此病主要为害梨树的骨干枝，发病初期树皮外表无明显病斑，从皮孔。叶痕。伤口等处渗出锈色水珠或有锈水忽然渗出，此时只有用刀削开皮层，才可见皮层呈淡红色并有褐色小斑或血丝状条纹，腐皮松软充水，有酒糟味，内含大量细菌。

It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.

研究结果表明，Pd-Co/活性炭催化剂是目标转移加氢反应的最适宜催化剂，Pd-Co/γ-Al203效果也较好，而硅胶和硅藻土由于表面酸性较强，容易造成生成聚合物而堵塞催化剂微孔、使催化剂迅速失活；此外，添加Bi、Ce、Cu等助剂时对活性并无改善作用，而添加La和Ba助剂时可使Pd的催化活性有所提高，效果最好的是Co助剂，尤其是先浸渍Co的Pd-Co/C催化剂，原因是Co占据了活性炭的微孔、覆盖了某些对目标反应不利的官能团，使其活性和选择性都有较大幅度的提高。

Diagnostic characters for the recognition of species include the presence or absence of pectoral fin, the position of dorsal fin origin, gill opening, anus, nostril opening and eye, the cirri present or not, the dentition type, the body coloration, and th

一般依据胸鳍的有无或发达程度，背鳍起点、鳃孔、肛门、鼻孔和眼等的相对位置，颌的发达程度和颌上是否具须，齿的形状和排列方式，身体的斑纹，以及头部和体侧的侧线孔数目等进行鉴别。

The point is very important for a normal tone , which is that you should keep breath of your sound hole, otherwise, the sound you blow is not exact and it was harsh for audience.

按孔部位 part of press hole 要吹出一个正常的音，有一点是必需做到的，凡要求关闭的音孔是不能漏气的，一丝都不能漏，否则，发出的音则不准确，让人感觉刺耳不实在。

Even with a smaller battery than the contenders around it, the Milwaukee was a close third-fastest in our speed test at 18.8 seconds per hole and also was a very close third in our battery-duration test with 22.5 holes.

即使有一个比它周围的竞争者较小的电池，密尔沃基是一场势均力敌的第三个最快的速度测试，我们在每孔18.8秒，也是十分密切的第三个我们的电池与22.5孔时间的考验。

Two kinds of mosquitoes carry chikungunya fever. One is called Aedes albopictus, or Asian tiger mosquito. It has been reported in many European countries including France, Belgium, Spain and the Netherlands. It also lives in the southern United States.

Experimentally, multi-pores are observed on leukocyte lysed with 3D electrodes and just single pore with planar electrodes. This is believed to be due to more uniform electric field of 3D electrodes than that of planar electrodes. Intracellular elements are extracted through the membrane as observed by increased intensity of Trypan blue when diluted by saline solution. We also demonstrate the lysing percentages at same flow velocity to explain the performance of 3D electrode is superior to that of planar electrode.

在实验方面，可发现细胞在3D 电极的形况下，是有多个破孔出现，有别於在平面电极的单个破洞，也发现当细胞出现破孔时，经由Trypan blue的辅助观察以及在食盐水稀释情况下，细胞内液是往外流出的，另外由裂解比率的结果，3D电极也是优於平面电极。

From all of the above, UV Resonance Raman spectrum, as a new spectroscopic technique, is very helpful for us to further understand of structure and crystallization process of zeolites.
