The reason the default produced is analyzed and a new latest available unscheduled channel with smallest void algorithm is presented. The performance of the two algorithms is simulated. The results show that in LAUC-SV algorithm the effective window of the packet loss versus unit delay time of fiber delay lines is expanded significantly and the packet loss ratio is decreased about 100.5. The algorithm complexity of the LAUC-SV is only increased arithmetically with LAUC. Both the algorithms can not support delay reservation protocol effectively.

Moreover, compared with 1 mmol/L and 3 mmol/L, 5 mmol/L treatment more significantly slowed down the maturation and consenescence process of muskmelon. Meanwhile, compared to the calcium nitrate treated for 4 h and 8 h, the discs treated for 12 h were more apparently promoted or inhibited based on above maturation and consenescence physiological parameters; however, with the prolonging of treated time to 24 h, the activities of POD, SOD and CAT dropped markedly, as well as the inhibition of synthesis of soluble protein, and the increased speed of electrical conductivity and LOX activity were reduced markedly.

据估算，与2001年相比，2002年亚太地区石油制品需求的增长值为215千桶/天，其中中国的需求增长量占总增长量的65%(与上年相比，中国在2002年的增长值为140千桶/天)。

Compared with the graphite, the coefficients of friction of the RL-C/C are lower under the same load of about 0.08-0.12, and the increasing range of the volume losses are still lower than those of the graphite. Compared with the SL pyrocarbon material, the COF and the volume loss of the SL-C/C are about 0.02-0.05 and 0.2 mm^3, lower than those under the same load. The COFs of most RL-C/C and SL-C/C specimens remain stable or decrease slightly with time, while those of the graphite and pyrocarbon specimens increase. The thickness of the integrated friction film of the RL-C/C decreases with load, but the wear surface of the SL-C/C is rough. Tough the wear surface of the graphite is integrated, the serious abrasive wear make the debris move easily and accumulate on the edge of the wear trace to form a restacked morphology. On the wear surface of the pyrocarbon material, some loosed debris, circular worn holes and flake worn out pyrocarbon has been found.
