Both sectorphotometer and microphotometer analyses were carried out on the Hg spectrum transmitted by papers popularly used as window materials in Chinese homes. The intensity distribution of transmitted radiation, after normal incidence, through samples of nine different kinds of paper have been studied, and the total transmission calculated for various wavelengths.

以水银灯为光源,正射於纸上,其透射部份,用分光摄影法定量。以分圆光度计(Sectorphotometer)及显微光度计(microphotometer)量出九种窗户纸之紫外线透射性。并实验各种纸之抗断强度及其纤维之构造等,俾得相当之评价。 通常窗户纸对於具有最高生理效用之紫外线(波长2967A.U.)之透射量可居百分之十九至四十一;我国南部之壳片窗亦可透射百分之二十。至於玻璃窗,其透射量则等於零。外国虽有特备之玻璃能透射百分之二十至八十之此种紫外线,但其价值殊昂,不能使其遍普应用,可见两者反不若我国之窗户纸为佳矣。 窗户纸中以平粉连纸透紫外线最多,如将纸上桐油,则可视线及紫外线之透射力,皆有可观之增加,同时亦可去潮湿以致易破之影响。倘以普通之豆油油之,则其易於变黄,并减低其紫外线透射力,甚不适宜也。 如欲得较完全之讨论,请参考陈尚义之硕士论文,现存於燕京大学图书馆。

1)The sound-conducting apparatus in the middle-ear of domestic fowls includes the membrana tympani,columella,musculus tensor tympani and several ligaments.These or- gans possess a simpler structure than in mammals,and yet their peculiar structures and interconnections between them make it possible to accomplish the conduction of sound waves. 2)The membrana tympani is about 6mm in diameter and forms the dorso- medial wall of the medial end of the external acoustic meatus.The surface of the mem- brane slopes ventro-medially,with...

1)The sound-conducting apparatus in the middle-ear of domestic fowls includes the membrana tympani,columella,musculus tensor tympani and several ligaments.These or- gans possess a simpler structure than in mammals,and yet their peculiar structures and interconnections between them make it possible to accomplish the conduction of sound waves. 2)The membrana tympani is about 6mm in diameter and forms the dorso- medial wall of the medial end of the external acoustic meatus.The surface of the mem- brane slopes ventro-medially,with the lateral end of the columella attached to its caudo- medial region.The tendon of the tensor muscle is inserted on its lateral surface and pushes its central part outward,producing a concavity of its inner surface. 3)The tensor muscle arises from the ventro-lateral part of the foramen magnum of the occipital bone and ends in a delicate tendon inserting on the lateral surface of the drum membrane where the extracolumella is attached.When the muscle contracts,it draws the drum outward and tenses the membrane,therefore it is better named as tensor tympani externum. 4)The columella,with its shaft directing in an oblique direction,has two special functional characteristics:(a)When the tensor tympani retracts the membrane,the columella changes its oblique angle to compensate the variation in the distance between the drum and the fenestra vestibuli;(b)The oblique position of the columella diminishes the force of the sound waves(push and pull)and avoids damaging the drum membrane. 5)The inner surface of the membrane tympani is concave,and therefrom the ten- sor tympani internum has lost its functional significance to regulate the tension of the drum,and has degenerated into a ligament.This ligament is divided into medial and lateral parts;the medial part is stronger then the lateral. 6)The ligaments of membrana tympani are the drum-tubal and marginal.Liga- ments of the columella are the columello-squamosal and ligament proprium.The columello-squamosal ligament is the most important apparatus to fix the columella,and the crucial point between the columella and ligament is the hinge of the columella move- ment.

1.鸭的中耳传声器官主要包括:鼓膜、听骨、张肌及韧带四部分。结构比较简单。它所以能完成传声过程中一系列的复杂动作,主要靠每一组成部分的特殊结构和各部使之间的连接。2.鼓膜北京鸭的鼓膜直径约6毫米,构成外耳道内端的背侧壁。鼓膜面自后,外,上方向前、内、下方倾斜。柱状听骨的外端附着在鼓膜的后内下区,占全鼓膜面的1/4—1/3。听骨中脚前端附着部约位于鼓膜中央。该部又为鼓膜外张肌的附着部。3.鼓膜外张肌鼓膜外张肌自枕骨项面的枕骨大孔下部两侧起始。肌腹成半环形,前端腱纤维混入鼓膜的听骨附着区。张肌收缩时,向外开张鼓膜,以调整膜的紧张度。4.鸭的听骨采取斜位,在传声过程中有三个优点 (1)当张肌收缩或弛缓时,听骨可借本身斜度的改变,在保持听骨两端位置不变的情况下,来调整鼓膜与前庭窗之间的距离,保持内耳的压力不发生大的变化;(2)鼓膜振动时可以借听骨斜度的改变,使内耳的压力发生变化;(3)前庭窗可以免受听骨垂直向的正面冲击,特别是在声音有较大的突然变化时,由于力的方向改变,在一定程度上可以保证内耳不致遭受破坏。5.家禽鼓膜外张肌的名称问题鸭与鸡以及一般鸟类的鼓膜张肌,根据它所在位置和力的作用方向,应称之为鼓膜外张肌。相当...

The photoelectric astrolabe type I was made in China in 1971;and several improved photoelectric astrolabes,of a second model,were constructed from 1972 to 1974.The principles and a description of the main parts of the new instruments are as follows : (1)By means of a fused quartz mirror system and mercury horizon(shown in fig.4),a telescope with a fixed glass grid,three photomultipliers with respective a.c.amplifiers and a time recorder,the astrolabe can determine the time of almu- cantar transit of a star without...

The photoelectric astrolabe type I was made in China in 1971;and several improved photoelectric astrolabes,of a second model,were constructed from 1972 to 1974.The principles and a description of the main parts of the new instruments are as follows : (1)By means of a fused quartz mirror system and mercury horizon(shown in fig.4),a telescope with a fixed glass grid,three photomultipliers with respective a.c.amplifiers and a time recorder,the astrolabe can determine the time of almu- cantar transit of a star without personal error. (2)The evacuated Ritchey-Chrétien telescope has an aperture of 20 cm and a focal length of 2.4 m. (3)As is expected,the vacuum telescope tube with horizontal entrance window is able to eliminate astronomical refraction,the dependence of refraction on the spectral class of the star and irregular refraction in the tube.Besides,the vacuum tube provides a stable environment for optical system,especially for mercury horizon. (4)The astrolabe is equipped with high and low speed motors,as well as an automatic tracking mechanism in azimuth direction. (5)In order to reduce the heat influence from the surroundings,the astrolabe is set on the first floor of the observing building,whereas the control console,elec- tronic equipments and the operator are on the ground floor. At Shanghai Observatory,observations have been carried out with the new instrument since Sep.1974.The excellent results obtained will be published later on.

我国于1972年制成Ⅰ型光电等高仪,1974年又制成Ⅱ型光电等高仪.新仪器的特点如下:(1)借助熔石英角镜组和汞地平、一架望远镜和固定的玻璃记录栅、三个光电倍增管及其交流放大器和一架计时仪,此仪器能无人差地测定星过等高圈时刻.(2)真空的 R-C 望远镜的口径为20厘米,焦距2.4米.(3)有水平入射窗的真空镜筒能消除天文折射、大气色散及镜筒内的反常折射.真空镜筒还为光学系统及汞面提供了一个稳定的环境.(4)此仪器设有快、慢传动电机和自动方位跟踪机构.(5)为消除周围物体的热影响,此仪器安放在观测室楼上,而控制台、电器设备和操作者都在楼下.自1974年10月起,此仪器已在上海天文台进行了常规观测.获得的优良观测结果将在以后发表.
