Results:the 6 first choice antibiotics,the changing ratio in 5 days and its effective rates: the changing ratio in 5 days and its effective rates of Ceftriaxone/Sulbactam were 74% and 68%,respectively; the Ceftriaxone were 50% and 50%,the Cefotaxime were 69% and 69%,the Ceftazidime were 60% and 60%,the Cefodizime were 11% and 100%,the Piperacillin/Tazobactamrate were 50% and 25%.

Results: In terms of course of disease, curative effect after 3 days' treatment, and rotavirus negative changing ratio, there were statistical significance between test group infants (group D) and infants of control groups (group A, B, and C) (P<0.01 or P<0.05).

During once loading,the electrical resistance of CFRC mixed with 0.18% to 0.5% carbon fiber possesses 17% to 35% linear reduction with the higher changing ratio in the vadose zone than in the over-vadose zone.

The reason for the structural characteristics indicated apparently lies in the changing ratio of the number of oxygen atoms to the numbers of atoms of the oxidizing element at the reaction front as the latter advances.

An A/V value (surface area of interior decoration materials attached to container/inside volume of container) of 2.86m-1 or various other A/V values and panel thicknesses had no significant effect on the room temperature changing ratio.

An A/V ratio (surface area/volume) of 2.86 (m-1) or various other values and the panel thickness had no significant effect on the room temperature changing ratio.

Although the ratio of differentiation into the erythroid and granuloid cell lines is kept constant in the model, a changing ratio of CFU-E and CFU-C results.

This changing ratio underscores the point that blood levels alone are not an adequate estimate of intoxication.

The laser-inducea fluorescence (LIF) spectrum of Q-branch of C1∏u(v'=0, J'= 105)- X1∑g+(v"=1-10, J" = 105) for dimer 39K2 excited by 4415.6 A CW He-Cd laser was reported. The vibrational constants of X 1∑g+ and the Te value of C1∏u for 39K2 were obtained by last-square fitting. The spectrum analysis showed that the Te= 22968cm-1 of C1∏u for 39K2 was suitable. The Franck-Condon factors of the (v' = 0, J' = 105) - (v" = 1-10, J" = 105) transitions for dimer 39K2 were computed by using Morse potentials. The agreement...

The agreement between the computed intensities and the experimental ones was satisfactory. The analysis of γ-centroid approximation showed that the. changing ratio of the electronic dipole transition moment Re for dimer 39K2 was 0.157 -0.168debye/A(4.22A<γ<4.73A).

ABS resin is an engineering plastics of having little all strinkage and good electrical and mechanical properties. Its surface is glossy. This plastics is hard and tough as well as good properties of processing. It can be processed into shapes by using injection, extruding, moulding and blowing working method etc., which are used in ordinary plastics of hot plasticity. This writting intruduces the processing principles of ABS/PMMA and ABS/HIPS composite multilays sheets oa the production line imported from Italy in Huangshi No.1 Plastics Factory. It describes the salient features of co-extrusion technology and the equipment. The writting discusses every fact effecting on the sheets quality, and the methods how to deal with the problems. The tensile yield stress of the made sheet is 44 MPa, the impact strength 207 MPa, the hot deformation 90℃, the demension changing ratio -4.7, ball indentation hardness 69.4N/mm~2. All these technical specifications reach to GB10009-88, the Standard in the P. R, C.

The LIF (laser induced fluorescence) spectrum from C~1Пμ→ X~I∑_8~+ of ~(39)K_2 dimer excited by 4415.6A H_e-C_d~+ CW laser line is reported. The sample of ~(39)K_2 was produced in heat pipe oven with buffer gas Ar. The LIF spectrum was measured by use of GDR-1000 modal double gratings monochromater. The intensity of spectrum was calibrated by tungsten standard lamp. The analysis of spectrum pointed out that LIF spectrum came from the R and P branches of C~IП_μ (v' = 0, J' = 53)→ X~1∑_g~+ (v" = 0 -11, J" = 52,...

The rovibration constants of X~∑ + and Te value of C~1П_μ was fitted out by least-squares method. with the for- g mula of the emission spectrum I∝ v'R_cq_(v'v") the spectrum intensities of (v' = 0, J' = 53) - (v" = 0-11, J" = 52, 54) transitions of ~(39)K_2 was computed by use of RKR potentials. The agreement between the computed values and the experimen- tal one was satisfactory. Further analysis of r-centroid approximation showed that the changing ratio of the dipole transition moment R_e (r) of C~JП_μ→X~I∑_g~+ of ~(39)K_2 dimer with internuclear distancer could be deduced by formula (I_(exp)_(V'V")) / (I_(cal)_(v'v"))∝(R_e(r_(v'v"))) / R_0 = 1 + α / R_0 r_(v'v") where r_(v'v") = < v'|v" > / < v'|r|v" > was r-centroid computed. The result by use of least-squares fitting was |α / R_0| = -0.157 debye / A in 4.22A < r < 4.71 A.
