Photosynthetic and respiration rate of Haematococcus pluvialis cultured in modified MCM medium under artificial conditions was calculated by measuring the rate of oxygen production and consumption in 1994 in Qingdao.

于 1 994年在青岛以单细胞雨生红球藻为实验材料，利用MCM改良配方制作培养液，采用测溶解氧的方法，进行了光合和呼吸速率测定。结果表明，雨生红球藻光合速率、呼吸速率不仅与温度、光照强度有密切关系，同时还与其生活史中不同发育阶段有关。

Based on the data of dynamic shear rheometric tests, a constitutive equation was also proposed, which could characterize the dependence of the melt viscosity of PE and its blends on both shear rate and temperature.

此外，在大量mPE和mPE/LDPE共混合金动态剪切流变试验数据的基础上，拟合并推导出能够同时反映PE和mPE/LDPE共混合金熔体粘度对剪切速率和温度依赖性的本构方程，并且通过分析发现，方程中的α值对PE和mPE/LDPE共混合金的熔体粘度的剪切速率依赖性影响较大，α值越大，其熔体粘度对剪切速率越敏感。

Diurnal changes of photosynthetic rate and transpiration rate of Leymus chinensis were investigated by Li-6400 in saline sodic grassland,and relationship among the factors affected Pn and Tr was analysised.

The results showed that, under the condition of soil water stress during the flowering stage of potato, the daily changes of net phoTo,synthetic rate, transpiration rate and stomatic conductance were parabola type.

结果表明，在马铃薯生育关键期土壤水分亏缺情况下，4种处理叶片净光合速率、蒸腾速率和气孔导度的日变化曲线均为开口向上的抛物线，而净光合速率日变化是气孔调节作用的结果。

When the relative soil water content were 55%-40%, the main reasons of the photosynthetic rate declined were stomatic limitation. When the relative soil water content were 20%, the main reasons of the photosynthetic rate declined were nonstomatic limitation.

干旱胁迫下，光合速率的下降是气孔因素与非气孔因素双重作用的结果：轻度干旱胁迫下（土壤相对含水量55%~40%）气孔限制是光合速率下降的主要原因，而严重干旱胁迫下（土壤相对含水量20%）非气孔限制是光合速率下降的主要原因。

According to transpiration rate, extracells CO2 concentration, stomatic conductance of four alfalfa varieties under water-stress, it was concluded that reduction of photosynthetic rate was primarily resulted from stomatal factors under light and medium water stress and nonstomatal factors under severe water-stress in the experiment during branching.

通过分析水分胁迫紫花苜蓿分枝期叶片气孔导度、蒸腾速率和胞间CO2浓度的变化，认为试验中轻度和中度水分胁迫下光合速率下降的主要因素是气孔因素，重度水分胁迫下光合速率下降的主要因素是非气孔因素。

The results showed that the growth of Jinguang plum seedlings were remarkably restrained by salt stress. With the increasing of salt concentration, the plant height, leaf area, leaf fresh weight, leaf dry weight, stem dry weight and root dry weight were remarkably decreased, and the chlorophyll content, photosynthesis rate, transpiration rate and stomatic conductance in leaves were declined too, but the intercellular CO2 concentration was inclined.

结果表明盐胁迫抑制了金光杏梅幼苗的生长，随着盐浓度的升高，金光杏梅的株高、叶面积、叶鲜重、叶干重、茎干重、根干重均显著降低；叶片叶绿素含量、净光合速率、蒸腾速率、气孔导度亦显著降低，且盐浓度越高，下降幅度越大；细胞间隙CO2浓度随着盐浓度增加而增大，表明盐胁迫下非气孔因素是导致金光杏梅叶片光合速率下降的主要原因。
