  target component
     The procedure consisted of several steps: first,background correction was performed from the original data,and then the target component spectrum was multiplied by the projection matrix of the standard component spectrum,finally,cosine value between target component spectrum and its projected residue was applied as a criterion to test the peak purity of target component.
     对背景进行扣除后,用对照组分光谱构建正交投影矩阵对目标色谱峰的光谱进行投影,以目标色谱峰投影后的残余光谱与投影前的原始光谱的夹角余弦为判据鉴别目标色谱峰的峰纯度。

  target component
The interactions depending on the impact parameter (which is characteristic of the target component) are investigated.
      
Assuming a linear background, the target component, which can be a small group of components, is simultaneously determined together with co-existing components.
      
Experiments 2, 3 and 4 suggested that affordances of an irrelevant main body of an object influences motor planning processes only when the local target component of the object is analysed as a meaningful part of a graspable object.
      
Many extracting solutions and extraction sequences can be found in the literature and the abilities of any given extracting solution to solubilise a target component of a soil/sediment system is much debated.
      
The mass flow of the target component measured as the permeation rate was determined via the quasi-continuous observation of the loss in the permeation tube mass during the measuring time.
