文章摘要：在催化剂存在下，使正硅酸乙酯与乙醇-水溶液混合制备硅醇溶胶，迅速将其分别注入到西南桤木和紫椴木材中，令其在室温下反应100min左右得到木材-凝胶，然后采用超临界干燥技术制备木材-SiO2气凝胶。

Many waves are there agitated by the wind, keeping nature fresh, the spray blowing in your face, reeds and rushes waving; ducks by the hundred, all uneasy in the surf, in the raw wind, just ready to rise, and now going off with a clatter and a whistling like riggers straight for Labrador, flying against the stiff gale with reefed wings, or else circling round first, with all their paddles briskly moving, just over the surf, to reconnoitre you before they leave these parts; gulls wheeling overhead, muskrats swimming for dear life, wet and cold, with no fire to warm them by that you know of; their labored homes rising here and there like haystacks; and countless mice and moles and winged titmice along the sunny windy shore; cranberries tossed on the waves and heaving up on the beach, their little red skiffs beating about among the alders;-- such healthy natural tumult as proves the last day is not yet at hand.

那儿风大，空气清新，激流拍岸，水花四溅直朝你脸上扑来，芦苇草和灯心草迎风翻舞。成群的鸭子在巨浪狂风中不安地游向岸边，正要上岸时，随着一阵嘎嘎的叫声，纷纷散去，直奔往Labrador，有的瑟缩着翅膀逆风飞行，有的先是浮在浪头打转，快速地扑打着双蹼，打量了一眼船上的人才离去；海鸥在空中盘旋，麝鼠也奋力游着，浑身湿冷，它们可不能和人一样用火取暖，到处是它们象草堆一样垄起的房子。晴朗多风的岸边，有数不清的老鼠，鼹鼠和山雀；酸果蔓在波浪中招摇，红色的小艇摇晃穿梭在桤木丛中-----这种生机勃勃的景象说明世界末日远未来临。

杉木跟桤木混交以后，保留了纯林的大部分属性，各类群在大型土壤动物群落中的地位基本保持不变，双翅目、蜘蛛目、膜翅目仍然是最主要的类群，但这种混交方式改变了一些土壤动物的群落结构参数，多度和丰富度出现上升的趋势，均匀度显著降低。

When the water is at its height, the alders, willows, and maples send forth a mass of fibrous red roots several feet long from all sides of their stems in the water, and to the height of three or four feet from the ground, in the effort to maintain themselves; and I have known the high blueberry bushes about the shore, which commonly produce no fruit, bear an abundant crop under these circumstances.

当湖水涨得最高时，桤木，柳树和枫树从它们的淹在水里的根上伸出来大量纤维质的红根须，长达数英尺，离地有三四英尺高，想这样来保护它们自己；我还发现了，那些在岸边高处的浆果，通常是不结果实的，但在这种情况下，却就有了丰收。
