随重金属胁迫浓度的增加，水稻籽粒萌发期的Q一淀粉酶活性先上升后下降，重金属胁迫能显著抑制釉稻和杂交稻p一淀粉酶活性，但低浓度的重金属胁迫对粳稻压淀粉酶活性产生诱导作用。

The paper also introduces the ingredients of some typical nobel metal - rare earth metal catalyst.

给出了几种典型贵金属－土金属催化剂的配方。

Professional silk screen etching: stainless steel signs, letter box, mechanical panel, ti-gold signs medal, copper signs nameplate, PVC electric nameplate, metal highlight signs, brushed aluminium oxidation panel, blasting panel, acrylic show stand, acrylic medal, metal high grade name card, and VIP card.

A method for forming a passivated metal layer that preserves the properties and morphology of an underlying metal layer during subsequent exposure to oxygen-containing ambients.

本发明提供了一种形成钝化金属层的方法，所述钝化金属层可以在随后暴露于含氧环境时保持下方金属层的性质和形貌。

Anodising reaction proceeds in the sequence of growth of porous anodic alumina when the aluminum layer is consumed up to the underlying metal, and the growth of metal oxide under the bottoms of the alumina pores occurred simultaneously.

以电化学的方式在阳极产生氧化铝孔洞的同时，底层的金属同时被氧化而在孔洞底端成长出奈米点。以草酸、硫酸和磷酸不同的电解液和不同施加电压下观察奈米点的阵列。

The kinetics of reconstitution of apoacylase with either 〓 or 〓 and the inactivation of the 〓 reconstituted enzyme by 1, 10-phenanthroline has been studied by following the substrate reaction continuously in presence of the metal ion or OP respectively. Although the native 〓-containing and the 〓-reconstituted enzymes have closely similar Michaelis constants and maximal velocities, the kinetics for both the inactivation by OP and the reconstitution of the apoenzyme with the metal ions differs considerably.

虽然钴重组的氨基酰化酶与天然含锌的氨基酰化酶在催化活性上比较相近，但两种酶在去金属失活动力学机制以及去金属失活的氨基酰化酶与两种金属离子重组复活的动力学过程均存在较大的差异，说明锌在氨基酰化酶中的作用比较复杂，并不能完全由钴替代。

Said metal nitride is prepared through mixing the aqueous soltuion of nitrate or sulfate of A with the aqueous soltuion of Cr, Mo or W acid or one of their ammonium salts, coprecipitation or impregnation to obtain load-type or non-load-type dual-component metal salt or compound oxide, then pass in NH3, sequentially heating and azotizing at 600-750 deg.C.

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.
