反应系数

The results showed that the substrate concentration and temperature were important factors which influenced the rate - controlling step. The results of model calculated with effective diffusion coefficient...

结果表明，底物浓度和反应温度是影响速率控制步骤的重要因素，用得到的有效扩散系数进行模型计算，结果与实验值基本一致。

The study shows that the activation energy of most shell is 1/3-2/3 of the limestone, the product-layer coefficient magnitude is 1 magnitude higher than that of limestone, and the specific surface area, specific pore volume, and the average pore radius are all bigger than that of limestone. So shells are fit for coal combustion sulfur retention in high temperature (900-1000℃).

贝壳与石灰石的比较性实验表明：大部分贝壳的固硫反应活化能是石灰石的1／3-2／3，产物层扩散系数比石灰石高出一个数量级，内部微观结构如比表面积、比孔容、最可几孔半径等都比石灰石大，贝壳更适合作高温（900℃-1000℃）下的燃煤固硫剂。

It is important to understand the tar evolving and cracking behavior in the fluidized bed gasifier. With peanut shell, rice straw and saw dust as raw materials, the gasification was carried out in a pilot scale fluidized bed gasifier at variant temperatures (750℃~850℃), air equivalence ratio (0.15~0.35) and catalyst addition. Simultaneously, tar component was analyzed using gas chromatograph with mass selective detector.

为了了解生物质流化床气化过程中焦油的析出和脱除特性，以花生壳、稻草以及木屑为原料，采用流化床气化反应系统，研究了气化温度(750℃~850℃)、空气当量系数(0.15~0.35)以及催化剂（白云石、橄榄石与菱镁矿）的添加等对气体产物中焦油的析出组成特性的影响，并采用色谱-质谱联用仪对焦油的主要成分进行了分析。

RESULTS:The degradations of N1-sorbyl-5-Fu were shown to display pseudo-first-order kinetics in buffer solutions and biological media.

结果： N1-山梨酰-5-氟脲嘧啶在缓冲溶液和组织匀浆中的降解服从表观一级反应，分配系数logP=1.5780。

The total field deratization rate was 98.02%,the corrected total field deratization rate was 98.17%;when continuously providing poison bait 3 d,the mortality rate of rabbit and chicken was 40% and 20% respectively,while continuously providing 5 d,the mortality rate was 100% and 80% respectively.When feeding cat continuously 3 d with poisoned mouse and domestic dog continuously 2 d with poisoned brown rat,no poisoning occurred.

结果 摄食系数为0.73，实验室灭鼠率为100%；农村、食堂、饭店、食品超市、食品加工厂的现场灭鼠率分别为97.61%、97.43%、97.71%、100%和100%，现场总灭鼠率为98.02%，现场总校正灭鼠率为98.17%；连续给药3 d，家兔、鸡的死亡率分别为40%和20%；连续给药5 d，家兔、鸡的死亡率分别为100%和80%；给家猫连续3 d喂食中毒的小白鼠，犬连续2 d喂食中毒的褐家鼠，均未见中毒反应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
