Based on the model calculation,an FAPP ventilation system was madein Beijing Poultry Breeding Company.Through running test and a series ofphysical and chemical characteristic measurement,the distribution of flowspeed in length,and breadth was given.The average temperatureand rel-ative humidity,the amplitude of T and RH per day of 30 days in winter,and instantaneous T and RH in 24 hours wre measured in FAPP house,com-paring house and outside,the result shew that FAPP ventilation system wassuperior to comparing house.The dust concentration and microrganism con-tent were also measured in the rearing piriod of poultry,the value in FAPPhouse was junior to comparing house.

在模拟结果的基础上，设计了一套FAPP通风系统并在北京市种禽公司原种后备场种雏舍进行了实际运行试验和一系列的理化特性参数的测试，试验给出的正压管道式送风舍纵轴方向及横截面上气流速度的分布规律与模拟结果相吻合；通过对FAPP舍、对照舍及舍外冬季30天的逐日平均温湿度、温湿度振幅以及24小时瞬时温湿度的测试分析，显示了FAPP通风系统在冬季通风中明显优于负压通风系统；在雏鸡全周期的饲养过程中还对舍内粉尘与微生物的含量进行了测试，FAPP舍的值明显低于对照舍，这一结果为FAPP通风系统的推广应用提供了实验依据。

The relation between nutritional needs of Ericerus pela and nutritional components of host plants are studied.

白蜡虫寄生的女贞枝条中有15种氨基酸含量低于不放养白蜡虫的对照枝条，只有谷氨酸、组氨酸和色氨酸3种氨基酸含量高于对照枝条，白蜡虫寄生使女贞枝条的氨基酸总量降低了28。

There are 15 amino acids of privet branches hosted by Ericerus pela lower than that comparative branches and total amino acids of privet branches decreased by 28.17% due to host of Ericerus pela. The results also showed that the growth of the female Ericerus pela needed K,Ca,Mn and Wax secretion of the male Ericerus pela needed K,Na,Ca,Mg,Fe,and Mn.

白蜡虫寄生的女贞枝条中有15种氨基酸含量低于不放养白蜡虫的对照枝条，只有谷氨酸、组氨酸和色氨酸3种氨基酸含量高于对照枝条，白蜡虫寄生使女贞枝条的氨基酸总量降低了28.17%。K、Ca、Mn 3种元素和K、Na、Ca、Mg、Fe、Mn等元素分别是白蜡虫雌虫生长发育和雄虫泌蜡所必须。

The toxicant was washed out after the isolated rat diaphragm was exposed to dDVP for 20 min,then the drugs were added; a:TCR=the height of tonic contraction of isolated rat diaphragm after DDVP and oximes/normal height

DDVP中毒20分钟后将毒剂洗掉10分钟，再加药对抗；a：TCR=毒物或药物作用后的TC高度/正常对照的TC高度；b：SCR=毒物或药物作用后的SC高度/正常对照的SC高度

The experimental teeth were prepared using the modified double-flared technique and obturated by lateral condensation and vertical condensation with AH Plus or Pulp Canal Sealer EWT sealer.

选取 70颗直根管的上前牙，根管预备后随机分为对照组(阳性对照和阴性对照各 5颗)和A、B、C、D4个试验组，A、B组用侧向加压充填技术，C、D组用垂直加压充填技术充填根管，A、C组的封闭剂为AHPlus，B、D组为PulpCanalSealerEWT。

Result: In the same chromatogram and on the same place of control herb, subject herb appeared well-separated spot, but no spots in negative control herb .

结果： 在同一薄层色谱中，和药材对照品相同的位置上，供试品显清晰分离良好的斑点，阴性对照品无此斑点。

Greenhouse pot tests showed that treatments with GJ23,NJ08 and NJ28 have greatly inhibited gall formation on tomato roots.

用GJ23，NJ08和NJ218的菌悬液进行的温室盆钵实验，结果表明不同的浓度处理均对番茄上南方根结线虫的根结形成有显著的抑制作用，其中2倍菌液处理的平均根结数比对照分别少51.4%、62.5%和54.5%；它们还对番茄的生长有明显促进作用，2倍稀释菌液处理组的番茄冠重分别比对照高39.8%、32.0%和60.5%。

The results showed that as compared with the equal chemical fertilizer (T2), tobacco special fertilizer could improve the physical character of soil and ensure growth steadily to form perfect plant figure.

结果表明：与等氮磷钾养分对照(T2)比较，烟草专用肥处理(T4)可以改善土壤的物理性状；有利于烟株稳健生长，形成理想的株型；降低烟叶的蛋白质含量、减小两糖差值，糖碱比和氮碱比更加适宜，改善烟叶品质；但是烟叶产量、中上等烟叶产量与等氮磷钾养分对照相似。

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。
