孟庆伟等（1996）认为光呼吸可减轻光抑制，尤其在发生光合午休时更明显，而对光合作用却有反作用，Zelitch (1992)的研究表明光呼吸随温度的升高而升高，因此高蛋白小麦中午较强的光呼吸作用可能是其Fv/Fm下降较少，而净光合速率下降幅度较大的一个重要原因。

This Father of light together with the light-air and the light-earth, the former with five attributes parallel to his own, and the latter with the five limbs of Breath, Wind, Light, Water, and Fire constitute the Manichan pleroma.

这个父亲的光与光的空气和光的地球，前5个属性平行他自己，后者则与5四肢呼吸急促，风，光，水，火，构成了

Second, in this paper we recite and analyse how the painting masters of the different history stage used light and colors from "Prehistorical art" to "Rome art" imitating light and colors,"Middle ages art" creating "Sanctitude light","Revival of learning" representing nature light and colors and then light was used to create the drama light, Impressionistic using the light of science and impairing light instead emphasizing sensibility colors in modern times. Painting lives by the light and colors all along in the painting history.

从史前艺术、希腊罗马艺术的模仿光与色，到中世纪艺术创造神圣之光，再到文艺复兴的再现自然光线与色彩，然后到17世纪的主观处理光线形成&戏剧之光&、印象派的科学用光、现代绘画淡化光线并强调情感色彩，光线和色彩一直贯穿在历史的绘画长河里。

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。

The results showed that the light saturation point of potato leaf was about 1400 μmoll(m^2s) and its light compensation point was about 50 μmoll(m^2s), the stomatic conductance and the transpiration rate increased while the intercellular CO2 concentration reduced with the increasing of light intensity between the light compensation point and light saturation point.

试验结果表明：马铃薯叶片光合作用的光饱和点约为1400 μmol/(m^2s)，光补偿点约为50μmol/(m^2s)。在光饱和点和光补偿点之间，随著光合强度的增加，叶片的气孔导度和蒸腾速率升高，胞间CO2浓度降低；随著CO2浓度的增加，光合速率升高，其CO2的饱和点约为2000μmol/mol。

The two-photon absorption cross-sections of these styryl derivatives were determined by Z-scan technique, and the benzothiazolium derivatives exhibited the largest TPA cross-sections (10〓s·cm〓/photon) and the best power limiting ability at high operable incident intensity. The results show that the benzothiazolium derivatives are promising organic compounds as two-photon absorption optical limiting materials. 2. Several organic dyes active to 800nm femtosecond laser with D-π-A structure were designed and synthesized.

研究了它们的上转换荧光、上转换激射和光限幅行为，通过改变染料分子共轭体系的大小，首次实现了在576nm-635nm范围内的双光子上转换激光波长的调节，其中噻唑啉碘盐类二苯乙烯化合物的双光子上转换激射峰（576nm）是迄今在1064nm皮秒激光作用下能够得到的最短波长的激光；阴离子显著改变上转换激射效率，但对上转换荧光峰和激射峰的位置影响很小；增加溶液的浓度，上转换荧光光谱和激射光谱红移，并在一定的浓度范围内，能够有效的提高上转换激射效率；利用Z-扫描技术测定了染料分子的双光子吸收截面，发现苯并噻唑类染料分子的双光子吸收截面高达10〓s·cm〓／photon，而且在较大的入射光强范围内，这类染料分子具有较大的光限幅能力，是一类作为双光子吸收光限幅材料很有潜力的染料分子。

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。
