基膜

Since 1962, when Gross and Lapiere discovered the first MMPs-collagenase, man had discovered various of MMPs in succession, where MMP-2 has a strong degradational effect on extracellular matrix, it is secreted bymacrophage, smooth muscle cells and endothelial cells and so on.

自从 1962年 Gross和 Lapiere发现第一种基质金属蛋白酶一胶原酶以来，人类陆续发现了很多种基质金属蛋白酶，其中的MMP—2对细胞外基质具有极强的降解作用，它由巨噬细胞、平滑肌细胞以及内皮细胞等分泌，在动脉粥样硬化斑块中憎多时降解纤维帽及基底膜的胶原等基质成分，是使纤维帽变薄及加速动脉粥样硬化的重要因素之一。

AFM, EPMA (Electronic Probe Measurement Analysis) and SEM were used to study the mechanism of bisquats named MDOPD N Metronidazole N (Dodecane 3 Oxal 1,5 Pentanedilamonium Dichloride against Total Growth Bacteria in the culture medium.

研究结果表明：MDOPD能够在培养基中的碳钢金属表面优先吸附，形成完整致密的有机吸附膜，使细菌新陈代谢产物难以到达金属基体表面；同时，MDOPD使生物膜的沉积变得疏松，氧浓差腐蚀和膜下硫酸盐还原菌引起的腐蚀都受到有效的抑制

Because of the high diffusivity and solubility of oxygen in Ti〓Al, once the oxidation layer loss its protection, oxygen can easily enter into the alloy and thus considerable oxygen contaminated region is formed, which would embrittle Ti〓Al alloys and seriously decrease their thermal stability and high temperature properties.

氧在Ti〓Al基合金中具有较高的固溶度，当表层氧化膜缺乏保护性时，氧得以在合金基体表面部分形成厚度可观的氧污染层，使本身塑性就较差的Ti〓Al基合金脆化，从而严重影响Ti〓Al基合金的热稳定性和高温力学性能。

Low temperature ordering of FePt thin films has been achieved by using a thin equiatomic AuCu underlayer.

提出并利用相干生长的多层膜中有序－无序转变过程的彼此关联作用，借助AuCu缓冲层的低温有序化，降低FePt薄膜的有序转变温度200℃以上，为FePt薄膜的低温有序化开劈了一条新途径；制备多层膜，退火形成有序相FePt纳米颗粒分散在Ag基体的复合结构，比FePt/Ag共溅射或合金多层膜方法的退火温度明显降低；通过缓冲层Ta控制FePt的粗糙度和晶界密度，同时界面附近Ta、Pt发生化学反应，两者共同促进薄膜内Pt原子的有效迁移，从而加速FePt有序化；进一步，在Ta和FePt之间插入Bi薄层，强化Ta、Pt的扩散，在更低温度下形成高矫顽力的有序化FePt薄膜且FePt晶粒之间交换作用大大减弱；发现MgO薄膜作底层，可控制与MgO晶粒尺寸大致相当的临界厚度以下的FePt有序化薄膜的（001）取向，同时，MgO和FePt的相对厚度显著影响（001）取向FePt的有序化。

The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.
