positive wave

Fluorescent ternary diagram and synchronous fluorescence spectrum can properly indicate the direction of the micro migration: from deep strata to surface, R 320 increases,λ 360 nm decreases and every wave band possesses positive gradient with the exception of λ 430 nm

荧光光谱三元图和同步荧光图谱能较好地指示微运移的方向：自深层到地表，λ320nm增加，λ360nm减小；除λ430nm外，各波段均具正向梯度

To the twenty-first century, the green wave sweeping the global ecological, in the pursuit of eco-century, China Ecological disciplines is also a positive construction.

进入二十一世纪，绿色的生态浪潮席卷着全球，在这个追求生态的世纪中，中国的生态学科也正在积极的建设当中。

Positive result are obtained with introduction of anti-interference measures against interference sources such as system harmonics, phase deviation of PT and digital wave distortion.

针对MOA检测中的干扰方式如系统谐波、PT相移以及数字波形失真提出了相应的抗干扰措施，取得了一定的效果。

The polarographic catalytic wave of rhodium(ⅲ) with 2 ( 5 bromo 2 pyridylazo) 5 dimethylamino aminobenzene ( 5 Br PADMA) in the presence of positive ion surfactant, tetrabutylammonium bromide ( TBAB) is described.

报道在阳离子表面活性剂四丁基溴化铵（TBAB）存在下，铑（Ⅲ）-2-（5-溴-2-吡啶偶氮）-5-二甲氨基苯胺体系的极谱催化波。

The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.

概率最高的地方是沿着x轴，这意味着只要在x，大于零的地方波函数都是正的。
