Our study includes four aspects. In the first aspect we study several important conditions of porcine oocytes maturation in vitro and oocytes cleavage after parthenogenetic activation and found mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15% PFF+0.57mMcysteine is a good culture condition .When the Cocs are cultured in it ,the maturation rate and oocytes cleavage rate are higher than those of foreign covered. Our result are (86.7±3.35)% and (86.3±4.16)% and the highest report of foreign is(85.7±4.1)%.In the second aspect we study the effect of different chemical activations on development of porcine parthennogenetic embryo and found two best activation method. The first one is that putting the maturation MII oocytes in the 20μmol/L ionomycin for 30 minutes and then putting them in the NCSU-23 condition containing 5μg/mICB and 5mM/L6-DMAP for 3.5 hours, the oocytes cleavage rate and morulae/blastocysts development rate are (76.7±7.6)% and (37.1±6.4)%.The second one is that putting the maturation MII oocytes in the 200μM/L Thimerosal for 20 minutes and then putting them in the NCSU-23 condition containing 8mM DTT for 30 minutes

Results: The cs rate is 29.90%, and the first cause of it is due to fetal distress (13.50%); the second is macrosomia (6.11%). Among those multiparas who delivered the second babies in years later the incidence of relative cephalopelvic disproportion is much higher.

结果：经产妇的剖宫产率为29.90%，其手术指征中首位是胎儿宫内窘迫，占13.50%；其次是巨大儿，占6.11%；相隔10年以上再次分娩的经产妇更易发生相对性头盆不称。

If second fragment's offset is less than 800, that means the second fragment overlaps the first fragment.

如果第二个片段的偏移量低于800，这意味着第二个片段重叠第一片段。

Its total exports value in 2007 reached 1.218 trillion U.S. dollars, which exceeded that of the United States, and was second only to Germany as the second largest exporting country.
