Also a simulation program is developed to calculate the working properties of the impactor. By using the simulation program, the variation laws of the basic parameters of the hydraulic impactor under different structural parameters and hydraulics are obtained.

Fragments from the 239th to the 944th nucleotide of the coding regions of all actin mRNAs were amplified with two actin specific primers. Fragments from the 239th nucleotide of the coding region to the end of actin mRNAs were also amplified The electrophoresis results were compared between the macropterous and brachypterous brown planthoppers.

利用两条肌动蛋白特异性引物，扩增出了肌动蛋白基因mRNA的编码区片段，另外，将肌动蛋白特异性引物作为上游引物，将与3'锚定反转录引物部分序列相同的引物作为下游引物，扩增出了从肌动蛋白基因mRNA的编码区第239号碱基到Poly尾的这段cDNA，并在翅型之间作了比较。

The category is designed to include a group of children with severe mental retardation (IQ below 50) who show major problems in hyperactivity and in attention, as well as stereotyped behaviours. They tend not to benefit from stimulant drugs (unlike those with an IQ in the normal range) and may exhibit a severe dysphoric reaction (sometimes with psychomotor retardation) when given stimulants. In adolescence, the overactivity tends to be replaced by underactivity (a pattern that is not usual in hyperkinetic children with normal intelligence). This syndrome is also often associated with a variety of developmental delays, either specific or global.

因有下述特徵则作此诊断：出现注意力不集中及过动行为的重度智能不足（智商低於 50 ）；给予兴奋性药物治疗并不能改善此类儿童的情况，反而可能会有情绪低落反应在少年期少动行为常取代过动行为（这种情况在正常智商的过动儿童并不常见），同时常并发特定或全面的发展迟滞。

Genome, and its expression products are located in the flagellar, cytoplasm and fertilization tubule. Cr. actin is partially purified from Cr. cells by the method of assembly-disassembly-circle of actin.

本文基于 PIV 处理颗粒流动图像获得了颗粒流动的瞬时速度；基于功率谱密度分布对瞬时速度的分析结果表明，喷射区轴线的中下部颗粒存在较强的速度脉动，环隙区颗粒速度脉动较弱；研究发现喷动周期与床体压力脉动周期基本一致。

On the basis of summarizing and commenting upon the major studies of semantic orientation of resultative construction in modern Chinese, the paper claims it is insufficient to study semantic orientation of resultative construction only from the literal or formal logic point of view, but rather, researchers should take into account some subjective factors on the part of language users; then, the paper introduces Talmy's cognitive semantic approach to resultative construction; based on his theoretical framework, the present paper further investigates the internal causes of the diversity of semantic orientation of satellites in Chinese,supported with the data analysis; and finally, this paper concludes that it is the semantic and syntactic properties of the verb root that make these diversified semantic orientation possible, and their actual representation is finalized by the language user via different satellites.

本文在对以往动补结构语义指向的主要研究成果进行总结评价的基础上，提出对语义指向的研究不能停留在字面和形式逻辑的层面上，而应结合语言使用者的主观因素或主观经验，也即是认知语义学的观点；其次，系统地介绍了Talmy的认知语义学观点中关于汉语动补结构的重新描述和分析，并在此基础上，着重分析了汉语动补结构多样化的语义指向的内在原因，即，汉语动作动词特殊的词汇化模式(仅包括动作和使动成分在内)中不包含确定动作执行结果的成分，因而须要借助于其卫星成分来表明动作的结果，这个结果可能是规约性的结果，也可能是偶然性的结果，由此呈现出卫星成分的多义性的特点，也就是传统上说的动补结构的语义指向。
