In this paper a new method has been proposed for computing the potential functions of internal rotations.Applying this method,we have calculated the potential functions of several important molecules,such as 1,2-dichloroethane, 1,1,2-trichloroethane,1,1,2,2-tetrachloroethane,n-butane,2-methyl butane,2,3- dimethyl butane,etc.All the calculated results agree with the experimental data. According to our theory,the potential functions of the three types of molecules CX_2Y-CX_2Y,CXY_2-CXY_2 and CX_2Y-CXY_2 are intimately related,if the poten- tial function of the first molecule is written as V_1(φ)=A_1+Bcosφ+Ccos2φ+D_1cos3φ. Then those of the second and the third will be of the following forms: V_2(φ)=A_2+Bcosφ+Ccos2φ+D_2cos3φ V_3(φ)=A_3-Bcosφ-Ccos2φ+D_3cos3φ where D_i~'s(i=1,2,3)can be calculated from the potential barriers of CX_3-CX_3, CY_3-CY_3,CX_3-CY_3 or similar kinds of molecules,while the A_i~'s are not important for actual problems. In this paper we have also discussed the structures of hydrazine,ethyl alco- hol,hydrogen peroxide,and the meso and active forms of the CXYZ-CXYZ type of molecules.Besides,we have pointed out that the potential functions of both the meso and the active forms of the CXYZ-CXYZ type can be calculated from those of the CX_2Y-CX_2Y,CY_2Z-CY_2Z and CZ_2X-CZ_2X types.

Twin formation associated with grain boundary migration in recrystallized armcoiron has been studied by the method of vacuum etching.No noticable substructureswere observed after recrystallization at 750℃ for 5 hours.However,after reheatingfor a short time at 770℃,fine substructures appeared in most of the ferrite grains.During prolonged heating the substructure-free grains gradually grew at the expense ofthose possessing substructures.When the reheating temperature is raised close to theA_3 temperature,grain boundary migration is markedly accelerated.Two types of twins were observed during grain growth.One of them,probablyidentical in nature with ordinary annealing twins,has its non-coherent twin boundaryalways attached to the old grain boundary.Depending on the manner of migrationof the grain boundary and the non-coherent twin boundary,such type of twins maygrow,retreat,or even disappear.The other type of twins has a characteristic wedge-shaped twin boundary which is quite stable,and little change has been observed afterprolonged heating.

应用真空热侵蚀方法,研究Armco铁晶粒长大晶界迁移过程中,退火孪晶形成的过程。观察到在低于A_3点退火后,在了770℃短时间保温,多数α-铁素体晶粒内出现细小亚结构。随着加热时间的延长,具有细小亚结构的晶粒逐渐消失,原先不含亚结构的晶粒,则逐渐长大。将加热温度提高至A_3点附近,显著加速晶界迁移的过程。在长大的晶粒中,出现两类退火孪晶。一类的性质与一般退火孪晶相似,似其非共格孪晶界经常出现于旧晶界附近。视晶粒间界与非共格孪晶界迁移的情况,这类退火孪晶在保温过程中,可能随晶界迁移而伸长,亦可能随非共格孪晶界迁移而变细或消失。另一类孪晶的特点是一端在晶粒间界上,另一端呈楔状。楔状孪晶界很稳定,在保温过程中,未发现任何变化,在晶粒间界上的一端,则与晶粒间界一起,发生迁移。根据观察结果,认为α-铁中退火孪晶形成的机构与Burke及Furnbull所提出的面心立方金属中退火孪晶形成的机构相似,退火孪晶的形成与晶粒间界迁移有密切关系。

This paper is to discuss the properties of high order aberrations taking advantage of as much as possible of using the methods of approximation. The number of independent terms of secondary aberrations is first accessed and its geometrical significance ascertained. By a coordinate transformation the effects of the change of stop position on aberration coefficients are determined. The relations between the position of the object and its aberration coefficients are found on the basis of Fermat principle, by regarding each ray as emitting from different object points lying along this ray.

本文的主要目的在以近似方法讨论高级象差特性。首先由对称性讨论了二级象差的独立象差数,近似讨论了象差的几何意义,再由坐标变换的观点导出了光栏移动时象差变化的规律。由Fermat原理和同一光线可看作是各不同点发出的观点导出了物体移动时象差变化的规律。由于运用Fermat原理,所得的结果实际上是略去初级象差影响后的近似结果,因此表示式相当简单。 然后我们把象差产生的原因分为二类。其一称作是本徵的,是入射光束无象差时必然产生的象差,用象差看作球差的观点导出了它们的表示式,结果表明,高级球差和本徵轴外球差是象差产生的原因,并导出了各种象差同时产生的状况。象差的另一类称作是衍生的,它们是由入射光线原有象差引起的初级象差差异,由初级象差理论即可得出它们的表示式。这一些高级象差的规律和近似表示可作为评断象差产生原因的半定量依据。 最后,用Fermat原理讨论了高级色差问题,并说明Fermat原理之所以可在高级象差理论中应用的理由及不致误差过大的应用范围。
