查询词典 time-base control

To give the definition of the mass concrete and to concrete\'s cracks together with practical meanings of control ,and give a brief review on the research in the field at home and abroad, at last, methods to control temperature crack of the mass concrete from several aspects such as design measures,concrets material, construction schedules.etc are summed up; To explain the physical mechanics of the concrete and computing methods-Difference Method and Finite Element Method, and illustrate the application of their specific methods repectively;Several temperature factors that can influence the temperature stress of mass concrete baseplate are analyzed. The influence degree of temperature factor can be got through the ANSYS simulation computation the control of temperature can control the temperature stress, consequently control the temperature crack of mass concert baseplate; through the influence of the crack resistance ability of mass concrete baseplate which takes the reinforcement as a part is analyzed. By ANSYS simulation, the best suited volume ratio of reinforcement is found out, at same time the layout of reinforcement with the same volume ratio can also affect the resistance ability of mass concrete baseplate. Sum up of above analysis, anti-crack function of steel bar in early mass concrete baseplate is obvious, so it\'s necessary to consider beneficial effect of construction steel bar in research of temperature control on mass concrete baseplate.

On the flexibility of tactics after more than a pass is flexible and I am not here to say, I will talk about the main points: 1, if a D does not increase blood bears do not return to open the same violent avoid opening kill, and disappear, lost to blind DZ, equipment can only say that a bit far worse; 2, if the Bears D to open violent response, you should not continue to attack and should attack you = reply to the HP, do not control, even if not control him, and he will not stay in the number of anger, not much damage output; Bears D on a human five seconds halo skills CD for 30 seconds, if the DZ had tried to avoid being hit, the general gambling Bear D will not take the skills, if HP Xiong D is less than 50% when using this skill, take one's time to lift the recommendations to see if he is a change or continue to bear form, the early lifting of the Bears D changed their tactics, then, and fight back, you will be injured, if he changes were increases in blood or take the skills, you will be the speed of response, and who is in the form of the XD is too fragile, and this time a counter-attack by DZ, the basic die is disabled. 3, proposed by the drug for the treatment and slow down (do not underestimate the slowdown, though XD turned the speed of the lifting of restrictions on DEBUFF, but turned when it is more dangerous, and at the same time suggest that a variety of turned to see Wang XD) Of course, bring their own drugs slow down the damage can be free with the.

之后的战术就灵活多了，打发是灵活的，这里我就不继续说，我就说说要点：1、如果一个熊D不加血不用开狂暴回复一样杀掉开闪避、用消失、丢致盲的DZ，只能说装备上差的有点远了；2、如果熊D开狂暴回复，你就最好不要继续攻击了，应为你的攻击=回复其HP，也不要控制了，就算不控制他，他怒气也不会留多少，伤害也输出不了多少；熊D就一个晕人5秒的技能CD为30秒，如果DZ开了闪避，一般熊D不会赌博的放这个技能，如果熊D是HP少于50%的时候用这个技能，建议不忙解除，看看他是变人还是继续熊形态，早早的解除的话熊D改变战术，和你拼命，你会很受伤，如果他变人加血或者放技能了，你就要速度反应了，人形态的XD是在是太脆弱了，这个时候被DZ一个反击的话，基本不死也就残废了。3、建议上毒为减治疗和减速（别小看减速，虽然XD变身解除限制速度的DEBUFF，但是变身时候是比较危险的，同时建议各位XD看看各种变身宏）当然了，毁伤自带减速毒就可以自由搭配了。

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是*模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的*模，加工时把工件毛坯和*模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着*模边缘作轨迹移动，从而切割出与*模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95％以上的电火花线切割机床都已采用数控化。
