研究表明：①岩石中绿泥石主要呈脉状、黑云母假象或团块状等产出，具有蠕虫状、叶片状等形貌特征；②绿泥石的Fe/Si图解显示201和361铀矿床中绿泥石主要为铁镁绿泥石和蠕绿泥石，少数属密绿泥石；③根据Battaglia提出的经验方程式计算了201和361铀矿床绿泥石的形成温度变化于179~276℃之间，且主要介于230~260℃之间；④绿泥石主要形成于还原环境，其主要的形成机制是溶解－沉淀和溶解－迁移－沉淀。

3 Ma: from the basalt beds under the Jingangshan bed of the Yixian Formation, and 120.3 Ma: from the lower part of the Jiufotang Formation,showing an age of late Early Aptian.

122.3Ma：义县组金刚山层之下的玄武岩，120.3Ma：九佛堂组下部，表明其时代为早阿普丁阶晚期。

Methods S. epidermidis atlE gene expression level at different phases was detected by RT-PCR, and the accumulation of extracellular DNA at different phases was assessed by spectrophotometric measurements of light absorbance by DNA; DNase Ⅰ was used to study the function of extracellular DNA in biofilm formation and primary attachment. The effects of atlE gene deletion on initial adherent capacity, biofilm formation and extracellular DNA release were studied by construction of atlE deletion mutant via homologous recombination.

采用RT-PCR法检测表皮葡萄球菌atZE基因在不同时期的表达水平，用紫外分光光度计检测DNA的方法检测了相应时期的胞外DNA的释放量，并用DNA酶研究表皮葡萄球菌胞外DNA在生物膜形成和起始黏附中的作用；采用ρBT2质粒同源重组敲除的方法构建了表皮葡萄球菌1457的atlE基因突变株，研究atlE基因敲除突变对起始黏附能力、生物膜形成及胞外DNA释放能力的影响。

Downhole throttling technology is to adjust downhole pressure through installing the throttle valve in an appropriate position on the tube. The gas flowing through the throttle valve is heated up by the geotherm and the conditions of gas hydrate formation are changed, so as to effectively prevent gas hydrate formation, decrease transportation pipeline pressure, eliminate attemperator, and reduce the cost of gas production.

井下节流技术将井下节流器置于油管某一适当位置来实现井筒节流降压，并充分利用地热对油管内流体加热，使节流后气流温度高于节流后压力条件下的水合物形成初始温度，从而达到降低地面管线压力，取消地面加热保温装置、降低气井开采成本的目的。

在羟基化反应液中加入亚硫酸氢钠可以抑制对苯醌和残留催化剂对苯二酚氧化缩合生成焦油的催化作用，从而减少了反应液中苯二酚的生焦反应。

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.

以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄，使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高，从而易导致CA膜形成双连续结构；温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近，均相区减小；ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制，而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。
