冰冻线

We also got STM images of denatured fibroin under stress or by methanolin molecular level. We found the conformation of silk fibroin is changed from α-helixand random coil structures to β-strand and loosed α-helix formation. We employed the STM to explore the structure and morphology of silk fibroinin the middle silk gland of mature silkworm.

我们在分子水平上对在冰冻和甲醇处理下的丝心蛋白的变性情况进行了STM研究，我们发现丝心蛋白的构象由α-螺旋结构和无规线团的结构向β-伸展链和松散折叠α-螺旋结构转变我们还用STM对熟蚕的中部丝腺体中的丝心蛋白的结构形态进行了研究。

Be on the depth of burial time, then respond mostly take pipeline and frost line ppm compartment "relation, whereas pipeline personal property, at pipe network mesne action and exogenous factors wait here again ascertain pipeline and frost line relation" some kind of factor as well into

在冰冻地区确定给水管道的埋深时，则应主要考虑管道与冰冻线之间的关系，而管道自身的性质、在管网中的作用以及外部因素等又是确定管道与冰冻线关系的几种因素。

Gradually in the works such as Dug Rivers, Flurry, the Period of Freezing, the Scenery in the fall, the past images are disintegrated by the free and strong scrapes, the sharp diagonals and wiry beelines segment, unite the space of them.

逐渐地，在《开江》、《小雪》、《冰冻时期》、《秋日风景》等作品中，以往的意象被直率、劲力的刮痕瓦解，锐利的斜线、尖细的直线分割并统一着空间，光、线、色、形都以更加主观的内在化运动，在其刮刀下展现出丰富的张力与美感。

To prevent damage from repeated freeze-thaw cycles, the bottom of the foundation must be below the frost line.

为了防止反复冰冻解冻循环的损害，地基的底部必须在霜线以下(此处的土壤不受地表冰冻的影响)。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
