This thesis describes a 29GeV electron - nucleon scattering experiment carried out at Stanford Linear Accelerator Center (SLAC). Highly polarized electrons are scattered off a polarized ND{sub 3} target. Scattered electrons are detected by two spectrometers located in End Station A (ESA) at angles of 4.5{degrees} and 7{degrees} with respect to the beam axis. We have measured the spin structure function g{sub 1} of deuteron over the range of 0.029 < x < 0.8 and 1. 0 < Q{sup 2} < 12.0(GeV/c){sup 2}. This integral indicates a discrepancy of more than three standard deviations from the prediction of the Ellis-Jaffe sum rule, 0.068{+-}0.005 at Q{sup 2} = 3.0(GeV/c){sup 2} while our result of g{sub 1}{sup d} in good agreement with SMC results. Combined with g{sub 1} of the proton, the measurement of {integral}{sub 0}{sup 1}(g{sub 1}{sup d}-g{sub 1}{sup n}) is 0.169{+-}0.008. We also obtained the strong coupling constant at Q{sup 2} = 3.0(GeV/c){sup 2} to be 0.417{sub -0.110}{sup +0.086}, using the power correction for the sum rule up to third order of {alpha}{sub s}. This result is in agreement with the strong coupling constant {alpha}{sub s}(Q{sup 2}) = 3.0(GeV/c{sup 2}) obtained from various experiments. Using our deuteron results and the axial vector couplings of hyperon decays, the total quark polarization along the nucleon spin is found to be 0.286{+-}.055, implying that quarks carry only 30% of the nucleon spin. The strange sea quark polarization is also determined to be -0.101 {+-} .023. These measurements are in agreement with other experiments and provide the world`s most precise measurement of these quark polarizations. 80 refs., 151 figs., 23 tabs.

X‐ray time series data from the 4.8‐second binary pulsar Cen X‐3 observed with Ginga are analyzed. We study the fractal dimension of x‐ray intensity of the total 1.7∼37 keV energy band. The fractal dimensions of the temporal behavior on time scales ≥4.8 seconds are comparatively large. It implies that the source varies with small size perturbations compared with the scale of the system. The effect of noise on the fractal dimension is estimated briefly. It is mentioned that there exists a low dimensional motion with the time scale of 500 s.
本文分析了用Ginga观测到的4.8秒双星脉冲星Cen X - 3的X射线时间序列数据。我们研究了1.7 ~ 37 keV总能带x射线强度的分形维数。时间尺度≥4.8秒时，时间行为的分形维数较大。这意味着与系统的尺度相比，源随着小尺度的扰动而变化。简要估计了噪声对分形维数的影响。文中提到存在一个时间尺度为500s的低维运动。
