constants real
解釋
實數常數-
In the last chapter, by introducing the isochronous center of real systems into complex planar and defining complex center and complex isochronous center, a concise linear recursion formula for period constants is given, necessary and sufficient conditions of complex isochronous center ( the time - angle difference theorem ) proved, conditions of real systems with linearizable center and saddle treated unitedly and the isochronous center conditions discussed fully for a class of real planar cubic systems
在第七章，通過把實系統等時中心引入復平面研究，定義了復中心和復等時中心，給出了等時中心周期常數計算的簡明的線性遞推公式，證明了等時中心判定的充分必要條件（時角差定理人統一地處理了實系統具有可線性化的中心和鞍點條件，並對一類實平面三次系統的等時中心條件進行了完整研究 -
At the same time, the values " range of two kinds of nonsquare constants and their values in real inner product space are given. we also discuss the pointwise nonsquare constant in finite dimensional f space
同時給出了兩種點態非方常數的取值范圍，和實內積空間中兩種點態非方常數的值。討論了有限維l ~ p空間的點態非方常數。 -
Semantic structure includes " constants " and " variables ", where constants keep in harmony with the expression of selected sentence patterns, while variables are real cause that affects the sentences pattern choice
語義結構包括「常量」和「變量」 ，常量對取捨句式的表達不施加影響，而變量則是造成各種取捨句式差異的真正原因。 -
In this paper, a model developed by t. d. dorney and d. duvillaret et al is used to discuss the principle and method for optical constants extracting. the real refractive index and extinction coefficient of materials and the extraction of other material parameters are also discussed
Duvillaret等人提出的模型的基礎上研究了從thz時間波形中提取材料的光學常數（實折射率和消光系數）的原理、方法，並對于如何得到材料的其他物理參數進行了探討。 -
The features of phase and group velocity were advanced by means of preparing samples with different shaping. the phenomenon of " cusp " in group surface of quasi - shear wave ( qsv ) was observed. the inversed velocity surface according to calculated elastic constants in real orthotropic media is consistent with practical measured velocity surface
用加工不同樣品形態的方法給出了正交各向異性介質的相速度和群速度特徵，觀測到各向異性介質群速度面上的尖點現象，並用測試得到的正交介質的彈性常數進行了數學模擬，其波場特徵與測試的速度面特徵相符。
