A piezoactuator has multilayer construction. A solution of battery active metal cations and reactive anions may be blended with a fuel to yield a precursor mixture usable for synthesizing a battery active material for deposition onto a substrate. The first clock and the second clock are not synchronized. The valve in is fluid communication with the suction port and the inner cavity of the cup member to modify the suction therebetween. Firstly, in step, a plurality of digital signals are received through a path memory module of the Viterbi decoder with decoding an input signal; in step the received digital signals in step are compared with a default number; and in step, an output according to the comparison result provided by step is determined. The instrument can measure the two-dimensional angular optical scattering andor the one-dimensional angular optical scattering at one or more wavelengths.
