coulomb field meaning in English
库仑场
库仑静电场
Examples
- Due to the repulsive coulomb field , the effective impact parameter increases , and therefore the calculated reaction cross section decreases
库仑场的排斥效应使得核?核反应有效的碰撞参数增大，使计算的反应截面减小，同时这种修正的效应随能量增大而减小。 - Presently , the laser pulse from the high power ultrashort laser system is several femtoseconds in duration , tw ( or pw ) level in peak power , 1020 w / cm2 ( or 1021 w / cm2 ) in focusing power density , according electric field is much stronger than coulomb field in atoms
目前，高功率超短脉冲激光放大系统输出的激光，脉宽达到几个飞秒，峰值功率达到太瓦甚至拍瓦量级，聚焦功率密度达10 ~ 20w cm ~ 2 ，甚至1021w cm2 ，相应的电场比原子内库仑场强得多。 - Recent progress in ultrafast optics has allowed the generation of ulfcraintense light pulses comprising merely a few field oscillation cycles . the arising intensity gradient allows electrons to survive in their bound atomic state up to external field strengths many times higher than the binding coulomb field and gives rise to ion - ization rates comparable to the light frequency resulting in a significant extension of the frontiers of nonlinear optics and ( nonrelativistic ) high field physics
随着超快光学技术的发展，仅含几个振荡周期的超强脉冲已经能产生，且其强度梯度可使电子存在比库仑束缚场高许多倍的外场产生的原子束缚态上，并产生了同光频相差不大的电离率，从而促进了非线性光学前沿及非相对论的强场物理的延伸。 - The optical - limit glauber theory has been of great success in describing the stable nucleus scattering at high energies . as it is extended to the nucleus scattering at low and intermediate energies , the modification of the coulomb field to the effective impact parameter and the diffuseness of the nucleon - nucleon ( n - n ) scattering in the forward direction has to be taken into account
其中光学极限近似的glauber模型能很好地描述高能小角度的稳定核散射，进一步推广应用于研究中低能稳定核散射时，需要考虑库仑相互作用对有效碰撞参数的修正和核子?核子两体散射在朝前方向的弥散。 - It has high selectivity in adsorpting water , polar molecule or polarizable molecule on account of the existing of mighty coulomb field and polar interaction in the internal of crystal cave of zeolite , the high electric field gradient and the uneven surface caused by the exposure of exchangable cation of equilibrium framework negative charge in framework structures
由于分子筛晶穴内部有强太原理工大学硕士学位论文摘要大的库仑场和极性作用，再加上骨架中大量平衡骨架负电荷的可交换阳离子的暴露造成的高电场梯度及表面的不均性，使其对水、极性分子及可极化的分子具有高选择的吸附性能。
