时标

A vast amount of material and data been analysed and synthesized, the database of aerodynamic force and moment of the aircraft was built.

对于时标分离后所设计的快、慢回路的控制律，又进行了鲁棒性设计。

The 1s electron cloud in hydrogen atom has the largest probability density distribution around a spherical shell with Bohr radius a 0. The author thinks the probability density distribution and electron cloud belong in fact,to statistic regularity, and imply a macro-time scale is used, therefore in hydrogen molecule the product of energy and time is far larger than Planck Constant.

氢原子中 1s电子的电子云呈球形，电子的最大几率密度分布出现在玻尔半径a0 的球壳内，认为几率密度分布及电子云属统计规律，意味着已经使用了宏观时标，这样就使氢分子体系中能量和时间的作用量远大于普郎克常数；根据电子云的交叠，用经典力学计算了基态氢分子的结构常数，获得键长、键能及力常数的表达式分别为Re=2a0 ，De=ze/4 2a0 ，k=ze/2 2a30 ，采用原子单位 a 。u 。

In mathematics, the time scale calculus is a differential equation and differential equations in a uniform.

在数学中，时标微积分是差分方程和微分方程的一种统一。

In this paper, we analysis this problem in details, and regard that the radiation induced by curvature of shocked magnetic field lines plays a significant role in GRB emissions.

它具有极高的能量、极猛烈的爆发、极短的时标和极其复杂的时间结构和能谱结构，是宇宙中最剧烈的爆发现象之一。

The increased gravitational potential then accelerates cosmological time.

Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。

By means of integral inequality and Kartsatos transformation, we investigate first-order impulsive delay dynamic equations on time scales. Several sufficient conditions of oscillation are obtained.

利用积分不等式和Kartsatos转换技巧，研究了时标上一阶时滞脉冲动力方程，得到了一些判断这类方程解的振动性的充分性条件。
