The microvascular vessels were thin-walled hollow glass fibres with varying diameters up to 680 microns were embedded in the laminate; an example is shown in Figure 1.
As seen in Figure 1, the presence of the hollow fibres increased ply waviness, which in turn reduces the compressive and Figure 1 Cross-sectional view of a composite laminate containing a hollow fibre of 640-micons [5] tensile strengths when above a threshold size.

Fig.1 61 units adaptive optical system Compensation errors analysis Series of errors results from the correction of adaptive optical system to light beam wavefront disturbance, and mainly include the following: Wavefront detecting errors.
Theoretical analysis shows that wavefront detecting errors are inversed of the square of SNR of the detector, and can be expressed as (1) Which is a factor, is signal to noise ratio
