吸收比

Thus theoretically, weakly acidic drugs are more readily a orbed from an acid medium than are weak bases.

因此，从理论上讲，弱酸性药物在酸性介质中比弱碱性药物更易吸收。

It is worse than useless to administer to the Parkinsonian any kind of nerve tonic to 'whip up' his decaying cells; rather must some form of readily assimilable pabulum be sought, in the hope of supplying from without what the cell itself cannot obtain from within.

对於巴金森氏病施以任何细胞补药，以图刺激衰弱细胞，比无效还糟；我们更应该寻求可以立即吸收的食粮，以便从外部供应细胞无法从自身内部得到的。

Chapter 4. Due to their large specific surface area and the photogenerated electron-hole pairs under solar illumination, semiconductor NPs have been used as catalysts in the photodecomposition of organic pollutants.

第四章，半导体纳米粒子由于拥有高的比表面积，且可以吸收太阳光并且发生电子和空穴的分离，是一类高效的有机污染物光降解反应的催化剂。

The prepared powders were characterized by XRD, UV-Vis, FTIR, N_2 adsorption, Fluorescence spectroscopy, etc. N-doped TiO_2 evidently shows its absorbance shoulder shift into visible light region. Moreover, N-doping retards the transition of TiO_2 from anatase to rutile type as well as restrains the growth of the crystal size which leads to less decrease of surface area. These characteristics are considered to benefit the photoactivity of TiO_2; When all the samples were applied to the photodecomposition of Methylene Blue under visible light(λ＞400 nm), the N-doped TiO_2 show an obvious superiority when compared to the undoped TiO_2, the active hydroxyl groups are found to play a important role in this high photoactivity; When the same experiment was performed under UV light, all the samples show the consistent sequence of photoactivity as in the visible light.

通过UV-Vis、XRD、BET、IR、FL等表征手段测试表明：掺氮不仅使TiO_2的光吸收区域拓展到可见光区，而且有利于延缓TiO_2晶相的转换，从而抑止了高温煅烧下所引起的晶粒增大以及比表面积的降低，且氮源浓度越高，此现象越明显，这些特征都有利于催化剂光催化活性的提高；在主波长大于400nm的可见光催化亚甲基蓝实验当中，掺氮TiO_2的光催化活性明显优越于未掺氮样品，亚甲基蓝在90min内达到88％的脱色率。

The spatial and temporal changes of the specific absorption coefficients of phytoplankton and non-algal particles were also analyzed.

同时，建立的非色素颗粒物的比吸收系数与其浓度的指数函数模型，R2达到0.502。

The effects of injection temperature on the dispersion phase and mechanical properties of polyoxymethylene/thermoplastic polyurethane elaster blends were investigated.

研究了注塑温度对聚甲醛/热塑性聚氨酯弹性体共混物形态结构和力学性能的影响。实验结果表明，注塑温度影响POM基体相与TPU分散相的粘度比，195℃时两者粘度相当，在剪切流动过程中，TPU可在POM基体中形成条状分散相，可吸收较多的冲击能并阻止银纹的生长以及裂纹的产生，从而较大幅度提高共混物的缺口冲击强度

This research discovered that soil pondage of level terrace were less than fallow sloping filed because of crops' absorbing and using, and evaporation.

发现由于作物对梯田土壤水分的吸收利用，以及蒸发散的原因，导致水平梯田的土壤贮水量比休闲坡地小。

Larger flavonoids in Pycnogenol delay glucose absorption 190 times more potently than prescription medication acarbose, an alpha-glucosidase inhibitor.

较大的黄酮类化合物在pycnogenol延迟葡萄糖吸收190倍以上potently比处方药物阿卡波糖， 1 α-葡萄糖苷酶抑制剂。

Because POTPy and POTPyOT contain pyridine in the main chain, their conjugation length is shorter than that of POTT and POTTOT, leading to the UV and fluorescence spectra of the former are blue-shifted with respect to those of POTT and POTTOT.

POTPy及POTPyOT主链的结构内具有吡啶，导致共轭链的长度缩短，因此在吸收及萤光光谱的位置都比POTT、POTTOT还要蓝位移。

Cuprous oxide (Cu2O) is a direct band gap semiconductor with optical band gap energy of 2.0 - 2.5eV. It is a non-stoichiometric p-type semiconductor. The attractiveness of cuprous oxide as a photovoltaic materials because of its high absorption coefficient in visible regions, non-toxicity, abundantly available starting material on the earth and low cost producibility.

氧化亚铜为直接能隙P型半导体材料，是属於一种非化学计量比缺陷半导体(non stoichiometric defect semiconductor)，光学能隙值约在2.1-2.5eV之间，具有低制造成本、无毒性、起始材料在自然界中含量丰富等优点，并且在可见光范围内具有相当高的光吸收系数，因此主要的应用可用来制造太阳能电池元件。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
