Zinc injection to the primary circuit of pressure water reactor is an effective technique to mitigate stress corrosion cracking and reduce radiation field. It is known that the oxide film of stainless steel formed with chromium oxides and iron-nickel oxides shows a semiconductor behavior, and cave in the semiconductor is occupied by zinc instead of cobalt. This paper studies the semiconductor character of film formed on Type 3.4L stainless steel in high temperature water (HTW) containing zinc ions by electrochemistry method. Oxide films of 3.4L stainless steel is formed in HTW contained 1mM ZnSO4. All tests are carried out in boron buffered solution (pH8.4) at room temperature. Dynamic scan and Mott-Schottky scan are performed with 2.73.potentiostat of Princeton. In the photocurrent test, light from xenon lamp goes through the monochromator and irradiates onto the working electrode. Monochromatic lights turn on intermittently to check the photocurrent response. Bias potential is applied on the work electrode and stepped from the top of passivation zone of polarization curve to the corrosion potential. Photocurrent response is recorded with pen recorder. SEM is used to inspect the surface of samples. The polarization curve results indicate that the passive film formed in zinc contained HTW has stronger corrosion resistance. With zinc treatment, Mott-Schottky plot shows the flat band moves to lower potential and the donor density which are calculated from Mott-Schottky data decreases. Photocurrent response shows the oxide file formed on stainless steel in HTW with zinc is the bilayer structures and shows an n-type semiconductor character, contrast to the film which formed on stainless steel in HTW without zinc and show the p-type semiconductor character. Band gaps of the passive film are also calculated from the photocurrent results. SEM pictures indicate that the oxides on the film in zinc contained HTW is less than the ones in non-zinc environment.

针对雅安大相岭以南为亚热带湿润偏干季风气候区(汉源、石棉),以北为亚热带湿润季风气候区的气候特点,将雅安分为南部和北部两个亚区,从气候、土壤、灌溉、地形条件入手选择评价指标,并以不同灌溉条件的选择和海拔分级体现南北差异。采用层次分析法确定各评价因素权重,用指数和法计算各评价单元的综合分值,最后采用均匀内插法,进行分等定级。评价结果表明,雅安市耕地后备资源以三等和五等居多,其土壤类型以暗棕壤、沙黄泥土、淋溶紫色土、砖红紫色土为主。针对耕地后备资源特点,建议对耕地后备资源开发利用时,应根据后备资源质量等级及其限制条件,采用不同的开发手段;对有较严重限制因素的耕地后备资源,宜暂缓开发。

答案选择的主要任务是对问答系统中问题的候选答案排序,当前主流的方法是基于表示学习方法,通过神经网络对问题和答案进行向量表示,然后根据向量相似度对候选答案排序,该类方法忽略了问题和答案的局部关联性。针对这一问题,提出了一种基于多尺度相似度特征的深度学习模型。该模型采取传统的深度学习模型分别提取问题和答案的特征,然后计算各个尺度下的特征相似度得到问答的相似度矩阵,最后采取三种不同的相似度特征学习模型对相似度矩阵学习得到联合相似度。在公开数据集WebQA上进行实验验证,实验结果表明将相似度特征学习方法引入传统深度学习模型获得了较为明显的提升。

Based on the Dyson-Schwinger Equations with "rainbow" approximation, the fully dressed confining quark propagator is investigated, and then the mass functions A(q) and B(q) are obtained in the approximation. Using the resulting A(q) and B (q),the pion decay constant fis predicted. A comparison of the predicted fwith it’s value of experimental measurement is also performed. A great agreement is obtained. With the predicted fand values of Goldstone Boson masses measured by experiments the current masses of light quarks and in-medium Goldstone bosons are obtained.

This paper mainly discusses the timing of the Karakorum strike-slip fault, and gives a brief introduction of its structures, offset, and deformational style. This fault strikes NNW-SSE. Asymmetrical folds, stretching lineation, S-C fabrics, feldspar and quartz s?-porphyroclasts, domino structure, shear cleavages and faults in the fault zone are products of tectonic movements. They all indicate a dextral slip sense of faulting. Mylonitic bands are widely developed along this fault. Phengite appears, indicating rather high deformational pressure. Geochronological data indicate that the Karakorum strike-slip faulting occurred from 6.88±0.3. to 8.75±0.2. Ma. The cumulative displacement from Muztag Ata to Muji is about 13. km.

Objective To elucidate potential activities of phthalides and terpenoids from Angelica sinensis by theoretical docking calculation. Methods Eleven components of phthalides and terpenoids were selected as ligand. The crystalline structures of targets related to common diseases were used as the receptors for calculation. The calculations were conducted with Schr?dinger software package. The grading standard of selectivity was developed according to G-score between ligands and receptors. Results Selective targets of phthalides and terpenoids were related to nevous system diseases, cancer, pain, diabetes, cardiovascular disease, liver cirrhosis, nephrotic syndrome, inflammatory diseases, rheumatoid arthritis, dermatosis, leukemia, microbial inflections, immune diseases, and hypercholesterolemia. In addition to the medical treatments reported in the literature, our research also indicated that these two classes of compounds may be used for tumor, diabetes, rheumatoid arthritis, dermatosis, leukemia, liver cirrhosis, and nephrotic syndrome. According to our research, the effects of phthalides and terpenoids may be not so strong. Conclusion The effects of phthalides and terpenoids on diseases founded through virtual evaluation accord greatly with those reported in experiment and clinic. The combination of computer-aided drug evaluation technique and experiment is definitely an important and fast way to investigate the effects and mechanisms of traditional chinese medicine.
