The main body of a book adopt the MRS culture medium flat to sift a lactobacillus , separate a purification by that 4 time of the above biography replaces it with reaching in a row,shape and rhabditiform the mirror is observed to hammer when checking up two kinds, the hammer shape is that the circle steeps a shape , become a pair or link up , assume strong point muchly catenoid existence; Long in being slender rhabditiform rhabditiform , strong arrangement of chain, large amount o'clock presents to send out the filiform congeries.

摘要本文采用MRS培养基平板筛选乳酸菌，经过连续4次以上的传代，以达到分离提纯，镜检时观察到链球状和杆状两种，链球状为圆泡状，多成对或串连，呈长链状存在；杆状为中长细杆状，链壮排列，大量时呈发丝状堆积。

RESULTS Hp can grow in liquid media in room temperature, and 3 out of 18 strains of coccoid Hp reverted to bacterial.

结果 Hp可在室温液体中繁殖，18株中观察到3株球形体Hp在室温下的返祖，除常见球形变外的Hp杆状弯曲、长杆状、短杆状、长丝体、巨球体、丝球体、原生质体及细小"S"和弧形变异。

Besides coccoid of Hp transformations, curve-bacilliform, long-bacilliform, short bacilliform, long threadlike, giant coccoid, glomerule, trophoplast, and very small "s" or "c" shaped Hp were found.

并根据Hp形态变化的顺序及表型，初步发现Hp由典型"S"或多螺旋形态变为杆状弯曲、长杆状、短杆状、然后变为球形、长丝体、巨球体、丝球体、原生质体的规律。

At impacting condition, rigid polyarethane foam, rubber, and MDF concrete exhibited static friction coefficient of 0.29, 0.285, 0.28 - 0.29, and dynamic friction coefficient of 0.25,0.24, 0.23 respectively when running against aluminum lever.

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.
