  • We analyze the microstrain and density changing of the composite powders during pressing . the density evolution of ti / al composite billet became calm when the pressure get to 1000mp . the technique of vacuum degassing can reduce the content of atmosphere
    分析了复合粉在冷压制过程中的微观变形过程,不同压力下的密度变化趋势,表明在冷压制压力达到1000mpa后复合粉预制坯密度变化趋于平稳。
  • It is found that the fwm field can cause the asymmetry of electromagnetically induce transparency profile . in addition , the effect of different propagating orientations of probe field on the electromagnetically induced transparency is also discussed . in the molecular multi - level system with the perturbed superposition levels , we discuss the electromagnetically induced transparency , spontaneous emission enhancement , double dark resonance and double electromagnetically induced transparency by using the density matrix equation under weisskopf - winger approximation and dressed - state density matrix equation
    针对实际的实验条件,考虑了一种影响量子干涉的新的因素-四波混频场,研究了四波混频场对双光子探测的-型能级体系的eit的影响,发现四波混频场能够导致双光子探测的eit线型的不对称,在此基础上,讨论了不同探测场的传播方式对eit的影响,针对分子中实际存在的包含有微扰能级的不同多能级系统,我们分别采用缀饰态绘景下的密度矩阵方程和weisskopf - wigner近似下的密度矩阵方程详细地讨论了电磁感应透明、自发辐射的干涉相消和相长、双暗态共振和双电磁感应透明现象。
  • Sequence and large sample quality are posed . in our country or allien there are many experts who discusses some quanlity of na variable in great . for example , in documentation 6 , there is a discussion about the consistency of density kernel estimation and many results have been g ained , but the density estimation f ( x ) is limited to the arrange of x [ a , 6 ] which limits the arrange of application . thus in this passage we call off this limitation and further discuss the density kernel estimation under na sample . consequently the counterpart results have been gained and the condition of result has been weaked . in the same time we discuss the density kernel estimation under pa sample and the counterpart result has been gained
    序列密度函数估计及其大样本性质的研究课题。国内外许多专家对na变量的各种性质进行了大量的讨论,其中文献[ 6 ]曾对na样本下密度核估计的相合性进行了讨论,并取得了一些结果,但该文将密度估计f ( x )限制在x [ a , b ]中进行讨论,这局限了应用范围。因此本文在取消这种限制条件下对na样本的密度核估计进行了进一步的讨论,得出了相应的结果,并使结论的条件得到弱化;同时对pa样本下的密度估计也进行了相应的讨论,取得了相应的结果。
  • The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent . it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger . we compare our results with those in a simple method , where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
    首先我们要求在每一个密度及各种不对称系数的核物质中,相对论平均场( rmf )计算出的核子标量与矢量自能与dbhf计算出的标量与矢量自能一致,从而得到在rmf下的密度依赖的有效介子核子耦合常数,包括同位旋标量介子。
