We have obtained the alpha- alpha interaction for the coupled channels in which the internal structure of the alpha particles is approximately represented by a two-state system.In this model, the alpha-alpha interaction is represented by a 3*3 matrix. By using an unitary transformation, we obtain an exact expression for the phase shift in terms of the potential parameters which is determined from the two-body scattering data.

The paper presents a detailed study of a discrete time common control delay queuing system. The system considered in the paper has a single server and single common control operator. Cutomers arrive following a binomial distribution, both the operating time of the common control service time of server are independent random processes with general probability distribution. Queue discipline is first-come first-served. The generating functions of the stationary state probabilities of the system on the regeneration points being defined and of the waiting time probabilities are presented. The mean queue length and mean waiting time are also obtained.

We use the quasiparticle approach and the method of the equation of motion to study a one-dimensional solid with electron-phonon interaction.After transforming to a moving frame, an energy gap in the single electron energy spectrum with a width at v=0;△=16Efe^-1/λ is obtained, which has the same form as in pairing theory. We also obtain a state in which the electrons will move with the phonons in an organized way. Thus the conductivity will increase extrodinary if v is sufficiently small. This result agrees with the experimental phenomenon, which was observed recently in some one-dimensional organic solid.
中文字根式輸入之簡化

交大曾提出以499個字根，配合九種結合符號，可將48,713個中文字應用於電子計算機(1,2)。基本上每二字根均應有結合符號連接(1)，但經過適當處理，則可將定位符號省去近93%(4)。現本文再就使用之結合符號，做更進一步的探討。根據9,060個基本用字(基本用字8,533個，再加參照字形527個)分析各字根所接用之結合符號，知可利用計算機之程式設計，將結合符號全部省去。當機器組字時，只要收到連續字根，即可將結合符號自動補入字根間或字根之最前與最後，因而得到造字的字根結構式。由統計結果知：平均每一中文字使用1.98個字根及1.16個結合符號(4)。故如省去結合符號時，平均每字只按鍵1.98次，則中文輸入之速率將增加1.585倍，且省去結合符號，由計算機程式處理，可得標準之結構式，因而中文在計算機處理上將方便甚多，而有助於電子計算機之中文化。

This paper defines a new kind of language. The language is called CHITAL-CHInese table TAbulation Language. The main purpose of the CHITAL is used for describing a table including Chinese characters. The purpose of this language is so general that a fairly complicate table and even a simple graph can be described. In addition to defining the language, this paper describes the implementation of an interpreter for it and gives some illustrated results.

This paper deals with a specific class S' of entire functions and finds sufficient conditions on the Maclaurin coefficients of an entire function f(z)ε S',so that there exists a parabolic region H, free of zeros of f(z) and all its partial aums, in the right-half plane symmetric about the nonegative real axis. Moreover, we study the asymtotic bahavior of the width function Gf of f(z)ε S' and solve a conjecture an Gf partially.

A new approach, based on a double-pulse-discharge technique, has been successfully performed on a LE CO2 laser. This technique consists of two consecutive discharges. First, the preionization discharge, which is higher in voltage and less energetic. Then, after some delay time, the main discharge follows. TEA laser can perform double-discharge effectively, but it requires auxiliary preionization-electrodes.Double-discharge technique has been only possible for multi-electrode lasers[1]. Now, the new technique developed by us has been demonstrated to be capable of solving the aboved-mentioned difficulty beneficially. The discharge circuit is mainly constructed by using capacitors and spark gaps, and is ready to apply to any two-terminal discharge tube. Comparosons between this device and the same discharge tube[4,5] usinng conventional excitation technique show that the laser energy and overall efficiency can be increased at least by a factor of 1.5, and the optimal E/P ratio was decreased. Furthermore, the improved discharge conditions also enable arcingfree operation with higher pressure than that of applying conventional discharge technique. Up to the present time, this is the only preionization technique for the LE CO2 laser.

The electrical properties of barium titanate films approximately from 1000Å to 5000Å thick, prepared by electron beam evaporation onto silicon(n or p) substrates in high vaccum system were investigated. The effects of substrate heating during deposition, different temperature and gases annealing process after deposition were also studied. The electrical characteristics of the film, including the dielectric constant, loss tangent, conductivity, metal-insulator-semiconductor surface properties, and ferroelectricity were also investigated. It was found that the room temperature substrate deposition and the annealing temperature below 120℃,would give the relative dielectric constant up to 1000 for both n- and p-type silicon substrate. The ferroelectric transition of barium titanate-silicon MIS structure was observed. The hysteresis behavior of barium titanate silicon MIS structure was first demonstrated and seemed promising to be used as non-voltile memory devices.

Surface conductivities of waveguides having different wall conditions were examined via the insertion loss technique and Q-technique. It is found that ordinary copper plated waveguide samples are usually about 12% to 19% above the calculated value based upon a wall conductivity 5.8 10^7 mho/m in the frequency range of 40 to 110 GHz. When the copper waveguides described above are subjected to additional surface treatment (usually imparted to promote dielectric bonding) , the losses may or may not change depending on the nature of the surface treatment. for example, a chromated (probably Cr2O3) layer up to 300 A will not cause significant added losses in the mm wave frequency band. On the other hand, a surface treatment consisting of a grown copper oxide film (Cu2 and CuO)will cause a significant increase in loss relative to plated but untreated copper. This additional loss is approximately 20% at 96 GHz.

Two central questions have been raised and discussed in this paper: (1) what role the transport sector should play in the developing process ? (2) what relationship can be found to exist between transport development and economic groth in a developing country.To answer both questions a new unbalanced growth path hypothesis has been offered. Further, in this paper the utilization of the investment as a "strategic decision leverage" in the development of , alternatively, a developing nation' s economic production activities and transport service capability is also implied and suggested.

A two-channel ?-dependent n-α interaction potential is obtained by diagonalizing the corresponding Schrödinger equations by a similar transformation. The n-α elastic scattering cross section, expressed in terms of potential parameters, is fitted by low-energy scattering data.The results are compared with the previous results.

A double oscillatory potential which is found to be useful in modeling the problem of atomic rate transition is analysed by effective hamiltonian method. The result is the same as rigorous analysis. A back tunneling of the particle due to the accumulation effect on final local state must be taken into account in this double oscillatory case, suggesting that the golden rule of transition is a rough approximation and is not applicable to bound state tunneling.

From the result of item[1] in the list of references concerning the incermediate best quadrature formulas (in the sence of Sard) an explicit expression has been developed. The formula arises from a class of spline functions which will be obtained by some polynomials that may be regarded as generalizations of the even-degree Bernoulli polynomials.

The basic aim of this paper is to show that a specific sequence {Rn-3,n(z)}n=3 ∞ in the Padé table is bounded along the imaginary axis. Such a result can be applied to verify that {Rn-3,n(z)}n=3 ∞ converges uniformly to e^-z on the sector Sδ≡{z=reiθ:|θ|≦π/2-δ}

For a bound linear operator T on a Hilbert space let {T}', {T}'' and Alg T denote the commutant, the double commutant and the weakly closed algebra generated by T and 1, respectively. Assume that T is a completely non-unitary contrction with a scalar-valued characteristics function Ψ(λ). In this note we show that the condition that |Ψ(e^it)|=1 on a set of positive Lebseque measure implies that Alg T={T}'. Moreover, if Ψ(λ) is assumed to be outer, then these two conditions are equivalent. Our main result generalizes the well-known fact that the compressions of the shift satisfy Alg T={T}'.

The I-V characteristics of over 150 bulk InSb single crystals at 78°K have been measured. These samples 1mm*1mm in cross section and 0.4 to 13 mm in length, are of either the p- or n- type with carrier concentration ranging from 2.5*10^13 to 2.1*10^16 /cm^3. These multi-valued I-V characteristics were found to be highly non-linear, with as much as four distinct regions each of which can be attributed to a different transport mechanism. Furthermore, these characteristics were found to be dependent not only on the carrier type and doping density of the sample but also on the contact material (In or Sn) used. A theoretical explanation of the observed behavior will be presented.
