Large numbers of experiments internal and external had confirmed both direct current and square pulse of distal end cathodal could improve peripheral nerve regeneration, because it could speed up transmigration, creeper, growth and development of cell Schwann, derivate growth of nerve fiber; it also increased blood capillary of epineurium, brood blood vessel, amendment ischemic of impaired nerve, it still could accelerate Wallerian

国内外大量的基础实验及临床研究都证实远端负极电流的直流电场及脉冲电场等均有促进周围神经再生的作用，认为其可加速Schwann细胞的游走、爬行及生长发育，诱导神经纤维的生长；电刺激还能促使神经外膜毛细血管数量增多，扩张血管，改善神经损伤段缺血状态，并加速Wallerian变性及崩解组织的清除，为Schwann细胞发育和髓鞘化过程提供充足的能量与物质，同时为神经轴突的再生提供良好的内环境；在神经断端出现瘢痕或神经瘤时，电刺激可增加神经纤维穿越瘢痕的能力。

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

In the system of high precision and low speed, Because of the existence of the nonlinear friction, the static and dynamic performance of the servo system is very bad, such as stick slip, hunting, large error and so on, Because the traditional control of PID is hard to solve the nonlinear problem of the servo system, so this paper begins to introduce a new control method which is named adaptive fuzzy PID, It utilizes the rule of the fuzzy control to adjust the parameter of proportion, integral and differential on line, So this control method has some intelligence to improve the static and dynamic performance of the servo system.

在高精度、超低速伺服系统中，由于非线性摩擦环节的存在，使系统的动态及静态性能受到很大程度的影响，主要表现为低速时出现爬行现象，稳态时有较大的静差或出现极限环振荡；由于传统的PID 控制很难解决伺服系统中的非线性问题，因而不能适用于高精度、超低速伺服系统；本文通过引入模糊自适应整定PID控制，利用模糊规则在线调整比例、积分、微分环节，使系统具有一定的智能，从而非常明显的改善伺服系统的静态及动态性能。

Every level presents new and exciting opportunities to defeat enemies with Sid's spin attack, utilize Buck's lasso to swing across treacherous landscapes, avoid obstacles as Scrat using his wall jumping and ceiling crawling abilities and escape from perilous situations flying on the back of a pterodactyl with Buck, Crash and Eddie.

Based on the analysis of a group of gait plates of quadrupedal animals, the conformity and continuity among all gaits from crawl through gallop are revealed. A unified mathematical model of various gaits is established, which forms the basis of further study of analysis and control of gaits.

通过对四足动物步行运动步态的图片资料的分析，揭示了动物从爬行到奔跑之间各步态在时序上的一致性和在步态参数上的连续性的内在规律，建立了这些步态统一的数学模型，该模型可作为动态步行运动分析和控制的基础。

So I read every day sitting under a tree by my tent, while warblers sang in the leaves overhead and beside worms trailed their inches over the twiggy dirt at my feet, and I read every night by candlelight, while barred owls called in the forest and pale moths seeking mates massed round my head in the clearing, where my light made a ring.

所以我每天坐在帐篷边的树阴下读，小鸟在头顶上的叶子里唱歌，旁边的小虫在脚旁的松土上爬行。每晚当猫头鹰在树林里鸣叫的时候我挑灯夜读，苍白色的飞蛾就会聚集在我头顶上的由烛光形成的光圈处寻找配偶。

How many a poor immortal soul h****e I met well-nigh crushed and ****othered under its load, creeping down the road of life, pushing before it a barn seventy-five feet by forty, its Augean stables (7) never cleansed, and one hundred acres of land, tillage, mowing, pasture, and woodlot!

The results of The biological characteristics of Semanotus bifasciatus have showed: 1. The hole of Semanotus bifasciatus associated with a certain temperature.2.The main damages of Semanotus bifasciatus located oriental arborvitae tree trunks, while above 3m parts are not damaged. 3.The Mating numbers of Semanotus bifasciatus are not unique ,and the duration varied due to the different individuals, the average duration is 3.2 minutes . 4. when are flying , they are more sensitive to blue and green; while moved, they are more sensitive to black.
