During the process of making Doberman pinscher, we dyed the cow skin into black or brown, cut the hair down piece by piece and transplanted them onto the silicone model. We calculated carefully and strictly on the color distribution, growth trend and the length thickness. We promoted the dog's hair to grow by the speed of five square centimeters per day. And at the same time, after several tedious mechanical debugging, we gradually made it breathing. And finally it became a lively Doberman pinscher.

在制作杜宾犬的过程中，我们把牛皮上的毛调染成黑色和褐色，一小撮一小撮的剪下来，植在硅胶胎上，精打细算毛的色彩分布、生长走向、粗细长短，以每天五平方厘米的推进速度让狗的毛慢慢生长出来，同时经过反复而乏味的机械调试，逐步使它产生呼吸，成为一只有生命的杜宾犬。

利用高解析的光学显微技术，我们得以准确地观测接连在DNA及玻片表面的乳胶小球之布朗运动情形，并藉由其布朗运动的大小直接对应到在生化反应中DNA长度的变化，因此单分子拴球实验已被广泛地应用於研究单一蛋白质与单一DNA分子作用之反应机制。

The chemical composition research aspect literature report are extremely few: According to reports, the root of Rosa davurica pall includes the lactone, the tanning substance, the return to original state sugar, the total lucoside, the flavanone, the phenol class, the biological alkalis, the protein, the anthraquinone equi com ponent, moreover ,the total polysaccharide is the even polysaccharide which is composed by the fructose.In 1999, for the first time from puncture the root in the alcohol extraction to sep arate Oleanic acid. And used the double wave length thin layer scanning method to determine the uneven pillar tartaric acid in to puncture in the root ontent.

化学成分研究方面文献报道极少：据报道，山刺玫根中含有内酯、鞣质、还原糖、总苷、黄酮、酚类、生物碱类、蛋白质、蒽醌等成分，而且山刺玫根中总多糖是由果糖组成的均多糖。1999年，首次从刺玫根的乙醇提取物中分离出齐墩果酸，并采用双波长薄层扫描法测定了齐墩果酸在刺玫根中的含量。

We get the steady queue length with generating function of probability and the waiting time with Laplace-stieitjes transforms.

本文主要讨论了带启动期的一般减量服务的单重休假$M/G/1$排队系统，文中将启动、休假、减量三者结合在一起，系统交替地处于休假、启动、工作状态。

After studying the MAC protocol of Ad hoc network and by modifying the Wireless Token Ring Protocol, a new uncontested Distributed Parallel Wireless Polling Access Protocol that can provide MAC QoS guarantees for Ad hoc network is presented, and the mathematical model is established by the embedded Markov chain theory and the probability generating function method. Based on it, the mean value of queue length and message waiting time are explicitly obtained.

摘要该文对Ad hoc网络的MAC层协议进行了研究，通过对无线令牌环协议进行改进，提出了一种新的具有QoS保障的无竞争的分布式并行无线轮询访问协议，并采用嵌入Markov链和概率母函数的分析方法，用限定服务规则进行了系统建模，在系统模型的基础上得到了系统的平均排队队长以及平均等待时间的解析结果。

Under the service rule that customers who first come would first get the service, we use the structure analysis method to get the stochastic decomposition of the queue length with the generating function of probability and the steady waiting time with Laplace-stieitjes transforms.

重点分析了带启动期的一般减量服务的单重休假$M/G/1$排队系统的一般结构，利用结构分析的方法，在先来先服务规则下求得稳态队长的随机分解的概率母函数和稳态等待时间的随机分解的$LST$，同时，讨论了系统处于平衡的条件及其概率含义的直观解释，进一步讨论了系统处于休假期、忙期、忙循环等状态时的各项性能指标及系统状态分布。

Methods 112 blood samples of occupationally lead-exposed workers were selected from a puddling factory in the suburb of Chengdu. An assay based on the polymerase chain reaction-restriction fragment length polymorphism technique of restriction enzyme Bsm Ⅰ was used to detect at the same time.

整群抽取成都市郊区某炼铁厂接铅作业人员112人，抽取其静脉血进行血铅、血清钙和基因多态性测定，按基因型测定结果分组分别比较其血铅、血清钙的差异，并进行血铅和血清钙的相关性分析。
