    將菟絲子乾粉用75乙醇浸泡后，減壓蒸干后得到褐色漿狀物，經石油醚、氯仿、乙酸乙酯、正丁醇萃取，經柱層析后，再用葡聚糖凝膠對有效成份進一步純化，獲得了菟絲子中能誘導pc12細胞分化的活性組分。
  2. The study results indicated that, arranged in the order of magnitude, the degrees of the effects on the cementing strengths of the two interfaces were the system, emulsion, main emulsifier, fluid loss control agent and white oil respectively ; the cementing strength would be doubled and redoubled after being cleaned by preflush, especially by the system, emulsion and fluid loss control agent ; and, along with the increase in the mix slurry ratio, the initial and final set times of slurry would be obviously lengthened and the compressive strength of bond cement would be remarkably reduced or the slurry wouldn ' t be even set

    研究表明：對兩界面膠結強度的影響由大到小依次是體系、乳狀液、主乳化劑、降濾失劑、白油；前置液清洗后，膠結強度成倍提高，尤其對體系、乳狀液和降濾失劑清洗效果最佳；隨混漿比的增大，水泥漿初凝和終凝時間明顯延長，水泥石抗壓強度明顯下降，甚至不凝。
  3. In order to study the direct relation between oil - base drilling fluid performance and cement job quality, a new developed evaluation method ( artificial core method ) was adopted ; the effects of the oil - base drilling fluid system and its main components on the shear cementing strengths of the first and second interfaces in cementing operation were investigated ; and those of the different mix slurry ratios on the gel strength, initial set time, final set time of slurry and the compressive strength of bond cement were examined too

    摘要為了研究油基鉆井液性能和固井質量之間的直接關系，採用新建立的評價方法人工巖心法，考察了油基鉆井液體系及其主要組分對固井作業中第一、第二界面剪切膠結強度的影響規律，以及不同混漿比例下對水泥漿膠凝強度、初凝時間、終凝時間和水泥石抗壓強度的影響規律。
  4. The antimicrobial secretion could be divided into three sections, every section had antimicrobial activity. the first could be extracted by petroleum ether, the second could be extracted by ethyl alcohol, the third could dissove in water and could be separated by sephadex g - 50, g200 gel filtration chromatography and carbornmethyl cellulose - 1 anion - exchange chromatography and detected by a256, . the antimicrobial secretion had wide spectrum and had strong inhitory activity against germs and fungi, they could inhibit sixteen kinds of plant pathogenic germs, eight kinds of animal germs and eight kinds of plant pathogenic fungi

    粗提物經石油醚萃取可得第一個活性部分，剩餘部分經無水乙醇萃取可得第二個活性部分，剩餘物質再經凝膠sephadexg - 50後有兩個峰，第二峰有活性，再經凝膠sephadexg - 200後有三峰，第二峰有活性，將其經過陽離子交換柱cm - 1後有兩峰，此兩峰均有抑菌活性。
