D.应急预案的制定要考虑在实施应急救援过程中可能产生的新伤害和损失

答案

参考答案:C

解析:应急预案是对特定的潜在事件和紧急情况发生时所采取措施的计划安排,是应急响应的行动指南。编制应急预案的目的,是防止一旦紧急情况发生时出现混乱,能够按照合理的响应流程采取适当的救援措施,预防和减少可能随之引发的职业健康安全和环境影响。应急预案的制定,首先必须与重大环境因素和重大危险源相结合,特别是与这些环境因素和危险源一旦控制失效可能导致的后果相适应,还要考虑在实施应急救援过程中可能产生的新的伤害和损失。

As one works with color in a practical, or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile, changeable thing (1) to a large extent on the relationship of the color (2) other colors (3) simultaneously. It is not (4) in its relation to the direct stimulus which (5) it. On the other hand, the properties of surfaces that give (6) to color do not seem to change greatly under a wide variety of illumination color, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be (7) in large part to the mechanism of color (8) .

When the eye is (9) to a colored area, there is an immediate readjustment of the (10) of the eye to color in and around the area (11) . This readjustment does not promptly affect the color seen but usually does affect the next area to which the (12) is shifted. The longer the time of viewing, the higher the (13) , and the larger the area, the greater the effect will be (14) its persistence in the (15) viewing situation. As indicated by the work of Wright and Schouten, it appears that, at (16) for a first approximation, full adaptation takes place over (17) time if the adapting source is moderately bright and the eye has been in (18) darkness just previously. Also, (19) of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become (20) over the whole eye.
