According to depositions of nanostructured silica in plants and chemically synthesized nanostructured silica sprayed into leaves and physical properties of leaf conferred by silica depositions as well, the first step reaction of high-specific supramolecular recognition process of fungi spores and host surfaces is discussed. Nanostructured silica can alter leaf physical properties including topography and hydrophobicity and affect extracellular matrix release and formations of germ tube, appressorium and penetration peg.

初步揭示了纳米结构SiO〓与植物真菌病害发生的关系：从化学合成的纳米结构SiO〓在叶表的沉积以及沉积之后赋予植物叶片独特的物理学特性入手，详细研究了纳米结构SiO〓抑止真菌孢子和寄主表面的高度专一性的超分子识别过程的第一步反应，从而提出纳米结构SiO〓可能改变植物叶表面原有的拓扑结构和疏水等物理学特性，即形成特殊的双亲性表面，影响真菌胞外物质的释放和芽管、附着胞及侵染钉的形成，阻断真菌孢子早期的侵染过程，从而确定靶向的真菌病害的控制措施。

The results of experiment show that separate addition of mineral admixture (ground fly ash, slag fines, silica fume) into concrete can improve its resistance to chloride ion penetration and diffusion.

从机理上分析，矿物掺合料的火山灰效应改善了混凝土中水泥石与集料之间的薄弱界面，降低孔隙率，使孔细化，同时生成更多低碱度的C-S-H凝胶增加混凝土的Cl-固化能力，从而提高了混凝土抗氯离子渗透能力。

And the fourth layer is a steel plate intended to guard against bullet penetration.

第四层是钢板，用来防子弹的。

Similarly, extrudate containing gum and citric acid exhibited increased solubility and swelling due to increased hydrolysis by citric acid which resulted in open structure that allowed rapid water penetration, swelling and solubility.

类似的，含有胶和柠檬酸的挤出物具有较好的溶胀性和溶解性也归因于柠檬酸的水作用，这种水解作用导致了结构的松散使水能很快渗透从而溶胀和溶解。

Derived from the 1929 fortress gun (itself a development of the old 1897 field gun) with a semi-automatic breech and an automatic loader added, the "high power" APX 75mm gun fired a mle 1915 HE round with a reduced charge at 400 m/s and the mle 1915 AP round at 570 m/s (50mm penetration at 1000 m) and its two sights and stereoscopic rangefinder allowed a direct fire range of 2000 m.

&大威力&APX型75毫米炮由1929型要塞炮（旧式1897型野炮的发展型）衍生而来，加装了半自动炮尾和一个自动装填器，发射减装药的1915型高爆弹（初速400米/秒），及1915型穿甲弹（初速570米/秒，1000米距离可穿透50毫米装甲）。

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。
