    • A preparation method of labeled DNA and use thereof are disclosed. More specifically, the invention relates to a preparation method of labeled DNA by preparation of a complex triple-stranded DNA through an deoxyoligonucleotide complementary to the deoxyoligonucleotide sequence of the 3′ terminal sequence of a certain double-stranded DNA followed by replacement of the 3′ terminal region of the plus strand of said double-stranded DNA with at least one labeled dNTP, and also to said immobilization method of a DNA obtained from the preparation method of the labeled (or modified) DNAs onto a solid support. These subject matters are mainly useful for preparation of labeled DNA molecules.
    • 公开了标记DNA的制备方法及其用途。 更具体地说,本发明涉及通过与特定双链DNA的3'末端序列的脱氧寡核苷酸序列互补的脱氧寡核苷酸制备复合三链DNA,然后更换3'末端的标记DNA的制备方法。 所述双链DNA的正链的末端区域与至少一个标记的dNTP,以及所述从标记(或修饰的)DNA的制备方法获得的DNA固定在固体支持物上的固定方法。 这些主题主要用于制备标记的DNA分子。

    • A system measures the positions of bit errors in digital recording devices and displays the physical locations of the bit errors and their distribution in such a manner that they can be grasped visually and intuitively. The system compares a data stream to be measured with a correct data stream and measures the bit errors. The apparatus includes a data stream memory which holds the correct data stream, a comparator, a counter which totals the number of bit errors, a measured bit number counter which totals the measured data stream and determines the boundaries of the logical recording blocks of the recording medium, an error number memory which holds the number of errors in each logical recording block, and an error address memory. The physical locations of bit errors are calculated on the basis of the measured and recorded bit error information for each logical block, and the bit error information is displayed on the physical form of the recording medium.
    • 系统测量数字记录装置中位错误的位置,并以可视和直观的方式显示位错误及其分布的物理位置。 系统将要测量的数据流与正确的数据流进行比较,并测量位错误。 该装置包括保存正确数据流的数据流存储器,比较器,总计位数错误的计数器,测量的位数计数器,其总计测量的数据流并确定记录的逻辑记录块的边界 介质,存储每个逻辑记录块中的错误数的错误数存储器和错误地址存储器。 基于每个逻辑块的测量和记录的位错误信息来计算位错误的物理位置,并且位记录信息显示在记录介质的物理形式上。
