The H2O2 dosage in AP treated process had evident effect on brightness of sheet. The action of alkali in AP process is to make structure of cell wall loose.

碱性过氧化氢处理 TMP长纤维组分能明显降低浆中抽出物含量，纤维表面产生大量的羧基；过氧化氢用量的变化对白度影响较为明显；碱的作用是使细胞壁结构变得松弛，随着用碱量的增加，抽出物含量明显降低，羧基含量大幅度增加，纤维表面O/C比也略有增加，各项强度均增加。2。

The impact of precommercial thinning on tree growth and stem quality in jack pine was examined.The study was based on a PCT trial established in 1966 in New Brunswick,Canada.Three thinning intensities,1.22m×1.22m,1.52m×(1.52m),2.13m×2.13m,and a control stand were studied and a total of 154 sample trees were collected from the trial.

以加拿大新布郎斯威克省自然资源与能源部1966年建立的天然林抚育间伐实验基地为研究对象，从3种疏伐强度(1.22 m×1.22 m，1.52 m×1.52 m，2.13 m×2.13 m)的样地和一块控制地中共采伐了154株树，胸径范围10~24 cm，研究抚育间伐对北美短叶松的生长及材质的影响。

One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager,and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him —— for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl —— wasting more time in delay and circumspection than would have sufficed to walk the whole distance—— I never saw one walk —— and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time —— for no reason that I could ever detect, or he himself was aware of, I suspect.

有一只赤松鼠开始谨慎地穿过矮橡树丛，跑跑停停地在雪地奔驰，像一张叶子给风的溜溜地吹了过来；一忽儿它向这个方向跑了几步，速度惊人，精力也消耗得过了份，它用"跑步"的姿态急跑，快得不可想象，似乎它是来作孤注一掷的，一忽儿它向那个方向也跑那么几步，但每一次总不超出半杆之遥；于是突然间做了一个滑稽的表情停了步，无缘无故地翻一个觔斗，仿佛全宇宙的眼睛都在看着它，——因为一只松鼠的行动，即使在森林最深最寂寞的地方，也好像舞女一样，似乎总是有观众在场的，——它在拖宕，兜圈子中，浪费了更多的时间，如果直线进行，早毕全程，——我却从没有看见过一只松鼠能泰然步行过，——然后，突然，刹那之间，它已经在一个小苍松的顶上，开足了它的发条，责骂一切假想中的观众，又像是在独白，同时又像是在向全宇宙说话，一我丝毫猜不出这是什么理由，我想，它自己也未必说得出理由来。
