The results indicated, that the curves of hatching rate and normal diploid larva output showed a single peak, with the highest point at 3.4 τ0, corresponding to metaphase of the first mitotic division, the results were obtained irrespective of the different pre-treatment water temperatures, thus confirming the veracity of measuring heat-shock timing by τ0 and the wild applicability of this method in cyprinid and also suggesting a new way to the operations of induced gynogenesis in related fish.

结果提示了以τ0单位度量热休克处理时机的准确性以及该优化方法在鲤科鱼类雌核诱导操作中的通用性，从而为相关鱼类的雌核发育操作提供了有价值的资料。

Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。

The study of nucleation agent contents indicates that different contents have different effect on glass devitrification degrees, crystal phase amounts and crystal sizes.

不同的晶核剂有不同的作用机理，本文从不同角度对FeS和TiO2的成核机理做了的分析。

Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months. The changes became more severe with the prolongation of DU ingestion. Such changes occurred in filial rats (F1) after DC ingestion for 5 months. In the medium and high dose F0 groups, it was observed that a little atrophy of kidney glomerulus, hyperplasia of interstitial tissue after DC ingestion for 14 months, and kidney glomerulus fibrosis happened after DC ingestion for 20 months, such changes occurred in filial rats (F1) after DC ingestion for 5 months In the medium and high dose F0 groups, splenic germinal center and periarterial lymphatic sheaths were hyperplasia , companies with lymphopoiesis after DC ingestion for 7 months, splenic white pulp became more small and sparse after DC ingestion for 20 months.

结果 F0代的中、高剂量组大鼠摄入贫铀14个月后可见雄性的精曲小管萎缩，管壁增厚呈空虚网状，生精细胞层次减少，间质细胞增生，但仍见有精子生成；高剂量组可见到精子呈异型性改变，细胞核浓缩深染，且随着摄入时间延长改变愈趋明显；F1代大鼠摄入贫铀5个月后就有上述改变且更为严重。F0代中、高剂量组大鼠摄入贫铀14个月后肾小球轻度萎缩，间质增生明显，20个月时肾小球萎缩纤维化；F1代大鼠摄入贫铀5个月后就有上述改变。F0代中、高剂量组摄入贫铀7个月时脾脏生发中心和淋巴鞘增生，淋巴母细胞增生活跃，20个月时脾小体减少，生发中心稀疏；F1代大鼠摄入贫铀早期和晚期有类似改变。F0和F1代高剂量组摄入贫铀早期肝脏有炎症细胞浸润，晚期骨髓有核细胞减少，脂肪细胞增加。

An attractive hypothesis has been a semiconservative mechanism in which parental histones are combined with newly synthesized histones within the same core nucleosome.

一个有吸引力的假说是半保留的机制，在这一机制中，亲本的组蛋白和新合成的组蛋白共存于同一核小体核心中。

Double fluorescent immunohistochemical staining revealed close apposition of VIP-, PACAP-, and vasopressin-immunoreactive terminals with tyrosine hydroxylase-ir neurons within the dorsomedial arcuate nucleus. We were then of interest to learn from where VIP-, PACAP- and AVP-containing neurons that project to the ARN originate.

经由双重免疫萤光染色法，可以在弓状核的背中区，具酪胺酸羟化酶免疫活性的细胞旁，发现有VIP、PACAP及血管加压素免疫活性的神经末稍的分布及并置，显示确有VIP，PACAP及AVP之神经元投射至弓状核。

GnRH-ir fibers distribute in the various brain region from the olfactory bulb to the cerebellum. They are especially abundant in the hypothalamus, the preoptic area and the ventral telecephalon. The immunopositive reaction in precocious fish is evidently stronger than that in unprecocious fish, and there is only very weak reaction in the gonadal undeveloped fish. The differences are most obvious in the hypothalamus, but not in other areas.

性早熟大黄鱼的神经内分泌细胞对GnRH抗血清的免疫阳性反应明显，无论在细胞的数量和免疫强度都比未早熟鱼多和强，在性腺尚未发育的幼鱼脑中仅有弱的免疫阳性，这种差异在下丘脑外侧结节核及视前核处最为明显，在其它GnRH阳性部位则差异不显著。

杏仁核的局部区域脑血流或葡萄糖代率的上升和抑郁症状有联系，悲伤紧张性的不断增加和左侧杏仁核及左侧颞极的激活增加相联系。

In addition, the momentum dependence of the nuclear mean field potential has been shown for the first time to be important for isospin diffusion in HIC''s and a explicit expression for the density dependence of the symmetry energy has been obtained by fitting the experimental data.
