紫外和大部分可见光区的不同波长的单色光刺激均能使3种草蛉成虫复眼产生振幅不等的ERG反应，依据ERG振幅的大小3种草蛉的光谱敏感曲线在340-605nm的波谱范围内表现为3个或4个大小不等的峰。

Functions include wave form addition, wave form subtraction, Lissajous Pattern display, transient signal recording, RMSamplitude spectrum display, relative amplitude spectrum display, phase spectrum display, auto correlation coefficient display, cross correlation coefficient display, function generation, and multi-tone generation.

功能包括音形叠加，音形结构，Lissajous Pattern 显示，暂时信号记录，RMS 声谱振幅显示，相关声谱振幅显示，自动相关系数显示，交错相关系数显示，函数生成以及多声音生成。

However, if the amplitude excessed 90%, the mounts of larger bubble increase as the increasing time.

另外，选择惰性气体SF6作为微泡内气体，设计了基于两种非离子表面活性剂（Span 60和Tween 80）的包膜超声造影微泡的膜材料组成，使用声振法制备得到表面活性剂包膜的超声造影微泡；对制备过程中的声振条件进行优化，结果表明总体上振幅越大，处理时间越长，声振后溶液的总体积增加得越多，即产生的微泡量越大，并且平均粒径越小，但当声振幅度增大到90%时，随着声振时间的延长，主要增加的是大微泡的量，有效微泡的量无明显增加，因此最佳的声振条件选择为振幅90%，声振时间60s。

The earliest change of ERG in birdshot chorioretinopathy was the prolongation of cone ERG implicit time. Followed by the decrease of dark-adapted b wave amplitude. The b wave amplitude of cone ERG decreased later. The duration of the disease correlates with the amplitude of b wave in the same patient. The a wave was the last affected and the decrease of the a wave amplitude was disproportionate compared to that of b wave, revealing a typical negative type ERG.

结果发现最早的变化为锥细胞ERG潜伏期的延长；接着是暗适应b波振幅下降，锥细胞b波下降较晚，同一患者病程的长短和ERG b波振幅下降幅度一致；a波振幅下降晚于b波，且下降不成比例，出现负相ERG，可作为诊断此疾病的特征性ERG。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.
