Nor did they spat over trivia. If the Sina list is like the star-shining sky, there are uncountable grass-root bloggers like glamorous, kaleidoscopic grasslands. When a star shoot across the sky, there will be a big focus (metaphorically the huge blog clicks ) among many people who look up into the sky, but over time we could have sore necks, and we feel uncomfortable in our eyes after meteorites vanish into nothing. When we overlook a small garden or unknown grassland, Obscure as they might be and it might be too small for all people to see, but what we can get there is the tranquility, the aroma of the flowers, the singing of birds and the fresh air that makes us feel our oats.

如果说新浪博客百强排行榜是星光灿烂的天空，那么，成千上万默默无名的草根博主就是繁花似锦、茂草如毯的大地，星空中某颗瑰丽璀璨的恒星、或某粒骤然划过的流星，固然会引来众目仰望，但恒星看多了，脖子会疼，流星看过了，眼睛会酸；大地上某个普通的花园、某片无名的草坪，虽然一时难容太多人观赏，但花香养鼻，草色养眼，曲径通幽，健腿益心。

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.

Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.
