To decrease maufacture costs and improve the ratio of efficiency and outlay.The not exensive emulsifier, hydrophobe and other adminicle were mixed with self-made polyesters, siloxane-polyester copolymers to obtain defoamers which be better than imported.And the factors in the process of compound were studied particularly and systemically.the prime project is as follows:the siloxane-polyester copolymer is synthesized with PPG2000,PEG400,1% hydrogen-containing Polyhydrosiloxanes, hexane diacid,which mol ratio of materials is 7:3:6:5.emulsifying agents are SP-60 and tw-60,the value of HLB is 8.5.its dosage is 5%.the concentration of control- bubble resin is 5%. the concentration of liquid hydrocarbon A is 20%.

为进一步降低消泡剂的生产成本，提高其使用时的效费比，采用价格低廉的乳化剂、疏水剂及其他助剂与所制聚醚酯、有机硅改性聚醚酯进行复配，制取了性能优于进口产品的优质消泡剂；并对复配工艺各要素进行了详细、系统的研究；最佳配方为：PPG2000、PEG400、含氢量1%的硅油，己二酸以物质的量之比为7：3：6：5制成的有机硅改性聚醚酯，乳化剂选择SP-60/TW-60组合、HLB值为8.5、用量5%，抑泡树脂用量5%，液态烃A用量20%，液态烃B用量10%，疏水剂用量15%～20%。

Otherwise, it is shown that there was no difference in alcoholicity, pH and total acidity of resultant young wine between ICF and FCF, but lower residual sugar and higher clarity degree could be obtained in the young wine of ICF.

另外，结果还表明，固定化发酵的杨梅果酒在酒精度、pH值以及总酸方面同游离发酵没有显著差别，但可获得比游离发酵更低的果酒残糖和更高的果酒澄清度。

The polyphenols of the beer fermented under the optimum processing was 101.78 mg/ L, which was close to the international standard 100 mg/L. The chroma, the total nitrogen, the total acid, pH, alcoholicity, diacetyl and CO2 of the product beer were close to that of Zhujiang beer

该优化工艺发酵的啤酒多酚值为101.78mg/L；总氮、色度、PH、总酸、酒精度、双乙酰、CO2与所测的珠江啤酒的指标接近。

When 5 mol% of 1a was used to catalyze the reaction at 0℃to room temperature, the aldol products were obtained with up to 96% ee, which were comparable to the effect with 30 mol% of L-proline as catalyst.

在0℃～室温下，以5mol％的1a催化即可获得相当或优于30mol％脯氨酸本身所具有的催化效果，ee值最高可达96％。

It was also found that the strength of FF specimen is close to the sumation of the strengths of FC and FS specimens with the same board thickness and screw spacing as FF specimen. As compared the test results with the research findings from Li [2]and Luo [3], It can be concluded that the failure mode of specimen is affected by both the sheathing thickness and the stud thickness. Different from this study, the failure mode of Li's test specimens is torsional-flexural buckling for most cases. The predicted values computed based on the AISI Specification seem to be conservative as compared to the tested values of FF specimens. Therefore, it is suggested that the effective length factor, K, can be taken as 0.5 to determine the wall stud assembly strength.

在三种不同试体组合分析时也发现，具外覆材支撑之立柱与外覆材受压内含支撑之立柱，两者之破坏强度相加，约等於具外覆材之墙体之破坏强度；试验结果与李岱真、罗浩之研究比较后，发现不同厚度之立柱与不同厚度之矽酸钙板之间束制关系明显影响强度之差异，且李岱真之试体破坏模式多为整体扭转-挠曲挫屈破坏，与本研究有较大差异；对於具外覆材之墙体与AISI预测值比较后，AISI规范预测值较保守，因此本研究有效长度系数建议采用0.5。

It was suggested that the raw waste liquid A was conditioned with hydrogen chloride to pH 4, then dosage of ferric chloride as 1200 mg/L for the rapid mixing 1 minute and slow mixing for 30 minutes, then after further settled in the clarifier for at least 1 ~ 2 hours, the effluent was treated by the oxidation with chloric acid for no more than 10 minuts in the dosage of 50 g/L or the correspond ORP value of 334 mV.

处理废液A在实厂操作流程中建议最先以降低pH值至4，在利用1，200mg/L氯化铁做为混凝剂，经由1分钟快混(100rpm)及30分钟慢混(10rpm)后，藉由混凝沉淀去除废液中之胶体，再使用50g/L氯酸钠作为氧化剂，反应时间为5分钟，氧化残余之COD，再利用ORP值为是否达334mV，藉以判断COD是否达终点。

The split between the two groups can hardly be papered over.
