查询词典 chromosome

在电离辐射作用下，野蚕染色体结构异常的表现主要为易位、缺失、倒位等，其中易位的类型为相互易位和简单易位；缺失的类型为中间缺失和顶端缺失。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

然后，对这些线性光谱特征利用遗传算法结合训练样本计算类内/类间距离搜索最优分类子集，其具体染色体编码取可能的特征号，适应度函数基于样本平均Jeffries-Matusita距离计算。

Results Acute oral LD50 were 278 mg/kg and 56.2 mg/kg in rats and mice respectively, while dermal LD50＞2 000 mg/kg and inhalative LC50＞3 000 mg/m3. Skin and eye irritancy were estimated to be negative and mild respectively. Cumulative coefficient was 2.3 and allergic rate was 0%. A negative result was observed in Ames assay while increased frequencies of bone marrow micronuclei and spermatocyte chromosome aberrations were noted in the high dose (11.24 mg/kg) group.
