The main factors effecting adaptive scheduling program design are illustrated. The examples fox analyzing the restrictions which effect the reasonable application to radar resources are given. Finally, Linear Programming Mathematical Model of adaptive scheduling program design restriction is brought out.

A reconfigurable design methodology for small agriculture machinery (SAM) product development was proposed. Case based reasoning (CBR) technology was employed in the reconfigurable design process, and it has been studied in detail. With the design restriction of the die of gearbox shells, a case study has been conducted in the gearbox of SAMJSX5D reconfigurable design that helped to illustrate the proposed approaches.

Finally, by optimization technology, the result indicates that the wing could satisfy the design need with lighter structural weight, in the precondition of given design restriction of aeroelastic tailoring, when the orientation of ply angle heads the leading edge of the wing.

The influence of the into /out of ring coupling coefficients on the bandwidth and extinction ratio of the spectral band was investigated and the design restriction among them and free spectral range was discussed.

If PV orientation is not perceived as a design restriction, architects will be much more open to their use.

Using oligo (dT)12～18as primer and mRNA from porcine pituitary gland as template, the first strand of cDNA was synthesized by AMV reverse transcriptase; and then the second strand of cDNA was replicated by E. colt DNA polymerase I after cutting mRNA into oligonucleotides with RNaseH. The full-length of double strand cDNA was thus obtained with further treatment by E. colt DNA ligase and T. DNA polymerase. On the basis of the known DNA sequence for porcine growth hormone, a pair of specific primers were designed...

The full-length of double strand cDNA was thus obtained with further treatment by E. colt DNA ligase and T. DNA polymerase. On the basis of the known DNA sequence for porcine growth hormone, a pair of specific primers were designed and synthesized. Subsequently, polymerase chain reaction for amplifying the sequence encoding mature porcine growth hormone was conducted using these primers and synthesized template. Electrophoresis and southern blotting showed that the amplified fragment by PCR was the unique DNA sequence of mature porcine growth hormone,flanked by designed restriction site and codon sequences.

From the summary of the advantages and disadvantages of some curved route design thoughts and methods based on splines,this paper presents the design method based on cubic geometrical splines for "transition-circle-transition"combination form usually used in horizontal alignment design of interchange ramps,which gives full play to characteristics of cubic geometrical splines' smooth and continuity,simple calculation and correspondence with horizontal alignment,establishes relations between...

ln terms of the method of multiple scales in nonlinear oscillations, superharmonic and subharmonic resonance' s of hydrogenerator rotors caused by unbalanced magnetic pull are discussed when both mass and assembling eccentric of the rotors are taken into account. Considering nonlinear properties of the unbalanced magnetic pull, such phenomena are discovered that if the critical speed of rotors is close to 2 or 3 times as much as the rotary speed, the superharmonic resonance occurs, and as the same way if the...

ln terms of the method of multiple scales in nonlinear oscillations, superharmonic and subharmonic resonance' s of hydrogenerator rotors caused by unbalanced magnetic pull are discussed when both mass and assembling eccentric of the rotors are taken into account. Considering nonlinear properties of the unbalanced magnetic pull, such phenomena are discovered that if the critical speed of rotors is close to 2 or 3 times as much as the rotary speed, the superharmonic resonance occurs, and as the same way if the critical speed is close to 1/ 2 or 1/3 times as much as the rotary speed, the subharmonic resonance occurs, too. Correctness of conclusions from the theoretical analysis is verified by model experiment results and new design restrictions for the hydrogenerator rotors are suggested simultaneously.
