Methods: In this series,coronary heart disease was proven by clinic,electrocardiogram and selective coronary arteriography.Causes of 30 cases of PICAS were acute coronary occlusion in PTCA (2 cases),coronary arterial dissection (1 cases),preventing coronary arterial restenosis after PTCA (18 cases),coronary arterial restenosis after PTCA (4 cases) and acute myocardial infarction (5 cases).Thirty cases of SCAG were performed by Judkins method.

材料和方法：本组病例均经临床，心电图和选择性冠状动脉造影证实为冠心病。30例经皮冠状动脉内支架植入术的原因有经皮腔内冠状动脉成形术中发生急性冠状动脉闭塞2例，冠状动脉夹层1例，为防止PTCA术后再狭窄18例，PTCA术后再狭窄4例，急性心肌梗塞5例。30例SCAG均采用Judkins法。

These results indicate that it can availably prevent mistake judge and poisoning affair by observe animal appearance, behavior and liver, lung, kidney and scrofula firstly, to estimate whether they are exceptional, then it is better to eliminate questionable body, and to make last measure by ELISA.

上述结果可以用于屠宰过程，通过观察动物是否发生体态、行为的异常和肝脏、肺脏、脾脏、肾脏、淋巴结等组织器官的病理变化，剔除可疑胴体，再辅以ELISA检测，能有效地防止漏检错判和中毒事件的发生。

Slack water deposits are indicators of water level and age of paleoflood. They can be identified using Quaternary Period geology and hydrology, and can be aged using radioactive isotopes or other methods.

平流沉积物是洪水水位和发生年代记录的载体，利用第四纪地质学和水文学可以把它发掘出来并用放射性同位素或者其它断代方法测定它发生的年代，再通过断面恢复，进行流量推求，这就是古洪水研究。

The keystone of this device as follows : input three phase AC power supply of 380V±15%, become DC after primary full-bridge commutation wave filter, convert high frequency AC pulse of over 20KHZ using IGBT inverter module, become DC power supply for the usage of producing ozone after step-up of High Frequency Transformer and commutation of quickness rectifier tube and reactor.

高频高压臭氧发生装置的基本原理是：输入380V±15%三相交流电源，经初级全桥整流滤波成为直流，通过IGBT逆变部件，转换成20KHZ以上的高频交流脉冲，再经高频变压器升压，最后由快速整流管、电抗器整定为可供发生臭氧用的直流电源。

Discovering passage of event happened by tracing along terminal point of event on probability tree, utilizing multiplication formula and addition of probability again, the probability of an event may be caculated and some problems that students grasp with difficulty and make easily mistakes can be solved.

用概率树法求事件发生的概率，只需在概率树上沿事件的终点向前回溯，便可以发现事件发生的通道，再利用概率的乘法公式和概率的可加性，就解决了概率论中学生很难掌握的、容易出错的问题。

Adenosine was used as the raw material, dissolved in triethyl phosphate and then esterified with thiophosphoryl chloride under 0~5℃ for 8h without water and oxgen, in alkaline condition provided by 2,6-dimethylpyridine, introducing thiophosphoryl ester to adenosine.Then superfluous triethylamine was added and reacted under 5℃ for 1h to synthesize rough 5'-AMPS.The unpurified product was appled to a DEAE Sephadex A-25 column and eluted with triethylammonium bicarbonate.

用腺苷为起始原料，溶解于磷酸三乙脂中后，在无水无氧环境中及2，6-二甲基吡啶提供的碱性条件下与三氯硫磷以0~5℃下发生酯化反应8h，将硫代磷酸酯引入腺苷，然后再与过量三乙胺在5℃下反应1h，合成粗产品，再用碳酸氢三乙胺作洗脱液，过DEAE Sephadex A-25凝胶柱纯化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
