In addition, the ingredients have been tested by the IR spectra which show the probability of the nano-porous structure. SEM pictures, specific surface areas and distribution of pore diameter have been tested to study the nano-porous structures in surface and some data before and after the pyrolyzing process have been gained: the size of the organic aerogel is 30~50nm, that of the carbon aerogel is about 10nm, the specific surface area increases from 341.77m^2/g to 452.75m^2/g, the density increases from 0.1708g/cm^3 to 0.3356g/cm^3 respectively.

借助有机气凝胶的红外光谱研究了其化学结构，说明其网孔结构形成的可能性；研究了有机气凝胶的扫描电镜图像、比表面积及孔径分布等，并得到碳化前后的一些对比数据：有机气凝胶颗粒大小30~50nm，碳化后约为10nm，比表面积从341.77平方公尺/g增大到452.75平方公尺/g，密度从0.1708g/立方公分增大到0.3356g/立方公分。

After the animal modle done successfully, all animals were randomly divided into two groups. group l: Microbubble contrast agent containing plasmid was injected into nude mice via the tail vein; group 2: the mixture of microbubbles with plasmid was injected as the group 1, and eyeballs were exposed to ultrasound with intensity of 0.5W/cm^2 immediately, and the time were all 60s that working time control at 20%.

将12只BAlB/C裸小鼠双眼玻璃体腔接种HXO-Rb44细胞，造模成功后，将动物随机分为2组，第1组于尾静脉注入含质粒的微泡造影剂；第2组尾静脉注射质粒与微泡的混合液，并立即以0.5W/平方公分〔1〕的超声波辐照小鼠眼球60s，工作时间控制为20%。

Methods At different timepoints after microwave exposure of 65mW/cm^2 for 20mm, learning and memory ability was evaluated with shuttle box test and Morris' water maze test, long-term potentiation was detected in hippocampal slices in rats.

采用功率密度为65mW/平方公分的微波全身一次辐照大鼠20min，在辐照后不同时相点观察大鼠学习记忆行为的改变（穿梭箱试验和Morris水迷宫试验）和海马离体脑片LTP的诱导变化。

The irradiation effects of C60 films induced by 0.98GeV Fe ions at the same electronic energy loss of 3.5keV/nm and different irradiation dose ranging from 5×10^10 to 8×10^13 ions/cm^2,were analyzed by Raman scattering and Fourier transform infrared spectroscopes.

利用傅立叶转换红外光谱和Raman谱仪分析了0.98 GeV的Fe离子在电子能损S为3.5keV/nm时，不同辐照剂量(5×10^10-8×10^13 ions/平方公分)下，在C60薄膜中引起的辐照损伤效应。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
