The sharpest controversy is over proposed drilling on public land on the Roan Plateau, a 200-square-mile (518 square km) area near Parachute that is still relatively wild.

在Roan高原的公共用地上钻孔的提议引发了最激烈的辩论，这是一块200平方哩（518平方公里）的土地，靠近Parachute，仍然保留着原始地貌。

Unto Oct. 1, 2008, 162 ripe fruits were picked and 43 of fruit bearing from the tomato plants in large cultivated pool; the plant canopy area was about 10 m^2, and rootstalk was 26.68 mm, the tomato grew well.

到2008年10月1日，大栽培池番茄植株累计采摘成熟果162个，挂果43个；其冠层面积约10 平方公尺，根茎直径为26.68 mm，番茄长势良好。

Proton generated from a Cockroft-Walton accelerator in the energy range of 30-100 keV were appropriately collimated and made to pass through a 10 g/cm^2 carbon foil. After Rutherford scattering, proton uniformly irradiated TLDs which were placed at the 20° behind and 20 cm away from the carbon foil. We used a channeltron behind TLD holder as the proton detector.

由Cockroft-Walton加速器提供之质子源，能量在30~100keV间，经准直后通过一10 g/平方公分之碳膜做拉塞福散射，散射后之质子均匀打在置於其后20°的压克力置装器内的热发光剂量计，利用压克力置装器后之一电子倍增器作为量测质子工具。

The space-like hypersurfaces with constant scalar curvature in a de Sitter space were studied and a pinching theorem on the square of the norm of the second fundamental form was obtained.

研究de Sitter空间中具有常数量曲率的类空超曲面，将Cheng-Yau的自共轨运算元口作用在对称张量T上，得到了这类超曲面关於第二基本形式模长平方的一个拼挤定理，加强了已有的相应结果。

The impregnated cathodes with sub-micron scandia doped tungsten matrix exhibited excellent emission property. The current densities of more than 30 A/cm^2 at 850℃ b could be obtained, and the emission homogeneity was improved with the ordinary scandate cathode.

湿法冶金方法制备的亚微米结构钪钨基扩散阴极850℃时电流密度可达47A/平方公分，且阴极表面的发射均匀性较普通钪酸盐阴极有明显的改善。
