  9. Our model introduces the general equations of chemical evolution used in galaxies to studies of gcs. in this model the important gas outflow caused by the supernova explosion and other processes during the formation of globular clusters is included. based on such a self - enrichment model, monte carlo method is used to simulate the formation and chemical evolution of globular cluster systems, from which a new explanation of the bimodal metallicity distribution can be given

    本文把星系演化中通用的化學演化方程引入到球狀星團這一系統中來，特別考慮到球狀星團中恆星形成過程中超新星爆發等因素引發的氣體外流，把這一重要的物理過程包含到化學演化方程中，並用蒙特卡羅方法來模擬球狀星團系統的自增豐演化。
  10. Ductility enhancements were achieved in nano - structured metals through the incorporation of a bimodal grain size distribution, with micrometer - sized grains embedded inside a matrix of nano - crystalline grains, and at the same time the strength deceases so little that the nano - crystalline material is toughening well

    針對這種情況國外研究人員制備出的一類具有不同晶粒尺度分佈的納米晶材料，在強度降低有限的情況下改善了材料的塑性性能，達到了增韌的目的。
