An equation of the Bethe-Salpeter type is used to obtain the internal wave function of mesons. It is found that if the potential well between the straton and anti-straton is of the pseudo-scalar type, then the 0- and 1- mesons will satisfy the same approximate radial wave function, and thus lead to SU8 symmetry. We have shown previously that pseudo-scalar potential is the only single type of potential which leads to this symmetry. The potential is V = V0 + V1, where V0 represents a super-strong deep well, the...

An equation of the Bethe-Salpeter type is used to obtain the internal wave function of mesons. It is found that if the potential well between the straton and anti-straton is of the pseudo-scalar type, then the 0- and 1- mesons will satisfy the same approximate radial wave function, and thus lead to SU8 symmetry. We have shown previously that pseudo-scalar potential is the only single type of potential which leads to this symmetry. The potential is V = V0 + V1, where V0 represents a super-strong deep well, the effect of which is to reduce the very large mass M of the free straton to a small effective value. The motion of the straton inside the meson is therefore relativistic. V1 represents a small potential of the order of 1/M of a simple harmonic oscillator. A tensor force is also introduced to account for the splitting of energy levels of the states with the same spin and orbital angular momentum. Our solutions for the ground and angular excited states of 0- and 1- mesons practically explain all the observed meson states. Our theory can apply equally to the baryon states if the phenomenological potential V0 is reduced by a factor of 2.

本文利用Bethe-Salpeter型的方程处理了层子模型中的介子内部波函数,指出如果层子和反层子之间的作用可以用一个赝标型位阱来代表,那么0~-和1~-介子将满足相同的近似迳向波动方程,从而导致SU_6对称性。我们以前曾经证明赝标型位阱是唯一可以导致这个对称性的单一型位阱。我们的位阱是V=V_0+V_1,V_0代表一个超强的深位阱,它的作用是降低层子的原始质量M,使它的有效值M′变得很小,使得层子在强子内部的运动是相对论的。V_1代表数量级为1/M的简谐振子位阱,另外还引入一个张量力来解释自旋和轨道角动量相同态的能级分裂。我们得出基态和角动量激发态0~-和1~-介子的解,基本上解释了所有观察到的介子。我们的理论可以同样处理重子态,只要唯象位阱V_0只有介子的值的一半。

Making some assumptions, the angular momenta J of 183 galaxies are calculated from V_m and r_m The relation J∝M~(1.66) is obtained.

The masses of 213 galaxies are statistically analyzed, 175 of which are radio masses, 38 optical masses. Making some assumptions, the angular momenta J of 183 galaxies are calculated from V_m and r_m The relation J∝M~(1.66) is obtained. The galaxies are classified acoording to their mass values as supergiants (5×10~(11)-10~(13)M_⊙), giants (10~10—5×10~(11)M_⊙), intermediate mass galaxies (10~5-10~10M_⊙), and dwarfs (10~5-10~8M~⊙). E type galaxies have the biggest mass range, there are many E supergiants and dwarfs. S type supergiants are very few, and there are no S dwarfs. Galaxies with large mass also have large angular momentum, and so disintegrate more easily, forming double or multiple galaxies. Galaxies with large mass have massive nuclei, which are apt to generate violent activities, destroying the spiral arms. Galaxies with small mass have low angular momentum, so are unable to flatten into disk galaxies, unable to prevent gas from forming stars. Without a disk and gas, there would not be spiral arms. From SO to the various subtypes of S, to Ir, the mean values of M J, and angular momentum density j, all increase to maximum at Sb, and then decrease. Dividing J by M~(7/4) to eliminate the influence of M, the “normalized” angular momentum J/M~(7/4) does not increase as the type gets later; but SB galaxies have larger J/M(7/14) values than SA, indicating that galaxies with large angular momentum have higher probability to become bar-spirals. k = V_m~2/r_m is the centrifugal force per unit mass at r_m Its mean value also reaches maximum at Sb, and then decreases.

本工作对213个星系的质量和角动量值进行了分析。175个质量值是射电方法得出的,其余38个由光学方法得出。由星系的极大自转速度V_m及其相应处的半径r_m 计算了183个盘星系的角动量J,得到了关系式J∝M~(1.66)。本文按质量值把星系分为超巨系(5×10~(11)—10~(13)M_⊙、巨系(10~(10)—5×10~(10)M_⊙)、中系(10~3—10(10)M_⊙和矮系(10~3—10~3M_⊙)。E型星系的质量范围最大,其中矮系和超巨系都最多。S型星系超巨系很少,矮系也没有。对此,本文进行了讨论。从S0到S系的各个次型到Ir型星系,星系质量M、角动量J和角动量密度j的平均值都是先增加到Sb型达极大值,然后减少。以M~(7/4)除J,以消除M的影响,剩余角动量J/M~(7/4)也不随类型变晚而增大。但SB系的J/M~(7/4)值却比SA系大,表示角动量大的星系较可能成为棒旋星系。 r_m处单位质量的惯性离心力k-V_m~2/r_m的平均值也是Sb处极大,Sb以后减小。本工作为进一步研究星系形态分类的演化意义提供了资料。

There are significant differences in cold tolerance between the Xian type varieties "Qing-Yang-2", "Guang-Lu-Ai-4" and "Gui-Chao-2", the sequence of to lerance as."Qing-Yang-2">"Guang-Lu-Ai-4''>"Cu?Chao-2'.After the cold injury under the natural conditions, the leaves of rice seedlings changed from green to white, but after the rice seedlings were transported into the normal growing temperature conditions, th?leaves were changed from white to green.During these processes, stronger cold-tolerance varieties(such as "Qing-Yang-2"and"Guang-Lu-Ai-4'')recovered, their growth more speedly, and more vigorously. The obvious changes were showed in the submicroscopic structures of their leaf cells : occured changes in orientation of the chloroplast lamells arrangement, .appeared unclear and slight vacuoles inside the chloroplast, and its outside cover-membrance, however, is intact. The unclear chromatin was coagulated into a larger mass, and the nuclear membrance still remained their integrality. These changes are reversed.The low cold-toleranceness varieties(such as "Gui-Chao-2")due to the temperature too low,or the low temperature last too long,the microscopic structures of leaf cells, especially the memprance structures weres subjected by serious destruction,the chloraplasts were decomposed, large amount of vacuoles were appeared even more to form several huge vacancies.These changes are unreversed,and often resulted in the leaf wilted then the plant death. Besides, there were acumulated dense mass in the intercellular layers between various cells of the mormal leaves. The active matter exchanges took place in the two neighbour cells through the plasmodesmi,but after treatment of the low temperature,this phenomenon disappeared immedially.

对籼稻品种庆元2号、广陆矮4号和桂朝2号作人工低温处理和自然低温鉴定。试验结果;庆元2号苗期耐寒性最强;广陆矮4号次之;桂朝2号耐寒性较差。同时,分别对叶片细胞亚显微结构进行观察。经自然低温冷害后,叶片由绿变白,但恢复正常生长的温度后,叶片又由白逐渐转绿。在这个过程中,耐寒性较强的品种(庆元2号和广陆矮4号)恢复生长较快,恢复能力较强。其叶片细胞亚显微结构表现出明显的变化:叶绿体片层排列方向发生改变,叶绿体内出现轻度空泡,但叶绿体的外部被膜仍保持完整,细胞核的染色质凝集成较大的质块,但均匀分散,核膜仍保持完整,这些变化是可逆的;不耐寒的品种(桂朝2号)或低温过低,或低温持续时间过长,叶片细胞的细微结构严重被破坏,尤其膜结构受破坏,叶绿体大量解体,出现大量空泡,这些变化是不可逆的,往往导致叶片桔黄,植株死亡。另外,在正常叶片中,可见细胞与细胞之间的胞间层积聚着浓密物质,两个细胞通过胞间连丝在进行物质交换,经低温处理后,胞间连丝即行消失。
