poisson constant
解釋
泊松常數-
The derived dry bulk modulus must be positive and greater than 2 / 3 of shear modulus to insure a positive lame constant and poisson ' s ratio
提取的乾燥體變模量必須為正，並且大於剪切模量的2 / 3 ，以保證拉梅常數和泊松比為正。 -
In chapter three, consistent boundary poisson structures for an open string ending on d - branes with a constant and non - constant background neveu - schwarz b fields are considered respectively, and rhe results indicate that whether field theories living on d - branes are commutative or noncommutative depends on which consistent poisson structure the observer chooses
並且，我們通過對結果的分析指出， d -膜上的場論究竟是對易的還是非對易的，主要取決于觀測者所選擇的新的自洽的poisson結構的具體形式。 -
But, in most of general risk model, the premium income is a constant rate, scholar have generalized the aggregated premium income from a constant rate process to a poisson process. in this article, the author defines the model that premium income is a compound poisson process, not a constant rate process, it is named compound poisson process premium income risk model
作者建立了保費收入為復合泊松過程的風險模型，在新的風險模型中包含兩個復合泊松過程，首先考察了復合泊松過程可加性的性質，據此性質，把這兩個復合泊松過程化簡為一個復合泊松過程，使模型得到化簡。 -
5 ) the velocity of the compressive and shear wave for the samples saturated completely by brine increases with the increasing of confining pressure ( with the constant pore pressure ), but poisson ' s ratio decreases. 6 ) some interior factors, such as the composition of rock, porosity, density and so on
5 ）在完全飽和水、溫度和孔隙壓力不變的條件下，無論是縱波、橫波1還是橫波2 ，珠江口盆地第三系砂巖、粉砂巖、碳酸鹽巖及其過渡性巖石類型的速度均隨圍壓的增大而增加；大多數情況下，泊松比隨圍壓的增加而降低。
