On the presentation of Mn-P fixation, this paper reviews the latest advances in recent 10 years and concentrates on the mechanism of phosphorus fixation in acid soils. In addition, it brakes through the classical inorganic P fractionation in to Fe-P, Al-P, O-P and Ca-Pin the traditional P classification and considers Mn-P as one of the main phosphorus fixation modes in latosols, cultivated from the parent basalt material. Furthermore, fixation of P by Fe, Al, Mn is compared, and differentiation from chemical availability and bioavailability of P discussed. Based on the above, this paper presents some alienable measures for enhancing P utilization efficiency and postulates pivotal future research directions in the field of P fixation.

本文以Mn-P的提出为出发点，论述了近10年来对酸性土壤固磷机理研究的新进展，突破了常规P素形态分级研究中分为Fe-P，Al-P，O-P和Ca-P等无机磷测定的经典分级，认为玄武岩母质砖红壤中的Mn-P是P素固定的主要形式之一，进而比较了Fe、Al、Mn对P固定作用，并从P的化学有效性与生物有效性差异等方面进行了比较全面的论述，提出了减少P素固定提高磷肥利用率的措施及今后的重点研究方向。

It read:'Woody Allen says he ate at a restaurant that had O.P.S. prices—over people's salaries.' Dreadful by any standards, and thus ideal for the likes of Winchell, Ed Sullivan and Earl Wilson, whose columns ate up more material than the gypsy moth caterpillar.

上面写着：'伍迪艾伦说他曾在O.P.S价位的酒店吃饭。O.P.S-- over people's salaries' 他的专栏博采众家之长，揉进各种由于摒弃种种写作框架，思维方式与Winchell译注1， Ed Sullivan译注2 Earl Wilson译注3相似。

Halogen ion can enter and break the phosphate glass network when they exceed certain content. The short range structure of metaphosphate and polyphosphate glasses are all built with phosphate chains. Most of lead ions still act as network modifiers, and some lead ions enter glass network to form tetrahedron or Pb-O-P linear linkages.

Br〓和F〓离子达到一定浓度时就会进入网络，使得玻璃网络发生断裂。P〓O〓含量为50mol％和40mo1％的玻璃样品结构都为链状结构，一部分pb〓离子进入玻璃网络中作为网络形成体，形成四面体或Pb-O-P键：而大部分的pb〓离子仍然作为网络修饰本。

With the same final brightness about 84%ISO, O~*P pulp consumed less active chlorine and peroxide compared with the OP pulp; although O~*P pulp needed a higher beating energy,the tensile index,tear index and burst index of the pulp were better than those of OP pulp at the same ~oSR value.

当漂白浆的白度均为84%ISO左右时，与CK2 OP漂白浆相比，CK2 O~*P(O~*为表面活性剂S3强化的氧脱木素)漂白浆所消耗的漂白化学品的量更少，即氧脱木素段添加合适的表面活性剂能有效降低漂白化学品用量。
