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。

After NMDA stimulation, he concentrations of Ca~2+ and NO in both nuclear and plasma rise observably, especially in the netlike structures; the change of Ca~2+ concentration in nuclear is larger than that in plasma,however the changes of NO concentration in nuclear and plasma are similar. We also observed comparative increases of the concentration of Ca2+ and NO in neurodendrite after NMDA stimulation.

NMDA刺激后神经元细胞核和细胞质内Ca~(2+)和NO都明显升高，尤其在细胞核和细胞质内的网状结构处；细胞核内Ca~(2+)升高幅度大于细胞质，而细胞核内NO的升高幅度却与细胞质相近；另外，树突内的Ca~(2+)和NO升高也较明显。

George Quester,"The Shaw and the Bomb"(unpublished paper, 1975), and a private interview conducted in February 1975; in Anne Hessing Cahn,"Determinants of the Nuclear Option: The Case of Iran," Nuclear Proliferation in the Near-Nuclear Countries (Cambridge: Ballinger Publishing Co., 1975), Onkar Marwah and Ann Shulz, eds., p.

Also, analysts note, while North Korea has blustered about having nuclear capacity, last Thursday was the first time it publicly used the phrase nuclear weapons to refer to its nuclear program.

而且，分析家指出，上星期朝鲜叫嚣拥有核能力时，它第一次公开使用核武器一词来指称它的核计划。

These two sets of neutron optical potential parameters have been ingathered in the Nuclear Parameter Data LIBRARY of China by Chinese Nuclear Data Center.Based on these neutron optical potential parameters, program DWUCK4 has been applied to calculate direct inelastic cross sections which are used in SUNF program as input data and then the SUNF program has been used for calculating all nuclear reaction data of neutron induced on 135Ba, 136Ba, 137Ba, 138Ba and 130Te in energy range from 0.01 to 20MeV, respectively.

在这两组中子光学势参数的基础上，应用程序DWUCK4计算了直接非弹截面，作为输入数据用于SUNF程序，用SUNF程序计算了中子入射~(135)Ba、~(136)Ba、~(137)Ba、~(138)Ba和~(130)Te五个核的反应全套数据。

There is widespread disagreement over the progress of Iran's nuclear program toward developing such a weapon, but miniaturizing nuclear weapons for use on long-range missiles is one of the most difficult technological hurdles for an aspiring nuclear nation.

有关伊朗核计划在这种核武器方面的进展存在着各种分歧，但对于一个充满核野心的国家，将核武器缩小到能够用远程导弹发射是最困难的技术障碍之一。

The North Korea Nuclear Crisis made the Peninsula's situation tenser, gave US excuse to intervene the Peninsula's affairs, and gave Japan the chance to enhance its military power and to develop nuclear weapons. It could induce a "domino effect" of a nuclear proliferation.

但朝鲜核危机使半岛局势更加紧张，为美国对东亚事务的介入提供了借口，为日本大力增强其军事力量甚至核武器提供了契机，并有可能出现核扩散的&多米诺骨牌&效应。

They especially want answers about studies that appear to show as yet undisclosed uranium-related work, high-explosive testing of triggers for nuclear bombs, a plan for an underground nuclear-test shaft and efforts to redesign the nose-cone of Iran's far-flying Shahab-3 rocket to accommodate a nuclear warhead.

IAEA也特别关注下面一些问题的答案：秘密进行的铀关联工程；击发核弹的高爆试验；地爆竖井计划；伊朗是否对&流星3&型远程地对地导弹头锥改进，使之具有配载核弹头的能力。

But GST= 0.156, Nm=1. 588. As a result, the foundation of Youyongchi Avicennia marina population was the result of the migration of hypocotyles and human factors.

这项工作可以为海岸防护林中新引进种类的判定以及为研究种群建立者效应方法的确定提供科学依据。

The two-dimensional CDRC-ADI-FDTD update equations for collision unmagnetized plasma are induced. The unconditional stability of the CDRC-ADI-FDTD formulation for collision unmagnetized plasma is obtained by the examples.

推导了碰撞非磁化等离子体中的二维CDRC-ADI-FDTD迭代公式，并用算例验证了碰撞非磁化等离子体CDRC-ADI-FDTD算法也是无条件稳定的。
