Students have grasped this kind of model in the primary stage, while apply it in practice they still repeat the theme of the former sentence, which means that Vietnamese students are not skillful at the discourse cohesion; in the middle stage, there are passive sentences and "catenulate"sentences, but some of the students bring on grammatical errors while assuring the cohesiveness of discourse; in the advanced stage, the second cohesive model disappears while amount of third cohesive way appears which even more than the second one, which shows that students no longer stand on the cohesiveness formally but to make the "zero"cohesive of discourse.

另外我们还在语料中发现了被动句的语体风格出现偏差的情况。在运用被动句的语篇衔接功能时，留学生普遍运用第一种主位推进模式。在初级阶段学生就已经基本掌握了这种模式，但有时会不必要地重复前句的主位，这说明留学生对汉语的语篇衔接还不够娴熟；有的学生不能够使用被动句完成语篇衔接，可能是受词汇量的影响。

Polyaspartate can also be obtained through chemical synthesis, but is currently produced only in small quantities. It is more biodegradable than comparable polyacrylates, but not totally biodegradable like the polyaspartate produced in cyanophycin.

聚天冬氨酸也可以通过化学方法合成，但是，目前只能少量生产，其生物降解性比聚丙烯酸酯更好，但不能够像蓝细菌中产生的聚天冬氨酸那样完全被生物降解。

从表2中可以看出，低温、氮气条件下，PU-1分解主要可辨别的组分为1，4丁二醇，（Fig.5a）中m/z71不能够辨别，（Fig.5b）显示了m/z71离子谱图，这些峰一定是聚合物多元醇热降解产生的低聚物。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

He explained that Franklinist electrical matter cannot itself be the cause of electrical motions because it flows unidirectionally, from highest potential to lowest potential, while in the most common experiments, the same electrified body simultaneously imposes both attractions and repulsions.

他解释富兰克林的事件是因为电不能够它本身单向流动，是因为电运动的因素，从最高的位能对最低的位能，在最普通的实验方面的时候，被通电的身体一样的同时地强制吸引和击退。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
