Applying 6% organic materials + 500mg kg〓 N fertilizer, we got the result that the N content is the highest in leaf, stem and absorbing root and promoted 46%, 28%, 44% respectively compared with controls; N% increased most significantly in ligneous root and growing root of 200 and 500mg kg〓 N fertilizer, by 32% and 29% respectively.

叶、茎、吸收根N％以6％有机物料+500mg kg〓氮肥处理最大，与CK相比，分别上升了46％、28％和44％，单纯施用200和500mg kg〓氮肥的处理中木质根、生长根的N％增加最明显，分别提高了32％和29％。

The result showed that the biomass of root, stem and leaves of Quercus virginiana were reduced with the increase of salinity and the decline of dry weight of stem and leaves was greater than that of root, which indicated that the aboveground of live oak was more sensitive to salt than the underground which lead to the increase of root-shoot ratio.

结果发现，在经过不同质量质量浓度NaCl处理21d后，随着NaCl质量质量浓度的增加，弗栎植株生长受到抑制，其中茎叶生物量减少的幅度较根系大，表明弗栎地上部生长比地下部对盐胁迫更加敏感，从而导致根冠比增加。

With the lapse of breeding years, the cultivars tended to have less root, shorter root length, larger active root absorption area, and smaller diameter of metaxylem vessel of seminal roots.

For instance, it is usually accepted that there will be multiple ''root'' or ''top-level'' certificate authorities in a global PKI, not just one ''root,'' although in a local PKI there may be only one root.

例如，通常可以接受在全球性的PKI中有多个"根"或"顶级"证书授权中心，而非只是一个"根"，尽管在本地PKI中只能有一个根。

The time and frequency of the polecat searching different preys and burrows were nearly the same. The polecat attacked virtually all prey offered and thus exhibited opportunistic foraging behaviour. However, it did not captured all prey with equal sequence. It first captured the zokor, then the pika and last for the root vole. In addition to using the typical musteline killing method of biting the nape of the neck, the polecat evolved a variety of killing methods suited to a range of prey types depending on the activity, size and anti-predation ability of prey. The zokor was bitten on the head, whereas the pika was killed by bites to the head or throat and the root vole was killed by bites to the head or chest. The time polecats pursued the root vole was the longest, followed by that used in pursuing the pika and the zokor.

实验结果表明：艾虎对三种猎物的搜寻时间和搜寻频次基本一致，在搜寻猎物的过程中并非已知洞道系统中所存在的食物信息，是一种机会主义的捕食者；艾虎除了具有典型鼬科动物捕杀猎物的方法外，能够根据猎物的大小、活动性和反捕食能力采用不同的捕杀方法，在捕杀猎物的过程中首先捕杀高原鼢鼠，其致死部位全部为头部，其次捕杀高原鼠兔，其致死部位除了头部外，明显增加了颈部的比例，最后捕杀根田鼠，其致死部位主要是头部和胸部；艾虎在捕杀猎物的过程中，追击根田鼠的时间最多，追击鼢鼠的时间最少，而用于捕杀根田鼠的时间最少，用于捕杀鼢鼠的时间最多，艾虎捕杀高原鼠兔后单位时间内获得的能量值最大，其次为捕杀高原鼢鼠，而捕杀根田鼠后单位时间内活动的能量值最小。

Nabs' spousal native place is Hangzhou, 78 year-old come Beijing, treated in Beijing had more than ten years, basically already has not missed with the ordinary person from Beijing, but this Hangzhou vegetable craftsmanship but was unambiguous, but must say, the root was a root, the pole was a pole, the two matters, others root was Hangzhou, buried under the place, you could not change....
