根

Ah! I have penetrated to those meadows on the morning of many a first spring day, jumping from hummock to hummock, from willow root to willow root, when the wild river valley and the woods were bathed in so pure and bright a light as would have waked the dead, if they had been slumbering in their graves, as some suppose.

啊！我在许多早春的黎明深入过这些个草地，从一个小丘跳到另一个小丘，从一枝柳树的根，到达另一枝柳树的根，当时野性的河谷和森林都沐浴在这样纯净、这样璀璨的光芒中，如果死者真像人家设想过的，都不过在坟墓中睡着了觉，那他们都会给唤醒过来的。

Results The content of Hup A in the stem and leaf is richer than that in the root.

结果 Hup A在根、茎、叶中的含量煤戏、叶＞根；贵州、广东和安徽产地的Hup A含量分别为0.018%，0.021%，0.020%，提取方法之间差异不显著。

After EA treatment, Schwann cells hyperplasia, hyperfunction peripheral vascular increase expansion in area of nerve root injury is the base of EA inhibite the process of injury nerve root demyelinate and axon degeneration, improve never repair.

电针治疗后，神经根损伤区Schwann细胞增生、功能活跃，周围毛细血管增多扩张，是电针抑制受损神经根脱髓鞘和轴突变性进程、促进神经纤维再生修复的基础。

Each root gives a reflection with respect to its hyperplane.

每个根沿著它自己的超平面又可导出一个根反射。

According to analysis of roots locus,fast excitation tends to decrease damping of power systems which is controlled by AVR than slow excitation.But eigenvalues of power system are far from imaginary axis and strong damping is obtained when fast excitation system is added.

在高放大倍数的AVR控制下，快速励磁较慢速励磁更容易恶化系统阻尼；但是在同时附加励磁控制的情况下，快速励磁可使系统的机电模式根轨迹远离虚轴，机电模式阻尼较大；而慢速励磁下，系统机电模式根轨迹接近虚轴，机电模式阻尼较小，快速励磁优于慢速励磁。

As to the given element is a imaginary root vector there are less result mainly because the structure of imaginary root space and the kac-Moody algebras are not clear.

但是对于预先给定的元素是虚根向量的情况，由于虚根空间以及代数的结构尚不清楚，难度很大，目前没有任何结果。

There are three categories of maturity indicators of organic matter in current petroleum industry to evaluate the degree of thermal evolution for source rocks, including: 1 optical indicators, i.e., vitrinite reflectance, bitumen reflectance, sporopollen color and thermal alteration index, conodont color alteration index, and reflectance of fossil fragments; 2 chemical indicators, i.e., the maximum temperature in pyrolysis of organic matter, methyl phenanthrene indicator, the atomic ratio of H/C, carbon isotope indicator, and biomarker indicators; 3 indicators of spectroscopy, i.e., the free radical concentration of kerogen, the average structural scale of aromatic nucleus of kerogen, and the laser-Raman spectrum of organic carbon.

摘 要：当前常用的有机质成熟度指标包括3大类：1 光学指标，包括镜质体反射率、沥青反射率、孢粉颜色、热变指数(thermal alteration index， TAI)、牙形石色变指数(color alteration index， CAI)和生物碎屑反射率；2 化学指标，包括有机质最大热解峰温度、甲基菲指数(methyl phenanthrene indicator， MPI)、H/C原子比值、碳同位素指标和生物标志物指标；3 谱学指标，包括干酪根的自由基浓度、干酪根芳核平均结构尺寸和有机碳激光拉曼光谱。

This single Stick, which you now behold ingloriously lying in that neglected corner, I once knew in a Flourishing State in A Forest, it was full of Sap, ful l of Leaves, and full of Boughs; but now, in vain does the busie Art of Man pret end to Vye with Nature, by tying that wither'd Bundle of Twigs to its sapless Tr unk;'tis now at best but the Reverse of what was, a Tree turn'd upside down, th e Branches on the Earth, and the Root in the Air;'tis now handled by every Dirt y Wench, condemn'd to do her Drudgery, and by a Capricious kind of Fate, destin' d to make other Things Clean, and be Nasty it self: At Length, worn to the Stumps in the Service of the Maids,'tis either thrown out of Doors, or condemn'd to its last use of kindling Fires.

请看看这根扫帚把，它现在灰溜溜地躺在偏僻的角落，而以前我曾在树林里碰见过它，那时它风华正茂，汁液充沛，枝叶繁盛。如今它完全变了样，却还有人自作聪明，想靠人类的手工同大自然竞争，拿来一束枯枝捆在它那早已干瘪的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢朝天，成为一株头朝下的树，然后落在干脏活累活的女仆们的手里使用。从此它受命运的摆布，把别人打扫干净，而自己却变得又脏又臭，在女仆们手里折腾多次之后，最后被扔出门外，或者作为引火的柴禾被投进火里。

It Newton iteration is used in the analysis of math value,and the simplicity formula is given to resolve(including original initial value formula and advanced approximation formula),which can be characterized by fast speed and easy remembering.

采用数值分析中的牛顿迭代法求反渐开线函数的根，并给出了符合精度要求的解算反渐开线函数的简单公式(包括原始初值公式和近似值精化公式)，具有迭代收敛速度快、简单易记的优点，它们适用于[0，π/2]的全区段，免除了分段计算的烦恼，并运用VB编写计算机程序，从而实现反渐开线函数快速求根的目的。

Tree seedlings with ectomycorrhizae or excised ectomycorrhizae have also been used as an inoculum source for new seedling crops.

具有外生菌根的苗木，或剪下的外生菌根，也曾被用作新苗木的接种源。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
