四价的

At low HNO3 concentration and dilution factor above 2, 0.1 mol/L DCH18C6/1-octanol extracts very little americium,plutonium and uranium.The distribution ratios of Am、Pu and U increase with the increase of HNO3 concentration in aqueous phase,and decrease with increasing of dilution factor of HLLW.The distribution ratio of extraction of Pu increases with the increase of extractant concentration.

研究结果表明，在低硝酸浓度和较大稀释倍数情况下，DCH18C6对镅、钚、铀的萃取分配比都比较小，并随着水相硝酸浓度的增大而增大，随着模拟高放废液稀释倍数的增大而减小，提高萃取剂浓度会增大四价钚的萃取。

We also studied the structural distortion of the MnO〓 octahedron induced by the vacancies of the A-site in manganite, and the influence on the magnetic and transport properties.

在本文中，我们研究了四价离子在锰位掺杂对锰氧化物材料性能的影响，并比较了上述两种理论的适用性和合理性；同时，我们还研究了A位空穴锰氧化物体系中MnO〓八面体的结构畸变，以及对磁学特性和电导行为的影响。

Our aim was to do a combined analysis of three randomised clinical trials to assess the effect of a prophylactic quadrivalent HPV vaccine on the incidence of these diseases.

我们的目标是通过三组随机临床试验的联合分析来评估预防性四价体HPV疫苗在这些疾病发病率中的作用。

ACIP has previously recommended quadrivalent meningococcal conjugate vaccine (MCV4; Menactra , Sanofi Pasteur) for all persons aged 11 to 18 years, as well as for persons aged 2 to 55 years who are at increased risk for meningococcal disease.

ACIP过去建议所有11至18岁的青少年、以及2至55岁且处於脑膜炎疾病风险的人们都应该接种四价脑膜炎球菌接合疫苗（MCV4；Menactra；赛诺菲巴斯德公司）。

The controlled experment shows dinuclear [Cu22] is the intermediate for tetranuclear [Cu44].

控制的实验表明二核的[CuI22]是四核的混合价铜配合物[Cu44]的中间体

It was found that electrode coating was mainly composed of tetravalent tungsten oxide and nickel oxide by using XRD and EDS analysis.

通过阴极电沉积在钛基体上制备了掺杂Ni元素的WOX涂层电极，采用XRD、EDS分析认为涂层主要是四价钨的氧化物及镍氧化物的混合物。

CITIC Securities report further pointed out that the companies within the next three years of seasonal influenza vaccine will be 2.5 billion in sales revenue, tetravalent meningitis vaccine revenues will reach 2 billion yuan, hepatitis B vaccine revenue at 1.2 billion yuan, will become the company's vaccines business The main driver of growth is forecast to the company in 2009 -2011 years of EPS were 0.87 yuan, 1.06 yuan and 1.41 yuan, to maintain the company "overweight" rating, target price of 44.55 yuan.
