复方碘口服溶液是一种液体制剂,其处方为:碘50g,碘化钾100g,水适量制成。1000ml其制法:取碘与碘化钾,加水100ml溶解后,再加适量的水使成1000ml,即得。

提示:药物溶解度是制备药物制剂时首先掌握的必要信息,也直接影响药物在体内的吸收与药物生物利用度。下述影响药物溶解度的因素及增加药物溶解度的方法,哪些是错误的()

A.药物在溶剂中的溶解度是药物分子与溶剂分子间相互作用的结果,若药物分子间的作用力大于分子与溶剂分子间的作用力则药物溶解度小;反之,则溶解度大,即相相似相溶

B.多晶型现象在有机药物中广泛存在,晶型不同,溶解度也不同。无定型为无结晶结构的药物,其溶解度较结晶型小

C.对于可溶性药物,粒子大小对溶解度影响不大

D.溶解过程是放热时,溶解度均随温度升高而增大

E.多数药物为有机弱酸、弱碱及其盐类,这些药物在水中的溶解度受pH值影响不大

F.一般向难溶性盐类饱和溶液中加入含有相同离子化合物时,其溶解度降低,这是由于同离子效应的影响

G.加入助溶剂、增溶剂,可增加药物的溶解度

答案

参考答案:B, D, E

At exactly eleven Sir Percival knocked and entered, with anxiety and worry in every line of his face. This meeting would decide his future life,and he obviously knew it.

"You may wonder, Sir Percival,”said Laura calmly, “if I am going to ask to be released (免除)from my promise to many you. I am not going to ask this. I respect my father's wishes too much.”

His face relaxed a little, but one of his feet kept beating the carpet.

"No, if we are going to withdraw. (退出)from our planned marriage, it will be because of your wish, not mine.

     The story of how the song Happy Birthday to You came to be, began as a sweet one, that later

soured. Two sisters, Mildred Hill, a teacher at the Louisville, Kentucky Experimental Kindergarten, and

Dr. Patty Hill, the headmaster of the same school, together wrote a song for the children, named Good

Morning to All. As the local expert on spiritual songs, and as the organist(风琴师) for her church,

Mildred combined her musical talents with her sister's knowledge in the area of Kindergarten Education,

Good Morning to All was sure to be a success.  

     The sisters published the song in a collection called "Song Stories of the Kindergarten" in 1893.

Thirty-one years later, after Dr. Patty Hill became the head of the Department of Kindergarten Education

at Columbia University's Teacher College, a gentleman by the name of Robert H. Coleman published the

song, without the sisters' permission. What was worse, he added a second lyric, the familiar Happy

Birthday to You

     Mr. Coleman's addition of the second lyric made the song famous and popular and, eventually, the

sisters' original first lyric disappeared. Happy Birthday to You the one and only birthday song, had

altogether replaced the sisters' original title Good Morning to All.

     After Mildred died in 1916, Patty, together with a third sister named Jessica, discussed the issue
