     Q is a block cipher as a candidate for NESSIE. In this paper Q is analyzed by linear cryptanalysis. The data complexity of the attack with 0.785 success rate is less than 2 118 , the storage complexity of the attack is less than 2 33 +2 19 +2 18 +2 12 +2 11 +2 10 . The result shows that Q is not immune to linear cryptanalysis.

     Besides, through another definition and method, we calculate the upper Minkowski content M*(d,E) and the lower Minkowski content M*(d,E) of Sierpinski gasket E respectively. That is, M*(d,E) ≈ 1.814 and M*(d,E) ≈ 1.811. Therefore we obtain that Sierpinski gasket is not Minkowski measurable by a new method.
     此外,本文又用另一种容度的定义和方法,具体求出了Sierpinski垫子E的上Minkowski容度M~*(d,E)和下Minkowski容度M(d,E),即:M~*(d,E)≈1.814和M_*(d,E)≈1.811.从而推出Sierpinski垫子的Minkowski容度是不存在的,用一种新的方法解决了它不是Minkowski可测的.

In this paper the general synthesis problem of optimal control systems with the criterion of transient responses as a positive integral functional (3) is discussed.In the first part it is assumed that the motion of controlled object is described by a system of ordinary differential equations and that the final states of the system form a bounded and closed convex region in n-dimentional euclidian phase space. A method is proposed for finding all optimal control functions which lead any starting state into the given final region of states. Some conclusions are obtained from the maximum principle by using transversal conditions of optimal trajectories in terminal points, and the particular properties of the stated problem are pointed out. The case of linear dif-ferential equations with integral quadratic functional criterion is investigated in detail.Further, in the second part the fundamental properties of isoloss regions, the rela-tions between the isoloss region and optimal control functions are indicated. As a direct result a partial differential equation determining the optimal loss-function J (x) is found and the connection between function J (x)and optimal vector control function u (x) is also stated. The methods proposed are practically the extension of the me-thods used by us for designing time optimal control systems as seen in [5, 6 ,7].Finally, an example is illustrated with optimal trajectories shown in phase plane.The necessary numerical data is calculated by an analog computer with high accuracy.

Emission and absorption band spectra of sulphur dioxide were studied in the region between 2600 to 2000 A.U. A new system of emission bands (about 150 bands) was found. When these bands were compared with the absorption bands and Mr. Lotmar's fluorescent bands, coincidences were found which amount to 40% and 50% of the total number of absorption and fluorescent bands respectively. These agreements and the very different structure as compared with the SO bands recorded on the same plate made it very probable...

Emission and absorption band spectra of sulphur dioxide were studied in the region between 2600 to 2000 A.U. A new system of emission bands (about 150 bands) was found. When these bands were compared with the absorption bands and Mr. Lotmar's fluorescent bands, coincidences were found which amount to 40% and 50% of the total number of absorption and fluorescent bands respectively. These agreements and the very different structure as compared with the SO bands recorded on the same plate made it very probable that SO2, is the emitter of these emission bands. Evidences were also found that these emission bands arc not the known bands of O2, Oa+ and S2 in the same region. As a further support a vibra-tional level scheme was worked out, using the three fundamental frequencies of the normal SO2, molecule (1150, 525, and 1360 cm-1) in the lower state and 750 and 350 cm-1 (possible also 1110 cm-1) as the frequencies in the upper state. This scheme accounts for 1Q% of the absorption bands, 70% of the emission bands and a small fraction of the fluorescent bands. While the scheme may not be the final due to the complexity of the vibrational formula, one feels fair, as far as the present evidence goes, to conclude that the emission bands observed are actually emitted by the SO2, molecules and that they can be fitted by a vibrational level scheme based on the three known fundamental frequencies of the normal state.

The effect of pressure on photographic sensitivity is discussed on the experimental basis that the quantity E/EC, where E is the illumination actually used when the photographic emulsion is under pressure, and Ee the illumination which would be required to produce the same optical density when the emulsion is under no pressure, is a function of pressure only and that for pressures greater than a certain value, E/Ee becomes a linear function of the pressure.

当照相时,照相片子——映像纸,软片,或玻璃板——被压,则其感光性减弱,是为照相的压力效应。设E为照相片子在压力P下得光密度d所需之光照度,若片子不受压力则用光照度E_e即可得此同一之光密度d,故E_e可称在压力P下E之有效照度。吾人实验证明E/E_e为压力P之函数,当p>200kg/cm~2时,E/E_e与P成正比例。 此照相的压力效应,与照相时所用光之颜色,极有关系。黄色光较绿色光为显,绿色光较蓝色光紫色光为显至紫外光则几无此效应。 又此效应之大小,随各种照相片子而不同。就我们所研究的蔡爱斯伊康正色软片,伊司门人像软片,和矮克发等色软片而论,以第一种为最大第二种次之第三种为最小。 这个效应,在实际上,或可有些应用。
