By adding some roll scale and controlling the reaction time within 5～8minutes, the content of ΣFeO, MgO in the slag could be maintained in the range near the initial value so that the reaction process simulated the actual process more stably.
According to the analysis in this paper,were it not for these artificial factors,the two of the flood peak discharge,on Aug 4,1996 and on Aug.5,1993 would have been very near,however,by measurement,one was 4100m3/s (1996),the other one was 2800m3/s(1993),made at Quankou hydrometric station.
A very near relation between the two salt-tolerant populations of Atlantic and Weinan was observed in our study, whose genetic resemble coefficient was 0.9077 by the 0/1 method, and 0.9592 by the tetraploid method.
The results of blast and phyligenetic tree analysis showed that the HA gene of A/Equine/Qinghai/1/94/was very near to A/Equine/HongKong/1/92.This date indicates that the epidemic of equine influenza in Qinghai province in 1994 has a close relationship with the avian influenza outbreak in HongKong in 1992.
The observed helium content data in Liaogu 1 well from 1981 to 1984 have been processed. It has been found that the data of helium content have a clear abnormal change and their anomaly forms are very alike before two near earthquakes (Ningjin M S5.8 in 1981 and Heze M S5.9 in 1983).
The Sr-Nd isotopic data pose the characteristics of high(~(87)Sr/~(86)Sr)_0(0.70625～0.70912)and lowε_(Nd)(-5.22～-3.68),and lie between EM1 and EM2 end members,especially near EM2.All these characteristics show that the lamprophyres were derived from a metasomatized enriched mantle source region.
Results 90.38% (47/52)of the eyes with MIOL achieved a uncorrected near acuity of 0.4 or better,which was better than with SIOL(21.74%,10/46)(χ~2=53.174,P<0.01,the difference was statistically significant);
