After matching each pair of homologous chromosomes that bivalent.

The new formulation is known as B.O.P.V., or bivalent oral polio vaccine.

A light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine).

轻而软的银白色二价金属元素，纯净状态下燃烧会发出明亮白光，仅天然存在于化合物中（如菱镁矿、白云石、光卤石、尖晶石、橄榄石）。

The reduction of chromosomes in the hybrid and the high numbers of bivalents were possibly due to the chromosome of Crambe abyssinica eliminating and the genome of Brassica.

杂种PMC减数分裂中，平均配对构型为0.06Ⅲ+11.26Ⅱ+3.80Ⅰ，二价体数目变化于8～13之间，以10Ⅱ、11Ⅱ、12Ⅱ的细胞出现频率较高，分别为26.60%，23.91%和30.98%，单价体数目变化于0～8个之间。

At last, adsorbent and covalent Ag nanoparticles modified electrodes were prepared by adsorbent and covalent method, respectively. The electrochemical behaviours of SCN-, brilliant cresyl blue and nicotinamide adenine dinucleotide on modified electrode were studied by Cyclic voltammetry, differential pulse voltammograms and electrochemical impedance spectroscopy.

最后，用吸附法和共价键合法制备了吸附型和共价自组装银纳米修饰电极，采用循环伏安法、示差脉冲伏安法和交流阻抗谱等电化学方法研究了SCN-、灿烂甲酚蓝和还原型烟酰胺腺嘌呤二核苷酸的电化学行为。

Diakinesis bivalents end of some of the homologous chromosomes together only at the end.

终变期末有些二价体的同源染色体只在末端连在一起。

正常株的花粉母细胞在终变期晚期二价体形态

Two signals of 45S rDNA were mapped on the mitotic metaphase chromosomes in the F1 hybrids, respectively, and one signal was present on a bivalent during meiotic of synaptene, diakinesis, and metaphase I. We inferred that the two mitotic chromosomes carrying 45S rDNA were homolo-gous pairs.

在有丝分裂中期染色体上2个杂种分别检测到2个杂交信号，在减数分裂粗线期、终变期、中期Ⅰ染色体上45S rDNA位于一个二价体上，说明这两个杂种携带45S rDNA的染色体为同源染色体。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
