共生

This has led to the theory that eukaryotes arose as a result of symbiotic associations between prokaryotes.

这就形成了真核生物中某些细胞器来自于共生的原核生物的理论。

It is shown that the direct coupling between the dots can reduce the degree of the entanglement for the excitons.

利用共生纠缠度研究了单模腔场内两个耦合量子点中激子的纠缠动力学行为。

Its plate evolution can be divided into three stages: AnZ ancient-plate stage(ancient-continent accretion),Z-D plate stage(plate expansion and subduction )and C-P rift stage.

甘蒙北山地区位于哈萨克斯坦板块和塔里木—中朝板块交汇部位，其板块构造演化分为前震旦纪古板块活动时期、震旦—泥盆纪现代体制板块活动时期和石炭—二叠纪裂谷活动时期，不同构造单元及演化阶段控制了不同的含矿建造、成矿作用时空分布及演化序列和矿床共生组合。

In this paper, texture analysis method for medical CT images is presented for the discrimination of hepatic fibroses between the normals and abnormals by CT images.

采用灰度共生矩阵方法，分别提取纤维化肝组织和正常肝组织 CT图像的各种纹理特征，如能量、熵等进行对比研究。

Firstly, B-scan ultrasound images are captured form patients and the regions of interest are localized. During the feature extraction approach, three models are employed including mean intensity ratio of the near field and the far field, the gray level co-occurrence matrices and the gray level run-length matrices. 10 statistics are extracted from the three models for each image.

首先以脂肪肝B超图象纹理的变化为出发点，分别采集人体肝脏的B超图象，并选择图象中的感兴趣区域，计算出每一幅图象的近远场灰度比特征、灰度共生矩阵和灰度游程矩阵的二次统计量特征。

Grass planted in symbiosis ecosystem of fish and grass could absorb the nutrition of the waste water which supplied a feasible condition of normal growth, and was the food of the fish, so it was an important meaning.

在鱼草共生系统中，种植的牧草可以吸收循环养殖系统水中的营养物，为鱼的正常生长提供一个适宜的环境，同时生产的饲草可以养鱼，因而具有重要意义。

Unless they succeed,the yield gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated,and even if the transfer of those gene complexes,once they are found, becomes possible.

除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体，一旦被发现之后，其移植得以成为可能的话。

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。
