Chapter 1: The reactions of methylenecyclopropanes with phenylsulfenyl chloride or phenylselenyl chloride give cyclobutene derivatives along with ring-opened products in good total yields at 0 °C in various solvents. The reactions of methylenecyclopropanes with diphenyl diselenide give the di-phenylselenyl substituted ring-opening products which can be transformed to 2,5-dihydrofuran derivatives under the oxidation with hydrogen peroxide at room temperature.

在第一章中，我们发现亚甲基环丙烷类化合物在0℃时即可很快与苯硫氯或苯硒氯发生反应生成取代环丁烯类化合物和正常的开环产物；而与二苯基二硒的反应则需加热到150℃以上才能进行反应，生成的二苯硒基开环产物在双氧水氧化下可以转化为取代二氢呋喃类化合物。

This dissertation is mainly focused on the reactivity of methylenecyclopropanes and comprises six parts. 1 The reactions of methylenecyclopropanes with phenylsulfenyl chloride, phenylselenyl chloride and diphenyl diselenide; 2 The coupling reactions of the ring-opening products derivated from methylenecyclopropanes; 3 The palladium-catalyzed ring-enlargement of mono-aryl group substituted methylenecyclopropanes to cyclobutenes. 4 The gold-catalyzed domino ring-opening and ring-closing hydroamination of methylenecyclopropanes with sulfonamides; 5 The Lewis acid-catalyzed reactions of mono-aryl group substituted methylenecyclopropanes with diethyl ketomalonate in the presence of water; 6 The iodobenzene diacetate mediated novel 1,3-dipolar cycloaddition of methylenecyclopropanes, vinylidenecyclopropanes, and methylenecyclobutane with phthalhydrazine.

This is understandable. If many shopping bags in a recession looks bad, bricks and mortar retail - huge out-of-town shopping centres, retail emporia that insist on leaving their doors open even in winter and grocery stores full of the most inefficient freezers - look terrible during an ecological emergency.

这是可以理解的，如果在经济衰退时期看到很多购物袋，这是相当不好的，那些远离购物中心的有石块和水泥构成的零售商场，那些零售中心坚持在冬天仍然开着门，在生态危机的时候仍然开着那些里效率的冰箱是十分可怕的。

Therefore, the design practice, simulation: design background Quanzhou to spend for the elements of Erythrina flower to bloom in its design for the exterior design, its color is red color, reminiscent of the total flowers Citong "The Book of Songs "Shuo people in the, Comehope of a better attitude," Amidst the southern Wenbo Chen,Citong new flowers."

所以，本设计方案练习，模拟：设计背景为泉州市，以市花刺桐花为元素，以它的盛开造型为外观设计，色调也是它的红色颜色，刺桐花开总让人想起《诗经》里的硕人巧笑倩兮，美目盼兮的美好姿态，&南国清和烟雨辰，刺桐夹道花开新&。

So the opening of Foochow has little influence on the hinterland of Min River valley.

文中指出，开埠后在闽江流域形成了新兴商埠与传统农业并存、手工业鲜有改良、商业鲜有实质性发展的状况，因此开埠对闽江流域内地的影响甚低。

It is pointed out that the new-built commercial ports and traditional agriculture co-exist, the handicraft industry seldom changed and the business seldom developed in Min River valley after the opening of Foochow.

在第五章中，我们主要依靠清代以来的方志，详细考察了开埠前后腹地地区各县的农业、手工业、商业和农家经济状况的变化，以探求开埠对内地的影响。

Chapter Five explores in detail the changes in agriculture, handicraft industry ,business and peoples subsistence in the hinterland before and after the opening of Foochow by using the existent chorographyby since Qing Dynasty and investigates the influence of the opening on its hinterland.
