查询词典 emission spectrum

Since the harmonic spectrum of ac-side phase voltage of PWM rectifier is influenced not only by pulse modulation style, but also by the parameters of close-loop adjustors, a three-phase voltage source inverter controlled by TMS320F2812 has been built to obtain the harmonics purely generated by SVPWM and verify the algorithm. Power analyzer PZ4000 has been adopted to acquire experimental results.

由于PWM整流器交流侧相电压的谐波频谱不仅与脉冲调制方式有关，还受到闭环调节器参数的影响，因此该文搭建了以TMS320F2812为控制核心的三相电压型逆变器系统以得到单纯由SVPWM产生的谐波频谱，并对该算法进行验证。

When the adsorbates adsorbed on the substrate, the characteristics of the surface of the substrates maybe varied, the SERS spectrum of adsorbates may be different. This makes the analyses difficult.

当分子吸附在基底上时，如果基底表面的性质发生变化，吸附物的SERS光谱也会随之发生变化，这就使得光谱的分析变得困难。

The binding energies assigned to each of these peaks is in accordance with the accepted value for these functionalities [18,28]. The O–C_O high energy binding peak may include anhydrides, esters, and carboxylic acid groups, if present. The C1s spectrum of the 40W films could be fitted with a minimum of 5 peaks according to the above notations, as shown in Fig.

装订 被指定给每一个这些峰巅的能源是符合那为这些功能性〔18，28 的一般承认的价值。O－C_O 高的能源装订山顶可能包括醋酐，酯，和含有羧基的酸聚集，如果呈现。40W 的 C1s 光谱电影可能根据配备有 5 的最小量峰巅到那在记号法上面，如图 3 A 所示。

SEM, Raman and PL spectrum were adopted to characterize the surface, structure and photoluminescence property of samples. In comparison with those prepared by anodising p type silicon, the porous silicons prepared by non-acid hydrothermal method have smooth surface, regular shape of pores and higher PL efficiencey.

实验采用扫描电镜、拉曼光谱和光致发光谱对样品表面形貌、结构及发光性能进行表征，并与用常规电化学阳极氧化法制出的多孔硅进行了对比研究，研究结果表明用无酸水热法制出的多孔硅表面平整，孔的形状规则，发光效能提高更多。
