The spectrum characteristics of turbulence such as period of fluctuation, frequency and amplitude of oscillation were discussed by using the method of spectral analysis of turbulence in this paper. The results show that the spectrum density in the range of low frequency is sharply variance with the distance from the windbreaks, but it follows the power index law of -5 / 3 and satisfies the theory of local isotropic turbulence in the range of high frequency. It also shows by connecting with Eulerium autocorrelation analysis that there are small scale,high frequency and short period of turbulence near the lecsidc of windbreaks,but often large scale, low frequency and long period of turbulence far from the windbreaks.

The sulfatc soap is refined through extracting unsaponifiable neutral substance using ethyl acetate and hcxane-acetone. The content of neutral substance in tall oil decreases from 32.8% to 17.4% and 18%. The acid number of tall oil increases from 119 to 169 and 153. The quality of tall oil is greatly improved. This provides a favorable condition for distillation of tall oil. The unsaponifiable neutral substance from crude sulfate soap mainly consists of tcrpene aldehydes, tcrpcnc alcohols, fatty alcohols and stcrols in which larixol is 26.3% and 18. 5%, stcrols arc 17% and 27.1% separately. The white crystals containing stcrols of 96.9% are obtained by crystallization and rccrystallization. The stcrols arc mainly β-sitostcrol and campcsterol.

Cuprous and molybdic oxides exhibit extremely effectiveness in smoke suppression for PVC. However, few are the data reported concerning flame retardance and smoke emission of PVC taken from Cone calorimetry relative to the conventional thermal analysis technique. Abundant data from Cone calorimetry have been acquired. Data analysis was achieved through the study of MLR, HRR, SEA tested at irradiance of 25 kWm -2 . The understandable flame retardance of PVC/Cu\-2O and PVC/MoO\-3 relative to pure PVC has been rationalized by their lowered heat release rates and enhanced char residues. The difference in smoke reduction between these two oxides consists in the time scale. As clearly seen under air atmosphere both oxides exert themselves to the afterglow which has been recognized as a dangerous source, in particular in the full_scale fire situation.
