When you integrate in polar coordinates, you just set up your bounds in terms of r and theta, dA but you replace dA by r dr d theta, not just dr d theta. 当你在极坐标系下积分时,你不仅要建立关于r和θ的界限,而且要用rdrdθ,而不是drdθ来代替。
After its basic ideas and implementation architectures are given, several key techniques involved in DRD are discussed in regard to the design and implementation of a DRD prototype system. 在介绍DRD的基本思想和实现结构以后,结合一个DRD样机系统,讨论了DRD所涉及的关键实现技术。
Conclusions Clinical diversity and diurnal fluctuation are the characteristics of DRD. 结论DRD患者具有症状多样及日间波动的特点。
Conclusion The clinical manifestations of DRD are various and they are closely correlated with age. Conclusion Clinical manifestations of patients with sarcoidosis of the nervous system are varied. 结论多巴反应性肌张力障碍临床表现呈多样化,临床表现与年龄密切相关。结论神经系统结节病的临床表现多种多样。
Methods Systematic study of clinical features, diagnosis and therapeutic effect in 10 patients with DRD was performed and retrospectively analyzed. 方法回顾性分析10例多巴反应性肌张力障碍患者的临床表现、诊断方法和治疗效果。
Objective To study the clinical characteristics of patients with dopa-responsive dystonia ( DRD). 目的研究多巴反应性肌张力障碍患者的临床特点。
DRD ── Design of a Diagnosis Based on High Reliable Distributed Computer Systems DRD&基于诊断的高可靠分布式计算机系统的设计
Methods Sixteen familiar DRD patients and 10 patients with sporadic DRD were studied by history taking, physical examination of nervous system and CT/ MR scaning. The obtained data were statistical analyzed with SPSS 13.0 software in computer. 方法对16例家族性患者和10例散发性多巴反应性肌张力障碍患者进行病史采集、神经系统体格检查和CT或MRI检查,所得数据应用SPSS13.0软件进行统计分析。
OBJECTIVE: To analyze the relationship between Chinese DRD onset and gene mutation of guanosine triphosphate cyclohydrolase 1 ( GCH 1). 目的:分析国人DRD患者发病与三磷酸鸟苷环化水解酶1(GCH-1)基因突变的关系。
