查询词典 PCC

PCC, and Ceratopteris richardii. Besides these findings, both the mechanistic and mechanistic-empirical combination models were used to analyze the adaptive evolution of amino acid sites in the CVNH domain. Our results showed that:(1) neither model reveals significant sites undergoing positive selection;(2) purifying selection has played a dominant role during CVNH evolution; and (3) the MEC model better fits the CVNH data set.

在此基础上，分别采用机理式模型和MEC模型(Mechanistic-empirical combination model)对CVNH结构域序列位点进行适应性进化分析，结果显示：1两类模型均未检测到统计上显著的正选择位点；2净化选择对CVNH起主导作用；3MEC模型更适合所研究的数据。

The proof carrying code approach1, 19 does not attempt to establish semantic preservation between a source program and some compiled code. Instead, PCC focuses on the generation of independently checkable evidence that the compiled code C satisfies a behavioral specification Spec such as type and memory safety.

证明携带代码方法[1，19]不求建立源程序和所生成程序之间的语义保持特性，而是着眼于生成可以独立检查的证据，该证据表明编译所生成的代码C满足诸如类型安全和存储安全等行为规范Spec。

FMRI results showed that identification of environmental risks was associated with increased activation in the ventral anterior cingulate cortex and posterior cingulate cortex.

我们还发现，LPP/ P200的幅度和PCC激活程度与风险环境事件的主观风险和情绪评价分数正相关。

通过对重金属离子的选择吸收性多方面检测，结果表明在用来吸收水体中对人体有害的金属离子方面，转α-α基因藻有很强的选择吸收性。

Coli. The shuttle co-expression plasmids were introduced into filamentous cyanobacterium-Anabaena sp. PCC 7942 (or 7120) by a triparental conjugative transfer method.

采用双顺反子体系在pTrc载体中成功的实现了A、B和Bc亚基的单独活性表达及A、B亚基共表达。

In this work , 1,8-octodiol, the starting material, reacted with 40% hydrobromic acid to produce 8-bromooctan-1-ol, with the catalytic action of PPTs, its hydroxyl group was protected by 2,3-dihydropyran. Then it coupled with 1-heptaalkyne, by means of P-2 nickel as catalyst, stereoselectivity catalysis hydrogenated, with the catalytic action of acid to take off extremital 2, 3-dihydropyran which protected hydroxy group, then used PCC to oxidize alcohol into corresponding aldehyde.

以1，8-辛二醇为原料，与40%氢溴酸进行单溴代反应，得到8-溴-1-辛醇，在对甲苯磺酸吡啶盐的催化下与2，3-二氢吡喃反应，保护分子中的羟基，再与1-庚炔进行偶联，以P-2镍为催化剂立体选择性催化加氢，酸性条件下脱末端的2，3-二氢吡喃对羟基的保护，使用氯铬酸吡啶盐将醇氧化成醛。
