The results show that the light steel-framed with web perforation can decrease the heat transfer coefficient of the composite wall The parameters of this steel structure is as follows: 4～6 rows of slots are recommended,the length of slots is 70～80 mm,the width of slots 2～3 mm,the distance between them in the transverse direction 6~9 mm and in the longitudinal direction is 20～30 mm.
The results show that the optimal usage of cement is 467kg/m3,and the 90-day's compressive strength is 88% of concrete,which cast in air. The dimension of steel tube has prominent influence on experimental result.
Test results show that gradation 1 and gradation 4,gradation 2 and gradation 3 have the similar performance of frost resistance; the frost resistance coefficient of the former is about 40% when the cycle of freezing and thawing is 50 and the coefficient of the latter is still larger than 70% when the cycle is 100.Besides,the former is much smaller than the latter and the frost resistance coefficient decreases with the increase of cycle of freezing and thawing.
The main influencing factors on the CCMP conversion ratio are examined. The experimental results show that under 700 r/min stirring rate,reflux temperature 92 ℃,V(OH-)/V(CCMP)=5∶1,10%(wt) of alkali solution concentration,DMF 15%~ 30%(wt) against to CCMP,20%~25%(wt) better,the reaction time 6 h,the conversion ratio of CCMP can reach over 95%.
Dairy cow were inseminated with routine semen and sexing semen separated by flow cytometry in this experiment and the results showed that the pregnant rates of the treatment group (sexing semen) and the control group (routine semen) were 54.81%(74/135) and 60.61% (40/66) respectively,and there was no significant difference between them (P＞0.05).
The results showed that panicle quantity types,which was 80% of the plan,main used the 0、0-2、0-3、0-4、0-3-1 tillers. When it was 100% of the plan,it main used 0、0-2、0-3、0-4、0-5、0-2-1 tillers.
The results showed that: the 22.5 cm ridge distance,370 000 plants per hm2,the 45 cm ridge distance,400 000 plants per hm2 were the best cultivation patterns for Fengshou No. 24.
The result shows that the pear leaves,dealt with 1.0 mg·L-1 of sodium selenite,could restrict the reduction of activities of APX,GPX,GR and SOD after the leaves were infected with Physalospor Piricola Nose.
The blackbody radiation experiment shows that the TiO2/SiO2 nanonlultilayers have good infrared absorption within the wavelength range of 800nm～1400nm, and the absorption coefficient increases as the temperature rises.
The tested result of XRD shows that under the same diffraction conditions,the 2θ of cubic ZnMgO is smaller than that of cubic MgO when 6 coordinated Mg2+ is substituted with ones of Zn2+.
The calculated results indicate that the random wave response of the wave-permeable breakwater can be effectively controlled when proper TLD parameters are selected.
The results indicate that the absorption of the brine pockets in the sea ice (mainly in the short wave of 400 – 500 nm ), and that of the pure ice ( mainly in the long wave of 700 - 900 nm ), as well as the scatter of brine pockets and air bubbles have great effect on the light attenuation coefficient of the sea ice.
The results indicate that the mechanical properties are better than those of quenched and tempered steel 40Cr,and the machinability is much better than that of 45 steel.
Experiment results indicate that on average 62.6% memory bandwidth in STREAM benchmarks is improved by utilizing the cache adaptive write allocate policy. The performance of SPEC CPU 2000 benchmarks is also improved efficiently. The average IPC speedup is 5.9%.
The compared experiment results indicate that the improved method increases the stability of turbulence-degraded image restoration,and reduce the influence of random noise on image restoration.
We introduce the (purely algebraic) notion of ann-Hopf algebra and show that the ring of functions on ann-valued group and, in the topological case, the cohomology has ann-Hopf algebra structure.
The activity profiles of the intracellular and extracellular crude extracts showed that the antibiotic producing culture produces two or more compounds, one being intracellular (antifungal), other being extracellular (antibacterial).
The results showed that these compounds are capable of important interactions with the NNRT binding site, which encouraged us to submit them for biological assay.
Results showed that over the concentration range of 6-16 mM, Me2SnCl2 is a chemical denaturant and denatures the double-strand DNA in a three-state manner.
For example, our result shows that a "slight" random perturbation of the classical Cantor set becomes a "nice" set in the sense that its Fourier dimension equals its Hausdorff dimension.
The proof is based on the Heil and Walnut's representation of the frame operator and shows that it can be decomposed into a continuous family of infinite matrices.
The study shows that government has made some important changes after the signing of WTO agreement in 1994, but there are still some contentious issues that require attention.
