查询词典 symptom complex

The curve length of the QRS complex is longer than that of other parts of the ECG in the same interval, so that the ECG curve length characteristic is suitable for QRS dctcction. Our algorithm not only detects the QRS complex position but also its duration.

该算法根据QRS复合波的曲线长度在一定的等时间间隔内大于ECG其他部分的特性进行QRS波的信息提取，其不但检测QRS波的位置，而且同时检测出QRS波的宽度。

Quadratic phase coupling analysis is extended to complex domain in this chapter,〓-D spectrum method is adopted to obtain the coupling and coupled components separately by using different cumulant definitions of complex process. This property can be used to avoid confusion when multigroup quadratic phase coupling relationships are involved.

It is reported in this paper that diphenylcarbazone reacts with Hg in pH 2.2 in the presence of Tween─60 to form a purple complex with its absorption maximum at 486 nm. The existence of chloride will depress the absorption of the complex. The negative absorption will be proportional to the consistence of chloride.

摘要﹞ 在pH为2.2的酸性介质中，在吐温－60溶液的存在下，Hg与二苯卡巴形成紫色的配合物，其最大吸收波长为486 nm，氯离子的存在可使原紫色配合物吸光度降低，其负吸光度与氯离子浓度成正比。
