In order to study the digestion of fibrous materials ADF and NDF,the alfalfa,ryegrass and their powder mixture were chosen as the substrates,and mixed with the cecum chyme filtrate for fermentation.pH value declined to 6.9 during first three hours fermentation,and then came to be stable.

以苜蓿草粉、黑麦草粉和混合草粉(质量比为1∶1)为底物，接种鹅盲肠食糜滤液进行体外培养。试验结果为：培养液pH值在0~3 h下降到6.9左右，后逐渐趋于稳定；苜蓿草粉ADF、NDF和半纤维素的消失率分别为1.15%，1.18%，-0.19%；黑麦草粉三者的消失率分别为1.45%，9.05%，3.07%；而混合草粉三者的消失率分别为15.72%，13.2%，9.87%。与单一草粉的ADF、NDF和半纤维素的消失率都有显著差异(P.05)。

"Exception No.1: A unit having resistive circuity , high-impedance winding , and the like , not subject to excessive secondary-voltage build-up in case of electrical breakdown during the test may be tested :"

"例外1：具有电阻性电路，高阻抗绕组以及类似物在测试时由于电击穿可能产生过高次级电压的电源单元，可以按下列方法试验："

To study changes of the activity of iNOS in the liver and the concentration of NO in blood serum and NO' effect on inhibiting or killing coccidia,rabbits infected with Eimeria stiedai were injected with different concentrations of the substrate of NOS—L—Arg and the inhibitor of iNOS—L—AG through the abdominal cavity.

本试验以腹腔注射的途径给予斯氏艾美耳球虫感染家兔不同浓度的一氧化氮合酶底物L-精氨酸和诱导型一氧化氮合酶抑制剂L-氨基胍，对家兔球虫感染时血清中NO浓度和肝的iNOS活性及各试验组家兔的病变进行了研究。

The third chapter is mainly concerned with the physical model tests of static ice loads on conical structures.

第三章是关于模型冰排对正倒锥体结构物静力作用的物理模拟试验研究。

Biohydrogen production from corncob by dark fermentation was reported for the first time.

在批式培养试验中，以牛粪堆肥为天然产氢菌源，玉米芯为底物，通过厌氧发酵生产氢气。

Appressoria were latent in intercellular cleft and were latent until banana fruit were harvested.The development process of conidia of Colletotrichum musae on fruit was not distinct from foliage and stalk.Two pairs of PCR primers were designed according to the two especial fragment (357bp and 206bp) of Colletotrichum musae. Banana tissue culture seedling genomic DNA, banana anthracnose pathogen genomic DNA, mango anthracnose pathogen genomic DNA, rubber anthracnose pathogen genomic DNA,watermelon anthracnose pathogen genomic DNA, banana crown rot pathogen genomic DNA, stylo anthracnose pathogen genomic DNA, watermelon Fusarium wilt pathogen genomic DNA were extracted using SDS method.

根据香蕉炭疽菌的两个特异片段(分别为357bp和206bp)，设计两对引物：采用SDS法分别提取了香蕉组培苗基因组DNA、香蕉果实炭疽菌弱致病株Z_1基因组DNA、香蕉果实炭疽菌强致病株Z_4基因组DNA、芒果炭疽菌基因组DNA、橡胶炭疽菌基因组DNA、柱花草炭疽菌基因组DNA、西瓜炭疽菌基因组DNA、香蕉冠腐病菌基因组DNA、西瓜枯萎病菌基因组DNA；以上述基因组DNA为模板对特异片段进行PCR验证，证明357bp的片段为Colletotrichum musaes所特有，可以用此片段进行香蕉果实炭疽病的分子检测试验，。

But systematic research concerning continuous mono-cropping grafted cucumber obstacle isn't reported. This paper systematically studied the effect of continuous cropping soil on grafted cucumber in aspect of its growth, yield and edaphon in pot experiments. Further more, root exudates of squash and grafted cucumber were collected by solution cultivate and adsorption of XAD-4 resins, and bioassay of the root exudates was did with cucumber and squash as receptors, studied allelopathy of grafted cucumber and squash root exudates on cucumber and squash , physiobiochemistry as well as.

本项研究采用盆栽试验以不同连作年限的土壤为基质比较系统地研究了连作年限对嫁接黄瓜的生长、产量和土壤微生物的影响；采用水培和XAD-4树脂吸附法分别收集嫁接黄瓜和砧木南瓜的根系分泌物并以黄瓜、南瓜为受体进行生物活性测定，并对嫁接黄瓜及其砧木南瓜根系分泌物化感作用的生理机制进行了初步探索。
