This paper, based on typical both way interface, shows an example of full-duplex parallel communication interface with CPLD.

从介绍典型的双向并行接口入手，给出基于CPLD的全双工并口的设计实例，并讨论了通信过程中握手信号的变化，通过对调试过程中遇到问题的分析，给出改进后的设计，提出了一个切实可行的高效的全双工并口的设计方案。

Methods: Fifty rabbits underwent left tube ureterocutaneostomy as a method of urinary diversion, all rabbits were divided randomly into five groups: the flushing group perfused immediately after ureterocutaneostomy, and the intrapelvic pressure is 60, 80, 100, 120 cmH2O, but the sham operated group didn't flush. Urinary albumin were examined every day after operation, we also got pathological examination of nephridial tissue continually.

分别建立左侧输尿管皮肤造口的动物模型：健康家兔50只，随机分为5组（每组10只），假手术组只造瘘不灌注，灌注组输尿管造瘘后立即行逆行灌注，灌注压力分别为60、80、100、120 cmH2O(1 cmH2O=0.098 kPa)，术后每天留取尿标本定量测定尿白蛋白，连续取肾组织行病理检查监测兔肾形态学改变。

The proximal jejunum of the graft was anastomoscd to that of recipient, and an jejunostomy was created by exteriorizing the distal end of the donor jejunum with the recipient distal jejunum anastomosed to the side of the graft blow the stoma.

肠道重建采用切除受体部分回肠，将供肠近端与受体肠近切端端端吻合，供肠远端与受体肠远切端端侧吻合后把供肠远端拖出，腹壁造口的方法。

Three species: Ancistrum crassum, Ancistrum japonicum and Boveria subcylindrica were morphologically investigated based on living observations, protargol impregnation and wet silver impregnation techniques.

摘 要 报道山东沿海贝类鳃表及外套腔中共栖的3种触毛亚目盾纤类纤毛虫：厚鱼钩虫、日本鱼钩虫及亚桶形后口虫。

A paper of the membership card after surface processing take various forms and can be coated gloss method, or you can make the calendering or plastic mulch, etc.

纸制口的会员卡制作后表面加工方式多种多样，可以采用涂布光油方法，也可以进行压光或覆膜等方法。

The latency of the waves of SEP or MEP is extracted. But it still is the best in all. The control group is the worst of all. The wave can be found again after the spinal cords are hemisectcd in control group. 5.. Seen from the immunohistochemistry of NF, Schwann cells can promote neural dendrite outgrowth toward the area of hemisected spinal cord.

神经纤维的兔疫组化染色脊髓半切损伤后，经NF的免疫组织化学技术染色显示：移植雪旺细胞可以促进神经纤维向脊髓损伤区域生长，抗体封闭 LI后神经纤维的生长受到抑制，再生神经纤维数相对减少，这从免疫组织化学方面说明口对神经再生具有影响。

This paper using the FEM software Marc, for the 50 and 60 degree V groove of flat plate butt joint simulate the one-layer and three layers welding, finish each welding and cooling it down to room-temperature then start the next welding true represent process and get the temperature field, residual deformation and welding residual stress, according to the theory analysis and empirical equation verified the temperature field and residual deformation all correct, comparison with experiment verified the welding residual stress regularity and correctly.

本文利用有限元软件Marc，对开60°和50°V型坡口的平板对接接头，动态的模拟了单层单道打底焊，焊完一道后让试件冷却到室温以及单层单道满焊，每焊完一道后让试件冷却，然后再焊下一焊道，道间温度≤200℃，在以此为初始边界条件下开始下一道的焊接，真实的再现了焊接过程，得出了温度场，残余变形和残余应力场的分布规律，根据理论分析及经验公式验证了温度场以及残余变形的正确性，角变形的大小，这些结果与数值计算相吻合。通过与实验测得的残余应力进行比较，验证了焊接残余应力的分布规律及模拟的正确性。

The results show that:(1) Light-calcined MgO powders prepared with nature magnesite or Mg2 both are of face-centered cubic structure.

结果发现：水化前后得到的都是面心立方晶体结构的MgO，但水化前得到的轻烧MgO中仍存在官能团CO32-的残留物，而水化后得到的轻烧MgO中不存在CO32-，而且颗粒变得较易破碎，大大减少了细磨时间；再者，水化后的轻烧MgO活性较高，加上Mg2在分解过程中残留的水分对MgO 的烧结起催化作用，因此，使其经高温锻烧制得的烧结镁砂的开口气孔率由水化前的2.0%下降到0.6%，闭口气孔率由水化前的6.1%下降到2.8%，体积密度由水化前的3.29g/cm3提高到3.46g/cm3。

Ashore, I喘着粗气, big mouth breathing the air, not later dare to go by.

上岸后，我喘着粗气，大口的呼吸着空气，过后再也不敢下海了。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
