RESULTS Xiaocuoling at the concentration of 2.5、5.0、10.0g.kg-1 obviously inhibited the paws swelling induced by carrageenin in mice and the granuloma with cotten pellet in rats,decreased the penetration of blood capillary caused by histamine,increased the activity of peroxide hydrogenase in RBC,reduced the reaction of the torsive body induced by acetic acid in mice,and had no effects on the serum concentrations of testosterone of serum in male rats.

结果：消痤灵颗粒 2.5、5.0、10.0g.kg-1可显著抑制角叉菜胶所致的小鼠足趾肿胀和大鼠棉球肉芽肿，降低由组胺诱导的小鼠皮肤毛细血管通透性的增加，提高红细胞过氧化氢酶的活力。对乙酸致小鼠扭体反应有抑制作用。对雄性大鼠血清睾酮含量无影响。

AlN MSM devices were fabricated on AlN epitaxial thin film deposited on GaN/Sapphire substrates using helicon sputtering system at the low temperature of 300°C. The device characteristic was found to be improved by in situ metallization of Al electrodes. The extremely low dark current (1.39pA at 20V), the ideal factor (1.0125) and the Schottky barrier height (0.916eV) are superior compared to those of AlN MSM in the literature. When the device was illuminated by the 150W D2 lamp, the ratio of the induced photocurrent to dark current is more than 2 orders of magnitude. The illumination effect also shows the linear relationship between the radiation power and the photo current for the MSM devices, indicating the potential applicability for deep UV sensors.

氮化铝金属-半导体-金属光侦测器则是用In situ metallization制程，利用低温回旋溅镀法在氮化镓/蓝宝石基板上沉积之氮化铝，再直接溅镀金属铝作为指叉电极，比较目前文献制作出来的氮化铝MSM元件，可得到很好的元件金半接面之理想因子1.0125，算出萧特基能障高度为0.916eV，并有很低的暗电流为1.39 pA，提升了元件的特性，使用150 W氘灯入射，光暗电流差距可到两个order，且元件之光电流与入射光功率呈线性，显示所制作之氮化铝MSM元件，很适合针对深紫外光波段侦测。

It resembles the psilophyte Rhynia from the Rhynie chert of the Devonian period.

库克逊蕨属有无叶的纤细二叉分支状的茎，成熟孢子囊和孢子充分角质化，该植物与在泥盆纪 Rhynie 燧石中找到的裸蕨中的羊角蕨属很相像。

A driven axle with linkage pin is embedded in it via bearing, ratchet wheel and fork locating sleeve. A reset spring mechanism composed of spring, spring holder and top ball is installed on the top of driven axle.

它具有一呈阶梯套型的主动轴，经轴承、棘轮和拨叉定位套嵌装一带有联动销的从动轴，该从动轴的上面设置有由弹簧、弹簧座及顶珠构成的复位弹簧机构。

However, the storm-petrels of the Western Pacific are poorly known (which is a fact stressed in the Onley/Schofield " Albatrosses, Petrels and Shearwaters " guide) and I believe that all of these birds are actually Swinhoe's Storm-petrels.

然而，人们对西太平洋的海燕所知很有限（这在 Onley 和 Schofield 所著的『信天翁、海燕、水剃』导览一书中有陈述），我相信这些鸟（ LB 注：应指这趟行程看到的初级飞羽基部白色的海燕）事实上都是黑叉尾海燕。

The spacious work platform and high beaning capacity have enlarged the aerial service scope of the platform and make it suitable for several persons working together simultaneously.

它的剪叉式机械结构，使升降台起升后有较高的稳定性，宽大的作业平台和较高的承载能力，使高空作业范围更大，并适合多人同时作业。

This mechanism has the benefit of allowing high levels of Cx while remaining highly sensitive to small changes in charge coupling due to touch; the circuit permits the designer to create very large, highly interdigitated touch keys that are very sensitive.

这种机制允许有高水平的Cx的利益，同时保持高度敏感，负责耦合的微小变化，由于接触，电路允许设计人员创建非常大的，高度叉触摸键非常敏感。

In the components two jaw spot has two mm holes, with installs rolls the real bearing and is connected with the cross axle, plays the rotary shaft coupling role.

零件的两个叉头部位上有两个Φ mm 的孔，用以安装滚真轴承并与十字轴相连，起万向联轴节的作用。

Parties were able to elude each other for the space of half an hour without going beyond the "known" ground.By-and-by, one group after another came straggling back to the mouth of the cave, panting, hilarious, smeared from head to foot with tallow drippings, daubed with clay, and entirely delighted with the success of the day. Then they were astonished to find that they had been taking no note of time and that night was about at hand.

这条主通道宽不过八到十英尺，每隔几步两旁就有高耸而又狭窄的通口叉出去，——因为麦克道格拉斯山洞是个通道交错的大迷宫，不知通往何处，有人说你在这错综复杂的裂口和崖缝中一连走上几昼夜都找不到山洞的尽头；你尽可以一直往下走，往深处里去，大迷宫套小迷宫，一个也走不到头。
