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。

There is much noise in the state of eyes opening unforcedly, so the noise processing is necessary, the upper and lower eyelids are removed by parabola fitting, the facular is removed by neighboring gray average, the eyelashes are removed by finding all the candidate eyelashes by local gray minimum firstly, then the false eyelashes are removed by the beginning location, directional and length information of the eyelashes.

在人眼自然睁开状态下存在噪声，因此需要进行去噪操作：通过抛物线拟合的方法去除上、下眼睑；利用邻域灰度均值法去除光斑；去除眼睫毛时先用局部灰度极小值的方法找到所有候选眼睫毛点，然后利用眼睫毛的起始信息、方向信息和长度信息去除伪眼睫毛点。

From 1957 to 1963, the design team went through at least twelve iterations of the form of the shells trying to find an economically acceptable form (including schemes with parabolas, circular ribs and ellipsoids) before a workable solution was completed.

Nitrate (NO3--N) showed a single hump-shaped curve with soil depth increased, but ammonia (NH4+-N) showed a parabola curve, with lowest value found in 20-40 cm soil layer and highest value in 0-20 cm and 40-60 cm soil layer.

油松林土壤全氮和有机质含量垂直变化趋势相似，随土壤深度的增加而降低；硝态氮(NO3--N)均随土壤深度的增加呈单峰曲线变化趋势，而铵态氮(NH4+-N)随土壤深度增加呈先降低后增加的抛物线趋势。

In order to design optimum nozzle for air-air missile solid rocket motor, the mass model of solid rocket motor, the nozzle specifice impulse model of solid rocket motor and the objective function are established. Five different type of nozzles are choosen lor calculation: Conical, parabolidal,two different arcs,quadiatic polynominal and cubic polynominal.
