想去美国留学，gpa是很重要的，gpa不仅反映着学生的学术表现，还与申请研究生、转学、就业、奖学金等息息相关。gpa低是件不可忽视的大事，如果因为gpa过低被开除，可就得不偿失了。

　　大学里，本科生gpa不得低于2.0，研究生gpa不得低于3.0，如果没有达到要求，则会面临开除。如果留学生想在毕业后继续申请研究生、博士进行深造，那么达到最低gpa要求是远远不够的，申请研究生需要最少3.0，博士则需要3.5以上。

　　在美国大学里，一门课的最终成绩并不是仅由期末考试成绩决定的，每门课的评分标准都不一样，而且会有多种多样的考试形式，各种考核形式所占比重也不同，最后通过加权平均法（Weighted Score）得出相应的分数。

　　补救措施

　　对于留学gpa低的同学来说，一般常见两种情况：整体学术水平低，或偏科严重。整体学术水平低的同学的通常毛病就是出勤率低、学习效率低、学术不诚信、时间观念差。有些同学清楚自己的学习效率不行但是因为在异国没有老师指导，不知道该如何是好；有些同学则是轻信代写可以帮助自己取得好成绩，这些行为都会断送自己的前途。

而偏科严重的同学是缺乏对于课程的理解，选择了一些自己不擅长不感兴趣的科目，最后拉低了自己的gpa。这时候科学专业的指导就是很重要的一件事，帮助自己选择强势学科，那么gpa肯定会回归正规。

Define of 6 Section Boom Concrete Pump Truck

The six section pump truck, as the name implies, is a product type of the pump truck. With the help of six steel arms, it creatively USES bionics technology to integrate the mechanism of human hand movement and insect foot movement into the design of concrete pump truck pump frame. It combines finite element, dynamic simulation and other advanced design methods.

Advantage of 6 Section Boom Concrete Pump Truck

The six section technology greatly improves the utilization rate and flexibility of the arms frame. Compared with the five section boom, under the same length, the effective placing height is increased by 15%, and the effective placing range is increased by 20%. Meanwhile, based on the bionics design, the initial boom is long and end boom is short. The opening space is smaller, and the booms frame is more flexible. For example: At the same height of 50M, the real casting height of six section boom is more than 4M higher than that of five section boom. the 50M six booms =54M five booms. The pump truck has a higher cost performance.

1. Structure

The pump truck adopts three-level telescopic X leg, with innovative use of sprocket + tied oil cylinder of the supporting leg drive mode. It solved the X - type leg three - level stretching technical problem. By adopting the structure of six arms, the effective height of placing can be increased. Equipped with the function of unilateral support, it can satisfy different requirements from the construction site.

2. Pumping of hydraulic pressure

The pump truck adopts the super-large square volume pumping system, and the maximum theoretical square volume can reach 200 square meters/h. The pump square volume can reach 140 square meters/h even if it adopts high pressure. This 200/140 pump unit is configured as the highest level of pump square volume of domestic pump trucks. It adopts full-automatic high-low voltage switching technology, which enables the operation of high-low voltage switching to be completed as soon as the electric control button is pressed gently. There is no need to dismantle the pipe. It is without any leakage. And the blocked pipe can be removed quickly. What’s more, the use of the latest quick change pump oil cylinder, can greatly save the time of replacing concrete piston.

3. Electronic control

For the first time, it adopts a duplex remote control with feedback display. The remote control can display a lot of pump working data in real time screen. After combining the functions of the remote control and electric high and low voltage, the machine operator can clearly see the working status. It is more convenient for the operators to timely understand the operating parameters of the pump truck, and to better complete various tasks.

When selecting a concrete pump truck, we think about our authentic development needs. The longer the dimension of the concrete pump truck boom,the longer distance and the higher peak the material can be transported to. However, if it is used for concrete construction in some narrow building site, the long boom can also not be a right thing. The long arm will not only cause value waste, but additionally make the concrete pump truck unable to be deployed in such a construction site. Therefore, in the true manufacturing process, we should consider our constructing conditions, practicality, economy, safety, maintainability, In different respects, pick out a pump truck with the appropriate concrete pump truck dimensions. We must pick out concrete pump in accordance to the local establishing and therental market conditions. Teila supplies pump trucks with a range of boom sections, consisting of four sections, 5 sections and 6 sections.

Teila is committed to providing the most valuable products and services since it was established. In order to meet the needs of clients in concrete machinery, Teila works hard to build vigorous industrial chain and ecological chain.

HOW TO CALCULATE RADIUS OF STAINLESS STEEL ELBOW?

I have my own unique views on the calculation formula of stainless steel elbow size. I hope you can learn more from the following experience.

1. 1.5 times the elbow center height = diameter *1.524, which is actually the diameter * multiple. Round the number after the decimal point of the result to an integer. For example, the diameter of 219 is 200, the center height is 200*1.524=304.8, and take 305. The diameter of 114 is 100, the height of the center is 100*1.524=152.4, take 152.

The algorithm applicable to DN100 and above elbow radius of curvature is convenient and fast to calculate.

2. Stamp height = center height + elbow radius, such as 1.5 times the diameter of 219 elbow stamp height =305+219/2=305+109.5=414.5

3. Outer arc length =(center height + radius)*3.14*2/360* degree, i.e. (stamp height)*3.14*2/360* degree, from which it can be calculated that the outer arc length of 90-degree elbow = stamp height *3.14/2.

4. Internal arc length =(center height - radius)*3.14*2/360* degrees.

5. Elbow length = elbow center height *3.14/2* elbow outer diameter/pipe diameter +(pipe wall thickness *3)+ machining allowance, such as using 180*8 pipe cutting, push system 273 elbow, with the above formula can be calculated, blanking length =381*1.57*273/180+24=931.22mm+ machining allowance.

As a professional 180 degree elbow supplier, Huanshang steel welcome international customers come to visit and order.

This separator absorbs American technology and developed by our company which is the newest style separator of our company at present.

The separator's working principle: The used abrasive from the bucket elevator is delivered by the screw to the upper separation area. The screw separates it evenly in the separation area along with the separator, forms a pill sand flow curtain-like a waterfall. At the same time, the blower of dust collector separates the projectile, molding sand, metal oxide skin fragment, stave projectile and dust in the flowing curtain through convulsion

on separator gusty area and using gravity dry separation way which will flow in the bunker after the second filtration by the bottom strainer and store up for the next circulation. The best separation effect of separator depends on the adjustment of the flow control board position of dry separation area, the adjustment of adjustment board position on filtering panel, adjusting the reed valve wind amount of air hose to realize. It can get good separation effect if the adjustment is reasonable which can keep the separation efficiency above 99.5%.
