酸洗抑雾缓蚀剂的研制

带有废酸脱硅再生系统的酸洗机组对于所用抑雾缓蚀剂有特殊的要求。它要求所用抑雾缓蚀剂既具有高的抑雾效果，其缓蚀率又要适当；既不影响脱硅和铁红质量，更不能对系统造成堵塞和影响系统物料的平衡。针对上述要求研制出特效的酸洗抑雾缓蚀剂。     

济源凹陷油源追踪及烃类垂直运移作用

济源凹陷为一中、新生代复合型断陷．下第三系原油为轻质、低硫原油，与下伏中生界（Ｔｔ－Ｊ２）湖沼相生油岩抽提物具有同源性，而与下第三系泥岩抽提物回然相异。后邓断裂是烃类垂直运移的良好通道，中生界生成的烃类沿断裂经过了约３０００－４０００ｍ的垂直运移而聚集成芷。长距离的垂直运移造成了原油中ｒ－蜡烷的富集，作为运移通道的断裂发育时间、规模等控制了浅层油芷的分布．     

Purification of platelet-derived endothelial cell growth inhibitor and its characterization as transforming growth factor-β type 1

In 1986, Brown and Clemmons (Proc. natl Acad. Sci. USA83 (1986) 3321) showed that platelets contain a substance, platelet-derived growth inhibitor (PDGI), that inhibits in vitro endothelial cell replication. Although platelets are rich in transforming grwoth factor (TGF-), PDGI was considered not to be related to TGF-, on the basis of its reported properties (extraction from platelets at neutral pH, binding to heparin-Sepharose). However, we purified PDGI to near homogeneity and showed that on the basis of HPLC retention behavior, in vitro growth inhibitory activities with several cell types, receptor binding, and immunoneutralization of growth inhibitory activity with specific anti-TGF- type 1 antibodies, PDGI is most probably identical with TGF- type 1.     

Cooperative inhibitory effect of follicular fluid and cAMP on hamster oocyte maturation

Summary Porcine or human follicular fluid inhibited the spontaneous maturation of isolated hamster oocytes in vitro during the first 1.5 h of culture. Moreover, the presence of 50% follicular fluid combined with 100 M dbcAMP cooperatively reduced the incidence of germinal vesicle breakdown. The addition of FSH also inhibited the resumption of meiosis, and the presence of LH did not overcome the inhibitory effects of follicular fluid and tended to impede isolated hamster oocyte maturation in vitro.     

吉木萨尔陆相页岩油微观赋存类型

为了更好地认识页岩油微观赋存状态及类型,避免实验过程中水钻取样对原油分布的影响,选取吉木萨尔页岩典型含油岩芯,采用全程液氮钻、切、磨制样工序,通过全能谱扫描电子显微镜、二次电子成像及背散射相结合的技术手段,获得微观储层矿物类型和结构、储集空间类型、形貌以及C, O, Si, Al, Ca, K, Na,Mg等元素在微、纳米尺度的分布。依据去除矿物因素后的C元素含量分布,判别原油在微、纳米空间尺度的富集程度。结合矿物岩石组构和储集空间形貌,对微、纳米尺度页岩油原油的赋存状态及分布类型进行直观的定量表征,并基于C元素含量推测微观含油饱和度的相对变化。针对原油与孔喉的配置关系,进行储层微观孔喉结构与原油赋存状态的表征,明确原油赋存类型。总结出研究区4种微观原油赋存类型:白云质溶蚀微米级大孔道中的可动油、砂质粒间微纳米级孔中可动油、砂质粒间孔喉壁吸附的半束缚状态的油膜以及自生黏土矿物晶间孔内束缚油。

采用失重法考察了６种具有Ｋｅｇｇｉｎ结构的含钼杂多酸盐在ＮａＣｌ介质中对碳钢的缓蚀作用。实验表明,所研究的化合物均有一定的缓蚀性能,尤其抑制点蚀效果很好。     

低频超声波对大豆胰蛋白酶抑制素的处理效果

采用２０ｋＨｚ的低频超声波对大豆胰蛋白酶抑制素（ＳＴＩ）进行了处理。结果表明,超声波对经纯化了的鲍曼－贝尔克抑制素（ＢＢＩ）几乎不起钝化作用,对生豆奶中天然存在的ＳＴＩ的钝化效果要比对从大豆中提取纯化的ＳＴＩ好得多,说明纯化了的ＳＴＩ似对超声处理较稳定;豆奶中大分子蛋白组分１１Ｓ和７Ｓ的存在有助地ＳＴＩ的纯化;低频超声波对生豆奶中的ＢＢＩ似乎有轻微的激活作用;在生豆奶中添加半胱氨酸、亚硫酸钠的胃液     

苯并咪唑类化合物作为碳钢缓蚀剂的研究

通过失质量法、极化曲线法研究了20^#碳钢在含有苯并咪唑类化合物的HCL溶液中的腐蚀行为。结果发现在室温和50℃的条件下，5种苯并咪唑化合物的缓蚀效果都很明显。其中2-对氯苄基苯并咪唑的缓蚀性能最好。
