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.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。

Any of various insects of the family Gryllidae, having long antennae and legs adapted for leaping.

蟋蟀任一种蟋蟀科的昆虫，有擅长跳跃的长触角和腿。

Three dimensional (3D) honeycomb-like porous structures made up of nanoslices of hydroxy cupric phosphate heptahydrate Cu8(PO3OH2(PO4)4·7H2O single crystals were constructed by a facile assistant surface oxidation technology. The pore size of the 3D structure ranges from hundreds of nanometers to two micrometers, and the thickness of the two dimensional (2D) nanoslices is about 50~100 nm. The wettability of the porous surfaces was transformed from superhydrophilic to superhydrophobic by chemical modification with octadecanethiol or PDES.

相对于硬脂酸修饰表面，氟硅烷修饰表面对水滴具有更低的接触角滞后和较低的黏着，这可能是因为氟硅烷比硬脂酸具有更低的表面自由能所致。2、利用酸辅助的表面氧化技术制备了由Cu8(PO3OH)2(PO4)4·7H2O单晶组成的三维蜂巢状多孔结构，孔尺寸约为几百纳米到2微米，二维的纳米片厚度为50~100 nm。

Antennal morphology and sensilla of the green plant bug, Lygus lucorum Meyer-Dür (Heteroptera: Miridae), were studied using scanning electron microscopy.

利用扫描电镜对绿盲蝽雌雄成虫的触角形态和感器进行了观察。

The contact angles of water and hexadecane on the resulting ultra thin film were measured so as to investigate the hydrophobic hydrophilic properties of the film.

结果表明：所制备的自组装膜的表面自由能很低，具有很好的疏水-疏油性，其对水的接触角高达 1 1 0°；二甲基-γ-全氟辛酰氧丙基硅烷组装膜可以降低基片的摩擦系数，而且在较低负荷下具有很好的耐磨性
