The phase equilibrium data of SBO-FAME-Methanol, SBO-FAEE-Ethanol and Glycerol-FAEE-Ethanol systems were measured. The results indicated that it involved two different stages: liquid-liquid-solid reaction stage and liquid-solid reaction stage. When the molar ratio of methanol to oil is 12:1 at 65℃, the turning point is at a 55% biodiesel yield. The liquid-liquid-solid reaction model was proposed based on the double-membranes theory. It indicated that the process is reaction and mass transfer controlled together at the first stage, and the second stage is reaction controlled. The predictions of the model are matched with the experimental results.In the end, the acid was extracted using methanol and ethanol from jatropha curcas l oil.

测定了生物柴油制备过程中的SBO-FAME-Methanol、SBO-FAEE-Ethanol、Glycerol-FAEE-Ethanol三组分相平衡数据，表明固体碱催化过程分为液-液-固和液-固两个反应阶段，在醇油摩尔比为12：1、65℃的初始反应条件下，转化率达到55%时，为第一阶段向第二阶段的转折点；基于双膜理论建立了固体碱催化制备生物柴油的非均相液-液-固反应模型，表明两个反应阶段分别为传质、反应共同控制和反应控制，模型计算值与实验值吻合较好。

2Similar to other shrimps, artificial pond culture Penaeus monodon also had difference in growth between female and male. At early culture period, the difference between them was not distinct, but the female would grow more quickly than male after the fifty-ninth day. The body weight growth turning point of the male appeared at the 144.5 days, and at the 195. 3 days for the female.(3) By using Von Bertallanffy growth equation, the growth equations of Penaeus monodon were abtained.

养殖前期，雌、雄虾的体长、体重生长差异不明显，雄虾略高于雌虾，在59.6d后，雌虾体长生长速度高于雄虾；雄虾体重的生长拐点出现在144.5d左右，雌虾体重的生长拐点出现在195.3d左右；(3)采用von Bertallanffy生长方程，拟合出池塘养殖斑节对虾体长、体重生长方程为：。

The visit to the great Paris Exhibition at the end of the 19th century, by a gamelan orchestra from Peliatan in Bali, was a turning point both literally and symbolically for all the artists and composers who saw and heard it.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
