During selection of clavulanic acid producing strain, using glycerol tolerant as selection pressure can obviate low producing strain and increasing the successful rate of obtaining hith producing strain, it is better than traditional screening approach. 在克拉维酸产生菌的菌种选育过程中,应用甘油耐受量作为选择压力能有效地除去低效价菌株,提高高产变株的检出率,较传统筛选法优越。
It is suggested that the SPIM antigens with high molecular weight may easily induce hith titer anti-SPIM antibodies, produce their immune complexes and interfere with fertility. 提示大分子量SPIM抗原可能更容易诱导高效价SPIM-Ab产生,并形成抗原抗体免疫复合物干扰生育。
Hith temperature carbonization furnace is the key equipment during carbonization process. 实现这一转化的关键设备是碳化炉。
The nonlinear analytical solution to symmetrically piezoelectric laminated plate totally simply supported in a hith electric field is obtained and calculated with Ritz method. 利用Ritz法和双傅立叶级数得到四边简支对称压电层合板在高电场作用下的非线性解并进行计算。
