介绍 PGC3 0 2在线气相色相谱仪因原进口色谱柱劣化，换用国产色谱柱后，在调试过程中，样品压力、恒温箱温度、载气流量、测量周期长短、样品各组分保留时间的确定，采样、柱切、反吹、平衡阀门开关时间的改变对测量分析的影响及解决办法。

Results showed a high-purity and a good-integrity DNA can be obtained from the preserved fresh leaves of Camellia azalea, using the methods of modified CTAB and SDS subarea. The DNA extracting quality from the leaves preserved with silica gel by the methods of modified CTAB and SDS subarea is high, which is the same as from the leaves preserved at the -200C and liquid nitrogen, So these preserving methods are suitable for the fresh leaves of Camellia azalea, including for it from distant place.

结果表明，改进的CTAB和SDS区室法都适合杜鹃红山茶基因组DNA的提取，都能提取到完整性较好、纯度较高的基因组DNA，且在采用的-200C、液氮、硅胶脱水干燥3种方法保存样品中，硅胶脱水干燥法保存的样品与其它几种方法保存的样品一样，提取获得了高质量DNA，为远距离采样提取杜鹃红山茶DNA提供了一种较好的鲜叶保存方法。

It should be noted that for signal processing applications, it is imperative that the frame synchronization signal from the TMS320C5x/C54x will provide equidistant sampling.
