With the increasing of Pb and Cd concentration and the prolongation of the time, the net photosynthetic rate, stomatal conductance, transpiration rate of all hybrid tulip trees decreased and the downtrends of NE60 and NEF14 which were stress- resistence were small. But the changes of intercellular CO2 concentration were difference.

在Pb、Cd胁迫下，杂交鹅掌楸净光合速率、气孔导度和蒸腾速率均随胁迫浓度的增加和胁迫时间的延长而下降，且抗性较强的NE60、NEF14降幅较小，而胞间CO2浓度随浓度和时间变化各杂交鹅掌楸变化存在差异。

With the prolongation of the time of Pb and Cd stress, the chlorophyll content of the clones and families were induced to first increase and later decrease, except that NEF14 and NEF12 were downtrend at all times. With the increasing of Pb and Cd concentration the chlorophyll content decreased fastly in the latter stress period. The downtrends of NE60 and NEF14 which were stress-resistence were small.

随胁迫时间的延长，杂交鹅掌楸无性系和家系(但NEF14和NEF12一直呈下降趋势)的叶绿素含量先升后降，随着Pb、Cd处理浓度增大，在胁迫后期叶绿素含量下降越明显，抗性较强的NE60无性系、NEF14家系降幅较小。

结果表明，秦岭南坡土壤肥力指标在整个土壤剖面空间分异范围分别为：土壤pH值5.97～6.89，有机质含量6.6～50.1 g·kg-1，土壤全N含量0.5～3.8 g·kg-1，碱解N含量33.6～257.3 mg·kg-1，速效P含量0.81～5.8 mg·kg-1，速效K含量38.9～262.4 mg·kg-1，粘粒含量11.3%～18.1%，阳离子代换量68.5～310.2 mmol·kg-1；其空间分异程度以速效P、有机质和土壤全N含量较大，土壤粘粒含量和土壤pH值较小；随着土层的加深，土壤pH值、有机质、速效P、土壤粘粒含量和阳离子代换量空间分异程度减小，而土壤全N、碱解N和速效K含量空间分异程度增大。

2Among different nationalities,the difference of gene frequency of Mongoloid fold , Nasal profile, Hair forms and Eye fold of the upper eyelid was quite significant, which was followed by that of Nostril forms.

内眦褶、鼻梁侧面观、发型和上眼睑皱褶的基因频率在民族间差异较大，而鼻孔形状则较小。

ESO 550-2 shows a pair of spiral galaxies, the larger nearly face-on and accompanied by a smaller, highly tilted partner.

ESO 550-2展现了一对漩涡星系，一个较大的几乎面对我们的和一个较小的高度倾斜的星系。

Comparison of case calculations indicates that different site sets may require varied methods to construct optimal grids. Among them the "optimized dynamic allocation under flattest model constraint", and "optimized dynamic allocation under smoothest model constraint" are most adaptive, by which the constructed grids have fairly smooth grid spacing and smaller site shifts.

算例对比研究表明，对于不同的测点集，最佳网格构建的方法可能不相同，但其中&最平模型约束动态配点法&、&最光模型约束动态配点法&拥有最强的适应能力，它们在各种情况下所构建的网格一般同时具备较光滑的网格间距变化和较小的测点偏离程度。

The peak viscosity of wet milling flour are greater than that of dry milling but the peak time and pasting temperature of wet milling flour are lower than that of dry milling.

不同品种玉米面粉的峰值时间和糊化温度变异系数较小，其他糊化参数的变异系数较大。

Therefore, for improving the accuracy of exceed slender axle on turning,must need to do with the lathe fixture and cutting tool for further improvement. In order to reached the requirements of precision machining,in machining process must use follower rest、flexible active thimble、space block and bracket etc fixture and assistive device.

超细长轴在车削加工中承受自身重力、切削力、高速旋转产生的离心力的作用，极容易出现振动与弯曲变形现象，增大轴的几何形状误差，而超细长轴的轴向尺寸较大，直径较小，热扩散性及刚性差，受切削热作用会在轴向发生线性膨胀，若在轴向的伸长量无法得到消除，轴将受迫弯曲，从而影响轴的精度。
