日语「ている」形式的用法以及意义

日语中的「ている」一直是日语学习的难点之一.初学者总是将其与时态(「テンス」)这一概念相联系,但是实际上「ている」形式与体(「アスペクト」)这一语法概念更有着千丝万缕的联系.从体(「アスペクト」)这一角度出发,对「ている」形式的用法以及意义进行探讨.

基于IGBT逆变器的大功率直流稳压电源

针对目前国内用于电源的晶闸管静态逆变器,其逆变频率的范围窄,限制在8KHz以下,实际产品一般仅为1KHz左右,且当感应器改变时,不能进行频率调节等问题,通过应用IGBT逆变器设计了一款大功率的直流稳压电源,该电源以16位单片机MPS430为控制核心,组成大功率直流稳压电源的控制系统.该系统不仅具有较高的可靠性,还具有良好的工艺性能.由于使用了高频器件,整个系统具有小型化、轻量化、高效率等优点,符合现代大功率直流稳压电源的发展潮流.本文就其设计的主要思想进行了阐述.

Treatment and hydraulic performances of the NiiMi process for landscape water

This paper describes the NiiMi process designed to treat landscape water. The main aim of the research was to investigate the feasibility of NiiMi for removing organic and nutriment materials from landscape water. During the batch-scale NiiMi operation, the removal rates of color ranged from 66.7%o-80% , of turbidity from 31.7%-89.3%o, of chemical oxygen demand （COD） from 7%-36.5%, of total phosphor （TP） from 43%-84.2%, of soluble phosphate from 42.9%-100%, of total nitrogen （TN） from 4.2%-46.7%, and of NH4^＋-N from 39.3%-100% at the hydraulic loading of 0.2 m^3/（m^2·d）. Results showed that the removal efficiencies of COD, TP, soluble phosphate and TN decreased with the decline in the temperature. The NiiMi process had a strong shock loading ability for the removal of the organics, turbidity, TP, soluble phosphate, TN and NH4^＋-N. Three sodium chloride tracer studies were conducted, labeled as TS 1, TS2, and TS3, respectively. The mean hydraulic retention times （mean HRTs） were 31 h and 28 h for TSI and TS2, respectively, indicating the occurrence of a dead zone volume of 12% and 20% for TS 1 and TS2, respectively. TS 1 and TS2 displayed the occurrence of short-circuiting in the NiiMi system. The comparison results between TS1 and TS2 were further confirmed in the values obtained for some indicators, such as volumetric efficiency （e）, short-circuiting （S）, hydraulic efficiency （2） and number of continuously stirred tank reactors （N）.     

我国社会治安综合治理的模式选择

社会治安综合治理是当代中国的一大创造,社会转型初期开始实行的社会治安综合治理模式难以应对多重社会矛盾的挑战和满足社会转型期公域治理的需要。鉴于我国公域之治对软法的倚重,现时期应以软法主导、硬法辅助和以软法整合分散硬法的两种路径构建我国社会治安综合治理的新模式。

Pancreatic somatostatinoma with obscure inhibitory syndrome and mixed pathological pattern

Somatostatinoma is a very rare neuroendocrine tumor that originates from D cells and accounts for less than 1% of all gastrointestinal endocrine tumors. The duodenum is the most frequent site for this tumor, followed by the pancreas. We here describe a 46-year-old Chinese woman who developed pancreatic somatostatinoma presenting with the characteristic “inhibitory” syndrome, but the symptoms were obscure and seemingly uncorrelated. This case is also unique for its large tumor size and mixed pathological pattern. Distal pancreatectomy was performed, and the patient has remained well since operation. As the syndromes of somatostatinoma may be obscure and atypical, clinicians should review all clinical findings to obtain an accurate diagnosis. Aggressive surgery is preferred to improve the survival.     

Metachronous contralateral testicular and bilateral adrenal metastasis of chromophobe renal cell carcinoma: a case report and review of the literature

Chromophobe renal cell carcinoma(ChRCC) metastatic to the testis has not,to the best of our knowledge,been reported in the literature.Nor have there been reports of delayed bilateral adrenal metastasis of ChRCC.Here we report a case of metachronous contralateral testicular and bilateral adrenal metastasis of ChRCC in a 70-year-old man who underwent right radical nephrectomy for RCC six years ago.He was admitted to the hospital because of left intrascrotal enlargement of two-month duration.Ultrasonography re...
