Prior to the UML, there was no clearleading (66) Ianguage. Users had to choose from among many similar modeling languages with minor differences in overall (67) power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of (68) discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to adopt one, or a very few, broadly supported modeling languages suitable for (69) usage.

Some Vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add-on tools has been depressed because small vendors cannot afford to support many different formats from many differem (70) modeling tools. It is important to the entire OO industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.

（69）处填（）。

A．distincitive

B．special-purpose

C．separate

D．general-purpose

关于预应力构件有如下几种意见，试判断其中( )项正确，并简述其理由。

A．预应力构件有先张和后张两种方法，但无论采用何种方法，其预应力损失值的计算方法相同
B．预应力构件的延性和耗能能力较差，所以可用于非地震地区和抗震设防烈度为6度、7度和8度的地区；若设防烈度为9度的地区采用时，应有充分依据，并采取可靠的措施
C．假定在抗震设防烈度为8度地区有两根预应力框架梁，一根采用后张无黏结预应力，另一根采用后张有黏结预应力；当地震发生时，二者的结构延性和抗震性能相同
D．某8度抗震设防地区，在不同抗震等级的建筑中有两根后张预应力混凝土框架梁。其抗震等级分别为一级和二级；按规范规定，两根梁的预应力强度比限值不同，前者大于后者
