  1. The knowledge of these initial collision is crucial for any theoretical treat - ment of a possible parton - hadron phase transition, the detection of which being the ultimate aim of all the efforts of co1liding heavy ions at very high energies. the parton model allows to calculate inclusive cross sections as a convolution of any elementary cross section with parton distribution functions, assuming that factorization works. the disadvantage is that tlle first interaction is coilsidered quite differently from the subsequent ones in case of multiple scattering

    其它的弦模型在計算幾率時,忽略了入射能量在pomeron之間的分配,破壞了能量守恆,而且把pomeron作為全同粒子處理,即pomeron之間是不可區分的;然而在處理粒子產生時,這些模型雖然考慮了能量守恆,但是第一個pomeron的粒子產生與其它的pomeron很不一樣? ? pomeron在粒子產生時不是全同的。
  2. The coupled equation method ( cem ) has been improved to calculate 4s subshell of mnl by adding 3d ~ ( 5 ) ( ( 4 ) ~ x ) 4s ( ( 5 ) ~ x ) channels, which were verified to play a key role to the magnitude of resonance structure due to the interaction between 4s kp transition and 3p 3d excitation. our calculation shows higher symmetry and a solo peak near 51. 7ev, which is in better agreement with experimental data than garvin ' s calculation. except 3p 3d giant resonance, there are obvious 3p nd ( n > 4 ) rydberg resonances with width in the total cross section of mnl

    在研究錳原子4s殼層的共振結構時,我們首次在耦合方程方法中加入了3d ~ 5 ( ~ 4x ) 4s ( ~ 5x )通道與大共振之間的相互作用,發現這類通道對於4s殼層的共振結構具有較大的貢獻,從而改善了在耦合方程方法中只考慮基態3d ~ 5 ( ~ 6s ) 4s ( ~ ( 7 , 5 ) s )的缺陷,為精確計算其他過渡金屬原子外殼層的共振結構做了很好的鋪墊。
  3. The magnitude of these variables increased approximately ten times. it helped the rapid releasing of instability energy. the interaction of high - level and low - level mesoscale system leads to the rainstorm. the vertical cross section analysis of potential temperature tells us that rainstorm take place in the warm - moist and instability area. usually locate in the very stiff moist isentropes and it can lead to the development of vortex

    通過對相當位溫的垂直剖面分析,可知兩場暴雨的中低層都為暖濕不穩定區,暖濕不穩定區上部冷空氣明顯擴散,暴雨產生在暖濕對流不穩定區內,通常產生在_ e陡峭和密集區中, _ e陡峭和密集區有利於渦旋發展。
  4. ( 2 ) respectively by elastic theory analyses and methods of structural mechanics, transverse static analytical equations for flexible pipeline rigid pipeline are established whose outcomes are applied in numerical example to compare those with that by finite element method. ( 3 ) considering interaction of filled soil, pipeline and foundation, with an eye to non - linear soil model, in view of the initial geo - stress field and the effects of interface between soil and pipeline, and by finite element method the calculational model and method are built for transverse stress in pipeline. then, by the great finite element analytical software ansys, those outcomes are applied in calculation example of positive buried pipe to educe the distribution of circumjacent soil pressure and stresses on cross section and to compare it with that calculated by conventional ways before those outcomes are applied in engineering case of positive buried pipe with flexible filled materials to confirm distribution of soil pressures after the measure for reduction and to compare it with measurements. as a result, the model set up in this paper is proved to be applicable after all above - mentioned analyses
