From the fiscal angle,the key to the rural tax reform is to establish public finance,leveled finance,democratic finance and legal finace.

从财政的角度看，"深化"农村税费改革的关键是建设公共财政、分级财政、民主财政、法制财政。

After adjustment for age, Killip class, and reperfusion status, compared with patients in the first aldosterone quartile group, those in the highest quartile were at higher risk of death (hazard ratio 3.28, 95% CI 1.09 to 9.89, P=0.035) and resuscitated cardiac arrest (hazard ratio 3.74, 95% CI 1.40 to 9.98, P=0.008)during the follow-up.

在对年龄，KILLIP分级和再灌注治疗等因素进行了调整之后，我们发现与低血浆醛固酮水平患者相比，高血浆醛固酮水平者有较高的死亡风险（危险比3.28， 95% CI 1.09 to 9.89， P=0.035）和随访期间较高的心跳骤停发生率(危险比 3.74， 95% CI 1.40 to 9.98， P=0.008)。

Graduate the volume from pianissimo to fortissimo.

The chemical and structural propert ies of the humic acids before and after fractionation were characterized by elem ental analyzer, Fourier transform infrared spectrometry, solid state 1 3C-nuclear magnetic resonance spectrometry (13C-NMR) and pyrolysis-gas chr omatography-mass spectrometry.

利用切面流超滤技术将Pahokee泥炭腐殖酸分为相对分子质量不同的8个级分，并综合应用元素分析和傅立叶变换红外光谱、固体13C核磁共振(13C NMR)和裂解-气相色谱-质谱技术详细研究了分级前后腐殖酸分子的结构组成特征。

Up to now, there is not any intact method which can quantificationally extract and analyze the soluble titanium in soil and fractionate titanium forms.

因此，研究土壤中钛的分级测定，对钛在土壤中的行为和肥力特征都具有重大意义。
