Aiming at these factors,our main ameliorative measures are:as following:adopting " three-high rates " composition,in a specific way,three rates should choose KH:0.88-0.92,SM:2.6-2.8,IM:1.6-1.8,and controlling the content of R2O,SO3,this method can insure that the content of silicate mineral is higher than 77%,especially the content of C3S is lower than 55%,so it can compensate for insufficient of descending of cement strength resulted by inactive component after implementing the checking method of ISO cement strength.

针对这些因素的主要改进措施为：采用&三高&配方，即三率值宜选择为KH0.88～0.92、SM2.6～2.8、IM1.6～1.8，并控制好R_2O、SO_3含量，以此保证水泥中的活性组分即硅酸盐矿物的含量≥77％，特别是C_3S含量不能低于55％，这样就能弥补因实施ISO强度检验方法后，水泥中非活性组分导致强度下降的不足。

The relevant experiments illustrates A.C. power is more suitable for deicing or snow-melting than D.C. Silica fume can improve the dispersion of carbon fibers and then reduce the electrical resistivity of carbon fiber cementious composites. At a certain volume content, when the ratio of cement, sand and stone is l:l:2, the properties of the CFRC is the best on the whole.

大量实验研究发现：采用交流电是碳纤维导电混凝土用于融雪化冰时的最佳电源选择；采用硅灰能较好地提高碳纤维在基体中的分散性，有效降低碳纤维水泥基复合材料的电阻率；并在现有的级配比实验中发现了具有最好综合性能的配比，即在相同的纤维体积含量的情况下，导电混凝土的具有最好综合性能的配比是水泥、砂子、石子的重量比为1：1：2。

Compatibility of cement and pfa with plasticizer was studied through the slump test of concrete from the aspects of cement, pfa and plasticizer.

通过混凝土坍落度试验，从水泥、粉煤灰及塑化剂三方面研究了水泥及粉煤灰与塑化剂的适应性问题。

Vertical pipe extrusion machine is a powder, slag, sand, cement raw material production for a long 1000mm, diameter 150-1000mm of cluster i, flat-mouth tender jack, flower tube wells and other non-reinforced cement pipe.

In order to enhance the strength of cement road surface and adapt the severe weather of westward area,concrete performance tests of adding slag in ordinary concrete were carried.

为提高水泥路面强度和耐久性以适应西部地区的恶劣天气，进行了在普通水泥砼中掺入矿渣掺和料的砼性能试验。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
