Angular spectral is spectral value map formed by estimating semblable coefficients of fast and slow shear wave or the variation of amplitude ratio of fast and slow shear wave with times and angles at a specified space point based on semblable theory of fast and slow shear wave, the angle value of this space point at a given time can be got by picking the maximum of angular spectral; the study reveals that fast and slow shear wave with different polarization direction should be separated using different rotation formula, eight formulas of separating fast and slow shear wave using clockwise rotation and counterclockwise rotation have been derived, and gained energy assignment rule and phase coincidence rule, in real data estimation, the rotation formula used for separating fast and slow shear wave can be uniquely determined on the two discriminating rules.

An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

Eschatology concerns antinomy in blessing and cursing, destroying and producing, and attributes the destructive time to man's original sin, which will lead to the end of the world. Meanwhile, eschatology combines the cyclical time with religious pilgrimage, thus bringing forth the function of production and creation, and moreover, assumes that time is in a state of spatialization during the chaotic period of creating a new world or a new age.

末世论&赋予时间以祝福和诅咒、摧毁和催生的基督教二律背反特征，将时间的线性运动所带来的摧毁性质归咎于人的原罪，并认为原罪所生发的邪恶时间导致了世界末日的来临；与此同时，&末世论将时间的圆形运动与宗教朝圣联系起来，形成了时间的催生和创世功能，而在创世的混沌时刻，时间的表现形态则是空间化的。

First, the effects of magnetic RAM relaxation time and the rise-time of incident pulse signal on reflection signal are discussed, the relationship between the rise-time of incident pulse and relaxation time based on the energy of reflection signal is revealed. Then, the effects of magnetic hysteric, susceptibilities and saturation upon reflection signal are analyzed, the results reveal the reflection of RAM target and UWB signal design. In the meantime, dielectric relaxation time effect about dielectric RAM target is analyzed simply, and the effects of relaxation time and the width of incident pulse upon reflection signal are probed. Finally, a few RAM targets are measured in the chamber using the impulse radar experiment system which is developed by the team of anti-stealth impulse radar on Department of Electrical Engineering, National University of Defense Technology. The experimental results show the similarity of the rule of echos with the theory. From the compared results of different tagets, we concluded, compared with 15% wideband sinusoidal signal, the impulse signal has increased 10～12dB energy from the same loaded RAM target; this, in turn, shows the nonlinear effects of RAM to the echoes, and the potentiality of the impulse signal to RAM targets.
