查询词典 dual

Recently, many coding experts have studied much of the Z_4-cyclic code(which is not necessarily linear) and its Gray map, and obtained a set of equivalent conditions in which a family of cyclic codes are linear, and the condition that this family codes are self-dual cyclic, and in this condition Nechaev-Gray image of the cyclic codes are self-dual cyclic.

近年来，已有编码学家对Z 4-循环码和Z 4上的映射作了深入研究，得到一类循环码是线性码的一系列等价条件，以及这类线性码是自对偶线性循环码的条件，在此条件下它的Nechaev-Gray像也是自对偶线性循环码。

A simultaneous dual-wavelength continuous wave, quasi-cw or linearly polarized wave diode-end-pumped Nd:YAG laser operating at 1319nm and 1338nm is demonstrated. To the best of our knowledge, our experimental results achieve the highest level in the domestic domain. The simultaneous dual-wavelength laser provides an experimental basis for generating highly coherent THz wave radiation of 3.23THz by nonlinear optical difference frequency method.2. A diode-end-pumped Nd:YAG crystal, type-I critical phase matching LBO crystal intra-cavity frequency doubled, simultaneous multi-wavelength red laser at 659.5nm, 664nm and 669nm is firstly realized.

The SINS of FOG is designed and implemented based on DSP. The system is with a dual CPU structure. DSP is used to process data while MCU controls data acquisition and the communication between DSP and MCU is achieved by dual-port RAM. All of these constitute a small strap-down navigation system. Meanwhile introduced a kind of algorithm of SINS, SPI communication and the second boot Loder of TMS320C6713 in briefly. After testing, the system speed and accuracy satisfy design requirements and the system has been applied to actual system.
