同时遮荫还改变物质运输分配到各器官的比例。

Objective: To study the effect of changing source-sink ratio on dry matter accumulation yield,distribution and interrelated physiological index of Cynanchum bungei .

中文摘要：目的：研究人为改变白首乌源库比后对产量、干物质积累及相关生理指标的影响。

The overseas trade was the most energetic economic growing part in the coastal regions, stimulated and promoted the developing course of the other interrelated economic parts. For instance, the commercialized agriculture was increasingly related to the overseas market; some of handicraft industries were growingly orientated by exportation. A good deal of inflow of silver aroused the great reforms in the currency economy and the tax institution. Trade increased wealth; the increasing wealth drove the traders for more benefits, created a sumptuous atmosphere, and changed the behavior manners and merit criteria as well. In a word, the coastal regions presented unprecedented energy and prosperity.Ⅴ.

明中后期国内社会经济为海外贸易的发展提供雄厚的物质支持，贸易同样给广东、福建等地带来重大的物质利益和财富来源，为沿海平民提供了就业机会和谋生途径；对外贸易是沿海地区最有活力的经济增长点，刺激并带动相关经济部门的发展进程；例如珠江三角洲等地农业商品化生产与海外市场联系日趋密切；部分手工业生产部门出现出口导向倾向，白银的大量输入引发了货币经济和赋役制度的重大变革，通商贸易增加了财富，而财富的增加又滋长了商贩逐利、竞尚奢华之风，部分改变了人们的行为方式与价值取向，沿海地区经济呈现出前所未有的活力与繁荣。

Preparation intended to be placed in contact with the various external parts of the human body (epidermis, hair system, nails, lips and external genital organs) or with the teeth and the mucous membranes of the oral cavity with a view exclusively or mainly to cleaning them, perfuming them, changing their appearance and, or correcting body odours and, or protecting them or keeping them in good condition

化妆品包括任何一种用于人体外部各个地方的物质(表皮，毛发，指甲，唇及生殖器外部)或牙齿，口腔黏膜，用于清洁的，使之变香的，改变其外观的，或者是改变身体气味的，或是使之处于良好状态的。

The research suggested that American white oak is the best choice for the production of grape wine with strong oak aroma and European oak is the best choice for the production of grape wine with harmonious oak aroma, fruit aroma and wine aroma; air drying process of barrel plates would influence the content of total phenol, tannin and volatile substances including vanillin and MOL; and baking intensity will change original content of chemical compositions in oak and make oak barrel possess different aroma characteristics and phenol substance content.

研究表明，酿制橡木香较浓郁的葡萄酒选用美国白栎较好，酿造像木香、果香、酒香协调的葡萄酒则选择欧洲橡木较适宜；板材风干过程对橡木板材中的总酚、单宁含量及挥发性香气物质香兰素和橡木内酯的含量均有影响；烘烤强度可改变橡木木材原有的化学组分含量，使橡木桶具有不同的呈香特性和酚类物质含量。

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
