如果闡釋學的循環闡釋(bermeneuitic circle)理論我們可以接受的話,那末對研究主體和研究對象之間的關係以及相應的研究方法不斷回思、省察,應成为學術與文化研究的不可或缺的一環。为此本期特闢“中國文化研究的檢討與展望”專欄,刊出三篇專論:一为李學勤先生的《走出“疑古時代”》,結合現代考古學的發掘成果,提出在本世紀產生巨大影響的古史辨學派,一方面對傳統學術向現代學術轉變起了解放思想的作用,另一方面也製造了不少“冤假錯案”,今天我們應該從“疑古”

“万国”与“红灯”的债务诉讼案

1戴景波——最近十多年来笔者所采访的第三位上海无线电二厂厂长,还未年过半百,却已两鬓斑白。双目尽管炯炯有神,但无法掩饰压在他心头的重重愁云。与前几任厂长截然不同,他一打开话匣子,所描绘的不是什么企业欣欣向荣的欢悦佳境,而是这家以生产"红灯"名牌音响产品闻名全国的大型国有企业,目前正笼罩在一片亏损的浓浓阴影之中。一场经济官司的出现,更无情地弄得戴景波陷入了晕头转向,无可适从的尴尬困境。说来令人难以置信,仅仅一笔300万元的债务,竟把这家有几千万元资产的大厂厂长逼上了被告的席位。那还是在1992年的春天,由于亏损严重而沉寂多年的上无二厂,看到了一线曙光。上海市为了建成现代化的大城市,确定把通信产业作为重点发展的三大支柱产业之一。

Adaptive foreground and shadow segmentation using hidden conditional random fields

Video object segmentation is important for video surveillance, object tracking, video object recognition and video editing. An adaptive video segmentation algorithm based on hidden conditional random fields (HCRFs) is proposed, which models spatio-temporal constraints of video sequence. In order to improve the segmentation quality, the weights of spatio-temporal con- straints are adaptively updated by on-line learning for HCRFs. Shadows are the factors affecting segmentation quality. To separate foreground objects from the shadows they cast, linear transform for Gaussian distribution of the background is adopted to model the shadow. The experimental results demonstrated that the error ratio of our algorithm is reduced by 23% and 19% respectively, compared with the Gaussian mixture model (GMM) and spatio-temporal Markov random fields (MRFs).

Metaphor in Cinema Revisited

The theory of rhetorical figures in cinema is highly problematic, besides it can be considered as outdated as the semiotic theory of cinema,1 yet it is convenient to reexamine the idea of＂cinematographic metaphor＂ in order to throw some light on the dominant idea of cinema as narrative medium. In this paper we will examine： （l） the supposedly existing metaphor of urban and industrial man as sheep at the beginn!ng of Chaplin＇s film Modern Times; and （2） the sequence of the awakening stone lion in Eisenstein＇s Battleship Potemkin as metaphor of the proletarian revolt against czarism. We will arrive to the notion of a purely metaphoric film, which together with Zavattini＇s ideal film showing 90 minutes in the life of a man to whom nothing happens, will helps us draw some conclusions about montage and narrativity in cinema. Especially interesting in this connection is the fact that symbolical shots as the mentioned ones are like description in literature, that is, they have nothing to do neither with the time of the story nor with the time of the discourse.

Concealed fault analysis based on the CT projection matrix

This paper proposes the concept of projection curves based on the theory of CT image reconstruction to probe the internal structure of the working panel prior to formal mining of the working panel.As well as reducing costs,this method provides safe and efficient excavation of the working panel.According to the results of the numerical model and the actual working panel,the new method has been proven to be accurate in detecting the location of the fault that extends into the face.Concealed faults of the internal working panel,as well as the start and end points of the fault,can be detected by this method.Engineering practice has proven that the method is highly reliable,has a highly decisive impact on faults for coal mining,and can be used to guide the safe mining of the working panel.

Application in soft sensing modeling of chemical process based on K-OPLS method

Aiming at the problem of soft sensing modeling for chemical process with strong nonlinearity and complexity,a soft sensing modeling method based on kernel-based orthogonal projections to latent structures(K-OPLS)is proposed.Orthogonal projections to latent structures(O-PLS)is a general linear multi-variable data modeling method.It can eliminate systematic variations from descriptive variables(input)that are orthogonal to response variables(output).In the framework of O-PLS model,K-OPLS method maps descriptive variables to high-dimensional feature space by using“kernel technique”to calculate predictive components and response-orthogonal components in the model.Therefore,the K-OPLS method gives the non-linear relationship between the descriptor and the response variables,which improves the performance of the model and enhances the interpretability of the model to a certain extent.To verify the validity of K-OPLS method,it was applied to soft sensing modeling of component content of debutane tower base butane(C4),the quality index of the key product output for industrial fluidized catalytic cracking unit(FCCU)and H 2S and SO 2 concentration in sulfur recovery unit(SRU).Compared with support vector machines(SVM),least-squares support-vector machine(LS-SVM),support vector machine with principal component analysis(PCA-SVM),extreme learning machine(ELM),kernel based extreme learning machine(KELM)and kernel based extreme learning machine with principal component analysis(PCA-KELM)methods under the same conditions,the experimental results show that the K-OPLS method has superior modeling accuracy and good model generalization ability.

An Economical Scheme for Cloning an Unknown M-Qudit Equatorial-Like State with Assistance

We propose a scheme to realize quantum cloning of an unknown M-qudit equatorial-like entangled state. The first stage of the protocol requires teleportation. After the teleportation is accomplished, the receiver can reestablish the original state. In the second stage of the protocol, with the assistance （through a single-particle projective measurement） of the preparer, the perfect copy of an original state can be produced at the site of the sender. Our scheme requires a single maximally entangled qudit pair as the quantum channel and three dits classical communication. The scheme is feasible at the expense of consuming local resources which include M - 1 ancillary qudits introduced by the receiver and additional bi-qudit operations. Moreover, we construct a sort of unitary transformations which ensure ancillary qudits are not necessarily introduced by the sender. Comparing to the previous protocols, the proposed protocol is economical due to that the cost of both quantum nonlocal resources and classical communication is lowest.

映·捉影——隐翅的花朵

花裙子少女坐在岸边吹起忧伤的柳木口琴曲，梦的星火缓缓沉坠入晨曦时分的河底。 ——你霸道地占据了我全部的视野。 年华像这足下的流水，将我的暗恋唱成一支液态的歌。

循环系統的X射線檢查

一、檢查範圍 循環系統的X射線檢查,祇能算是體格檢查的一部份,它應和臨床所見相輔進行,才能發揮其功效。否則是有限制而會發生錯誤的。它的主要用途如下: (一) 测定心臟血管的大小; (二) 從形狀之改變以推定心臟病之有無; (三) 察看搏動之高低、强弱、方向及其節律;
