查询词典 selectivity

These reactions catalyzing oxidation of alcohol- OH groups have high yield and selectivity.

使用的催化剂对醇羟基的氧化具有高度的选择性并有很高的转化率。

The recycling of separative mother liquor as the source of feeding ammonia and feeding water, and repetitious regeneration of coked catalyst by the high-temperature calcination for four times seem to have no obvious influence on the activity, selectivity and durability of TEDAMAX-01 catalyst.

对将分离母液循环作为进料氨源和水源的反应，以及催化剂经过反复4次高温焙烧再生之后的反应进行了评价，该催化剂都表现出同样高的活性、选择性和稳定性。

PNA hybridizes with DNA or RNA by means of Waston Cricks base pairs complementary with high stability, affinity and selectivity. PNA not only regulates DNA replication, but also adjusts DNA transcription and translation. Many applications have been explored as a new kind of molecular biological tool and a gene targeting strategy.

肽核酸是一类人工合成的核酸类似物，PNA与核酸链以 Waston- Crick碱基配对方式稳定互补结合，具有高度的亲合性、稳定性、特异性特征，PNA能调节基因的表达作用，包括调节基因的复制、转录、翻译过程，因此 PNA有着广泛的分子生物学效应，显示出作为基因调节药物的应用潜力

UPP can degrade intraeellular proteins with high effect and selectivity, especially for cell cycle regulated proteins, oncoproteins, tumor suppressor proteins, and denaturalized proteins.

当泛素-蛋白酶体系统对靶蛋白的降解功能失常时，可以引起癌蛋白聚集、抑癌蛋白异常降解、突变细胞凋亡受阻和增殖加速，从而导致肿瘤的发生。

We would like to measure the intrinsic selectivity behavior of a catalyst independent of any potential disguises.

我们很想去掉任何可能的假象以测定催化剂固有选择性的可能。

Dialectic contains much points against science: dialectic , with simple opinion, its one dividing into two of opposite and consolidation broke nature's ordered and organic character; combing two into one being simply patched at least goes against thing's selectivity; law of the unity of opposite wrongly treats contradiction as principle, and does not deeply explore the objective principle of contradiction trending to utility; contradiction generalization dissevers the thing's utility, which denies the relativity of existence, truth, non-contradiction of rule being in relative condition and unique correctness.

辩证法就存在着诸多反科学之处：辩证法观念简单，其对立统一之一分为二打破了自然的有序有机性，而合二为一又简单拼凑，至少违反了事物的选择性原则；对立统一规律化，错误的把矛盾这一事物的状态当成了规律，而没能深入探索矛盾由对立趋向统一的客观规律；矛盾普遍化，割裂了事物的统一性，否定了存在的相对性，也否定了真理、规律在相对条件内的非矛盾性，唯一正确性；辩证矛盾核心论，乱用核心，否定了事物由低级趋向高级发展的客观规律；认识论如矛盾论，使认识等矛盾，使一切关系变成矛盾等等。

On the basis of the thermodynamic analysis, the equilibrated concentration of the components, the conversion of CO and the selectivity of DME in the different pressure and temperature have been studied. The feed gas is come from coal and natural gas.

在此基础上，研究了以煤或渣油为原料制得的合成气、以天然气为原料制得的合成气在不同压力、温度下的平衡组成、CO的平衡转化率及该操作条件下的二甲醚与甲醇的平衡选择性。

Meanwhile, the equilibrated conversion of CO and the selectivity of DME would be hemmed in the chemical equilibrium even if in agreeable reaction condition

同时，对合成气直接制二甲醚与甲醇的反应，即使是理想的反应条件，CO的平衡转化率与二甲醚的平衡选择性也要受到化学平衡的限制，不可能超越化学平衡。

We identified the most conserved sites in the GLUT1 and found out a new motif which is probably crucial for the selectivity of GLUTs for the transported sugars like QLS motif.

在GLUT1中，除已经验证QLS和QLG这两个重要的模序外，我们还发现了另外新的一个非常保守的模序，该模序的功能可能和QLS类似，是GLUT1转运葡萄糖所必须的。

The present invention belongs to the field of chemical technology, and is especially high selectivity catalyst for hydrogenating dimethyl maleate to prepare tetrahydrofuran and its preparation process.

本发明属于化工技术领域，具体是一种用于马来酸二甲酯加氢制四氢呋喃的专一选择性催化剂及其制备方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
