为探究大直径钻孔桩在成孔过程中孔内泥浆性能的变化及对施工质量的影响,以龙泉市大直径钻孔桩的施工为背景,根据对现场泥浆性能的测量结果及时制定应对措施,为大直径钻孔桩的施工提供参考。结果表明,在成孔过程中泥浆中的砂子向孔底沉淀,使孔内泥浆比重逐渐减小,含砂率与比重的拟合指数R2在0.858~0.987之间。泥浆含砂率的降低导致其黏度下降,在循环使用期间,泥浆中的胶体部分逐渐被消耗,导致清孔时泥浆携砂性能下降。终孔后,泥浆含砂率的变化直接影响孔底沉渣厚度,孔底泥浆含渣率最高可达86%。采用气举反循环方式协同除砂机进行清孔,1.5~2 h可完成清孔;清孔完毕后应立即浇灌混凝土,避免孔底再次淤积沉渣。

采用Bligh-Dyer法提取坛紫菜中的总脂,甲酯化处理后,用GC-MS联用仪对采自不同地域、不同品系以及不同采收期的坛紫菜进行脂肪酸定性定量分析。结果表明,在紫菜脂肪酸组成中,多不饱和脂肪酸（PUFA）所占比例最高,饱和脂肪酸（SFA）次之,单不饱和脂肪酸（MUFA）最低。其中SFA以C16：0为主,占26%~33%,MUFA中主要为C18：1（n-9）,PUFA中含量最高的是C20：5（n-3）（EPA）,其相对百分含量占总脂肪酸含量的32%~46%。对同一品系不同采收期的坛紫菜,随采集次数的增加C16：0相对百分含量逐渐减少,PUFA中EPA随采集次数的递增含量明显增加,而C20：4（n-6）的相对百分含量则逐渐减少;不同海域同一采收期的坛紫菜,浙江海域紫菜的多不饱和脂肪酸含量比福建海域较高;对于同一海域不同品系的坛紫菜,头水中多不饱和脂肪酸含量浙东1号要高于申福2号,特别是EPA含量,其他阶段差异不大。通过对坛紫菜中脂肪酸组成及含量变化,可以更好地为坛紫菜品质分析及坛紫菜健康养殖及食品开发提供参考依据。

水银洞金矿上二叠统龙潭组一段(P_3l^1)中矿体主要为生产探矿中新发现,地质勘探中未发现该类金矿体的大规模存在;主要以构造控制的白云石石英脉粉砂质粘土岩型为主,灰岩类及白云石化钙质砂岩类含金矿体为辅,白云石石英脉粘土岩型矿体是以品位高、厚度薄、稳定为特征,该矿体受灰家堡背斜轴附近的东西走向隐伏逆冲断层控制,主要分布于F_(301)断层上下盘,含金热液沿东西走向隐伏逆冲断层向上运移(刘建中.2003)、再向有利的层间滑动及北东向陡倾斜次级隐伏逆冲断裂构造富集成矿,东西走向隐伏逆冲断层是导矿构造又是容矿构造,其上盘层间白云石英脉为明显找矿标志,对灰家堡背斜深部找矿及和生产具有一定的指导有意义。

目的探讨低氧对蠕虫和细菌混合感染小鼠肠道黏膜免疫功能的影响。方法以十二指肠寄生鼠多形螺旋线虫和感染肠道鼠枸橼酸杆菌的小鼠为模型,分别在海拔2 260 m(大气压582mm Hg,PO2121.6mm Hg)和海拔5 000 m(大气压405mm Hg,PO284.7mm Hg)条件下建立单纯蠕虫感染及蠕虫和细菌混合感染模型,分别观察小鼠体重、小肠长度及十二指肠形态学变化;同时检测寄生在十二指肠的鼠多形螺旋线虫数目和各组小鼠血清IgE、IgG1抗体浓度。结果 (1)低氧组体重明显降低,低氧混合感染组降低尤为显著。(2)在低氧和蠕虫感染条件下小肠长度均增加。(3)低氧混合感染时,寄生在十二指肠的鼠多形螺旋线虫数目明显增多。(4)蠕虫感染时血清IgE、IgG1浓度均升高,但在低氧条件下小鼠IgE、IgG1抗体浓度有所降低。(5)十二指肠组织形态:低氧混合感染组有明显的黏膜破损和严重的上皮细胞脱落及炎细胞浸润。结论低氧会降低血清IgE、IgG1抗体浓度,影响肠道黏膜免疫功能;低氧可加重鼠多形螺旋线虫和肠道鼠枸橼酸杆菌混合感染导致的肠道病变。
