The Joseph father advantage takes a bath the number of times are not many, the approximately 23 weeks only then flush one time then to be possible, but the pet owner cannot be therefore loaf, still importantly recorded scratches every day for the dog class throws over the wool, can make to throw over the wool maintains along slides sharp; Because the Joseph bottomless wool level, throws over the wool in addition inborn along the straight relations, therefore throws over the situation which the wool very little appears ties a knot, in after dog flushing body, must thoroughly and eats Mao Mogan does, uses the unraveling to comb again combs the wool cascade is suitable, because the dog throws over the wool young, therefore in combing time then must double carefully, combs by suitable Canada, only then not Mao Shuduan, if needs, may use unraveling unrefined oil, when carding wool then did not fear that sleepy wrong with adds makes the painful dog; Because throws over the wool the fat secretion to be many, the ear easy Tibet dirt, skin also Yi Sheng to have the tinea, must therefore maintain the body clean clean.

补充约瑟爹利洗澡的次数不多，约两三星期才冲洗一次便可，但饲主也不能因此而偷懒，仍要紧记每天为狗儿流擦披毛，才能令披毛保持顺滑亮丽；由於约瑟无底毛层，加上披毛天生顺直的关系，所以披毛很少出现打结的情形，在替狗儿冲洗身体后，要彻底把毛抹乾及吃乾，再用解结梳把毛逐层梳顺，因为狗儿的披毛较幼，所以在梳理时便要加倍小心，以适当的加度去梳，才不把毛梳断，如需要的话，更可使用一解结毛油，梳毛时便不怕困错用加而弄痛狗儿；由於披毛的脂分泌较多，耳朵易藏污垢，皮肤亦易生有癣疥，所以要保持身体清洁乾净。约克夏狗是狗类型一个小狗品种，开发在19世纪在约克夏历史地区在英国。品种的定义的特点是它的小型和它柔滑的蓝色和棕褐色的外套。品种起绰号Yorkie和安置在狗小组的玩具狗部分由Fédération Cynologique国际歌和在玩具小组或伴侣小组由其他狗窝俱乐部，虽然所有同意品种是狗。一赢取的showdog和一条普遍的伴侣狗，约克夏狗也是其他品种的发展的一部分，例如澳大利亚柔滑的狗。

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。

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。

For low permeability oilfields, radial flow straight-line portion should not appear in producer measuring data during shut-in build up tests. A practical method to interpret formation parameters based on well testing data at early fillup period has been established With the application of this kind of method, ideal interpretation results can be obtained when the measure pressure data lie above and under semilog straight-line portion, and the formation parameters can be interpreted more reliably.

对于低渗透油田，在通常的关井压力恢复测试中，油井测压资料不能出现径向流直线段，针对这种情况建立了一种用早期续流段试井资料解释地层参数的实用方法，通过计算续流量利用褶积分析方法解释早期试井资料，可对实测压力数据点落在半对数直线段上方和下方的两种情况都收到较理想的解释效果，能解释出比较可靠的地层参数。

The theoretical foundation for further research is established. In chapter 6, the flow field of poppet valve and spool valve which are two kinds valve frequently used in hydraulic technique are predicated by finite element method. The flow field structure at different valve opening are illustrated by visualizing images. The effect on the flow noise and energy loss probably caused by vortexes is analyzed quantitatively, the flow channel of the valve is improved.
