The measured data were fitted with the modified rectangular hyperbola models of the photosynthetic responses to flag leaf intercellular CO2 concentration A/C(subscript i and air CO2 concentration A/C(subscript a aimed to approach the reasonability of the fitted results obtained from the models.

结果表明：由A/C和A/C修正模型所给的光合能力和CO2补偿点几乎相同，但得到的光呼吸速率和初始羧化效率则完全不等；产生这种差异的原因是利用叶片气体交换测定的数据所计算的胞间CO2浓度并不是植物叶片本身的胞间CO2浓度；A/C修正模型比A/C修正模型更为合理是因为A/C所估算的光呼吸速率接近测量值。

Diurnal fluctuation of physiological rate of leaf was a not obvious two-hump curve and diurnal fluctuation of transpiration rate was a typical resupinate "U" and the Pn and Tr in a.m.

通过对黄土旱塬冬小麦叶片光合生理指标、水分利用效率及其对环境因子的响应进行分析，结果表明：净光合速率日变化呈不明显的双峰曲线，蒸腾速率日变化呈明显的倒"U"型曲线，两者上午都明显高于下午，且不同生育期峰值出现的时间不同。

In the case of higher plastic viscosity, it was calculated at lower shear rate on the assumption of the same relationship, around 50 to 100 1/s of shear rate, because of the mechanical limit of the rheometer used.

要计算更高的塑性粘度，鉴于所使用的流变仪的机械限制，只能以相同的1秒剪切速率约50至100之间的关系为假设，以较低的剪切速率来计算。

The maximum growth rate is 0 22 cm d , and appears in ramification period Its community structure is reasonable rhomboid structure The leaf stem ratio will increase with increasing the height of plant .

出现在分枝期末期；绝对生长速率和相对生长速率在整个生育期内呈单峰曲线，最大值出现在分枝前期；其群落结构为菱形结构，是一个合理的株型结构；叶茎比随离地高度的增加而增加，符合指数增长方程。

The results showed that with the increase in the mined area grade of leaf by miners, the photosynthetic rate, stomatal conductance, transpiration rate and stomatal limiting value in castorbean Ricinus communis and kidney bean Phaseolus vulgaris generally decreased. Positive relations existed in the above two crops between different treatment grades and intercellular CO2 concentration variation.

结果表明，随着叶面积受害级别的增高，蓖麻和菜豆的光合速率、气孔导度、蒸腾速率和气孔限制值总体呈下降趋势，不同受害级别与胞间CO2浓度的变化呈正相关。

Result］The results indicated that the photosynthesizes rate, transpiration rate, water use efficiency, stomata conductivity of 3 clones robinia seedlings had the significant difference.

结果］结果表明，3个无性系的净光合速率、蒸腾速率、水分利用效率和气孔导度之间差异明显。
