It can be concluded that clonal selection algorithm is convergent, because BCA is an abstract of the generic CSA.

由于BCA是一般克隆选择算法的一种抽象，因此可以推断克隆选择算法的收敛性。

BMEICS synthesizes the character of block motion estimation and that of global search, diversity, and no prone to premature in immune clonal selection.

仿真实验结果表明，在大多数序列上，该算法都比已有的快速搜索算法具有更高的性能和更少的平均搜索点数。

BMEICS synthesizes the character of block motion estimation and that of global search, diversity, and no prone to premature in immune clonal selection. It speeds up the process of motion estimation while maintaining the average with little loss.

该方法将块匹配运动估计问题的性质与免疫克隆选择算法所具有的全局搜索特性、解的多样性和不易早熟的特点相融合，在能够获得接近全搜索方法所得到的平均峰值信噪比的前提下，使得平均搜索点数大为降低。

方法］以未退化、轻度退化、中度退化、重度退化草地上挖取的短穗兔耳草基茎及与其相连的匍匐茎和无性系分株为材料，研究不同退化草地上短穗兔耳草匍匐茎的数量、长度和单位长度匍匐茎干重的差异。

Six populations of Cypripedium flavum were studied on their genetic diversity, genetic structure, and clonal diversity in Zhongdian County, Yunnan Province (South-west China).

采用AFLP分子标记方法对云南中甸的6个黄花杓兰居群进行了遗传多样性水平、遗传结构及克隆多样性研究，其中两个居群用样方取样法分析其克隆空间结构。

Objective: To establish a protocol of rapid clonal propagation of Dioscorea zingiberensis using mature leaves as explants.

Five (22%) of the 24 T-cell tumors expressed βF1, 8 (35%) of the 23 tumors were positive for EBER, and 20 (95%) of the 21 tumors were clonal for T-cell receptor.

那24例T细胞淋巴瘤中有5例（22%）表达βF1；有23例做了EBER检测，其中8例（35%）阳性；有21例做了T细胞受体基因检测，其中20例（95%）为多克隆性重排。

Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Panorama Many people are dancing in a large sitting room.
