To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

Finally, the effect of the complete recycling use of distilled effluent on ethanol fermentation was examined in order to save the cost for the treatment of waste distillage and promote cleansing production. Based on the data of 13 circulations, although the average fermentation time needed to be extended to 30~40 hours, over 12.5% ethanol was achieved, at the same time, residual reducing sugar and total sugar were maintained below 0.70% and 0.90%, which indicates that the negative effect of the completely recycling use of waste distillage was limited, and the waste distillage can be completely recycled within the fermentation system.

在此基础上，从减轻废糟液处理负荷，实现清洁生产的需要出发，进行了无种子罐条件下酒精蒸馏废液直接全循环使用的自絮凝颗粒酵母酒精连续发酵实验研究，十三次全循环运行得到的实验数据，与无废液循环的实验结果相比，虽然平均发酵时间略增至30h～40h，但发酵终点酒精浓度仍达到12.5％以上，残还原糖和残总糖分别在0.70％和0.90％以下，说明循环积累物对发酵的影响有限，废糟液直接全循环使用的工艺技术路线可行。

For the fermentation coupled with distillage recycle,every five days,the total backset distillage collected was directly used to mix the corn powder,and the experimental results revealed that the concentrations of ethanol,residual reductive sugar,inorganic phosphate and total solids in the broth were maintained s.

实验结果表明，在稀释速率0.05 h-1，废糟液全循环条件下，装置达到稳定状态后，乙醇、残还原糖、无机磷、无机氮、蛋白和总固型物浓度分别稳定在9.4%、26 g/L、11 g/L、3.36 g/L、0.136 g/L和85 g/L左右；乙醇浓度与对照组相差不大，但残还原糖、无机磷及总固形物在废糟液循环使用的初期出现积累，但随运行时间的延长而趋于稳定，说明对酵母生长和乙醇发酵没有产生明显影响。

Results 3 cases were systic masses under nipple tie 4cases were small multi systic masses in the breast gland 7 cases were mixed echoic masses; 5cases were hypo-echoic masses which maintained breast gland structure and 2 cases were hypoechoic masses.

结果 21例可消退性乳腺肿块，表现为乳头下囊性肿块3例，乳腺内多发性小囊肿4例，乳腺内混合性肿块7例，保持腺体结构的回声减低肿块5例，低回声肿块2例。

Secondly,it is eident that the intensity of up-front therapy cannot-and should not-be maintained for the remainder of the patient's life without compromising his/her quality of life.

第二，在不损害他/她的身体状况的条件下，锋疗法的强度显然不能达到也不能保持住。

S: During incubating of embryonated egg s, the content of protein, amino acid, free amino acid increased gradually, and maintained at a higher lever within the 10 -19 days.

鸡胚蛋在孵化期间，其蛋白质、总氨基酸、游离氨基酸从孵化开始逐渐增加，1 0d～ 1 9d稳定在一个较高的水平，比未孵化的鲜鸡蛋提高 1 %以上，胎水氨基酸从第 7d开始形成，以后含量稳定在 2 。

Result:① In NC group,the levels of plasmic and lymphocytic NO were higher in the morning than those in the afternoon.② The plasmic and lymphocytic NO were significantly decreased in CAD patients then those in NC group (P＜0.01).③The physiological NO curve disappeard in CAD patients.The concentrations were no obvious changes and maintained lower levels in 24 hours.Conclusion:As similar as other endocrinic hormones,the NO secretion was not equal in 24 hours.

结果：①正常人24 h血浆和淋巴细胞中NO分泌呈上午高、下午低的趋势，晨6时最高，下午6时呈低谷，晚10时起又渐升高至早晨；②CAD心绞痛患者血浆和淋巴细胞中NO含量明显低于正常人，其差异具有统计学意义(P＜0.01)；③CAD患者失去了正常的NO生理性分泌曲线，血浆和淋巴细胞中24 h均在较低水平，波动范围不大。

动物体内铁的恒定受到小肠细胞的严密调控，小肠对铁的吸收能力与体内铁贮存量与造血组织需求量有关。

Therefore the commentators seem to have had maintained an old tradition without committing themselves to either eternalism or nihilism or scepticism.

因此这些评论员似乎已经获得了一个古老的传统没有把他们自己交付给永恒主义和虚无主义和怀疑主义。
