Quantum effects play an enhancement role in p-p chain reactions occurring within stars. Such an enhancement is quantified by a wave penetration factor that is proportional to the density of the participating fuel particles. This leads to an innovative theory for dense plasma, and its result shows good agreement with independent data derived from the solar energy output. An analysis of the first Z-pinch machine in mankind＇s history exhibiting neutron emission leads to a derived deuterium plasma beam density greater than that of water, with plasma velocities exceeding 10000 km/s. Fusion power could be achieved by the intersection of four such pinched plasma beams with powerful head-on collisions in their common focal region due to the beam and target enhanced reaction.

Fusion power output is proportional not only to the fuel particle number densities participating in reaction but also to the fusion reaction rate coefficient （or reactivity）, which is dependent on reactant velocity distribution functions. They are usuMly assumed to be dual Maxwellian distribution functions with the same temperature for thermal nuclear fusion circumstances. However, if high power neutral beam injection and minority ion species ICRF plasma heating, or multi-pinched plasma beam head-on collision, in a converging region are required and investigated in future large scale fusion reactors, then the fractions of the injected energetic fast ion tail resulting from ionization or charge exchange will be large enough and their contribution to the non-Maxwellian distribution functions is not negligible, hence to the fusion reaction rate coefficient or calculation of fusion power. In such cases, beam-target, and beam-beam reaction enhancement effect contributions should play very important roles. In this paper, several useful formulae to calculate the fusion reaction rate coefticient for different beam and target combination scenarios are derived in detail

用有限元方法计算了活体胆囊中胆汁的瞬态流场。采用了CT(计算机断层扫描),造影等技术获得运动的边界条件。采用了罚函数公式系统和移动三角形单元获得了轴对称胆汁流动的流场。计算结果表明,垂直于中轴的截面上存在着明显的胆汁回流,回流与出流共同形成了收缩胆囊内的轴对称涡流,这与以前的预料十分吻合。

本文从流体力学理论出发,采用CT、X线造影和B超等技术,获得了人体椭圆类胆囊边界收缩运动的数学模型。并应用有限元方法在国际上首次计算出人体椭圆型轴对称胆囊胆汁的瞬态流场,获得了轴对称牛顿胆汁流动的流场分布。从而首次实现了人体胆囊胆汁流场计算的活体研究。从理论上论证了涡流是胆囊结石形成的力学机制,并得到下述结论:(1)收缩胆囊的轴线附近存在着一般快速的胆汁出流;(2)流场中心截面附近存在着两个旋向相反的涡流区,其中靠近轴线逆时针方向旋涡区强度较高;(3)胆汁流场的衰减规律与胆囊收缩舰律大致相同;(4)胆囊结石的形成与涡流有关。

A single cathode with a cascaded bias voltage arc plasma source has been developed with a new quartz cathode chamber,instead of the previous copper chambers,to provide better diagnostic observation and access to the plasma optical *** cathode chamber cooling scheme is also modified to be naturally cooled only by light emission without cooling water to improve the optical thin performance in the optical path.A single-parameter physical model has been developed to describe the power dissipated in the cascaded bias voltage arc discharge argon plasmas,which have been investigated by utilizing optical emission spectroscopy（OES） and Langmuir *** the experiments,discharge currents from 50 A to 100 A,argon flow rates from 800 sccm to 2000 sccm and magnetic fields of 0.1 T and 0.2 T were *** results show：（a） the relationship between the averaged resistivity and the averaged current density exhibits an empirical scaling law as η∝ j^（-0.63369） and the power dissipated in the arc has a strong relation with the filling factor;（b） through the quartz,the argon ions optical emission lines have been easily observed and are dominating with wavelengths between 340 nm and 520 nm,which are the emissions of Ar^＋-434.81 nm and Ar^＋-442.60 nm line,and theintensities are increasing with the arc current and decreasing with the inlet argon flow rate;and（c） the electron density and temperature can reach 2.0 × 10^19 m^-3 and 0.48 eV,respectively,under the conditions of an arc current of 90 A and a magnetic field of 0.2 *** half-width of the ne radial profile is approximatively equal to a few Larmor radii of electrons and can be regarded as the diameter of the plasma jet in the experiments.

互动性是数字媒介有别于传统媒介的典型特征。互动技术在叙事中的嵌入,从根本上改写了经典叙事赖以存在的结构问题,由此引发了叙事学的数字转向。互动性,沿着叙事语义和叙事规则两个维度,深刻地影响着叙事性的内涵。数字媒介的互动叙事之所以成为可能,离不开交互界面这一特殊的程序装置。界面既是信息存在的居所,亦是互动发生的条件,其在叙事可供性维度上拓展了一种全新的叙事关系。融合新闻的互动叙事,主要沿着路径互动、情节互动和环境互动三个维度展开,相应地便形成了三种基本的互动形式及实践。在路径互动维度,互动叙事基于“遍历”这一技术方案,打开了被折叠的可能世界,并以此为认识方法,抵达未知的现实世界;在情节互动维度,互动叙事通过对时间的自主“操控”以及对空间的自由“转换”,使得基于互动的故事建构成为可能;在环境互动维度,互动叙事基于普适计算的理念与实践,将叙事搬到了现实环境之中,使得环境本身成为一种界面,从而在人与环境的互动中构建了一种全新的信息生成模式。
