小链

Above: Rear engine compartment showing shock-mounted rear wheel, enclosed chain drive, and small stabilising wheels.

以上：后方引擎显示休克式后轮，封闭链传动，稳定和小轮子。

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.

配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。

The trick to getting a high score in the game, is to build longer and longer chains of bubbles by removing smaller chains in such a way as to move like-colored bubbles together.

的伎俩，想获得较高评分，是建立长链的泡沫，消除小连锁的方式将彩色一样的泡沫。

The occurrence and development of disaster show an orderly structure of disaster chain on transmission,which results in a lot of difficulties to prevent and control the disasters.

灾害的发生发展呈现链式有序的传承效应，为灾害的预防和控制带来了不小的困难。

VNTR strain typing was suitable to trace the short chain of transmission in both small area and intra-families.

结论无论从家庭内或较小区域内收集菌株的分型结果显示，VNTR基因分型适合麻风菌分型和短传播链的研究。

A NetCoin payment consists of two parts, a digitally signed payment authority and a separate payment token that determines the amount.

根据小额电子信息交易系统的每一次交易金额非常小这一事实，NetCoin交易协议采用了&轻量级&的密码学安全机制和离线的认证方法，利用Hash函数构造的随机数链来作为交易的付款方式，卖方可以不联系NetCoin网关而离线的认证一个匿名的买方，从而使系统具有很高的效率和较低的开销，并且能提供买方对卖方的匿名性。

The concrete steps are: the lactic acid and small-molecule dicarboxylic acid react under the condition with the presence of the catalyst to directly polymerize the carboxyl-terminated lactic acid prepolymer; then the aliphatic polycarbonate diol and the catalyst are added; with the presence of the N2, the reaction is kept for 1 to 10 hours at the temperature of 150 to 200 Celsius system to get the poly lactic acid and polycarbonate copolymer of the low molecular weight; then the reaction is done in the twin-screw extruder at the temperature of 150 to 190 Celsius system to screw out the extension chain; finally the polylactic copolymer of the high molecular weight, toughness and heat resistance is made.

具体步骤是：乳酸和小分子二元酸在催化剂条件下反应直接缩聚合成羧基封端的乳酸预聚物，然后加入脂肪族的聚碳酸酯二元醇和催化剂，在N 2 气氛下，抽真空，在150～200℃温度下，反应1～10小时，得到低分子量聚乳酸/聚碳酸酯共聚物，然后在双螺杆挤出机中在140～190℃下，进行反应挤出扩链，最终得到高分子量的、韧性与耐热性较好的聚乳酸共聚物。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
