RESULTS:① No obvious sight defect was detected with the quantitative detection of automatic sight apparatus.② ECT cerebrospinal fluid imaging thought that proximal frontal sinus of right cerebral frontal lobe was the leakage, and the liquid glucose in nasal cavity was quantitatively confirmed to be cerebrospinal fluid.③ Cranial CT showed that cleft could be observed in bilateral frontal lobe and lateral ventricle, low-density gas shadow could be observed in cisterna ambiens, cortex of frontal bone was discontinuous, and bone matrix was trapped.④ ECG showed that right forehead and temple had irregular slow wave, and attack of θ wave. Brain topographic mapping showed that the δ power value of right forehead was increased.⑤ EPQ: The scores of extraversion-introversion, neuroticism, psychoticism and lie were 55, 55, 80 and 50 respectively;⑥ MMPI: The code showed a mode of 69/96, indicating that the brain organ tended to paranoid schizophrenia.

The calculation of parameter m_0,that is the amount of CO_2 absorbed by unit volume of concrete completely carbonated,was proposed by the analysis of concrete hydration process and carbonation mechanism,and the simplification formula of fly ash concrete applied in practice was suggested.The calculation of another important parameter D_e,that is the effective diffusion coefficient,was also proposed on the basis of the mechanism gas diffusion in concrete.

通过对混凝土水化过程、碳化机理的深入分析，提出了模型参数——完全碳化时单位体积混凝土吸收二氧化碳的量m_0的计算方法，并给出了工程中常用粉煤灰混凝土的简化实用公式；基于气体在混凝土中扩散机理的分析，给出了另一个重要的模型参数——二氧化碳在混凝土中有效扩散系数D_e的计算公式。

The theory is that electron launched by electron gun is inducted into discharge chamber with screen voltage attracting, gas will be charged by inputting RF power. Ion can be attracted by screen and accerlate voltage.

射频宽束离子源工作原理是利用电子发生器产生电子，在屏极电压作用下把电子引入离化室，利用射频感应原理将能量耦合到离化室，再利用气体放电原理产生等离子体，在屏极和加速极的作用下引出离子束。

The toxic hydrogen selenide gas was reduced, while the utilization of sodium borohydride was over a lot when the PEG-400 instead of ethanol.

相对于乙醇、水等作为介质合成二硒醚，以PEG-400为介质减少了剧毒气体硒化氢的排放，同时硼氢化钠的利用率有所提高。
