易变的

Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

In addition, the variate C terminal part of 3A protein has been identified by sequence alignment with other FMDV strains.

序列比较显示：3A的C端易变，其它区的变易呈零星散在

Labor vanquishes all---not inconstant, spasmodic, or ill-directed labor; but faithful, unremitting, daily effort toward a well-directed purpose. Just as truly as eternal vigilance is the price of liberty, so is eternal industry the price of noble and enduring success.

英国工党征服了一切，不是易变的，间断的，错方向的努力，而是可靠的，持续的，对于一个正确的目标不断的尝试，自主权的价值所在就是像永久的失眠一样真实，所以，坚持不懈的勤奋就是高贵的不朽成就的价值所在。

The remaining three species are much more difficult, at least from herbarium material, as staminate flowers seem to offer no useful characters; leaves on flowering specimens are often young, and therefore, generally small, and in all three species the leaf shape and size is variable, with character states overlapping between the species.

Flacourtia mollis的年轻的果可以被它的叶毛被认出，剩下的3 种更难分，至少从标本馆的标本上看如此，因为雄花好像没有提供有用的特征；在花标本上的叶经常幼嫩，因此，通常小，在全部3 种中叶的形状和尺寸是易变的，在物种之间具有重叠特征状态。

Hence, the welding machines to be used for short circuiting transfer, make use of a variable choke system which can be tuned for different wire sizes, The frequency of the metal transfer may be of the order of 50 to 200 per second.

因此， 用于短路的焊接的机器转移，利用可能被为不同的电线尺寸调试的一个易变的阻塞门系统，金属的频率转移可能具有50到200 每秒的命令。

In business relations the degree of confidence must be more variable, but Prisoner's Dilemmas are nevertheless often obviated by the strength of personal relations, and this strength is a property not of the transactors but of their concrete relations.

在商业关系中，信任的程度是更加易变的。但是「囚徒困境」仍然经常由於个人关系的增加而得以消除，而且这种关系得强度并不是交易者的性质，而是他们的具体关系的性质。

Leaves variable, those on previous year's branches usually alternate, those on short branches approximate and often fascicled; petiole 1–2(–3) cm, glabrous, with 2 to 4 nectaries at apex or at base of leaf blade; leaf blade lanceolate to elliptic-lanceolate, 3–6(–9)× 1–2.5 cm, slightly pilose when young, glabrescent, base broadly cuneate to rounded, margin shallowly densely serrate, apex acute to shortly acuminate.

易变的叶，那些在通常互生的第二年分枝上，那些在短枝紧靠和通常簇生上；叶柄1-2(-3)厘米，无毛，具2在4蜜腺在先端或叶片的在基部；叶片披针形的到椭圆形披针形， 3-6(-9)* 1-2.5 浅的幼时的厘米，稍具柔毛，后脱落，基部宽楔形到圆形，边缘浓密有锯齿，先端锐尖到短渐尖。

The degree to which individuals contribute above the expected level is variable--dependent on the incumbents' skills and efforts.

个体在期望的水平之上造成的程度是易变的--新任的技能和努力的受抚养者。

Generalized reciprocal theorems of non-coupled and coupled system s, which are valid for two deformed bodies with different constitutive relations are established by generalizing the idea of Betti s reciprocal theorem.

推广Betti倒易定理的概念，建立了非耦联系统和耦联系统的广义倒易定理，它们适用于具有不同本构关系的两个变形体·当该两变形体的本构关系相同且为线弹性时，该非耦联系统的广义倒易定理即成为Betti倒易定理·同时，应用该两个广义倒易定理于弹性力学中的模拟计

When the constitutive relations of the two deformed bodies are all alike and linear elastic, the generalized reciprocal theorem of non-coupled system s just becomes Betti s.

推广Betti倒易定理的概念，建立了非耦联系统和耦联系统的广义倒易定理，它们适用于具有不同本构关系的两个变形体·当该两变形体的本构关系相同且为线弹性时，该非耦联系统的广义倒易定理即成为Betti倒易定理·同时，应用该两个广义倒易定理于弹性力学中的模拟计

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
