1前言近年来，我国的核电事业发展较快，国家核电发展的导向是走核电设备国产化的产业路线，需要进行设备的自主化设计和建造，这就需要建立相应的质量保证机制。

The agreement establishes a process to collaborate with each other and with the International Atomic Energy Agency on export controls, international nuclear safeguards, protection of nuclear materials and facilities, nuclear emergency management and radioactive source security, it said.

这一协议为双方的合作，以及国际原子能组织控制下的核能出口，国际核安全、核原料的安全和保护、核问题紧急的处理、放射性核能的安全问题，都作出了建设性的贡献。

Note that the direct conversion of nuclear energy to electricity is not how a nuclear power plant produces electricity; instead it uses the heat of a nuclear reaction to run a heat engine, and transforms the heat engine's resulting mechanical energy into electricity via magnetic induction.

请注意，核电站并不是通过直接将核能转换为电能来发电的，而是使用了热核反应驱动热力发动机，并通过磁感应将热机输出的机械能转化成电能。

Against the backdrop of growing tensions in the Middle East and nuclear "saber rattling" elsewhere in Asia, the authors point out that een the smallest nuclear powers today and in the near future may hae as many as 50 or more Hiroshima-size (15 kiloton) weapons in their arsenals; all told, about 40 countries possess enough plutonium and/or uranium to construct substantial nuclear arsenals.

在中东紧张局势加剧和亚洲核威慑的背景下，作者指出，当今或近期核力量最小的国家，在他们的兵工厂里也有相当于50甚至更多倍广岛原子弹（15千吨TNT当量）威力的核武器；总共大约有40个国家拥有足够的钚和/或铀制造大量的核武器。

Produce the basic conditions for thermonuclear reaction, first nuclear fuel must be heated to a temperature high enough (several tens of millions of degrees), this time the nuclear fuel has been ionized into a mixture of electrons and ions, namely plasma; Second, we must binding them together so that they have conducted nuclear reaction time.

产生热核反应的基本条件，一是核燃料必须加热到足够高的温度，此时核燃料已被电离成电子和离子的混合体，即等离子体；二是要将它们约束起来使它们有进行核反应的时间。

After the identification of SARs in Attacus ricini rRNA gene, its rRNA gene and NTS were also found to have the ability binding with the nuclear scaffold of Saccharomyces cerevisiae. The 1kb NTS fragment which can bind clearly with nuclear scaffold of Attacus ricini was the chief fragment binding with yeast nuclear scaffold. This indicated the homology between this two kinds of SARs and provided an evidence for the evolutionary conservation of SARs.

在鉴定蓖麻蚕rRNA基因中具有骨架结合区域之后，利用体外结合的方法发现，蓖麻蚕rRNA基因及其非转录间隔区片段也具有与酵母核骨架结合的能力，尤其是能与蓖麻蚕核骨架结合的非转录间隔区1kb片段，也能明显地结合于酵母核骨架，这一结果表明二者的SAR顺序具有一定的同源性，为骨架结合区域具有进化保守性提供了又一证据。

Methods Nuclear β-catenin expression was detected by immunohistochemistry in 77 lesions with desmoid-type fibromatosis and 171 other spindle cell lesions, including superficial fibrmoatosis (n=18), nodular fasciitis (n=36), keloid (n=16), scar (n=10), granulation tissue (n=9), synovial sarcoma (n=38), neufibroma (n=13), solitary fibrous tumor (n=12), gastrointestinal stromal tumor (n=10), low-grade myxofibrosarcoma (n=3), low-grade fibromyxoid sarcoma (n=3), and smooth muscle tumor (n=10). In addition, the immunohistochemical expressions of ER-α, ER-β and Ki-67 were examined in all of the lesions with desmoid-type fibromatosis. The nuclear immunohistochemical staining for nuclear βcatenin and ER-β was graded as high level (≥25% of cells), low level (5%-25%) or none.

采用免疫组织化学染色法检测77例韧带样型纤维瘤病和171例其它良、恶性梭形细胞病变（包括结节性筋膜炎36例、浅部纤维瘤病11例、瘢痕疙瘩16例、增生性瘢痕10例、肉芽组织9例、滑膜肉瘤38例、神经纤维瘤13例、孤立性纤维性肿瘤12例、胃肠间质肿瘤10例、低度恶性黏液纤维肉瘤3例、低度恶性纤维黏液样肉瘤3例及平滑肌肿瘤10例）组织中β-catenin核阳性的表达，同时检测韧带样型纤维瘤病中ER-α、ER-β和Ki-67的表达。

The Indica-Japonica differentiation is main trend in nuclear DNA,mtDNAand cpDNA in cultivated rice.The types of nuclear DNA,mtDNA and cpDNA insome accessionsare homeotype(nuclear DNA,mtDNA and cpDNA areall Indica type or Japonica type).

中国普野因地理分布不同，其遗传分化表现出多态性，江西东乡和湖南茶陵以及部分云南元江普野既不与籼稻聚在一起，又不与粳稻聚在一起，而独聚一类，其形态上亦比较原始，属于原始祖先型。

3Rhe distribution and change of proliferating cell nuclear antigen in seminiferous tubule: The positive staining of proliferating cell nuclear antigen was found in slices of all groups, the immunological positive products were located at karyon, usually in brown yellow granules, only a small part of them in diffuse state; the immunological positive cells were mainly the spermospores, besides a small quantity were spermiocyte, supporting the cell and myoid cell nuclear to be stained.

3增殖细胞核抗原在生精小管中的分布及变化：各组切片均可见增殖细胞核抗原阳性染色，免疫阳性产物位于细胞核，通常呈棕黄色颗粒，小部分呈弥散状；免疫阳性细胞主要是精原细胞，另外还有少量初级精母细胞、支持细胞和肌样细胞核着色。

The outer neuroblastic layer before it divided to inner and outer nuclear layer and outer complexiform layer and gonglion cell layer showed a temporal PCNA positive which was related to proliferation. The three cell layers had another PCNA positive when finished time changed from outer to inner after their morphologic development basically completed( outer nuclear layer:11～15 days,inner nuclear layer: 8～16 days, gonglion cell layer:16～21 days).

PCNA显示在外成神经细胞层分化为内、外核层和外丛状层之前，和节细胞各有一次和增殖相关的阳性表达。3个细胞层在形态学的分化基本完成后，又出现了一次结束时间是由外向内变化的阳性过程（外核层：第11天至15天：内核层：第8天至16天，神经节细胞层： 16天到21天，这一次阳性表达过程可见到细胞形态向成年形态的转化。
