查询词典 application control block

And we have given Hadamard matrix in detail in block design, coding and the specific application in communication., Hadamard code as a nonlinear combinatorial code has catered to the need of development of computer technology, stock systematic data and high speed for realizing and reliable access, request the error control code has not only little redundancy, but also can parallel encoding and decoding with high speed.

Hadamard码作为一种非线性组合码，迎合了计算机技术的发展对实现存储系统数据高速且可靠地存取，要求所采用的差错控制码不但冗余度小，还应当能高速并行编码和译码的需要。

The application results of the N2 injection technology in Guantao reservoir of Du 84 block showed that the N2 injection technology during SAGD process was feasible and beneficial for expansion of steam chamber in sideways and increase of the horizontal sweep volume. N2 injection during SAGD process could effectively control the down flow of top water and lengthen SAGD production time by 3-4 years. Both the reservoir recovery factor and oil steam ratio could be improved.

研究结果表明，氮气辅助SAGD开采技术在杜84块馆陶油层开采中是可行的，有利于蒸汽腔的侧向扩展，增加蒸汽的横向波及体积；在SAGD过程中添加氮气能够有效控制顶水下泄，延长SAGD生产时间3～4年，提高了油藏采收率和油汽比。
