本文报道用不含粘合剂的氧化铝薄层，以二甲苯-丙酮-无水乙醇-二乙胺(50：40：10：0.6)为展开剂分离茄科植物中的莨菪碱、东莨菪碱、山莨菪碱、樟柳碱及红古豆碱等五种莨菪烷生物碱，用改良Dragendorff试剂-Wagner试剂(1：1)显色，定量收集莨菪碱、东莨菪碱及山莨菪碱的斑点，莨菪碱和东莨菪碱用氨甲醇洗脱，蒸干洗脱液后分别用pH 5.6及pH 4.5的溴甲酚绿溶液作比色测定；山莨菪碱用4％醋酐氯仿洗脱，蒸干洗脱液后用pH 5.6的溴甲酚绿溶液作比色测定。

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。

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.

在低压低渗透气藏的压裂改造过程中，常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题，一是压裂液滤液对低压低渗透气层造成的水锁损害；二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的，对碱敏性储层造成碱敏损害，降低储层渗流能力；三是地层压力低，压裂液返排能量不足，当前各油田采取的措施主要是&液氮伴注&技术，但是&液氮伴注&技术增加了压裂的费用，而且液氮存放也存在较大问题。

AIM: To compare the miosis and intraocular pressure (l0P) lowering effects of timololpilocarpine fixed-ratio combinations between domestic eyedrops (0.5% timolol and 2% pilocarpine nitrate) and imported eye drops (0.5% timolol and 2% pilocarpine hydrochloride) on pupil and intraocular pressure in rabbits.

1 Filling amount: 30 tons of bamboo counted with liquor filled tank and circularly press the bamboo flakes for 3-4 minutes during boiling,(the data results from repeated experiments), if the filling amount is too less, the hardness is low, too much alkali remnant, and the pulp yield will be low; if the filling amount is too much, the cooking liquor can not be dried completed, and the circulation amount is too less, the electric current of circulating pump is too low, it will be difficult to cook, and there will be too much pulp knots with high hardness and less alkali remnant which may lead to unripe pulp.

3.1.1装锅量：竹子30吨是以液浸装锅和开中循环压竹片3——4分钟为计，（数据是根据多次实验得出的结果）如装锅量太小，硬度低，残碱大，浆得率低，装锅量太大蒸煮液无法完全送完，循环量小，循环泵电流小，蒸煮困难，浆节子多、硬度高、残碱小，有可能造成生浆。

And we also get the fact that many vat dyestuffs can not be suitable for spun-dyed for viscose as dyed-reagents with the way of "reducing-oxidizing", such as C.I. Vat Blue 6, C.I. Vat Red 29, C.I. Vat Black 29, C.I. Vat Orange 1, C.I. Vat Brown 3 and so on. But some vat dyestuffs have a stable color, such as C.I. Vat Green 3, C.I. Vat Black 8 and so on.

通过实验可知，还原蓝BC、还原大红R、还原灰BG、还原金黄RK、还原棕R等还原染料，在高浓度碱剂、带碱氧化等加工条件下会产生不可逆的色光变化，而且变化程度较大，使得这些染料均不能以&还原－氧化&方式应用于粘胶的纺液着色加工，而还原橄榄绿B、还原灰M等染料受高浓度碱剂、带碱氧化等因素的影响较小，色光较为稳定。
