A local suboptimal method of optimal sensor placement(the successive reduce method) based on principle of minimum identification error and try to make interested modal vector linearly independent was introduced.
介绍了一种桥梁结构模态参数测试中传感器优化布置的局部次优方法,也就是逐步消减法,该法基于识别误差最小原则,力求使得感兴趣的模态向量尽可能的线性无关。
Methods: A double-blind randomized study was carried out to compare the treatments of load dosage and tapered dosage benzodiazepines; Alcohol Withdrawal Scale (AWS) and Treatment Emergent Symptom Scale (TESS) were used.
目的 :比较苯二氮 艹卓 类负荷剂量法与逐日递减法治疗戒酒综合征的有效性和安全性。
