查询词典 cutoff

First, the S-CDMA-HFC system with integrated traffic is introduced and the method of traffic integration is given. Second, the upstream channel capacity of the S-CDMA-HFC system with integrated traffic that has the same rate is analyzed. The chronoff limit and Gaussian approximate equation of the upstream channel cutoff probability are derived. Third, the impact of the selection of the line transmission rate on the upstream channel capacity of the S-CDMA-HFC system with integrated traffic is discussed in detail. The cutoff probability and throughout equations of the upstream channel with different integrated traffic are derived. Fourth, the impact of the power control error on the capacity is discussed. Results show that the power control error will degrade the upstream channel capacity and have different influence on the different traffic. Finally, the capacity requirement of the initialization process is raised. Analytical results show that the initialization process will impact on the capacity slightly.

The conventional "fundamental" explanation for that cycle relates it to political events. The 1973-1974 oil crisis is said to have been due to the cutoff of oil following the Arab-Israeli Yom Kippur War. The 1979-1981 oil crisis is said to reflect the cutoff in oil due to the Iranian Revolution and the Iran-Iraq war. The drop in oil prices after the mid-1980's is said to be due to the collapse of the OPEC oil cartel.

对这个周期的传统的"基本"解释是将它和政治事件联系起来。1973-1974年的石油危机据说是因为阿拉伯－以色列赎罪日战争之后的石油停产。1979-1981年的石油危机据说反映了因为伊朗革命和伊朗－伊拉克战争导致的石油停产。20世纪80年代中期的石油价格下跌据说是因为欧佩克石油卡特尔的崩溃。

In this paper,the discharge capacity,stability voltage and the ratio of constant current charge capacity and battery discharge capacity of lithium ion battery were studied. For the lithium manganese lithium-ion batteries,the discharge capacity,mid-value voltage and stability voltage all increased with increasing charge cutoff voltage. As long as charge cutoff voltage was no less than 4.15 V,the battery discharge capacity loss would not exceed 6%. When charge cutoff voltage was 4.15V,the constant current charge capacity accounted for more than 85% of total charge capacity,a little change from 4.20 V.
