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。

The increasing of cultivation density leaded to the decline of ear leaf physiological function and self-guard enzyme activity and eventually shortening leaf functional stage,decreasing its photosynthesis.

随着种植密度的增大，果穗叶光能转化和自身保护酶系活性下降，光合生产能力减弱，造成果穗叶生理功能早衰，缩短了叶片功能期。

N-use efficiency at mature stage were significant- negatively correlated with N-content of ear, leaf and sheath, N-accumulation and N- distribution ratio of leaf and sheath at late grain-filling stage and were significant-positively correlated with N- distribution ratio of ear at late grain-filling stage.

籽粒灌浆不同时期的氮素利用效率品种间呈显著差异，其中成熟期氮素利用效率与成熟期穗和鞘叶氮素含量、鞘叶的氮素积累量和鞘叶氮素分配比例呈显著的负相关，与灌浆中后的穗氮素积累分配比例呈显著的正相关。

Leaves variable, those on previous year's branches usually alternate, those on short branches approximate and often fascicled; petiole 1–2(–3) cm, glabrous, with 2 to 4 nectaries at apex or at base of leaf blade; leaf blade lanceolate to elliptic-lanceolate, 3–6(–9)× 1–2.5 cm, slightly pilose when young, glabrescent, base broadly cuneate to rounded, margin shallowly densely serrate, apex acute to shortly acuminate.

易变的叶，那些在通常互生的第二年分枝上，那些在短枝紧靠和通常簇生上；叶柄1-2(-3)厘米，无毛，具2在4蜜腺在先端或叶片的在基部；叶片披针形的到椭圆形披针形， 3-6(-9)* 1-2.5 浅的幼时的厘米，稍具柔毛，后脱落，基部宽楔形到圆形，边缘浓密有锯齿，先端锐尖到短渐尖。

Growth of plants was suppressed by 150mmol . L~-1NaCl stress, at the meantime, relative electric conductivity, leaf proline content and chlorophyll a/b increased, chlorophyll content, photosynthesic rate and transpiration rate decreased. Relative electric conductivity in root was more than that of leaf. The content of abscisin acid increased, while the content of gibberellin, Indoleacetic acid and zeatin decreased under salinity stress.

NaCl胁迫抑制草莓生长，引起草莓膜透性增加，脯氨酸含量和叶绿素a/b增大，叶绿素含量、净光合速率、蒸腾速率减小，ABA含量增加，ZT、IAA和GA含量减少，各处理根系膜透性大于叶片，且内源激素含量变化幅度比叶片小。

It was shown that the shapes of upper leaf epidermal cells varies from irregularly sinuolate, nearly elliptic to irregularly polygonal. The lower leaf epidermal cells are usually irregularly sinuous or sinuate. The patterns of anticlinal walls are sinuate irregularly, and the ambits are inconspicuous between the cells.

粗叶木属植物上表皮细胞形状一般呈不规则波状、近椭圆形或者不规则多边形，下表皮细胞一般呈不规则皱波状或者多裂深波状，细胞壁曲折无章，细胞间界限不明显，上、下表皮细胞壁均有加厚现象。

Leaf sheath auricles present, secondary veins of leaf blades 5–9-paired

叶鞘的叶耳宿存，叶片的次脉5-9配对 7

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。
