In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了将压电晶体谐振器用作定量测量质量的装置，并从理论上导出了频率与质量变化之间的关系式——Sauerbrey方程：ΔF=〓=-。。。

The results obtained form theoretical calculations indicate that the hydroxyl-tautomer predominate in the gas phase or nonpolar solvents, while in solvents of high dielectric constant, the tautomeric equilibria is shift in favor of the oxo-tautomer can be mainly ascribed to the polarization effects.

结果表明，2（1H）-吡啶酮类化合物在极性溶剂中表现出与气相或非极性溶剂中截然不同的的优势结构主要是由于各异构体分子极性上的差异引起的。

Firstly, based on phenomenal characteristic parameter collection and its further correlation analysis, the metabolic flux shift during late phase of guanosine fermentation was preliminarily deduced and confirmed by combining intermediates detection and the product biosynthesis pathway analysis. That is, the metabolic flux shifted from Hexose Monophosphate Pathway , from which guanosine was generated mainly, to Embden-Meyerhof Pathway and Tricarboxylic acid cycle to form amino acids and organic acids.

首先通过对发酵过程现象特征的收集和进一步的相关分析，初步推断在发酵过程后期存在有代谢流的迁移，结合中间代谢产物的分析和产物合成的代谢途径初步确认了代谢流迁移的存在，即代谢流从形成产物的HMP途径向形成有机酸、氨基酸的EMP途径、TCA循环迁移。

Objective To determine the correlation between unenhanced CT attenuation value and signal intensity loss on opposed-phase chemical shift MR imaging of adrenal tumors.

目的探讨肾上腺肿瘤的平扫CT值与磁共振化学位移成像反相位信号丢失程度的相关性。

He's also recommended that in December we begin a transition to the next phase of our strategy in Iraq, in which our troops will shift over time from leading operations to partnering with Iraqi forces, and eventually to overwatching those forces.

他也建议，在12月，我们开始转入到我们在伊拉克的下一步战略阶段，就是我们的军队将逐渐从领导行动的角色转换为辅助伊拉克军队行动的角色，从而最终达到掩护他们的军队。

He's also recommended that in December we begin a transition to the next phase of our strategy in Iraq, in which our troops will shift over time from leading operations to partnering with Iraqi forces, and eventually to overwatching those forces.

他同时建议我们从12月开始转入到我们对伊战略的第二部，我们的部队将从直接主导作战转换到协同伊军，进而最终变成掩护伊军的角色。

In this paper, a soft-switching technology scheme, which can be applied to vehicle-carried invertors, has been researched at the base of engineering practice .The principle and control strategies of soft-swiching are also discussed in detail. Furthermore, software and hardware components are discussed particularly by using shift phase control technology properly and the combination of DSP and IGBT.in result, the vehicle-carried invertors have the characteristics of small volume, light weight, high integration and high frequency.

本论文从实际应用的角度出发，研究适用于车载逆变器的软开关技术方案，详细分析了软开关技术的原理与控制策略，将移相控制技术合理利用和改进，用DSP与IGBT组合搭配，对逆变器的软件和硬件组成做细致的研究，使车载逆变器具有体积小、重量轻、集成度高和高频性能等优点。

In the mid-field measurement method,space-magnitude error and space-phase error due to the probe position shift are some special errors.

在中场测量中，探头的位置偏移导致的空间误差是其特有的测量方法误差。

The anisotropic behaviour of their thermal expansion may bemarkedly reduced by a partial substitution of Cu for Co and a shift of its com-position toward the Co enriched 2-17 phase region. Noticeably, both SmCo_(0.80Cu_(0.14)Fe_(0.06), and SmCo_(0.87Cu_(0.13)_8 are almost completely isotropic. It seems thatthey are the ideal materials for radially oriented toroids of best performace.

实验发现以铜取代部分的钴，以及成分移向富钴的2-17相区，都使热膨胀各向异性特性明显降低，特别是SmCo_(0.80Cu_(0.14)Fe_(0.06)_7和SmCo_(0.87Cu_(0.13)_8二者几乎是完全各向同性的，是制备高性能辐向磁体的理想材料。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
