碱的

5Through surveying and sampling in field and analyzing the characteristics of heteroptera Kitog landscape, we can conclude the changes of hetroptera Kitag related to people's activities.

通过对翅碱蓬景观斑块的野外采样调查与格局特征分析，笔者认为，翅碱蓬的消长与人为活动有着密切的关系。

Field investigation,pot culture test and water culture experiment of Suaeda heteroptera Kitag in Panjin"Red Beach"were conducted,the results showed that the increasing salt amount of the beach soil gave the main cause for the plant Suaeda heteroptera Kitag 's withering and death.

通过对翅碱蓬的野外调查、盆栽试验、水培实验，得出滩涂土壤盐分升高是引起翅碱蓬枯萎死亡的主要原因，并提出了恢复&红海滩&生态功能切实可行的技术措施。

Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials can't resist the corrosion of strong oxidable acid.

在常温下，PVF2对卤素、卤代烃、强氧化剂、沸酸、碱等多种有机溶剂都有良好耐蚀性；UHMWPE对非氧化性酸(稀硫酸、硝酸及浓度较大的盐酸、磷酸、氢氟酸、甲酸、乙酸)、氨和胺及各种碱、盐溶液都有良好的耐蚀性，两种材料都不耐强氧化性酸的腐蚀。

I registered the company's "Dawn" licensing protopine, solid base, in the domestic market enjoyed a huge market, by the majority of users of all ages.

我公司注册的&曙光&牌片碱、固碱，在国内市场上占有巨大的市场，深受广大用户的青睐。

Methods:tlc was used by the same rf of the color for the identification,the content of uncaria alkaloid in rhynchophylline was determined by ultraviolet spectrophotometry.

采用tlc通过显色剂的显色比较有相同的rf进行鉴定；采用紫外分光光度法对钩藤总碱中的钩藤碱进行含量测定。

Rhynchophylline, a neuroprotective agent isolated from the traditional Chinese medicinal herb Uncaria rhynchophylla, was shown to affect voltage-gated K+ channel slow inactivation in mouse neuroblastoma N2A cells.

钩藤碱是从传统中国草药钩藤中，所萃取出来具有神经保护作用的成分。我们以小鼠神经母瘤细胞N2A细胞膜上的电位调控钾离子通道为实验材料，发现钩藤碱能影响Kv通道的慢性钝化过程。

Phenolic agent in alkaline lignin separated fromthe the black liquid can result in a chain etherized reaction on cycloalkanes by alkaline distilling so as to make lignin change its property.

本文对碱木素胺化改性过程中涉及的黑液提取、木素分离方法、碱木素胺化以及其作为沥青乳化剂的应用现状与发展前景等做了较为详细的综述

Petrological and geochemical characteristics of alkali-rich porphyries suggest that magmas might not be generated from subducted oceanic slab, but likely from the base of thickened crust, corresponding to eclogite-facies.

富碱斑岩产出的地质背景及岩石学和地球化学特征表明，富碱斑岩并非起源于俯冲的大洋板片，而是源于加厚地壳的底部，源区为榴辉岩相岩石。

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。
