A new method of obtaining secondary electron yield and secondary Cs〓 ionization probability by detecting target current and primary ion current under Cs〓 bombardment is put forward The dependence of Cs〓 ionization probability on primary ion energy, primary beam current and substrate compositions, as well as the dependence of secondary ion intensity on erosion time during transient period has been studied The mechanisms of secondary ion emission are explained

二、提出了通过测量靶流和一次束流求取Cs〓轰击下二次电子产额和二次Cs〓离化率的方法，实验研究了一次离子能量、束流强度及不同基体对二次Cs〓离化率的影响和瞬态过程中二次离子强度的变化规律，并对发射机理做了解释。

No,the Japanese society is polite society now ,it is different from the past lawers said .at last the lawers persuade her to claim for damages to Japanese goverment ,she become to know maybe it is not the fate she should deserve .so she leave her plowland ,in her life,she never see the city .never travels by air and never have chance to see the skyscraper.in the court of Japan,she repeat telling her nightmare again and again ,she weep again and again,she was ashamed and in pain when she said, but she has to tell out just make the judge sure it really happened to her in the past.

不。现在的日本社会是文明的社会和以前不一样了律师们说。最后律师说服她向日本政府索赔。她开始觉得也许她的命运不该是她所想的那样。于是她离开她的土地，在她的一生中，她从没有机会去城里，做飞机，看到摩天大楼。在日本的法庭上一次又一次重复她的噩梦，一次又一次痛哭，她不得不羞辱而痛苦的说出来好让法官相信发生在她身上的事实。

Today's show is over, again and again every time the pyrotechnic show exciting, let me see the country's technology boom, developed.

今天的晚会结束了，一次又一次的烟火晚会一次比一次的精彩，让我看到了祖国的科技繁荣、发达。

Let me like this Why you injuring hearting of me again and again, I think I, I come round, but you in stabing me ruthlessly at my wound.

为什么你一次又一次的伤我的心，我以为我好了，我想通了，可是你却一次又一次的在我的伤口上在狠狠的刺伤我。

Regulating the control group used traditional western medicine treatment: The application of the latest "chronic congestive heart failure treatment recommendations"China cardiovascular disease magazine, 2002; 30 (1 :7-21 Recommend the most appropriate method of treatment, According to patients after hospital-based treatment of illness:① general routine treatment: rest, salt restriction, oxygen, etc.;② to the diuretic (urine dihydrochloride grams thiadiazole 25 ~ 50 mg or 20 mg furosemide, antisterone 20 mg, 1 to 3 times daily oral);③ ACEI:(captopril 625 mg, twice daily beginning);④β-receptor blocker (metoprolol from 6.25 mg daily oral dose of 1 start);⑤ cardio (digoxin 0.25 mg daily oral administration, a week after the condition of patients based on the alignment of their drug dosage or suspension).

对照组采用西医规范治疗：采用最新的《慢性充血性心力衰竭治疗建议》（中华心血管病杂志，2002；30（1）：7—21）推荐的最适合的治疗方法，患者入院后即根据病情进行基础治疗：①一般的常规治疗：休息、限盐、吸氧等；②予利尿（双氢克尿噻25~50mg或速尿20mg、安体舒通20mg，每日1~3次口服）；③ACEI：（开搏通6.25mg，每日2次开始）；④β一受体阻滞剂（倍他乐克从6.25mg，每日1次口服开始）；⑤强心（地高辛0.25mg，每日一次口服，一周后依据患者的病情，调整其用量或暂停药）。

He has abdicated government here, by declaring us out of his protection and waging war against us.

而我们一次又一次的情愿，却只是被报以一次又一次的伤害。

Although his worst accident was man-made, messing up a training jump, he had several hair-raising brushes with nature: tumbling down a glacier on the Eiger, crash-landing in a tree in India and, on his fourth balloon attempt, plunging five miles into the Coral Sea with the canopy on fire.

虽然他最差的一次事故是人为造成的---在一次试跳中搞砸了，但他有几次令人恐惧的&和自然擦肩而过的&历险：在艾尔格峰上翻进了一条冰河里，在印度，飞机撞在了一颗树上，还有，在第四次气球飞行时，带着燃烧的盖蓬，从5英里高的地方直接掉进了珊瑚海里。

Again and again they closed upon him, and again and again he hewed a clear space.

一次又一次他们逼近他，一次又一次他又杀退了他们。

Through the analysis of the distributions of cold pulverized coal concentration and the area of high concentration zone, it was concluded that the smaller the central air expanding angle was, or the later the secondary air interfused, the larger the area of high concentration zone was.

通过分析冷态煤粉浓度的分布及煤粉高浓度区域面积的大小，得到：中心管扩角越小，二次风混入越晚，冷态高煤粉浓度区域面积越大；一次风率为0.2、一次风速为15 m/s、直流二次风速为25 m/s时冷态高煤粉浓度区域面积较大，有利于降低NOx的生成；内二次风旋流开度减小较外二次风旋流开度减小对冷态高煤粉浓度区域面积的影响大；内旋流强度为1.35、外旋流强度为1.56为最佳的试验工况。
