We study contributions of the pion meson and spatial component of the omega meson in the odd-A carbon isotopes. The pion and spatial omega provide small attractions in odd-A nuclei, giving rise to considerable influences on the single-particle energies rather than the bulk properties such as total binding energies, and root-mean-square (rms) radii. The ±? (spin) splittings, arising from the spatial omega, are large in 11C and 13C and drop as the isospin rises in odd-A carbon isotopes. As an isovector, the pion can shift slightly the relative potential depth of neutron and proton, contrary to the role of the rho meson. There is a general trend that both the pion and spatial omega fields reduce with the rise of isospin in the isotopic chain. From the normal nucleus to halo nucleus, an abnormal drop of the pion or spatial omega field may occur, as can be seen in 19C, 15C, and 21C.

试析正始之音对建安诗风的继承关系

江苏广播电视大学学报 2004年第5期15卷 44-46页

作者：王士君菏泽学院山东菏泽274000

中国诗歌,从建安到正始,诗风虽然出现了明显的变化,但二者又非截然不同,而是有着内在的联系。正始诗坛依旧回响着建安的慷慨之音;并且沿着建安诗歌的抒情传统,向着个性化、抒情化的方向进一步发展;建安诗歌的悲凉演变为正始诗的忧生之嗟。

借助于粒子数算符的本征态和坐标算符函数的本征方程,把坐标算符的本征矢〈f(x)表示为一个算符对坐标本征矢〈x的作用.由此,把不对称的坐标投影算符转换为对称的坐标投影算符,再利用坐标本征矢的完备性,给出不对称坐标投影算符的积分.

The crystallization behavior of PEOs with molecular weight of 1 Ok and 200k as well as their blends was studied in details. The results show that the lower molecular weight PEO crystallizes with faster crystallization rate as judged from a shorter time for completing the crystallization. On the other hand, the higher molecular weight PEO crystallizes at relatively higher temperature, indicating an early start of crystallization compared with the lower molecular weight one. The blends of these two PEOs with different blend ratios always cocrystallize during the cooling processes. It is confirmed that mixing of the 10k PEO with the 200k one is in favor of the crystallization of the system. This is not only demonstrated by the early start of the crystallization at higher crystallization temperature, and also a faster crystal growth of the blend with respect to the 200k PEO. The crystallization of the blends at higher temperature is caused by an early start of nucleation and an increment of nucleus density. This may originate from the density fluctuation of the blend and a reduction in energy barrier for nucleation. Moreover, it is found that the crystallinity of the 1 Ok PEO rich blends increases with increasing concentration of the 10k PEO. This is caused by the solvent effect of the 10k PEO toward the 200k PEO. On the other hand, the crystallinity of the 30/70 （10k/200k） PEO blend is decreased a little bit. This may be a balanced result of the improved crystallization of the 200k PEO at the expense of the high crystallization ability of the 1 Ok PEO.

对输华胡椒种苗传带有害生物的潜在危害开展风险分析和评估,为检疫部门制定风险管理策略提供理论依据。通过查阅国内外相关研究进展,确定境外输华胡椒中可能传带的有害生物共有127种,包括真菌27种、细菌6种、线虫24种、昆虫68种、杂草2种。根据在中国的分布情况(未分布或分布未广)、是否官方管制、随胡椒种苗携带的可能性进行评估,确定需要进一步评估的潜在检疫性有害生物14种,包括真菌5种,细菌2种,线虫2种,昆虫5种。从入境、定殖、扩散可能性、经济影响和多指标综合评价方面对这14种潜在的检疫性有害生物进行定性和定量分析,结果表明,极高风险有害生物4种、高风险有害生物9种、中风险有害生物1种。最终确定有害红皮孔菌(Pyrrhoderma noxium)等14种有害生物为输华胡椒种苗需关注的检疫性有害生物,并提出风险管理方案。
