Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.

惠州西湖的游植物密度平均为5958.63×10~4Cells／L，约为杭州西湖的1／3左右，没有明显的水华发生，这可能是由于西湖鱼类和游船引起的悬浮物浓度较高，使光照强度降低，从而抑制浮游植物的生长。

The phenomena of improved confinement has been observed with ECRH auxiliary heating under limiter discharge condition on the HL-2A tokamak, and electron line average density, plasma stored energy, radiated power within the separatrix, energy confinement time, H-alpha line emission etc, have been studied for the transition from L-mode to improved mode.

In the case of granite, observation results indicate that the extending routes of active cracks are mainly intercrystalline, transcrystalline, inter-transcrystalline, and intracrystalline. When the strain rate is low, the long intercrystalline cracks are prevailing, and with increasing of the strain rate, the short transcrystalline and intracrystalline cracks gradually increase. The statistic results show that the active crack density increases with increasing of the strain rate, and the mean length of active cracks diminishes with increasing of the strain rate, that is, the induced damage in comminuted product increases with increasing of the strain rate. For the first time this dissertation integrates macroscopic results of comminution with active crack growth under impact loading. It elucidates why the dynamic comminution strength of mineral beds increases with increasing of the strain rate through the active crack extending, and analyzes the influence of structure and constitution of minerals on their damage under impact stress. It is authenticated that both the size distribution and the damage population of comminuted product can be characterized by the fractal.

为分析料层颗粒在冲击下的细观损伤效果，采用德国生产的ASM68K半自动图象分析仪对粉碎生成物中的损伤情形进行了观测，以花岗岩为例，观测结果表明花岗岩颗粒在冲击应力下的活化裂纹扩展路径主要表现为沿晶、穿晶、沿穿晶和晶内等形式，在低应变速率下，活化裂纹以沿晶裂纹较多，随着应变速率的提高，其它裂纹形式大量繁衍，统计结果表明活化裂纹密度随着应变速率的增大而增大，活化裂纹的平均长度随着应变速率的增大而减小，综合表现为颗粒的细观损伤程度随着应变速率的增大而增大；首次将应力作用下的活化裂纹演化特征与粉碎的宏观效果相联系，并就料层动态粉碎强度随应变速率增大而提高的现象从裂纹演化特征的角度进行了解释；分析了矿岩构造结构特性对损伤产生和分布的影响。

Estimated value of the strain is 4.87×10^(-3). The energy stored in shocked powders was released during sintering process.
