The distance between the reactive sensor node and the target node is estimated by using the value of RSSI, since the strength of radiation signal and the square of distance is inversely proportional. We proposed a method to derive the position of the target node based on the theory of radical center. With data from three reactive nodes, the position of target node can be analytically estimated.

缓慢松开填料函的压盖螺母，释放盘根组件内所有的残余压力； 2）移去所有旧的盘根，彻底清洁轴/杆的填料函； 3）检查轴/杆是否有腐蚀、凹痕、划伤或过度磨损； 4）检查其他零件是否有毛刺、裂纹、磨损，它们会减少盘根的寿命； 5）检查填料函是否有过大的间隙，以及轴/杆的偏心程度； 6）更换有较大缺陷的零部件； 7）检查旧盘根，作为失效分析的依据，球阀以找到盘根早期失效的原因。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

We selected one axial slice that passed through the upper part of the pedicle and another one that passed through the lower part of the pedicle and compared next parameters in both cuts: pedicular cortical width, pedicular endostal width, pedicular angle, vertebral body length, vertebral body width, vertebral perimeter angles, and visual appearance of vertebral body shape.

我们选择一个通过椎弓根上半部的轴向切片和另一个通过椎弓根下半部的轴向切片，对两个切片进行以下参数的比较：椎弓根皮质宽度，椎弓根骨内膜宽度，椎弓根角度，椎体长度，椎体宽度，椎体圆周角和椎体的外形。

The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.

结果表明：1在研究建立的小麦水培体系中，小麦植株生长正常并对磷饥饿胁迫条件做出发育形态建成水平的反应；半定量RT-PCR分析显示在此体系中小麦磷响应基因也在转录水平上产生显著变化；2在水培条件下不同基因型小麦对磷饥饿胁迫的反应总体上表现在根轴长度和根冠比有所提高，但不同基因型小麦的反应特点有差异；对这些反应特征的分子机理的深入分析可为有效筛选磷高效小麦新种质以及发掘磷高效基因资源提供线索。
