H型群上次Laplace算子相邻特征值之差的估计

目的研究H型群G上次Laplace算子的D irichlet特征值问题。方法建立H型群G上向量场的性质,结合欧氏空间的经典方法。结果给出了H型群G上次Laplace算子D irichlet特征值问题相邻特征值之差的估计,此结果与区域的几何和G的Lie代数的第二层的维数无关。结论把欧氏空间上的结论推广到了H型群上,并在H型群情形下有所深化。     

樊家川油田河流相储层砂体沉积模式

目的建立樊家川油田河流相储层砂体的沉积模式。方法在油层沉积体系分析的基础上,依据地面露头及井下岩心精细描述,并通过井网砂体追踪对比,研究了不同类型河流相储层砂体的非均质特征。结果建立了辫状河砂体“泛连通体”、曲流河砂体“半连通体”的储层砂体沉积模式。结论辫状河砂体形成“拼合板状”储层结构形式,曲流河砂体形成“迷宫状”储层结构形式。

A new type of triploid crucian crap?red crucian carp (♀)×allotetraploid (♂)

A new type of triploid hybrids (TC) was produced by crossing red crucian carp (♀) with allotetraploid hybrids (♂). This type of triploids with no barbel was spindle-shaped and gray in color. Compared with their parents, some data of the morphological traits in the triploid hybrids were intermediate to those of their parents, and some were beyond their parents with heterozygous traits. Under the same culture conditions, the growth rate of the new type triploids was faster than their maternal red crucian carp (RC). The gonadal development of triploids was obviously slower than that of diploids, and the germ cells in them were degenerated. Compared with another type of triploids produced by Japanese crucian carp (♀) with allotetraploid hybrids (♂), the new type triploids not only kept faster growth rate and sterility, but also had no barbel that was similar to the common carp. The absence of the barbel in the new type of triploids has the important significance in both the inheritance and fish breeding.
