解除干旱胁迫后，黑云杉的气孔敏感性、光合能力及水分利用效率的恢复都要比北美短叶松更快。轻度的干旱胁迫锻炼可以帮助北美短叶松在更严重的干旱胁迫下保持固有而强劲的耐旱能力。

Kalanchoe; sunken or protected stomata e.g. marram grass; folding, rolling or repositioning of leaves to reduce sunlight absorption, e.g. marram grass; a dense covering of white reflective spines, e.g. cacti; and the development of a dense hairy leaf covering, e.g. Espeletia.

通过减少水分流失而生存的旱生植物的生存策略包括：落叶，如：墨西哥刺木；分泌蜡质覆盖叶片使气孔器被封闭或堵塞，如：滨草；折叠、卷曲或重新排列叶序而减少对日光的吸收，如：滨草；喜砂草盖白色的可以反射太阳光的刺，如：仙人掌；还可以发展出密毛状叶片铺满全身各处，如： Espeletia 。

The results indicated that the actual inhibition ratio and the theoretical inhibition ratio of net photosynthate and stomatal conductance of glyphosate-ammonium and fluroxypr-mepthyl (4:1) mixture against Altemanthera philoxeroider were from 80% to 100%, and those of intercellular CO2 concentration, content of chlorophyll and malondialdehyde were above more than 110%, and strong synergism.

结果表明，该配比混剂处理对空心莲子草净光合速率和气孔导度的实际抑制率与理论抑制率的百分比在80%~100%之间，表现出相加作用；而对胞间CO2浓度、叶绿素含量及丙二醛含量的实际抑制率与理论抑制率的百分比均在110%以上，表现出较强的增效作用。

The mode field of photonic crystal fiber structured with hexagon symmetry hole cladding was analyzed by coupled-mode, and the effective indexes of base mode of different wave length were got. The characteristics of this photonic crystal fiber grating were computed and simulated by coupled-mode method and transmission matrix method. Moreover, the differences were compared between conventional fiber grating and photonic crystal fiber grating on their reflection spectrum and delay.

利用多极法对包层空气孔为正六边形对称结构光子晶体光纤的模式场进行了分析，计算出不同波长下基模的有效折射率，结合使用模式耦合理论和传输矩阵法对基于光子晶体光纤的布拉格光栅特性进行了计算和仿真，对比了常规单模光纤所成光栅与相同光栅周期的光子晶体光纤布拉格光栅反射谱及时延特性之间的差异。

Asaresult, water use efficiency of spring wheat was raised and its production was increased.

虽然气孔导度的增大增加了作物的耗水，但由于施磷对失水的促进小于对产量的促进作用，因而明显提高了春小麦的水分利用效率。

The characteristics of clonal growth and resources sharing were important to keep stability of community. The transpiration and the stomatal conductance of stolon with and without adventitious roots were same. But the water potential of stolon without adventitious roots was higher than that with adventitious roots.

臭柏克隆生长和资源共享特性在维持群落稳定中起着重要作用，来源于同一上级枝的匍匐茎，有不定根的和无不定根的日平均蒸腾速率和气孔导度没有差异，但无不定根匍匐茎的叶水势比有不定根的高。

Studies of using Ca〓 channel blockers and the Ca〓 chelator EGTA further demonstrated that Ca〓 also involved in signal transduction of NO-induced stomatal closure.

使用钙的螯合剂、质膜Ca〓通道的阻断剂NIF和LaCl〓及细胞内Ca〓通道的抑制剂进一步证明Ca〓也参与NO诱导气孔关闭的信号转导。

Based on the analysis of formation mechanism of shrinkage, dispersed shrinkage, gas cavity and blow hole shrinkage in the brake hub castings of Santana car, some methods are put forward to solve these problems.
