查询词典 negative

Firstly the fuzzy entropy in quadratic form is modified by substituting standard negative operator of Zadeh with generalized negative operator of Sugeno, and the generalized fuzzy entropy formula is obtained.

首先将Sugeno广义否定算子替代二次型模糊熵公式的Zadeh标准否定算子，得到了参数型的广义模糊熵表达式；其次，将其应用于构造图像阈值化分割的准则函数；最后，给出了图像阈值化分割新算法中的广义模糊熵参数自动选取方法。

By combining the {spdf} interacting boson model and the Eikonal approximation theory, we proposed an approach descibing the inelastic scattering in which the nucleus is excited from the ground state to a negative parity state by the medium energy hadron. In this scheme it is easy to determine the deformation parameter of the collective excited state with negative parity, the form factor and the scattering cross section.

通过把{spdf}相互作用玻色子模型和Eikonal近似理论相结合，我们提出了描述中能强子使核激发到负宇称态的非弹性散射的方案，给出了负宇称激发态的形变参数及散射的形状因子和散射截面。

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.
