As one of Form-Position Errors, Positional Error does not only control single item but also Form Errors such as perpendicularity, parallelism, angularity, straightness. This paper studies the theory and technique of Error Separation.

在形位误差中位置度误差在控制单个要素或成组要素位置精度的同时，还综合控制了垂直度、平行度、倾斜度、直线度等误差项目，因此本论文重点研究讨论误差分离理论和分离技术在位置度误差评定中的应用。

To obtain the function and imbedding properties about relative countable tightness spaces,in this paper the question whether the relative countable tightness space can be adversely preserved by a closed map is studied by means of function and imbedding theories.

为了得到相对可数紧度空间的映射及嵌入性质，借助映射方法和紧化理论讨论了相对可数紧度空间被闭映射逆保持问题及嵌入紧空间问题，得到了相对可数紧度空间被闭映射逆保持的一个充分条件、局部紧的可数紧度空间可嵌入紧空间的几个充分条件以及某一类局部紧空间在任意紧化中不具有可数紧度等结果。

In addition, when the modified PVA resins fulfilled requirements in the following: 1 the acetalization degree varied from 60 mol% to 80 mol%, 2 the esterification degree varied from 10 mol% to 20 mol%, 3 the amount of hydroxyl group was 5-25 mol%, 4 the range of value of B/P(the mass ratio of the binder to diazo resin) was from 4 to 4.5,5 the range of its molecular weight was from 4×10^5 to 8×10^5, the negative PS plate obtained had excellent sensitivity, hydrophobic property, good developability, good ink receptivity and good scratch resistance.

因此其分子量、酯化度和缩醛度的确定，必须综合考虑各项性能之间的平衡。缩醛度为60-80 mol%，酯化度10-15mol%，羟基5-25 mol%，分子量约为4-8万，B/P为4-4.5时，制得的阴图PS版的感度、显影性、着墨性和耐磨性都较好。

Respecting this, zhang Guanxi's engineer takes goblet quaff, rely on on the chair to continue respecting: Baidu has 3 big competitors at present: It is Gu Ge, it is Tecent, it is the portal station; such as sina, Netease among them cereal song nip is giant capital and top technology actual strength, whole break down Yahoo after this is only dinosaurian, it is at the summit of one's power more, together with is familiar with Chinese to search a field gradually, hold concurrently with Adsense draw over the heart of the world stationmaster, discharge day is tall, except Baidu has powerful support in respect of governmental public relations, lose; of city lost territory already and Tecent, have the user group of nearly 200 million, the horse changes Teng Qian to reside Shenzhen, be covetous on searchs engine this cake is long already; another competitors namely each big door station, root deep tree is tall, more development searchs the criminal record of engine, all along also is to peep the; together with that search index props up this cup of a thick soup Baidu appears on the market now, capital drive technology, baidu now is must nod wildly, for discharge insanity, for silver insanity, you these careless root stationmaster are the act that understands Baidu very hard.

说到这，张冠西工程师拿起酒杯一饮而尽，靠在椅子上继续说到：百度目前有三大竞争对手：一是谷歌，一是腾讯，一是新浪、网易等门户站；其中谷歌挟庞大资金及顶尖技术实力，整垮掉雅虎这只恐龙后，更是如日中天，加之渐渐熟悉中文搜索领域，兼用adsense笼络了天下站长之心，流量日高，若不是百度在政府公关方面有强大支持，早已丢城失地；而腾讯，有近2亿的用户群体，马化腾潜居深圳，觊觎搜索引擎这块蛋糕已久；另外的竞争对手即各大门户站，根深树高，并多有开发搜索引擎之前科，向来也是偷窥搜索引擎这杯羹的；加之现在百度上市，资本驱动技术，百度现在是不得不疯狂点，为流量疯狂，为银子疯狂，你们这些草根站长是很难了解百度的举动的。

It is that:(1) the related compounds in Metronidazole Buccal Tablets prepared by Chongqing Medical College can be tested by determining (321nm) the total peak area of the impurities;(2) The related compounds in Metronidazole Disodium Phosphate for Injection prepared by Chongqing Medical College can be test by determining (254nm) the total peak area of the impurities and the peak area of the largest impurity;(3) Ceftriaxone polymer in Ceftriaxone Sodium for Injection prepared by Chongqing Keru Pharmacy Co.

In order to research the sugar accumulating regulation of sweet sorghum, the relationship between the brix of every internode and average brix of its whole stem was studied. This paper used varieties MNS-1, MNS-2 and stem brix of sweet sorghum in different period. The result showed that the variation of early matured and late matured varieties of sweet sorghum had same tendency in brix in same growing period, but had different values.
