By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.

When RN was 25%∶75%,N and amylum were lowest,and volatile base were highest.With 100% ammonium,reducing sugar,Cl and amylum were highest,and K/Cl,nicotin and K were lowest.With 100% nitrate,the content and uptake of N,K and Cl were the lowest;3 Any RN,the content of nicotin,N,K,Cl and amylum satisfied the demand of high quality tobacco,reducing sugar was on the other way round.

RN为25%∶75%时，挥发碱含量最高，总氮、淀粉含量最低。100%铵态氮时，还原糖、氯含量、淀粉的含量最高，碱、钾、钾氯比最低，同时显著地降低烤烟的等级结构。100%硝态氮时，总氮、钾、氯在烟叶中的含量最低，吸收总量也最少，同时产量、产值、均价也处于最低水平；3本试验的任何RN下，烟碱、总氮、钾、氯、淀粉的含量均符合优质烟叶要求，而还原糖相反。

The results showed that the W content in the electrodeposits rose with the increasing of cathodic current density in the solution containing ammounium citrate as complexing agent,whereas the current efficiency remained approximately constant. When the current denisity was higher than 15 A/dm2, the W content in the alloy was not obviously changed, but the current efficiency remarkably decreased.
