First, the S-CDMA-HFC system with integrated traffic is introduced and the method of traffic integration is given. Second, the upstream channel capacity of the S-CDMA-HFC system with integrated traffic that has the same rate is analyzed. The chronoff limit and Gaussian approximate equation of the upstream channel cutoff probability are derived. Third, the impact of the selection of the line transmission rate on the upstream channel capacity of the S-CDMA-HFC system with integrated traffic is discussed in detail. The cutoff probability and throughout equations of the upstream channel with different integrated traffic are derived. Fourth, the impact of the power control error on the capacity is discussed. Results show that the power control error will degrade the upstream channel capacity and have different influence on the different traffic. Finally, the capacity requirement of the initialization process is raised. Analytical results show that the initialization process will impact on the capacity slightly.

Because the fish drying Shrinkage small Shrinkage crack surfaces, more in Water, so the bibulous rate of early (see figure 4) soon, absorbing ability, 1.2 m in bibulous rate (Water absorption Measurement can reach 1 36), In the early EHD water are slower, bibulous rate in 30 m in later, when the water absorption speed enough time to also can achieve higher bibulous rate and natural drying EHD with dry bibulous rate basic same, in addition, natural drying and EHD dry fish good water resistance, 120 m in water can still keep complete shape after drying fish, but by 120 m in pieces after absorbing began.

由于热风干燥鱼的收缩率较小、表面有较多缝隙，所以在吸水初期的吸水速度很快(见图4)，吸水能力很强， 120 m in 吸水率可达到1。 36； EHD在吸水初期的吸水速度均较慢，在30 m in以后吸水速度加快，当吸水时间足够时也能达到较高的吸水率，自然干燥与EHD干燥的吸水率基本相同，另外，自然干燥和EHD干燥鱼的耐水性好， 120 m in 吸水后仍能保持完整形状，而热风干燥鱼经120 m in 吸水后即开始溃散。

Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

The model correctly predicted and explained the effect of cooling rate and warming rate on the intracellular ice formation during the cooling and warming process. The cooling and warming rate which can realize vitrification and avoid devitrification was gained. This is to say, when the cooling rate is not less than 400℃/min and the warming rate is not less than 500℃/min, intracellular ice formation can be avoided.
