Secondly, there are bigger value at risk by Historical Simulation Method of risk-factors free, represented investitive net value are NT 10,000,000, maximum loss of 5﹪probability will greater than NT 2,816,827 or NT 2,344,946. So used considering VAR－Bootstrap of risk factors were more appropriated model, because model of considering risk factors were able to accurate estimate reality value at risk.

二、以未考量风险因子之历史模拟法及GARCH－拔靴法所估计风险值较大，表示投资净值一千万，有5﹪的机率可能的最大损失会大於2，816，827元或2，344，946元，因此，考量风险因子之VAR模型－拔靴法为较适当之模型，因有考量影响风险之因子，较能准确估计出实际之风险值。

Methods: Fifty-fix adolescents were chosen and divided into first premolar extraction and nonextraction groups, with 30 and 26 patients respectively. The pretreatment and posttreatment panoramic radiographs were taken. The indexes of third molar eruption space, distance from third molar to occlusal plane and the length of mandible were measured and analyzed.

选择56例上下颌第三磨牙均存在的患者进行方丝弓正畸治疗，按照第一前磨牙拔除与否分为拔牙组（30例）和非拔牙组（26例），利用术前术后曲面断层片对患者上下颌第三磨牙萌出间隙、第三磨牙与胎平面的距离以及下颌长度进行测量分析。

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

From the process point of view of the carton box design optimization normally includes the following aspects: first, the material on the carton with process improvement, selection of appropriate materials to production, focused "" five to three; the other is in the efficiency of the process and equipment to learn about existing equipment maximum productivity, production quality of the product, so that different box with the appropriate processes and equipment to produce; third, the design process of process improvement, strengthening the designers and technology staff communication so that the design of the product to be able to give full play to the advantages of enterprise resources; the fourth is to strengthen the carton design-time costs, such as from corrugrted, triangulateration paerboard, and so on through the finishing processes, mainly of the paste, cut shape processed into packaging, and sheathed, and so on, instead of EPS foam, and the use of adhesive paper box instead of nails made of cardboard, prevent moisture transport environment of a nail the appearance of secable and tocommandthe.

从工艺角度优化纸箱箱型安排凡是包含一下几个方背：一是差纸箱配材工艺鼎陈，采取不合的质料来出不销，轻点突不入&五改不一&的收益；二是工艺历程和摆撤的鼎陈，不懂现有摆撤的最不小的出不销本领、出不销不销物的度度境况，使差别的箱型用不合的历程和摆撤来出不销；不一是安排工序的工艺鼎陈，放松安排职员和工艺职员的相同，使安排的不销物没干系充脚阐发企业的资源劣势；第四点不离是放松纸箱安排时不败本的筹算，比如拔取宝瓦楞纸板、边角纸板等通功后道加工工序主给为剥离、焊接不败型等加工不败包拆座、衬垫、护套等，替代EPS泡沫，还有搁置粘合纸箱代庖铁钉纸箱，避免输送洋湿润的境况造不败铁钉生锈带来的表背和搁置上的感化。

POD activity presented the tendency of increasing-decreasing-increasing and the first peak appeared at seven-leaf to jointing, the second peak appeared at silking to grain and the lowest value emerged at tasseling.

POD活性在整个生育时期呈现高-低-高的变化趋势，第一峰值出现在7叶期至拔节期，第二峰值出现在吐丝期至灌浆期，最低值出现在抽雄期。

Cited Pistons pull vent valve 10-valve piston cited the role of pulling out are seized cylinder piston rod, when its mild in China emerged after the main hydraulic cylinder rod cavity and there is no cavity under the pressure dropped, so that the main hydraulic cylinder in motion the process of increasing resistance to the main pump to increase the load, resulting in engine speed when pumping declining situation.

3活塞引拔阀内泄活塞引拔阀10的作用是拉出检缸活塞杆，当其出现轻度内泄后，主液压缸无杆腔和有杆腔的压差下降，使主液压缸动作过程中阻力增加，使主泵负荷加大，导致泵送时出现发动机转速下降的现象。
