The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.

有机肥还具有提高土壤易氧化碳和松结态腐殖质含量，降低kos值，提高土壤HA、FA含量及其比值的作用，使土壤中有效态氮、磷、铁、锰、铜和锌含量处于中上等水平；长期秸秆还田除了不增加土壤全磷、有效氮和磷等外，对其他养分的作用效果与有机肥相似，但其肥效不如有机肥；长期氮磷化肥单施，土壤全氮和磷增加，有机质、铁、锰、铜和锌含量下降，易氧化碳、松结态腐殖质、HA和FA含量、kos和HA/FA值下降；长期不施肥土壤有机质、全氮等养分处于消耗状态。

With increasing of salinity, there were no obvious difference in quantity and shape of chloroplast under SEM, but their location in palisade cells occurred change. All these changes made seedlings photosynthesis inhibited and growth stunted.

因此，盐胁迫下叶片栅栏组织厚度的下降、海绵组织中胞间隙的减少以及叶肉细胞中叶绿体的分布变化可能是导致植物光合效率下降和幼苗生长受阻的重要原因。

Challenge was made after one month of immunization by vein. Re sults:The parasitemia of recombinant virus immunized monkey was 0.0 1%in first tw o days of post-challenge. No parasites were determined from third to 12th day. W hereas the parasitemia of control virus immunized-monkey and blank control monk ey rose progressively,went to 2.5%～6.0% at 6th～8th days of post-challenge, an d the t ime of parasitemia was 12～13 days.

结果： 在免疫后1个月攻虫，重组痘苗病毒免疫猴从第3天一直到第12 d的采血检查中均未发现疟原虫；非重组痘苗病毒免疫猴第3天后原虫感染率上升，第6天原虫感染率最高达到6.0%，而后原虫感染率逐渐下降，原虫持续时间为13天；空白对照猴第3天后原虫感染率也上升，第8天原虫感染率最高达到2.5%，而后原虫感染率逐渐下降，原虫持续出现时间为12 d。

PYLLS and rate of PYLL of the eight causes of death and all causes of death decreased with time, and the decrease of infectious deseases, parasitosis and nerve system diseases are rapidly, but tumor decreased slowly.

结论］8类主要死因和全死因的PYLL率随时间均下降，其中，传染病与寄生虫病、神经系统疾病的PYLL率下降程度最大，而肿瘤最小。

The parent training program was designed based on the results of interview and testing. 45 adolescents' parents took part in the family intervention program.

根据访谈和测查结果设计了针对父母的干预课程，有45名青少年的父母参加了父母培训的家庭干预项目，干预的结果显示干预组的青少年抑郁分数有显著的下降，羞耻的分数显著下降，但是自尊的分数没有改变。

Our results indicate that the overall crime rate in Taiwan dec1ined significantly after the implementation of the new parole policy. This is reflected in both misdemeanor and felony crimes. We also find that both the overall recidivism rate and the parolee recidivism rate dec1ined significantly after the implementation of the new policy.

研究结果显示，台湾实施新的假释政策后，整体犯罪率显著下降，包括轻罪与重罪，结果也发现新的假释政策实施后，累犯率和假释犯再犯率大幅下降。

Nordstrom's sales are down almost 16%, JC Penney's dropped 13%.

Nordstrom 的销售几乎下降 16%，而杰西潘妮则下降了 13%。

Achieve cast market investment to drop to basically have the following reasons: Above all, investment case amount dropped considerably in July basically is to suffer achieve cast an industry to invest periodic element to affect.

创投市场投资下降主要有以下几个原因：首先，7月投资案例数量大幅下降主要是受创投行业投资周期因素影响。

Results The value of ANP in purulent meningitis appear downtrend and depend upon its descended,show us different clinical complication,the lowness is the brain abscess and brain ependymitis,analyse from pathogeny,the lowness is the pneumococcus and sanguinary flu bacilus.

结果 ANP值在化脑时呈下降趋势，其下降水平不同，临床所表现出的并发症不同，以脑脓肿、脑室管膜炎ANP值最低；从病原学上分析肺炎双球菌、嗜血流感杆菌ANP值最低。

The contents of Chla and Car were sensitive to low temperature stress, it seems that they were vulnerable to low temperature stress and partly decomposed. Relatively, the content of Chlb changed little. The ratio of Chla/b had positive linear correlation with temperature, which meant the photosynthetic ability of podocarpus fleuryi Hickel seedlings declined under winter low temperature stress.

叶片中叶绿素a和类胡萝卜素含量对低温胁迫反应较为敏感，容易遭受低温胁迫而部分地分解破坏，含量下降，而叶绿素b则相对变化较小，Chla／b值呈现与温度的线性正相关，显示了长叶竹柏幼苗在冬季低温胁迫下光合能力的下降情况。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
