It also reported that cells treated with edelfosine came through the whole cell cycle without nuclei cleavage, and cells were blocked in G_0/G_1 and subsequent formation of quadplex or octploid nuclei. However, the mechanism still is unknown that edelfosine inhibits cytokinesis.

也有报告指出，依地福新处理过的细胞能经历完全的细胞周期，但不能进行分裂，使细胞聚集在G_0／G_1期，形成四倍体或八倍体细胞。

In-situ synthesis process was used to prepare copper nanoparticles and coppernanoparticles-polyethylene glycol oil solution by reduction of copper acetate by glycol in polyethylene glycol containing amido ligand as dispersant.

采用原位合成法以聚乙二醇400作为反应介质，以氢氧化钠和氨基配体作为分散剂，用乙二醇还原六水合乙酸铜制备出纳米Cu粉和纳米Cu聚乙二醇溶液，用X射线衍射仪和透射电子显微镜表征其结构，在四球摩擦磨损试验机上评价了含不同质量分数纳米铜粉的聚乙二醇溶液的摩擦磨损性能，并与分散剂进行对比。

Meat-obtain ratios are considerable different because of the size difference of 4 kinds of freshwater fish, Grass Crap highest, which was 34.79%, Silver Carp and Bighead 24.6%, Crucian 15.56%.

鲢鱼、鳙鱼、鲫鱼和草鱼四种淡水鱼的鱼体大小不同，采肉率存在明显差异，其中草鱼的采肉率最高(34.79％)，鲢鱼和鳙鱼次之(24.6％)，而鲫鱼采肉率最低(15.56％)。

Rough side of the flat fish hippocampus, complete package in the bone ring; trunk by a ring composed of 10 to 12 medial phalanx; tail was slender four-prism, thin end tip that can curl grip; head bent, and the trunk into a large obtuse or right angle, at the top of a prominent crown, crown with small side ...

海马鱼体粗侧扁，完全包于骨环中；躯干部由10～12节骨环组成；尾部细长呈四棱形，尾端细尖，能卷曲握；头部弯曲，与躯干部成一大钝角或直角，顶部具突出冠，冠端具小。。。

Smearing apical point with a mixture of 0.2% colchicine plus adeps lanae and 1.5% DMSO was also effective with doubling frequency 14.0%. Dripping the apical point of plantlets with trifluralin has also been tested, and it showed effective in inducing tretraploid from double haploid, but obviously delayed plant growth.

本试验还用具有抗微管形成的除草剂氟乐灵进行黄瓜幼苗滴苗加倍试验，试验结果表明，在进行黄瓜双单倍体诱导纯合四倍体时，氟乐灵具有使染色体加倍的功能，但同时也具有延迟处理植株生长的作用。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。
