广东省生产力促进工作发展报告

广东省生产力促进工作起步于“八五”末期，1994年在广东省技术开发中心的基础上首先成立了广东省生产力促进中心，同年8月深圳市生产力促进中心成立：1995年东莞市生产力促进中心和广州市荔湾区生产力促进中心相继成立。“八五”期间广东省共建立生产力促进中心4家。     

合成烯丙基砜的新方法

报道一种简单、便利的一步合成烯丙基砜的新方法。     

二元样条S_3~1(Δ_2)的基函数及最小支集

设Δ_2是平面区域Ω=[a,b,c,d]的四方向剖分,S_3~2(Δ_2)是在Δ_2分划下的光滑度1和次数3的二元样条函数空间。利用B-网方法,我们构造了由七片多项式组成的B样条基,并证明了给B样条基具有最小支集。最后,附带给出了基函数的若干简单性质。     

Nuclear Shadowing Effect on the K Factor in Au—Au Collisions

We investigate the nuclear shadowing effect on the K factor in the Drell-Yan process by introducing a Shadowing factor into the corresponding quantum chromodynamical αs order corrections.K factors for Au-Au collisions are calculated at the centre-of-mass system energies √s=60,130 and 200 GeV while the nuclear shadowing factor is taken into account.The numerical results indicate that the nuclear shadowing factor obviously raises the K value in the small x region,and for the same nucleon the K valus becomes smaller as the energy increases.The nuclear shadowing effect could be one reason for creating the non-constancy of the K factor.     

Realization of the Fredkin Gate by Three transition Pulses in a Nuclear Magnetic Resonance Quantum Information Processor

We have experimentally realized the Fredkin gate with only three transition pulses in a solution of alanine.It appears that no experimental realization of the Fredkin gate with fewer pulses has been reported yet.In addition,the simple structure of our scheme makes it easy to implement in experiments.     

New Explicit Solitary Wave Solutions and Periodic Wave Solutions for the Generalized Coupled Hirota－Satsuma KdV system

In this paper,we study the generalized coupled Hirota-Satsuma KdV system by using the new generalized transformation in homogeneous balance method.As a result,many explicit exact solutions,which contain new solitary wave solutions,periodic wave solutions,and the combined formal solitary wave solutions,and periodic wave solutions ,are obtained.
