查询词典 peak

The low-temperature peak corresponds to the minimum of relative dynamic modulus and is attributed to elastic modulus softening effect caused by the anelastic motion of the phase interface. The high-temperature peak corresponds to the inflexion point of relative dynamic modulus and the volume change produced by the normal motion of the phase interface is responsible for the peak.

The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

结果表明：度销磨损表面主要呈现犁沟型、孤岛型及二者的混合型3种形貌特征，其中具有孤岛型磨损表面形貌特征的试样的摩擦系数较高，磨损率较低；而具有犁沟型磨损表面形貌特征的试样的摩擦系数最低，磨损率最高，分析表面形貌参数发现：犁沟型表面形貌具有最大的表面高度偏差和表面空隙率及高负值的表面高度分布参数；而孤岛型表面形貌的表面高度偏差和表面空隙率最小，表面高度分布参数为高正值。

通过实验分析了这些参数之间的关系，从而得出了静电放电的一些规律以及这些参数对静电放电辐射场的影响。

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.
