以危险方法危害公共安全罪的特征分析——兼析危险驾驶肇事的刑法评价

对以危险方法危害公共安全罪的特征进行分析,并在此基础上进一步考量危险驾驶肇事的案件是否适用以危险方法危害公共安全罪。认为虽然以危险方法危害公共安全罪的外延是不明确的,但其核心属性是可以确定的。以刑法规范评价的视角,用本罪主客观特征考量危险驾驶肇事的性质,可见危险驾驶行为通常不属于本罪的"危险方法",危险驾驶肇事的主观心态通常不是故意,因而危险驾驶肇事的案件通常不适用本罪。     

广东三水盆地华涌组火山岩分布特征及地球动力学意义

以区域钻井资料、野外露头勘查、岩石样品地球化学分析为依据,结合近年来三水盆地火成岩研究成果,细致刻画盆地内华涌组火山岩的岩性、时空分布以及喷发特征.华涌组火山岩以流纹岩、粗面岩与玄武岩互层为主,呈典型双峰式组合.根据岩性变化特征在华涌组沉积期内识别出四个火山喷发亚旋回,各旋回均由酸性流纹岩或粗面岩喷发开始,以基性玄武岩喷发结束.其中第一、二亚旋回以中心式喷发为主;第三、四亚旋回以裂隙溢流喷发方式为主,火山活动逐渐由强减弱.通过与周边地区区火山岩分布特征的对比研究,可以确定三水盆地华涌组火山岩是在拉张背景下发育的大陆裂谷型火山岩,是南海开裂初期的重要物质记录.

Studies on gorgoderid digeneans from Australian and Assian Freshwater fishes

Pseudophyllodistomum gen. nov. is proposed for a section of Phyllodistomum Braun, 1899. The new genus is distinguished by the simple form of the uterus, the eggs which reach over 60 μm long in length, the saccular excretory bladder, the 2[3 + 3 + 3) + (3 + 3 + 3)] = 36 flame-cell formula, the metacercaria which may have fully developed genitalia and is parasitic in decapod crustaceans, the use of corbiculid bivalves as first intermediate hosts, and the cercaria which has a long tail not enclosing the cercarial body. Two species, P. johnstoni sp. nov. and P. murrayense sp. nov., are described from Australian freshwater fish and five new combinations of previously described Phyllodistomum species from Asian freshwater fish are proposed — P. macrobrachicola (Yamaguti, 1934) comb. nov., P. lesteri (Wu, 1938) comb. nov., P. srivastavai (Rai, 1964) comb. nov., P. lucknowense (Pandey, 1970) comb. nov. and P. mingense (Tang, 1985) comb. nov. The first intermediate host of P. johnstoni is a Corbiculina species. The long-tailed cercariae infect the gonads of palaemonid prawns, Macrobrachium spp., in which they grow to unencysted metacercariae which may have fully developed genitalia. The metacercaria of P. murrayense also infects a Macrobrachium species. The evolution of the Gorgoderinae is discussed and it is suggested that, prior to the erection of Pseudophyllodistomum, Phyllodistomum may have encompassed as many as five different phylogenetic lines, each with similar adult morphology but distinguishable by life-cycle characters. It is postulated that more study will lead to further division of Phyllodistomum.

具有点故障的超方体中经过指定路的无故障圈

本文研究了在含有故障点的n维超立方体Qn中通过给定路的无故障圈问题,本文得到以下结果：设n≥3,2≤h〈n,F V（Qn）且｜F｜〈n-h,则在Qn-F中，每一条长度等于h的路P都包含在每个偶长度从2h＋2到2″-2｜F｜的圈中，并且当｜F｜〈h-1 时，则路P还包含在长度等于2h的圈中。     

奥运形象建设的精神源动力

体育作为人类社会的文化现象,其产生与发展已经有数千年的历史.然而在体育发展的过程中,始终伴随着体育发展的就是不朽的奥运精神.通过对体育的起源、发展到繁荣以及奥运精神内涵的论述和分析,认为奥运之所以到现在还具有如此强大的生命力,是因为不朽的奥运精神,而这种精神也正是奥运形象建设的源动力.     

THE MULTIPLICITY OF ZERO AND LIMIT CYCLES FOR ABEL EQUATIONS

In [1], AlwaSh and Lloyd investigated the nUmber of hot cycles surrounding a critical pointof focus take for polynOInial two dimensional systems. Under polar coordinates, the discussedsystems can be transformed into Abel equstion of the form:2 = a(t)z' g(t)z' 7(t)z, (1)with periodic boundary condition:z(0) = z(W). (2)When multiplicity p of solution z = 0 for equation (1) is larger than one, without lOss ofgeneralityt we can assume 7(t) = 0 for t E [0, w]. Let pm denote the m~ multiplic…
