Cold crystal cardiac protective solution was intermittently perfused in 7 cases, with automatic heart resuscitating in 5(71 4%) and defibrillating in 2. Warm blood for cardiac protection was given in 6 cases, with automatic heart resuscitation in 5(83 3%).
1. Physicochemical properties of CPC/BMP compositeUnder scanning electron microscope(SEM) the CPC/BMP composite was found to consist primarily of platy crystals, granular crystals and some small rod-like crystals with micropores about 5-50 urn in size.
Ultrastructure of the right atrial myeeardium showed severe damage in the crystal cardioplegia group,while gfor protection in the blood cardioplegia group with higher rate of spontaneous resuming of heart beat (60.5%) vs. crystal cardioplegia group (44.9%).
Using the path model and the theory of crystals, we generalize the concept of patterns to arbitrary complex semi-simple algebraic groups.
As a result, the boundaries between the surface crystals become a little larger with prolonging the period of ageing time.
With increasing the amount of salt, there was hardly influence on the growth rate along c-axis, whereas an obvious decline was observed in the growth rate along either a-axis or b-axis, which enlarges the boundaries between the surface crystals.
The use of a temperature as high as 473 K produces a membrane composed of bar-like crystals with larger boundaries.
XRD pattern and SEM micrograph showed a good dispersion of ammonium carnallite and anhydrous magnesium chloride crystals with well-distributed big grains, just enough to meet the need for the production of magnesium metal in the electrolysis process.
The standard entropy, the surface energy and the crystal energy of ionic liquid were calculated, respectively.
The crystal energy of ionic liquid is much lower than ionic solid and this is the underlying reason for forming ionic liquid at room temperature.
The contents of the harmful chemical elements Cd and Pb were obviously reduced, while the crystal size increased from 24.5 to 35.7 nm and surface loosened.
The crystal degree of the n-HA in the composite is low and the crystal size is very small, which is similar to that of natural bone.
The study showed that the water molecules between the HAP faces were under conditions of strong electrical field and high pressure, and hence formed 2-3 well-organized water layers on the crystal surfaces.
