  2. （１）　13頁の（重イオン衝突の特徴の）記述の修正　（１）　13頁の（重イオン衝突の特徴の）記述の修正　 11頁 ９~１１行目 Fig.4: mt -spectra Among two distinctive features of mt spectrum in relativistic heavy ion collisions, only the former one is owing to the expansion of fireball. CERN-SPS-WA98 SusumuSATO

  3. （２）　運動量分解能の運動量依存の定性的記述の追加（２）　運動量分解能の運動量依存の定性的記述の追加 45頁 6~9行目 For lower momentum, mainly because of multiple scattering, for higher momentum, mainly due to position resolution. CERN-SPS-WA98 SusumuSATO

  4. （３）　mt分布の誤差に関してアクセプタンスのy, pt相関の影響の考察 77頁 14~17行目 While geometrical acceptance has y-pt (or mt) correlation, the effect is smaller (~2.5%) in the pion mt-spectrum. CERN-SPS-WA98 SusumuSATO

  5. （４, ５）　熱膨張模型におけるsingle spectra 評価方法の記述、及び陽子spectrumのfitの妥当性の検討(その１) 85頁 Expression 1 As a function of T, bt Eur.Phys.J. C2(1998)661 →陽子spectrum（WA98)について、fittingを行う CERN-SPS-WA98 SusumuSATO

  6. （４, ５）　熱膨張模型におけるsingle spectra 評価方法の記述、及び陽子spectrumのfitの妥当性の検討(その2) 45頁、図43 76頁19~21行目 T=143±8MeV, bt =0.40c±0.05c→consistent with NA44 results CERN-SPS-WA98 SusumuSATO

  7. （６）　Mixed Event 法の正当性の記述の追加 55頁 6~12行目 ● Dominated by combinatorial background ● Effect of two-track separation are evaluated to be small ( Chamber resolution (~some mm) < Nominal track distance (~few tens cm) ) CERN-SPS-WA98 SusumuSATO

  8. （７）陽子、π中間子のdN/dyの 値を追加 70頁 2~18行目 dNp/dy＝25±6, dNp+/dy ＝138±16 　　　　　　（←consistent with other experiment） CERN-SPS-WA98 SusumuSATO

  9. CERN-SPS-WA98 SusumuSATO

  10. （４, ５）　熱膨張模型におけるsingle spectra 評価方法の記述、及び陽子spectrumのfitの妥当性の検討(その１) 85頁 Expression 1 As a function of T, bt Eur.Phys.J. C2(1998)661 →陽子spectrum（WA98)について、fittingを行う CERN-SPS-WA98 SusumuSATO
