This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.

刮削过程。刮削工作主要是为了保证设备相互接触并摩擦的两面间能获得较高的尺寸精度、形状精度、位置精度、接触精度、传动精度和良好的润滑，因是手工操作且需反复配刮，故工作量大，耗时较长，设备不同，刮削所需时间也各不相同，例如镗床上滑座与下滑座间的配刮，刮削前先测量出二者之间原有的间隙值，然后根据工艺要求测算出需刮削值及每次的刮削量，再将红丹粉涂于上滑座之上，手工让上滑座在下滑座上来回做直线运动，使它们之间充分接触和摩擦，再用刮刀刮削摩擦产生出的接触点，如此反复多次，直至技术要求范围之内，单此项配刮需2天左右，若对于整个镗床所有配刮工作的时间总和，则需半个月左右。

该文批判了西方有关自然资源的效用论、地租论和传统马克思主义经济学中的无价论、实用论，运用马克思劳动价值论解释森林资源的价值，认为其价值量决定是由森林资源再生产中已利用的最差等级林地的以社会需要为基础的社会必要劳动时间决定的，而不是森林各种使用价值的加总，各种使用价值的价值量是一定的森林资源价值量在该使用价值上的分摊量，其价值补偿是成本补偿而不是效益补偿。

At that time, due to an immature market factors, the lack of active market, fair value is often difficult to obtain, leading enterprises in the use of these accounting criteria There is a certain arbitrariness, and thus left to the fair value of the abuse of loopholes, a profit of manipulation "Therefore, the new guidelines on the new system and operational matters dealing with the economy as much as possible by avoiding the 'fair value' pricing, according to the book value recorded." 2006 promulgated by the new accounting standards clearly require the use of fair-value model, this is not only the application of fair value measurement of financial instruments from the non-financial tools to the change, as well as for the application of fair value of a turning point - by the controversy "is used" to the "How a" turning point.

原因是由于当时要素市场不成熟，缺乏活跃的市场，公允价值往往难以获得，导致企业在运用这些会计准则时存在一定的随意性，从而也给滥用公允价值留下空子，出现人为操纵利润的情况，&因此，新准则和新制度对有关经济业务事项的处理尽可能地回避了按'公允价值'计价，而改按账面价值入账&。2006 年新颁布的会计准则明确要求采用公允价值模式，这不仅是公允价值计量的应用由金融工具向非金融工具的转变，也是对我国公允价值应用的一个转折点——由争论&是否采用&到&如何采用&的转折点。
