查询词典 quadrivalent

Based on the measured refractive index distribution curve, according as the theoretical model of light transmission in the GRIN medium, using quadrivalent Runger-Kutta method to carry out the light tracking, by this means the mainly imaging character index of themicro-lens such as foci, longitudinal and transverse spherical aberrations aberration etc is calculated.i.

第五章 从测量所得折射率分布曲线出发，根据梯度介质球内光线传输的理论模型，用四阶runger-kutta方法进行光线追迹，计算了此种梯度球的纵横向球差等光学特性，给出所制作梯度折射率微球透镜成像性能的评价。

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 quadrivalent was made of the normal 11 chromosome, the normal 18 chromosome, the translocated 11; 18 chromosome and the translocated 18; 11 chromosome.

精母细胞中SC分析，在早粗线期、中粗线期和晚粗线期精母细胞中，均发现22个常染色体SC和一个XY-二价体，即23个二价体；未发现22个二价体和一个单价体细胞，说明这条rob（21q；21q）染色体的两个臂完全配对形成发夹结构，形态上与正常SC一样，但与正常21号SC相比，其相对长度变短，由正常的1.5±0.1变为1.25±0.05。

Results showed that the PMC meiosis of autotetraploid was similar to the diploid except some particularities. In metaphase Ⅰ, multivalent, quadrivalent, trivalent, bivalent and univalent were observed and some of the chromosomes were found not to rank on the metaphase plate and so did in metaphase Ⅱ cells. In anaphase Ⅰ and anaphase Ⅱ cells, there were lagging chromosomes, chromosome bridge and fragment. During anaphase Ⅱ and telophase Ⅱ, chromosome segregation was not synchronous or equal. At tetrad stage, dyad, triad, tetrad with micronucleus and polyad appeared.

结果表明，同源四倍体花粉母细胞减数分裂过程与二倍体相比，中期Ⅰ染色体构型复杂，有多价体、四价体、三价体、二价体和单价体；中期Ⅰ及中期Ⅱ有部分染色体没有排列在赤道板上；后期Ⅰ及后期Ⅱ出现落后染色体、染色体桥及断片；后期Ⅱ和末期Ⅱ有染色体不同步分离及不等分裂的现象；四分体时期还出现二分体、三分体、含微核的异常四分体及多分体。

Through X-ray photoemission spectrum, the binding of 516.4 and 523.1 eV can he attributed to the V(superscript 4+ subscript 2p3/2) and V(superscript 4+ subscript 2p1/2),, which confirm the quadrivalent slate of V ion in Li0.8V0.8O2. With a current density of 7.4 mA/g, the charge capacity of Li0.86V0.8O2 is 163 mAh/g in the first cycle, and the first discharge capacity of the materials is 113 mAh/g. After 20th cycles, the discharge capacity is still 80 mAh/g, which show good electrochemicalstbility.

在电流密度为7.4mA/g的充放电中，Li0.86v0.8O2初始充电容量达到163mAh/g，首次放电容量也能达到113mAh/g，20次循环后放电容量仍然可以达到80mAh/g，表现出较好的循环性能。

WHITEHOUSE STATION, N.J., May 9, 2007 - Today, the New England Journal of Medicine is publishing results from two Phase III studies of Merck's cervical cancer vaccine, GARDASIL [Quadrivalent Human Papillomavirus (Types 6, 11, 16, 18) Recombinant Vaccine].
