We think the way to resolve this matter, to achieve the objective that China believes in, and we believe in, which is to have a nuclear-free Korean peninsula is for North Korea to ae to the complete, verifiable and irreversible dismantlement of their nuclear weapons capabilities.

我们觉得解决这个问题的方法是建立一个无核的朝鲜半岛，这是中国的目标，也是美国的目标。它要求北韩以彻底的、可核查的、不可逆转的方式拆除其所有核能力。

Seedless grape is one of important direction of consumption and breeding.

无核葡萄是当今世界葡萄消费和育种的重要方向之一，但生产上主要栽培的欧洲葡萄无核品种抗病性差，中国野生葡萄是抗葡萄真菌病害的重要基因资源。

Effects of different fruit-retaining reagents upon fruiting on Yunan seedless wampee;2. To probe into the seedless reason of fruit of the Linyuan 1 seedless wampee ,the Linyuan 1 seedless wampee is observed at its flower organs, pollen quantity and degree of satiation, and germination, and compared with the seed wampee.

为了探讨林院 1号无核黄皮果实无籽的原因，于 1992年～ 2 0 0 0年在广西大学林学院观察林院 1号无核黄皮的花器、花粉数量及饱满程度、花粉萌发情况，并和有核黄皮比较；采用随机区组试验设计，对林院 1号进行自然授粉、去雄不授粉套袋、去雄后用有核黄皮花粉授粉并套袋的授粉试验；观察林院 1号的授粉受精过程。

Genetic distance data showed that the heriditary conservation among 11of 14 studied cultivars (except Longshan akaryotic wampee, Longchuan akaryotic wampee and white sugar karyotic wampee) was very high (D≤0.1), which suggested that the genetic relationship between theses cultivars was very close.

结果表明，除龙川无核黄皮、龙山无核黄皮和冰糖黄皮外，其它11个品种间的遗传距离较近（D≤0.1），说明大多数黄皮品种遗传差异较小，亲缘关系较近。

A eupyrene sperm and an apyrene sperm combined together forming a normal mature sperm, and the function of apyrene sperm was helping eupyrene sperm to swim.

The degree of seedlessness varies greatly among seedless grape varieties.

来自纽约的计划有希望的选择是可用于测试目的。对无核程度参差不齐无核葡萄品种。

At the same time, a chimera gene pTA29-Barnase, which can induce male sterility in transformants, was transferred into three seedy cultivars (Valencia, Ponkan and Anliucheng) to obtain male sterility citrus plantlet in the future. It is a new strategy for seedlessness breeding in citrus.

同时，以柑橘的无核育种为目标，在建立的转化体系的基础上，将人工雄性不育基因pTA29-barnase转入三个多籽品种（伏令夏橙、〓柑、暗柳橙）中，以期创造新的柑橘雄性不育类型，并为今后柑橘的无核育种提供新的思路和材料。

The mechanism of triploid seedlessness, evaluation approaches of triploid grapes and embryo rescue technique are also discussed. Seven newly bred triploid seedless cultivars in the world are briefly described such as Yileyi, King Dela, Honey Seedless, Kai Mi...

简要介绍了国内外育成的7个三倍体无核葡萄新品种尾玲、戴拉王、蜜无核、美嶺、夏黑、无核早红和马格拉契的特征特性，并讨论了三倍体无核葡萄育种存在问题和未来的研究重点如杂交亲本的选择、三倍体杂合胚的发育特点和无核性状的遗传规律等。

In this research it was established that a method of isolation of total RNA from Ziziphus jujuba Mill. cv. wuhexiaozao and Ziziphus jujuba Mill. cv. jinsixiaozao fruit which were from different grown time. Also the Reverse Transcription System for Chinese jujube fruit was established in the research. The purpose of this research was to lay a solid foundation for cDNA-AFLP analysis, to illustrate the mechanism of stoneless of Chinese jujube, to clone the gene to stoneless, to cultivate new Chinese jujube cultivars by gene modified breeding.

以无核小枣和金丝小枣不同发育时期的果实为试材，建立适宜枣果实总RNA提取的方法及其反转录的技术体系，为进一步进行枣果实cDNA-AFLP分析及有关的分子生物学操作，阐明枣无核突变体的分子机理，并克隆枣果实无核突变体相关基因，通过基因工程培育优良的无核枣品种奠定基础。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
