极性

But if under sulphurating condition the bonding layer is unstable, or suppurating craft is difficult to come true,we adopt cold bonding.

由于硫化橡胶表面的极性较弱、活性较低，并且存在脱模剂和喷霜物，因此要想把它粘合到强极性的金属表面上就必须对其进行清理和化学处理。

The results suggest that the primary sequence has the same symmetries as their tertiary structure.

氨基酸的特性，像二级结构形成的倾向性，极性和非极性残基在蛋白质序列中的位置等都在形成蛋白质的三级结构方面起着重要的作用。

The results showed that Kaidimycin was chemically neutral, macrocylic polylactones, stable and liable to dissolve into water and pyridine, slight to dissolve into methanol, ethanol and N-butanol, difficult to dissolve into ethyl acetate, acetone, benzene and chloroform. Chemical reaction of functional group of Kaidimycin showed that it had glycoside, amino acid and aldehyde, no reducing sugar, polypeptide and phenol.

The photoinduced cis-trans isomerization reaction occurs after photo-irradiation of this compound, and the rate of conversion depends strongly on the polarity of solvents used.

八 研究了C5位联有含氮茋的三芳基-2-吡唑啉化合物(TPP15)的光物理行为，发现：该化合物在不同极性溶剂中的荧光量子产率值呈倒钟形状，这与在不同极性溶剂中邻近效应的大小以及吡唑啉环和含氮芪基团间的电子转移的难易程度有关。

At last, in the absence of molecular oxygen, dehydrogenation of FMMH〓 in Photobacterium phosphoreum might be interrupted by the reaction between the Cyanide Alcohol Carbanion and Flavin monoclevtide .

以相加作用的非极性麻醉型有机化合物、极性麻醉型有机化合物和反应性化合物为研究对象，分析了各种相加作用的不同本质。

The eluent is changed in a regular manner starting with a nonpolar solvent and gradually replacing it by a more polar one.

洗脱液以常规的顺序更换，首先用非极性溶剂，然后逐步被极性较强的所替换。

In addition to setting the clock frequency, the master must also configure the clock polarity and phase with respect to the data. Freescale's SPI Block Guide [1] names these two options as CPOL and CPHA respectively, and most vendors have adopted that convention.

除了设置时钟频率，主设备同样需要设置数据传输相关的时钟极性以及相位。freescale'sSPI的手册命名这分别以cpol以及cpha来标志时钟的极性以及相位，大部分的芯片厂商采用了这种协定。

All of the three ether imides synthesized exhibited low inherent viscosity, high thermal stability of 456 to 499 oC in TGA measurement (5wt% loss/N2) with Tgs between 240 ~254 oC. They also show good solubility behaviors in N-methyl-2- pyrrolidinone, dimethyl sufloxide, dimethyl formamide, chloroform, and m-cresol.

所得聚醚亚醯胺高分子皆具如下相同之优点如：包括低固有黏度表现，其热性质上也具高隐定性，其TGA在氮气5 wt %重量损失测定可达456 ~ 499 ℃，其玻璃转移温度达240 ~ 254 ℃，在溶解度方面，它们皆可溶解於高极性有机溶剂如： NMP、DMSO、DMF，亦可溶於中极性之溶剂如CHCl3、m-cresol。

Ionomers are normally referred to ionic-polymers with non- or low polaritypolymer backbone and low ionic group content of less than 15mo1%.

离聚体是指在非极性或弱极性的主链上带有少量离子基团(通常少于15mo1％)的一类离子聚合物。

Cell polarity is the fundamental characteristics of eukaryotic cells and of crucial importance to the differentiation and functions of most cells in the metazoans.

细胞极性是真核生物的基本特征。在多细胞动物中，细胞极性在大多数细胞的分化和功能发挥中具有至关重要的作用。
