by means of Coats-Redfern,Kissinger and Doyle Equations. Values of the activation energy and the pre-exponential factor of the dehydration were calculated. The results of thermal experiments and kinetic parameters indicated that borogypsum is similar to gypsum from dehydration mechanism point of view although it consists of boron and small amount of alkali metal oxides.

Technological conditions and kinetics of leaching copper from complex copper oxide ore

The kinetic behavior of leaching copper from low grade copper oxide ore was investigated. The effects of leaching temperature, H2SO4 concentration, particle size of crude ore and agitation rate on the leaching efficiency of copper were also evaluated. And the kinetic equations of the leaching process were obtained. The results show that the leaching process can be described with a reaction model of shrinking core. The reaction can be divided into three stages. The first stage is the dissolution of free copper oxide and copper oxide wrapped by hematite-limonite ore. At this stage, the leaching efficiency is very fast （leaching efficiency is larger than 60%）. The second stage is the leaching of diffiuent copper oxides, whose apparent activation energy is 43.26 kJ/mol. During this process, the chemical reaction is the control step, and the reaction order of H2SO4 is 0.433 84. The third stage is the leaching of copper oxide wrapped by hematite-limonite and silicate ore with apparent activation energy of 16.08 kJ/mol, which belongs to the mixed control.

Theoretical research and practical application of Mathematical economic models

Mathematical economic modeling is widely used to provide a reference for policy makers and guidance for the specific work of many departments, such as saving expenditures, reducing costs and improving profit. Particularly, it can predict and estimate the future, playing a great role in promoting the rapid development of science and technology as well as the management of market economy. In general, mathematics does not directly deal with the objective conditions on the management of market economy. In order to use mathematics to solve problems in the field of the management of market economic, it is necessary to carry out mathematical economic modeling.

Modeling Topology and Nonlinear Dynamical Behavior of the Weighted Scale-Free Networks

An improved weighted scale-free network, which has two evolution mechanisms： topological growth and strength dynamics, has been introduced. The topology structure of the model will be explored in details in this work. The evolution driven mechanism of Olami-Feder Christensen （OFC） model is added to our model to study the self-organlzed criticality and the dynamical behavior. We also.consider attack mechanism and the study of the model with attack is also investigated in this paper. We tlnd there are differences between the model with attack and without attack.

Economic and Social Impact of Advanced Research at Universities

The major purpose of any university is high-quality education of its students for the needs of society. Qualified staff （including teachers and administration） is the necessary condition for high-quality education of students. The qualified staff （university teachers） can only be internationally competitive when they do high quality research andactively participate in the university management. Government and industry set up the ＂boundary conditions＂ for universities, but they should not interfere into the internal self-governance of the universities, and should respect academic freedom. A world-class university has its own Triple Helix uniting education, research and innovation. A few specific examples of practical realization of such ＂sub＂ Triple Helix are given, which are based on personal experience of the author during 24 years of his work as a professor at leading universities in the USA, Germany and Japan. Though some findings and conclusions may have limited use in any particular country, there are universal features that should be present in any modem university interested in increasing its impact on local environment, concerned with interaction to local government and local businesses, and striving for top positions in international rankings.

Mechanical response features and failure process of soft surrounding rock around deeply buried three-centered arch tunnel

Due to the extreme complexity of mechanical response of soft surrounding rock(SR) around a tunnel under high geostatic stress conditions, the integration of physical and numerical modeling techniques was adopted. Based on the similarity theory, new composite-similar material was developed, which showed good agreement with the similarity relation and successfully simulated physico-mechanical properties(PMP) of deep buried soft rock. And the 800 mm×800 mm×200 mm physical model(PM) was conducted, in which the endoscopic camera technique was adopted to track the entire process of failure of the model all the time. The experimental results indicate that the deformation of SR around a underground cavern possessed the characteristics of development by stages and in delay, and the initial damage of SR could induce rapid failure in the later stage, and the whole process could be divided into three stages, including the localized extension of crack(the horizontal load(HL) was in the range of 130 k N to 170 k N, the vertical load(VL) was in the range of 119 k N to 153.8 k N), rapid crack coalescence(the HL was in the range of 170 k N to 210 k N, the VL was in the range of 153.8 k N to 182.5 k N) and residual strength(the HL was greater than 210 k N, the VL was greater than 182.5 k N). Under the high stress conditions, the phenomenon of deformation localization in the SR became serious and different space positions show different deformation characteristics. In order to further explore the deformation localization and progressive failure phenomenon of soft SR around the deeply buried tunnel, applying the analysis software of FLAC3 D three-dimensional explicit finite-difference method, based on the composite strain-softening model of Mohr-Coulomb shear failure and tensile failure, the calculation method of large deformation was adopted. Then, the comparative analysis between the PM experiment and numerical simulation of the three centered arch tunnels was implemented and the relationship of deformation localization and progressive failure of SR around a tunnel under high stress conditions was discussed.

Measurement of Collision Conditions in Magnetic Pulse Welding Processes

MPW （magnetic pulse welding） is a solid state joining technology that allows for the generation of strong metallic bonds, even between dissimilar metals. Due to the absence of external heat, critical intermetallic phases can largely be avoided. In this process, Lorentz forces are utilized for the rapid acceleration of at least one of the two metallic joining partners leading to the controlled high velocity impact between them. The measurement of the collision conditions and their targeted manipulation are the key factors of a successful process development. Optical measuring techniques are preferred, since they are not influenced by the prevalent strong magnetic field in the vicinity of the working coil. In this paper, the characteristic high velocity impact flash during MPW was monitored and evaluated using phototransistors in order to measure the time of the impact. The results are in good accordance with the established PDV （photon Doppler velocimetry） and show a good repeatability. Furthermore, the collision front velocity was investigated using adapted part geometries within a series of tests. This velocity component is one of the key parameters in MPW; its value decreases along the weld zone. With the help of this newly introduced measurement tool, the magnetic pressure distribution or the joining geometry can be adjusted more effectively.

Comparison of the effects of deep and moderate neuromuscular block on respiratory system compliance and surgical space conditions during robot-assisted laparoscopic radical prostatectomy: a randomized clinical study

Objective:Robot-assisted radical prostatectomy(RARP)requires pneumoperitoneum(Pnp)and a steep head-down position that may disturb respiratory system compliance(Crs)during surgery.Our aim was to compare the effects of different degrees of neuromuscular block(NMB)on Crs with the same Pnp pressure during RARP.Methods:One hundred patients who underwent RARP were enrolled and randomly allocated to a deep or moderate NMB group with 50 patients in each group.Rocuronium was administered to both groups:in the moderate NMB group to maintain 1–2 responses to train-of-four(TOF)stimulation;and in the deep NMB group to maintain no response to TOF stimulation and 1–2 responses in the post-tetanic count.Pnp pressure in both groups was 10 mm Hg(1 mm Hg=133.3 Pa).Peak inspiratory pressure(Ppeak),mean pressure(Pmean),Crs,and airway resistance(Raw)were recorded after anesthesia induction and at 0,30,60,and 90 min of Pnp and post-Pnp.Surgical space conditions were evaluated after the procedure on a 4-point scale.Results:Immediately after the Pnp,Ppeak,Pmean,and Raw significantly increased,while Crs decreased and persisted during Pnp in both groups.The results did not significantly differ between the two groups at any of the time points.There was no difference in surgical space conditions between groups.Body movements occurred in 14 cases in the moderate NMB group and in one case in the deep NMB group,and all occurred during obturator lymphadenectomy.A significant difference between the two groups was observed.Conclusions:Under the same Pnp pressure in RARP,deep and moderate NMBs resulted in similar changes in Crs,and in other respiratory mechanics and surgical space conditions.However,deep NMB significantly reduced body movements during surgery.
