dc-x

Definite diagnoses of dextrocardia ( DC) were derived from X-ray examination, including thoracic-abdominal plain X-ray film, hilar computed tomography, high kV chest plain film or ultrafast CT, echocardiogram and angiography.

主要根据X线检查（胸腹平片、肺门断层片、高千伏胸片、超高速CT）、超声心动图、心导管检查明确诊断。

With the arrangement y ( zz) x, the intensities of four Raman lines were obviously changed under the action of a DC field with opposite sign to that of the crystal polarity.

在y（zz）x配置下，施加异号电压时，四条谱线强度都发生明显变化。

Second, a new method of controlling chaos by employing a dynamical nonlinear controller is developed to DC-DC buck converters towards stead periodic orbit. The controller is piecewise-quadratic function in the form of x x.

基于一种分段二次函数xx，提出了一种新的混沌控制方法，使用它作为非线性反馈控制器成功地控制了DC-DC buck变换器到稳定的周期轨道。
