In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.

在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。

In chapter 4, we define the projective dimension of flat modules, use it to characterize many rings, and the relations between cotorsion modules and the projective dimension of flat modules are also given.

在第四章中，我们定义了平坦模的投射维数，用它刻划了一些环，并讨论了Cotorsion模和严坦模的投射维数的关系。

The teaching term took sixteen periods. The curriculum contained two topics,"acid and base", and "Taiwan's climate". Experimental treatments were teaching method. The research tools utilized in the study were " Science Concept Comprehension Test, Science-related Attitudes Scale, Problem Solving Ability Test and Questionnaire on the Attitude toward Science Teaching". A pretest administered before the experimental treatment and a posttest was held after the treatment. The data of SCCT, SRAS, and PSAT collected from pretest and posttest were analyzed by two-way ANOVA. Responses from the QAST were analyzed by ANOVA.

本研究的实验处理为以问题为中心的合作学习教学，研究工具包括「科学概念理解问卷」、「科学相关态度量表」、「问题解决测验」、「对自然科的教学态度问卷」、「教学检核量表」及「问题中心教学自我评估量表」，分析「科学概念理解问卷」、「科学相关态度量表」和「问题解决测验」资料时，以前测经验和教学法为自变项，后测为依变项，进行二因子变异数分析；「对自然科的教学态度问卷」采用单因子变异数分析；「教学检核量表」及「问题中心教学自我评估量表」则用来检核研究者的教学是否符合研究者的研究设计；在质性资料的部分，则分析学生的上课纪录、教师教学反省纪录及对自然科教学的态度问卷的理由。

I mean, said Miss Marple, puckering her brow a little as she counted the stitches in her knitting, that so many people seem to me not to be either bad or good, but simply, you know, very silly.

"我指的是，"马普尔小姐说，微蹙着眉头数着编织的针数，"在我看来，很多人不能说是坏的或者好的，但是简单地说，你知道，非常愚蠢。"

If purificatory measure does not be taken, the content of HCl gas in the air will arrive at several tens or hundreds mg/m~3 more.

在化工、造纸、电镀、油脂等行业中不可避免地要产生氯化氢废气，如不采取净化措施，会使车间空气中氯化氢废气的浓度达到数十甚至数百mg/m~3 ，远高于环境卫生标准0.3 mg/m~3。

in a routing as, multiple igp and egp protocols are used to exchange routing information.this paper extends the function of rip based on the deep analyze of rip protocol and modification of quagga code.normal rip measures the distance through the number of hops as the metric.this paper introduces some new command factors combining the hop and adds new entries into the routing table for in order to extend the functionality of quagga and protect the network.

通过对rip协议的深入研究和对quagga代码的分析、修改，文章对rip协议的运用进行了扩展。普通的rip协议以到达接口的跳数作为衡量距离的标准，文章在此基础上引入新的命令因子（阻塞命令、非阻塞命令、系统负载等），这些命令与跳数的转换相结合，向路由表内加入特殊路径，从而实现quagga功能的扩展和网络的保护。

In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups. It is concluded that PMPs show promotive effect on the formation of capillaries in chick chorioallantoic membranes.Key words platelet??

而在对照组无特异性密集血管生成，血管分支数为82.6±8.05，血管面积为1.78±0.33，二组比较有显著性差异（P＜0.05）；而与VEGF组比较，后者的血管分支数为128.4±10.02，血管面积为7.44±1.36，二组比较差异无显著性。
