In this paper, a technique is proposed in order to study triple time series.


However, the triple timetemperatureinterfacial area equivalence principle could not be verified, in this instance, since the interfacial area between sulfur, the new filler, and bitumen could not be established.


Currently, a number of different new concepts of CyATDM, including approaches such as single, double or triple timepoint and abbreviated AUC determinations, have been introduced.


So in essence we'd have to introduce what actually amounts to a Triple time format into our model.




 Spectroheliographic scanning (i.e. Spectroheliogram) is an interesting effective observational means. The photography has been adopted for local regions of the Solar disc on the Na line (NaID25890A) of a 40cm horizontal spectrogaph of Yunnan Observatory.The basic principle is that the camera in the line focal plane of the spectrograph should make the stable homogeneous synchronous movement in the same direction as the solar image in the telescope focal plane (i. e. the incident slit plane). Therefore, a spectroheliograph,... Spectroheliographic scanning (i.e. Spectroheliogram) is an interesting effective observational means. The photography has been adopted for local regions of the Solar disc on the Na line (NaID25890A) of a 40cm horizontal spectrogaph of Yunnan Observatory.The basic principle is that the camera in the line focal plane of the spectrograph should make the stable homogeneous synchronous movement in the same direction as the solar image in the telescope focal plane (i. e. the incident slit plane). Therefore, a spectroheliograph, which is used to control the movement of the camera, by the mechanical speed changes of a synchronous motor, is used to substitute for the original photographic device of Na bands. The slit of the spectroheliograph is aligned with the line core of D2 and move in the line dispersion direction. The micrometer screw, which is located on the mirror mounting in front of the incident slit of the spectrograph and enables the mirror to turn round the vertical center, is driven by a stepping motor so that the solar image can make transverse movement perpendicular to the optical axis. The stepping motor works in double tripletime and the circuit consists of a pulser, a commutator distributar and a power amplifier. The whole control unit enables the solar image and the camera to move syschronously in the same direction.The test indicates that the instrument is in better state (the parameters are stable and the synchronous performance is better). Under the mesoclimate conditions, in the active region data obtained the distinguishable details may be at least 4"5" and the inhomogeneous structure surrounding the active region can be resolved.  本文简介了太阳金属钠(NaID_25890A)线光谱单色像的仪器装置和试验结果。  In this paper, a singular perturbation method is applied to solve the intercept problems of aeroplanes in the horizontal plane within intermediate and long ranges.

In this paper, a singular perturbation method is applied to solve the intercept problems of aeroplanes in the horizontal plane within intermediate and long ranges. It begins with the introduction of the general methods of flight paths' optimization, then the mathematical model of the singular perturbation is set up by using the separation method of triple timeyardsticks. The outer solution,the boundary solution and the noncondition combinatorial solution are obtained,and the optimal control laws of the interception in the minimum time is reduced with the thrust parameters and the roll angles as their control variables. The paper takes the F4 aircraft as an example,the minimum time and the optimal flight path for successful intercept are calculated. The result may supply a reference to the.realtime and online optimal intercept problems.  本文应用奇异摄动法探讨水平面内飞机的中远程拦截问题。在介绍航迹优化的一般方法之后,通过采用三重时间尺度分离法建立奇异摄动的数学模型,求出了外层解、边界层解和一致有效的组合解,导出了以推力参数和滚转角为控制变量的最短时间拦截的最优控制律。并以F4飞机为例,计算了拦截成功的最短时间和最优航迹。其结果可作为空中拦截实时在线优化的参考。  Let dX(t)=σ(X(t))dB(t)+β(X(t)dt be a ddimensional nondegenerate diffusion processes.It is proved that(i)if d=3,then there are no 4 triple time set and 4 triple points set for X(t),a.s.(ii) if d=4,then there are no 3 triple time set and 3 triple points set for X(t),a.s.(iii) if d≥5,then there are no 2 triple time set and 2 triple points set for X(t),a.s.  设dX(t)=σ(X(t))dB(t)+β(X(t))dt为一非退化d(d≥3)维扩散过程.证明了:(i)3维非退化扩散过程没有4重时集和4重点集;(ii)4维非退化扩散过程没有3重时集和3重点集;(iii)5维以上的非退化扩散过程没有2重时集和2重点集.
