Zero net-liquid flow (ZNLF) is a special case of upward gas-liquid two-phase flow. It is a phenomenon observed as a gas-liquid mixture flows in a conduit but the net liquid flow rate is zero. Investigation on the liquid holdup of ZNLF is conducted in a vertical ten-meter tube with diameter of 76 mm, both for Newtonian and nonNewtonian fluids. The gas phase is air. The Newtonian fluid is water and the non-Newtonian fluids are water-based guar gel solutions. The correlations developed for predicting liquid holdup on the basis of Lockhart-Martinelli parameter are not suitable to ZNLF. A constitutive correlation for the liquid holdup of vertical ZNLF was put forward by using the mass balance. It is found that the liquid holdup in ZNLF is dependent on both the gas flow rate and the flow distribution coefficient.

In this paper, the concept of k-submesh and k-submesh connectivity fault tolerance model is proposed. And the fault tolerance of 3-D mesh networks is studied under a more realistic model in which each network node has an independent failure probability. It is first observed that if the node failure probability is fixed, then the connectivity probability of 3-D mesh networks can be arbitrarily small when the network size is sufficiently large. Thus, it is practically important for multicomputer system manufacturer to determine the upper bound for node failure probability when the probability of network connectivity and the network size are given. A novel technique is developed to formally derive lower bounds on the connectivity probability for 3-D mesh networks. The study shows that 3-D mesh networks of practical size can tolerate a large number of faulty nodes thus are reliable enough for multicomputer systems. A number of advantages of 3-D mesh networks over other popular network topologies are given. Compared to 2-D mesh networks, 3-D mesh networks are much stronger in tolerating faulty nodes, while for practical network size, the fault tolerance of 3-D mesh networks is comparable with that of hypercube networks but enjoys much lower node degree.

随着仪器分析的发展和广泛应用，针对有机化合物的化学鉴别方法研究近年来逐渐淡出化学学科前沿。然而化学鉴别方法由于其广泛的实用性和较低的成本，仍在有机定性与定量分析中占有一席之地。从典型有机物的化学鉴定分析方法入手，根据机理分类阐述了各类有机物的化学检验，并详细地讨论了几种机理较为复杂或易存在认识误区的化学检验手段，如茚三酮定性定量测试、双缩脲定性定量测试、Fehling与Benedict定性测试等。

依据嵌套于全球海洋环流模式中的1/6高分辨率中国近海环流模式模拟结果和海平面气压分布, 获得了渤海、黄海、东海和南海平均海面高度(海面地形)分布. 结果表明, 中国1985国家高程基准在全球平均海面之上24.7 cm, 中国沿岸海面南高北低. 与由大地水准测量得出的沿岸28个验潮站平均海面高度相比较, 标准偏差为4.8 cm, 拟合系数达95.3%, 通过线性回归订正, 标准偏差可减至4.5 cm, 表明模式结果已达到实际应用要求的准确度. 依据模式结果给出了中国近海1/6分辨率的平均海面高度值, 由此并可将大陆与岛屿高程相联系, 给出中国台湾、东沙、西沙和南沙的平均海面高度.

The vertical cable method for acquiring and processing pre-stack 3-D marine seismic data is based on the technology developed by the US Navy for antisubmarine warfare. In order to achieve the maximum utili- zation of vertical cable field data, a new separation method of the up-going and down-going wave fields of the vertical cable data processing was developed in this paper, which is different from the separation of the down-going and up-going wave fields of normal VSP data processing. In tests with synthetic modeling data and actual field data, this newly developed method performs well and is also computationally simpler without pre-assumption conditions.

Loop transformations, such as loop interchange, reversal and skewing, have been unified under linear matrix transformations. A legal transformation matrix is usually generated based upon distance vectors or direction vectors. Unfortunately, for some nested loops, distance vectors may not be computable and direction vectors, on the other hand, may not contain useful information. We propose the use of linear equations or inequalities of distance vectors to approximate data dependence. This approach is advantageous since (1) many loops having no constant distance vectors have very simple equations of distance vectors; (2) these equations contain more information than direction vectors do, thus the cliance of exploiting potential parallelism is *** general, the equations or inequalities that approximate the data dependence of a given nested loop is not unique, hence classification is discussed for the purpose of loop transformation. Efficient algorithms are developed to generate all kinds of linear equations of distance vectors for a given nested loop. The issue of how to obtain a desired transformation matrix from those equations is also addressed.
