This paper is a description based on the Sinanthropus materials including5 teeth and two fragments of humerus and tibia recovered since the restorationof the Choukoutien excavation in 1949.The teeth of Sinanthropus are much bigger than those of modern man.Theleft medial upper incisor bears well-developed basal tubercle on the lingualsurface.The upper first and second premolars are robust in size and theirchewing surfaces are covered with wrinkles of special patterns.The crowns ofthe first and second lower molars are characterized by their lowness in relationto their lengths and breadths.Pronounced cingulum is present on the buccalsurface of the crown.The humeral shaft is almost identical with that of modern man.Thetibial shaft is slender and its anterior border is blunt.The walls of the tibiaare extraordinarily thick and its medullary cavity is very narrow.The results of the study of Sinanthropus pekinensis by the present authorsand others clearly show that the upper extremity bones of Sinanthropus arealmost identical with those of modern man;the lower extremity bones are definitely human in form and appearance,but possess also some primitive cha-racters.The teeth and skulls possess many primitive features.The cranialcapacity is considerably smaller than that of recent man.It is due to labour,and the operations of the hands that the upper extremity is differentated fromthe lower one.The differentiation of the extremities is followed by the deve-lopment of the brain and the brain case.These results further enrich Engels'theory of the transition from ape to man and testify to the truth that“labour(?)eated man himself”.

A collection of blood flukes of cattle and sheep was obtained from such districts as Yin Chuan (银川) Ping Lo (平罗), Ling Wu (灵武), Chiu Chuan (酒泉) and Min Hsian (岷县) of Kansu Province.Upon morphological studies, the parasites were identified to be: 1.Ornithobilharzia turkestardca (Skrjabin, 1913) Price, 1929. 2.O.turkestanica var.tuberculata Bhalerao, 1932, 3.O.cheni nov.sp., and 4.O.bomfordi (Montgomery, 1906). Ornithobilharzia cheni, described herein as a new species can be easily differentiated from its most closely related form, O.turkestardca (Skrjabin, 1913) Price, 1929 by the following salient features: (1) The testes of the present species are larger and arranged as a crowded and overlapped single row, whereas those of the Soviet species are smaller and generally arranged as an irregular, double row.(2) The cuticle of the present species is tuberculated, whereas that of the Soviet form is smooth.(3) The male speeimens of the present species are stained bluish violet (i.e, principally violet), but the female, dark brown; whereas both the male and the female specimens of the Skrjabin's flukes are stained purplish blue (i.e., principally blue).The color reaction based on the different biochemical properties of the two species, is rather certain, provided the same staining conditions are maintained. A key for the identification of the above mentioned four Ornithobilharzia species is appended.

The effects of roll pass design on the mechanical properties of rails and the changes in

文中详细分析了目前孔型设计对于钢轨质量的影响的各种因素和存在的问题,并对于帽形孔中切入楔子的深度和角度进行了比较细致的研究。此外在钢轨轧制过程中每一道次机械性能的变化作了全面的比较分析并探讨了产生这些变化的原因。结果指出了: 1.在帽形孔中切入楔子的深度和角度的变化,对轨底的机械性能影响不大,因此可以采用比较矮而的楔子。此外不均匀变形对成品性能的影响亦不大,因此采用2个或4个帽形孔主要决定于设备条件和生产情况。2.随着轧制道次的增加,轧件性能有很大的变化。在第二孔或第三孔轧制后,轧件的机械性能有下降的现象,但第六孔以后,轧件的性能则变化很小。较快冷却情况下,加工温度对成品的机械性能影响不大,因此可以考虑提高加工温度、加工量和轧制速度,从而把孔型数目减少。
