They spread throughout Africa over the following 50,000 years or so: around 100-80,000 years ago, three main lines of Homo sapiens diverged, bearers of mitochondrial haplogroup L1 / A colonizing Southern Africa (the ancestors of the Khoisan/Capoid peoples), bearers of haplogroup L2 / B settling Central and West Africa (the ancestors of Niger-Congo and Nilo-Saharan speaking peoples), while the bearers of haplogroup L3 remained in East Africa.

Results showed that the PMC meiosis of autotetraploid was similar to the diploid except some particularities. In metaphase Ⅰ, multivalent, quadrivalent, trivalent, bivalent and univalent were observed and some of the chromosomes were found not to rank on the metaphase plate and so did in metaphase Ⅱ cells. In anaphase Ⅰ and anaphase Ⅱ cells, there were lagging chromosomes, chromosome bridge and fragment. During anaphase Ⅱ and telophase Ⅱ, chromosome segregation was not synchronous or equal. At tetrad stage, dyad, triad, tetrad with micronucleus and polyad appeared.

That indicates there might be differences in respiring and feeding between diploid and triploid Pacific oysters.

二、对四倍体牡蛎精子的透射电镜观察结果表明，四倍体太平洋牡蛎的精子的形态结构与其二倍体基本相同，都是由头部、中段和鞭毛三个部分组成。

5.9号三体的花粉活力显著低于二倍体；2号、7号三体的花粉活力极显著低于二倍体；7号三体的花粉活力最低。

Methyltrichlorosilicane and phenyltrichlorosilicane are applied for the synthesization of the ladderlike polymethylsilsesquioxane and ladderlike polyphenylsilsesquioxane.

选用甲基三氯硅烷和苯基三氯硅烷为主要原料合成了梯形聚甲基倍半硅氧烷和梯形聚苯基倍半硅氧烷。

With this method the copper plating graphite powder was made up in 50% copper content .The silver- copper plating graphite composite was prepared while the silver- copper-graphite composite and the silver-graphite composite were also made up together .The mechanical and electric characteristics of the three kinds of composites were tested and it was found that the copper plating graphite powder can only optimize the properties of the silver matrix composite under the high content of the graphite ,the conductivity and the mechanical property was improved and the material could take higher current in the same carbon content .At 20% carbon content, the resistivity of Ag-graphite composite was 1.67 times as high as that of silver- copper plating graphite composite, the resistivity of Ag-Cu-graphite composite was 3.23 times as high as that of silver- copper plating graphite composite. The bending strength of silver-copper plating graphite composite was 2.17 times as high as that of silver- copper-graphite composite, and the bending strength was 2.11 times as high as that of silver- copper-graphite composite. The wearability of silver- copper plating graphite composite was also enhanced greatly at high carbon content.

利用该方法制备了50%铜含量的镀铜石墨粉，然后进一步制备了一系列相同碳含量的银-石墨复合材料、银-铜-石墨复合材料、银-镀铜石墨复合材料，对三种材料的机械、电气性能进行了综合对比，发现在低碳含量时镀铜石墨粉不能改善复合材料的上述主要性能，而在中高碳含量时则能明显优化复合材料的整体性能，提高了复合材料的电导率，使复合材料在中高碳含量时既具有较高的耐磨性同时也能负载较大的电流，复合材料的机械性能也因镀铜石墨粉的加入而大幅提高，20%碳含量时，银-石墨复合材料的电阻率是银-镀铜石墨复合材料的1.67倍，银-铜-石墨复合材料的电阻率为银-镀铜石墨复合材料的3.23倍，银-镀铜石墨复合材料抗弯强度是银-铜-石墨复合材料的2.17倍，是银-石墨复合材料的2.11倍，同时，在实验给定的条件下，中高碳含量时银-镀铜石墨复合材料的机械磨损耐磨性和通电磨损耐磨性都得以显著提高，银-镀铜石墨复合材料在实验时的接触电压降也更为稳定。
