     In order to recognize the storage law of methane hydrate in sediments,the filling rates of methane hydrate in water-sediment system were tested by use of a high-pressure hydrate-synthesized device. The influences of different initial generation pressures and temperatures and different sediment pore diameters on the filling rate of methane hydrate in sediments were investigated.

The theoritical results of systems of inbreeding have been discussed in this paper.The general formulae for the heterozygote frequencies.Inbreeding coefficients and the rates of inbreeding for systems of full sib.Alternative parent-offspring and unrestricted Parent-offspring mating involving a single autosomal gene substitution are derived by extrapolation from the change of the heterozygote frequencies of ensuing generations when the population in the initial generation is at equilibrium.These formula are different from what are described in the classical memoirs.By the new ones the evaluation of the parameters Ft.Ht and ΔFt given generation t can be made more easily.The limiting values of Ft and Ht for all of three sys- tems of inbreeding have been verified strictly.The exact limiting value of ΔFt for systems of full sib and alternative parent-offspring mating has been found.It is (2/((1+5~(1/2)))~2) and is the core of the rates of inbreeding of all generations.These rates of inbreeding fluctuate by the core up and down alternately and finally approach to it with the range going down each passing generation.

1.规则近交系统的近交系数及杂合体频率的变化规律在经典文献中被归结为一些世代递推公式,以此描述群体的遗传结构。这里,我们通过研究相继世代杂合体频率的变化与平衡的起始群体基因裂频率的联系,为常体的两等位基因位点,导出表达若干近交系统的杂合体频率,近交系数及近交率变化的通式。2.用本文中的公式可以简单地直接计得任一给定世代 t 的近交系数,杂合体频率及近交率,而不象经典公式需要依赖所求参数在以前世代的值。3.严密地求证了全同胞交配系统,交替型及无限型亲子交配系统的近交系数及杂合体频率的极限值。4.求得了全同胞交配系统及交替型亲子交配系统的近交率的准确极限值,它等于(2/(1+5~(1/2))~2)。5.研究了在全同胞交配系统及交替型亲子交配系统中,近交进程的精细变化。发现各世代的近交率以极限值(2/(1+5~(1/2))~2)为中心,左右摇摆,摆幅逐代减小而趋于该值。

The neutral mutant genes had thd maximum living probability under the same selecting advantage. The dominance or the recessive of the mutant genes appeared as a cushioning effect to selection. The living probability of overdominant mutant gene would increase as its equilibrium gene frequency increased. The living probability of the mutant genes in population had a great catastrophe in initial generations.

在同样的选择有利程度下,中性的突变基因在群体中的生存可能性为最大。突变基因所具有的显性、隐性性质对选择作用有一定的缓冲效果。对于超显性的突变基因,它在群体中的生存可能性有随其平衡基因频率m的增大而增大的趋势。突变基因在群体中的生存概率在早期世代有一个极大的衰减趋势。
