Wang et al. [1] proposed an interpolating method for pulses uniformization, and Q.
Ye et al. [5], which leads to the arcing at crossing points and the velocity unstable, the accuracy decreased.
If there is an interpolating spare el∆ at the end of the interpolating segment, all the interpolation steps remain the same except that Eq.1 is corrected by iel∆ = ∆S .

Sharma et al. investigated different solar dryers suitable for fruit and vegetable drying and concluded that cabinet-type natural convection solar dryer was very suitable to drying small quantities of fruit and vegetable on the domestic scale, and indirect-type multi-shelf dryer was suitable for use on a large scale by industries [1,2].
An indirect type natural convection solar dryer, consisted of a cabinet and a flat plate air heater designed to be able to insert various storage materials under the absorber plate, was constructed and experimentally investigated by El-Sebaii et al. [8] who found that the use of storage materials (such as sands) and chemical pretreatment made the drying time of all the investigated crops shortened greatly.
For indirect solar dryers, the performance of air collectors would significantly influence their drying performance, and an experimental study conducted by Sharma et al. showed that the V-corrugated collector was the most efficient and the flat plate collector was the least efficient for three types of solar air collectors to be investigated [9].

According to Velez et al. [9], the weight loss of lithium borate glass was found varied linearly with time.
The shift band in the region 1200cm-1-1600cm-1 means that BO3 units are assumed to be removed from phosphorus atoms (no B-O-P linkages) as reported by Elbers et al. [14].

These peaks confirmed the transformation of the primary α-Al dendrite, binary eutectic Al-Si eutectic, and ternary eutectic Al-Si, Al2Cu, respectively.
Consequently, the solidification sequence of Al-5.7Si-2Cu-0.3Mg alloy can be described as: L→α-Al dendrite phase → Al-Si binary eutectic → Al-Si-Al2Cu ternary eutectic.
The eutectic Al-Si phase with nearly spherical primary Si particles is well distributed within the Al-matrix [25], [26].
The eutectic Al-Si phase, with nearly spherical primary Si particles, is distributed in the Al-matrix [30].
