查询词典 negative complex

The fusion between the mutually contradicted forms of to sell and to buy the arbitrage. Their combined proposition, the dual arbitrage is the negation of the negation. Deducted by analogy, when summarizing all the trading forms, we can find that they all conform to the trinity philosophy of Hegel. As Marx said,"In Greek, this is the positive, negative and combined proposition. And to those readers who cannot understand Hegel"s language, we tell them a holly formula: positive, negative and the negation of the negation. All these trading forms follow the principles of the change of quantity and quality, the contradictive unification and the negation of the negation.

我们把套期保值交易看作正题，那么，卖出套期保值是肯定一一买入套期保值是否定，这两个包含在反题中的对抗因素的斗争，形成辩证运动；卖出套期保值和买入套期保值就可以互相转化；这两个彼此矛盾的交易，形成新的合题，就形成一个新的交易形式，即卖出套期保值和买入套期保值这两个彼此矛盾的融合，它们的合题——双向套期保值是否定之否定。

The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

Aimming at the fuel control requirement of micro-turbojet,the automobile's electric fuel pump with adaptable improvement is chosen as fuel-feed system.The performance of fuel pump and the technical difficulty of flux control as the speed of pump doesn't be measured are analyzed.Using Philips 83C552 MCU as the main control chip,the system adopts voltage negative feedback combined current compensation instead of rotation speed negative feedback and a PWM convertor to design the flux closed loop control system.
