There were two primary differences between B. gymnorrhiza, a salt excluder and A. corniculatum, a salt exceter: one was that A. corniculatum had higher S〓 than B. gymnorrhiza, and supplemental CaCl〓 in culture solution increased S〓 of A. corniculatum more significant than that of B. gymnorrhiza.

Four white-rot fungi, Pleurotus eryngii, Polyporus versicolor, Pleurotus ostreatus and Fomes lignosus, are tested for their abilities to produce lignin peroxidase, manganese peroxidase and laccase in N-limited and N-rich media with shake culture. The four white-rot fungi only produce manganese peroxidase and laccase. Pleurotus eryngii and Pleurotus ostreatus are selected, due to their high enzyme activities, for the degradation and decolorization of alkali lignin.

Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop; such as the black birch, of which we have some handsome specimens two feet in diameter; its cousin, the yellow birch, with its loose golden vest, perfumed like the first; the beech, which has so neat a bole and beautifully lichen-painted, perfect in all its details, of which, excepting scattered specimens, I know but one small grove of sizable trees left in the township, supposed by some to have been planted by the pigeons that were once baited with beechnuts near by; it is worth the while to see the silver grain sparkle when you split this wood; the bass; the hornbeam; the Celtis occidentalis, or false elm, of which we have but one well-grown;some taller mast of a pine, a shingle tree, or a more perfect hemlock than usual, standing like a pagoda in the midst of the woods; and many others I could mention.

我并没有去访问哪个学者，我访问了一棵棵树，访问了在附近一带也是稀有的林木，它们或远远地耸立在牧场的中央，或长在森林、沼泽的深处，或在小山的顶上；譬如黑桦木，我就看到一些好标本，直径有两英尺：还有它们的表亲黄桦木，宽弛地穿着金袍，像前述的那种一样地散发香味，又如山毛榉，有这样清洁的树干，美丽地绘着苔藓之色，处处美妙呵，除了一些散在各地的样本，在这乡镇一带，我只知道有一个这样的小小的林子，树身已相当大了，据说还是一些被附近山毛榉的果实吸引来的鸽子播下的种子；当你劈开树木的时候，银色的细粒网闪发光，真值得鉴赏；还有，椴树，角树；还有学名为Celtis occidenta lis的假榆树，那就只有一棵是长得好的；还有，可以作挺拔的桅杆用的高高的松树，以及作木瓦用的树；还有比一般松树更美妙的我们的铁杉，像一座宝塔一样矗立在森林中；还有我能提出的许多别的树。

The induction of xylanase activity is dependent on inducer concentration and is not fully repressible by glucose and starch.

木糖在低浓度下具有诱导WL-11木聚糖酶生物合成的作用，但高浓度木糖则表现出一定的代谢终产物抑制效应。

The effect of the angle on the basic density of the reaction wood: The basic density of poplars and pines in the reaction wood area are both larger than the opposite wood area in different angles.

倾斜角度对应力木基本密度的影响：不同倾斜角度下杨树、火炬松应力木区基本密度均大于对应木区基本密度。

The generic distributions in both modern and fossil times were outlined, and their distribution center, place and time of origin and the way of dispersal were discussed. An attempt was made to discuss early differentiation, geographical radiation and morphological evolution of the family on the background of paleogeography and paleoclimatology, tracing back as far as the Late Cretaceous and Early Tertiary.

作者试图回到遥远的晚白垩纪和旱第三纪，从描绘桦木科植物起源和早期分化的古地理和古气候背景入手，分析了在这种背景下桦木科植物所发生的空间辐射以及植物体本身所产生的形态进化，以求得对桦木科植物起源、散布和分化作出比较合理的解释。

"Sen Yung-fu on the floor," one of the Department of the company's main brand, to focus on the floor of the development, production and sales, management products include: solid wood flooring, parquet, and strengthen the floor, ecology and so on the floor.

In view of the above factors, to a certain extent, affected the greenhouses of the application and promotion, plus the current bamboo, wood steel prices rising, the vast rural areas in urgent need of a low-cost, corrosion-resistant, resistant to moisture, anti-aging a new framework to shed Instead of the traditional bamboo, wood, steel materials, in the light of this, I units commissioned by the relevant departments, research institutions and the parties concerned under the guidance of experts, completed a "no-pillar greenhouses skeleton of" key project, supported by aircraft I developed a special formula units, the production of greenhouse skeleton without pillars of quality and cheap, quality higher than that of a steel frame, lower than the cost of bamboo, wood, the technical supervision departments test, the main performance indicators are as follows: the simulation of the actual scope: 5.8 - 6.8KN bending strength ≥ 3.3 KN compressive strength ≥ 20 KN water absorption ≤ 13

鉴于上述因素，在一定程度上影响了塑料大棚的应用与推广，又加之目前竹、木钢材价格不断上涨，现广大农村急需一种价格低廉、抗腐蚀、耐潮湿、抗老化的新型大棚骨架来代替传统的竹、木、钢材料，鉴于此，我单位受有关部门委托，在各方科研机构及有关专家的指导下，完成了《无支柱塑料大棚骨架机》的攻关项目，该机配以我单位研制的特殊配方、工艺生产的无支柱大棚骨架质优价廉，质量高于钢架，成本低于竹、木，经技术监督部门测试，主要性能指标如下：模拟实际受力范围：5.8-6.8KN 抗折强度≥3.3KN 抗压强度≥20KN 吸水率≤13

The result indicated that both woods of feedstock size of 2×2×10 cm^3 had the highest yields of wood charcoals and vinegars. At the same pyrolytic conditions, the C. japonica had higher heating value of charcoal, yield and soluble tar content of wood vinegar than A. confusa. While, the yield of charcoal, pH value, specific gravity, and organic acid content of wood vinegar of A.
