In this paper, we establish a lower bound as well as an upper bound for the error of the (n-μ,n)-th Padé approximant to e^-z. Moreover, we find a condition under which {Rn-μ,n(x)}n=1 ∞ can not converge geometrically to e^-z on [0,+∞).

We have built a simple, inexpensive, mechanical model of a finite Josephson junction consisting of a pendulum array along a rubber string, mounted on a metal frame. The pendulum array is driven at a constant torque by a gear connected with the string.This model has an equation of motion that is formally identical to the time-independent Josephson equation. We analyze the critical current Ic that can be carried by a Josephson junction as a function of an applied magnetic field. We find that the results are in excellent agreement with those calculated by Owen and Scalapino using a digital computer and with those observed by Matisoo in experiment, respectively.In addition, we have found that behavior of the Meissner effect and vortex structure in the junction barrier are easily demonstrated.In particular,the dynamics of the transistion between different vortex modes can also be investigated.We have made a detail analysis of it and try to provided a simple model for self-resonant modes with a bias voltage and a zero external magnetic field in Josephson junctions.

Baylis and Hushilt pointed out that the Lorentz-Dirac equation with the usual constraint(ẍμ(τ)→0 as τ→∞) for physical solution, may permit two or more solutions to some problems. We impose another constriant to make the physical solution unique.

本文介紹如何建立一數學模式來代表—製程在X管制圖管制下的製程收益。假設某些成本和風險係數為已知，則最佳X管制圖可以由解數學模式，使其損失成本為低時而求得。因為沒有解析法可以直接解析其數學模式而得最佳之X管制圖，本文又介紹一種數值法以解最佳之管制圖，並應用假設之成本和風險係數對最佳X管制圖做敏感度分析，以了解不同成本與風險係數對不同管制圖參數的影響。

A modified quasi-static model is developed to optimize the power efficiency of double-drift X-band Lo-Hi-Lo IMPATT diodes. We take the ionization rates and scattering-limited velocities for electrons and holes to be not equal at an operation temperature of 150 ℃, and let the carriers' ionization coefficient be in the form α=A*exp(-B/E),where E is the electric field.We maintain the carriers' velocities at saturation and solve for a steady state solution. All these assumptions not only save computer time, but also give us essential physical features.Current tuning effect is concluded as the most important factor in designing the device structure.Large signal values of negative conductance, susceptance,r.f. power generation efficiency are calculated as a function of the oscillation voltage amplitude for a specified bias current density. All of these informations would provide a useful guidance for both device and circuit designers.
一個新的字根加碼應用在鍵盤字根之定位

目前交大中文資料處理系統，所使用的中文鍵盤，在輸入字根序列之字根時，要同時操作兩個鍵—字根鍵(Data key)及選擇鍵(Select key)。本文將發表一個有系統的方法(Algorithm)。將字根適當的安排在鍵盤上時，只需操作字根鍵，不需使用選擇鍵即可單一的認別輸入的漢字。這個方法相信會將輸入的速率，適度的提高。本文選擇的漢字，是根據"中文電腦基本用字研究"中最常用的8532個漢字組成[1]。由於本文所發表的方法是由這些漢字綜合而來，其適用範圍將不止於此，足夠一般廣用之需要。

中文字根式輸入之簡化
(交大學刊編輯委員會, 1976-04)
許桂敏

K.M. Hsu
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。

The design and implementation of a Chinese FORTRAN System are presented.This Chinese FORTRAN System preserves the full capabilities of a FPRTRAN language with the added features of representing varisble name and data in Chinese and performing Chinese I/O operations. Besides,a Chinese tabulation language, CHITAL [1] has been incorporated into the Chinese FORTRAN System to enhance the capability of controlling output format of chinese data.A sample program and its running result are given in the end for reference.

The DEC-10 administrative system of National Chiao-Tung University is resulted by making an extension of the original system that is provided by the DEC-10 manufacture from the UFD basis into the SFD basis for meeting the special requirement of our computer center. This paper will present a detail description of this extension which consists of administrative control files, control file maintenance programs, administrative control programs, accounting process and failsaving programs. Some of them are resulted by making modification of the original system while the others by adding on.

The eigenvalue problem of a two-site Hubbard Hamiltonian, which contains sboth the correlation term U and the hopping term t , is solved exactly and the grand partition function of the system is obtained. The chemical potential as a function of temperature for a given number of electrons per site n is numerically calculated for several values of n.The chemical potential as a function of n at absolute zero is shown to have three discontinuouties at n=1/2,1,and 3/2. The magnetic suspectibility per site is shown to be of the Curie-Weiss form for the temperature range t<
