To study the clinical effect of two methods of pit and fissure sealant for preventing pit and fissure caries.

This paper listed a great number of records of dinoflagellate cysts with transapical ar-chaeopyte suture in marine and nonmarine deposits and pointed out that the cysts with this structure could be divided into two types which represented respectively two branches of later Cretaceous from marine pyrrophyta.One branch was represented by Palaeoperidi-nium with bipesioid type of reflection plate;the other was represented by Saeptodinium with bipesioid or cinctioid type of reflection plate.

摘 要：本文列举了大量具过顶古口缝的沟鞭藻囊孢在海相和非海相沉积中的记录，指出具这一构造的沟鞭藻囊孢可以细分成两个亚类，分别代表晚白垩世从海相多甲藻类家族中分化出的两个分支：一支以Palaeoperidinium为代表，具bipesioid型反映板式；另一支以Saeptodinium为代表，具bipesioid或cinctioid型反映板式。

Another village people 札 is prosperous to say:"Hide 历 mid- October in 1982, I lead river go to cloth dragon the ditch cut wood, after entering ditch smell a hoof Cape burnt bad smell, again go toward in walk a burst of, hear a rock a top 哗 suddenly 1, raise head and look, there are 2 to grow red hair of the monster stand in the mountain cave, I stunned, going toward hurriedly outside run, henceforth I got sick for 34 months."

另一位村民札旺说：&1982年藏历十月中旬，我过河去布龙沟砍柴，进沟后就闻到一股蹄角烧焦似的臭味，再往里走了一阵，忽然听到岩上哗啦一声，抬头一看，有两个长红毛的怪物站在岩洞口，我吓呆了，赶紧往外跑，此后我病了三四个月。&

The results indicates, with the same level of other parameters, the TN removal can reach 80.0% and 70.9% with the control of dissolved oxygen under the levels of 0.3-0.6mg/l and 0.6-0.9mg/l, respectively; the TN removal upgrades from 80%, 83% to 84.1% with the decrease of sludge load in the system from 0.1, 0.07, to 0.05gCOD/gMLSS·d; the nitrogen removal only reaches 58% when C/N is 4, but can reach more than 80% when C/N is at or over 7, which indicates that the TN removal increases when higher C/N ratio; when HRT increases from 12h, 18h to 24h, the TN removal also increases from 78.6%, 82.0% to 83.0%; the TN removal average in the system increases from 75.6%, 78.5% to 83.0% with the increase of sludge age from 18d, 20d to 24d; the low oxygen conditions in the modified Orbal oxidation ditch model do not decrease the effect of COD removal, and the dissolved oxygen gradient with the distribution of 0-2-1mg/l in the system ensures the COD removal reaching the range of 80%-86%; and the phosphate removal, however, is not good enough, which varies from 40% to 50%, even lower than 35% in occasional situations, and the phosphate concentration in the outflow varies in the range of 1.28-2.38mg/l, which dissatisfies the discharge standard with the level of 1.0mg/l.

试验结果表明，在其它参数相同的情况下，将外沟道的溶解氧分别控制在0.3～0.6mg/l 和0.6～0.9mg/l 两个水平，外沟道中TN 去除率分别为80.0%和70.9%；系统中污泥负荷分别为0.1gCOD/gMLSS·d、0.07 gCOD/gMLSS·d、0.05 gCOD/gMLSS·d时，随着污泥负荷的降低，TN 的去除率却是上升的，分别为80%、83%、84.1%；本试验中，当C/N 为4时，仅能获得58%的脱氮率，当C/N 为7 或更高时脱氮率能达到80%以上，进水C/N 比值越高，总氮的去除率越高；在本试验中采取的水力停留分别为12h、18h、24h 时，外沟道中的总氮去除率随水力停留时间的增加而增加，分别为78.6%、82.0%和83.0%；当系统泥龄分别为18d、20d、24d 时，系统平均TN 去除率分别为75.6%、78.5%、83.0%，随着泥龄的增大TN 的去除率增加；改良型奥贝尔模型的低氧条件并没有降低COD 的去除效果，系统0-2-1mg/l的溶解氧梯度分布使得COD 去除率一般都在80%～86%之间；本试验中磷的去除效果不好，去除率基本在40%～50%之间，有的甚至低于35%，出水磷的浓度在1.28～2.38mg/l 之间，低于1.0mg/l 的出水排放标准。
