When the volumetric ratio of medium to flask was 0.20 and the corn steep liqud concentration was 8g/L, there have high yield of pyruvate and lactate produced at growth phase, 4.1g/L and 1.0g/L, respectively, which are ...

在装液比为 0 2和玉米浆浓度为 8g L时，丙酮酸和乳酸在细胞生长期可分别积累达 4 1g L和 1 0g L ，比正常发酵时增加 2倍以上，丙三醇产率也低；然而，装液比为 0 0 8和玉米浆浓度为 4g L时，丙酮酸和乳酸产生较低，丙三醇产率较高，但乙酸积累比供氧不足时高，可达 2 6g L。

The simulated distribution of the volume fraction of vapor phase under different outlet pressure and the variation of the cavitation flow ratio indicate that the intensity of cavitation is varied with the outlet pressure of the jet pump when driving pressure and suction pressure are fixed.

模拟所得到的不同出口压力下的气相体积分数分布以及汽蚀流量比的变化表明：当射流泵工作压力与吸入压力固定时，射流泵出口压力越低，汽蚀流量比越小，同时流量比越接近汽蚀流量比，空化也越严重。

Order a carafe of house wine instead of a bottle of fine wine (saves $20 in Rome). Choose a two-star hotel rather than a three-star one (saves $60 per night in Paris). Buy the transit pass rather than individual tickets (saves $5 per ride on London's Tube). Buy a scratch-off phone card at a European newsstand for calls home, and you'll pay pennies rather than dollars per minute.

来回去机场坐公交比打车省钱（节省40美元，在维也纳），点那种与饭菜搭售的酒比单点一瓶好酒便宜（节省20美元，在罗马），选择二星级酒店比选择三星级酒店好（每晚节省60美元，在巴黎），购买国境通行证比单个人的票要好（节省5美元，在伦敦地铁），从欧洲那种报亭买刮式电话卡给家里打电话，每分钟只要几便士，而不是几美元。

Methods: 30 SPF rats were randomly divided into the health group by tail veins with saline, the doxoruvicin group with doxoruvicin and the aclarubicin group with aclarubicin.

将30只SPF级纯系SD大鼠随机分为3组，正常组尾静脉注射生理盐水，多柔比星组和阿柔比星组尾静脉分别注射多柔比星和阿柔比星。

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。

Under spraying humidification state, the parameters of JYPW-1 spraying axial fans for textile enterprises such as flow, total pressure, efficiency, shaft power and acoustic power level changing with water-air ratio were tested, and the performance parameter curve changing with water-air ratio was obtained. The approximate formula of its pneumatic performance in different water-air ratio condition were deduced which can be referenced for of selection and project application.

The temperature rising mechanisms of manganese carbonate fines containing coal by microwave heating were discussed. The results show that, manganese carbonate fines containing coal have good characteristics of microwave heating and self-reduction. At the molar ratios of C atom to O atom as 1.1, 1.2 and 1.3 in the mixed materials, the averaged maximum temperature-rising rate of the mixed materials by microwave heating is 140.7 K/min at 1 473 K with the microwave frequency of 2.450 GHz. At the different containing coal ratios and heating temperatures, the value of the dielectric constant is big, 5.5, but that of the permeability is about 1, so the mixed materials belong to dielectric loss. The temperature rising performance depends chiefly upon the electromagnetic performance of materials, whose change is caused primarily by the chemical reaction, the changes of crystal structural , and the changes of defects state. The bigger the containing coal ratio, the better the absorptivity of microwave. At the same containing coal ratio, the higher the heating temperature, the weaker the absorptivity of microwave.

研究结果表明：含碳碳酸锰矿粉具有优良的微波加热特性和自还原性；在微波加热频率为2.450 GHz、碳氧原子摩尔比分别为1.1，1.2和1.3时，微波加热混合物料至1 473 K的升温速率平均最高达到140.7 K/min；不同的加热温度和配碳比下混合物料的介电常数较大，都在5.5左右，而磁导率为1左右，属介电损耗型；微波加热含碳碳酸锰矿粉的升温性能主要取决于含碳碳酸锰矿粉的电磁性能，而电磁性能的改变主要是由物料加热过程中产生的化学反应、晶体结构变化及缺陷状态的改变引起的；配碳比提高，物料吸收微波的能力有所提高；在相同的配碳比下，加热温度升高，吸收微波的能力有所减弱。

The HA sinter with optimal strength and porosity could be obtained when HA was mixed with 1 of fold sucrose which was used as filler while binder and 1 of fold salt as filler, pressed under 5-45 kgf/cm2 force, dissolved the sucrose at 220°C, and then sintered under 1345°C for 10h.
