First, the temptation to retire once Social Security benefits can be claimed, at the age of 62, seems irresistible for the majority of workers, even though the payments are actuarially reduced. Second, employers are reluctant to retain or hire older people, mainly because they find it hard to lower their wages if their productivity slips.

原因有二：一，工人到了62岁即可退休，一退休，即可领取社会保障金，多数人都难以抵挡这一诱惑（尽管据保险统计数据，支付给他们的保障金数额实际有所减少）；二，雇主不愿保留或再雇佣年纪较大的工人，主要原因是，这些雇主发现，即使这些人的生产力大不如前了，也很难把他们的工资降下来。

Hence, the empirical productivity formulas for the gas wells of relatively homogenous and aeolotropic gas reservoirs were established with the "single point testing" method respectively.

但由于忽视了单点经验产能公式的适用范围和测试条件，计算的无阻流量与修正等时试井相比，部分气井误差达 30 %以上。

From go up at all say, unifinication is afterwar technology progress and the result that productivity develops.

从根本上说，一体化是战后科学技术进步和生产力发展的结果。

But on account of excessive cut since 1949, forest resources cutdown sharply, bring a series of problem, for instance, forest productivity decrease, forest habitat fragmentation, agrestic species become extinct at a high speed, environmental quality decline, this paper discussed forest resources change in Heilongjing Province from statistical change feature of forest resources and forest landscape pattern change, using model of GM(1,1) to predict the development trend of forest resources here.

但由于半个多世纪的过量采伐，致使森林资源锐减，带来了森林生产力下降、森林生境破碎化、乡土物种加速灭绝和环境质量下降等一系列问题。本文从森林资源统计变化特征、森林景观格局变化两个方面对黑龙江省森林资源的变化进行了研究，并用灰色理论的GM(1，1)模型对该省森林资源未来的发展进行了预测。

Alcaligenes eutrophus WSH3 was selected as the strain for the production of polyβ-hydroxybutyrate and copolymer of 3-hydroxybutyrate and 3hydroxyvalerate . This study is aimed at finding an operative way leading to high PHB and PHBV productivity, high yield coefficient and high content of PHB and PHBV. The main research results are as follows

本文以真养产碱杆菌(A.eutrophus)WSH3为聚-β-羟基丁酸和3-羟基丁酸与3-羟基戊酸的共聚物的生产菌株，以实现PHB和PHBV发酵过程的高的生产强度、高的产物对基质的产率系数和高的聚合物含量为目标，进行了PHB及PHBV发酵条件的研究，主要研究内容和结果如下

Deficiency which exists in view of the existing technique of production technology, in the technique of production, this article uses the extrution casting method manufacture copper alclad semifinished materials, finally uses the hot extrusion craft, this kind of technique of production enhances the product the uniformity, thickness plasticity, the union to be reliable obviously, has the productivity to be high, the material cost is low, the product conductivity is high, merits and so on electrochemistry stable property.

针对现有生产工艺技术中存在的不足之处，在生产工艺上，本文采用挤压铸造方法制作铜包铝坯料，最后采用热挤压工艺，这种生产工艺明显地提高产品的均匀性、厚度可塑性、结合可靠，具有生产率高，材料成本低、产品导电率高、电化学性能稳定等优点。然而，铜包铝母线槽排挤压技术的研究是真正意义上的以铝节铜，在节省铜资源的方面具有十分重要的意义。
