The use of the method of charaeterictics to solve super-critical flow problems has been previously established by several authors.In most cases,frictional resistance and bottom slope have been neglected.Taking into consideration the above two factors(Fig.1),the equation of continuity and the equations of motion are respectively (hu)_x+(h_v)_y=0.(1) uux+vu_y=g sin i-((g/2h))(h~2osi)_x-τu/ρhq.(2) uv_x+vv_y=-((g/2h))(h~2cos i)_y-τv/ρhq.(3) Where the subscripts denote the variables with respect to which partial...

The use of the method of charaeterictics to solve super-critical flow problems has been previously established by several authors.In most cases,frictional resistance and bottom slope have been neglected.Taking into consideration the above two factors(Fig.1),the equation of continuity and the equations of motion are respectively (hu)_x+(h_v)_y=0.(1) uux+vu_y=g sin i-((g/2h))(h~2osi)_x-τu/ρhq.(2) uv_x+vv_y=-((g/2h))(h~2cos i)_y-τv/ρhq.(3) Where the subscripts denote the variables with respect to which partial differentiations are made. Making use of the condition of irrotational flow v_x-u_y=O,(4) the energy equation can be obtained d((q~2/2))+gcosidh=gsinidx+(1/2)gh sin i·i_xdx-(τqdz)/(ρhu) =(gusini+(1/2)guh sin i·i_(τq)/(ρh))(dx/u).(5) The above are the fundamental equations for the type of flow discussed. It can be shown that the two systems of characteristics in the physical plane and the u v plane(Fig.2)are represented by C~+:dy~+=ξ~+dx~+.(21a) Γ~+ξ~-(dv~+)/(du~+-Gdx~+)=-1.(21b) and C~-:dy~-=ξ~-dx~-.(22a) Γ~-:ξ~+.(dv~-)/(du~-)-Gdx~-=-1.(22b) Where ξ~±=(15) G=(gu sin i+(1/2)guh sin i·i_x+(τq/ρh))/(u~2-ghcosi).(23) The superscripts + and- refer to the pertinent system of characteristics. For flat-bottom,frictionless channels,G=0;(21b)and(22b)indicate that at cor- responding points the tangents of C~+ and C~- are perpendicular to those of Γ~- and Γ~+ respectively and the Γ characteristics are systems of epicycloids. Taking into consideration the varying bottom slope along the x-direction and the bottom friction τ,it can be shown that the velocity vector still bissets the C characteristics(Fig.2) and both A~+ and A~- are given by q~2sin~2A=ghcosi.(20) With G different from zero,(21b)(22b)can no longer be integrated to give analytic forms and the angles between the tangents,φ~+ and φ~-,no longer equal to π/2.How- ever,based on these two equations,a graphical method is proposed,as illustrated in Fig. 6.

A study has been made on the effects of hydrostatic pressure at room temperature on peak currents IP, valley currents lv, peak voltages Vp, valley voltages Vv and the exponential excess currents Ix of several narrow GaAs P-N junctions. The pressure ranges from the atmospheric pressure up to 18000 Kg/cm2.

本文报导了在流体静压力18000kg/cm~2范围内,高简并砷化镓P-N结峯值电流lp,谷值电流lv,峯值电压Vp,谷值电压Vv,指数过剩电流Ix等参数随压力变化的实验结果。分析了峯值电压Vp随压力P的增加按指数规律显著减小,以及指数过剩电流Ix的斜率S =dlnIx/dv随压力P的增加而增加等实验结果。分析的结果指出:高掺杂砷化镓有效质量随压力的增加有较显著的增加,因此在考虑高简并砷化镓P-N结参数随压力变化的关系时,不能象在高简并锗P-N结样品中那样,只考虑禁带宽度Eg随压力的变化,而忽略有效质量随压力的变化。最后,本文对其他实验结果也作了简要的讨论。

Effects of hydrostatic pressure up to 18000 kg/cm2 on the current-voltage characteristics of germanium Esaki diodes are reported. The pressure dependence of the peak currents IP, valley currents Iv, peak voltages VP, valley voltages Vv, and the exponential excess currents Ix have been studied on sixteen germanium Esaki diodes. The results indicate that the semi-logarithmic plot of peak currents IP versus pressure P consists of two straight lines with different negative slopes. The intersecting point occurs in a pressure range from 5000 kg/cm2 to 9000 kg/cm2. The peak voltages VP change only slightly with pressure, while the valley voltages Vv are independent of pressure within the limit of experimental errors. For most diodes the pressure dependence of the valley currents is the same as that of peak current. The onsets of the exponential excess currents move toward high voltages with pressure. The pressure dependences of the peak currents and exponential currents have been discussed. It is shown that the presence of two straight lines with different slopes may be related to different tunnelling processes. A pressure coefficiant of the energy gap Eg can be determined at a constant exponential excess current; the result is in good agreement with that given by other authors.

本文报导了在流体静压力18000kg/cm~2的范围内,锗隧道二极管伏安特性随压力变化的实验结果。测量了十六只锗隧道二极管的峯值电流Ip、峯值电压Vp、谷值电流Iv、谷值电压Vv、指数过剩电流Ix和反向隧道电流等参数与流体静压力的关系。结果表明:峯值电流Ip相对于压力的半对数作图为斜率不同的二段下降直线,在5000—9000kg/cm~2范围内有转折点;峯值电压随压力改变较小;在误差范围内谷值电压不随压力而改变。对于大部分被测管子,谷值电流与压力的关系类似于峯值电流与压力的关系;随着压力的增加,指数过剩电流区向高偏压方向移动。讨论了峯值电流及指数过剩电流随压力变化的规律和其他结果。认为转折点的存在是表明隧道跃迁机构的改变;由指数过剩电流区固定电流值测偏压随压力改变,求得禁带宽度的压力系数与其他方法获得的结果很好符合。
