If the original BCFs satisfy perfect reconstruction condition,the new ones constructed with this algorithm also satisfy perfect reconstruction condition.

While the selling price of the remanufactured tractors was only 50%~60% of the new ones, and their life time was not less than 80% of the new machines.

Compared with the old excipients and process energy, the cost of the new ones declined 10 Yuan/10000 tablets, of which the cost of materials was 7.78 Yuan/10000 tablets, and the coat of energy was 4.4 Yuan/10000 tablets.

This paper detailedly discusses a few kinds of new network storage technologies based on traditional network storage technologies,and in order to the readers know the network storage technologies roundly,it compares the traditional network storage technologies with the new ones based on transfer protocols and transfer modes.

Moreover, remyelination occurred synchronously throughout the optic nerve, with the same time course in the pre-existing Schwann cells, the new ones that colonised the second injury, and the CNS oligodendrocytes elsewhere.

In thissurvey, our goal is to classify all these paradigms,especially the new ones, in order to help network andsystems administrators design a management application, and choose between mobile code, distributedobjects, intelligent agents, etc.

However, a valuable knowledge can be learned from the analysis of previous projects and applied to the new ones.

All tubes had fungal colonization.DSC showed deterioration in all tubes including the new ones; adding Candida albicans had no additional effects.

Twenty alkaloids including the new ones arundavine and arundafine were isolated from the plant alkaloids.

This paper describes the concrete process of using BASIC to realize theorem proving on a mini-computer PDP-11-03. The only rule of inference used is a refinement algorithm-the Unit Binary Eesolution. A few of technics as follows:1. The subsumption test. This technic can be used to delete some irrelevant and redundant clauses. With the "Fast-Search-Method", some unnecessary teats can be avoided. For instance, let C1, C2, …, Cn be the given old unit clauses and D1, D2, …, Dm be the new ones. If D1, D2, …,...

This paper describes the concrete process of using BASIC to realize theorem proving on a mini-computer PDP-11-03. The only rule of inference used is a refinement algorithm-the Unit Binary Eesolution. A few of technics as follows:1. The subsumption test. This technic can be used to delete some irrelevant and redundant clauses. With the "Fast-Search-Method", some unnecessary teats can be avoided. For instance, let C1, C2, …, Cn be the given old unit clauses and D1, D2, …, Dm be the new ones. If D1, D2, …, Dm. do not subsume each other, m(m-1)/2 times of search can be saved.2. The test of the ordinal number of clauses. To resolve a unit clause, say clause m, against a nonunit clause, say clause n', we first find the last unit clause, say clause m', which is used to obtain clause n'. If m is less than m', we resolve clause m and clause n'; otherwise, they are not resolved. (Using it, we can avoid repeatedly generating the same unit clause.)3. The supporting set. The supporting set can be used to avoid performing any resolution in the basic axioms.4. The programming technic. The nest structure of ALGOL is introduced into BASIC programs so that only one-dimension string array and a few simple variables are needed. Chain structure is used to realize the exchange between the Polish notation and the usual notation of clauses. The dialogue between the user and computer can be used to speed up finding proofs of theorems.

The theoritical results of systems of inbreeding have been discussed in this paper.The general formulae for the heterozygote frequencies.Inbreeding coefficients and the rates of inbreeding for systems of full sib.Alternative parent-offspring and unrestricted Parent-offspring mating involving a single autosomal gene substitution are derived by extrapolation from the change of the heterozygote frequencies of ensuing generations when the population in the initial generation is at equilibrium.These formula are different from what are described in the classical memoirs.By the new ones the evaluation of the parameters Ft.Ht and ΔFt given generation t can be made more easily.The limiting values of Ft and Ht for all of three sys- tems of inbreeding have been verified strictly.The exact limiting value of ΔFt for systems of full sib and alternative parent-offspring mating has been found.It is (2/((1+5~(1/2)))~2) and is the core of the rates of inbreeding of all generations.These rates of inbreeding fluctuate by the core up and down alternately and finally approach to it with the range going down each passing generation.

1.规则近交系统的近交系数及杂合体频率的变化规律在经典文献中被归结为一些世代递推公式,以此描述群体的遗传结构。这里,我们通过研究相继世代杂合体频率的变化与平衡的起始群体基因裂频率的联系,为常体的两等位基因位点,导出表达若干近交系统的杂合体频率,近交系数及近交率变化的通式。2.用本文中的公式可以简单地直接计得任一给定世代 t 的近交系数,杂合体频率及近交率,而不象经典公式需要依赖所求参数在以前世代的值。3.严密地求证了全同胞交配系统,交替型及无限型亲子交配系统的近交系数及杂合体频率的极限值。4.求得了全同胞交配系统及交替型亲子交配系统的近交率的准确极限值,它等于(2/(1+5~(1/2))~2)。5.研究了在全同胞交配系统及交替型亲子交配系统中,近交进程的精细变化。发现各世代的近交率以极限值(2/(1+5~(1/2))~2)为中心,左右摇摆,摆幅逐代减小而趋于该值。

According to the end product requirements and the raw material variations, through comparing the old equipment and technology with the new ones, the author suggests that the chutefeed card, the pre-drawing frame for polyester sliver and the electronic yarn clearers, high coefficient of twisting factor for roving, the new technology of slashing and warping must be adopted in the cotton spinning and weaving processes. The article also investigates the symbol representing the equipment advance.
