黑云母带的变质条件估计在445～550℃、压力在0.2～0.6GPa范围变化；石榴石带温度在480～566℃、压力在0.54±0.22GPa的范围；十字石带范围为601±20℃、0.8±0.25GPa；十字石-红柱石带为540±20℃、0.32±0.05GPa，而利632.4℃、0.785GPa，这个值不是红柱石的稳定范围，这可能是其早期中压变质条件；矽线石带的条件640℃、0.43GPa左右，由于其石榴石中有蓝晶石包体，因此其早期也可能有中压条件的变质；堇青石-夕线石带范围大致为740～800℃、0.4～0.7GPa之间。

SPSS11.5 and excel statistical software were performed for the statistical analysis. 2. Experiment in vivo MRIgHIFU thermocoagulation was carried out in muscular tissues of rabbits. The parameters were power-250W and time-15s under the dot irradiating. MRI T-MAP was observed during treatment and the region size of adscendent temperature was measured (blue:45℃-50℃,green:50℃-55℃,yellow:55℃-60℃,red:60℃-100℃).Af-ter treatment, firstly, scan PD_tse and T2_tse, secondly, observe the changed signals of these images and measure the regions, finally, observe skin damage and measure the tissue necrosis.

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

However,when increasing x_(12) in the range of larger than 1,the change tendency of the binodal curve position is also affected by the values of x_(13) and x_(23).(3) The ternary phase diagrams of ScCO_2/acetone/CA,ScCO_2/toluene/PSt and ScCO_2/solvent/PVB systems are calculated using the thermodynamic model.

当x_(12)在小于1的范围内变化时，随着x_(12)的增大，均相区增大；然而当x_(12)的数值跨越了该分界点在大于1的范围内变化时，随着x_(12)的增大，双节线位置的改变将受到x_(13)、x_(23)具体数值的影响，从而不再沿单一方向迁移。

The code MFEL 1 is applied for short pulse case of, for example, rf linac FELs, FELO is for single mode simulation which can describe the motion in phase space of electrons with energy spread and give some interesting results in short computer running time.
