查询词典 variation

The pupae were exposed to 9 krad 60Co-γ rays for two days before emergence.The adults were dissected and many mature sperms could be seen in the male flies.There were no significant difference in the form,number and vigor of sperm between irradiatid and unirradiated male flies,but there were some abnormal ultrastructurail changes in the sperm of irradiated male flies such as the appearence of vacuoles in nutrient cells,disarrangement of sperms,variation of the number of chondriosome derivates,axonemes ction of formation and abnormal cell division of sperm cells.

用9krad辐照羽化前2天的蛹，成虫羽化后解剖观察，雄虫已有大量成熟精子，精子形态、数量和活力与未经辐照处理的雄虫无显著差异，但其超微结构则发生了某些异常变化，如营养细胞出现空泡、精子排列零乱、线粒体衍生体和轴丝增多或减少、构型被破坏、精子细胞分裂异常等。

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。

The Chondrite normalized REE pattern shows typical enrichment of LREE, with ∑REE peaking up to 318 mg kg^(-1) in central layer of the profile. Both Ce and Eu have a similar trend of variation in the profile, i.e. positive anomaly-negative anomaly-positive anomaly from bottom to top. The highest ∑REE value occurs where negative Ce and Eu anomaly and relatively higher Fe(superscript 2+)/Fe(superscript 3+) values also occur.

剖面稀土元素分布型式为轻稀土富集型，∑REE在风化壳中部达到最高值318 mg kg^(-1)，剖面上Ce和Eu均呈正异常－负异常－正异常变化趋势，∑REE最高值出现在Ce和Eu负异常和Fe(上标 2+/Fe(上标 3+)较高层位，∑REE与Fe2O3显著正相关。

Then we investigate a variation of the edge game chromatic number of a graph called edge game chromatic numberⅡ, and also we give the upbound of edge game chromatic number II of some simple graphs.

我们还提出了第二边对策色数这个概念，在此基础上给出了几类简单图的第二边对策色数的上界。
