The leaf WUE of millet was increased when root cutting in seedling stage,and only the treatment of I2D of maize increased the leaf WUE; The biomass WUE of millet and maize were increased excepting the root cutting treatments of "TM" and "sl"; At the 80% field capacity, when the root was cutted more seriously and more later,the seed yield WUE of millet were dropped; While at the 50% field capacity, the seed yield WUE of millet was increased when the root cutting is moderate in prophase,and have no reduction of output or increase the production at the same time ,while the benefit of saving water didnt evidently at the later stage root cutting.

苗期伤根处理能够提高谷子叶片WUE，而玉米伤根后仅I2D处理的单叶WUE高于对照；除TM和sl处理外，伤根处理提高了谷子和玉米生物量WUE；在土壤含水量为80%田间持水量时，随着伤根程度的加剧和伤根时间的后移，谷子子粒产量WUE下降，伤根不利于谷子WUE的提高；而在50%田间持水量时，前期伤根量适度的处理在不减产甚至增产的情况下还有助于作物子粒产量WUE的提高，而后期伤根的节水效果并不明显。

Thedeep cultivation-root cutting in before winter stage would delay the de-crease of root vigor、the activity of superoxide dismataseand catalse、and the soluble protein content in flag leaf and root system after an-thesis,while delay the increase of malondiadehydecontent in flag leafand root system in different soil depth,the results would delay the senes-cence of flag leaf and root system.

冬前深耘断根可延迟花后不同土层深度根系活力、根系与旗叶SOD与CAT活性、根系与旗叶可溶性蛋白质含量下降及根系与旗叶MDA含量的升高，从而延迟根系与旗叶衰老。

According to the size of door leaf, make sure of the amount of rolled hinge each door needs, then draw lines on the door leaf.

Compared with the control, 10–50 mg/L ALA had no significant effect on the leaf water use efficiency at flowering and milky stage, while increased the leaf water use efficiency significantly at dough stage.

在开花期和乳熟期，10～50 mg/L ALA处理的叶片水分利用效率与对照没有显著性差异，但在腊熟期，叶片水分利用效率较对照有显著性提高。

Some drought-resisting indices were observed in the condition of controlling water supply artificially on potted planting Ceratoides, the results as follows. Leaf water content was gradually decreased with the drought stressed days increasing. In the stressed period, the decrease of C.arborescens's leaf water content was more than that of C.lanata.

试验通过盆栽控水的方法进行各指标的测定，经过分析，结论如下：叶片含水量和相对含水量随着胁迫天数的增加而逐渐减少，胁迫期间，华北驼绒藜的降幅明显低于绵毛优若藜，前者在胁迫期间变化平缓，后者下降幅度较大，不同处理天数间存在明显差异。

After reading "Leaf Ear" and "Leaf Ear's End", the two books in today's afternoon, tears were in my eyes although the story was so simply and the end was within expectation.

看完《左耳》和《左耳终结》，我的眼眶已经湿漉漉。其实故事是很简单的，结局甚至有些老套，但还是在一个下午看完了两本。

The results showed that under increasing field temperature in the period from male tetrad to maturing stage, the grain yield of ND108 and YD13 decreased by 46.6% and 45.1%, leaf area index decreased by 15.4% and 11.5%, and net photosynthetic rate of ear leaf decreased by 22.85% and 18.14%, respectively, compared with the control.

结果表明：大喇叭口期到成熟期增温显著降低了夏玉米籽粒产量，ND108和YD13的籽粒产量分别较对照降低了46.6%和45.1%；叶面积指数平均值分别降低了15.4%和11.5%；穗位叶叶片光合速率平均值分别降低了22.85%和18.14%；两个玉米品种叶片的叶绿素a和叶绿素b含量显著降低，但对叶绿素a的影响更显著。

The main causes resulted in the yield and quality difference among treatments were that it was beneficial to decomposing and releasing nutrients in compost when mixed EM and it was raised significantly for the rapid availability of Nitrogen, Phosphorus and Potassium in soil applied EM biological-organic fertilizer, which increased the Nitrogen, Phosphorus and Potassium nutrient content in stem, leaf blade and ear and improved the organism function, and then the chlorophyll content and rate of photosynthesis of crop functional leaf blade were raised, the strengthened photosynthesis increased the plant dry matter content, thereby laid a foundation for seed-filling.

分析产量提高和品质改善的原因，得到以下结论：EM的加入促进了有机肥养分的分解和释放，EM生物有机肥土壤的有效氮、磷、钾含量显著提高，充足的肥料供给使植株的N、P、K含量增加，机体的功能得到改善，作物功能叶片的叶绿素含量和光合速率提高。光合作用的增强促使植株干物质积累量增加，从而为灌浆和籽粒饱满打下坚实的基础。

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。
