机器翻译质量综合评价方法研究

基于对“词汇”、“语法”和“语篇”三个译文质量评价因素的分析，本文构建了包含12个指标、每个指标分为5个质量等级的评价指标体系，通过问卷设计与问卷调查方法获取机器翻译质量的评价数据。采用层次分析法确定评价指标的权重向量，利用模糊数学理论建立了机器翻译质量的综合评价向量模型。实例分析表明，该模型可以科学定量地评价翻译软件的译文质量及其在各项评价指标上的差异，对读者筛选优质翻译软件、开发商提高软件质量具有重要意义。Based on an analysis of three factors in the assessment of translation quality, i.e. vocabulary, gram- mar and discourse, this paper developes an evaluation index system which includes twelve indicators and each indicator is divided into five levels. Meanwhile, a questionnaire is also designed for use. Foreign language teachers and Master＇s degree candidates are selected as respondents. Then, the data for machine translation e- valuation is obtained from the questionnaire. The analytic hierarchy process （AHP） is applied to the data in or- der to determine the weighted vector of machine translation evaluation factors. On this basis, fuzzy mathematics theory is used to establish the comprehensive evaluation vector for machine translation quality. As a result, the quantity comprehensive evaluation for the translation text quality is completed. The results of our study show that the comprehensive evaluation model of translation quality based on the AHP and fuzzy mathematics method can be employed to scientifically and quantitatively analyze the translation text quality of the translation software as well as the differences of various evaluation indicators. Thus, this is significant for readers to choose high quality translation software and for software developers to find design flaws so as to improve the software design and the quality of software.本文是2016-2019年度西班牙国家科学研究项目“东亚研究”（项目编号：FF12015-70513-P）的阶段性研究成果之一.在研究过程中获得该项目的资助

Feasibility Evaluation of the Statistical Delay Quality Model (SDQM)

遅延テストの品質評価には，遷移遅延故障モデルが広く用いられてきた．しかし，論理的な網羅性のみに着目しているため，微小な遅延欠陥の検出能力は明らかでなかった．そこで筆者らは微小な遅延欠陥の検出能力を，半導体製造プロセスの品質，設計の遅延変動に対するロバスト性，テストタイミング精度，及びテストパターンの論理的網羅性を総合的に反映して求める統計的遅延品質モデル（SDQM：statistical delay quality model）を提案し，本論文では，その大規模データに対するフィージビリティを評価した．商用のテスト生成ツールによるテストパターンを用いてSDQM の計算を行い，SDQMの計算の処理時間とメモリ量が適用可能なレベルであることを確認した．また，本モデルを用いたテストパターンの分析により，従来の遷移遅延故障モデルによるテストパターンは，長い論理パスが活性化されて初めて可能になる微小遅延欠陥の検出能力が十分でなく，アルゴリズム改良が必要なことを，定量的に示すことができた

[ Methods ] The lentiviral expression vector for EGFP - hFcRn fusion protein was constructed. Generating by co - transfection of four -plasmids into HEK 293T cells ,the lentivirus particles were used to infect MDCK cell line. EGFP positive single cell was obtained by FACS, and then FcRn expression was identified by fluorescence co -location with EGFP - β2m and confirmed by Western Blot. Flow cytometry was used to detect binding activity of hFcRn and human IgG. [ Results ] DNA se- quencing demonstrated that the lentivirus vector pEGFP - FcRn was constructed successfully. The percentage of EGFP - posi- tive ceils was about 26.5% after infection. Expression of the complete protein was detected through fluorescence co - location and Western Blot, respectively. Flow cytometry analysis showed that the cell lines could pH - dependently capture human IgG. [ Conclusion] MDCK cell line stably expressing functional visualable hFcRn was established.基金项目：国家自然科学基金项目（“结构生物学指导的HBV治疗性抗体人源化及其关键技术研究”,No.31600748;“抗呼吸道合胞病毒高中和活性抗体的保护机制研究”,No.81401668;“基于广谱中和单抗的通用型流感疫苗设计及其结构基础研究”,No.31670934

Precise Measurement of Cosmic-Ray Proton and Helium Spectra with the BESS Spectrometer

We report cosmic-ray proton and helium spectra in energy ranges of 1 to 120 GeV and 1 to 54 GeV/nucleon, respectively, measured by a balloon flight of the BESS spectrometer in 1998. The magnetic-rigidity of the cosmic-rays was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 Tesla. Those spectra were determined within overall uncertainties of +-5 % for protons and +- 10 % for helium nuclei including statistical and systematic errors.Comment: 12 pages, 4 figure

Measurements of atmospheric muon spectra at mountain altitude

We report new measurements of the atmospheric muons at mountain altitude. The measurement was carried out with the BESS detector at the top of Mt. Norikura, Japan. The altitude is 2,770 m above sea level. Comparing our results and predictions given by some interaction models, a further appropriate model has been investigated. These studies would improve accuracy of atmospheric neutrino calculations.Comment: Mean momentum in Table 1 was correcte

Measurements of Cosmic-ray Low-energy Antiproton and Proton Spectra in a Transient Period of the Solar Field Reversal

The energy spectra of cosmic-ray low-energy antiprotons and protons have been measured by BESS in 1999 and 2000, during a period covering the solar magnetic field reversal. Based on these measurements, a sudden increase of the antiproton to proton flux ratio following the solar magnetic field reversal was observed, and it generally agrees with a drift model of the solar modulation.Comment: 4 pages, 4 figures, revised version accepted for publication in Phys.
