Having noticed that in some organic solution , the surface of the nanosized diamond particles can get some negative voltage for they can absorb some ions , we can make the nanosized diamond particles calculated on the cathode by the cathodic electrophoretic method , which is important to make the cnt and the nanosized diamond particles composed materials 在合成材料的制备过程中,考虑到金刚石超微粉在一些有机溶液中因为其表面会吸附上一些带电的离子,所以会带上微弱的电压。因此能通过电泳的办法使得金刚石超微粉在阴极得到沉积,这对碳纳米管与金刚石超微粉合成材料的制备有着重要的意义。
A diploid - dependent regulatory apparatus was proposed by prof . luo et al to regulate gene expression . the haploid condition results in obstruction of gene expression and abnormal development because the diploid - dependent regulatory apparatus will regulate gene expression in the haploid embryos according to the same rule as in the diploid embryos . to study the difference at the protein expression level of the embryos of haploid and diploid in development and to identify the important proteins associated with the embryonic development , we extracted the total proteins of both the gynogenetic haploid and diploid embryos of goldfish in the same eye formation stages ( divided into the substages of he - 1 and de - 1 , he - 2 and de - 2 , he - 3 and d e ~ 3 respectively ) 为了研究在金鱼雌核发育单倍体和二倍体胚胎发育过程中的蛋白质表达水平的差异，并鉴定一些与发育相关的重要蛋白质，我们以遗传背景一致的金鱼雌核发育单倍体和正常二倍体的相应眼睛形成的发育阶段的胚胎为材料( 3个时期，分别为he - 1和de - 1 ， he - 2和de - 2 ， he - 3和de - 3 ) ，然后提取胚胎的全蛋白，用二维聚丙烯酰胺凝胶电泳的方法进行蛋白质点的分离，获得了质量较好的凝胶图谱，结果显示大部分蛋白质点分布在ph5 - 10 ，相对分子质量在10000 - 50000da 。
All of our products are manufactured with advanced chemical techniques high class directions for producing and part of raw materials imported from other countries and through strict quality management . at the same time , with a view to protecting environment and customer s health , all of raw materials we apply are environment - protecting , low or no noxious . we band ourselves to most advanced producing techniques for our customers 本公司生产的br - bt表调剂具有表调效果好，处理面积大1500平方米公斤，稳定性高，抗硬水能力强等优点，与各种配方的锌系磷化液均有优良的配伍性，适合于喷漆喷塑电泳的前处理，已大量应用于汽车冰箱空调自行车等行业，获得广泛好评。
Section : this paper dealed with the effects at different concentrations of hg2 + on the esterase isoenzyme ( est ) of the gill , heart , hepatopancreas and gonad in freshwater crab sinopotamon yangtsekiense by using polyacrylamide gel electrophoresis ( page ) . the crabs were exposed one week . the concentrations of mercury were omg / l , 0 . 0547 mg / l , 0 . 1727 mg / l , 0 . 5457 mg / l and 1 . 7244mg / l 汞对长江华溪蟹四种器官酯酶同工酶的影响采用聚丙烯酰胺凝胶电泳的方法，以体外暴露的方式，测定了长江华溪蟹鳃、心脏、肝胰腺、性腺四种器官酯酶同工酶的变化。
