  useful output
The useful output energy and lost energy ratios of the two equivalent loss configurations are 0.54 and 0.89, respectively.
      
For the different losses of these two practical Pockels cell bias voltages, the useful output energy difference is about 30%.
      
It not only degrades the useful output energy, but introduces a useless energy loss in the reverse output direction.
      
Deviation of a practical Pockels cell Q-switch bias voltage from the ideal bias value significantly affects the extraction of useful output energy.
      
Analytic relations are obtained which explain the temperature dependence of the useful output voltage under external physical action.

Evaluation of hydraulic system of engineering machinery is not differ- rent from the examination of its performance figures (i,e.indexes of efficie- ncy,useful output,range of speed regulation and microadjustment,operation al reliability,impulse vibration,noise and safety during operation etc.) under the condition of fulfilling the requirements of static characterisic indexes.After analyzing some hydraulic systems available,the author goes further into the question and points out that these performance figures are subsequently affected by the following esssentials: (1)Number of pumps in that hydraulic system, (2)Type of pump, (3)Mode of control (4)Mode of power distribution, (5)Mode of confluence, (6)Degree of automation. By taking a hydraulic excavator as an example,in this paper,the author discusses the effects of the above essentials on the performance figures of hydraulic system.At the same time,the developing tendency of hydraulic system in engineering machinery is also mentioned。

对工程机械液压系统的评价,是指在满足静态特性指标的前提下,考核液压系统的效率、功率利用、调速范围及微调性、操纵性、冲击振动和噪声、以及安全性等方面的指标。而上述评价指标又受液压系统中液压泵的数目、型式、液压泵的控制方式、功率分配方式、合流方式及自动化程度等六个基本点的影响。本文则以上述六个基本点作为分析工程机械液压系统的要点,以液压挖掘机为例,论述其对各评价指标的影响。文中还同时提到工程机械液压系统的发展趋向。
