Thus, the paper perfects the 2D linear segment uncertainty ε(subscript σ) model in theory and makes it more scientific, and also provides a new way to study the space data uncertainty in GIS.

本研究完善了2维线元不确定性ε模型，使其更具有严密性，同时为GIS空间数据不确定性的研究提供了新的方法。

The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

运用函数单调性和极值理论，从理论上证明ε模型的误差带的几何特征；得到线元误差带不仅具有&两端大、中同小&，而且也可能具有&一端大、一端小&的几何形状；给出了误差带的最小带宽及其位置；论证了误差带的最小误差带宽的位置靠近中误差较小的一端。

For convenience some geologists prefer to annotate them with a subscript S, for example Ls1 to differentiate them from intersection lineations, though this is generally redundant.

为了方便一些地质学家倾向于注释他们提供一个下标S ，例如Ls1分化他们相交线，虽然这通常是多余的。

Meanwhile, chlorophyll meter and net photosynthetic rate P(subscript n of rice functional leaves were determined, yield and its components were also determined at maturity stages of rice.

选择江苏省宿迁市2个农田林网典型乡镇为样点，按不同方位林带和不同林缘距离，即1/6H、1/3H、1/2H和2H处设置试验样方，于水稻主要生育期，分别观测水稻群体分层的光照度、温度、相对湿度和CO2浓度，同时测定水稻叶片的SPAD值和净光合速率P(下标 n等，并于水稻成熟期测定产量及产量结构。

Intrinsic electron transfer mobilities μ(subscript - of 5.39, 0.59, 0.023, and 0.17 cm^2 were calculated for compounds 1-4, respectively.

Nineteen males with SCI, with the age range of 26~45 years, were included into the study. All patients underwent the B type ultrasound and video-urodynamic examinations to determine the hydronephrosis, post-residual urine volume, detrusor pressure at vesica ureter reflux, detrusor leak point pressure and maximum urethral pressure P(subscript ura.max before and after BTX-A injection.

19例合并肾积水男性SCI患者，年龄26~45岁，治疗前1个月用B超及影像尿动力学检查测量患者肾盂分离宽度、残余尿量、输尿管返流压P(下标 det.reflux、逼尿肌漏尿点压、最大尿道压力P(下标 ura.max等指标。

The scale formed on pure Ti is exclusively TiO2 regardless of temperature, while the scales formed onTi3Al and Ti3Al+TiAl were duplex and always spalled after cooling, consisting of the outer-layer of most TiO2 and the inner-layer of most TiO2, Al2O3, and minor Ti(subscript 1-x)S. The formation of Al2O3 is responsible for the reduction in the corrosion rates of Ti-Al alloys as compared to those of pure Ti.
