Under soil water stress conditions, the photosynthesis rate, water useefficiency and light compensation point of Atriplex canescens obviouslyreduced, and its dark respiration rate weakened. In the treatments in July, theaccumulative and average value of daily Pn from high to low is: light soil water stress>no soil water stress>medium soil water stress>heavy soil water stress, the valueare 7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1) and 1.761μmolm~(-2)s~(-1), respectively. In the treatments in August, the accumulative and average value ofdaily Pn from high to low is: light soil water stress>medium soil water stress>heavy soil water stress>no soil water stress, the value are 7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1) and 1.705μmolm~(-2)s~(-1), respectively.
在土壤水分胁迫下四翅滨藜的净光合速率、水分利用效率、和光补偿点显著降低,暗呼吸速率减弱。7月份各处理Pn全天的累计值和平均值的大小顺序为:轻度土壤水分胁迫>无土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫,它们的值分别为:7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1)和1.761μmolm~(-2)s~(-1)。8月份各处理的Pn全天累计值和平均值的大小顺序为:轻度土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫>无土壤水分胁迫,它们的值分别为:7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1)和1.705μmolm~(-2)s~(-1)。9月份四翅滨藜的Pn变化趋势于8月份的变化曲线基本相似,唯一不同的变化就是各个处理的Pn比8月份的要高,这可能于9月份气温降低,湿度增大有关。

The micelle shape transformation of tert-octylpheny phenol polyethylene glycol ether (TX-100), sodium dodecyl benzene sulfonate and tetradecyl trimethyl ammonium bromide in heavy water solutions was studied by 1H nuclear magnetic resonance spectroscopy, including an NMR self-diffusion experiment. These experiments showed that the surfactants formed several shapes of micelles (spherical, ellipsoidal, and rodlike) at the respective concentrations which were far above their critical micelle concentration.
