The research contents and main conclusions are as follows:1. The present thesis adopted one-dimension interior ballistic model, regarding the ballistic spatial core as the unsteady quasi one-dimension airflow containing the friction and heat exchange between airflow and tube wall, considering the boundary layer unsteady, nonstationary condensable current; and employed the MacCormack finite difference method to write the program.

本文的研究内容及结论主要体现在以下几个方面： 1、采用了一维内弹道模型，把弹后空间的核心流部分考虑为包含气流与身管管壁发生摩擦和热交换的不稳定准一维流，边界层考虑为不稳定、非定常可压缩流，用MacCormack有限差分方法求解，编制程序进行计算，较为准确的得到了复合材料身管固壁瞬态温度场分析内边界条件所需的气流温度和对流换热系数结果。

Omental GISTs unattached to gastrointestinal tract often resemble gastric GISTs suggesting that they may be gastric GISTs directly extending or parasitically attached into the omentum, whereas multiple omental GISTs more often resemble small intestinal GISTs suggesting that they may be metastatic or detached from this source.

不与胃肠道粘连的网膜GISTs常类似胃GIST，它们有可能是胃GISTs的直接延伸，或是寄生于网膜中（只不过最初与胃连接的地方已不存在）。

He that seeks victory over his nature, let him not set himself too great, nor too small tasks: for the first will make him dejected by often failings; and the second will make him a small proceeder, though by often prevailings.

He that seeks victory over his nature, let him not set himself too great, nor too small tasks: for the first will make him dejected by often failings; and the second will make him a small proceeder, though by often prevailings.

一个人想战胜自己的本性（或意译&改变自己的坏习惯&），他就不要给自己订的任务既不能太高，也不能太低；太高会使他因常常失败而灰心，太低又会使他虽常有效果但进步太小。

Third, on the base of Construction Grammar, this thesis not only uses metalanguage to interpret the vague event, but also retrieves the semantic components from the whole construction. In other words, this thesis postulates: although these three verbs are not full fledged pro-verbs in some cases, they behave like pro-verbs that they are 'super-lexical' morphemes and act differently from other predicates which just render a situation type for the event. For example, the frame-evoking verbs may change the situation type of an activity into a resultative state, or imply that the speaker takes business as an informal event in a rather pejorative tone.

再者，本文除了发现格式语法可以透过后设语言明确描述隐含的事件，并且可以透过对整个格式语意成分的提取，尽管在某些情况下尚不成熟，但可将这三个常项动词设定成整个语意框架内的「代动词」，换句话说，这三个动词的地位是在一般词汇之上，因为他们不像一般动词那样只给所带出的事件一个「动相类型」，而是可以提供整个语意框架较多的语意诠释：可能是一个事件状态的改变，例如：产生一个「结果状态」，或是使整个框架得到一个作说者对待事件的「角度」，例如：作说者用比较「贬义的角度」来看待该隐含的事件等等。
