Percent and 21. 4 percent respectively. F1 plants of R01 self-cross also present diverse colors such as white, pink, red, nacarat/saffron, dark yellow, yellow and so on, And the pink and the nacarat/saffron plants have the highest proportions, 50.6 percent and 31. 4 percent, respectively. The wide segregation chromatogram of self-cross progeny implies that these two varieties themselves contain the abundant genetic polymorphism. The ISSR genetic diversity analysis and the principle factor analysis were performed using 49 plants of RP1 self-cross progeny population and 123 plants of R01 self-cross progeny population.

RP1及R01的遗传多样性最高，这从自交一代的表观性状及ISSR的遗传变异可以得到证实，如RP1自交，F1代花色有白色、粉色、玫瑰红、深红色、桔红/桔黄、黄色，黄红复色等，其中以粉色及桔红/桔黄色占的比例最大（分别占61.2％，21.4％）；R01自交，Fl代花色有白色、粉色、红色、桔红//桔黄、深黄色，黄色，其中以粉色及桔红/桔黄色占的比例最大（分别占50.6％，31.4％），较广的自交分离色谱，表明两个品系自身存在丰富的遗传多态性。

The results show that ordered phases precipitated and formed a pseudobinary system; precipitated earlier than g phase by a congruent ordering + spinodal decomposition mechanism and thus produced a nonstoicheometric ordered phase, then the nonstoicheometric g phase precipitated by a non--classical nucleation and growth mechanism at the boundaries of phases, meanwhile, both of them transformed to stoicheometric ordered phases.

研究发现该合金沉淀过程中，析出D022结构的(Ni3V)相和L12结构的Ni3Al相，二者构成伪二元系；相先于相析出，相的沉淀机制为等成分有序化+失稳分解，相在相的相界处非经典形核，二者均先形成非化学计量比有序相，之后向化学计量比有序相转变；随Al浓度增加，相析出变慢，所占比例减少，而相反之，析出越来越早且所占比例增加。

The experiment obtains clone pig HUMMLC2B gene (GenBank logs onto date: DQ533994), use PCR-RFLP technology, analysed HUMMLC2B gene the 1st embedded child medium Msp Ⅰ is enzymatic cut much condition (T613C) is in distributinging; analysed the much condition sex in 7 breed pig 5 many condition sex and 36 long white pigs, groups 104 pigs and grow to be mixed in vain 5, the result makes clear, the scale that waits for a gene and B to wait for a gene frequency except the A in long white pig in detected swinery is 1 ∶ 2 outside, of the others all take absolutely advantage for a gene such as B, and a gene such as A is pure close individual detect in long white pig only.

Macrophanerophytes such as pine and cedar are more and occupie greater percentage to from bottom to top, which are affected by clime and geography and human avtivity. Because people pay more attention to Macrophanerophytes and less to shrub and herbge plants, ecology of the forest is unbalance and benefit is low.

在整个沉积物柱的孢粉组合中，松、杉等大型乔木始终占有很高的比例，而且越到上部比例越大，这除了受滇中地区气候地理因素的影响外，可能还有人为的原因，人们在保护森林资源和植树造林过程中往往只是注重了大型的乔木而忽视了灌木和草本植物，从而使森林生态失衡，生态效益低下。
