A method based upon simple diffraction theory is described for the calculation of modified paraboloid reflectors to produce from a point source a shaped beam of arbitrary shape in one plane and uniformly narrow in the perpendicular planes. A specific application of the shaped beam antennas is in connection with radar antennas designed for height finding. In this case the antenna must have a sharp elevation beam for obtaining precise elevation information and a rapid elevation scan. The beam must be relatively broad in azimuth in order that the target will be held in the beam long enough to obtain height information. If a fixed minimum of illumination is to be achieved at a given linear distance on both sides of the center line of the azimuth beam, the amplitude pattern must have the so-called "double cosecant" or "beavertail" shape.

本论文讨论如何利用简单衍射理论,计算改良抛物面反射器天线幅射之图型。此反射器可将一无方向性辐射源之能量聚集于任何形状之波束中。此原理可以应用在地面上或船面上寻求飞机高度雷达天线之设计。在此类雷达中,天线之方位图型必须为“双馀割平方”式;其特性为自波束对称轴线起,至其两端,辐射一次路程之功率,与方位角之馀割平方成正比。得此图型之最简易方法为置一狭窄之铅垂金属条于一截形抛物面反射器之中心,金属条之宽度,可改变波束之方向性;其支距,即金属条与反射器之距离,可影响两反射波之位相。故改变金属条之宽度及其支距,可得欲得之图型。 利用衍射及干涉理论,计算金属条及截形抛物面所生之总图型为:在方位面内,幅射强度J_H与水平角θ之关系为: J_H =AA[sin~2(15πsinθ)/(15πsinθ)~2-2(1-cosπ/4)sin(2πsinθ)/2πsinθ(sin(2πsinθ)/2πsinθ-sin(15πsinθ)/15πsinθ)]A为辐射波振幅,A为A之复共轭数。计算之结果与实验之结果,颇为一致。

1. On the basis of the preliminary studies from November, 1954 to March, 1955,further studies on the hibernation of mosquitoes were carried out in Changshafrom January to March, 1956. During this period tree holes, bamboo stumps, jars. earthern pots, fertilizer pits containing feces, basements, green-houses and mountaincaves were targets for the collection of hibernating mosquitoes each week. As aresult of this collection three species of mosquitoes hibernating during the winterwere newly discovered. Including the original four known species, Aedes albopictus,Aedes niveus, Culex fatigans, and Anopheles hyrcanus var. sinensis, which were foundin the preliminary study, there are seven in total representing five genera. 2. Aedes albopictus was confirmed to bibernate in the egg stage. Eggs werefound in earthern pots, jars, bamboo stumps of Phyllostachys mitis, tree holes ofLiquidambar formosana Hance, Evodic glauca Miq., Ilex purpurea var. oldhami Loes,Dalbergia sp., Albizzia kalkora Prain, Cinnamomum camphora Nees and Eberm. 3. Aedes niveus was again found to hibernate in the egg stage in the treeholes of Quercus sp., Quercus fabrei Hance, Quercus glauca Thunb, Ilex sp., Ilex pur-purea var. oldhami Loes, Liquidambar formosana Hance, Evodia officinalis Dode,Evodia glauca Miq., Spondias axillaris Roxb., Cinnamomum camphora Nees andEberm, Albizzia kalkora Prain, Hovenia dulcis Thunb, Dalbergia sp., Celtis sinensisPers, Ulmus parvifolia Jacq. 4. The larvae of second, third and fourth instars of Orthopodomyia anopheloideswere found in the tree holes of Liquidambar formosana Hance and Dalbergia sp.Whether Orthopodomyia anopheloides will actually hibernate in the larval stageneeds further observation for confirmation. 5. Armigeres obturbans was found to hibernate in the larval stage under thecover of grasses, leaves, twigs and so forth on the surface of water in fecal pits. 6. Culex hayashii was found to hibernate in the adult stage. Both male andfemale adults were caught in the mountain caves. The quantity of fat bodieswithin the female was noted and analysed. 7. Culex fatigans was again found to hibernate in the adult stage. Both maleand female adults were caught in tbe basements, greenhouses and mountain caves.But its chief shelter for hibernation was in mountain caves where the majority ofthis species was caught. Dissections showed that the quantity of fat bodies washigh for those adults which were caught in January and February while thosecaught in March showed a lower fat body content. After hibernation was over thefirst adults engorged with blood was caught on March 22nd. 8. The hibernation of Anopheles kyrcanus var. sinensis in adult stage was veri-fied. Female adults were caught chiefly in mountain caves. The condition of thewings, the development of ovaries as well as the quantity of fat bodies were notedand analyzed. After hibernation the first two females engorged with blood werecollected on March first. 9. The influence of temperature, humidity and light in the shelters where theadults of Culex hayashii, Culex fatigans and Ahopheles hyrcanus var. sinensis passedthe winter has been discussed.

Pseudosasa amabilis (McCl.) Keng f.,the Tonkin Cane,is a famous exported bamboo.The present paper deals with both variations in the mean fibre-lengths between the internodes and the distribution of fibre-lengths within the plant of three-year-old culm. All the macerated materials were selected from the outer part,i.e.,adjacent to the epidermis, the middle part and the inner part,respectively.These were taken from the middle of an inter- node along its diameter.Each part was consisted of two match-sized sticks,and was macerated and mounted on a slide.Total 615 slides were made.They were supplied from 205 internodes of 9 culms which had been collected from two slopes of the native place (Table 1).A report of the habitat of this Bamboo was quoted. The length of fibre was measured by projection with the aid of a graduated circular target (Fig.1;).All measurements and calculations were separated in regard to both different inter- nodes and parts. After studying the lengths of 24300 fibres which are distributed to the three parts from the Znd to the 19th internodes(Tables 2—5;Figs.2—3),some facts may be concluded as follows: 1)That the mean fibre-lengths between the internodes increase with the order of the internode upwards from the ground.When the fibre reaches its maximum length,it decreases its length with the internode order upwards further. According to the result of calculation,the increases of mean fibre-lengths of different parts from the 2nd to the 5th internodes generally are apparent.Before a given internode (i.e.,fibres of the outer part is at the 10th internode,those of the middle the 11th,and those of the inner the 13th),fibre-length tends to (or comparatively) increase wavely (or gradually).After this inter- node,the length tends to decrease,commonly wavely.However,fibre-length may slightly increase in the 17th internode.Beyond this internode,the length generally decreases apparendy.(Tables 2—3;Fig.2.) 2)That the increase or decrease of the length of an internode is similar to that of the fibre length,ie.,it varies with the order of the internode upwards.In other words,the increases of the internode lengths from the 2nd to the 5th internodes are correspondingly apparent.Next,the internode length gradually increases.After the 13th internode,the length decreases gradually. 3)That the variation in the fibre-length of the inner part comparatively is more similar to the variation in the length of the internode.This relation between fibre-length and internode-length seems not so closely as in the case of the fibre-length of the outer part,and,in terms,of the middle part.(Table 5.) 4)That the mean fibre-length of the outer part is longer than that of the middle and that of the inner.(i.e.,1995±25μ,1858±29μ,and 1687±27μ,respeetively.)Between the order of internodes,the increase or decrease of fibre-length of the outer part is more typical than the pheno- mena present in the middle and the inner parts (Fig.2). 5)That both variations in the diameter of an internode (here it is expressed as the diameter of the ring which taken from the lniddle of the internode) and in the thickness of the internode (here expressed as the wall thickness of the same ring) decrease with the order of the internode upwards.(Fig.2.) 6)That,therefore,the increase and decrease of the mean fibrelengths of different parts are affected by the factor of the internode length.And 7)That the distribution of fibre-lengths of three-year-old culm of Pseudosasa amabilis along the radii of the middle of the internodes examined,the fibres of the outer part are the longest,(1998± 445μ);those of the inner are the shortest,(1675±401μ);while those of the middle are the inter- mediate,(1851±409μ).(Table 4;Fig.3.)

青篱竹的三年生纤维长度的变化,从9条竹子(2个坡向,3个地形)的第2至第19节间的中央位置,分别以投影方法量度外部、中部和内部纤维,共计24300条,其结果概括如次:平均纤维长度系随节间顺序的上升而增加,当长度达相当程度时,则随节间顺序的上升而减少。节间长度的增加和下降,它和纤维长度一样,系随节间顺序的上升而变化。内部纤维长度的变化更类似于节间长度的变化。外部纤维的平均长度比中部的和内部的长些,至其中误差对中数的关系也较小。关于竹环直径和竹环壁厚的变化情形,是随节间顺序的上升而减少的。所以,不同部分的平均纤维长度的增加和减少,是受节间长度的影响的。最后,三年生青篱竹的纤维长度的分配,在节间中央的横切面上,外部纤维较长(1998±445微米),内部纤维较短(1675±401微米),而中部纤维则在二者之间(1851±409微米)。
