In this experiment, the contents of calcium, magnesium and phosphorus in plasma, liver or muscle of the one-month-old rabbits fed by the drinking water with sodium fluoride at the 0,150 and 300mgL^(-1) for 40 days were determined.

试验中，给一月龄幼兔给予了含有浓度分别为0、150和300mgL^(-1)氟化钠的饮用水为期40d的处理，测量其肌肉、肝和血浆钙、镁和磷含量的变化。

It is used to some extent in pharmaceutical industry (used as special catalyst to produce antibiotics) and chemical industry, esp. in production of cephalosporin (whose effect is better than boron trifluoride ethyl ether complex compound), and also used for most advanced science, such as abstraction of fuel with high energy and of isotope B10 as well as chemical reagent.

在制药工业(在医药上作为生产抗生素的专用催化剂)、化学工业等行业中都有不同程度的使用，尤其在头孢抗菌药类，效果优于三氟化硼乙醚络合物，亦用于尖端科学，如高能燃料的提取及提取同位素B10，也可用作化学试剂

In addition to the multi-ring alkenyl ethers and alpha-fluorinated acrylates, additional monomers comprising one or more cyclic aliphatic and heterocyclic compounds, both unsubstituted and substituted, in particular dihydropyrans, may be incorporated into the photosensitive polymers.

除了多环烯基醚和α-氟化丙烯酸酯之外，可向所述光敏聚合物引入另外的单体，所述单体包括一种或多种未取代的和取代的环状脂肪族化合物和杂环化合物，特别是二氢吡喃。

This compact polythiophene film showed different responses to anions with different sizes dimension when it was electrochemically oxidized.

在噻吩/三氟化硼乙醚溶液中于低电位下得到的聚噻吩薄膜还具有非常致密的结构，使掺杂离子在聚合物中的输运受到了限制。
