the lcd display character is acquisited by ccd,after analysis with image process and artificial neural network theory,through grid and intersecting lines to pick up the character′s characteristic,recognize lcd display character,provide with a kind of interface for the instruments and equipments which have no standard interface with the computer but have a lcd display.the experiment result shows that the system acquire and recognize lcd display character is very successfully,and high anti-jamming ability.

摘 要：利用ccd对lcd数码显示字符进行采集，在分析图像处理和神经网络理论的基础上，采用网格法与交线特征提取法，对lcd数显字符进行识别，为具有lcd数显而与计算机无标准通信接口的仪器仪表设备提供一种实用的无线接口。实验表明，系统对lcd数显字符采集方便，识别率高，并且抗干扰能力强。中图分类号：tm932；tp216 文献标识码：b

Choose a gear that allows you to hold the ideal body position on the climb too easy a gear will give you a fast cadence forcing you into the saddle and preventing from using your legs to absorb shocks on the other hand too hard a gear lead to a loss of momentum if you hit an obstacle a common error is riders who shift the little chambering too soon when approaching a hill climb this can cost a loss of momentum at the base of the climb when they need it the most.

选择适合的齿数来让你保持理想的爬坡姿势，用太轻的齿数，会导致踩踏转数过快，这会迫使你紧贴座垫，同时也会使你的双腿失去避震的作用。另一方面，在碰到障碍物时，若使用过重的齿轮组合，则会让你失去动力。

The polymers substituted with hexyl and octyl on phenylene also show a nematic phase, however, the nematic phase disappears for the polymer substituted with decyl. The polymers substituted with alkoxy on phenylene self-organize into a lamellar structure, and their phase behavior shows obvious dependence on the alkoxy length.

苯环上烷基、烷氧基取代的聚合物都具有纤维状的特征形貌，当烷基、烷氧基碳原子数为6时在高温都存在一个向列液晶相，当烷基碳原子数增加到10时液晶相消失，而烷氧基碳原子数增加到12时该向列液晶相仍然存在。

Lesion numbers on the inducer-treated plants treat with BTH, JZG and TS were significantly less than on control plants, in the meantime, treatment with BTH, JZG and TS led to an increase in activities of chitinase and β-1,3-glucanase in tobacco leaf tissue. Indicated these inducers triggered SAR in tobacco plants; in the same, BTH, JZG and TS were sprayed on the 1st leaf on melon plant before challenge inoculation with Erysiphe cidhoracerum.

发酵液、3—氨基丁酸(3-amin-butyric acid，3—ABA)和茉莉酸(Jasmonic acid，JA)等9种供试诱导剂在珊西烟上进行筛选：用各种诱导剂分别处理珊西烟从下数第6片真叶，上部第7、8、9叶挑战接种TMV，调查比较发病后枯斑数，筛选结果表明，只有经BTH、JZG和TS三种诱导剂处理的珊西烟叶片上的TMV枯斑数较对照显著减少，并能诱导珊西烟叶片中几丁质酶和β-1，3-葡聚糖酶活性增强。

Participants earned $10 to spend one hour in a soundproof booth while wearing headphones that played a different oice into each ear: one repeating fie digit sequences, the other garbling non sequitors and gibberish.

参与者为了挣10元钱要在一个隔音棚里戴着两只耳朵播放不同声音的耳机：一只耳朵是反复的从一数到五的数数，另一只是断章取义的言语凌乱的东西。

In many cases,even it is very difficult to find out good bounds of the crossing numbers of graphy .

Johnson已经证明确定图的交叉数是一个NP完全问题(见文献[4])，因为其难度，我们能够确定交叉数的图类非常少，在许多情况下，即使找出图的交叉数的一个好的上界或下界也是非常困难。

Within days, the hundreds had grown to thousands, and then tens of thousands, with total strangers forming teams to hunt down the student's identity and address, hounding him out of his university and causing his family to barricade themselves inside their home.

几天之内，数百人增长到了数千人，然后数万人，大量陌生人形成了穷追这个学生身份和地址的团队，把他逐出了他的大学，并导致他的家人躲在他们的家里。

It is to think network advertisement at or surpass traditional advertisement, cheap Mo place does not go to charge; 2 it is Shu of one-sided pursuit impression, impressional Shu is one of levels that measure network advertisement effect, but sometimes one Ge visits Ke Zai a website can produce ten Ge even Shu of two Ge impression; San is to feel integrated big website is straighter than hanging down effect of advertisement of site of is good, but accept the product ad with apparent feature of numerous target group to great majority, this kind of choice is unwise.

一是以为网络广告等于或胜过传统广告，费用低廉无所不到；二是片面追求印象数，印象数是衡量网络广告效果的标准之一，但有时一个访客在一家网站就可以产生十几个甚至二十几个印象数；三是以为综合大网站比垂直站点广告效果好，但对于大多数受众目标群体特征明显的产品广告，这种选择是不明智的。

The analysis of these data shows that in the process of evolution the X chromosomes are as conservative as those in other mammals and the intraspecific and interspecific changes of autosomes follow such a rule:the increase of one chromosome in 2n number is always accompanied by the increase of two acrocentrics and the decrease of one metacentric or submetacentric,and vice versa.

对这些材料所进行的分析表明，鹿属动物在进化过程中，X染色体是很保守的，而常染色体的变化，无论是种间还是种内，全是2n数每增加1条，中部或亚中部着丝点染色体数就减少1条，而端着丝点染色体数就增加2条，反之亦然。

By means of molecular designing, a series of sodium branched-alkyl benzene sulfonates weresynthesized through seven process, involving Frieded-Crafts reaction, Grignard reaction, sulfonationand neutralization. Those isomers have similar structure, carbons of same quantity, but the position ofalkylaryl dissimilarity. Liner fat acid, metaxylene and halogenated hydrocarbon of different carbonnumber were used as the starting materials. Optimum processing condition was confirmed consideringinfluence of a series of reaction factors such as feed proportioning, quantity of catalysts, quantitysolvent, reaction time, temperature and pressure. Eight kinds of isomers of sodium hexadecylxylolsulfonates were finally synthesized, and characterized by FT-IR.

本文通过分子设计，以不同碳数直链脂肪酸、间二甲苯以及不同碳数的卤代烷为原料，经酰基化、格氏反应、加氢还原、磺化及中和等反应，合成了结构相似、烷烃链碳数一定、芳基在烷烃链不同位置的烷基芳基磺酸盐同分异构体；并考察了原料配比、催化剂用量、反应时间、反应温度、溶剂用量、反应压力等一系列因素对各反应的影响，进而确定最佳工艺条件，最终合成出十六烷基二甲苯磺酸钠的八种同分异构体，利用 FT-IR 对产物结构进行了分析。
