Let f(z)=z+sum from n=2 to ∞ a_nz~n be regular and schlicht in the unit circle. M. Schiffer proved that the function w=f(z) in the class of such functions, which renders |a_κ| the maximum, maps |z|<1 onto the whole W-plane with a finite number of analytic cuts. For the cases k=4 and k=5 Schaeffer-Spencer [3] and Golusin [5] proved respectively that there is only one cut for the extremal domain.

Let f(z)=z+sum from n=2 to ∞ a_nz~n be regular and schlicht in the unit circle. M. Schiffer proved that the function w=f(z) in the class of such functions, which renders |a_κ| the maximum, maps |z|<1 onto the whole W-plane with a finite number of analytic cuts. For the cases k=4 and k=5 Schaeffer-Spencer [3] and Golusin [5] proved respectively that there is only one cut for the extremal domain. The principal object of the present paper is to show that the same thing holds true for the cases k=6 and k=7. Our proof depends upon the following lemmas: Lemma A. If{f(z)~2}_6=0; then |a_2|<1.63; and if {f(z)~2}_7=0; then |a_2|<1.77; Where {g(z)}_n denotes g~((n))(0). Lemma B. If |a_6|≥6 and {f(z)~2}6=0, than |a_2|>1.95, If |a_7|≥7 and {f(z)~2}_7=0, then |a_2|>1.85. Using merely the method of variation, without appealing to L(?)wner's method as done by M. Fekete and G. Szeg [6], we can prove the known theorem that (?)|a_3-αa_2~2|=1+2 exp(-2α/(1-α))(0≤α<1) with the "uniqueness" of the extremal function. For the functions f(z) satisfying the pair of conditions R(a_3)>0 and R(a_2)<0, we can pnove that the greatest value of R(a_2+a_3)is 1.03…,and that the correspondiong extremal function is of real coefficients.

S表示單位圆|z|<1上單葉且正則的函數 f(z)=z+α_2z~2+α_3z~3+… (1.1)的全體所成之族。設S′是S的一個子族,S′中任一函數满足條件 R(α_3)>0,R(α_2)<0。對於S′中的函數,本文證明R(α_2+α_3)之最大值是可以達到的,其值是1.03…。達到此值的極值函數的一切係數都是實數,極值函數只有一個。舍勾和飛克得[6]謝缶和斯賓塞爾[3]以及沙拉烏洛夫先後用樓五納的參數表示法和變分法,求出 |a_3-αa_2~2|(0≤α<1)的值,並指出達到此值的極值函數的一切係數都是實數,而且極值函數只有一個。本篇僅用變分法来建立他們的定理。惜缶[4]指出使|a_n|達到最大值的函數(1.1),其映象區域的境界是一組伸展到無窮遠處的解析若當曲綫。謝缶和斯賓塞爾[3],戈魯辛[5]分別證明對於|a_4|和|a_5|的極值區域,其境界綫只有一根。本篇對於|a_6|和|a_7|證明同樣的事實。證明是靠着如下的引理:

Methods of soil and vegetation survey generally used for forest trees in mountainous areas are considered inapplicable to poplars growing as scattered trees on the levelland. In the present paper, therefore, a method catering for this purpose together with the result of its application to poplar sheltabelts in East Honan is presented. In soil survey, besides detailed profile descriptions, field determinations of important soil properties, including water permeability, volume weight, moisture content, texture, ground water table and composition, thickness and depth of clay layer, pH value, available N and available P have been obtained. All the data are later annalysed and interpreted from two rather different but complementary approaches. On the first hand, by the calculation of correlation coefficient, correlation between height growth of Populus pyramidalis and ground water tables is found to be significant (r=0.458 P<0.05), and correlation between height growth of this species and volume weight of soil at root-concentrating horizon highly significant (r=0.804 P<0.01). But correlation coefficient between height growth of the same species and all other studied soil properties fall below the significant leyel generally adapted i.e. 5% level. Secondly, on the comparative study of field determinations of soil properties and height measurements of this species, ground water tables with reference to tree heights are divided into 3 classes, soil textures 4 classes, pH values (at root-concentrating horizon) 3 classes, and volume weights 3 classes respectively. In vegetation survey, qualitative investigations are carried out following the ZurichMontpellier School's procedures with but a few modifications, and total estimation, sociability, aspect, life form, root system and plant height are recorded. Also, point quadrat method is employed to collect quantitative data such as cover and frequency. Populetum pyramidalise association is classified into two subassociation:P. Pyr. Imperata cylindrica subassociation and P. Pyr. Imperata cylindrica var. major subassociation respectively. The latter is further classified into Lactuca variant and typical variant. To the above-mentioned plant community units and their respective differential species, a weighted mean of the class value with respect to each soil property is calculated separately. On this basis their indicating values to the growth of the tree are interpreted. Meanwhile, quantitative criteria of soil properties and a list of plant indicators (including individual species and community units) for the choice of planting sites of Populus pyramidalis in the studied area are given. Lastly, merits and demerits of the present method are discussed.

There are six sections incorporated in this paper. In the first section a brief sketch concerning the development of a phylogenetic contour of the plant kingdom, especially the part of Spermatophytes, is given. The contour here means only the classification of Spermatophytes inio Gymnospermae and Angiospermae, the latter into Dicotyledoneae and Monocotyledoneae, and the Dicotyledoneae into Archichlamydeae and Metacchlamydeae; but the accomplishment of it was achieved by the continuous efforts of various bo-...

There are six sections incorporated in this paper. In the first section a brief sketch concerning the development of a phylogenetic contour of the plant kingdom, especially the part of Spermatophytes, is given. The contour here means only the classification of Spermatophytes inio Gymnospermae and Angiospermae, the latter into Dicotyledoneae and Monocotyledoneae, and the Dicotyledoneae into Archichlamydeae and Metacchlamydeae; but the accomplishment of it was achieved by the continuous efforts of various bo- tanists and through a long period of more than bicentenial time. Hence the above mentioned contour is here regarded as an invaluable compendium in the classification of Spermatophytes. The second section deals with the leading subjects of Dicotyledoneae of the contour. Because of some taxono- mists, as Hans Hallier (1912), Alfred Gunderson (1950), and Lyman Benson (1957), who have proposed respectively four, ten, and five superorders under the class Dicotyledoneae, the two subclasses Archichlamydeae and Meta- chlamydeae have been thus abandoned in their books. These superorders appear to be somewhere more natural in the arrangement of related families in certain orders than the two subclasses, but they are certainly less ten- able in practice. Besides 15 family-groups, Dr. John Hutchinson (1959) has revived the two groups Lignosae and Herbaceae instead of the two subclass- es for the classification of his Dicotyledons. This kind of Hutchinson's system seems to be quite inadequate and readily misleading to an error of phylogeny. Furthermore, in this section is also mentioned the system of Dr. A. A. Grossgeim (1945), in which the two classes Dicotyledoneae and Mo- nocotyledoneae are even abolished, but 11 groups (stocks) and 23 superorders have been used instead. Perhaps this system is the most complicated one in the modern classification of Angiosperms and hardly acceptable for practical uses. In the third section the principles for settling the systematic positions of some orders and families are suggested. There are three items given in it. The first item emphasizes that a set of reproductive and vegetative charac- ters must be taken into consideration and comparison before a certain family is settled in a certain order; the second states that the formal similarities in some characters must be distinguished from the phylogenetic relationships; and the third mentions that the sequences of families in a certain order ought to be in accordance with the evolutionary tendencies of their flowers and the developmental directions of their habits and geographical distribu- tions. Finally in this section it suggests that the data from other related sciences, such as Anatomy, Embryology, Palynology, etc. should be used for references, when certain families are encountered morphologically indeterm- inable for their systematic positions. The fourth section reveals the fact that some closely related families, such as Capparidaceae and Cruciferae, Araliaceae and Umbelliferae, Big- noniaceae and Scrophulariaceae, Verbenaceae and Labiatae, etc. have been divided by Hutchinson's system (1959) into far remote orders, for one of them is fundamentally woody and the other herbaceous in habit. In order to show that these every two families in a couple are inseparable from each other and that the segregation of them into different orders could not be acceptable in phylogeny, one or more genera intermediate between them are evidenced and explained. On the other hand, some quite unrelated families, such as Calycanthaceae and Rosaceae, Nyctaginaceae and Thymelaeaceae, Elaeagnaceae and Rhamnaceae, Araliaceae and Caprifoliaceae, etc. are dis- cussed in the fifth section. They have been united by Hutchinson into Ros- ales, Thymelaeales, Rhammales, and Araliales respectively. But the group- ing of these every two families into a single order is probably based upon their formal similarities in some characters arisen from parallel developments. According to their evolutionary scales, they would be naturally fallen into different orders. Regarding the systematic position of the family Calycanth- aceae, a new suborder Monimiineae of the order Magnoliales is published here with Latin diagnosis. It is known hitherto that the three families, Mo- nimiaceae, Amborellaceae, and Calycanthaceae belong to this suborder, the first one being chosen as its type. Finally in the sixth section, it deals with the contributions of some other related sciences to the modern Taxonomy. Amongst them the three sciences, Wood Anatomy, Plant Embryology, and Palynology are given as examples. Several families, such as Eucommiaceae, Bretschneideraceae, Rhoi- pteleaceae, Cactaceae, Callitrichaceae, etc. have been regarded as doubtful or isolated ones for their phylogenetic positions. By means of the data from these sciences, they are, however, now each attributed to their proper ord- ers with certainty. Economically the most important family Gramineae is generally included with Cyperaceae in the order Glumiflorae, but recently the contributions of both Palynology (Erdtmann, 1952) and Anatomy (Sm- ithson, 1957) confirm that Grarnineae have affinities with Flagellariaceae, a member of Enantioblastae (Hallier, 1912). Although the contributions of these sciences frequently assist taxonomists in adjusting the systematic positions of some families sedis iucertae, the classification of Spermatophy- tes still in most cases depends upon the knowledge of Plant Morphology, especially of the Comparative Morphology of flowers, for the study of their phylogeny.
