其中，种子千粒重变异最大；旗叶长度、花序形状次之；穗叶距、花药宽度、旗叶宽度等性状变异中等；而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性，花序直立、紧缩的鸭茅，叶片窄长，茎秆粗壮，旗叶较长，雄性生殖器官发育良好，结种性能强；而花序下垂、开展的鸭茅则与之相反。3聚类分析表明，不同野生鸭茅种源可划分为3类，其中花序下垂种源聚于一类；而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析，花序直立的鸭茅更具开发利用潜力。

Fifteen japonica and 15 indica rice cultivars were grown in the field for two crop seasons both in Taipei and Taichung. Samples were taken at 4 different growth stages (booting, heading, milky and dough stage) during each season to obtain data of leaf atea index, leaf area duration, leaf N concentration, the amount of dry matter accumulated , crop growth rate, and net assimilation rate.

Removing 3/4 ear treatment accelerated flag leaf senescence, and delayed the top 2nd leaf and top 3rd leaf senescence.

剪3/4穗处理明显加速了旗叶的衰老，而使倒二叶和倒三叶的衰老得以延续。

The dynamic changes of Ch0 in leaves showed different patterns, with little changes at different assaying points in the lower leaf and a single peak curve in the ear leaf and upper leaf.

Hill反应活力、Ca^2＋-ATPase活性和Mg^2＋-ATPase活性的变化规律不同，随生长进程表现不断下降、单峰曲线和双峰曲线等不同形式。

With the growth progress, the P and pro in all tested leaves gradually decreased. The dynamic changes of Chl in leaves showed different patterns, with little changes at different assaying points in the lower leaf and a single peak curve in the ear leaf and upper leaf.

植株不同叶位P和Pro随生长进程均不断下降；不同叶位Chl的变化动态表现为下位叶在各测定时期之间差异较小、穗位叶和上位叶为单峰曲线。

Leaf angle above ear of super high yield maize was less than 20°, leaf angle of ear was between 25°and 35°, and leaf angle below ear was about 35°.

根冠关系分析表明，根系分布越集中，在深层土壤中分布比例越大，株型越紧凑。

The physiologic changes of leaf vegetables after picked and the basic principles of the technology for keeping fresh were discussed. The effect of MAP on leaf vegetables stored in different component gas at normal temperature was studied with cabbages, caraways, leeks, to select the best packaging atmosphere for keeping leaf vegetables fresh.

论述了叶菜类蔬菜采后的生理变化和气调包装保鲜的基本原理，并以小白莱、香菜和韭菜为例，对常温叶菜在不同气体成分下的气调保鲜进行了实验研究，提出了适合叶菜气调包装保鲜的最佳气氛配比。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species （ r = 0.93, p 〈 0.01）. Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher Pn, Tr and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
