And used the double wave length thin layer scanning method to determine the uneven pillar tartaric acid in to puncture in the root ontent.

化学成分研究方面文献报道极少：据报道，山刺玫根中含有内酯、鞣质、还原糖、总苷、黄酮、酚类、生物碱类、蛋白质、蒽醌等成分，而且山刺玫根中总多糖是由果糖组成的均多糖。1999年，首次从刺玫根的乙醇提取物中分离出齐墩果酸，并采用双波长薄层扫描法测定了齐墩果酸在刺玫根中的含量。

The feeble fingers were never idle,and one of her pleasures was to make little things for the school children daily passing to and fro, to drop a pair of mittens from her window for a pair of purple hands, a needlebook for some small mother of many dolls, penwipers for young penmen toiling through forests of pothooks, scrapbooks for picture-loving eyes, and all manner of pleasant devices,till the reluctant climbers of the ladder of learning found their way strewn with flower, as it were, and came to regard the gentle giver as a sort of fairy godmother, who sat above there, and showered down gifts miraculously suited to their tastes and needs.

她那虚弱的手指从未有闲着，她的乐事之一便是为每天从屋旁经过的学童们制作小东西－－在窗口放一双手套，这是为冻紫的手准备的；放个针线包，给某位拥有许多玩具娃娃的小母亲；放一些拭笔布，给那些在歪七竖八的笔划丛林里辛勤劳作的小书法家们；放一些剪贴薄，给那些喜欢画画的孩子们；还有各种各样令人愉快的小玩意，直到那些极不情愿攀登学问阶梯的孩子们发现，他们前进的道路上布满了鲜花。这时他们把那亲切的馈赠者看作是童话中的仙女。她坐在那上边的屋子里，给他们抛投各种奇迹般契合他们品味和需要的礼物。

As a pole warms up in the spring, frozen CO2 on the surface thins, perforates, and begins to vent gaseous CO2 held underneath.

在春季时，极区温度上升，表面的乾冰变薄、穿孔、并开始喷出下方的二氧化碳气体。

The use of thin seam annealing furnace hoop-shaped composite structure, in large containers, weld any combination, dismantling, and transportation convenience, temperature uniformity, excellent insulation effect, heat losses small, can really achieve the elimination of welding seam annealing stress effect.

该焊缝退火炉采用薄箍形组合结构，可在大型容器的焊缝处任意组合，拆卸、运输方便，温度均匀，保温效果极佳，热损失小，真正能够达到焊缝退火消除焊接应力的效果。

The comparison and analysis of the thickness of leaf, spongy and palisade parenchyma were used to investigate the correlations of transplanting date with maturity.

研究结果表明：移栽期对于叶片解剖结构的影响很大。3个移栽期相比，5月1日移栽的烤烟中部叶片厚度、栅栏组织、海绵组织、细胞空隙度最大，各部位叶片差异达极显著水平；5月10日和5月20日的烤烟下部叶最厚，叶片厚度随叶位的上升而变薄，各部位之间差异不显著。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
