By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1~N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征,研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪;N1层属于低孔、特低渗储层,孔隙类型以原生、次生粒间溶孔为主;分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用;进行了储层评价与有利相带预测,将储层分为三类并划分了有利区带、较有利区带,认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带,储层以Ⅰ、Ⅱ类为主。

Results indicated that introducing some ring-structure into UF molecule during the synthesis could efficiently improve the water resistance of UF resin. The Uron ring would form if reaction temperature was more than 75 degrees C, and the higher Uron content was obtained at pH 8 and 85 degrees C in the absence of catalyst when the reaction time was long enough.
结果表明:通过在脲醛树脂合成中引入Uron环等环状结构物质能够有效提高脲醛树脂胶黏剂的耐水性;当反应温度高于75℃时,反应产物都生成了一定量的Uron环物质;在pH值为8左右、温度控制在85℃、不使用催化剂、尽可能延长反应时间的条件下,尿素与甲醛成环化反应生成的Uron相对值最多。

Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.
乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物,而利用不同标记来定量骨质转换形态,可以评估乳癌骨骼转移的变化,而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物,骨特殊碱性磷酸酵素是一种同形酵素,位於成骨细胞的外膜且在骨骼形成时释放至血液中,利用此两种生化标记,可以来预测乳癌转移至骨骼的转换情形。

The primary cause of the acquired platelet defect is thought to be activation and release of alpha granules during extracorporeal circulation. Before CPB PRP was prepared by obtaining the required amount of patient's whole blood by autologous plateletpheresis. PRP could be reinfused after operation in order to save the function and quantities of the platelets. On the other hand PRP could be made into autologous platelet gel. APG contains supraphysiologic amounts of growth factors and has adequate tensile strength and adhesive ability.
CPB前,利用自体血小板分离技术可将部分血小板从患者全血中分离出来制成富血小板血浆(Platelet-rich plasma PRP),PRP可在术后回输,以达到血小板数量和功能的双重保护,另一方面可将PRP制备成自体血小板胶,APG中含有丰富的生长因子,并且具有足够的抗张强度和粘性,因此可起到术中止血,封闭伤口,促进胸骨及伤口愈合的作用。
