磷酸

The results suggest that CHBr3 is likely to intercalate into ctDNA and such intercalations mainly depend on the relative binding affinity of a metal ion to the bases and to the phosphate groups in DNA.

据此推断，CHBr3可能主要是通过嵌插作用与ctDNA碱基结合，金属离子对CHBr3与ctDNA结合的影响主要取决于金属离子与DNA的碱基和磷酸基团间结合的相对亲和比。

However,the removal of soil noncrystalline aluminum with DCB soultioncaused an obvious decrease of soil SSA.3.The hydroxy aluminum in the interlayer of 1.4nm intergrade mineralhad an important negative effect on the cation exchange capacity ofsoil colloids.Its removal would cause a significant increase in CEC valuesof the soil colloids.4.Free aluminum was the major carrier of phosphate adsorption of soilcolloids.Particularly,the active aluminum had a decisive effect on thecapacity of phosphate adsorption of soil colliods.5.Addition to the effects of other soil constituents on soil surfaceproperties,it was thought that the effect of soil free aluminum,especially active aluminum on soil surface properties,deserved closeattention.

焦磷酸钠、草酸铵、DCB、柠檬酸钠和NaOH提取的土壤铝对提高土壤CECv、AEC、PZC和PZNC起重要作用，尤以活性铝的作用较大。2）用草酸铵处理除去铝后，土壤比表面积变化不大或略有增加；用DCB处理除去土壤铝后，土壤SSA明显降低。3）层间羟基铝对土壤胶体的阳离子交换量有显著负贡献，用柠檬酸钠将之除去后，土壤胶体的阳离子交换量明显增加。4）土壤胶体中的游离铝是土壤胶体吸附磷的主要载体，尤其是其中的活性铝，对土壤胶体的磷吸附能力起决定性作用。5）除其它土壤组分对土壤表面性质的影响外，土壤中的游离铝、尤其是活性铝对土壤有关表面性质的影响，值得引起特别的重视。

Here, we tested a hypothesis that PKC-mediated phosphorylation of NET is required for transporter internalization.

在这里，我们检验了PKC介导的NET磷酸化作用对载体的内化是必须的假设。

On postnatal Day 5, wild-type mice and mice lacking alpha2A-adrenoceptor (alpha2A-KO) or alpha2C-adrenoceptor subtypes (alpha2C-KO) were randomly assigned to receive dexmedetomidine (3 microg/kg) or phosphate-buffered saline intraperitoneally. Thirty minutes after the intraperitoneal injection, the glutamatergic agonist ibotenate (10 microg) was intracerebrally injected, producing transcortical necrosis and white matter lesions that mimic perinatal human hypoxic-like lesions.

将出生后5天的野生型大鼠和缺乏α2A(α2A-KO)或α2C(α2C-KO)肾上腺受体亚型的大鼠腹膜内随机注射右旋美托咪啶(3 μg/kg)或磷酸钠缓冲液。30分钟后，脑内注射10μg 谷氨酸激动剂 ibotenate ，产生类似围产期缺氧性皮质坏死和白质损伤。

During the secondary wall formation of fiber, H+-ATPase, Ca2+-ATPase and APase also sustainablely remained in plasma membrane, plasma membrane invagination, plasmodesmata, transfer vesicles and agglutinated nucleus.

在次生壁形成的整个过程中，ATP酶、Ca2+-ATPase和酸性磷酸酶在运输小泡、细胞膜、质膜内陷、胞间连丝和凝聚的染色质中将持续存在。

Invertase activity and phosphatase activity were improved significantly.

对转化酶活性和三种磷酸酶的活性都有显著的提高作用。

The activities of soil urease, acid phosphatase and invertase were higher in aerobic treatment.

好气处理的土壤脲酶、酸性磷酸酶、转化酶活性较高。

The activities of soil catalase, alkaline phosphatase, dehydrogenase and invertase were degressive along with soil depth.

土壤过氧化氢酶、碱性磷酸酶、脱氢酶、转化酶随着土壤深度的加深呈现递减的规律。

The activities of catalase, alkaline phosphatase, dehydrogenase and invertase showed some differences in the soil profiles, but there was no difference about catalase activity.

过氧化氢酶、碱性磷酸酶、脱氢酶、转化酶的活性在土壤剖面均表现出一定的差异性，仅过氧化氢酶活性没有差异。

OBJECTIVE To determine the stability of PCS by means of ion-pair chromatography.
