the performances of UO_2 microspheres are as follows:density:>98%T. D. ,O/U:2.000±0.005,sphericity(D_(max)/D_(min)):1.03,crushing strenth:2 kg,closed pore size.
During crushing of carbides, if stainless steel ball milling cylinder and hard alloy balls are used and milling time is over 48h, the increments are as follows: Fe>0.1%, Co>0.2%, Ni>0.1%.
D-hydantoinase was separated and purified from Burkholderic cepecia 1003 following the steps of the crude separation(the cellular fragmentation 、the precipitation of (NH_4)_2SO_4), the purification of chromatography(Phenyl CL-4B HIC、DEAE Sepharose Fast Flow negative IEX) in this experiment. The purification multiple was 25.11 and the recycle yield of enzymatic activity was 11.87%.
本实验将Burkholderic cepecia 1003 菌株发酵产菌经过粗分离(细胞破碎、(NH_4)_2SO_4沉淀)、层析纯化(Phenyl CL-4B疏水层析、DEAE Sepharose Fast Flow阴离子交换层析)等步骤后得到纯化好的D-海因酶,其纯化倍数为25.11,酶活回收率为11.87%。
(2) patch number, patch perimeter, total landscape fragmentation index FN1 , and two shape indexes ( S1 and S2 ) are sensitive pattern indices to resolution, but patch area proportion, diversity, dominance, and element fragmentation index FN2 are weakly sensitive pattern indices to resolution;
Results:Sleep disorder were seen in 48 (96%) PD patients; these were:excessive day time sleepiness in 72.9%,insomnia in 62.5%,nightmares in 58.3%,sleep fragmentation in 58.3%,waking early in 50.0% and hallucination in 18.8%of PD patients.
We getted the optimized culture condition (Difco yeast extract 1%,glucose 1%,32℃,stilling culture)by using the orthogonal design,its mycelium production was 51 7±4 8(g/L)and the rate of cell broken was higher than 80%.
Results: Broken forces ofchewing peanuts and biscuits were respectively 47.25N (4.82Kg) and 29.12N(2.97Kg), and swallowing forces wererespectively 51.91N(5.19Kg) and 49.88N(5.09Kg), there were no significant statistical differences.
The bench tests has confirmed the operating performance of dibber, which showed that the rate of single seed was 93.3%, the rate of many seeds was 4%, the rate of hole was 2.7%, the rate of broken seed 0%.
when mycelium is broken, become inspissations, cop recitation drying , the production rate of the curious uersicolor polysaccharopeptide would achieve to 2.21g/L, polysaccharopeptide is 54.78%, tide is 32.95%.
The results indicate that the bigger deformation quantity,the worse eutectic carbide network broken,and the better impact fatigue property is ,when the deformation quantity is in 10%~40%.
A particular complex static system, viz., a partial positive feedback static system (closed cycle) for crushing mineral ores and other materials, is studied.
The problem of the nonequilibrium flow of a two-phase gas-polydisperse condensate drop mixture is considered in a one-dimensional approximation taking account of coagulation and crushing of particles of different size during collisions.
A closed system of equations in the flow characteristics is obtained in application to the general case of arbitrary size, velocity, and temperature distributions of the secondary drops formed during crushing.
Such deposits are represented by biogenic buildups (possibly, biostromes), fan limestones, synsedimentary crushing (clastic) limestones, and interbiostrome deposits (pelitomorphic limestones).
The asymmetry of the rotor caused by broken-bar fault will give rise to the appearance of additional frequency component of 2sfs (s is slip and fs is supply frequency) in the electromagnetic torque spectrum.
Then, using the instantaneous frequency extraction principle of the Hilbert Transform, the rotor broken-bar fault characteristic frequency of 2sfs can be exactly extracted from the IMF component, which includes the rotor fault information.
