So its necessary to take a research on this subject. Micro fluidic chips are a special use of Micro system in modern medicine and analysis chymistry. Micro fluidic chips are made in batchs in our country now, but it is necessary to inspect the Micro quality of them as we can make them used widely.The depth measurement of micro channels is one of the most important task in the inspection of micro fluidic chips.

微流控芯片是微系统在现代医学和分析化学中的一个实际应用，目前微流控芯片已经在我国开始大量的加工制造，但微流控芯片要广泛的运用，必须对生产的芯片的各个尺寸进行微观的质量检测，微流控芯片流道深度检测是芯片尺寸检测的一个重要内容，本文开展的基于D.F.D。

We study dynamics of the hydrogen atom near a metal surface using the closed orbit theory, and discuss its changes of properties with the varying of the distance d between the atom and metal surface.

采用闭合轨道理论研究了近金属表面里德堡氢原子的动力学性质，讨论了氢原子电子的运动性质随原子与金属表面距离d变化的情况。

By measuring changes of Plasma levels of GMP-140, GP lib/III a and D-dimer in patients with OSAS before and after the institution of nasal continuous positive airway pressure, we want to study whether plate activation and enhance coagulability, fibrinolytic activation occur and play a role in prevalence ofcerebrovascular and cardiovascular events in patients with OSAS and the association with hypoxemia, if so, whether therapy with nCPAP alters this effect.

我们通过检测OSAS患者血浆α-颗粒膜蛋白(GMP-140)、血小板膜糖蛋白Ⅱb／Ⅲa和D-二聚体的变化，了解OSAS患者体内是否也存在血小板活化、凝血激活和继发纤溶亢进及其与低氧血症的关系，进一步从分子生物学角度探讨血小板活化、凝血激活和继发纤溶亢进在OSAS发生发展中的作用及经鼻持续气道正压通气对其影响。

Under the concave transaction costs function, using the variance of profolio return rate to express profolio risk, and taking the risk-return combination difference as the objective function, we propose Mean-variance D.C- integer optimization model under concave transaction costs and minimal transaction unit constraints.

2考虑凹交易费用函数，用投资组合收益率的方差反映组合风险，以风险-收益的组合差作为目标函数，提出了考虑交易费用及最小交易量的均值—方差D.C-整数优化模型。

For a connected graph G we denote by d the number of pairs of vertices at distance k.

设G是一个连通图，我们用记号d来表示图G中所有距离为k的顶点对的个数。

He'd also stay up meowing for hours some nights, and we'd call it his 'Elvis croon.'
