As we all know, bilateral symmetry, three - layer embryo, metamerism and having a relatively developed head are the common characteristics of the arthropoda and annelida, so it is believed that arthropod originated from annelid
由於節肢動物具備環節動物兩側對稱、三胚層、身體分節、頭部較發達等特徵，所以一般認為節肢動物起源於環節動物或類似環節動物的祖先。 -
The paper takes the example of words of " begin " & " finish ", on the foundation of surveying their combination configuration, interprets them from four angle : ( 1 ) forming words by asymmetry and symmetry ; ( 2 ) syntactic structure and semantic structure ; ( 3 ) common sememe and different sememe ; ( 4 ) polysemy morpheme and jargon transmutation
摘要本文以「開始」 、 「結束」義詞語為例，在考察「開始」 、 「結束」義詞群組合形態的基礎上，從不對稱構詞與對稱構詞、句法結構與語義結構、共同義素與區別義素和多義語素與行業轉化等四個視角進行闡釋。 -
In this paper, the high - temperature low - cycle fatigue life and fatigue crack propagation life tests are carried on the cylindrical axial symmetry specimens having precrack or non - precrack with different types of notches of 16mnr steel in common use in the petrochemical industry contacting coke drum equipment, the stress / strain and the range of stress / strain of dangerous points are received through stress analysis of the specimens using finite element program under multi - axial stress state. at last, the equations of evaluating the high - temperature low - cycle fatigue life and the fatigue crack propagation life are found through using the least - square regression method
本文採用無預裂紋和帶預裂紋環狀缺口圓柱形試樣，進行了石化焦炭塔設備常用材料16mnr多維應力狀態下不同缺口形式的高溫低周疲勞總壽命試驗及裂紋擴展壽命試驗，並利用有限元程序對試樣缺口周圍及裂紋尖端附近進行了軸對稱多維應力狀態下的應力、應變場分析，來評價材料不同條件下的高溫低周疲勞總壽命和裂紋擴展壽命，最後利用最小二乘回歸方法，得到了該材料高溫低周疲勞總壽命和裂紋擴展壽命評價方程。 -
By analyzing and studying the dynamic characteristic of the minehunting sonar array, the author points out that the minehunting sonar array posture control system is a non - linear and intense coupling dynamic system. according to characteristics of the common inertia matrix, the author testifies that the inertia matrix of the minehunting sonar array has many dynamic characteristics such as the limited boundary quality, the symmetry quality and the positive definite quality
對獵雷聲納基陣的動力學特性進行分析研究，指出了獵雷聲納基陣控制系統為非線性、強耦合的動力學系統；從一般的慣量矩陣特性入手，證明了獵雷聲納基陣的慣量矩陣具有有界性、對稱性及正定性等動力學特性。 -
