不同年龄北豆根一级根状茎在根长、根径上差异显著，在数量上差异不显著。

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。

In the second part, it is argued that the effect of Novum Organum on the philosophy and science is just as the function of beacon. The thesis in this part systematically introduces Bacon\'s basic and extensive thoughts excluding Baconian Induction, Theory of the Idols and the Empirical Epistemology that people have thoroughly researched; moreover, the mistakes which people have made are corrected and the limitations of the viewpoints of Novum Organum are also focused on. In the third part, Bacon\'s basic and extensive scientific and technological researches are discussed. Regarded to this, the thesis finds that people only paid attention to Bacon\'s view that heat is a motion which Bacon took lots of space in Novum Organum to summarized according to Baconian Induction.

本文总共分为四大部分：首先，分析《新工具》是对亚里斯多德《工具论》的勇敢挑战，并着重论述了培根的政治和文化背景对他的新思想所造成的深刻影响；其次，系统探讨《新工具》在哲学和科学中起到的灯塔作用，本文论述了培根的基本哲学和科学思想及具体应用和反映，但是对前人已深入探讨过的培根式归纳法、四假象说和经验认识论不再论述，同时对前人的一些误读进行澄清，并分析培根的《新工具》在哲学和科学思想方面的局限；再次，对前人很少涉猎的《新工具》中的科学研究方面进行系统论述，本文发现人们基本上仅仅注意到了培根在《新工具》中大篇幅运用培根式归纳法进行举例论证的热动说，而对这本书中其他的科学研究不甚关注。

The ultra structural changes of nerve root arc the pathological basis of the function loss of the nerve root. The present model is more closer to the model of lumbar intervertebral disc herniation and stenosis of nerve root compression and it provides a basis for treatment of compression caused radicular pain and numbness in clinic.

神经根超微结构的改变是神经根失功能的病理形态学基础，此模型更接近于腰椎间盘突出和椎间管狭窄对神经根的压迫，为临床神经根性疼痛及麻木治疗的研究建立了可供参考的动物模型。

The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.

在已有分析法得到t时刻平均根数的基础上给出一种轨道预报方法，由t时刻的平均根数给出该时刻卫星的位置和速度，在此基础上将地球非球形引力摄动的周期项直接用卫星直角坐标的位置和速度分量表示，这样可以避免在计算轨道根数变化的周期项时出现的奇点问题，从而对根数的选择无特殊要求，可适用于各种轨道，简化预报程序和相应的软件，提高预报效率。
