人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。

The results indicated that the earth's surface temperature and air temperature of the desert comparing the oasis of the variety range are higher and ascend and descend of the speed are quicker; As the ascend and descend changes of air relative humidity and temperature are different at each observation spot, the variety curve of the air pressure of daytime shows the single type of wave; At each observation spot the predominant direction of wind was mainly souther, still having the southeast or southwester at 12:00-18:00; Wind speed almost is 0 at 20:00; The clean radiation at the morning and the evening of desert are higher than in oasis, the clean radiation in oasis in the daytime is bigger than in desert.

结果表明，沙漠地表面温度和气温升降速度比绿洲观测点要快、变化幅度大；由于各观测点空气相对湿度和温度升降度不同，使得各观测点的气压升降幅度也不同，白天气压的变化曲线呈单蜂型；各观测点在12：00到18：00期间主导风向主要是南风，还有东南或西南风，在20：00时风速几乎为0；早上和晚上沙漠的净辐射高于绿洲，白天近地面净辐射绿洲大于沙漠；对绿洲气象要素时空效应特征分析，为棉花等绿洲优势作物的播种期、物候期、作物生育及生理生态特性具有一定的指导意义。

It shows that the Taiwan topography influence on the movement and the central air pressure is salience. The topography force influence on the typhonic central intensity and unsymmertrical structure is very evident. The Taiwan topography is the primary reason for the low pressure in the windward mountain and high pressure in the leeward mountain. The topography is the primary reason for the peripheral precipitation reinfor4ce of the typhoon.

试验结果表明：台湾岛地形对台风&泰利&的移动路径和中心气压的影响不显著；地形的强迫作用对台风涡度场的中心强度和非对称结构有明显的影响；台湾岛地形是形成迎风坡诱生低压和背风坡诱生高压的主要因子；地形是台风外围降水加强的主要原因。

The large area of desert without Vegetation cover is widely distributed in Minqin County and its vicinity, which makes up a region of high temperature and low pressure owing to the desert where significant air pressure gradient is raised with cold high pressure from the west Siberia dispreading towards the south of China.
