This paper summarized the characters and acting principles as well as the application of low temperature plasma technology on the surface modification of protein biomaterials, and forecasted their applied prospects. Especially it make mention of improved absorption and combination of chrome in leather processing by low temperature plasma on the surface modification of collagen fibrils, that it may come into being a new technology of free-chrome.

概述了低温等离子体的特点和作用原理，并总结了低温等离子体技术在蛋白类生物材料表面改性中应用，展望了该技术的应用前景，特别指出了通过低温等离子体对皮胶原纤维的改性处理，有望提高铬的吸收与结合，甚至实现无铬鞣制新技术，这将对传统铬鞣工艺产生重要作用。

Forest management system which provides for the removal of all merchantable trees down to a specific diameter at breast height in a single operation, followed by a poison - girdling of remaining large noncommercial stems.

指一种森林管理制度，其做法是一次性去除一切可销售的树木直至只剩下具有一定直径齐胸高的树木，接着使用毒化方法对剩下的无商业价值的大树进行环状剥皮加以剔除。

The changes in size, shape, absorption, and binding energy of Ag nanoparticles irradiated with picosecond laser of 800 nm were studied.

通过射频磁控溅射方法制备了嵌入在无定型氧化钛基体中的Ag纳米颗粒膜，研究了Ag纳米颗粒的大小、形状、吸收光谱及Ag的结合能在800 nm皮秒激光照射后的变化规律。

Discussions are made on dust-free collection of reducing slag site of magnesium production with Pidgeon process and on process of making aerated concrete block taking magnesium reducing slag as main raw material.

探讨了"皮江法"炼镁的还原渣现场无粉尘收集和以镁还原渣为主要原材料生产加气混凝土砌块的工艺，采用该工艺生产的加气混凝土砌块性能符合GB 11969—1997《蒸压加气混凝土砌块》的要求。

It indicates that the different parts of the cattle-egg stone samples in different colours all mainly compose of pyrophyllite, coexisted by two kinds of polytype of monoclinic and triclinic pyrophyllite, and the average crystal structural formula is Al4.04 Si7.89 Al0.11O204. The aggregation of pyrophyllite arranges with no direction, and the crystal size of the single pyrophyllite crystal in the weathering skin is a little bigger than that in the basal part.

结果表明，不同颜色牛蛋石样品的不同部位皆以叶腊石为主要成分，并以叶腊石的单斜和三斜两种多型共存，其平均晶体结构化学式为Al4.04[Si7.89Al0.11O20]4；其叶腊石集合体呈无定向排列，风化皮中叶腊石单晶的粒度略大于基体中的。

The study concluded:(1)three-dose IM revaccination could keep protective antibody and more importantly immunologic memory for a long time and play an important role for prevention from HBV infection in non-responders, though its efficacy could not reach the level of primary vaccination in responders;(2)although low-dose ID revaccination could induce a high proportion of non-responders to respond to vaccine, its long-term efficacy was significantly poor compared with IM revaccination with the same number of injections.

结果证实：无应答者3针常规剂量肌肉复种远期效果虽然达不到应答者初种的水平，但确能有效维持保护水平抗体、特别是免疫记忆的长期存在，在预防HBV感染方面能发挥重要的免疫保护作用；小剂量皮内复种虽能诱导高的抗体应答率，但远期效果明显不如相同针次常规剂量肌肉复种。

After the Renaissance, the newly revived inhabitants of Europe developed a burgeoning interest in collecting those ancient objects associated with the miracles and the unforgettable stories of the past. In 1580, the unlettered obelisk that stands in St. Peter's Square in the Vatican was dubbed the "Magnificent Feat".

文艺复兴后重新复苏的欧洲人，对古代文明许多奇迹和难以忘怀的故事，萌发收寻古物的强烈欲望，1580年，竖立安置在梵蒂冈圣皮埃尔广场著名的无字方尖碑被称之为壮举。19世纪，古典埃及方尖碑作为外交礼品耸立在巴黎、纽约和伦敦。

Seeds uniseriate, wingless, oblong, ovoid, or ellipsoid, plump; seed coat smooth, reticulate, rugose, or striate, mucilaginous or not when wetted; cotyledons accumbent or rarely incumbent.

单列的种子，无翅，长圆形，卵球形，或椭圆形，肥厚；平滑，网状的种皮，具皱纹，或不，被弄湿的具条纹，黏或；子叶依着的或很少现任。
