In the summer half year,the average intensity of the Pacific high pressurechanges more or less abruptly.It strongly increaseses from June to July and de-creases gradually from April to June.In middle September it decreasees suddenly. In.the summer season(from June to August),tha advance and retreat of theWestern Pacific pressure ridge(moving from east to west or reversed)is intimatelycorrelated with teh upper westerlies.At the same time,the Pacific High itselfis an important factor of the atmospheric circulation.When the zonal circulationis strong,the intensity of the Pacific High is also relatively strong and the posi-tion of the western Pacific pressure ridge changes little.When the small wavesin the westerlies move out from Asia into the Pacific Ocean,the position ofthe western Pacific pressure ridge only vibrates slightly.But,when the waves in thewesternlies are strong,the western Pacific pressure ridge advances westward andthen retreats eastward apparently.The period advance and retreat of the ridgeis about five or six days During the period of fow zonal circulation index, thewestern Pacific pressure ridge moves eastward.when the circulation index growsfrom low to high,the ridge advances westward.The range of longitudes ofoscillation of the ridge in this type is largest,about 30-40 degrees,and the periodof oscillation is longest,about half month in general.The longest period reachesone month. Besides,the movement of the Pacific High ridge is also studied in relationto he tropical systems,such as typhoons.

夏半年太平洋高压的平均变化,带著突变性质的增强和减弱,突然的增强发生6月到7月,而4月至6月更有逐渐减弱的趋向,到9月中旬以後则突然的减退。 夏季西太平洋高压脊的东西进退和整个西风环流变化及西风环流的情况密切关连,同时太平洋高压本身也是西风环流及其变化的重要因素之一。当西风环流强时,太平洋高压比较强大,这时太平洋高压脊的变化很少,在西风环流小波动东移的过程中,太平洋高压脊只有微小的摆动。但西风带波动较大时,随着西风槽和高压脊的东移,太平洋高压脊便有了比较长时期的和明显的东退和西伸,它的周期一般都在5、6天左右。如果西风环流起了大型的变化,即西风环流由强转弱,再由弱转强,太平洋高压脊随之不断的东退和西伸,进退的范围可达30-40经距。它的周期较长,一般都在半个月的光景,最长的可达一个月,10天以内的很少。 太平洋高压脊除了和西风带的环流,极地高压和低压槽有关外,也和它南边的气压系统,如台风和热带风暴有关。

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”.

1.本文系根据1949年北京解放后迄今在周口店中国猿人化石产地发掘而得的及由过去发现的碎骨中清理而得的中国猿人化石,加以研究,计有单独的牙齿5枚(左上内侧用齿,右上第一及第二前臼齿,左下第一和第二臼哲各1枚),肱骨及胫骨干各一小段,而胫骨化石是在周口店首次发现的新材料。2.中国猿人的牙齿有大小两种头型,大型为男性,小型为女性,本标本中的上门齿,下第一及第二臼齿属大型,所以是男性的,上第一及第二前臼齿属小型,所以是女性的。3.中国猿人的牙齿,无论其齿冠或齿根,都远较现代人或尼安德特人为硕大和粗壮。4.上内侧门齿齿冠舌面的基部有很发达的底结节及由其延伸而来的指状突, 舌面两侧增厚且向内捲而使舌面成为铲形?莞氤莨诘某ぶ嵩谝恢毕呱隙蝗缦执说某莞氤莨诘某ぶ岢梢欢劢恰?.上第一前臼齿的齿冠和齿根都大而粗壮。齿冠的唇面有三角形隆起,但其尖端偏向前方。唇结节较舌结节为大和高,嚼面的唇半大于舌半,具有特殊型式的纹理。齿根极宽,部分分为唇舌两枝。6.上第二前臼齿稍较上第一前臼齿为小,舌结节不如第一前臼齿的倾向前方。唇舌两正中(?)互相连续而将嚼面分为前后两半。唇舌两结节的大小和高度约等。齿冠唇面三角形隆起的尖端并不偏向前方而在正中位置。齿根仅在尖端分为唇舌两枝。7.下第一及第二两臼齿大小相似。齿冠硕大,但其高度若与其长度和宽度相比,则相对极为低矮。齿冠唇面有明显的扣带,两臼齿全属五结节齿型,以前内结节为最高和最大。齿根极为粗壮,分为前后两枝,前枝较短而直,后枝则较长而明显向后倾斜。前枝末端分叉,后枝末端则为单独一尖端。8.肱骨干完全具有现代人的形式,唯一真正与现代人的不同之点在共髓腔较小和骨壁较厚,此外其三角肌粗隆特别发达。9.胫骨细长,前缘较为圆钝,中段的横切面呈圆钝的三稜形。胫骨干中央大部为海棉骨质所填充,髓腔极小。中国猿人的胫骨较苏鲁人稍细,但两者颇为相似。10.过去及本文对于中国猿人化石研究的结果,明显指出中国猿人的上肢骨与现代人极为相似;下肢骨虽已具有现代人的形式,但又有若干明显的原始性质;而牙齿及过去发现的头骨,则远较现代人为原始,脑量也远在现代人之下,说明了最初是由于劳动,由于手的使用而使手足发生了分化,脑子随着发展了起来,头骨和牙齿的形态发生了改变,这种结果进一步充实了恩格斯从猿到人的理论,阐明了“劳动创造人类”的真谛。

Integrating with respect to time the equation for the balance of angular momentum of the atmosphere north of certain latitude (30°N say)we obtainIn the above equation ρ is thedensity; (?), the zonal wind; v, the meridional wind; R, the earth's radius; Ω, the angular speed-of the earth's rotation; dm, the mass element of the atmosphere; dτ, the volume element; ds, the area element on the earth's surface, and dσ, the urea element on the vertical surface over the latitudial circle of 30°N. The first two terms (in the parenthesis) On the left side of (2) are evaluated from the mean westerlies in summer and winter given by Mintz. The last two terms on the left and the first two terms on the right side of (2) are evaluated from the mean surface pressure charts of July and January. The transfer of angular momentum across latitude 30°N given by Starr and White is used to evaluate the 3rd. term on the right. Then the value of the last two terms in the parenthesis on the right of (2) is calculated. The result agrees very well with that obtained by other authers.It is further found that: 1. From summer to winter the transfer of angular momentum from low to high latitudes by gross weather systems overcompensates the destruction by the earth's surface. The small residue of these two factors acounts for the main part (about85%)of increase of westerly circulation from summer to winter. The remaining small part of the increase of the westerly circulation may be acounted for by the advection of mass of the atmosphere, which carries the angular momentum due to earth's rotation (difference between the first two terms on the right and the last two terms on the left side of (2)).2. The transfer of angular momentum or the destruction of angular momentum, as well as the intensity of the westerly circulation has annual variation. However this annual variation is not of sine or cosine type, i,θ, the variation from summer to winter is not the opposite of that from winter to. summer. The property of this asymmetry is explained by the irreversible heat addition and subtraction. From winter, to summer heat is added to, and summer to winter heat is subtracted from the atmosphere (N.H.). Since the process of adding and subtracting heat is irreversible, the variation from summer to winter can not be symmetric to that from winter to summer.3. Transfer of angular momentum from easterlies to westerlies occurs mainly in the period of breakdown of zonal circulation (low index), mainly in the belt of longitudes of"extended troughs" (troughs extending from high to low latitudes) and "extended ridges" (ridges extending from low to highlatitudes), and mainly in the high levels of the atmosphere.

把30°N以北大气角動量平衡方程由七月積分到一月,則其中各項都可計算:此緯度以北大气相对西風角動量的改变可用Mintz平均西風冬夏分佈圖算出;地轉角動量的改变可用冬夏地面平均气压圖算出;通过30°N緯度的角動量的渦動輸送已为Starr和White算出,因此利用積分結果可求得30°N以北地面应力和山脈东西兩側气压差所引起的角動量消耗,結果与别的作者用别的方法所得數值極为符合。 作者更指出: 1.从夏到冬大型天气系統的角动量輸送勝过地面摩擦的消耗,从夏到冬西風环流增强的主要部分(約85%)即由於二者之差,西風环流增强的其餘一小部分則由於大气的質量平流,而引起地轉角動量的傳送。 2.角動量的输送,角動量的消耗以及西風环流强度都有年变化。但这种年变化並非正餘弦型,即从夏到冬的变化並不正是从冬到夏变化的反面,此种非对称性可由加熱过程和减熱过程的不可逆性解釋。在北半球从冬到夏对大气來说是加熱的,而从夏到冬大气失去熱量,因为加熟过程和減熱过程都不是可逆的,故从夏到冬的变化也不与从冬到夏的变化对称。 3.东風帶向西風帶的角動量輸送,主要發生於西風环流破坏的時候;主要發生於“引伸槽”和“引伸脊”的經度帶;同時也主要...
