The algorithm uses the RF packet only to obtain the distance differences between unknown node and beacon nodes. Then the algorithm figure out the node"s coordinates by the improved trilateration to implement the long distance, controllable accuracy, low-cost localization. Second, this paper proposes a distributed Kalman algorithm to optimize the TDOA"s error.

算法的基本思路是直接利用无线通信模块的射频分组求得未知节点到各个信标节点的距离之差，然后利用改进型的三边定位法计算出节点的坐标，对节点实施远距离、精度可控、低成本的定位。

serum psa levels were detected by chemiluminescent immunoassayin 65 patients with prostate carcinoma and 116 patients with benign prostatic hyperplasia.

采用化学发光免疫分析法检测前列腺癌患者(65例)和前列腺增生患者(116例)血清psa水平，同时利用b超测定患者前列腺体积，计算出psad值，对患者进行分组比较。

Methods By simple randomization, divided 77 diabetics into two groups: the control group include 37 subjects taking vitamin B1 and vitamin B6, the other group include 40 subjects taking the prescription with milk vetch etc, to find the changing of MDNS by concurrent randomized control.

采用半随机法分组，37例对照组，给予维生素B1、B6治疗，40例为治疗组，给予黄芪等中药方剂。以密歇根糖尿病神经病变记分变化程度作为观察指标，用同期随机对照的研究方法观察两组的治疗效果。
