查询词典 null ellipse

Null mutant Δmnh6 produced appeared offwhite hyphae, showed reduction in growth, conidiation and appressorium formation, and also showed reduction in appressorium turgor pressure. And the hyphae were more readily wettable by a solution containing SDS and EDTA and more easily digested by fungal cell-wall-digesting enzymes. The appressoria produced by Δmnh6 mutants showed diminished host penetration and the infectious hyphae of Δmnh6 mutants showed reduced in planta growth. Targeted deletion of mnh6 resulted in the greatly reduced virulence capacity to barley and rice CO39 in infection assays.

突变子Δmnh6的菌落形态不同于野生型GUY11，菌落呈灰白色，菌丝稀疏，生长速度变慢，产孢菌丝细胞壁的溶剂疏水性消失，菌丝细胞壁容易被细胞壁降解酶降解，产孢减少，孢子形态变得细长，孢子的附着胞形成率降低，附着胞的膨压降低，附着胞对寄主植物表面的穿透能力减弱，侵入后生长速度减慢，喷雾接种后对大麦和水稻CO39的致病性消失。mnh6基因重新引入Δmnh6后，突变子的表型恢复。

Rather, this initial crosscountry analysis fails to reject the null hypothesis that the relative size of the SME sector per se does not exert a causal impact on growth or poverty alleviation.

相反地，这种初步的跨国别分析没有摈弃如下这种零假设，即中小企业部门本身的相对规模不对增长或消除贫困产生一种因果关系的作用。

If the decremented reference count is positive, we return a null pointer so that delete leaves our object alone.

如果引用计数是整数，我们返回一个空指针使delete不处理我们的对象。

When we return a card, we can actually remove it from the ArrayList, thus decrementing the size, leaving us with a collection that only has cards left in it (as opposed to just replacing its spot with the last card in the array, and setting the last spot to null).

当我们返回一个卡，我们实际上可以删除ArrayList的事，因此递减的规模，留下了只有在离开卡（而不仅仅是替换数组中的最后一张牌的位置，我们收集，并设置最后的位置为空）。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。
