查询词典 spectrum

In 1997, Baulieu named these steroids as "neurosteroids". In general, through the genomic and nongenomic effects within the CNS, neurosteroids exert a broad spectrum of action on neuronal function and plasticity.

一般说来，通过基因水平和非基因水平两方面途径，神经甾体调节了神经元的功能及其可塑性，在中枢神经系统中起到复杂多样的作用。

Five minutes is the optimal irradiation time for ALA-PDT by Xe lamp under the same irradiation conditions. Irradiation injury caused by the light alone was slight, but the destruction rate of ALA-PDT was very high. Conclusion: Xe lamp's action spectrum is wider and it's power is higher, so it's better than 532 nm laser for ALA-PDT.

结果：532 nm连续激光和脉冲激光对K562细胞的ALA-PDT抑制率均较低，增加光剂量也不能有效提高ALA-PDT的抑制率；氙灯在功率密度为350 mW/平方公分、光照5 min时就能达到最佳的光剂量，此时单纯光照对K562细胞的光损伤作用很小且ALA-PDT效率很高。

By analyzing, the fault transient component of third harmonic voltage at neutral is approximately equal to that at terminal. Choosing their sum and difference as the action and restrai nt signal respectively, the protection detects the ground fault by comparing the spectrum energy of action and restraint signals.

该保护方案根据单相接地故障后机端和中性点 3次谐波电压的故障暂态分量近似相同的特点，把两个故障分量的相量和与相量差分别作为保护动作信号及制动信号，通过比较数据窗内相应信号的谱能量检测定子单相接地故障。

Toosendanin pesticide is a good kind of botanical pesticide with high insecticidal activity, multiple action modes, broad spectrum and unique mechanism.

西北农林科技大学无公害农药研究服务中心结合华南农业大学毒理室的研究成果，在对川楝进行系统研究的基础上，研制开发出新型植物源杀虫剂——0。

Compare action spectrum.

比较激发光谱。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

Or by subtracting some light from the total spectrum, the result looks thesame to the eye. The additive process was employed for early color

不论某种颜色是通过把不同色彩的光线叠加还是把光谱中某些颜色的光去除掉而产生的，它的视觉效果是一样的。

The result of experiment makes clear:In the mixed system the each component height of integral in the NMR spectrum has additivity.

实验结果表明，混合体系中各组分在核磁共振图谱中的积分曲线高度也具有加和性。

氟氧头孢是新型的氧头孢烯类抗生素，具有较广的抗菌谱，对革兰氏阳性菌。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
