由小麦叶锈菌引起的小麦叶锈病是小麦生产上的主要病害之一，适宜范围广，发生区域大，严重发生时可造成5%—15%甚至更高的产量损失。

In order to discuss the signal transduction mechanism,wheat cultivar Lovrin10 and different leaf rust fungus races were used to form compatible and incompatible interaction groups to study the role of drugs affecting calcium metabolism and calcium channel on HR induced by wheat leaf rust fungus.

为进一步探讨小麦抵抗叶锈菌侵染的防卫反应的信号转导机制，利用小麦品种洛夫林10和不同叶锈菌生理小种组成亲和与不亲和组合，研究影响Ca2+代谢和钙通道的药物对小麦受叶锈菌侵染后诱发的HR的作用。

Correlation analysis showed that meteorological variables, such as containing water rate of sandland, photosynthetic available radiation, air temperature, saturated water vapour pressure difference, and physiological variables, such as leaf area index, leaf temperature, stomatal conductance, affected transpiration of S.

相关分析结果表明，环境因子，如沙地含水率、太阳有效辐射、大气温度和饱和水汽压差，以及植物因素，如叶面积指数、叶片温度和气孔导度等，均能显著影响沙柳的蒸腾作用。

Flip the leaf horizontally and scale down the leaf.

倒装叶片水平，并缩小叶片。

However, a number of vegetation indices are not linearly related to biochemical components, so these indices may not be appropriate for other vegetative areas. We selected two different scale parameters, leaf chlorophyll content and leaf area index, on the basis of the radiative transfer models PROSPECT and SAIL, respectively, for sensitivity study of a set of indices.

为了寻找合适的波段位置以改善植被指数与叶绿素浓度和叶面积指数的线性关系，去除饱和区域，进而提高这2个参数的实际估算精度，该文选取了叶绿素浓度和叶面积指数，以辐射传输模型PROSPECT和SAIL为基础，模拟了这2个参数变化对3类高光谱植被指数归一化植被指数(NDVI、优化的简单比值指数和优化的叶绿素吸收率指数的影响。

With unit integrating and scale conversion, the transpirations determined by lysimeter and L I21600 stoma mete r are analyzed wit h Variance Analysis Method. The results s how that the difference between species is significant (P.05), but t he difference between methods is not significant. It indicates t hat t he scale conversion between leaf level and plant population level based on canopy and leaf area index is successful.

通过单位换算统一和尺度转换，蒸渗池和LI1600气孔计测定结果进行方差分析，表明物种间差异达显著水平(P.05)，测定方法间(蒸渗池和LI1600气孔计)差异不显著；从而说明本研究以叶面积指数和植物冠层盖度为基础，进行叶片水平与种群水平间的尺度转换是可行的。

Leaf sheaths glabrous or pubescent; auricles acute erect swellings or absent; leaf blades conduplicate,(1.5–)5–10(–14)× 0.2–0.4 mm, 0.5–0.8 mm deep, veins 5–7(–9); adaxial to abaxial sclerenchyma strands absent, abaxial sclerenchyma in 3 narrow discrete strands; ligule 0.1–0.4 mm, margin ciliolate.

叶鞘无毛或被短柔毛；叶耳锐尖直立或无；叶片对折，( 1.5-)5-10(-14)* 0.2-0.4 毫米，0.5-0.8毫米深，脉5-7-9；缺席背轴sclerenchyma股，在3 狭窄的分离的股的背轴sclerenchyma正面；叶舌0.1-0.4毫米，边缘具短缘毛。

Basal and cauline leaves 2 or 3; leaf sheath auricles well developed; leaf blade terete, 2--27 cm, on cauline leaves tubular and distinctly septate.

基生和茎生叶2或3；叶鞘的叶耳发育良好；圆柱状的叶片，2-27厘米，茎生叶上管状和清楚具隔的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
