A very large sample plug was introduced hydrostatically into the capillary (65 cm×50 μm i.d., effective length of 35 cm) over 80 s at a height difference of 11 cm. The working conditions for CE-FA separation are as follows: operating voltage, 10 kV; running buffer, 67 mmol/L phosphate, pH 7.4. The unbound ketoprofen concentration was directly measured from the height of the frontal peak.

This paper investigated the effects of environmental factors, such as, pH, buffer capacity, the concentration of chloride ions and the concentration of nonaggressive anions, on the crevice corrosion potential E_(cc of Type 304 stainless steel. The E_c was ascertained by galvanodynamic polarization.

本实验主要研究pH 值、缓冲容量、氯离子浓度及其缓冲溶液中其它阴离子浓度等环境因素对304 不锈钢缝隙腐蚀电位的影响，缝隙腐蚀电位由动电位扫描确定。

Human pericardia from cadaeric donors were treated sequentially with hypotonic buffer, SDS in hypotonic buffer, and a nuclease solution.

The experiment results indicate that logarithmic growth phase,resuscitative buffer Ⅴ,electrotransfection buffer Ⅳ,23kv/cm and 200 resistance are regarded the best electrotransfection condition of Sinorhizobium meliloti.

结果表明细胞的对数生长初期、复苏缓冲液Ⅴ、电转缓冲液Ⅳ、23 kv/cm和200Ω适合作为苜蓿中华根瘤菌电转的条件。

In order to investigate the electrotransformation condition of Sinorhizobium meliloti variable curve was devised by different cell cycles time,resuscitative buffer,electrotransfection buffer,pulsed electric field and resistance.

为了研究苜蓿中华根瘤菌电转化的条件，通过对不同的细胞生长周期、复苏缓冲液、电转缓冲液、电场强度和电阻对电转率影响程度来作出变化曲线，以确定电转化的最优条件，从而提高苜蓿中华根瘤菌电转化率。

Commercial manufacturers will often use a low-molarity buffer so that the consumer can easily resuspend the conjugate in the buffer of his or her choice. Generally, high-salt buffers and surfactants should be omitted from the final storage buffer as they may cause damage by hydrolysis or displacement of the antibody.

最终储存用的缓冲液应避免使用高盐缓冲液和表面活性剂，因为它们可能水解或取代抗体。
