The flowmeter designed in the past couldnt decrease the consumption so low that the whole system can be supplied by dry battery.

以前的单表型流量计都无法降低功耗到足以用干电池供电，最多只是采用蓄电池供电。

In the JTB series Roots blower developed by Chongqing Chuangu electromechanical equipment Co., Ltd, the single oil base is changed the dual oil base, this avoids to burning bearing by lubrication no good. The check valve and T-joint are designed into one, this simplifies the installation process and avoids to some troubles. The more important is that all parts of the rotor are the overall, this greatly increased the stiffness and received by the market.

重庆川鼓公司研发设计开发出JTB系列罗茨风机，将单油箱改变成双油箱，从而避免了因润滑加不及时或不到位而烧轴承的现象；将单向阀与T型接口设计成一体，简化了安装工序，克服由此引发的故障；更重要的是全部转子部件采用整体结构，大大提高了刚度，因此受到市场欢迎。

Direct sequencing of DNA amplified by PCR was used with the primers designed according to the sequence of control region and the neighbor region. Sequences were analyzed and compared base on Sequencing Analysis 3.4 and Seq/Ede software. DP of mtDNA in Yao ethnic group was calculated. MAGA2 software was also employed to analyze the genetic distance between samples and construct the phylogenentic tree.

以南方民族瑶族为研究对象，根据mtDNA控制区及周围区域的序列设计引物，用PCR产物直接测序对105份无关瑶族样本mtDNA控制区进行了测序，通过Sequencing Analysis 3.4和Seq/Ede软件分析比对，得到的序列结果，计算瑶族mtDNA单倍型的识别率，并应用MEGA 2软件对数据做进化距离分析，构建系统发育树。
