In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.
本文首先针对覆晶底部充填进行相关理论推导、实验与模拟,探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响;即依据相关参数建立模型进行底部充填实验,同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟,在完成理论探讨、实验与模拟分析之后,交叉比较理论、实验与模拟分析结果,归纳出影响底胶充填流动之因素,由结果显示在凸块密集度较高的区域,凸块可以帮助流动,但是在凸块区后方的沟槽区域则因为凸块区所提供之流量不足,所以会造成波前落后的现象,另外藉由修改凸块与沟槽配置的关系,可以有效的控制波前形状的变化情形,避免产生包风现象。

Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.

Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition,and delusion, and appearance, that alluvion which covers the globe,through Paris and London, through New York and Boston and Concord,through Church and State, through poetry and philosophy and religion, till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake; and then begin,having a point d'appui, below freshet and frost and fire, a place where you might found a wall or a state, or set a lamp-post safely,or perhaps a gauge, not a Nilometer, but a Realometer, that future ages might know how deep a freshet of shams and appearances had gathered from time to time.
让我们定下心来工作,并用我们的脚跋涉在那些污泥似的意见、偏见、传统、谬见与表面中间,这蒙蔽全地球的淤土啊,让我们越过巴黎、伦敦、纽约、波士顿、康科德,教会与国家,诗歌,哲学与宗教,直到我们达到一个坚硬的底层,在那里的岩盘上,我们称之为现实,然后说,这就是了,不错的了,然后你可以在这个point d'appui 之上,在洪水、冰霜和火焰下面,开始在这地方建立一道城墙或一个国土,也许能安全地立起一个灯柱,或一个测量仪器,不是尼罗河水测量器了,而是测量现实的仪器,让未来的时代能知道,谎骗与虚有其表曾洪水似的积了又积,积得多么深哪。

On the basis of investigating analytic proposition and synthetic proposition, the paper gives some comments on Quine's critique on distinction of the two propositions, illustrating that Quine's critique cannot deny their distinction and only show they are two typical fuzzy conceptions, so we should grasp the dialectical mechanism of their relative distinction and inter-permeation by fuzzy thinking methods.
在考察分析命题与综合命题的基础上,对奎因分析命题与综合命题之区分的批判进行了评述,说明奎因的批判并不能否认分析命题与综合命题的区分,而只是表明了"分析命题"与"综合命题"是两个典型的模糊概念,因而需要运用模糊思维方法去把握它们既相对区分又相互贯通的辩证机理。

Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment
重金属含量均低于新鲜尾矿,但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%),往下大幅度降低,表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用,而次氧化带的淋溶作用造成了金属元素的大量流失;(4)与新鲜尾矿相比,硬化层中铅的可迁移性大大降低,硬化层之下尾矿样品中铅的可迁移性也不同程度降低,这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故;(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大,其中对锌的可迁移性影响最大,铜的可迁移性与铁比较相似,铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4);(6)为了减少尾矿污染和修复矿山环境,人们提出了各种不同的尾矿覆盖方案,本文的研究结果表明,这些方法不一定能够有效地阻滞污染元素的迁移。
