Under lower potassium stress, the high efficiency ramie genotypes had higher growth potential (higher relative root dry weight, relative rootlet dry weight, relative root total and active absorb surface area), and higher relative fiber yield, decreased the negative effect of lower potassium stress on fiber quality validly.

但高效基因型苎麻低钾胁迫下仍具有较强的生长势（相对根系干重、相对细根干重、相对根系总吸收面积、相对根系活跃吸收面积较大），其纤维产量所受影响程度小于低效基因型，有效降低了低钾胁迫对纤维品质所引致的负面影响。

In other words, owners assembly is a legally decision-making body. Despite the fact that an owner's assembly is neither a legal person nor other sorts of organizations, it is of great importance as follows to upbuild and perfect this autonomic system. An owner's assembly is an effective board to ensure owners'rights.

从法律上讲，业主大会是全体业主的决策机构，虽然在我国业主大会既不是法人又不是其他组织，但是建立和完善业主大会制度仍有重大的意义：(1)业主大会能够有效地维护和实现业主权利。

For different surface roughness of electrodes and glycol concentration of glycol/water mixture, pressurized water breakdown experiments are carried out. Experimental results suggest that Mirza's formula is valid and independent of surface roughness and glycol concentration, and it is accumulative for surface polish, glycol additive, and pressurization for the capability to improve electrical breakdown strength. Moreover, the increase of electrical breakdown strength of water dielectric for surface polish is explained with bubble breakdown. Especially, highest stress of 235.5kV/cm observed in glycol/water mixture with a glycol concentration of 80% at a hydrostatic pressure of 12atm is about one time greater than that in pure water at constant pressure.

通过改变电极表面光滑程度和乙二醇浓度，分别进行了加压水介质击穿实验，证实了不同电极表面光滑程度和乙二醇浓度下Mirza关系式仍成立，抛光电极表面、添加乙二醇与加压在提高水介质电击穿能力方面具有可叠加性，将抛光电极表面、添加乙二醇与加压分别进行了比较，特别，在静压12atm、乙二醇浓度80%下，得到实测最高击穿场强为235.5kV/cm，其有效时间归一化后的击穿场强比常压下纯水的相应值提高了112.2%，运用气泡击穿模型对抛光提高水介质击穿场强进行了物理解释。

At present, Infectious Bursal Disease is widespread epidemic and results in serious damage to the poultry of China, although several kinds of vaccines are applied.

Background and objective: Rhomotoxin, the active constituent of Rhododendron molle belonging to Ericaceae, has the effects of decreasing blood pressure and slowing heart rate. These effects can exacerbate and remain 0.5-1 hour after drug withdrawal, which is prone to cause lower blood pressure even shock.

背景与目的八厘麻毒素(rhomotoxin，RTX)系从植物杜鹃花科羊踯躅成熟果实中提取的有效成份，具有较强的降压、减慢心率作用，但其降压作用在停药后0.5-1小时仍继续加深，易引起降压过度而导致休克，同时血中浓度检测困难，不易监控，临床上应用较难掌握。
