     Because the NAT devices translate only the IP address in the IP layer and the Port number in the TCP/UDP layer, when the SIP message passes NAT device, the IP address and port number in IP layer and TCP/UDP layer are translated but the IP address and port number embedded in SIP messages are not, resulting inconsistency of the addressing information which leads SIP addressing to failure and the medium channel can not be setup.

Once the configuration of a rigid frame (including the lengths, crosssections, supporting connections, etc. of all its bars) has been laid out, there exists one set of frame constants, which expresses the elastic characteristics of the frame, and, therefore, is independent of its loading condition. By employing these frame constants, not only the computations of the end moments of all the bars under any one loading condition are greatly simplified, but also, when the frame is to be analyzed under several...

Once the configuration of a rigid frame (including the lengths, crosssections, supporting connections, etc. of all its bars) has been laid out, there exists one set of frame constants, which expresses the elastic characteristics of the frame, and, therefore, is independent of its loading condition. By employing these frame constants, not only the computations of the end moments of all the bars under any one loading condition are greatly simplified, but also, when the frame is to be analyzed under several loading conditions, the computations related and not related to loading are distinctly separated, and, therefore, the repeated portion of computations for each loading condition, unavoidable otherwise, is entirely eliminated. As most of the rigid frames encountered in practice have to be analyzed always under many loading conditions, the practical superiority of the methods employing frame constants over other methods is thus obvious.

The principal object of this paper is to present a direct method of finding the elevation of the exposuae station and conseqently the tilt and the swing, if desired, of an aerial photograph. Since the elevation of the exposure station is found, the plumb-line coordinate system can, in the sense of numerical calculation, be established however. The determination of the plumb-line coordinate system, relating to three ground control points and their cooresponding images on the photograph, means a determination of the position of the photograph in space. As can be seen the plumb-line coordinate system is definitely independent of the swing of an aerial photograph, the swing is not necessary in solving the space resection problem as the classical procedure done.The treetment in this problem involves only simple computations and produces exceptionally accurate results, as indecated in a numerical calculation during the preparation of this paper. Owing to the impossibility of publishing the numerical example in whole length, only the final results are referred here for comparing:

本文的目的,在於推導出一直接的算學方法,以求空中攝影的高度,進而求出其像片的倾角;如有必須時也求出像片的旋角來,但在本文的理論推導過程中,過去一般認為要先解决旋角的問題,而後才能解決空間定位問题的歷史看法,已經完全修正;旋角並不是解决空間定位問題所必須的。因為攝影高度既經决定,我們可以建立一垂綫坐標系,與像片在空間的轉動無關。每一像點在此垂綫坐標系上的關係完全可以藉攝影高度的得知而決定;此種關係的決定即相當於像片在攝影瞬間的空間位置的决定。這對於無論是像片的糾正、製圖、交會定點都是非常有幫助的。本文所論的方法,經數字計算的結果,表明精度是很高的,而計算手續也是簡便的。由於避免篇幅過長故未將全部計算例引出,只在此地列出一結果以相比較:

(1) Sodium salt of reduced codehydrogenase I has been obtained in good yield as a dry powder from codehydrogenase I by reduction with alcohol and alcohol dehydrogenase. This preparation was stable for at least 5 months when kept dry at -15℃. (2) The properties of the particle-bound codehydrogenase I cytochrome reductase system in heart muscle preparation were found to differ considerably from those of the soluble enzyme as obtained by Mahler et al. Among other things, the affinity for cytochrome c of the particle-bound enzyme is much greater than the soluble enzyme. The Michaelis constant for cytochrome c of the former is only one twelfth of that of the latter.(Fig. 2A). (3) With either oxygen or excess cytochrome c as electron acceptor, it was found that the overall activity, in terms of rate of oxygen consumption or cytochrome c reduction, when both succinate and reduced codehydrogenase I were oxidized simultanously, did not represent the sum of the rates of oxidation when these two substrates were separately oxidized but equalled only the faster of the two separate oxidation rates(Fig. 5, Tables 1, 2). If 2,6-dichlorophenol indophenol was used as the electron acceptor, the overall rate of simultaneous oxidation of these two substrates was found to equal exactly the sum of the rates of separate oxidation(Table 3). (4) When either oxygen or excess cytochrome c was used as the electron acceptor, reduced codehydrogenase I and succinate each inhibited the rate of oxidation of the other(Figs 4, 6 & 7). Evidence has been presented to show that the inhibition of succinate oxidation by reduced codehydrogenase I is not due to the accumulation of oxaloacetate. (5) When malonate was also added to the reaction mixture, succinate no longer produced any inhibition of the oxidation of reduced codehydrogenase I(Fig. 8). (6) It is therefore concluded that in heart muscle preparation both succinate and reduced codehydrogenase I are oxidized by cytochrome c through a common, velocity limiting factor. This is in accordance with the view previously reached by some workers from studies on the action of certain inhibitors. However, it should be noted that in our experiments no agents which might produce any conceivable change in the colloidal structure of the enzyme system has been employed. (7) It should be emphasized that our results clearly show that great caution must be exercised in drawing conslusion on the role an enzyme might play in a complex enzyme system from studies of the properties of a solubilized enzyme. (8) It is believed that the competition of two enzyme systems for a common linking factor as demonstrated in this report has provided a new method for studies on the mutual relations of two or more enzyme systems.

(一)本報告提供了一個從輔酶Ⅰ,用酶還原法製備還原輔酶Ⅰ的方法。我們所製得的還原輔酶Ⅰ鈉鹽乾粉,可以在低温保存數月而不被氧化。 (二)與心肌製劑中顆粒相結合的輔酶Ⅰ細胞色素還原酶系,和用乙醇抽出的水溶性的輔酶Ⅰ細胞色素還原酶的性質頗不相同。其中比較重要的不同點是對於細胞色素c的親力,前者遠大於後者,其米氏常數僅約為後者的十二分之一。 (三)用一心肌顆粒製劑作為材料,無論用氧或過量之細胞色素c作為氫受體,還原輔酶Ⅰ與琥珀酸同時氧化時的總速度,不等於二者分別氧化時速度之和,而僅等於其中氧化較快者單獨氧化時之速度。但如用[2,6]二氯靛酚作為氫受體時,二者共同氧化時之總速度完全等於二者分別氧化時速度的和。 (四)當用氧或過量之細胞色素c作為氫受體時,琥珀酸與還原輔酶Ⅰ能彼此互相抑制對方氧化的速度。有足夠的實驗材料說明,還原輔酶Ⅰ對於琥珀酸氧化的抑制,不是由於草醯乙酸聚集的緣故。 (五)如果在反應混合物中同時含有琥珀酸脫氫酶的專一抑制劑,丙二酸,則琥珀酸對於還原輔酶Ⅰ氧化作用的抑制即被解除。 (六)根據以上的實驗結果,可以認為,還原輔酶Ⅰ及琥珀酸先通過一個共同的因子與細胞色素c作用。這個共同的因子在一般情形之下,也是...
