In these years a lot ofresearches on these materials have shifted to their behavior under energic particleirradiation, because they have been regarded as promising candidate materials formany important nuclear applications.

近年来大量对这两类材料的研究却逐渐开始关注其在高能粒子强辐照条件下的行为，因为金属氧化物现在被认为是极有潜力的核技术结构材料，而SiC除了作为重要的核工业结构材料之外，作为半导体材料也一直被作为能在极端条件下正常工作的新型半导体材料。

When we communicate with each other using something from Chinese , the writer thinks that we are using surfacely the characteristics of its tools, in fact we are perfecting its humanity in connotation here. It contains mind ,attitude, value sense, moral accomplishment and other poly consciousness. Well, how to transmit these truly, honestly, abundantly, and enlightenedly to make it come into the soul of humans, all of these are the things that are worth thinking by our teachers whose duty is to transmit the cultures and reasons, teach knowledge and solve the puzzles of the students.

当我们用语文中的某些东西进行交流和沟通的时候，笔者认为表面运用的是语文的工具性，实际在内涵上我们正在完善它的人文性，这里面包括思想情态、价值观念、品德修养等多元化的精神意识领域的东西，那么如何能够真实的、诚挚的、丰富的、启发的传递这些，使之更广阔的深入到人类的心灵之中，这应该是值得我们&传道、受业、解惑&的教师所要深刻思考的事情。

This paper focuses on how to calculate GPS satellite orbit parameters through IGS data. Choosing a group of appropriate parameters, and the relationship between satellite position in ITRF and these parameters are founded, and these parameters can be estimated using some successive ephemerides. Three different methods are introduced detailedly.

本文以IGS精密星历为基础，深入研究了利用精密星历计算GPS卫星轨道参数的模型与方法，并对三种不同的计算方案进行了比较研究，其目的是寻找一种合适的计算方法，得到能够正确反映一个较长时间段内(如800天)轨道参数随时间变化的规律。

The big difference between these two alternatie ways that tumour cells use to inactiate tumour suppressor genes is that, while the reersal of genetic alterations is technically almost unfeasible in clinical scenarios, the function of these epigenetically inactiated suppressor genes is easily reactiated by pharmacological means.

这两种改变方式最大的不同之处在于肿瘤细胞利用失活的肿瘤抑制基因，而在同时相反的遗传学改变在临床方案上是很难实施的技术。

Researchers also examined the use of resuscitation and delivery-room characteristics. As expected, the use of occlusive wrap and sodium-acetate-gel mattresses led to lower percentages of neonates with hypothermia. Of hypothermic neonates, 85% who were 28 weeks OB EGA or younger underwent positive-pressure ventilation or intubation, whereas only 76% of euthermic neonates underwent these procedures (P?=.04), suggesting an increased risk for hypothermia with these procedures.

研究者也检视使用复苏与产房的特征；一如预期，使用闭合包巾和醋酸钠凝胶床垫可以降低新生儿低温比率；低温新生儿中，85%的OB EGA不到28周，有接受正压呼吸或者插管，而只有76%的适温新生儿接受这些照护(P=。04)，表示这些照护会增加低温风险；St。

Situation of the utilization of experiment resources:(1) The opening up of the laboratory are relatively weak aspect, so, in these schools, students have few chances to do extra-curricular experiments;(2)Almost all of schools teaching experiment instruments are used, less instrument is not used, the main reason for not used is that these experiment instruments are irrelevant with materials or they are obsolete and damaged;(3) Teachers always experimentalize according to the teaching materials step-by-step, there is no improvement;(4) Most teachers don\'t pay attention to the evaluation of experiment result, students merely write expriment report;(5) The teachers have realized some significance of inquiry experiments, but have not begun action consciously.

从实验教学过程和实验资源开发利用情况看：(1)实验室的开放是比较薄弱的环节，绝大多数学校只有上实验课时才开放实验室，因此这些学校的学生进行课外实验和小制作的机会很少；(2)绝大多数学校实验教学仪器的利用情况较好，闲置仪器较少，其闲置的原因主要是实验内容与教材无关或仪器陈旧损坏；(3)实验过程基本上是按教材提供的步骤进行，教师对实验过程和教学仪器的研究和改进较少；(4)很多教师不重视对实验结果的评价，学生很少写实验报告；(5)教师对探究性实验的意义已有认识，但还没形成自觉行动。
