查询词典 time-base control

Based on the discrete-time difference equation of the plant,an explicit solution of Diophantine matrix polynomial equations in multivariable generalized predictive control is derived without appealing to Diophantine matrix polynomial equations recursions or iterations,which makes the applications of generalized predictive control much more convenient.

At this time the relay contacts can be seen after the pull-off O5s This shows that ABS control module has control of the relay, as why did it after the pull-bounce, it should be is a system to monitor the failure of the circuit failure protection.

此时可看到继电器触点吸合O5s后断开，这说明ABS控制模块对继电器有所控制，至于吸合后为何又弹开，应该是系统监测到电路故障后的失效保护功能。

At this time the relay contacts can be seen after the pull-off O5s This shows that ABS control module has control of the relay,as why did it after the pull-bounce,it should be is asystem to monitor the failure of the circuit failure protection.The next testing.

此时可看到继电器触点吸合O5s后断开，这说明ABS控制模块对继电器有所控制，至于吸合后为何又弹开，应该是系统监测到电路故障后的失效保护功能接下来的检测工作。

Traditional concurrency control methods constrain the concurrency of transactions and are disadvantageous to satisfaction of Real-Time transactions' timing constraints. We develop a novel quasi-consistent serializable concurrency control strategy. The inconsistency brought by transactions to the system was restricted to an extent.

传统的并发控制策略限制了事务执行的并发度，对实时事务定时限制的满足是不利的，我们开发了一种适合于实时应用环境的新颖的&准一致性可串行化&并发控制方法，事务给系统带来的不一致程度被限定在一定范围内。

This paper proposes a new multimedia transmission mechanism over wireless Internet. Based on the differences in bit error rate and transmission trip time between the wired and the wireless, error control and fading control in wireless Internet are improved....

提出了一种面向无线互联网的多媒体数据传输有效机制，根据有线和无线传输数据所存在的不同位误码率和传输时间响应等特点，改善了有线与无线相结合网络中多媒体传输的差错控制和衰减控制，实验结果证明了本机制的有效性。

Ata28 strain was mutated by UV with the most optimum mutant time, including 10, 20, 30s, that was chosen by the trial tests, considering the lethality rate and positive mutation rate of Ata28; it was found that 15 mutant strains were shown antagonism against Tbs3 strain by antagonism test on PDA plate, inhibition zone of mutant strains exceeded the original strain Ata28, and the maximum of inhibition zone reached 9.4mm; the mutant strain Uv-126 was found most effective in tobacco brown spot control and a rate of efficiency control reached 52.2% on tobacco plants three days after bacteria spraying.
