两个新的广义勾股数组 总被引：1，自引：0，他引：1
吴波 《中学数学教学参考》2004,(8):61-61
文[1]介绍了拉氏广义勾股数组，并给出一个新的数组：[18，19，…，34|35，36，…，42]；文[2]谓之[2n 1|n]型；并试图证其唯一性而未果，本文沿用文[2]的方法，又找到2个．设x 1为第一个数，求[n k|n]型广义勾股数，则 相似文献

本文建立了广义Г—环上模的Morita结构,并由此得到了Morita定理;用此定理给出了广义单Artin—Г—环结构定理的另一证明方法。 在文[1]中,陈维新给出了广义Г—环的概念,[2]讨论了本原广义Г—二坏的结构,给出了广义Г—环上的模。在此基础上,本文引进了广Г—环上的投射生成模,模的α—张量积从而建立了Morita结构理论。并应用此理论与[2]中一些结果,给出了左、右Artin单广义Г—环的结构定理的另一证明方法。 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!).
