Analyze the gain spectrum of modulation instability under specific nonlinear responds. We take logarithmically nonlinear medium as an example to discuss MI gain spectrum of coherent and incoherent beams both.

一、我们在微扰近似下，分析了介质的非线性响应形式对调制非稳增益的影响，以对数型非线性介质为例分别讨论了相干光束和非相干光束的调制非稳性。

Results: This new chart overcame the shortcomings of different number of optotypes on each line and fewer optotype at the top of CSVAC. The measurements of this new chart had significant correlation and good agreement with CSVAC. And discovered the score difference between noisy and blank visual acuity chart.

结果：该视力表改变了每行之间视标个数不等的缺陷，与国家&标准对数视力表&检查结果之间具有较好的对应关系，并且可以掌握噪声视力表和无噪声视力表之间检测结果的差异。

After different concentration grades of 2,4-D were added into the vegetative green cells respectively, then H. pluvialis were cultivated under unfavorable growth conditions (24 h light cycle, 5000 Lx, 25°C, nutrition deficiency) to promote astaxanthin accumulation.

在对数生长期的藻液中分别加入一系列不同浓度的2，4-D溶液，然后进行胁迫培养(25°C、24 h、5000 Lx连续光照+营养盐饥饿)，诱导细胞内虾青素的合成积累。

Effect of extraneous salicylic acid on astaxanthin accumulation was studied in alga Haeinatoccu pluvialis. After SA was added into the vegetative green cells at a different concentration, the alga was cultivated under unfavorable conditions (24 h light cycle, 5000lx, 25℃, nutrition deficiency) for growth to promote astaxanthin accumulation.

在对数生长期的藻液中分别加入不同质量浓度的水杨酸溶液，进行胁迫培养（25℃，24h 5000 lx连续光照＋营养盐饥饿），诱导细胞内虾青素的合成积累。

Delay distortion caused by log-periodic antenna can be avoided by changing its feed ing method; Reflection can be greatly reduced by resistively loading antennas as cylindrical monopole antenna,conical monopole and TEM horn antenna, resulting in better characteristics in radiating pulse signal.

改变对数周期天线的馈电方式可以避免滞后失真；根据 WU- KING偶极子理论，对圆柱单极子天线、单圆锥天线和 TEM喇叭天线等进行加载可以有效减小反射，改善了天线辐射短脉冲的性能，但同时也导致了辐射效率的降
