It comes form vibration signal that obtained by monitoring in two mutual vertical direction on one cross section of the axletree or axes neck.

它可以通过振动位移和激振力的相位的变化来判断转子的临界转速；当挠性转子由不平衡力引起振动时，在不同的转速下有不同的振型，根据不同的振型对转子进行有针对性的平衡；另外根据检测到的轴心轨迹图形状，可以分析出造成振动的具体原因，根据不同的原因进行防振和减振。

Typical accident-causing" theories includes Heinrich" s Domino" s theory, its development by Bird, Adams and other people, progress of which is that it is deficiencies of management system that are the root cause in accident causation sequence. This is author" s idea resource and main method to produce the water traffic accident-causing theory . in addition, uncontrolled transferring of energy theory, applies widely in safety management scheme for water traffic; human error accident model can be used to analyze causes of collision accident and to take preventive measures; perturbation theory and multilinear event sequencing method is a very useful investigation method to water traffic accidents. All of these theories have contributed to the development of water traffic accident-causing theory. As to orbit intersecting theory, the paper thinks it extension of Domino s theory, although it exists independently.

有代表性的事故致因理论有海因里希因果连锁理论以及博德、亚当斯等人对该理论的发展，这些发展的主要进步是突出了管理缺陷是事故因果连锁中的基本原因，是本文分析和发展水上交通事故致因理论的主要思想来源和方法论；能量意外转移理论，广泛的应用在水上交通安全的各项具体管理制度中；人失误事故模型能用于指导对碰撞事故的原因分析和预防；动态变化理论及多线性事件连锁论对指导事故调查是较好的分析方法；轨迹交叉理论虽然以独立的理论形式存在，但本文认为其实质仍然是因果连锁理论的发展。

It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.

发现：TEA作为助催化剂时产生低分子量产物的活性中心易于活化，且体系中具有活性的活性中心有4～5种；TIBA易于活化产生高分子量的活性中心，基本上不能活化产生低分子量产物的活性中心；MAO对产生中等分子量产物的活性中心活化能力较强；在TEA-TIBA混合物体系中，TEA和TIBA各自对活性中心的作用表现为明显的互补现象，各活性中心的相对强度随着两种助催化剂之间的比例改变呈现渐次变化，其中产生高分子量产物的活性中心的相对活性(来源：c5AB3fC论文网www.abclunwen.com)与TIBA的浓度有明显的正相关性。

Overall, first half of 2004 property sell the house, there are the following aspects of performance: 1 is the large and small sales offices overcrowding: whether new or old disk plate, whether it is the city's top luxury or ordinary residence, whether it is suburban gardens or townhouse, large and small sales offices deserted last year, one change there overcrowding situation.

总体而言， 2004年上半年物业销售的房子，有以下几个方面的性能： 1是大和小销售办事处人满为患：是否新的或旧的磁盘板，无论是城市的最豪华或普通住宅，无论是郊区的花园或住宅楼，大型和小型的销售办事处遗弃去年，有一个变化的拥挤状况。

It was found that 0.25%o potassium sorbate produced a positive inhibition against short G+ spore bacillus with a concentration less than 5xl04cfu/ml. A concentration less than %o potassium sorbate hardly exerted a complete control towards short G- plump bacillus having a population density of 5x104cfu/ml. It was proved that use of l% potassium sorbute never controlled the growth of G+ coccus, G~ spirilla and enterobacter with a population density of 104cfu/ml. 1mmol EDTA completely controlled the growth of G+ short spore bacillus and G+ coccus whose cell density was 5xl04cfu/ml. A level of lmmol EDTA showed a limited inhibition against the growth of G- spirilla with a population density of 105 cfu/ml. However, a level of 10mmol EDTA completely controlled the growth of the G- spiral bacteria having a population density of 105cfu/ml. lOmmol EDTA produced a very significant control towards the growth of G"" plump short bacillus with 105cfu/ml. 20mmol EDTA showed a remarkable inhibition against the enterobacter with a population density of 105cfu/ml. Different concentrations of nisin including 25mg/mL, 50mg/mL, 75mg/mL and 100mg/mL were used as bio-preservative to examine its effects against the growth of all strains leading to the spoilage of fresh mutton meat. It was seen that there was a big difference in nisin's concentrations in inhibiting the spoiling bacteria. Generally speaking, as more as 75mg/mL of nisin significantly inhibited the growth of G+ short spore bacillus, G-plump short bacillus, enterobacter, G'spiral bacteria and G+ coccus having a population density of 105cfu/ml.

分别运用山梨酸钾、EDTA和Nisin对7种主要引起羊肉腐败的微生物进行了抑菌实验，结果显示，0.25‰以上山梨酸钾能够有效抑制5×10~4 cfu／mL以下的革兰氏阳性短芽孢杆菌的生长；1‰以下的山梨酸钾不能完全抑制5×10~4 cfu／mL革兰氏阴性粗短杆菌的生长，对10~4 cfu／mL革兰氏阳性球菌菌株、革兰氏阴性螺旋菌菌株和肠杆菌菌株抑制效果不太明显。1mmoL EDTA能完全抑制住小于10~5 cfu／mL革兰氏阳性短芽孢杆菌菌株、革兰氏阳性球菌菌株的生长，能明显的抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株生长，对10~5 cfu／mL的革兰氏阴性螺旋菌菌株有一定的抑制作用。10mmoL EDTA能完全抑制住10~5 cfu／mL革兰氏阴性螺旋菌菌株的生长；能明显抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株的生长，而20 mmoL EDTA能很明显抑制10~5 cfu／mL肠杆菌菌株的生长。25mg／mL、50 mg／mL、75 mg／mL和100 mg／mL的Nisin几乎对所有引起羊肉的腐败菌有抑制作用，但抑制程度不同，抑菌活性有一定的变化。

Interaction of TNT with intact human erythrocytes leaded to depletion of GSH. drop of ghost SH and obvious inhibitions of 〓-ATPase and 〓 active transport. However, exposure of inside-out vesicles without Hb to TNT did not show observable change of 〓 active trans- port, suggesting that the presence of Hb is necessary for TNT to disrupt 〓 transporting function of erythro- cytes.

TNT与完整的人红细胞相互作用后，细胞内GSH水平和红细胞膜SH含量均有不同程度的下降，与此同时，红细胞膜〓-ATPase活性和〓主动转运过程均有显著的抑制，但TNT与去除血红蛋白的膜翻转泡（inside-out vesicle）孵育，则红细胞膜〓主动转运未发生明显变化，表明TNT对红细胞膜〓主动转运的抑制作用须以〓的存在为前提。

While different kinds of poker games are played at the World Series, the main game is a variation called Texas Hold'em. Each player is dealt two cards ("hole cards"). Then, five more cards are dealt in the middle of the table and are shared by all the players ("community cards"). The best five-card poker hand wins.

世界大赛中虽然有不同的扑克牌游戏，主要的游戏是一种称为&德州，等一等&的扑克牌变化玩法，每个选手发给两张牌﹙面向下的牌﹚，然后再多发五张牌﹙共同牌﹚在桌子中央给大家，在五张牌中至少有一对点数相同的牌、而且牌型分数最高的人赢。

With the time of applying manure increasing, the concentrations of HAC-soluble form and oxidisable form were decreased, the concentrations of reducible form and residual form showed increased trend, the trend of compost manure treatment and swine manure treatment were same.

Although most communities have different structural requirements, we can have the drawings engineered for your local structural engineer to review and specify changes where necessary.

The results indicate that MM5 has effect on predicting the strong clear-air turbulence, but no effect on predicting the thunder storm. The beginning and ending time, strength variation tendency and wind direction of the strong clear-air turbulence can be forecasted well by mesoscale model.

结果表明，中尺度模式对雷雨大风基本无预报能力，但对晴空系统性大风有很强的预报能力，模式可以对晴空系统性大风的出现时间、强度变化趋势和风向提供较准确的预报，对晴空系统性大风的结束时间也有一定的预报能力。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
