1 For instance, improvement in mechanical efficiency is very slow.

2 Based on the theoretical analysis, the expressions of mechanical efficiency, hydraulic efficiency, cubage efficiency and overall efficiency for pump and pump set are given.

3 This paper puts forward some methods of solving mechanical efficiency of tackle-block, hoping to help students break through difficulties.

4 A new method to determine mechanical efficiency of diesel engine by acceleration deceleration method under non external load is proposed.

5 The volume efficiency, mechanical efficiency and total efficiency of a two-screw multiphase pump were investigated in the case of pumping water-air mixture.

6 Mechanical efficiency obtained by the new method is compared with that obtained by conventional individual cylinder fuel cut method and a good agreement is achieved.

7 The functions of temperature index and the mechanical efficiency in the formula must be taken in consideration.

8 For the mechanical efficiency of gold is, per se) its ratio to the credit built on it.

9 The problem about mechanical efficiency of tackle-block is the key point in junior high school mechanics and also the difficult point.

10 With lightweight, durable, high mechanical efficiency, safe, reliable, flexible performance characteristics of the operation.

11 In order to get the high ball screw mechanical efficiency, one must choice the proper preload and the screw helix angle dependent upon on the axial load and the screw rotational speed.

12 No movement mechanism friction wear, the mechanical efficiency high,[www.Sentencedict.com] this is type compressor vortex than other air compressor greatly energy saving main reason.

13 If efficiency can point to efficiency of mechanical efficiency, work efficiency, economy, wait a moment.

14 Applying the slender crankshaft, the level rolling bearing technology, and lower viscosity refrigeration oil, increased the mechanical efficiency.

15 W: We ask for full payment at sight, because we guarantee 90% mechanical efficiency for all our products. You don't have the same guarantee from other suppliers.

16 The test method of pressure loss, flow loss and frictional force loss etc. of the hydraulic pumping units is presented, from which the mechanical efficiency and volumetric efficiency are obtained.

17 W: We ask for full payment at sight, because we guarantee 90% mechanical efficiency for all our products. You don't have the same guarantee from other suppliers. The usual percentage is around 85.

18 Objective To establish noninvasive new indices for the evaluation of left ventricular(LV) work and mechanical efficiency.

19 We ask for full payment at sight because we can guarantee 90 % mechanical efficiency.

20 According to the theory of similarity, the new conversion methods of mechanical efficiency, hydraulic efficiency, cubage efficiency, pump overall efficiency and pump set efficiency are put forward.

21 In this paper a mathematical model is used for calculating mechanical efficiency and mechanical loss of direct - injection diesel engine.

22 After the movement had ended recorded (or computation) the mechanical work, and computated different movement mechanical efficiency.

23 In this method, the guaranty of higher volumetric and mechanical efficiency is regarded as the confined condition.

24 It is a intrinsic physical phenomenon of friction tape transfer for elastic slip, which leads to unstable movements for the instantaneous transmission ratio and a low mechanical efficiency.

25 However, the greater the displacement of the input shaft axis from the crown wheel axis , the lower the mechanical efficiency.
