磷化作用

Phosphate porous starch and PVA were cross linked by methenamine and boric acid Crystal area was serious destroyed by esterification and cross linked. 6 Biodegradation experiment was carried out with soil-burying method.

5红外光谱和X-射线衍射的结构分析表明：在改性淀粉的羟基上引入了磷酰基团，并未破坏原淀粉的基本化学结构；交联剂在改性淀粉和PVA之间形成了C-O-C化学交联键；酯化和交联反应均有较强的淀粉晶区破坏作用。

Methyle β cyclodextrin was simply synthesized, and the impacts on the solubilization of methyl parathion and carbofuran were investigated.

摘 要：研究了甲基化β环糊精的一种简单制备方法及其对甲基对硫磷和呋喃丹的增溶作用。

Free serine, threonine and phenylalanine showed similar effect. The mechanism of the effect was also discussed.

本论文还对N-磷酰化氨基酸与植物细胞膜的作用方式进行了探讨。

In this paper, the acetalization of benzylaldehyde and 1,3-propanediol in the presence of vanadium phosphorus oxide catalyst was studied.

研究了苯甲醛与1，3-丙二醇在钒磷氧催化剂作用下的缩醛化反应，考察了反应时间、醇醛比、催化剂用量、带水剂种类和用量等因素对苯甲醛1，3-丙二醇缩醛收率的影响。

The reaction between salicylic acid and dialkyl phosphite was then traced by electrospray ionozation mass spectrometry and 31P NMR.

混配高能键的形成在整个反应进程中起着非常重要的作用，导致了大部分的磷酚化试剂最终被转化成四异丙基焦磷酸酷。

All of them were labeled with [32P] orthophosphate (2.03×10^5 Bq/mL) for 2 h and then stimulated with CCK8 l0^(-7 mol/L and DMEM respectively for different time. Reactions were terminated by freezing neurons in liquid nitrogen. The 32P-labeled lysates isoelectrically focused on IPG Drystrip pH 4~7 linear gels and subsequently separated by second-dimensional SDS-PAGE.

培养乳小鼠神经元，随机分为CCK8刺激组和对照组，32P-NaH2PO4标记后分别给予CCK810^(-7 mol/L和等量无磷培养基，作用不同时间后液氮终止反应，经双向电泳、放射自显影，获得磷酸化蛋白质的电泳图谱。

Scenedesmus sp. isolated from sewage was entrapped in calcium alginate gel for tertiary treatment of the artificial wastewater.

利用固定化藻类的生物富积作用净化污水中的氮和磷，将栅藻包埋固定在褐藻酸钙凝胶胶球中，对人工污水进行深度净化。

In fact, some of organicphosphorus was easy to be mineralized and plays an important role to the supply of phosphorus.

事实上，土壤中某些有机磷是易矿化的，对土壤磷素供应起着重要的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
