"This little plastic and rubber self-retaining retractor enables one to do the procedure through a very small incision, without traumatizing the abdominal wall by placing metal self-retaining retractors on the rectus muscles and then pulling them apart with force," explained Dr. Glasser, noting that most postoperative abdominal pain is due to such trauma.

Glasser医师解释指出，这种由塑胶与橡胶所制成的小型牵开器，具有自动固定的功能，藉此可以经由很小的切割口来进行手术；在直肌上，藉由可自动固定的金属牵开器作撑开的动作，可以避免对腹腔壁造成伤害；而一般手术后的腹部疼痛，就是来自手术时对腹腔壁的伤害。

The thesis discusses three eigenvalues individually and explains the pressure wave propagation of three modes, includes wave speed, wave decay and energy distribution.

Garibotti feels that the future of Patagonia alpinism lies not in link-ups or traverses but perhaps in alpine style repeats of the inmense routes of the 1980s, such as Silvo Karo and Janez Jeglic's Cerro Torre South Face or their Devil's Directissima on the East Face.

Garibotti 认为在以后巴塔哥尼亚登山技术中，不要仅仅着眼于各个山峰之间的连接点，而应该多以阿尔卑斯登山方式攀登像80年代开辟的那些线路，像 Silvo Karo 和 Janez Jeglic 开辟的 Cerro Torre 峰南壁路线或东壁的&魔鬼的 Directissima&路线。

超高真空的除气不只是抽出残存在真空容器内的大气，而是进一步排除来自于容器壁的气体杂质，影响真空度的主要因素是等离子体放电初期从真空室器壁逃逸出来的杂质粒子。

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。

The existence ofpolar nanoregions dramatically influences the extrinsic dielectric nonlinearityof paraelectric phase. 5 Slow relaxations of field induced piezoelectricresonance of paraelectric barium stannate titanate were observed after eitherapplying or removing a DC bias field. This phenomenon is attributed to slowspace charge dipoles formed by injected homocharges and validated by theobservation of a negative piezoelectric constant. Isothermal study ondielectric constant and discharging current after application or removal of astep field were performed. The relaxation laws in ferroelectric andparaelectric phases are different. The transportation of homocharges arebelieved to be responsible for the strong relaxation behavior in paraelectricphase. Domain wall can trap space charges thus the relaxation in ferroelectricphase is relatively weak. Abnormal phenomena, such as slim-waisted hysteresisloops, abnormal C-V curves and clockwise reversible hysteresis loops observedin barium stannate titanate ceramics, were attributed to pinning of gatheredpoint defect on domain walls.

5研究了直流电场施加和撤除引起的钛锡酸钡顺电相场诱压电谐振慢弛豫现象，认为这是同极性空间电荷注入形成空间电荷慢偶极子导致的，观察到的负压电常数证实了这个观点；研究了等温条件下阶跃电压作用下介电常数和放电电流的慢弛豫现象，发现钛锡酸钡陶瓷的铁电相和顺电相呈现不同的宏观性能时间依赖规律，认为是同极性空间电荷的输运过程导致了顺电相样品呈现强的弛豫行为，铁电相中存在畴壁捕获空间电荷的机制因而其弛豫行为较弱；研究了钛锡酸钡陶瓷中束腰电滞回线、反常 C-V 曲线和顺时针可逆电滞回线等反常现象，将其归因于点缺陷的聚集对铁电畴畴壁的钉扎作用，多次电场循环有助于解除这种钉扎状态，减弱反常特征。
