An average output power of 1.52 kW is obtained from two disks with a diameter of 40 mm and a thickness of 1.3 mm. The pumping peak power on each disk is 17.7 kW with duty cycle of 10%. The optical efficiency of the laser system is about 43% and the electrical to optical efficiency is more than 20%.
When the frequency is 1.63～2.22 GHz,the conversion efficiency of the converter is over 90% with bandwidth over 30%,and the reflectance is less than-11 dB.The highest conversion efficiency is 99.8% and lowest reflectance is-26.3 dB when the frequency is 1.72 GHz.
Recognition rate on the national speech recognition evaluation database indicate a relative 3.5% reduction in the word error rate of Lattice-MLLR over traditional MLLR,and the proposed measures can decrease more than 87.9% in computation of Lattice-MLLR.
Compared with the composite without coupling agents,the physical and mechanical properties of the composites using PU1 and PU2 are improved significantly,while effect of PU1 is superior to PU2. With 2.5 % PU1 coupling agent,the physical and mechanical properties of the composite exceed the standard GB/T 4897.6-2003 used for heavy-duty load-bearing boards in humid conditions.
Results In comparison with the value before coronary angiography,serrum cystatin C significantly increased at 1-day after angiography(P<0.01) and exceeded normal limits,serum cystatin C still increased at 2-day after angiography(P<0.01﹚)but fell into normal limits.
②The infective rate of HBV and the carrying rate of HBsAg in the PHC group were both significantly higher than those in the non-PHC group and health check-up group (P<0.005), the relative risk(RR) both exceeded 1, and the attributable risk percentage (AR%) was all about or over 75%;
When giant panda post-thaw sperm was treated with PAF,sperm quality in 50 ng/mL group was better than that in 100 ng/mL group,but the sperm quality would obviously decrease when incubation time exceeded 2 hours.
Finally we show for more than half of the infinite series that a presentation for the fundamental group of the space of regular orbits ofW can be derived from our presentations.
Among a total of 38 glycosyl ureas, 2 showed more than 50% inhibitory effect.
Among a total of 66 glycosyl ureas/ thioureas and glycopeptidyl ureas, 3 showed more than 50% stimulatory effect whereas 2 showed more than 50% inhibitory effect.
Among a total of 59 C-nucleosides/ S-containing nucleosides, 24 showed more than 50% stimulatory effect.
However, high (denaturing) concentrations of Me2SnCl2 (more than 9 mM) caused considerable destabilization of DNA associated with the formation of a partially unfolded intermediate at 13.6 mM of Me2SnCl2.
We develop methods that give rise to natural monomial bases for such rings over their ground fields and explicitly determine precisely which monomials are zero in the ring of coinvariants.
Using these monomial bases we prove that the image of the transfer for a general linear group over a finite field is a principal ideal in the ring of invariants.
As an application we produce complete hyperbolic 5-manifolds that are nontrivial plane bundles over closed hyperbolic 3-manifolds and conformally flat 4-manifolds that are nontrivial circle bundles over closed hyperbolic 3-manifolds.
Equivalently, ifCn, is the total space for a principalGa-bundle over some open subset ofCn-1 then the bundle is trivial.
We consider varieties over an algebraically closed field k of characteristicp>amp;gt;0.
The performance indices of plywood, particleboard and medium density fiberboard (MDF), hot-pressed by nano-SiO2 (1%)/UF resin (F/U molar ratio=1.2), exceeded the requirements of the National Standard.
Thirdly, based on gray cognate analyses of factors affecting runoff and sediment production in sloping land, the factors of stand canopy density and herb and litter biomass were the most significant ones, whose gray incidence degree exceeded 0.6.
Among the 54 examined species, 26 species exceeded 80% germination, 11 species exceeded 60%-80% germination, 8 exceeded 40%-0%, 5 exceeded 20%-40%, and 4 showed less than 20%.
At 100% relative humidity, above 90°C the conductivity of the composite membrane containing 40 wt-% of Zr(PBTC) exceeded that of the Nafion?115 membrane and even reached a high value of 0.36 S·cm-1 at 160°C.
However, no nanotube could be formed or even the carbon matrix generated when the concentration of O2 or H2O exceeded a proper value in the mixture.
