The research on placenta through modern science show that its important ingredient is immuneglobulin and sneeiyne, which is the anti-aging gene, enzyme, which has high appliance value, and interferon, which protein can reach more than 80%, amino has rich resources、full ranges、and reasonable ration, which fat is less than 10%, and also has rich lecithin, cephalin, lipopolysaccharide, a variety of vitamins and trace elements,in addition, it has transfer factor, protein active factor, collagen element, organic phosphorus compound, amniotic acid and nucleic acid compound and so on.

采用现代科学对羊胎素进行分解，发现其重要成份是免疫球蛋白和延缓衰老基因sneeiyne具有很高应用价值的酶和干扰素，其中蛋白质的含量在80%以上，氨基酸含量丰富，种类齐全，配比合理，脂肪含量小于10%，还含有丰富的卵磷脂，脑磷脂，脂多糖，多种维生素和微量元素，此外，还有转移因子，蛋白质活性因子，胶原蛋白素，有机磷复合物，羊膜酸和核酸化合物等。

Immunoglobulin and anti-aging gene have a high value sneeiyne.sneeiyne enzyme and dry IFN-, in which the protein content of more than 80%, amino acid-rich.full range, areasonable proportion, Less than 10% aft content, but also rich in, cephalin, LPS, a variety of vitamin and trace element Su-, in addition to transfer factor, protein activating factor, collagen Su, organic phosphorus compounds, membrane acid And nucieic acids and other compounds.

免疫球蛋白和延缓衰老基因sneeiyne.sneeiyne是具有很高应用价值的酶和干扰素，其中蛋白质的含量在80%以上，氨基酸含量丰富，种类齐全，配比合理，脂肪含量小于10%，还含有丰富的卵磷脂，脑磷脂，脂多糖，多种维生素和微量元素，此外，还有转移因子，蛋白质活性因子，胶原蛋白素，有机磷复合物，羊膜酸和核酸化合物等。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

Meanwhile, we show some links of Dickson polynomials and difference sets, including some interesting identities.

得到了超卵型线，2-1映射与差集的一些关系，同时，给出了Dickson多项式与差集的一些内在联系，得到了Dickson多项式的原像的一些有趣的等式。

In the microinjection experiment of mouse oocyte,the principle of cell position and attitude adjusting technology was tested.

以小鼠卵母细胞为实验材料，进行了原理性实验研究。

Eleven geographical strains of Eimeria maxima were tested for their ability to induce protection against homologous and heterologous strains, assessed by weight gain, lesion score and reduction in oocyst production.

文章摘要：用平均增重和病变记分或卵囊减少率等为试验指标，对11株巨型艾美耳球虫的免疫原性进行了分析。

The follicular development periods of the Zaocys dhumnades were divided into four stages: oogonium, primary follicle, growing follicle and mature follicle, and the growing follicle was the important phase in the follicular development periods.

乌梢蛇卵泡的生长发育可以分为卵原细胞、初级卵泡、生长卵泡和成熟卵泡等4个时期，其中生长卵泡是卵泡生长发育的重要阶段。

According to the size and shape of cells,nuclei and nucleoli,and to the NPand the vitelline accumulation,the oogenesis can be divided into five phases:oogonium phase,small growth phase,large growth phase,pro- maturation phase and ma...

卵子发生根据卵细胞、细胞核及核仁的大小形态、核质比和卵黄积累情况可分为：1。卵原细胞期：2。小生长期；3。大生长期；4。成熟前期和5。成熟期。卵巢发育则根据第一批卵细胞的发育情况、卵巢长度及颜色分为五期，大致可归纳为三个阶段：5～7月为延缓期；8～11月为对数增长期：12～4月为稳定期。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
