Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

According to SIT, we could make the following hypotheses on the social behavior of a state: the state will favor in-group countries, take win-win strategy with the group it identifies, and be prone to cooperation in bilateral relations; the state will take non-zero-sum strategy with out-group countries and choose partially participation and cooperation; for the out-group countries with high hostility, the state will take zero-sum strategy, and choose non-cooperation or conflict.

根据社会身份理论，我们对国家的社会行为提出了如下假设：国家会更偏向于内团体国家，对于自己所认同的国家集团会从双赢的思维出发，选择积极合作的战略；对于外团体国家，一般会从非零和的思维出发，在双边事务中选择部分的参与和合作；而对于敌对性较高的外团体国家，一般会从零和的思维出发，在战略上选择不合作或冲突。

The advances and existing problems concerning in genetics especially on the sex-inheritance and tolerance to papaya ring spot virus, the genetic improvement (cross breeding, mutation breeding, introduction breeding, culture in vitro, molecular marker assistant selection and bioengineering) on papaya are reviewed; especially on the sex-inheritance, distant hybridization and embryo culture, and breeding for disease resistance to PRSV with gene engineering are discussed in detail.

就番木瓜的株性和抗病性等性状遗传、杂交育种、人工诱变育种、离体培养、分子标记及基因工程育种等现代生物新技术育种方面的研究进展及相关问题进行了评述，重点综述了番木瓜株性遗传、远缘杂交与胚胎学、基因工程在抗环斑型花叶病毒病品种培育及分子标记辅助选择育种应用的研究进展，并分析了今后番木瓜育种的发展趋势。

They have normative validity in the fields of social life wherein positive norms cannot substitute. If positive norms intrude into their fields and result in failing adjustment, factive folk norms would passively come up in the judicial course and demonstrate their unique significance in terms of legal method. In such case, the only proper judicial decision of a judge is to abandon the "imperialism of positive norms" and revert to the original function of factive folk norms.

它在实在法不可僭越的社会生活领域拥有规范力量，一旦实在法闯入这一领域而导致&调整不能&的后果，则事实性民间规范就可能在司法过程中被动出场并展示独特的法律方法意义，此时扬弃&实在法帝国主义&并恢复事实性民间规范的本有功用，就是唯具妥当性的裁判选择。

Despite the poor response rates in the chemotherapy-alone group, Dr. Burstein believes that metronomic chemotherapy combined with bevacizumab should be investigated further, given the tolerability of the agents and the preclinical rationale for efficacy. When asked why cyclophosphamide and methotrexate were selected for metronomic chemotherapy, he observed that many patients in this setting are already somewhat chemotherapy-resistant.

尽管只接受化学疗法的病患反应率很低，Burstein医师相信节律性化学疗法加上bevacizumab应该进一步研究，因为该药物的耐受性良好，而且临床前实验认为是有效的；当被问到为什么选择cyclophosphamide与methotrexate作为节律性化学疗法的药物，他观察发现，许多病患在这个时候已经对许多化学疗法产生抗药性。

With proper atomic coherence, the performance has the following advantages compared with that of the velocity selection of the ultracold two-level atoms by the micromaser: high resonant transmitted efficiency, low unresonant transmitted efficiency, and large velocity selection scale. The second part includes the fifth chapter.

原子透射几率只受到一种量子干涉效应的影响，其来源为V型的两个跃迁通道，因此Micromaser对入射超冷V型三能级原子束速度的选择性能深深地受到原子相干性的影响，我们发现选取适当的原子相干参数以及其它参数，速度选择性能可以达到很理想的状态：共振原子透射效率高、透射原子束的速度纯度好、速度选择范围大。

If peasants are in a heavy pressure from capital restriction, they may have to sell at the "three sale fastigiums" and lose their opportunities of maximizing their sale profits.

回归结果在整体上验证了本文的整体分析及具体假说，农户的农作物品种越特殊、农户家庭经济中农业比重越高、户主信息可得性越强，农户越倾向于选择&新型销售方式&；农户面临的资金约束是农户选择在&三大销售高峰期&销售的最重要原因，当农户的资金压力形成硬约束时，农户没有选择实现利润最大化的销售时机的自由。

The temperature behavior in mats was measured using CopperConstantan Thermocouples, and the core temperature cure during both pressings was simulated by means of a computer under various conditions.Reflected-fluorescence microscopy and image analysis techniques were used to measure the flow and penetration of PF adhesive into the Polar flake under various steam-injection-vacuum-pressing conditions. The paper also studied the effects of adhesive and penetration on flakeboards'mechanical properties.

研究结果表明：采用聚合度较大的水溶性A阶酚醛树脂胶，可以比较有效地克服目前水溶性酚醛树脂胶喷蒸热压大片刨花板中的树脂胶过度稀释、渗透及胶线缺胶的问题；适当选择饱和蒸汽压力、喷蒸时机、喷蒸时间、蒸汽保持时间和抽真空处理程度，是解决目前水溶性A阶酚醛树脂胶在喷蒸热压中所存在的问题的另一个重要途径。
