The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.

摘 要：2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查，结果表明，投礁后礁区海域游泳生物的资源密度明显比投礁前高，增加了25.63倍；礁区海域各类资源种类均比投礁前丰富，总种数由投礁前的23种增加至41种，比投礁前增加了0.78倍，其中，蟹类种数增加最多，增加了1.75倍；在本底调查中没有出现的经济种类龙头鱼 Harpodon nehereus 和红星梭子蟹 Portunus sanguinolentus 在跟踪调查中已成为主要优势种；Shannon-Wienver多样性指数在礁区和对比区均比投礁前有所增加。

Predeterminer):all,both,half;double,twice, three times,etc;one-third,two-thirds,etc;what,such, etc 中位限定词:the,a,zero;this, that,these,those;my,your,etc:John's,the old man's,etc; some,any,no,every,each,either,neither,enough,what, which,whose,etc 后位限定词:one,two,etc;first,second,etc;next,last,other,etc; many,much, few,little,fewer,fewest,less,least,more,most;several,plenty o f,a lot of,lots of, a great number of,a greatdeal of,a largeamount of;such,etc

在三类限定词中，中位限定词是最关键的。所谓前位限定词是指那些可以位于中位限定词之前的限定词，所谓后位限定词是指那些可以位于中位限定词之后的限定词。例如： all the four teachers 所有这四位教师前中后上述限定词的位置是固定的，不能掉换，就是说它们必须按"前位—中位—后位"的顺序排列。以此类推，如果出现两个限定词，则只能按前位—中位，前位—后位或中位—后位的顺序排列。

The effect of treatment is negatively correlated with the course of disease, generally, the effect is much worse with the course of disease is much longer; The effect is positively correlated with the course of treatment, it is better if the course of treatment is longer.The group of more than one year is much excellent than the group of less one year. The ex-electroencephalogram before treatment is normal, on edge and a little abnormal, the effect is better. As regards CT or MR result, there is difference between the effective group and the ineffective group. The result of CT and MR is negative, the effect is better, and the effect to demyelination and leukoencephalopathy is most worst.However,for the tipe of much abnormality, the effect is the most worst.The effect is related to course of disease.The effect is better if the course is shorter.There is no difference in the tipe of disease the symptoms before episode, the frequency of episode, the inducing reasons, the age, sex and so on.

病程的长短与疗效存在负相关关系，病程越长疗效越差；疗程与疗效存在正相关关系，疗程越长疗效越好；疗前脑电图的异常程度与疗效存在负相关关系，正常、边缘及轻度异常者，疗效较好，重度异常者疗效最差；无效组与有效组在CT及MR检查结果上有差异，有阴性者疗效好，阳性者疗效差，脱髓鞘及脑白质病疗效最差的趋势；疗效与性别无相关性；无效组与有效组在发作类型、既往病史、辨证分型、发作先兆、疗前发作频率、诱因、发病年龄、就诊前所用药物方面无差异。

This article considers that the pre-schooler special-purpose school bus market potential is huge, after the analysis of the present situation of pre-schooler education in our country and pre-schooler school bus accidents in partial provinces and cities during 2005～2007. The security situation of school buses is unoptimistic. From the perspective of security, the complete form of the pre-schooler special-purpose school bus is reqestted on the basic of study of the school buses security measure in home and abroad. According to the statistical analysis of the human body size related to 3～6 year-old pre-schooler, the child chair's 6 main parameters, the passenger gate steps, and arm rest's size, as well as crossing control arm's mounting height and performance requirement have been determined. According to the present domestic and outside related standards to exports to the bus and school bus, the least quantities and most light-sized of the exports of school bus are proposed. According to the present domestic and outside standards to the request of driver's field of vision of bus and school bus, the essential requirements and inspection procedure of the field of vision of the pre-schooler special-purpose school bus are setted.

本文通过对我国学龄前儿童教育的现状和2005～2007年部分省市的学龄前儿童校车事故分析，认为学龄前儿童专用校车的市场潜力巨大，校车的安全形势不容乐观；在研究国内、外校车的安全措施基础上，从安全角度出发，对学龄前儿童专用校车提出了整车要求；根据对3～6岁学龄前儿童相关人体尺寸的统计分析，确定了学龄前儿童专用校车儿童座椅的6个主要参数、乘客门踏步和扶手的尺寸，以及横向控制臂的安装高度和性能要求；根据国内、外现行标准中对客车和校车出口的相关规定，提出了校车出口的最少数量和最小尺寸；按照国内、外现行标准中对客车和校车驾驶员的视野要求，提出了学龄前儿童专用校车驾驶员视野的基本要求和检验方法。

The protease activity in foregut was higher than that of midgut in an acidic condition at pH 5.0-5.8, while in an alkalescence condition at pH 7.0-8.6, the protease activity was higher in midgut than that in foregut. The lipase activity of foregut was high and stable in two pH ranges: 4.2-5.0 and 6.2-7.0, and that of midgut was high at pH 3.8, while the lipase lost enzyme activity at pH over 9.0. The amylase activity was high and stable at pH 6.6-7.4 in both foregut and midgut. The cellulase activity of foregut and midgut was high and stable at pH 6.2-7.4 and 5.4-7.0 respectively.

刺参前肠蛋白酶活力在酸性环境下较中肠高，且在反应pH为5.0-5.8之间酶活力相对稳定，而中肠蛋白酶活力在碱性环境下较前肠高，且在反应pH为7.0-8.6之间酶活力相对稳定；刺参前肠脂肪酶活力随着pH的升高出现两个相对稳定的峰值，分别为4.2-5.0和6.2-7.0区间，中肠脂肪酶活力在pH为3.8时达到最大值，而在pH超过9.0明显失活；刺参前肠和中肠淀粉酶活力在pH变化时表现出相似的变化趋势，在反应pH为6.6-7.4之间酶活力较高且相对稳定；刺参前肠和中肠中纤维素酶活力在pH变化时反应不一致，前肠淀粉酶在反应pH为6.2-7.4之间酶活力较高且相对稳定，中肠纤维素酶活力在反应pH为5.4-7.0之间酶活力较高且相对稳定。

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是靠模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的靠模，加工时把工件毛坯和靠模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动，从而切割出与靠模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作靠模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴，是由前苏联人发明的，我国是第一个用于工业生产的国家，当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型，我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS
