When the explant size with epidermis was 0.5cm×0.3cm× 0.2cm, more loose callus could be induced from the Guangzhou white peel garlic in the medium of MS+ 3.0mg/L 2,4-D + 1.2mg/L 6-BA under condition of 600 lux 12 hours circular illumination.
During the orthogonal experiments of the culture media,2,4-D and 6-BA inductive callus tissues,it is discovered that the better culture media combination for the inductive callus tissues is MS+2,4-D 1 mg/ L+6-BA 0.4 mg/ L,and that the produced callus tissues are mostly greenish,loose in texture,fast in growth,prolonged in browning and suited for the induction of androsace callus tissues.
① The mean CBF, and the regional CBF of frontal, temporal and parietal lobe cortexes and loose area of cerebral white matter in the silent Leukoaraiosis group were all obviously decreased as compared with those in the control group (369.1±41.6), (394.2±36.5) mL/g per minute, t=2.30,P < 0.05;
The suitable site for planting is that of open ground, full of sunshine, loose soil, epipedon organic matter more than 2 %, total nitrogen more than 0.1 %, available phosphate more than 0.25mg/100g soil, pH value 4.5-6.9, and the soil moisture content is 10 %~24 %.
The white limestone saprolite of a limestone weathering section in Kunming has a porous macro structure and its density,porosity and intrinsic permeability are 1.8081 g/cm3,32.65% and 774.8139×10-3 μm2 respectively. The corresponding parameters of the fresh limestone are 2.6966 g/cm3,0.05% and 0.0084×10-3 μm2 respectively.
The cleanness of the steel has been improved by these methods and we have the content of elements in the steel as following , [H]≤2.5×10-6, [O] ≤20×10-6, degrees of the bloom's porosity and segregation are less then 1.0 grads.
The Effect of Sodium Modifier on the Shape and Distribution of Porosity about Cast Alloy ZL104
It was obtained by statistic analysis on examination results of Φ40 mm rolled products of 111 heats that the porosity rating of product was no more than 1.5, segregation rating 0.5, hardenability J9(HRC) 30～40 and J15(HRC) 22～35 to meet the standard requirement.
after pouring steel,the weight of the resulting billet with loosen degree under 1.0 in the central accounts for 0.4%,while the weight of the billet with loosen degree from 1.0 to 2.0 in the central is only(0.12%.)
The carbon-abundant area is the zone where graphite and organic fibre are comparatively gathered, while the spalling area is the zone where the surface film is spalled and its surface is rough and uneven, with a loose and denuded state.
The observation by using scanning electronic microscopes showed the cake layer with loose structure and large thickness formed on the membrane surface due to the appearance of filamentous bacteria and high SVI in sludge.
Proteins from flour with short-tearing gluten, including the water-soluble and salt-soluble fraction, had a loose spatial structure.
Meanwhile inactive multiple bands emerged and became thicker, which implied that lactate dehydrogenase became loose.
It was found that the modifying layers of the sorbents are getting loose under the effect of adsorbed water, and water molecules gain access to the sterically screened OH groups; the heat of water interaction with these groups is 54-55 kJ/mol.
Although the classical Fractional Brownian Motion is often used to describe porosity,
The porosity and percentage of tiny sand (diameter 0.05-0.1 mm) and clay particle (diameter >amp;lt; 0.05 mm) increased, bulk density in surface soil decreased, and saturated water-holding capacity improved.
The process easily controls the porosity, the pore size, the pore orientation, and the pore morphology when the melting and solidifying conditions are varied in a wide range.
Experimental studies on the influence of porosity on membrane absorption process
However, the influence of porosity on the membrane absorption process became visible for fast mass transfer system.
The variation of the activation energy is associated with the ability of the metal surface to form strong chemisorptive bonds with valence-active edges of graphite islands, which loosen C-C bonds in graphite.
These granules in colored alpaca fibers loosen the bundle of cortical cells, providing many crannies in the fibers which may contribute to the superior flexibility, warmth and softness of the fibers.
Tobacco samples were treated with a small quantity of aqueous ammonia solution, to loosen the tobacco tissue and to convert all alkaloids to free bases, then extracted with 1:3 CH3OH-CH2Cl2.
