A method for detecting a SNP site on a SMA gene is disclosed, and includes steps of: (S) performing a PCR for amplifying a nucleic a nucleic acid fragment containing a SNP site; (S) performing a dephosphorylation reaction on the nucleic acid fragment; (S) performing an extension reaction on the nucleic acid fragment, wherein the SNP site is identified by using an extension primer, a 3'-end of the extension primer is extended by a single nucleotide which is complementary to a base of the SNP site, and thus an extended extension primer is obtained; (S) performing a purification reaction; and (S) measuring a molecular weight of the extended extension primer, and determining a type of a base of the single nucleotide based upon the molecular weight, thereby determining whether deletion occurs to the SNP site.

A power control apparatus and method for an optical drive is disclosed. The power control apparatus estimates the temperature rising effect of a laser diode and performs a partial open-loop power control, achieving accurate write power control. Therefore, regarding to a high-speed, high-density optical disk recording medium combined with multi-pulse write waveforms, the invention can also achieve accurate write power control even though the response speed of a front photodiode is much slower than the modulation speed of recording pulses of the laser diode.
