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 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 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.
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 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 structure-activity relationship studies showed that the quinazoline and oxo functionalities were essential for activity.
The study showed that the introduction of a pyrazole ring on pyridazinone led to a marked decrease in AR inhibitory potency.
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.
