影响控制工作效率的因素有哪些？

根据下面内容，回答下面的题目：

我们几乎每时每刻都处在一个受噪音污染的环境中，虽然很多时候这样的声环境只是不友好，并没有达到震耳欲聋的地步，但日积月累，人们的身心健康也会受到很大影响，而且还会影响工作效率。传说的声学控制措施包括减少噪声源的声功率、在传声途径上设计障碍阻隔噪声和振动。增加建筑墙体的隔声性能，设置吸音装置等等。但生态建筑的声环境控制有别于一般的噪声控制．我们需要综合考虑影响它的因素，可能采取的措施，尽量与其他生态技术

外窗的设计也很重要，可供选用的形式有单层玻璃窗、双层玻璃窗以及双层窗。其中以双层窗的隔声效果最好。需要注意的是，为了避免两层玻璃间的耦合效应，两层玻璃最好选择不同的厚度．玻璃间的空气间隙应大于6毫米。另外，通风隔声窗的概念近年得到了推广。它采用一种特殊的双层窗构造，之间设置了类似声陷阱的结构。显然，这样的结构必然同时产生通风效率的降低和声衰减，目前如何增加通风效率，提高计权隔声量是通风隔声窗设计和改良的要点。

结合文意，依次填入划线句子“在选择时一定要兼顾功效（　　）、美学（　　）和经济（　　） 三个因素”括号里的内容，恰当的一项是：

A. 人类所处的环境指的是综合考虑了隔声与通风等因素的环境，即生态建筑的声环境

B. 生态建筑的声环境控制与一般噪声控制不同，因而传统声学控制措施都不能用于生态建筑

C. 从声环境的角度看，如果室外背景噪声低达40dB，生态建筑就不需要设计户外声屏障

D. 通风隔声窗容易导致通风效率的降低和声衰减两大弊端，所以在技术方面还亟需改良

A. 由此可诊断为轻躁症

B. 由此可诊断为躁狂症

C. 由此可诊断为躁抑症

D. 由此可诊断为神经症

E. 由此不能下任何诊断

与发达资本主义国家的股市相比，中国股市有哪些特征?

The sea looks very pretty when the sun is shining on it. It can be very rough when there is a strong wind. The sea is very big. It covers three quarters of the globe! The sea is also very deep in some places. There is one spot near the Philippines , where the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put in the sea at that place, there would still be 3 kilometers of water above it! What a deep place! In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are millions of tiny living things that float in the sea. Many fish live by eating them. The sea can be very cold. When the diver goes downwards, the sea becomes colder and colder. When the diver goes deeper, the water exerts greater pressure.

1、There is one spot near the Philippines, where the sea is as deep as ( ).

A、13 kilometers

B、 9 kilometers

C、 2 kilometers

D、 11 kilometers

2、There are millions of tiny living things that float in the sea, and( ).

A、they live by eating fish

B、they live by eating plants

C、they are good food for many fish

D、they live by eating worms

3、Which of the following statements is true? ( )

A、When the diver dives under the sea, he gets colder and colder.

B、When the diver sinks to the bottom, he is to be colder and colder.

C、When the diver sinks in the sea, he will be rather cold.

D、When the diver dives downward, the sea gets colder and colder.

4、From the information given, why has the diver to wear a diving suit? ( )

A、Because the diver is likely to be attacked by fish.

B、 Because the water at great depths is very cold.

C、 Because the salt water seems unsuitable for diver.

D、 Because the pressure of water at great depths is immense ( 巨大的 ).
