案头与场上——以汤显祖传奇落场集唐诗见明清曲家戏剧观

汤显祖传奇作品落场诗大量采用集唐形式,尤其是《牡丹亭》,不仅数量多,而且质量高,成为传奇落场集唐诗运用的典范佳作。然而大量文辞过于典雅的落场集唐诗却显示出汤显祖剧作案头化倾向严重。部分明代曲家有意识地纠正这一背离戏曲作为舞台艺术本质的倾向,强调场上演出的重要意义,表现之一就是改编汤作时或改或删落场集唐诗。从晚明清初传奇创作实践来看,剧作家已经找到"案头场上,两擅其美"的办法。

环形透镜暗场落射照明系统设计及其焦移特性的研究

环形透镜暗场落射照明系统越来越多被应用在特型显微镜上。该系统设计的难点是当采用现有的光学设计CAD软件设计计算时,由于环形透镜所具有的焦移特性的影响,难以保证预期的设计效果,也在一定程度上制约了该系统的推广应用。通过理论分析、实验论证和用自编制的照明设计CAD软件进行光线追迹,较好地确定了该系统的焦移量。并在此基础上提出了照明设计CAD与光学设计CAD软件互动迭代的设计方法。

Alterations of the Nitrogen Mineralization Rates in Soils of Forest Community Depending on the Ski Run Construction (Mount Uludag,Bursa,Turkey)

Since 194os, Mount Uludag （Bithynian Olympus） has been considered famous with winter sports center in Turkey. In addition, it is one of the rare places because of its plant diversity and is also one of the important plant areas of Turkey. The ski run constructions are rapidly increased in the past decades in the alpine and subalpine belts of the mountain. Rate of nitrogen mineralization and some properties of soft were investigated in the soils of the three ski runs and undisturbed neighborhood forest sites. These ski runs are at the upper part of the forest belt in the mountain. Abies bornmuelleriana forest community is the postclimax and very sensitive to destruetion. The rates of the nitrogen mineralization in the soils were determined in controlled conditions （60% water-holding capacity, 20℃）. Nitrification and nitrogen mineralization were in the ski run inside where the natural recovery started, increased compared with the outside of the ski runs. Waterholding capacity, organic carbon, and total nitrogen were decreased in the massive damaged ski run, and due to these changes, the rates of mineralization and nitrification were also decreased.

一场没有落下的雪

母亲回来，说外面下冰了。我打开窗户，伸出手．小冰砾蹦蹦跳跳地在掌中舞蹈。我知道．这个冬天完全地来到了。来了尽管会走．但它会留下一些东西的。就像春天会留下绿芽。夏天会留下红花．秋天又会留下果香一样．

Characteristics of ground behavior of fully mechanized caving faces in hard thick seams

It is showed in practice that the support load and its fluctuation is large, the periodic weighting is obvious and can be divided into two kinds, the large and small pressure, sometimes the behavior of the large pressure is very violent in hard thick seam caving faces. These are obviously different from those of the generally soft or medium hard seam caving feces. All above these are summarized, and the causes aroused these are researched. Finally the powered support selection of hard thick seam caving faces is discussed.

Coalescence behaviour of water droplets in water‐oil interface under pulsatile electric fields

In this research, the deformation of water droplets in sunflower oil-interface under pulsatile electric field was studied experimentally. Three types of coalescence were observed:(i) complete coalescence,(ii) incomplete coalescence and(iii) no-coalescence. The first type is desirable because of leaving no secondary droplets. The second type that produced secondary droplets which caused by necking process, due to extreme elongation of droplets(mostly small droplets), was undesirable; because the small droplets were more difficult to coalesce and remove. The no-coalescence was caused by very fast coalescence and extensive pushing of droplet into the continuous phase. In this work the process was operated with the utilization of a batch cylindrical separator with high voltage system. The lower part of the cylinder was filled with the aqueous phase and its top part was filled with sunflower oil to form an interface between the two phases. The effects of electric field strength,frequency, and waveform types were investigated. It was found that, the ramp-ac waveform was the best waveform, avoiding the production of secondary droplets and in this case the frequency also played an important role.

Spontaneous caving and gob-side entry retaining of thin seam with large inclined angle

Based on the research method of combining simulation analysis with field testing by distinct element process UDEC, we have analyzed the roof deformation and failure laws and roadway support technology of gob-side entry retaining in a thin seam with a large inclined angle. The results show that during exploitation in seams with large inclined angle, rotational subsidence of the main roof under the gob area is small and can maintain balance, so there is no need to provide artificial permanent support resistance for the main roof near the upper side to control rotational subsidence. Obstructed by the dense scrap rail,waste rock from the immediate roof caving slides from the upper gob area to the lower area and fills it,which strikes a balance between the immediate roof under the goaf after it fractures into large pieces and filling waste rocks.

From Sunset Winter to Caetano＇s Spring： The Importance of a Song Contest in the Portuguese Music Scene of the 1960＇s and 1970＇s

I propose to introduce a few lines of analysis for the RTP Song Contest （Portuguese Radio and Television Song Contest--Festival RTP da Cancāo）. I intend to raise a few questions that will help us to understand the role of this competition in the Portuguese musical and cultural scene of the 1960s. RTP Song Contest is the longest television song contest in Portugal. This competition went through several crucial moments in the recent history of Portugal, witnessing the change from dictatorship to democracy. In late 1960s, still under the authoritarian regime, several social changes took place and music played an important role in these changes, as several studies have documented. In 1969, Portugal bet on Simone de Oliveira to bring us the prize, but the result was not the expected. This event brought us many questions about the importance of the Portuguese participation in the Eurovision Song Contest and the faimess of the European evaluation. This paper intends to reflect the implications of this particular event and the importance of the Contest for the Portuguese music scene at the end of the critical 1960＇s. With this paper, I intend to introduce some lines of analysis of the first ten years of the Portuguese Radio and Television Song Contest （Festival RTP da Cang6o--RTP Song Contest）. I intend to raise a few questions that will help us to understand the role of this competition in the Portuguese musical and cultural scene of the late 1960s and 1970s, based on the study of the daily press. RTP Song Contest is the most long-life television contest in Portugal. For this reason, it is important to make a short historical overview of this period and the history of television in Portugal. At the same time, the analysis of statistical data of audiences enables us to understand the television phenomenon in the late 1960s.

Hard-Core Bosons on a Two-Dimensional Square Optical Superlattice

In this work,we theoretically study hard-core bosons on a two-dimensional square optical superlattice at T = 0.First of all,we present the mean field phase diagram of this model in terms of the chemical potential μ and the alternating potential strength △.Besides a superfluid(SF) phase at △ = 0 and a charge density wave(CDW)phase in the large △ at half filling,we demonstrate that a supersolid(SS) phase emerges in the moderate △.Then,we focus on the μ = 0,e.g.,half filling case,using large-S semi-classical spin-wave approximation to study the SS to CDW quantum phase transition.In particular,we calculate the ground-state energy and the superfluid density at the level of1/S correction.We then compare the spin-wave results with the large scale quantum Monte Carlo(QMC) simulations using the cluster stochastic series expansion(CSSE) algorithm,and find that while the spin wave method is intuitive with clear physical pictures,the quantum critical point is quite different from that of numerical results which is believed to be accurate.We suggest that as simple as it is,this model still exhibits strong quantum fluctuations near the quantum critical point beyond the power of semiclassical spin-wave approach.

Numerical simulation of parachute Fluid-Structure Interaction in terminal descent

A numerical simulation method for parachute Fluid-Structure Interaction （FSI） problem using Semi-Implicit Method for Pres- sure-Linked Equations （SIMPLE） algorithm is proposed. This method could be used in both coupling computation of para- chute FSI and flow field analysis. Both fiat circular parachute and conical parachute are modeled and simulated by this new method. Flow field characteristics at various angles of attack are further simulated for the conical parachute model. Compari- son with the space-time FSI technique shows that this method also provides similar and reasonable results.
