The eyes of all rabbits were removed and the homogenate of optic nerves was used to determine the contents of TXB_2 and 6-Keto-PGF_ 1α, and the metabolites of TXA_2 and PGI_ 2 by radioimmunoassay.

Methods Fetal cerebral hemispheres of Wistar rats at 15 - 18 days of gestation were dissected, dissociated, and planted. After cultured for 12 days,they were divided into 4 groups, those added with 100 nmol/L of T3,T4 and dexamethasone respectively were experimental groups.

After the model was successfully established,no treatments were given in group P.In group T,triptolide (0.05 g/L) was given by intraperitoneal injection 0.2 mg/kg.

METHODS: ① Model preparation: Model of right-side middle cerebral artery infarction was established in rats of rehabilitation group and model group, and no treatment was given to rats of normal control group.

This mixture is not only costly to separate but also produces a large aqueous stream that must then be disposed of or recycled.

In a majority of cases CO2 is viewed as waste to be disposed; however, with advanced technology, carbon sequestration can become a value-added proposition.

These relate to the chemical quality of the material, the quantity to be disposed of, its nature and origin, and its predicted impacts at the disposal site.

Annually, an amount of approximately 13 million cubic meters of hard-coal tailings must be disposed of in the German Ruhr Valley.

Sediments from stormwater retention ponds, roadside swales and street sweepings have to be disposed of or reused periodically.

In this paper analytic solutions for the natural frequency and mode of an oneway continuous four-sides supported rectangular ortothropic elastic plate with added masses and the steady response of the plate with complex damping under harmonic excitation are presented. The reaction of beams and added masses as well as con centrated forces are treated by means of Dirac δ function. The analytic solution is derived by means of finite Fourier transform. The solution thus obtained is a double trigonometric series and...

In this paper analytic solutions for the natural frequency and mode of an oneway continuous four-sides supported rectangular ortothropic elastic plate with added masses and the steady response of the plate with complex damping under harmonic excitation are presented. The reaction of beams and added masses as well as con centrated forces are treated by means of Dirac δ function. The analytic solution is derived by means of finite Fourier transform. The solution thus obtained is a double trigonometric series and it is simplified by summing up as a single series. The solution can be used for various supporting conditions taking care of the torsional rigidity of the supports and the beams.The solution is superior to the energy method. In the latter method the mode of vibration has to be assumed, which usually leads to some errors. For some special cases such as non-uniform spans, odd supporting conditions or those with large added masses, the error will likely be more serious.Some computational results are given and compared with the results of energy method and experiment. The results of the solution presented in this paper agrees well with the experimental results. Practically in computation only a few terms of the series are required for engineering accuracy.

This article, by utilizing the modern control theory, introduces the self-learning idea into speed control system to realize the closed loop control and increase the control characters. Based on the analysis of the much datas, defines designing conditions of humping self-learning link.The article gives emphasis to the researches of general constitute, the design of each part of self-learning link and give component method realized in computer. Detail program has be made for the main parts, data of more than 1000 cuts of ears have been handled and analized, on which, the feasibility of the constitute of self-learning link has been verified.

Using the techniques of stack, array and status, we derive a deduction algorithm of relational database operations that can give all answers to query and has a well-defined termination condition.
