Bulk rock chemistry of Hujialing garnet clinopyroxenite in Rizhao of the Sulu ultrahigh-pressure metamorphic belt is rich in fusible composition and low in refractory composition when compared with that of the primary mantle. Whole rock has 44.04%~50.50% SiO2, high MgO(12.77%~18.73%), high GaO/Al2O3 (1.6~8.0), low alkali and Mg(superscript #)(74.82~86.13), which shows that the rock has an affinity to alumina-depleted komatiite.

与原始地幔相比，苏鲁超高压变质带的日照胡家岭石榴单辉辉石岩体全岩化学成分易熔组分均较高，而难熔组分均较低，全岩的SiO2含量为44.04%~50.50%，高MgO(12.77%~18.73%)，高CaO/Al2O3(1.6~8.0)，低碱，Mg的变化范围为74.82~86.13，成分特点类似铝亏损型科马提岩。

Considering the slope features, location of the tower, size and quantity of potential unstable rock mass on the slope surface, and the size and quantity of the rock blocks at the slope toe, a feasible risk assessment method is put forward based on the energy of the rolling rock block reaching the tower, and the frequency of rockfalls.

从影响滚石击中塔体时的能量以及塔体被滚石击中的可能性出发，提出现场评价危岩对塔体威胁等级的方法。该方法考虑了边坡形状、塔位与山体的相对位置、坡上危岩的数量和大小以及坡脚滚石的数量和大小等因素。

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。
