In this paper, turbulent data obtained from the Damxung site during the Secondary Tibetan Plateau Science Experiment (TIPEX) in 1998 are used to study the characteristics of the turbulent spectra, turbulence transport, and the dissipation rates of turbulent kinetic energy, temperature variance, and humidity variance in the middle area of the Tibetan Plateau. The turbulent spectra of wind velocity, potential temperature, and humidity satisfy the-2/3 power law in the high frequency range. Horizontal transportation of heat and water vapor is negligible compared with vertical transportation under strong unstable conditions, and as the stability parameter z/L increases (where z is the observational height, and L is the Monin Obukhov length), horizontal transportation becomes dominant under near-neutral, neutral, and stable conditions. The non-dimensional temperature and humidity variances are 20% less than the temperature and humidity gradient variances. These deficits appear to increase as the absolute stability parameter increases. Moreover, the effects of turbulence transportation and pressure variance exist throughout the entire stability region.

The effects of organic additive, 3-amino-5-mercapto-1,2,4-triazole （AMTA） on bath stability, deposition rate, reaction activation energy, and Ni-P coating composition in acidic electroless nickel plating were investigated. Polarization curve method and infrared reflection spectroscopy were used to analyze the mechanism of the effect of AMTA on electroless nickel deposition. It was observed that AMTA improved bath stability, decreased the deposition rate, and increased the reaction activation energy. It was also revealed that AMTA decreased the phosphorus content and increased the sulfur content in Ni-P coating. In addition, AMTA inhibited the anodic oxidation of hypophosphite and accelerated the cathodic reduction of Ni^2＋. Infrared reflection spectroscopy result indicates that AMTA was adsorbed on the surface of Ni-P and interacted with Ni^2＋ to form an AMTA-Ni^2＋ compound. On the basis of the results of this study, the mechanism of the effect of AMTA on electroless nickel deposition was deduced.

Colonic lipoma is an uncommon tumor of the gastrointestinal tract. Most cases are asymptomatic, with a small tumor size, and do not need any special treatment. However, we encountered one patient with a giant submucosal lipoma, with a maximum diameter of 8.5 cm, which exhibited symptoms such as intermittent lower abdominal pain, changes in bowel habits with passage of fresh blood and mucus per rectum, abdominal distension, anorexia and weight loss. Unfortunately, the possibility of colonic malignancy could not be precluded and leffc hemicolectomy was planned. The exact diagnosis of this special case was accomplished by intraoperative pathology. In the end, local resection was performed instead of left hemicolectomy. To the best of our knowledge, colonic lipoma exceeding 8 cm in diameter has not been previously reported. We, therefore, present this case and discuss age and sex factors, clinical and histopathological findings, diagnostic methods and treatment by reviewing the available literature, to serve as a reminder that colonic lipoma can also exist in patients with significant symptoms. In addition, intraoperative pathology should be investigated in those doubtful cases, so as to guide the exact diagnosis and treatment plan.

Forestry Studies in China 2011年第2期13卷 85-96页

The average temperature of northeastern China is expected to increase 2.22 and 2.55℃ under two scenarios selected from the Intergovemmental Panel on Climate Change （IPCC）, i.e., A2 and B2, during the 2040s （2041-2050）, which will have an impact on fire activities in those areas. We calculated the output of regional climate models, using the Canadian Forest Fire Weather Index （FWI） on a scale of 50 km × 50 km. Meteorological data and fire weather index were interpolated to a scale of 1 km × 1 km by using ANUSPliN software. The results show that the model of Providing Regional Climate for Impacts Studies （PRECIS） had the ability to provide good temperature and precipitation estimates of the study area in the baseline period, by simulation. In the 2040s the mean FWI values of the study area will increase during most of the fire seasons under both selected scenarios, compared with the baseline period. Under scenario B2 the peak fire season will appear in advance. The changes of FWI ratio （2×CO2/l ×CO2） show that the potential burned areas will increase 20% under scenario B2 and lightly increase under scenario A2 in 2040s. The days of high, very high and extreme fire danger classes will add 5 and 18 d under scenarios A2 and B2, respectively. It suggests adapting the climate change through improving fuel management and enhancing the fighting abilities.

Biliary papillomatosis （BP） is an extremely rare pathological condition, which is characterized by papillary proliferation of the bile duct epithelia. Although initially thought to be a benign entity, this tumor has been shown to have a tendency for malignant transformation. As reported in the literature, malignant degeneration occurs in 20% to 35% of cases. Because patients typically present with abdominal pain, obstructive jaundice and fever, they are usually mistaken as having more serious pathology such as cholangiocarcinoma, cholangitis and so forth. In general, the rate of preoperative diagnosis is very low. At present, the number of published articles about this illness is limited, mainly as single case reports. In addition, the diagnosis, treatment and prognosis of BP have not been well known. We, therefore, discuss age, gender, clinical manifestations, diagnostic approaches, histopathological findings, treatments and prognosis by reviewing the clinical data of eighteen patients with BP treated in our hospital, so as to better understand this rare illness.

自邵雍先天学倡明以来,学者多以朱(熹)释邵(雍),褒贬不一。邵雍的先天易学,是以宇宙生化的方式铺开,通过纵向的体用和横向的变应关系,经由内在象数的交易生变,而形成先天图,揭示天道的生化之机。先天之宇宙论定位是体用、变应和交变的宏观视域。体用与变应是先天的两种作用方式。体必交而生后,体以变为用,变必有应。体用与变应又因交变常交织。邵雍的先天易学,本于先天、体用、交变和变应四个逻辑架构,于先天图之形成过程、图式结构和功用发挥上一以贯之。朱熹执着画前之易及其自然流露,从横图着眼阐发先天图某些阴阳流行对待之蕴,亦谓有所得。但其未能透彻邵雍之先天、体用、交变、应变,故于先天易学为别解者多。

清张惠言对虞翻卦变易注做了月体八卦消息的注脚,然其说源于虞氏,实不同于虞氏。张惠言改造《易纬》和郑玄宇宙生化的观点,发展成乾元坤元一物两体的思想,乾元是宇宙生化的源动力,乾元坤元一物两体是易道阴阳消息和卦画生成开显的基本结构。基于此,张氏一方面诠释了月体八卦与"乾坤立八卦"相为表里的关系,巧妙地将二者统一起来,另一方面以月体八卦消息为统摄,融十二辟卦、五十二杂卦等为一体,八卦消息成六十四卦,最终形成有别于前人十二消息卦变的月体消息卦画系统。张氏承汉人卦变消息旨趣,有接续之功,其月体消息卦画说于卦画系统、阴阳消息、《周易》经传之辞的"画一"问题上提供了独特的视野和诠释,对易学的发展有着重要贡献。

传统文化的发展,时的理论建构,都离不开易学时论。易学时论,大抵有两种:一种以卦画言,为以时解易;一种以义蕴言,为时的哲学。以时解易,发起于《易传》,形成于王弼、程颐,成熟于胡炳文。"时"的哲学发轫于古经,形成于《易传》,成熟于宋元易学,由于象数派和义理派的努力,时逐渐上升到宇宙本体的地位,呈现出象数、义理多样的结构模式,形成象数派、义理派对时不同的运用工夫。易学时论,突显了古经的思想意蕴和易学内容体系,是时理论和传统文化的重要组成部分,对当今人生社会的发展、创新和与时俱进的主题也有着重要的现实价值。
